Rails 4.0.1 on Heroku, Can't Create Database

Rails 4.0.1 on Heroku, can't create database

I should've read the stack trace more closely. My factories.rb was creating user objects as attributes for other factories. Wrapping them in a block fixed it:

FactoryGirl screws up rake db:migrate process

Creating postgres database on Heroku with Rails 4 error

Minutes after posting this question I figured it out, and I'm hoping this might help someone else out.

The solution was to upgrade from Rails 4.1.8 to Rails 4.2.2.

Then run

heroku run rake db:schema:load

before

heroku run rake db:migrate

For some reason that wouldn't run for my project with Rails 4.1.8. So, after upgrading to Rails 4.2.2, I ran the schema load and migrate commands with no errors.

Rails & Heroku: PG db fails to create database

There are few lessons to be learnt from this problem that I came across, but first let's answer and then explain what was going on.

Short answer:

Despite removing the tests that was considered to cause the rake to break, there were other things left out that needed to be removed and it was causing problems:

1- In the application.rbthis was happening:

 config.generators do |g|
g.test_framework :rspec,
fixtures: true,
view_specs: false,
helper_specs: false,
routing_specs: false,
controller_specs: false,
request_specs: false
g.fixture_replacement :factory_girl, dir: "spec/factories"
end

2- In seed.rb file this was happening:

# user = CreateAdminService.new.call
# puts 'CREATED ADMIN USER: ' << user.email

The lesson:

1- Don't use auto app generators. In my case I was using #RailsComposer.

2- Bower on Rails is a bad decision, it can turn a very simple app to a crazy amazin jungle

Setting up PostgresQL on Heroku Rails 4

Heroku ignores your database.yml configuration, they generate one when you deploy your application and they also take care of database creation.
All you need to do is heroku run rake db:migrate and maybe a heroku run rake db:seed in case you need to seed your database.

Impressionist gem database migration failing on Heroku

Figured it out. My impressionist migration file was somehow missing from my heroku git repository. First I had to generate the impressionist migration again to create the table.

rails g impressionist

migrate it after pushing to heroku:

heroku run rails db:migrate
