Usage

Add "crudbuilder" to INSTALLED_APPS

INSTALLED_APPS = {
        ...
        'django_tables2',
        'crudbuilder'
}

LOGIN_REQUIRED_FOR_CRUD = True/False
PERMISSION_REQUIRED_FOR_CRUD = True/False
PROJECT_NAME = 'YOUR PROJECT NAME'

Create models in yourapp/models.py

class Person(models.Model):
        """ an actual singular human being """
        name = models.CharField(blank=True, max_length=100)
        email = models.EmailField()
        created_at = models.DateTimeField(auto_now=True)
        created_by = models.ForeignKey(User, blank=True, null=True)

        def __unicode__(self):
                return self.name

Create CRUD for Person model in yourapp/crud.py

from crudbuilder.abstract import BaseCrudBuilder
from yourapp.models import Person

class PersonCrud(BaseCrudBuilder):
        model = Person
        search_fields = ['name']
        tables2_fields = ('name', 'email')
        tables2_css_class = "table table-bordered table-condensed"
        tables2_pagination = 20  # default is 10
        modelform_excludes = ['created_by', 'updated_by']
        login_required=True
        permission_required=True
        # permissions = {
        #   'list': 'example.person_list',
        #       'create': 'example.person_create'
        # }

Open yourapp/urls.py and add the following

from crudbuilder import urls

urlpatterns = [
        url(r'^admin/', include(admin.site.urls)),
        url(r'^crud/',  include(urls)),
]

View All your registered CRUDS

http://127.0.0.1:8000/crud/

Now you can access the below CRUD URLS

- http://127.0.0.1:8000/crud/yourappname/yourmodelname
- http://127.0.0.1:8000/crud/yourappname/yourmodelname/create/
- http://127.0.0.1:8000/crud/yourappname/yourmodelname/<pk>/detail/
- http://127.0.0.1:8000/crud/yourappname/yourmodelname/<pk>/update/
- http://127.0.0.1:8000/crud/yourappname/yourmodelname/<pk>/delete/

LOGIN REQUIRED

To enable global login required for all the models CRUD views, add the following to settings file

LOGIN_REQUIRED_FOR_CRUD = True

If you want to enable login required only for specific model crud, then you need to add following to crud class

# myapp/crud.py
login_required = True

PERMISSION REQUIRED

To enable global permission required for all the models CRUD views, add the following to settings file

PERMISSION_REQUIRED_FOR_CRUD = True

If you want to enable permission required only for specific model crud, then you need to add following to crud class

# myapp/crud.py
permission_required = True

By enabling either of above flag, crudbuilder by default checks for following permissions:

- For ListView   : <your app_name>.<your model>_list
- For CreateView : <your app_name>.<your model>_create
- For DetailView : <your app_name>.<your model>_detail
- For UpdateView : <your app_name>.<your model>_update
- For DeleteView : <your app_name>.<your model>_delete

If you want to add your own permissions, then define your own permission required dictionary explicitly in CRUD class.

permissions = {
        'list'  : 'example.permission1',
        'create': 'example.permission2'
        'detail': 'example.permission3',
        'update': 'example.permission4',
        'delete': 'example.permission5',
        }

EXTRA TEMPLATE VARIABLES

Added mixin which allows access to additional template variables like app lable and model name in every template.

APP : {{app_label}}
MODEL : {{actual_model_name}}
PLURIZED MODEL : {{pluralized_model_name}}
