Django Admin Detail View

Django Admin's missing DetailView.

Allows easy creation of a DetailView via DSL for an object in Django Admin.

Why this exists

Django Admin's is missing detail views (by design). It's strengths lie in administering specific objects via form modification.

But, a common need is to allow internal staff/admins to view specific objects and and their related objects. Historically the recommendation was to build a separate website/frontend for this.

Theory

With models Company, ContactInfo, SalesLeads, Orders, Internal staff want to quickly understand the status of a particular Company so a simple View displaying these 4 objects is very beneficial.

Then I can drill down into a Order and see all related Products, OrderStatusUpdates, SalesComments.

Via DSL, it is fast to stand up DetailViews for many objects.

Beliefs

Information dense, grid layout. Function over form.

Features

• Add View button to changelist for Object.
• detail_table_for() builds object's details table.
• table_for() builds a list of
• ctx["layout"] holds the grid structure.

Pre-reqs

• Bootstrap as Webpack
• webpack_loader

Install

1. Direct add github to pyproject.toml, [e-mail]:jenfi-eng/djadmin-detail-view.git.
2. Add to INSTALLED_APPS
3. Create a DetailView and add mixin AdminDetailMixin
4. To the object's admin add AdminChangeListViewDetail and function get_default_detail_view
5. Return the newly created DetailView in get_default_detail_view.

See example_project/companies/admin.py for reference.

Code Example

from django.contrib import admin
from djadmin_detail_view.views import AdminChangeListViewDetail, AdminDetailMixin

from my_app.companies.models import Company

@admin.register(Company)
class CompanyAdmin(AdminChangeListViewDetail, admin.ModelAdmin):
    def get_default_detail_view(self):
        return CompanyDetailView

class CompanyDetailView(AdminDetailMixin, DetailView):
    model = Company

    def get_context_data(self, request, *args, **kwargs):
        ctx = super().get_context_data(request, *args, **kwargs)

        company_details = details_table_for(
            panel_name="Company Details",
            obj=self.object,
            details=[
                detail("id"),
                detail("legal_name"),
                detail("tax_id"),
                detail("total_completed_order_amount", value=lambda x: x.total_order_value()),
            ]
        )

        orders_list = table_for(
            panel_name="Orders",
            obj_set=self.object.order_set.all(),
            cols=[
                col("id"),
                col("legal_name"),
                col("total_value"),
                col("created"),
            ]
        )

        ctx["layout"] = [
            {
                "row": [
                    {"col": company_details},
                    {"col": None},
                ],
            },
        ]

Current Open Source Status

This project is not ready for wider consumption. It is currently built for Jenfi and its internal needs. Thus, it has specific requirements such as django-hosts that may need to be abstracted away.

PRs are welcome to make it more generally accessible.

VSCode

Testing

Add config to allow specs to be run inside VSCode.

// .vscode/settings.json
{
  "python.testing.pytestArgs": [
    ""
  ],
  "python.testing.unittestEnabled": false,
  "python.testing.pytestEnabled": true,
}

Web Launch Config

{
    "name": "Django Web",

    "request": "launch",
    "program": "${workspaceFolder}/server.py",
    "args": [],
    "django": true,
    "justMyCode": false
},

TODO

1. Add specs.
2. Versioning and release on pypi.
3. Allow non-webpack based installs.
