    <p>I have an application on heroku. I've cleaned database (manually). There is no tables.</p> <p>And now I have problem with running rails environment. To be precisely: the problem is absence of <code>users</code> table. The environment is needed to run <code>rake db:migrate</code>. So I cant create schema in database.</p> <p>Here goes log:</p> <pre><code>/app/vendor/bundle/ruby/2.0.0/gems/activerecord-4.0.0/lib/active_record/connection_adapters/postgresql_adapter.rb:768:in

    2. COperhaps you can try to run `heroku run pg:reset` and then after that reseed the db by using `heroku run rake db:migrate` and db:seed if necessary. Keep in mind this blows the entire db though, I'm assuming there's nothing important on there

    3. CO@derekyau, to be precise: I tried `heroku pg:reset DATABASE_URL` but it brings database to the same state (empty state).

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).
