django-dynamic-workflows 1.0.3

A powerful, configurable Django package for implementing dynamic multi-step workflow processes with database-stored actions

Django Dynamic Workflows

A powerful, configurable Django package for implementing dynamic multi-step workflow processes with database-stored actions and approval flows.

Features

• Generic Workflow Attachment: Attach workflows to any Django model without hardcoded relationships
• Database-Stored Actions: Configure actions dynamically in the database with inheritance system
• Action Inheritance: Stage → Pipeline → Workflow → Default action hierarchy
• Approval Flow Integration: Built on top of django-approval-workflow package
• Configurable Triggers: Actions triggered on workflow events (approve, reject, delegate, etc.)
• Default Email Actions: Smart email notifications to creators and approvers
• Dynamic Function Execution: Execute Python functions by database-stored paths
• Admin Interface: Rich Django admin for managing workflows, stages, and actions

Installation

pip install django-dynamic-workflows

Quick Start

1. Add to INSTALLED_APPS:

INSTALLED_APPS = [
    ...
    'approval_workflow',  # Required dependency
    'django_workflow_engine',
    ...
]

2. Run migrations:

python manage.py migrate

3. Register a model for workflow support:

from django_workflow_engine.services import register_model_for_workflow
from myapp.models import Ticket

register_model_for_workflow(
    Ticket,
    auto_start=True,
    status_field='workflow_status',
    stage_field='current_stage'
)

4. Attach and start a workflow:

from django_workflow_engine.services import attach_workflow_to_object

attachment = attach_workflow_to_object(
    obj=my_ticket,
    workflow=my_workflow,
    user=request.user,
    auto_start=True
)

Core Concepts

WorkFlow, Pipeline, Stage Hierarchy

• WorkFlow: Top-level workflow definition
• Pipeline: Departments or phases within a workflow
• Stage: Individual approval steps within a pipeline

Configurable Actions

• Database-stored function paths executed on workflow events
• Inheritance system: Stage overrides Pipeline overrides Workflow overrides Default
• Support for parameters and custom context

Action Types

• AFTER_APPROVE: After approval step completion
• AFTER_REJECT: After workflow rejection
• AFTER_RESUBMISSION: After resubmission request
• AFTER_DELEGATE: After delegation to another user
• AFTER_MOVE_STAGE: After moving between stages
• AFTER_MOVE_PIPELINE: After moving between pipelines
• ON_WORKFLOW_START: When workflow begins
• ON_WORKFLOW_COMPLETE: When workflow completes

Custom Actions

The Django Workflow Engine supports powerful custom actions that execute automatically at key workflow events. Actions can send emails, update external systems, create tasks, log events, and more.

Quick Example

# myapp/workflow_actions.py
def send_approval_notification(context, parameters=None):
    """Send email when stage is approved"""
    attachment = context['attachment']
    user = context.get('user')

    recipients = parameters.get('recipients', [])

    send_mail(
        subject=f"Stage '{attachment.current_stage.name_en}' Approved",
        message=f"Approved by {user.get_full_name()}",
        from_email='[e-mail]',
        recipient_list=recipients,
    )

    return {"email_sent": True}

# Register in Django Admin or code:
from django_workflow_engine.models import WorkflowAction
from django_workflow_engine.choices import ActionType

WorkflowAction.objects.create(
    stage_id=1,  # Specific stage
    action_type=ActionType.AFTER_APPROVE,
    function_path='myapp.workflow_actions.send_approval_notification',
    parameters={'recipients': ['[e-mail]']},
    order=1,
    is_active=True
)

Action Types & Timing

Action Type	When Triggered	Use For
AFTER_APPROVE	After stage approval	Approval notifications, logging
AFTER_MOVE_STAGE	After moving to next stage	Status updates, task creation
AFTER_MOVE_PIPELINE	After moving to next pipeline	Role changes, permissions
ON_WORKFLOW_START	When workflow starts	Initial setup, notifications
ON_WORKFLOW_COMPLETE	When workflow finishes	Final actions, cleanup
AFTER_REJECT	After rejection	Rejection handling
AFTER_RESUBMISSION	After resubmission	Resubmission handling

Action Execution Order (Conflict Prevention)

The system prevents conflicts by executing actions in a specific order:

1. AFTER_APPROVE          ← Approval completed (sees current stage)
2. AFTER_MOVE_PIPELINE    ← Pipeline transition (if needed)
3. AFTER_MOVE_STAGE       ← Stage transition (sees new stage)
4. Start next stage approval flow

Available Role Selection Strategies

When configuring role-based approvals:

from approval_workflow.choices import RoleSelectionStrategy

# Available strategies:
'anyone'       # Any user with the role can approve
'consensus'    # ALL users with the role must approve
'round_robin'  # Rotate approval among role users

Complete Example: Purchase Request Workflow

This example demonstrates a complete workflow from A to Z with 2 pipelines and multiple stages.

