django-exportable-admin 2.2

This app provides a ModelAdmin which you can subclass in order to allow your changelist view to be exported to CSV. This will add an “Export CSV” button to the top-right of the changelist. Clicking this button will export a CSV containing the same columns and headings as your changelist view. By default, up to 10,000 rows will be exported, though this can be changed easily.

Django > 1.3 is required, at which point the standard changelist_view() returns a TemplateResponse. This allows us to change the template used after the response is created, so that we can output CSV instead of the standard HTML view. Django <= 1.3 requires a previous version of this app in which the changelist_view code is duplicated and modified slightly to change the template and setup the response for download instead of display.

Note: if you alter ‘change_list_template’ on your ModelAdmin subclass, the “Export CSV” button will not appear. You will need to add it manually to your template or link to the correct url (admin:myapp_mymodel_export) by some other means.
