Module: ResourceController::Helpers::Nested

If there is a parent, returns the relevant association proxy. Otherwise returns model.

    # File ../lib/resource_controller/helpers/nested.rb, line 62
62:         def end_of_association_chain
63:           parent? ? parent_association : model
64:         end

34:           !parent_type.nil?
35:         end

parent_association()

Returns the relevant association proxy of the parent. (i.e. /posts/1/comments # => @post.comments)

    # File ../lib/resource_controller/helpers/nested.rb, line 9
 9:         def parent_association
10:           @parent_association ||= parent_object.send(model_name.to_s.pluralize.to_sym)
11:         end

parent_model()

Like the model method, but for a parent relationship.

    # File ../lib/resource_controller/helpers/nested.rb, line 50
50:         def parent_model
51:           parent_type.to_s.camelize.constantize
52:         end

parent_object()

Returns the current parent object if a parent object is present.

    # File ../lib/resource_controller/helpers/nested.rb, line 56
56:         def parent_object
57:           parent? && !parent_singleton? ? parent_model.find(parent_param) : nil
58:         end

parent_param()

Returns the current parent param, if there is a parent. (i.e. params[:post_id])

[Source]

    # File ../lib/resource_controller/helpers/nested.rb, line 44
44:         def parent_param
45:           params["#{parent_type}_id".to_sym]
46:         end

parent_singleton?()

Returns true/false based on whether or not a parent is a singleton.

    # File ../lib/resource_controller/helpers/nested.rb, line 39
39:         def parent_singleton?
40:           !parent_type_from_request.nil? && parent_type_from_params.nil?
41:         end

parent_type()

Returns the type of the current parent

[Source]

    # File ../lib/resource_controller/helpers/nested.rb, line 15
15:         def parent_type
16:           @parent_type ||= parent_type_from_params || parent_type_from_request
17:         end

parent_type_from_params()

Returns the type of the current parent extracted from params

[Source]

    # File ../lib/resource_controller/helpers/nested.rb, line 21
21:         def parent_type_from_params
22:           [*belongs_to].find { |parent| !params["#{parent}_id".to_sym].nil? }
23:         end

parent_type_from_request()

Returns the type of the current parent extracted form a request path

[Source]

    # File ../lib/resource_controller/helpers/nested.rb, line 27
27:         def parent_type_from_request
28:           [*belongs_to].find { |parent| request.path.split('/').include? parent.to_s }
29:         end
