Usage

Custom Admin Enhancements

BaseModelAdmin

The BaseModelAdmin class provides a set of default configurations for Django admin models, including custom widgets for text and file fields.

from ez_django_common.admin import BaseModelAdmin
from django.contrib import admin
from .models import MyModel

@admin.register(MyModel)
class MyModelAdmin(BaseModelAdmin):
    list_display = ('name', 'created_at')

Custom Inlines

The package provides custom inline classes (TabularInline, StackedInline, NonrelatedTabularInline, NonrelatedStackedInline) that can be used to organize inline models in the admin interface.

from ez_django_common.admin import TabularInline
from django.contrib import admin
from .models import MyModel, RelatedModel

class RelatedModelInline(TabularInline):
    model = RelatedModel

@admin.register(MyModel)
class MyModelAdmin(BaseModelAdmin):
    inlines = [RelatedModelInline]

Unfold

To use unfold for panel admin, first add unfold to INSTALLED_APPS:

INSTALLED_APPS = [
    'unfold', # before django.admin.contrib
    ...
]

then use BaseModelAdmin instead of admin.ModelAdmin in admin classes:

from ez_django_common.admin import BaseModelAdmin

@admin.register(ModelName)
class ModelNameAdmin(BaseModelAdmin):
    ...

Custom Responses

The enveloper function wraps your serializers in a standardized response format, including fields for data, error, and message.

from ez_django_common.custom_responses.enveloper import enveloper

@extend_schema(
    responses=enveloper(SampleRetrieveSerializer, many=False),
)
def retrieve(self, request, *args, **kwargs):
    return super().retrieve(request, *args, **kwargs)

Or if your response is a list of objects:

from ez_django_common.custom_responses.enveloper import enveloper_pagination

@extend_schema(
    ...
    responses=enveloper_pagination(SampleRetrieveSerializer, many=True),
)
def list(self, request, *args, **kwargs):
    return super().list(request, *args, **kwargs)

Custom Exception Handler

The custom_exception_handler provides a standardized way to handle exceptions in your Django REST Framework views.

REST_FRAMEWORK = {
    ...
    "EXCEPTION_HANDLER": "ez_django_common.custom_responses.exception.custom_exception_handler",
    ...
}

JWT Utilities

• CustomTokenViewBase

The CustomTokenViewBase class provides a base for custom JWT token views, including token refresh and verification.

from ez_django_common.custom_responses.jwt import CustomTokenRefreshView, CustomTokenVerifyView
from rest_framework_simplejwt.views import TokenRefreshView, TokenVerifyView

urlpatterns = [
    path('token/refresh/', CustomTokenRefreshView.as_view(), name='token_refresh'),
    path('token/verify/', CustomTokenVerifyView.as_view(), name='token_verify'),
]

Model Mixins

The package includes several mixins for common CRUD operations in Django viewsets.

from ez_django_common.custom_responses.viewsets import CustomModelViewSet
from .models import MyModel
from .serializers import MySerializer

class MyModelViewSet(CustomModelViewSet):
    queryset = MyModel.objects.all()
    serializer_class = MySerializer

Permissions

• CustomDjangoModelPermissions

The CustomDjangoModelPermissions class extends Django's default model permissions, allowing you to add additional permissions.

from ez_django_common.permissions import get_custom_model_permissions
from rest_framework.permissions import IsAuthenticated

permission_classes = [IsAuthenticated, get_custom_model_permissions(['myapp.view_mymodel'])]

Utilities

• Upload_to

The upload_to function provides a standardized way to handle file uploads in Django models.

from ez_django_common.storages import upload_to
from django.db import models

def upload_to_path(instance, filename):
    return upload_to(instance, filename, folder="path")

class MyModel(models.Model):
    file = models.FileField(upload_to=upload_to_path)