Scenario: Purchase Request Process

• Pipeline 1 (Finance Department): Initial Review → Budget Approval → Final Finance Sign-off
• Pipeline 2 (Management): Executive Approval

Step 1: Setup Models

# models.py
from django.db import models
from django.contrib.auth.models import User

class PurchaseRequest(models.Model):
    title = models.CharField(max_length=200)
    amount = models.DecimalField(max_digits=10, decimal_places=2)
    description = models.TextField()
    requester = models.ForeignKey(User, on_delete=models.CASCADE)
    created_at = models.DateTimeField(auto_now_add=True)

    # Workflow fields
    workflow_status = models.CharField(max_length=50, default='pending')
    current_stage = models.CharField(max_length=100, blank=True)

    def __str__(self):
        return f"Purchase Request: {self.title} - ${self.amount}"

Step 2: Register Model for Workflow

# apps.py or management command
from django_workflow_engine.services import register_model_for_workflow
from .models import PurchaseRequest

register_model_for_workflow(
    PurchaseRequest,
    auto_start=True,
    status_field='workflow_status'
    # Note: No stage_field needed - use get_current_stage(instance) helper instead
)

Step 3: Create Workflow Structure Using Serializers

# Create via API serializers (recommended) or Django Admin
from django_workflow_engine.serializers import WorkFlowSerializer, StageSerializer
from django_workflow_engine.models import WorkFlow, Pipeline, Stage
from rest_framework.request import Request

# 1. Create Workflow with Pipelines using WorkFlowSerializer
workflow_data = {
    'name_en': 'Purchase Request Approval',
    'name_ar': 'موافقة طلب الشراء',
    'company': 1,
    'is_active': True,
    'pipelines': [
        {
            'name_en': 'Finance Review',
            'name_ar': 'مراجعة مالية',
            'department_id': 1,  # Finance Department
            'order': 1,
            'number_of_stages': 3  # Will auto-create 3 stages
        },
        {
            'name_en': 'Executive Approval',
            'name_ar': 'موافقة تنفيذية',
            'department_id': 2,  # Management Department
            'order': 2,
            'number_of_stages': 1  # Will auto-create 1 stage
        }
    ]
}

# Create workflow with auto-generated stages
context = {'request': request, 'company_user': company_instance}
workflow_serializer = WorkFlowSerializer(data=workflow_data, context=context)
if workflow_serializer.is_valid():
    result = workflow_serializer.save()  # Returns workflow with pipelines and stages
    purchase_workflow = WorkFlow.objects.get(id=result['id'])

# 2. Configure Stage Approvals and Forms
# Now configure each stage with approval requirements, roles, and forms
from django_workflow_engine.serializers import StageSerializer

# Get the auto-created stages
finance_pipeline = purchase_workflow.pipelines.get(name_en='Finance Review')
executive_pipeline = purchase_workflow.pipelines.get(name_en='Executive Approval')

# Configure Finance Stage 1: Initial Review
initial_review = finance_pipeline.stages.get(order=1)
stage_config = {
    'stage_info': {
        'color': '#3498db',
        'approvals': [
            {
                'approval_type': 'ROLE',  # Role-based approval
                'user_role': 1,  # Finance Reviewer Role ID
                'role_selection_strategy': 'RANDOM',
                'required_form': 1  # Initial Review Form ID
            }
        ]
    }
}

stage_serializer = StageSerializer(initial_review, data=stage_config, partial=True)
if stage_serializer.is_valid():
    stage_serializer.save()

# Configure Finance Stage 2: Budget Approval
budget_approval = finance_pipeline.stages.get(order=2)
stage_config = {
    'stage_info': {
        'color': '#f39c12',
        'approvals': [
            {
                'approval_type': 'ROLE',
                'user_role': 2,  # Budget Manager Role ID
                'role_selection_strategy': 'anyone',
                'required_form': 2  # Budget Approval Form ID
            }
        ]
    }
}

stage_serializer = StageSerializer(budget_approval, data=stage_config, partial=True)
if stage_serializer.is_valid():
    stage_serializer.save()

