    <p>I have problems displaying <code>error_messages.html.erb</code> partial when building custom validation.</p> <p>I have for instance, a form to make a transaction, which starts like:</p> <pre><code>&lt;%= form_for @transaction do |f| %&gt; &lt;%= render 'shared/error_messages', :object =&gt; f.object %&gt; </code></pre> <p>I have a validation which prevents a user from making a transaction with himself:</p> <pre><code>validate :self_transaction_not_possible </code></pre> <p>with</p> <pre><code> def self_transaction_not_possible bel = Belonging.find_by_id(self.belonging.id) unless bel.nil? if self.user_id == bel.user_id errors.add(:base, "You cannot perform a transaction with yourself") end end end </code></pre> <p>Then I ran such an example in the browser (initiate a transaction on a belonging I own), and I placed a debugger inside self_transaction_not_possible. I checked that the validation happens, and indeed, inside the debugger, I see that typing: self.errors.full_messages give me my error message, so validation seems to be performed...</p> <p>I would then have expected, as the object was not valid, that the error message would appear in my view, but no ... putting the debugger inside the <code>error_messages.html.erb</code> partial showed me that object.errors.any remains == {} :-/ ... </p> <p>The user is then redirected towards the page it should see when the saving process fails (validation has been performed correctly), but he never sees the error message ... </p> <p>Am I missing something obvious ? ... </p>

    1. COIt's hard to distinguish your typing errors from real bugs: `<%= form_for @transaction, do |f| %>` - what the comma is doing here? `<%= render 'shared/error_messages'; :object => f.object %>` - why did you put semicolon here? `unless bel.nil ?` - space after `nil` was intentional? And so on...

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).
