    <p>I am working on the front-end part of a Rails 3.1 application. We are using a Twitter Bootstrap as CSS Framework, Devise as the authentication manager and the I18n gem for localization.</p> <p>This is the devise syntax for a checkbox with its label</p> <pre><code>&lt;%= f.label :remember_me %&gt; &lt;%= f.check_box :remember_me %&gt; </code></pre> <p>And this of course is the generated HTML</p> <pre><code>&lt;label for="user_remember_me"&gt;Ricordati di me&lt;/label&gt; &lt;input name="user[remember_me]" type="hidden" value="0"&gt; &lt;input id="user_remember_me" name="user[remember_me]" type="checkbox" value="1"&gt; </code></pre> <p>Since Bootstrap adds this rule for the labels <code>display: block</code>, the label and the checkbox are not in the same line. To have the on the same line I need an HTML output like this</p> <pre><code>&lt;label for="user_remember_me"&gt; Ricordati di me &lt;input name="user[remember_me]" type="hidden" value="0"&gt; &lt;input id="user_remember_me" name="user[remember_me]" type="checkbox" value="1"&gt; &lt;/label&gt; </code></pre> <p>As shown in the <a href="http://twitter.github.com/bootstrap/base-css.html#forms" rel="nofollow">forms markup documentation</a></p> <p>You will have noticed that the label text is in Italian, the team member who provided localization for Devised worked hard to find out how to do so, and I do not want to force he to work on it again introducing new localized strings.</p> <p>I am aware of the nice fact that the <code>FormBuidler</code> <code>label</code> method accepts a block as an argument so I could do</p> <pre><code>&lt;% f.label :remeber_me do %&gt; &lt;%= f.check_box :remember_me %&gt; &lt;% end %&gt; </code></pre> <p>But this produce an HTML output <b>whitout</b> the label! o.O To be specific this is what I get:</p> <pre><code>&lt;input name="user[remember_me]" type="hidden" value="0"&gt; &lt;input id="user_remember_me" name="user[remember_me]" type="checkbox" value="1"&gt; </code></pre> <p>I tried to look in the source code, the <a href="https://github.com/rails/rails/blob/defb751681640e11f2187439acdaaa12ca9b805f/actionpack/lib/action_view/helpers/form_helper.rb#L1313" rel="nofollow"><code>f.label</code> method</a> calls the <a href="https://github.com/rails/rails/blob/defb751681640e11f2187439acdaaa12ca9b805f/actionpack/lib/action_view/helpers/form_helper.rb#L658" rel="nofollow"><code>label</code> method</a>, but I can only see that if there is a block no text will be printed and that the label and block will be rendered by the <code>label_tag</code> of the <code>template_object</code>.</p> <p>Before diving into a source code digging, and a no sleep night, I decided to wait a moment and ask the lifesafer community of StackOverflow for help.</p> <p>Am I missing something? I am calling <code>f.label</code> with block in the wrong way? Is some parameter missing?</p> <p>Thanks!!</p>

    1. COI had the same problem with bootstrap. I ended up just making a css rule to override bootstrap: label { display: inline-block; } maybe not the most elegant solution, but it worked.

    2. COTake a look at this question: http://stackoverflow.com/questions/2457167/nest-input-inside-f-label-rails-form-generation Maybe can be useful ;)

    3. CO@Mattyx yes thanks, I already knew that question. But it's old and says that rails form does not support blocks, which is false in Rails 3.1. Plus I hoped to be able to do it with vanilla Rails syntax

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