# Configure Finance Stage 3: Final Finance Sign-off
finance_signoff = finance_pipeline.stages.get(order=3)
stage_config = {
    'stage_info': {
        'color': '#27ae60',
        'approvals': [
            {
                'approval_type': 'USER',  # Specific user approval
                'approval_user': 123,  # CFO User ID
                'required_form': 3  # Final Approval Form ID
            }
        ]
    }
}

stage_serializer = StageSerializer(finance_signoff, data=stage_config, partial=True)
if stage_serializer.is_valid():
    stage_serializer.save()

# Configure Executive Stage: Executive Approval
executive_approval = executive_pipeline.stages.get(order=1)
stage_config = {
    'stage_info': {
        'color': '#8e44ad',
        'approvals': [
            {
                'approval_type': 'ROLE',
                'user_role': 3,  # Executive Role ID
                'role_selection_strategy': 'SUPERVISOR'
                # No required_form - executives can approve without additional forms
            }
        ]
    }
}

stage_serializer = StageSerializer(executive_approval, data=stage_config, partial=True)
if stage_serializer.is_valid():
    stage_serializer.save()

Step 4: Start Workflow (A → Z Process)

# views.py
from django_workflow_engine.services import attach_workflow_to_object

def create_purchase_request(request):
    # Create purchase request
    purchase_request = PurchaseRequest.objects.create(
        title=request.POST['title'],
        amount=request.POST['amount'],
        description=request.POST['description'],
        requester=request.user
    )

    # Attach and start workflow
    attachment = attach_workflow_to_object(
        obj=purchase_request,
        workflow=purchase_workflow,
        user=request.user,
        auto_start=True,
        metadata={
            'amount': float(purchase_request.amount),
            'priority': 'normal',
            'department': 'finance'
        }
    )

    # At this point:
    # - Purchase request is at "Initial Review" stage
    # - Current pipeline: Finance Review
    # - Status: "in_progress"

    return purchase_request

Step 5: Progress Through Workflow

# Helper function to get current stage (replaces stage_field dependency)
from django_workflow_engine.services import get_current_stage, get_workflow_attachment

def get_current_stage_info(purchase_request):
    """Get current stage information for purchase request"""

            'current_pipeline': attachment.current_pipeline,
            'stage_name': attachment.current_stage.name_en if attachment.current_stage else None,
            'pipeline_name': attachment.current_pipeline.name_en if attachment.current_pipeline else None
        }
    return None

# Use WorkflowApprovalSerializer (based on existing CRM implementation)
from django_workflow_engine.serializers import WorkflowApprovalSerializer

# FINANCE PIPELINE - STAGE 1: Initial Review
def approve_initial_review(request, purchase_request_id):
    purchase_request = PurchaseRequest.objects.get(id=purchase_request_id)

    # Check current stage
    stage_info = get_current_stage_info(purchase_request)
    print(f"Current stage: {stage_info['stage_name']} in {stage_info['pipeline_name']}")

    serializer = WorkflowApprovalSerializer(
        instance=purchase_request,  # Use instance, not object_instance

                'budget_code': 'BDG-2024-001'
            }
        },
        context={'request': request}
    )

    if serializer.is_valid():
        serializer.save()
        # ✅ Automatically moves to: Finance Pipeline → Budget Approval stage

# FINANCE PIPELINE - STAGE 2: Budget Approval
def approve_budget(request, purchase_request_id):
    purchase_request = PurchaseRequest.objects.get(id=purchase_request_id)

    serializer = WorkflowApprovalSerializer(
        instance=purchase_request,
        data={
            'action': 'APPROVED',
            'form_data': {
                'budget_manager_comment': 'Budget approved - sufficient funds available',
                'allocated_budget': '50000.00'
            }
        },
        context={'request': request}
    )

    if serializer.is_valid():
        serializer.save()
        # ✅ Automatically moves to: Finance Pipeline → Final Finance Sign-off stage

# FINANCE PIPELINE - STAGE 3: Final Finance Sign-off

                'finance_ref': 'FIN-2024-PR-001'
            }
        },
        context={'request': request}
    )

    if serializer.is_valid():

    serializer = WorkflowApprovalSerializer(
        instance=purchase_request,
        data={
            'action': 'APPROVED',
            # No form_data required for executive approval (as configured)
        },
        context={'request': request}
    )

    if serializer.is_valid():
        serializer.save()
        # ✅ WORKFLOW COMPLETED!
        # Status automatically changes to: "completed"

