Signals (example)

def database_user_delete(sender, instance, **kwargs):
    if settings.ENABLE_ARCHITECTURE_OPERATIONS:
        alwaysdata.common.scripts.database.delete_user(instance)

pre_delete.connect(database_user_delete, sender=DatabaseUser)
        

Custom CRUD library (simple example)

class FtpUserCrud(django_crud.ModelCrud):

    model = FtpUser
    form_class = FtpUserForm
    operations = 'CRUDL'
    url_prefix = 'ftp'
    decorators = [permission_required('account_ftp')]

    def get_success_url(self):
        return reverse('domain_read', args=(self.domain.id,))

    def get_created_message(self):
        return mark_safe(_(u"L'utilisateur FTP %s a été créé.") % self.object.name)

django_crud.handler.TemplateHandler.register(FtpUserCrud)
        

get_object(), get_queryset(), get_context_data(), get_form(), get_form_kwargs() and more...

Custom CRUD library (api example)

class ApiModelCrud(django_crud.handler.api.ApiModelCrud):

    excludes = set(('password',))
    url_prefix = 'v1/'

class DatabaseCrud(ApiModelCrud):

    model = Database
    form_class = DatabaseForm
    operations = 'RUL'
    decorators = [permission_required('account_database')]
    url_prefix = ApiModelCrud.url_prefix + 'database'
    excludes = ApiModelCrud.excludes | set(('account', ))
    container_fields = ['options',]

django_crud.handler.ApiHandler.register(DatabaseCrud)
