    <p>I have a problem that seems very simple to me, but I can't figure out the solution. So if you can be of any help, I would appreciate that very much :-)</p> <p>First of all, I used the Devise gem to create my Users.</p> <p>Here is <strong>app/models/user.rb</strong> :</p> <pre class="lang-rb prettyprint-override"><code>class User &lt; ActiveRecord::Base before_save :default_values # Include default devise modules. Others available are: # :token_authenticatable, :confirmable, # :lockable, :timeoutable and :omniauthable devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable # Setup accessible (or protected) attributes for your model attr_accessible :name, :email, :password, :password_confirmation, :remember_me, :avatar, :address, :longitude, :latitude has_many :products, dependent: :destroy has_attached_file :avatar, styles: { medium: "300x300&gt;", thumb: "50x50&gt;" }, url: "users/:id/:style/:basename.:extension", path: ":rails_root/public/assets/users/:id/:style/:basename.:extension", default_url: "users/missing/:style/missing.png" #Geokit geocoded_by :address after_validation :geocode, if: :address_changed? def default_values self.address ||= "Paris" self.geocode end end </code></pre> <p>I created a Home controller for my static pages, and my root_path is <strong>app/views/home/index.html.erb</strong> in which we can find :</p> <pre class="lang-rb prettyprint-override"><code>&lt;%= render 'new_name' %&gt; </code></pre> <p>Let's take a look at this <strong>app/views/home/_new_name.html.erb</strong> :</p> <pre class="lang-rb prettyprint-override"><code>&lt;!-- Button to trigger modal --&gt; &lt;a href="#yourName" role="button" class="btn" data-toggle="modal"&gt;OK&lt;/a&gt; &lt;!-- Modal --&gt; &lt;div id="yourName" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"&gt; &lt;div class="modal-header"&gt; &lt;button type="button" class="close" data-dismiss="modal" aria-hidden="true"&gt;×&lt;/button&gt; &lt;h3 id="myModalLabel"&gt;&lt;%= t('home.your_name') %&gt;&lt;/h3&gt; &lt;/div&gt; &lt;div class="modal-body"&gt; &lt;%= form_for(@current_user) do |f| %&gt; &lt;p&gt; &lt;%= f.label :name, t('name'), placeholder: t('home.your_name') %&gt; &lt;%= f.text_field :name %&gt; &lt;/p&gt; &lt;p&gt; &lt;%= f.submit t('update'), class: "btn"%&gt; &lt;/p&gt; &lt;% end %&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>And yes, I definitely used the bootsrap's magic ;-)</p> <p>For the record, my <strong>config/routes.rb</strong></p> <pre class="lang-rb prettyprint-override"><code>Dindon::Application.routes.draw do root to: "home#index" resources :products devise_for :users match 'users/:id' =&gt; 'users#show', :as =&gt; :user match 'users' =&gt; 'users#index' end </code></pre> <p>So, the last thing to do is configure my HomeController to give to my instance variable @current_user his new name. Here is my <strong>app/controllers/home_controller.rb</strong> :</p> <pre class="lang-rb prettyprint-override"><code>class HomeController &lt; ApplicationController def index @current_user = User.find_by_id(current_user.id) end def update @current_user.update_attributes(params[:user]) end end </code></pre> <p>But it doesn't work at all. When I click on the OK button, I have the window, I fill in the field, I click on the submit button, and it send me to the User show view, but without taking the change of name in account.</p> <p>Do you have any idea of what I did wrong ?</p>

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).
