    <p>I'm still a relative newbie to Ruby on Rails, and I'm a complete newbie with Heroku.</p> <p>I've set up my Rails app to use postgres instead of sqlite3, both in development and in production, and I've put "gem 'pg'" in my Gemfile. And locally, my app is working just fine.</p> <p>Making it work on Heroku is a different story. After I've pushed my app to Heroku, when I type in "heroku run rake db:migrate", it tells me, "rake aborted! Specified 'postgresql' for database adapter, but the gem is not loaded. Add <code>gem 'pg'</code> to your Gemfile."</p> <p>Yes, <code>gem 'pg'</code> is in my Gemfile, but I'm still getting this error.</p> <p>What gives?</p> <p>Here's what my Gemfile looks like right now:</p> <pre><code>source 'https://rubygems.org' ruby '2.0.0' gem 'rails', '4.0.1' gem 'pg' group :assets do end gem 'bcrypt-ruby', '~&gt; 3.1.2' gem 'haml' gem 'devise', '3.0.0.rc' gem 'protected_attributes' gem 'sass-rails', '4.0.1' gem 'uglifier', '2.1.1' gem 'coffee-rails', '4.0.1' gem 'jquery-rails', '3.0.4' gem 'turbolinks', '1.1.1' gem 'jbuilder', '1.0.2' gem 'knockout-rails' # To use ActiveModel has_secure_password # gem 'bcrypt-ruby', '~&gt; 3.0.0' # To use Jbuilder templates for JSON # gem 'jbuilder' # Use unicorn as the app server # gem 'unicorn' # Deploy with Capistrano # gem 'capistrano' # To use debugger # gem 'debugger' group :doc do gem 'sdoc', '0.3.20', require: false end group :production do gem 'unicorn' gem 'rails_12factor', '0.0.2' end </code></pre> <p>Here's what my database.yml is like:</p> <pre><code>development: adapter: postgresql encoding: unicode database: financemeter pool: 5 password: test: adapter: postgresql encoding: unicode database: financemeter pool: 5 timeout: 5000 production: adapter: postgresql database: dbe67fgdnnqg88 pool: 5 timeout: 5000 user: njatxlpjjrzfoe password: HULxOtPALAk4FnzZe-_737TvPc </code></pre> <p>And here are the full error logs when I try to migrate on heroku. (Again, locally I'm fine. I'm working locally on a MacBook if that matters.)</p> <pre><code>/app/vendor/bundle/ruby/2.0.0/gems/activerecord-4.0.1/lib/active_record/connection_adapters/connection_specification.rb:58:in `rescue in resolve_hash_connection' /app/vendor/bundle/ruby/2.0.0/gems/activerecord-4.0.1/lib/active_record/connection_adapters/connection_specification.rb:55:in `resolve_hash_connection' /app/vendor/bundle/ruby/2.0.0/gems/activerecord-4.0.1/lib/active_record/connection_adapters/connection_specification.rb:46:in `resolve_string_connection' /app/vendor/bundle/ruby/2.0.0/gems/activerecord-4.0.1/lib/active_record/connection_adapters/connection_specification.rb:32:in `spec' /app/vendor/bundle/ruby/2.0.0/gems/activerecord-4.0.1/lib/active_record/connection_handling.rb:39:in `establish_connection' /app/vendor/bundle/ruby/2.0.0/gems/activerecord-4.0.1/lib/active_record/railtie.rb:176:in `block (2 levels) in &lt;class:Railtie&gt;' /app/vendor/bundle/ruby/2.0.0/gems/activesupport-4.0.1/lib/active_support/lazy_load_hooks.rb:38:in `instance_eval' /app/vendor/bundle/ruby/2.0.0/gems/activesupport-4.0.1/lib/active_support/lazy_load_hooks.rb:38:in `execute_hook' /app/vendor/bundle/ruby/2.0.0/gems/activesupport-4.0.1/lib/active_support/lazy_load_hooks.rb:28:in `block in on_load' /app/vendor/bundle/ruby/2.0.0/gems/activesupport-4.0.1/lib/active_support/lazy_load_hooks.rb:27:in `each' /app/vendor/bundle/ruby/2.0.0/gems/activesupport-4.0.1/lib/active_support/lazy_load_hooks.rb:27:in `on_load' /app/vendor/bundle/ruby/2.0.0/gems/activerecord-4.0.1/lib/active_record/railtie.rb:174:in `block in &lt;class:Railtie&gt;' /app/vendor/bundle/ruby/2.0.0/gems/railties-4.0.1/lib/rails/initializable.rb:30:in `instance_exec' /app/vendor/bundle/ruby/2.0.0/gems/railties-4.0.1/lib/rails/initializable.rb:30:in `run' /app/vendor/bundle/ruby/2.0.0/gems/railties-4.0.1/lib/rails/initializable.rb:55:in `block in run_initializers' /app/vendor/bundle/ruby/2.0.0/gems/railties-4.0.1/lib/rails/initializable.rb:54:in `run_initializers' /app/vendor/bundle/ruby/2.0.0/gems/railties-4.0.1/lib/rails/application.rb:215:in `initialize!' /app/vendor/bundle/ruby/2.0.0/gems/railties-4.0.1/lib/rails/railtie/configurable.rb:30:in `method_missing' /app/config/environment.rb:5:in `&lt;top (required)&gt;' /app/vendor/bundle/ruby/2.0.0/gems/activesupport-4.0.1/lib/active_support/dependencies.rb:229:in `require' /app/vendor/bundle/ruby/2.0.0/gems/activesupport-4.0.1/lib/active_support/dependencies.rb:229:in `block in require' /app/vendor/bundle/ruby/2.0.0/gems/activesupport-4.0.1/lib/active_support/dependencies.rb:214:in `load_dependency' /app/vendor/bundle/ruby/2.0.0/gems/activesupport-4.0.1/lib/active_support/dependencies.rb:229:in `require' /app/vendor/bundle/ruby/2.0.0/gems/railties-4.0.1/lib/rails/application.rb:189:in `require_environment!' /app/vendor/bundle/ruby/2.0.0/gems/railties-4.0.1/lib/rails/application.rb:250:in `block in run_tasks_blocks' </code></pre>

    2. COI tried that - it didn't help. I do have to wonder if it's because Heroku isn't getting updated - when I do "git push heroku master," it returns back a simple "Everything up-to-date" message without telling me my changes have been pushed.

    3. COYou do realise you have the 'pg' gem twice in your gemfile? Try removing it from the `:production` group then run `bundle update`, `bundle install` and try to push that.

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).
