Run Rails applications
RubyMine allows you to run or debug Rails applications by using the configured set of startup parameters - run/debug configurations. For instance, you can specify the following parameters for the Rails run/debug configuration: a server type (such as Puma or Passenger), IP address and port, environment (development by default), and so on. Note that for Rails projects, RubyMine automatically creates the development and production run/debug configurations with the corresponding Rails environments.
In this topic we'll show you how to:
Run the Rails server for the first time without a run configuration
Run the Rails server with a run configuration
Configure additional parameters for running the Rails server
Run the Rails server without configuring
To run the Rails server for the first time without any configuring, do the following:
Press Ctrl twice.
Type the
rails servercommand in the invoked popup and press Enter.Wait until RubyMine starts the Rails server. The Run tool window shows the application's output.
After you've run the Rails server, RubyMine automatically creates a special profile - a temporary run/debug configuration. You can customize settings of this configuration, for example, a server type, IP address and port, environment, and so on. Then, you can save the customized configuration to quickly run this configuration in the future.
Run the Rails server using a run/debug configuration
You can run the Rails server with the existing run/debug configurations in one of the following ways:
Press Ctrl twice to invoke the Run Anything popup. Start typing the required configuration name, select it from the list, and press Enter.
Select the desired configuration on the toolbar and click
Shift+F10.
Select Alt+Shift+F10 from the main menu, select the desired configuration from the list and press Enter.
Configure Rails server parameters
When you run the Rails server for the first time, RubyMine automatically creates a corresponding Railstemporary configuration, which can be saved. If necessary, you can create the Rails run/debug configuration manually from the predefined template.
To customize the run/debug configuration, do the following:
Open the Run/Debug Configuration dialog in one of the following ways:
Select from the main menu.
With the Navigation bar visible (), choose from the run/debug configuration selector.
Press Alt+Shift+F10 and then press 0.
In the opened Run/Debug Configurations dialog, select the required configuration in the Rails group, and specify its settings.
