    <p>At end of Chapter 9 of Hartl's Rails Tutorial (2nd Edition) ran into an error when populating the db using a rake task. Ended up resolving it, but not sure what went wrong. In case anyone else hits this error, here's what I did. If anyone knows what went wrong, please comment --I'd love to know. Thanks!</p> <p>Ran these commands</p> <pre><code>$ git push heroku $ heroku run rake db:migrate $ heroku pg:reset SHARED_DATABASE --confirm &lt;name-heroku-gave-to-your-app&gt; $ heroku run rake db:populate </code></pre> <p>Then, got this error:</p> <pre><code>rake aborted! PGError: ERROR: relation "users" does not exist : SELECT a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc, a.attnotnull FROM pg_attribute a LEFT JOIN pg_attrdef d ON a.attrelid = d.adrelid AND a.attnum = d.adnum WHERE a.attrelid = '"users"'::regclass AND a.attnum &gt; 0 AND NOT a.attisdropped ORDER BY a.attnum Tasks: TOP =&gt; db:populate (See full trace by running task with --trace) </code></pre> <p>Couldn't figure out what was wrong. Then came across this post: <a href="https://stackoverflow.com/questions/5450930/heroku-postgres-error-pgerror-error-relation-organizations-does-not-exist">Heroku Postgres Error: PGError: ERROR: relation &quot;organizations&quot; does not exist (ActiveRecord::StatementInvalid)</a></p> <p>From that, I just ran these commands:</p> <pre><code>heroku run rake db:reset heroku run rake db:migrate heroku run rake db:populate </code></pre> <p>Now the app is working. Still not clear to me why I got that error when resetting SHARED_DATABASE ... If anyone knows, curious to find out.</p>

    1. COCalling `pg:reset` after calling `db:migrate` would have emptied your database and reset all migrations. The second time, when you migrated *after* resetting, the tables you were trying to populate should actually have existed :^)

    3. COah, thanks rjz. that makes sense. do you know the difference between `heroku pg:reset SHARED_DATABASE --confirm <name-heroku-gave-to-your-app>` ... and `heroku run rake db:reset` ?

Guidance
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).
