    <p>so I'm trying to build a sign-up process just like <a href="http://www.twitter.com" rel="nofollow">Twitter</a> has. Meaning, there's a pre-sign up form which leads to full form with autopopulated fields from the first form. I'm trying to create this using <code>:value =&gt; @name</code> in the final form, but it's not working and I just can't figure out why.</p> <p>Here's my code, simplified:</p> <p><strong>First form, controller: public_controller, action: index (root_path)</strong></p> <pre><code>&lt;%= form_tag({:controller =&gt; "users", :action =&gt; "register"})%&gt; &lt;input name="user[name]" type="text" /&gt; &lt;input name="user[email]" type="text"/&gt; &lt;input name="user[password]" type="password"/&gt; &lt;input name="commit" type="submit" value="Sign Up!" /&gt; </code></pre> <p><strong>Second form, controller: users_controller, action: register (/signup)</strong></p> <pre><code> &lt;%= form_for(:user, :url =&gt; { :controller =&gt; 'users', :action =&gt; 'create' }) do |f| %&gt; &lt;%= f.text_field :name, :value =&gt; @name %&gt; &lt;%= f.text_field :email, :value =&gt; @email %&gt; &lt;%= f.password_field :password, :value =&gt; @password %&gt; &lt;input name="commit" type="submit" value="Sign Up!" /&gt; &lt;% end %&gt; </code></pre> <p><strong>Users_controller</strong></p> <pre><code>def register @name = params[:name] @email = params[:email] @password = params[:password] end </code></pre> <p><strong>The params are passing to the final form page (/signup)</strong></p> <p>{"utf8"=>"✓", "authenticity_token"=>"R3wVNHvqpDBi1Lg69lwKu4NeQGjA12oV/Aytw38OeHc=", "user"=>{"name"=>"Stackoverflow", "email"=>"stack@stackstack.com", "password"=>"stacker", "password_confirmation"=>"stacker"}, "commit"=>"Sign Up!", "search"=>"", "controller"=>"users", "action"=>"register"}</p> <p>But they are not autopopulating the final form's fields.</p> <p>I've also tried using <code>:input_html =&gt; { :value =&gt; @name }</code> with <code>params[:name]</code>, but it has no effect, and the input's value simply turns to value="nil".</p> <p>I just can't think of anything else to try from here. Any ideas? Thanks in advance! Any help is greatly appreciated!</p>

    1. COIt should be working, have you checked the `params` hash in your `register` action?

    2. COYeah, it was okay. I finally actually got it working by thrashing the variables from `register` action and just going `:value => params[:user][:name] and params[:user][:email]` on the final form. No idea why it didn't work the other way around, but I guess this does the same job. Thanks a lot for looking at it, though.

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.
