    <p>I have a nested form that does not update the database.</p> <p><strong>Models:</strong></p> <p>User:</p> <pre><code>has_many :designs, :dependent =&gt; :restrict accepts_nested_attributes_for :designs attr_accessible :designs_attributes </code></pre> <p>Design: </p> <pre><code>belongs_to :user </code></pre> <p><strong>Designs Controller:</strong></p> <pre><code>def update @design = Design.find(params[:id]) @user = User.find_by_id(@design.user_id) @points = (@user.points + 5000) if @design.update_attributes(params[:design]) flash[:success] = "Design aproved" redirect_to designindex_path else @title = @design.name + %(, created by ) + @design.user.username render 'edit' end end </code></pre> <p>And here is the form:</p> <pre><code>&lt;%= form_for @user, :html =&gt; { :multipart =&gt; true } do |f| %&gt; &lt;%= f.hidden_field(:points, {:value =&gt; @points}) %&gt; &lt;%= f.fields_for :designs, @design do |d| %&gt; &lt;div class="field"&gt; &lt;%= d.label :total_price, %(New price) %&gt;&lt;br /&gt; &lt;%= d.text_field :total_price %&gt; &lt;/div&gt; &lt;%= d.hidden_field(:aproved, {:value =&gt; 1}) %&gt; &lt;% end %&gt; &lt;div class="actions"&gt; &lt;%= f.submit "Submit" %&gt; &lt;/div&gt; &lt;% end %&gt; </code></pre> <p>Also, when I push Submit button, it redirects me to root_path.</p> <p>Looking in the console output I found this:</p> <pre><code>Started POST "/users/101" for 127.0.0.1 at 2011-09-29 15:31:16 +0200 Processing by UsersController#update as HTML Parameters: {"utf8"=&gt;"✓", "authenticity_token"=&gt;"N16nb5i/PUPftGHs3uvnnLwrp8e/PQB88w0OU6DLGko=", "user"=&gt;{"points"=&gt;"7500", "designs_attributes"=&gt;{"0"=&gt;{"total_price"=&gt;"20", "aproved"=&gt;"1", "id"=&gt;"66"}}}, "commit"=&gt;"Submit", "id"=&gt;"101"} </code></pre> <p>The problem here seems to be the following:</p> <p>An user has_many designs, but when doing the POST request the controller does not specify which one is being updated. Anyway, the users.points attribute is neither updated.</p> <p><strong>Update</strong></p> <p>Ok, I got the problem, I have this in users_controller.rb:</p> <pre><code>before_filter :authenticate, :only =&gt; [:index, :edit, :update, :destroy] before_filter :correct_user, :only =&gt; [:edit, :update] </code></pre> <p>And I'm trying to update another user's information from an admin account. Can I do this in any way?</p> <p>Here is the code for those:</p> <pre><code>def correct_user @user = User.find(params[:id]) redirect_to(root_path) unless current_user?(@user) end def current_user?(user) user == current_user end def authenticate deny_access unless signed_in? end def signed_in? !current_user.nil? end </code></pre>

    1. COYou'll need to post the contents of `correct_user`/`authenticate` to tell. but it definitely seems to be your before_filter if you're being redirected.

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).
