|
Test that we can update an OAuth provider's icon image from the admin
|
|
form.
|
|
|
|
OAuth providers are updated using KeyedConfigurationModelAdmin, which
|
|
updates models by adding a new instance that replaces the old one,
|
|
instead of editing the old instance directly.
|
|
|
|
Updating the icon image is tricky here because
|
|
KeyedConfigurationModelAdmin copies data over from the previous
|
|
version by injecting its attributes into request.GET, but the icon
|
|
ends up in request.FILES. We need to ensure that the value is
|
|
prepopulated correctly, and that we can clear and update the image.