Step 6: Handle Rejections and Special Cases

# Reject workflow
def reject_budget_approval(request, purchase_request_id):
    purchase_request = PurchaseRequest.objects.get(id=purchase_request_id)

    serializer = WorkflowApprovalSerializer(
        instance=purchase_request,
        data={

        },
        context={'request': request}
    )

    if serializer.is_valid():
        serializer.save()
        # ❌ Workflow status becomes "rejected"

# Request resubmission to previous stage
def request_resubmission(request, purchase_request_id):
    purchase_request = PurchaseRequest.objects.get(id=purchase_request_id)

    # Get the initial review stage for resubmission
    finance_pipeline = purchase_request.workflow.pipelines.get(name_en='Finance Review')
    initial_review_stage = finance_pipeline.stages.get(order=1)

    serializer = WorkflowApprovalSerializer(
        instance=purchase_request,
        data={
            'action': 'NEEDS_RESUBMISSION',  # Use ApprovalStatus.NEEDS_RESUBMISSION
            'stage_id': initial_review_stage.id,  # Back to Initial Review
            'reason': 'Please provide additional cost breakdown details'
        },
        context={'request': request}
    )

    if serializer.is_valid():
        serializer.save()
        # ↩️ Goes back to specified stage

# Delegate to another user
def delegate_approval(request, purchase_request_id):
    purchase_request = PurchaseRequest.objects.get(id=purchase_request_id)

    serializer = WorkflowApprovalSerializer(
        instance=purchase_request,
        data={
            'action': 'DELEGATED',  # Use ApprovalStatus.DELEGATED
            'user_id': 123,  # Senior manager user ID
            'reason': 'Amount exceeds my approval limit'
        },
        context={'request': request}
    )

    if serializer.is_valid():
        serializer.save()
        # 👥 Approval responsibility transferred to user 123

Step 7: Track Progress

from django_workflow_engine.services import get_workflow_progress, get_workflow_attachment

def get_purchase_status(purchase_request_id):
    purchase_request = PurchaseRequest.objects.get(id=purchase_request_id)

    # Get workflow attachment and current stage info
    attachment = get_workflow_attachment(purchase_request)
    if not attachment:
        return {'error': 'No workflow attached to this purchase request'}

    # Get detailed progress using the attachment's workflow
    progress = get_workflow_progress(attachment.workflow, purchase_request)

    # Use helper function for current stage info
    stage_info = get_current_stage_info(purchase_request)

    return {
        'current_stage': stage_info['stage_name'] if stage_info else None,
        'current_pipeline': stage_info['pipeline_name'] if stage_info else None,
        'progress_percentage': progress['progress_percentage'],
        'status': progress['status'],
        'next_stage': attachment.next_stage.name_en if attachment.next_stage else 'Workflow Complete',
        'started_by': attachment.started_by.username if attachment.started_by else None,
        'started_at': attachment.started_at,
        'metadata': attachment.metadata,
        'workflow_name': attachment.workflow.name_en
    }

# Enhanced helper to check if user requires action
from approval_workflow.models import ApprovalInstance
from approval_workflow.choices import ApprovalStatus
from django.contrib.contenttypes.models import ContentType

def user_requires_action(purchase_request, user):
    """Check if user has pending approval for this purchase request"""
    content_type = ContentType.objects.get_for_model(PurchaseRequest)

    return ApprovalInstance.objects.filter(
        assigned_to=user,
        status=ApprovalStatus.CURRENT,
        flow__content_type=content_type,
        flow__object_id=str(purchase_request.id)
    ).exists()

# Example usage
def check_purchase_status_for_user(purchase_request_id, user):
    purchase_request = PurchaseRequest.objects.get(id=purchase_request_id)
    status = get_purchase_status(purchase_request_id)

    status['requires_user_action'] = user_requires_action(purchase_request, user)
    status['can_approve'] = user_requires_action(purchase_request, user)

    return status

API Integration Example

// Track workflow progress
const trackPurchaseWorkflow = async (purchaseId) => {
    const response = await fetch(`/api/purchase-requests/${purchaseId}/workflow_status/`);
    const status = await response.json();

    console.log(`Current Stage: ${status.current_stage}`);
    console.log(`Progress: ${status.progress_percentage}%`);
    console.log(`Status: ${status.status}`);
};

