Set default stage with Capistrano 3

Capistrano v3 is somewhat of a wrapper around Rake, so you need to realize that what's really happening is that a production task is getting run first, followed by a deploy task.

If you debug it a little, you'll find that deploy.rb doesn't get loaded when you don't type in a stage. This is because the stage's task is where deploy.rb gets loaded: Looking at lib/setup.rb, a task is defined for each stage. When run, the stage's task sets :stage, loads up the capistrano defaults, and then finally loads your deploy.rb file.

So, an easy trick would be to tell Capistrano to invoke the stage task every time you run cap by adding this to the end of your Capfile (not your deploy.rb):

Rake::Task[:production].invoke

or, using the invoke method from Capistrano's DSL:

invoke :production

This may have some unintended consequences if you actually do use multiple stages, but if you only ever use the production stage, it should work fine.

Another easy solution could be a simple shell alias, such as alias cap='cap production', but it might not work great if you have multiple projects with different stage names.

After I cd into the RAILS Root directory, issuing the command:

cap development deploy

seems to work. Earlier I was in the app/models folder and issuing the command came back with this error:

Stage not set, please call something such as cap production deploy, where production is a stage you have defined.

The old solution works for me in Capistrano 3:

cap --version#=> Capistrano Version: 3.3.5 (Rake Version: 10.4.2)

At the very top of the Capfile after these lines

# Load DSL and Setup Up Stagesrequire 'capistrano/setup'

add:

set :stage, :production

and then run you task as usual without the stage specified:

cap foo:bar
