    <p>I have an app which runs without any problems on my development machine. When I push it to Heroku, I get the following error which causes the app to crash:</p> <pre><code>ActiveRecord::AssociationTypeMismatch (Profile(#47183120) expected, got ActiveSupport::HashWithIndifferentAccess(#35109340)) </code></pre> <p>From the logs, this is:</p> <pre><code>153 &lt;13&gt;1 2012-06-04T00:07:57+00:00 app web.1 - - Started POST "/users" for 2.124.94.147/027c5e93.bb.sky.com at 2012-06-04 00:07:57 +0000 138 &lt;13&gt;1 2012-06-04T00:07:57+00:00 app web.1 - - Processing by RegistrationsController#create as HTML 517 &lt;13&gt;1 2012-06-04T00:07:57+00:00 app web.1 - - Parameters: {"utf8"=&gt;"✓", "authenticity_token"=&gt;"ztrHyRb/VzLSNRKZI1ifP6NZfdXFacDGi6edxM7RCRM=", "user"=&gt;{"email"=&gt;"user@email.com", "username"=&gt;"user", "password"=&gt;"[FILTERED]", "password_confirmation"=&gt;"[FILTERED]", "profile"=&gt;{"full_name"=&gt;"Some Name", "birth_date(3i)"=&gt;"21", "birth_date(2i)"=&gt;"10", "birth_date(1i)"=&gt;"1985", "gender"=&gt;"0", "postcode"=&gt;"XXXX XXX", "description"=&gt;"Site designer."}}, "commit"=&gt;"Sign up"} 129 &lt;13&gt;1 2012-06-04T00:07:57+00:00 app web.1 - - Completed 500 Internal Server Error in 84ms 86 &lt;13&gt;1 2012-06-04T00:07:57+00:00 app web.1 - - 211 &lt;13&gt;1 2012-06-04T00:07:57+00:00 app web.1 - - ActiveRecord::AssociationTypeMismatch (Profile(#47001900) expected, got ActiveSupport::HashWithIndifferentAccess(#29446440)): </code></pre> <p>User model (from Devise):</p> <pre><code>class User &lt; ActiveRecord::Base # Include default devise modules.

What is the problem and how do I resolve it? I'm particularly confused because this runs on my local machine but not on Heroku (I have migrated the database).</p> <p><strong>Edit:</strong></p> <p>Apologies, it doesn't work on my development machine - I added this functionality in, it didn't work, so I added the details in the console instead and forgot to revisit it.</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).
