Question

To become member, A user can use a button to create a membership on the community page. This is made on a partial that create a new “membership”
the memberships_controller :

 @community = Community.find(params[:community_id])
 @community.memberships.create(:user => current_user, :role => 1)

in The view :

<% form_remote_tag :url => community_memberships_path(@community) do %>
   <%= submit_tag 'Join' %>
<% end %>

After upgrading to Rails 3, that doesn’t work anymore !

I tried this :

<% form_tag( {:url => community_memberships_path(@community)}, :remote => true) do %>

and this :

<% form_tag :url => {:controller => '/memberships/new', :action => :create,:community_id => @community }, :remote => true do %>

But no chance.. and have this error

No route matches “/communities/2

Thx for help

Answer 1

The URL is the first argument, options are secondary.

<% form_tag(community_memberships_path(@community), :remote => true) do %>
   ...

As for your No route matches exception, check you have translated you routes to the Rails 3 syntax correctly.
