Description

Several times you "hack" the admin interface and want to use extra GET parameters.

Look at this example:

class FooModelAdmin(admin.ModelAdmin):
     # ...
     def get_list_display(self, request, extra_context=None):
         if request.GET.has_key('hide_columns'):
             return ('pk', )
         return super(FooModelAdmin, self).get_list_display(request, extra_context)

But this is impossible because the "hide_columns" GET parameter is not allowed by security reasons. The allowed parameters (IGNORED_PARAMS global variable) is hardcoded (look at [source:django/trunk/django/contrib/admin/views/main.py#L29 this code]).

Should be good if you should configure this parameters. I don't know if a new setting should be good or maybe a ChangeList.get_ignored_lookup_params() method to do something like that:

class FooChangeList(ChangeList):

    def get_ignored_lookup_params(self):
         return super(FooChangeList, self).get_ignored_lookup_params() +  ['hide_columns']

Of course you can extends the ChangeList and override the ChangeList.get_lookup_params() method but should be better of using a special method for this useful thing.

The little patch in django.contrib.admin.views.main module would be something like that:

                 ordering_fields[idx] = 'desc' if pfx == '-' else 'asc'
         return ordering_fields
 
+    def get_ignored_lookup_params(self):
+        return IGNORED_PARAMS
+
     def get_lookup_params(self, use_distinct=False):
         lookup_params = self.params.copy() # a dictionary of the query string
 
-        for ignored in IGNORED_PARAMS:
+        for ignored in self.get_ignored_lookup_params():
             if ignored in lookup_params:
                 del lookup_params[ignored]

Has patch: set

I attached a patch with corrections to the docs for language and for clarity. However, I wonder if this is really the solution? Really, shouldn't lookup_params that aren't fields on the model always be ignored? They certainly aren't security risks the same way as other items. get_ignored_lookup_params should only be necessary if (for some reason) there's a conflict between the name of the param you want to handle and one of the fields on the model.

It's been 12 years since the ticket was opened. As far as I'm aware, this is rather niche and monkey patching a module constant is an acceptable approach for the reported issue. It's not worth adding extra hooks.
