    <p>Until recently <code>db:create</code> worked just fine, but now it is failing with the stacktrace I've posted below. It's a <code>String can't be coerced into Fixnum</code> error.</p> <p>What could be the cause of this?</p> <p>My password contains letters as well as numbers, so <a href="https://stackoverflow.com/questions/3765834/cant-convert-fixnum-to-string-during-rake-dbcreate">this</a> can't be the cause.</p> <p>The trace only points to Rails code, not my own code, which makes debugging a challenge.</p> <p>I commented out the methods in my models that use the <code>+</code> operator, but that didn't solve anything.</p> <p>My <code>database.yml</code>:</p>

    1. COHave you upgraded the OS that you are running this code on ? It could be a side effect from the warning flagged about Nokogiri or potentially another gem which needs recompilation.

    2. COThanks Grant. I haven't recently upgraded the OS but I'll recompile Nokogiri etc just to be sure.

    3. COSteven - try forcing the password to be string by surrounding with "" so that the YAML parser doesn't try to coerce to a Fixnum. Just realised you had linked to this in another SO question/answer. Have you tried this anyhow ?

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).
