Run Rails applications

Server

Specify a web server for running a Rails application. You might need to install a corresponding gem to the project SDK (for example,

Available servers:

• GlassFish

• Mongrel

• Webrick

• Lighttpd

• Passenger

• Puma

• Thin

• TorqueBox

• Trinidad

• Unicorn

• Zeus

Trinidad and Torquebox notes

Both Trinidad and TorqueBox servers require the following prerequisites to be met:

• Use JRuby 1.7.x as the project interpreter.

• To debug Rails applications on these servers:

  • Add the following dependencies to your Gemfile:

    gem 'ruby-debug-base', '>= 0.10.5.rc10'
    gem 'ruby-debug-ide', '>= 0.4.23.beta10'

  • Set the value of the Debug connection timeout option to 20-25 seconds (Settings/Preferences | Build, Execution, Deployment | Debugger | Ruby).

• To run Rails applications on these servers, add the following dependencies to your Gemfile:

  gem 'torquebox'
  gem 'trinidad'

Unicorn notes

Note that Unicorn kills worker processes that take too long to respond. To avoid error messages, add the following lines to the unicorn configuration file unicorn.rb:

if ENV['IDE_PROCESS_DISPATCHER']
timeout 30 * 60 * 60 * 24
end

IP Address

Specify the IP address where the Rails server will be accessible.

Port

Specify the port to run the Rails server.

Server arguments

Type optional server arguments. You can run the rails server --help command in the terminal emulator to learn more about available arguments.

Environment

Select the required Rails environment to run the server (development, production, or test).

Dummy app

This field is only enabled for the Rails mountable engine projects. Specify the absolute path to the dummy directory. This path is required to run the engine.

Environment variables

Specify the list of environment variables as the name-value pairs, separated with semi-colons. Alternatively, click to create variables and specify their values in the Environment Variables dialog.

Ruby arguments

Specify the command-line arguments to be passed to the Ruby interpreter.

When such a run/debug configuration is launched, RubyMine analyzes the running processes, and does one of the following, depending on the presence of the running Nailgun server:

• If there is no running Nailgun server, or if there is a Nailgun server on a non-default port, or with a different gemset, then RubyMine suggests to specify the desired port number.

• If a Nailgun server runs on the default port with the required gemset, RubyMine does nothing.

• If a Nailgun server runs on a different port with the required gemset, then RubyMine suggests to specify the desired port number.

• If a Nailgun server runs on the default port with a different gemset, then RubyMine deletes the --ng argument.

Classpath property is added to Nailgun settings.

Ruby SDK

Specify the desired Ruby interpreter. You can choose the project default Ruby SDK, or select a different one from the list of configured Ruby SDKs.

Run browser

Select this option to enable opening an application automatically in a default browser.

Start JavaScript debugger automatically

Enable this option to start the JavaScript debugger.

warning

Debugging of JavaScript code is only supported in Google Chrome and in other Chromium-based browsers.

Ruby arguments

Specify the command-line arguments to be passed to the Ruby interpreter.

Ruby SDK

Specify the desired Ruby interpreter. You can choose the project default Ruby SDK, or select a different one from the list of configured Ruby SDKs.
