admin_url with view permission

[covadonga99]

Hello!
Why you need change permissions to click in the changelist view of a model? I have a model user in the core app and I have a group with add and view permissions to this model but not change permissions and this group can't access to this view from the side menu but it can access to the changelist view if it clicks in the core app from the side menu it can click on the view of the users (or entering with the url). This is because of this piece of code:
```
if perms.get('change', False):
try:
model_dict['admin_url'] = reverse('admin:%s_%s_changelist' % info, current_app=admin_site.name)
except NoReverseMatch:
pass

Doesn't this perms.get("change", False) should be perms.get("view", False)?

You can create a subclass of ModelAdmin and override the has_change_permission method to check for the 'view' permission instead. Here's an example:

from django.contrib import admin

class CustomModelAdmin(admin.ModelAdmin):
def has_change_permission(self, request, obj=None):
opts = self.opts
codename = get_permission_codename('view', opts)
return request.user.has_perm('%s.%s' % (opts.app_label, codename))

Then, register your model using the CustomModelAdmin instead of the default admin.ModelAdmin.

from django.contrib import admin
from myapp.models import MyModel

admin.site.register(MyModel, CustomModelAdmin)
With this customization, users who have the 'view' permission for the model will be able to access the change list view in the admin side menu
