🚀 django_resaas
django_resaas é um framework modular para construção de aplicações SaaS multi-tenant em Django, com:
- 🔐 Controle de permissões (RBAC)
- 🏢 Multi-tenant (Entity / Branch)
- 🧩 Módulos ativáveis por cliente
- 💰 Billing por plano (SaaS ready)
- ♻️ Soft delete + restore
- 🔎 Busca dinâmica automática
- ⚡ BaseAPIView inteligente (DRF)
🧠 Arquitetura
User
↓
Person
↓
Employee (RH)
↓
Entity (tenant)
↓
Branch
↓
Groups + Permissões
🧩 Conceitos principais
🏢 Entity (Tenant)
Representa o cliente (empresa)
🏬 Branch
Unidade da entity
👤 Person
Dados humanos (name, email, etc.)
🔐 User
Autenticação
👥 BranchUserGroup
Relaciona:
- User
- Branch
- Group (Django)
👉 Permite múltiplos groups por branch
🔐 Sistema de Permissões (RBAC)
Baseado em:
User + Group + Permission (Django)
+ contexto (Entity + Branch)
Headers obrigatórios:
ET → entity_type
E → entity
S → branch
G → group
L → language
🧱 BaseModel
Todos os models herdam:
from django_resaas import BaseModel
Inclui:
- entity
- branch
- created_at / updated_at
- soft delete
- created_by / updated_by
🔁 Soft Delete
obj.delete() # soft delete
obj.restore() # restore
obj.hard_delete() # delete real
Managers disponíveis:
Model.objects # ativos
Model.deleted_objects # apagados
Model.all_objects # todos
⚡ BaseAPIView
CRUD automático com:
- multi-tenant automático
- permissões automáticas
- search dinâmica
- soft delete
- restore
- hard delete
Uso:
from django_resaas import BaseAPIView, register_view
@register_view(module="hr")
class EmployeeView(BaseAPIView):
queryset = Employee.objects.all()
serializer_class = EmployeeSerializer
🔍 Busca dinâmica
GET /api/employees/?search=joao
Busca automaticamente em:
- name
- código
- relações (FK)
🧩 Sistema de Módulos
Permite ativar/desativar funcionalidades por cliente.
Models:
- App
- EntityApp
Exemplo:
| Entity | Módulo | Estado |
|---|---|---|
| Empresa A | RH | ✅ |
| Empresa A | CRM | ❌ |
🔐 Proteção automática por módulo
@register_view(module="hr")
class EmployeeView(BaseAPIView):
...
👉 Se módulo não estiver ativo → acesso bloqueado
💰 Billing (SaaS)
Models:
- Plano
- PlanoApp
- EntityPlano
Fluxo:
Plano → módulos → EntityPlano → ativa módulos automaticamente
🔄 Sync automático de módulos
Ao mudar plano:
sync_apps_entity(entity)
📦 BaseSerializer
Proteção automática de arquivos:
{
"file": {
"url": "...",
"name": "...",
"ext": "pdf",
"size": 12345
}
}
🌐 Middleware
TenantContextMiddleware
Captura headers:
request.entity_id
request.branch_id
request.group_id
FrontEndMiddleware
Protege acesso por:
- chave frontend (FEK/FEP)
- permissões por URL
- permissões por método HTTP
🧪 Exemplo completo
Model
from django_resaas import BaseModel
class Employee(BaseModel):
person = models.ForeignKey('django_resaas.Person', on_delete=models.CASCADE)
cargo = models.CharField(max_length=100)
Serializer
from django_resaas import BaseSerializer
class EmployeeSerializer(BaseSerializer):
class Meta:
model = Employee
fields = "__all__"
View
from django_resaas import BaseAPIView, register_view
@register_view(module="hr")
class EmployeeView(BaseAPIView):
queryset = Employee.objects.all()
serializer_class = EmployeeSerializer
