CanCanCanSee

Read-only access to roles and abilities with CanCancan. Note: Since this relies on regex-magic at the moment, it requires a particular formatting that will be further articulated upon in future docs.

Add this line to your application's Gemfile:

gem 'CanCanCanSee'

And then execute:

$ bundle

Or install it yourself as:

$ gem install CanCanCanSee

Your Ability.rb file should use a case/when statement for different roles and abilities for this to work.

Create a config/initializers/cancancansee.rb file, and if you have a normal Ability.rb file include:

abilities_type = "single"

And if you have a custom multiple Ability.rb setup include:

abilities_type = "multiple"

Then, anywhere in your code or CLI, you have access to this command:

CanCanCanSee.all_abilities

#=> {"RoleOne"=>{"can"=>["manage Object"], "cannot"=>["delete Note", "edit Thing"},
#=> "RoleTwo"=>{"can"=>["edit User"], "cannot"=>["manage Telephone"]}}

#and if you only want to see abilities for a particular slug under multiple....
CanCanCanSee.all_abilities[my_slug]

#=> {"my_slug"=>{"RoleOne"=>{"can"=>["manage Object"], "cannot"=>["delete Note", "edit Thing"},
#=> "RoleTwo"=>{"can"=>["edit User"], "cannot"=>["manage Telephone"]}},
#=> "my_other_slug"=>{"RoleOne"=>{"can"=>["manage Object"], "cannot"=>["delete Note", "edit Thing"},
#=> "RoleTwo"=>{"can"=>["edit User"], "cannot"=>["manage Telephone"]}}

• Cleanup needed for single
• Pretty Print CLI or something like rake abilities for cli!
• Confirm support for single and multiple Ability.rb files
• Capture blocks passed to abilities as well and store and render them instead of just signifying 'with block'
• Create docs to show style guidelines to have gem work
• Create post to show layout for slug-based auth
• Rake support for cancancansee:abilities
