Ralph Admin¶
Ralph Admin class (ralph.admin.mixins.RalphAdmin
) is built on top of regular Django Admin and has bunch of extending features. Some of them are listed below.
Import-Export¶
Ralph Admin has built-in support for importing and exporting objects (using django-import-export). Possible configuration:
Resource class¶
Define resouce_class
in your Admin to specify django-import-export's resource class used to handle importing and exporting of this model.
Example:
class SupportAdmin(RalphAdmin):
...
resource_class = resources.SupportResource
...
Export queryset¶
Define _export_queryset_manager
attribute in your Admin to specify which manager will be used to handle export queries. This should be string with model's attribute name for proper manager.
Example:
class SupportAdmin(RalphAdmin):
...
_export_queryset_manager = 'objects_with_related'
...
Export in Admin by default use
get_queryset
from Django's admin to properly handle all filters etc. During export from Admin,get_queryset
defined in your Resource is not used, but it is a good practice, to point them to the same objects manager.
Fetching related objects¶
Ralph Admin, by default, select and prefetch all related objects that are defined in Resource's Meta.
