Problem:
I have added several @actions to my ModelAdmin (for model Post), then I added @link to integrate with django-import-export as described in Readme.md. When I follow "Export" link I get to export page successfully, but when I try to export in any format, I get error:
IncorrectLookupParameters at /admin/posts/post/_export/
Post has no field named '_changelist_filters'
import-export uses request to filter queryset as it was filtered in changelist, but extra-urls save all filters in single query parameter _changelist_filters
when building @link href. I found easy workaround, though it may be should be in docs:
from django.http.request import QueryDict
...
@link(label='Export')
def _export(self, request):
if '_changelist_filters' in request.GET:
real_query = QueryDict(request.GET.get('_changelist_filters'))
request.GET = real_query
return self.export_action(request)
When adding ExtraUrlMixin to a ModelAdmin the django out-of-the-box "Add " option lose its "addlink" css class. The result is that no "+" sign (tooltag-add.svg) appears in that option.
@admin.register(models.Plan)
class PlanAdmin(ExtraUrlMixin, admin.ModelAdmin):
@link(label='Recurly Sync') # /admin/myapp/mymodel/update_all/
def rsync(self, request):
try:
models.Plan.rsync(False)
self.message_user(request, "All synced!")
except RuntimeError as e:
self.message_user(request, "Sync failed: {}".format(e), level=messages.ERROR)
I have a model that has redefined the objects key as something else, and it breaks on the _inner
wrapper inside the button decorator as it specifically calls modeladmin.model.objects.get
when it should use modeladmin.get_object

It would be good to add a "target" parameter for opening a new page
