Overview

Root module, containing confguration and pure helpers. For the setters, create an initializer config/initializers/compony.rb and call them from there.

.authentication_before_action ⇒ Object

Getter for the name of the Rails before_action that enforces authentication.

# File 'lib/compony.rb', line 77

def self.authentication_before_action
  @authentication_before_action
end

.authentication_before_action=(authentication_before_action) ⇒ Object

Setter for the name of the Rails before_action that should be called to ensure that users are authenticated before accessing the component. For instance, implement a method def enforce_authentication in your ApplicationController. In the method, make sure the user has a session and redirect to the login page if they don't.
The action must be accessible by ComponyController and the easiest way to achieve this is to implement the action in your ApplicationController. If this is never called, authentication is disabled.

Parameters:

  • authentication_before_action (Symbol) —

    Name of the method you want to call for authentication

end

.button(comp_name_or_cst, model_or_family_name_or_cst, label_opts: nil, params: nil, feasibility_action: nil, feasibility_target: nil, method: nil, **override_kwargs) ⇒ Object

Given a component and a family/model, this instanciates and returns a button component.

Parameters:

  • comp_name_or_cst (String, Symbol) —

    The component that should be loaded, for instance ShowForAll, 'ShowForAll' or :show_for_all

  • model_or_family_name_or_cst (String, Symbol, ApplicationRecord) —

    Either the family that contains the requested component, or an instance implementing model_name from which the family name is auto-generated. Examples: Users, 'Users', :users, User.first

  • label_opts (Hash) (defaults to: nil) —

    Options hash that will be passed to the label method (see Compony::ComponentMixins::Default::Labelling#label)

  • params (Hash) (defaults to: nil) —

    GET parameters to be inclued into the path this button points to. Special case: e.g. format: :pdf -> some.url/foo/bar.pdf

  • feasibility_action (Symbol) (defaults to: nil) —

    Name of the feasibility action that should be checked for this button, defaults to the component name

  • feasibility_target (Symbol) (defaults to: nil) —

    Name of the feasibility target (subject) that the feasibility should be checked on, defaults to the model if given

  • override_kwargs (Hash) —

    Override button options, see options for Compony::Components::Button

Parameters:

  • comp_name_or_cst (String, Symbol) —

    The component that should be loaded, for instance ShowForAll, 'ShowForAll' or :show_for_all

  • args_for_path_helper (Array) —

    Positional arguments passed to the Rails helper

  • kwargs_for_path_helper (Hash) —

    Named arguments passed to the Rails helper. If a model is given to model_or_family_name_or_cst, the param id defaults to the passed model's ID.

Optionally can pass a name for extra standalone configs.

Parameters:

  • comp_name_or_cst (String, Symbol) —
