allowed? helper throwing error

[crtr0]

When I try to use the allowed? helper in my show.html.erb file, I get this error:

uninitialized constant Edit

The url being protected is a nested resource edit url = /seasons/1/edit

I am using the 3.0.0 gem, and Rails 2.3.4

[mdarby]

Can you please post the code? Also, by the URL it looks as though you're trying to edit a non-nested resource (or at least a parent resource).

[crtr0]

You're right, the edit isn't nested (new and index are).

Here's the code in my view:

<%= allowed? { link_to 'Edit', edit_season_path(@season) } %>

...where edit_season_path(@season) resolves to /seasons/:id/edit

[mdarby]

Odd... everything seems alright... Can you post the stack trace?

Here's a line in the url_parser.rb that I have:

{:name => "edit_singleton_child",       :controller_bit => 3, :object_id_bit => nil, :regex => /\/(\w+)\/(\d+)[\w|-]*\/(\w+)\/edit$/},

...which I think is slightly different than what I see in the trunk (I think). Could that be it?

[mdarby]

:edit_singleton_child shouldn't be firing in this case. What does your logical_parent line look like on season.rb?

[crtr0]

logical_parent :division

I'll confess, I haven't grokked what the point of that declaration is.

[mdarby]

Ahh. It looks like Season doesn't have a 'parent' at all (at least judging by the URL). Try commenting out the logical_parent statement (since it doesn't have one) and see what happens. The important part is the 'before_filter :has_permission?' in the controller.

[crtr0]

No dice. I commented it out, but it still errors out. Season does belong_to Division. Are you sure this isn't an issue of parsing the URL and instantiating the class? It's clearly trying to instantiate an "Edit" class (which makes me think it's mis-parsing the path).

[mdarby]

Season may belong to Division, but the routes need to be namespaced.

map.resources :division do |d| d.resources :seasons end

[mdarby]

Sorry - nested, not namespaced.

[crtr0]

This is what I currently have:

map.resources :divisions, :has_many => :seasons

[mdarby]

Try using the full nested url in the allowed? block edit_division_season_path(@division, @season)

[crtr0]

Huzzah! It works :)

But, I'm confused.

1) I still have the logical_parent declaration commented out. What's it for?

2) What if I don't want to use the fully nested URL for certain actions (like update, edit, show, etc)?

[mdarby]

1. The logical_parent statement just tells RESTful_ACL what you consider the parent of that object to be. You use it in the 'child' to point towards the 'parent'.
2. It won't work ;)

I'll update the docs to make the required use of nested routes more evident.

[crtr0]

I understand the semantic meaning of the declaration, but how is it used in the code? How come I can comment it out and things still work properly?

And do you think there is any simple way for me to use restful_acl without nested resources? It's a great plug-in, but I still want to be able to protect top-level resources.
