    <p>I've looked around and I cannot figure out why this is working. I allow users to sign up, without needing them to upload avatars at first. However, if they wish, they can upload avatars after signing up. I allow them to edit their avatar in a "profiles" controller, not in the user controller. However, the avatar won't update. I'm using devise for the users. Code below</p> <pre><code>&lt;%= form_for edit_user_path(current_user.id), :html =&gt; { :multipart =&gt; true } do |form| %&gt; &lt;%= form.file_field :avatar %&gt; &lt;%= form.submit "upload" %&gt; &lt;% end %&gt; </code></pre> <p>And in the Users controller, I have this:</p> <pre><code>def edit @user = User.find(params[:id]) @user.update_attribute(:avatar, params[:user][:avatar]) end </code></pre> <p>And in the user model, I have this</p> <pre><code>has_attached_file :avatar, :styles =&gt; { :show =&gt; "150x150#" }, :default_url =&gt; 'missing_:style.png' </code></pre> <p>The avatar does not update or save. I'm not sure why.</p> <p>Update with new form code:</p> <pre><code>&lt;%= form_for current_user, :url =&gt; {:action =&gt; 'update'}, :html =&gt; { :multipart =&gt; true } do |form| %&gt; &lt;%= form.file_field :avatar %&gt; &lt;%= form.submit "upload" %&gt; &lt;% end %&gt; </code></pre> <p>In the profiles controller, I have this: </p> <pre><code>def update @user = User.find(params[:id]) @user.update_attribute(:avatar, params[:user][:avatar]) end </code></pre> <p>I get this error: undefined method `name' for #</p> <p>Parameters being passed on the request are below</p> <pre><code>{"utf8"=&gt;"✓", "_method"=&gt;"put", "authenticity_token"=&gt;"cxANtlyj+W+ykSnivfQTfTznkpt7yXe75E8jWI1IC+o=", "user"=&gt;{"avatar"=&gt;#&lt;ActionDispatch::Http::UploadedFile:0x000001032ac7c8 @original_filename="pictester.png", @content_type="image/png", @headers="Content-Disposition: form-data; name=\"user[avatar]\"; filename=\"pictester.png\"\r\nContent-Type: image/png\r\n", @tempfile=#&lt;File:/var/folders/x9/gvnnn6s9585gkxw40c51d3540000gn/T/RackMultipart20130622- 10366-a8ome3&gt;&gt;}, "commit"=&gt;"upload", "id"=&gt;"1"} </code></pre>

    1. COHow is your avatar attribute defined in the user model? Do you have something like `has_attached_file :avatar`?

    3. COJust out of curiosity: You wrote, you have a special profiles controller where users can upload an avatar. In your post you say: "And in the Users controller, I have this:". Typo? Or is the code placed incorrectly?

Guidance
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).
