    <p>To provide some background: I've been building out a personal blog and as with any other blog it requires User authentication (or atleast one User) to be in the database. So, in development I created a user right from the rails console which worked. </p> <p>However, in production I needed an authentication system in order to create posts. So what I did was attempt to install devise to handle just that, albeit I am getting the error shown below.</p> <p>I know the issue has to do with already having a pre-existing user table in my DB, but the problem is - when trying to run rake db:migrate to drop the table I get an error, which ultimately, has me at a stand-still.</p> <p>Please advise.</p> <p>github: <a href="https://github.com/Apane/Blogit_blog" rel="nofollow">https://github.com/Apane/Blogit_blog</a> </p> <pre><code>rake db:migrate == DeviseCreateUsers: migrating ============================================== -- create_table(:users) rake aborted!

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).
