Usage

Here are the most relevant API entries from this Gem:

### From Operations module
Operations.operations_list        # All valid Operations::Operation from Rails config
Operations.from_string(name)      # Gets the Operations::Operation by string
Operations.allows?(user, name)    # Checks if the user can execute the operation string
Operations.user_roles             # All users roles defined in the Rails config

### From Operations::Operation class
operation = Operations::Operation.new do |operation|
  # Your operation name
  operation.name = 'my_operation'

  # Allows :admin, :technician, :regular and :guest.
  # These can be set in your config/application.rb with the
  # variable config.user_roles. Example:
  #
  # module MyApp
  #   class Application < Rails::Application
  #     config.user_roles += {name: 'my_other_scope'}
  #   end
  # end
  operation.scope = :admin
end

# Or
operation = Operations::Operation.new{name: :my_operation, scope: :admin}

# Instance variable
allowed_users = operation.users     # Returns a list of users based on the scope
is_valid = operation.is_valid?      # For validation purposes

### Core extensions
# Convert a string to a list of Operations::Operations
"bf9[..]a248".to_operation         # From a UUID (example truncated)
"{\"name\":\"my_operation\",\"scope\":\"admin\"}".to_operation # From a valid JSON string
