Question

Not possible to create MySQL database from schema.rb for Rails 4 app?

  • Posted May 24, 2014

Hi,

I followed this tutorial to deploy my first Rails app on Ubuntu / Nginx / Unicorn: https://www.digitalocean.com/community/articles/how-to-launch-your-ruby-on-rails-app-with-the-digitalocean-one-click-image

However, in my Rails production log I see this:

E, [2014-05-24T11:48:34.711858 #13238] ERROR – : Mysql2::Error: Table ‘rails.users’ doesn’t exist: SELECT users.* FROM users WHERE users.remember_token IS NULL LIMIT 1 I, [2014-05-24T11:48:34.712349 #13238] INFO – : Completed 500 Internal Server Error in 48ms

When I take a closer look at my “rails” database I can see that it contains only one table (“schema_migrations”) where there should be more than a dozen.

Running commands like

RAILS_ENV=production rake db:migrate

or

RAILS_ENV=production rake db:create db:schema:load

seems to have no effect on the database. But strangely I don’t get any error messages when running those commands.

How can I create the database for my app from schema.rb?

Thanks for any help.

Have you tried running the commands separately? <br><pre>RAILS_ENV=production rake db:create <br>RAILS_ENV=production rake db:schema:load</pre>

Thanks a lot for your help. But actually that doesn’t change much. It still won’t create my database.

Let me revise that. You can do it the way you have it, but make sure you put a semicolon after the Rails environment.
<br>RAILS_ENV=production; rake db:create db:schema:load <br>They are two separate commands.

Your rake commands need to be the first on the line. The Rails environment goes at the end. The way you have done it, you have set the Rails environment variable to “production rake db:create db:schema:load”. That’s why it doesn’t complain. You can set the environment variable to anything you want, whether it makes sense or not.
