Instance Public methods
render(*args, &block)
Normalizes arguments, options and then delegates render_to_body
and sticks the result in self.response_body
.

render_to_body(options = {})
Performs the actual template rendering.

render_to_string(*args, &block)
Raw rendering of a template to a string.
It is similar to render, except that it does not set the response_body
and it should be guaranteed to always return a string.
If a component extends the semantics of response_body
(as ActionController
extends it to be anything that responds to the method each), this method needs to be overridden in order to still return a string.

view_assigns()
This method should return a hash with assigns. You can overwrite this configuration per controller.
📝 Source code
# File actionpack/lib/abstract_controller/rendering.rb, line 64
def view_assigns
protected_vars = _protected_ivars
variables = instance_variables
variables.reject! { |s| protected_vars.include? s }
variables.each_with_object({}) { |name, hash|
hash[name.slice(1, name.length)] = instance_variable_get(name)
}
