Map.resources and extensions

Ruby Apps Radiant CMS
1

Hi list,

I am tracking radiant svn and am setting up a new extension following
the tutorial.

I have the extension loading up and am using scaffold generated by rails
2.

The problem i am having is that i get a lot of

undefined method `project_path’ for #ActionView::Base:0x34205ec
errors.

Not being very good at routing i was hoping someone could help.

in my routes i have

define_routes do |map|

 map.namespace(:admin) do |admin|
    admin.resources :projects
 end

end

rake routes shows they are set up correctly, but if i include something
like (this is stock rails scaffold)

<%=h project.name %> <%=h project.mailing_list %> <%= link_to 'Show', project %> <%= link_to 'Edit', edit_project_path(project) %> <%= link_to 'Destroy', project, :confirm => 'Are you sure?', :method => :delete %>

It gives me the above error.

Anyone have an idea? does map.resources work with extensions or am i
going to have to wright named routes instead?

Thanks

Hi Mark,

I’m a newbie too, but I think I might be able to help a bit. In the
book, “Rails 2: New features for you applications”, Ryan Daigle writes
about namespaces:

Namespaces

You can now declare a routing namespace using in a RESTful manner
with map.namespace. The most common use of this is for establishing
an administrative section of an application.

map.namespace(:admin) do |admin|
admin.resources :posts
end

With this routing definition, you get the standard host of post routes
and URL helpers, all prefixed with admin:

  • admin_posts – /admin/posts
  • admin_post(post) – /admin/posts/:id
  • formatted_admin_post(post, format) – /admin/posts/:id.:format
  • new_admin_post – /admin/posts/new
  • edit_admin_post(post) – /admin/posts/:id/edit
  • etc.

With this namespace, the routing mechanism will try to find a controller
named Admin::PostsController to satisfy these URLs.

So, the admin namespace mapping doesn’t generate URL helpers for
products without including “admin” somewhere.

I think edit_project_path(project) should be
edit_admin_project_path(post).

But like I said, I’m still just getting the hang of Rails so don’t quote
me on that. Maybe one the more experienced guys here can help further.

Hi Mark,

map.resources definitely works in extensions. Here is an example from
one of my private extensions:

define_routes do |map|
map.reorder_materials ‘/admin/materials/reorder’, :controller =>
‘admin/materials’, :action => ‘reorder’
map.resources :materials do |material|
material.resources :branded_materials
end
map.resources :materials, :path_prefix => ‘/admin’, :name_prefix
=> ‘admin_’, :controller => ‘admin/materials’
map.home ‘’, :controller => ‘materials’, :action => ‘index’
map.admin ‘/admin’, :controller => ‘admin/materials’, :action =>
‘index’
end

I’m not completely sure how map.namespace works, having never used it
myself, but I’d guess you’d need to prefix your url-generation calls
with “admin_” having put the resource in the admin namespace. So in
your case, it should be something like this (untested):

edit_admin_project_path

Good luck!

Whoops, I forgot to completely edit that.

I meant to say, “I think edit_project_path(project) should be
edit_admin_project_path(project).”

Also, the book is “Rails 2: New features for your applications”. I
forgot the ‘r’ on “your” in my previous post.

Thanks,

adding map.resources :projects, :path_prefix => ‘/admin’, :controller
=> ‘admin/projects’ seems to have done the trick.
