Innate::Action

Public Class Methods

create(hash = {}) click to toggle source

Note that the default cannot be a constant as assigning the value objects to the struct would modify them and might lead to bugs due to persisting action contents.

@param [Hash, to_hash] hash used to seed new Action instance @return [Action] action with the given defaults from hash @api stable @author manveru

# File lib/innate/action.rb, line 15
def self.create(hash = {})
  default = {:options => {}, :variables => {}, :params => []}
  new(*default.merge(hash.to_hash).values_at(*ACTION_MEMBERS))
end

Public Instance Methods

binding() click to toggle source

@return [Binding] binding of the instance for this Action @see Node#binding @api stable @author manveru

# File lib/innate/action.rb, line 42
def binding
  instance.binding
end
call() click to toggle source

Call the Action instance, will insert itself temporarily into Current.actions during the render operation so even in nested calls one can still access all other Action instances. Will initialize the assigned node and call Action#render

@return [String] The rendition of all nested calls @see Action#render Node#action_found @api stable @author manveru

# File lib/innate/action.rb, line 34
def call
  Current.actions ? wrap_in_current{ render } : render
end
copy_variables(object = instance) click to toggle source

Copy Action#variables as instance variables into the given object. Defaults to copying the variables to self.

@param [Object instance_variable_set] object @return [NilClass] there is no indication of failure or success @see Action#render @author manveru

# File lib/innate/action.rb, line 73
def copy_variables(object = instance)
  self.variables.each do |iv, value|
    object.instance_variable_set("@#{iv}", value)
  end
end
full_path() click to toggle source

Path to this action, including params, with the mapping of the current controller prepended.

# File lib/innate/action.rb, line 132
def full_path
  File.join(node.mapping, path)

# File lib/innate/action.rb, line 20
def merge!(hash)

end
sync_variables(from_action) click to toggle source

Copy the instance variable names and values from given from_action#instance into the Action#variables of the action this method is called on.
