    <p>Is there any method that i should look at in rails3.2 source code so as to know where the navigation or the url part of the render call get resolved? The reason is, i have a small app in which url is of the form </p> <blockquote> <p>www.example.com/bob/edit</p> </blockquote> <p>the above route as it suggests renders the edit form.EDIT: i was able to get to this route by modifying response on the link_to helper.</p> <pre><code>def update #when validation passes redirect_to @user #when validation fails respond_to do |format| format.html {render :action =&gt; "edit"} end end </code></pre> <p>Now the problem is when a validation error occurs on submission to update action of users_controller, the url becomes </p> <blockquote> <p>www.example.com/users/bob/edit</p> </blockquote> <p>config/routes.rb</p> <pre><code>get "users/new", to: =&gt; "users#new" resources :users </code></pre> <p>as you can see there's nothing interesting happening in routes, </p> <p>in models/user.rb</p> <pre><code>def to_param "#{name}" end </code></pre> <p>in views/edit.html.erb</p> <pre><code>form_for(@user) do |f| end </code></pre> <blockquote> <p><strong>Observation:</strong> here when the form is rendered afresh, form 'action' points to "users/bob" but when the form is re-rendered 'cos of validation error, form action mysteriosly changes to "users/" which is weired and if i remove the to_param in user.rb model it works fine </p> </blockquote> <p>Though its not such a big deal, i was thinking where, if i needed to override the url that is generated on render call, to change?????</p> <p>Any suggestions and pointers to explore are wecome....</p>

    1. COI guess the secound url example should be: `www.example.com/users/bob` -- you showed the same url twice.

    3. COSeems that your form is actually putting the update to the second URL. Are you using resourceful routes ? If so is it a singular resource or a plural one ?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
