Normalize args by converting render "foo"
to render :action => "foo"
and render "foo/bar"
to render :file => "foo/bar"

Normalize options. :api: plugin

Normalize args and options. :api: private

end
Process the rendered format. :api: private

Process extra options. :api: plugin

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

Performs the actual template rendering. :api: public

def render_to_string(*args, &block)
options = _normalize_render(*args, &block)
render_to_body(options)
end
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. :api: plugin
# File actionpack/lib/abstract_controller/rendering.rb, line 56
def rendered_format
Mime[:text]
end
Returns Content-Type of rendered content :api: public
# File actionpack/lib/abstract_controller/rendering.rb, line 67
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)
}
end
This method should return a hash with assigns. You can overwrite this configuration per controller. :api: public
