wizard related error

[joshyu]

As @fsbraun removed the get_absolute_url via this PR ( #199), and our new alias entry is in the wizard creation. so we will get some errors when we create new alias and alias category via wizard button.

This is related to below function call in wizard_base.py fil in django cms

I think we need to fix that.

@fsbraun ,
please provide your input.

@joshyu Well spotted!

Indeed, the default wizard assumes the model created has a get_absolute_url method, AliasCategory does not since it does not offer a URL to the user space.

We need to overwrite get_success_url in the alias category wizard. It needs to return the category's get_admin_change_url. Would you like to make a PR?

@fsbraun,
How to override the get_success_url in the alias? Do you have any reference for me?
sorry I didn't work on this part before. I need a sample, you can tell me to check which addon.

[fsbraun]

Just add a method to this:

djangocms-alias/djangocms_alias/cms_wizards.py

Lines 17 to 21 in 3dfa143

	class CreateAliasCategoryWizard(Wizard):
	def user_has_add_permission(self, user, **kwargs):
	return user.has_perm(
	get_model_permission_codename(Category, "add"),
	)

Something like:

def get_success_url(self, obj, **kwargs):
    return obj.get_admin_change_url()
