Installation
------------

``pip install django-crudbuilder``

Usage
-----

1. Add "crudbuilder" to INSTALLED_APPS:

.. code-block:: python

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

LOGIN_REQUIRED_FOR_CRUD = True/False
PERMISSION_REQUIRED_FOR_CRUD = True/False


2. Create models in yourapp/models.py

.. code-block:: python

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

3. Create CRUD for Person model in yourapp/crud.py

.. code-block:: python
from crudbuilder.abstract import BaseCrudBuilder
from yourapp.models import Person

class PersonCrud(BaseCrudBuilder):
model = Person
search_feilds = ['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']
# permission_required = {
# 'list': 'example.person_list',
# 'create': 'example.person_create'
# }


4. Open yourapp/urls.py and add the following
```
urlpatterns = [
url(r'^admin/', include(admin.site.urls)),
url(r'^crud/', include('crudbuilder.urls')),
]
```

5. 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 login required for all CRUD views, add the following to settings file

``` LOGIN_REQUIRED_FOR_CRUD = True```


PERMISSION REQUIRED
-------------------
To enable permission required for all CRUD views, add the following to settings file

``` PERMISSION_REQUIRED_FOR_CRUD = True```

By enabling the 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 exlicitly in CRUD class.
```
permission_required = {
'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}}
```

EXTENDABLE
----------
All the generated views/tables/forms/url are extendable.

```
# GENERATE CRUD CLASSES
------------------------
from crudbuilder.views import ViewBuilder
builder = ViewBuilder('example', 'person', crudclass)
builder.generate_crud()
builder.classes

{'PersonCreateView': <class 'django.views.generic.edit.PersonCreateView'>,
'PersonDeleteView': <class 'crudbuilder.views.PersonDeleteView'>,
'PersonListView': <class 'crudbuilder.views.PersonListView'>,
'PersonUpdateView': <class 'django.views.generic.edit.PersonUpdateView'>,
'PersonDetailView': <class 'crudbuilder.views.PersonDetailView'>
}

# OVERRIDE AUTO GENERATED VIEWS
------------------------------
from crudbuilder.views import ViewBuilder
builder = ViewBuilder('example', 'person')
builder.generate_crud()
PersonListView = builder.classes['PersonListView']
class CustomPersonListView(PersonListView):
def get_context_data(self, **kwargs):
context = super(CustomPersonListView, self).get_context_data(**kwargs)
context['your_template_variable'] = 'Your new template variable'
return context

# OVERRIDE AUTO GENERATED TABLE (from django_tables2)
-----------------------------------------------------
from crudbuilder.tables import TableBuilder
builder = TableBuilder('example', 'person')
PersonTable = builder.generate_table()
class CustomPersonTable(PersonTable):
# add your custom implementation here
```
