Rails＆Heroku：PG数据库无法创建数据库

Question

I have almost read every question and doc about deployment to heroku, and this is not my first time, but now in a very weird scnario when I deploy I can't create the database:

Running `rake db:create --trace` attached to terminal... up, run.8982
** Invoke db:create (first_time)
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:create
FATAL:  permission denied for database "postgres"
DETAIL:  User does not have CONNECT privilege.
/app/vendor/bundle/ruby/1.9.1/gems/activerecord-4.1.2/lib/active_record/connection_adapters/postgresql_adapter.rb:888:in `initialize'
/app/vendor/bundle/ruby/1.9.1/gems/activerecord-4.1.2/lib/active_record/connection_adapters/postgresql_adapter.rb:888:in `new'
.
.
.
.
Couldn't create database for {"adapter"=>"postgresql", "host"=>"ec2-23-23-244-144.compute-1.amazonaws.com", "encoding"=>"unicode", "database"=>"d80e387p61nnl1", "pool"=>5, "template"=>"template0", "username"=>"******", "password"=>"********", "port"=>5432}

It's not this:

FactoryGirl screws up rake db:migrate process

I took out everything related to Factory girl pretty much, everything in the spec file.

Not this either:

Rails 4.0.1 on Heroku, can't create database

any help would be veryyy very much appreciated.

Answer 1

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.rb this 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
