    <p>As you already know signature of desired methods it might be better to define them instead of using <code>method_missing</code>. You can do it like that (inside you class definition):</p> <pre><code>[:bill_date, :registration_date, :some_other_date].each do |attr| define_method("#{attr}_human") do (send(attr) || Date.today).strftime('%b %d, %Y') end define_method("#{attr}_human=") do |date_string| self.send "#{attr}=", Date.strptime(date_string, '%b %d, %Y') end end </code></pre> <p>If listing all date attributes is not a problem this approach is better as you are dealing with regular methods instead of some magic inside <code>method_missing</code>. </p> <p>If you want to apply that to all attributes that have names ending with <code>_date</code> you can retrieve them like that (inside your class definition):</p> <pre><code>column_names.grep(/_date$/) </code></pre> <p>And here's <code>method_missing</code> solution (not tested, though the previous one is not tested either):</p> <pre><code>def method_missing(method_name, *args, &amp;block) # delegate to superclass if you're not handling that method_name return super unless /^(.*)_date(=?)/ =~ method_name # after match we have attribute name in $1 captured group and '' or '=' in $2 if $2.blank? (send($1) || Date.today).strftime('%b %d, %Y') else self.send "#{$1}=", Date.strptime(args[0], '%b %d, %Y') end end </code></pre> <p>In addition it's nice to override <code>respond_to?</code> method and return <code>true</code> for method names, that you handle inside <code>method_missing</code> (in 1.9 you should override <code>respond_to_missing?</code> instead).</p>

    1. COoooo nice! I hadn't come across define_method before :) I'd still like to see the method missing implementation, but +1 for a better solution

    2. COAdded `method_missing` version, but don't use it if you can define these methods.

    3. CO@KL-7 In your `method_missing` you should directly return with super when not handling the method. Right now, the attribute handling below is always executed.

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).
