It would have been handy if you&#39;d posted the HAML you&#39;re using, but this is how it&#39;s done:

    %div.some{ :style =&gt; &quot;position: absolute; left: 300px; top: 300px;&quot; }





No need to use `%div`:
   
    .some{ style: &#39;position: absolute; left: 300px; top: 300px;&#39; }

Another approach in addition to the hash one by Dan Cheail is such:

    %div.some(style=&#39;position: absolute; left: 300; top: 300;&#39;)

**If you are looking inline css for image  :**

    &lt;%= image_tag( &#39;image_name.png&#39;, style: &#39;height: 25px; width: 200px; position: absolute&#39; ) %&gt;

Requested a hash special case at: https://github.com/haml/haml/issues/787 to allow us to write:

    %div{ style: { display: &quot;none&quot;, width: &quot;50px&quot; } }

much like is possible for `class: [&quot;class1&quot;, &quot;class2&quot;]`.

Let&#39;s say I have a page with a `div`. I can easily get that div with `soup.find()`.

Now that I have the result, I&#39;d like to print the WHOLE `innerhtml` of that `div`: I mean, I&#39;d need a string with ALL the html tags and text all toegether, exactly like the string I&#39;d get in javascript with `obj.innerHTML`.  Is this possible?

I want to set the placeholder value of an input box using only CSS and no JavaScript or jQuery. 

How can I do this? 

How to set placeholder value using CSS?

Here is my code:

    &lt;div class=&#39;some&#39; style=&#39;position: absolute; left: 300; top: 300;&#39;&gt;..&lt;/div&gt;

It parses only `style=&#39;position: absolute&#39;`, and doesn&#39;t parse the other styles. How can I achieve this?

Here is my code:
<pre><code class="hljs language-css">&#x3C;div class='some' style='position: absolute; left: 300; top: 300;'>..&#x3C;/div>
</code></pre>
It parses only <code>style='position: absolute'</code>, and doesn't parse the other styles. How can I achieve this?

I have a Rails controller in which I am setting a instance variable -

    @user_name = &quot;Some Username&quot;

In my .slim template I am using coffee engine to generate javascript and want to print out the user name from client-sie javascript code -


    coffee:
      $(document).ready -&gt;
        name = &quot;#{@user_name}&quot;
        alert name


But this is the javascript that is being generated??

    $(document).ready(function() {
        var name;
        name = &quot;&quot; + this.my_name;
        alert(name);
    }

**How do I access controller instance variables in my CoffeeScript code??**

I am tagging this as haml since I am guessing haml will have the same issue when using CoffeeScript .



How to access instance variables in CoffeeScript engine inside a Slim template

I have a Rails application and I&#39;m using jQuery to query my search view in the background. There are fields `q` (search term), `start_date`, `end_date` and `internal`. The `internal` field is a checkbox and I&#39;m using the `is(:checked)` method to build the url that is queried:

    $.getScript(document.URL + &quot;?q=&quot; + $(&quot;#search_q&quot;).val() + &quot;&amp;start_date=&quot; + $(&quot;#search_start_date&quot;).val() + &quot;&amp;end_date=&quot; + $(&quot;#search_end_date&quot;).val() + &quot;&amp;internal=&quot; + $(&quot;#search_internal&quot;).is(&#39;:checked&#39;));

Now my problem is in `params[:internal]` because there is a string either containing &quot;true&quot; or &quot;false&quot; and I need to cast it to boolean. Of course I can do it like this:

    def to_boolean(str)
         return true if str==&quot;true&quot;
         return false if str==&quot;false&quot;
         return nil
    end

But I think there must be a more Ruby&#39;ish way to deal with this problem! Isn&#39;t there...?

String &quot;true&quot; and &quot;false&quot; to boolean

I&#39;m new to Capybara and testing on Rails in general, so please forgive me if this is a simple answer.

I&#39;ve got this test

    it &quot;should be able to edit an assignment&quot; do
        visit dashboard_path
        select(@project.client + &quot; - &quot; + @project.name, :from =&gt; &quot;assignment_project_id&quot;)
        select(@team_member.first_name + &quot; &quot; + @team_member.last_name, :from =&gt; &quot;assignment_person_id&quot;)
        click_button &quot;Create assignment&quot;
        page.should have_content(@team_member.first_name)
    end

it passes as is, but if I add :js =&gt; true it fails with

    cannot select option, no option with text &#39;Test client - Test project&#39; in select box &#39;assignment_project_id&#39;

I&#39;m using FactoryGirl to create the data, and as the test passes without JS, I know that part is working. 

I&#39;ve tried with the default JS driver, and with the :webkit driver (with capybara-webkit installed)

I guess I don&#39;t understand enough what turning on JS for Capybara is doing.

Why would the test fail with JS on?

Capybara with :js =&gt; true causes test to fail

While running an app how do you select a user by email address and then set the password manually within `rails console` for Devise?

Also, where would I go to review documentation to cover more details in this regard to manipulation of accounts while using Devise?

Devise password reset from Rails console

Can **Active Admin** use my current **Devise** user model? It already has a column named `admin`, and if it&#39;s `true`, I&#39;d like to bypass the Active admin login, when going to `/admin`.

Is this possible?

Current routes:


    #Active admin
    ActiveAdmin.routes(self)
      
    #Devise
    devise_for :admin_users, ActiveAdmin::Devise.config
    devise_for :users, :path =&gt; &quot;account&quot;

The rest is basically standard Devise + Active admin

Rails 3 - Can Active_admin use an existing user model?

How can I write something like this to include in a template, but in Haml?

    &lt;script&gt;
    $(document).ready( function() {
      $(&#39;body&#39;).addClass( &#39;test&#39; );
    } );
    &lt;/script&gt;


How do I include inline JavaScript in Haml?

I am learning Rails and I have seen these template engines. I have no experience with them (only erb).

But as I am a beginner, I am really confused. Which one do you suggest and why? Erb, Haml or Slim? Please tell your reason for preferring one over the others. And if you have any other recommendations, please let us know.

EDIT:
I am NOT looking for a winner here. I just want to hear your opinions about them, their syntax, speed of execution, and so on.

erb, haml or slim: which one do you suggest? And why?

I was evaluating **Slim** as a replacement for **HAML** in a personal project, and it doesn&#39;t appear to handle HTML5 data attributes as gracefully as HAML. I was hoping someone may have also run into this, or may have known about an option/syntax I haven&#39;t yet found in their docs.

HAML allows you to define [HTML 5 data attributes][1] simply by using nested hashes like so: 

`%a{data: {key1: &#39;val&#39;, key2: &#39;val&#39;}}`

resulting in

`&lt;a data-key1=&#39;val&#39; data-key2=&#39;val&#39;&gt;&lt;/a&gt;`