// Approve current stage
const approvePurchaseStage = async (purchaseId, formData) => {
    const response = await fetch(`/api/purchase-requests/${purchaseId}/workflow_action/`, {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({
            action: 'approved',
            form_data: formData
        })
    });

    if (response.ok) {
        trackPurchaseWorkflow(purchaseId);
    }
};

This example shows the complete journey from creating a purchase request to final approval, demonstrating how the workflow engine handles multi-pipeline, multi-stage processes with proper progression control.

get_workflow_pipeline_structure()

Get simplified pipeline structure for visualization.

from django_workflow_engine.services import get_workflow_pipeline_structure

structure = get_workflow_pipeline_structure(workflow_id=1)

get_workflow_approval_summary()

Get approval statistics and breakdown.

from django_workflow_engine.services import get_workflow_approval_summary

summary = get_workflow_approval_summary(workflow_id=1)
# Returns approval counts by type, strategy, and pipeline breakdown

get_workflow_statistics()

Get system-wide workflow statistics.

from django_workflow_engine.services import get_workflow_statistics

# All workflows
stats = get_workflow_statistics()

# Company-specific
stats = get_workflow_statistics(company_id=1)

Performance Features

• Optimized Queries: Uses select_related and prefetch_related for minimal database hits
• Smart Caching: Processes related data in memory to avoid N+1 queries
• Flexible Filtering: Company and active status filters with efficient query building
• Rich Metadata: Enriched approval configurations with human-readable displays

Usage Examples

Workflow Dashboard

def build_workflow_dashboard(company_id=None):
    """Build comprehensive workflow dashboard data"""
    # Get all workflows with statistics
    workflows_data = get_detailed_workflow_data(
        company_id=company_id,

        'total_count': workflows_data['total_count'],
        'statistics': workflows_data['statistics']
    }

Workflow Analysis

def analyze_workflow_complexity(workflow_id):
    """Analyze workflow complexity metrics"""
    # Get detailed data
    workflow = get_detailed_workflow_data(workflow_id=workflow_id)

    # Get approval breakdown

                })

    return {'nodes': nodes, 'edges': edges}

Performance Monitoring

def monitor_workflow_performance():
    """Monitor system-wide workflow performance"""
    stats = get_workflow_statistics()
    overview = stats['overview']

    return {
        'total_workflows': overview['total_workflows'],
        'active_percentage': (
            overview['active_workflows'] /

        'companies': len(stats['by_company']),
        'bottlenecks': [
            company for company, data in stats['by_company'].items()
            if data['approvals'] / data['stages'] > 2.0  # High approval ratio
        ]
    }

Configuration

The Django Workflow Engine can be configured through your Django settings:

# settings.py
DJANGO_WORKFLOW_ENGINE = {
    # Department Model Mapping (NEW)
    # Map the department GenericForeignKey to any model in your project
    'DEPARTMENT_MODEL': 'myapp.Department',  # Optional: specify your department model

    # Model Configuration
    'ENABLED_MODELS': [
        'myapp.PurchaseRequest',
        'crm.Opportunity',
        'support.Ticket',
    ],

    # Default field name for workflow status
    'DEFAULT_STATUS_FIELD': 'workflow_status',

    # Workflow Mappings
    'MODEL_WORKFLOW_MAPPINGS': {
        'myapp.PurchaseRequest': ['purchase_approval', 'emergency_approval'],
        'crm.Opportunity': ['sales_process'],
    },

    # Auto-start Configuration
    'AUTO_START_WORKFLOWS': {
        'myapp.PurchaseRequest': {
            'workflow_slug': 'purchase_approval',
            'conditions': {'amount__gte': 1000}  # Only for amounts >= 1000
        }
    },

    # Permissions
    'PERMISSIONS': {
        'REQUIRE_PERMISSION_TO_START': True,
        'REQUIRE_PERMISSION_TO_APPROVE': True,
    }
}

Department Model Configuration

The DEPARTMENT_MODEL setting allows you to map the department field in workflows to any model in your project:

# Map to your custom Department model
'DEPARTMENT_MODEL': 'myapp.Department'

# Map to Django's built-in Group model
'DEPARTMENT_MODEL': 'auth.Group'

# Map to any other model with a name field
'DEPARTMENT_MODEL': 'companies.Division'

This provides maximum flexibility for organizing workflows by departments, divisions, teams, or any organizational structure.
