_prefix() click to toggle source

The prefix used in render “foo” shortcuts.

119:       controller_path
120:     end

render(*args, &block) click to toggle source

Normalize arguments, options and then delegates render_to_body and sticks the result in self.response_body.

    # File lib/abstract_controller/rendering.rb, line 91
91:     def render(*args, &block)
92:       self.response_body = render_to_string(*args, &block)
93:     end

render_to_body(options = {}) click to toggle source

Raw rendering of a template to a Rack-compatible body. :api: plugin

     # File lib/abstract_controller/rendering.rb, line 106
106:     def render_to_body(options = {})
107:       _process_options(options)
108:       _render_template(options)
109:     end

render_to_string(*args, &block) click to toggle source

Raw rendering of a template to a string. Just convert the results of render_to_body into a String. :api: plugin

     # File lib/abstract_controller/rendering.rb, line 98
 98:     def render_to_string(*args, &block)
 99:       options = _normalize_args(*args, &block)
100:       _normalize_options(options)
101:       render_to_body(options)
102:     end

view_context() click to toggle source

An instance of a view class. The default view class is ActionView::Base

The view class must have the following methods: View.new[lookup_context, assigns, controller]

  Create a new ActionView instance for a controller

View#render[options]

  Returns String with the rendered template

Override this method in a module to change the default behavior.

    # File lib/abstract_controller/rendering.rb, line 85
85:     def view_context
86:       view_context_class.new(lookup_context, view_assigns, self)
87:     end

_normalize_args(action=nil, options={}) click to toggle source

141:         options, action = action, nil
142:       when String, Symbol
143:         action = action.to_s
144:         key = action.include?(//) ? :file : :action
145:         options[key] = action
146:       else
147:         options.merge!(:partial => action)

This method should return a hash with assigns. You can overwrite this configuration per controller. :api: public

127:     def view_assigns
128:       hash = {}
129:       variables  = instance_variable_names
130:       variables -= protected_instance_variables if respond_to?(:protected_instance_variables)
131:       variables.each { |name| hash[name.to_s[1..1]] = instance_variable_get(name) }
