Constants
- DEFAULT_PROTECTED_INSTANCE_VARIABLES
Public Instance Methods
Normalize args by converting render “foo” to render :action => “foo” and render “foo/bar” to render :file => “foo/bar”. :api: plugin
# File actionpack/lib/abstract_controller/rendering.rb, line 79
def _normalize_args(action=nil, options={})
if action.respond_to?(:permitted?)
if action.permitted?
action
else
raise ArgumentError, "render parameters are not permitted"
end
elsif action.is_a?(Hash)
action
else
options
end
end
Normalize options. :api: plugin
# File actionpack/lib/abstract_controller/rendering.rb, line 95
def _normalize_options(options)
options
end
Normalize args and options. :api: private
# File actionpack/lib/abstract_controller/rendering.rb, line 112
def _normalize_render(*args, &block)
options = _normalize_args(*args, &block)
#TODO: remove defined? when we restore AP <=> AV dependency
if defined?(request) && request && request.variant.present?
options[:variant] = request.variant
end
_normalize_options(options)
options
end
Process the rendered format. :api: private
# File actionpack/lib/abstract_controller/rendering.rb, line 107
def _process_format(format, options = {})
end
Process extra options. :api: plugin
# File actionpack/lib/abstract_controller/rendering.rb, line 101
def _process_options(options)
options
end
Normalize arguments, options and then delegates #render_to_body and sticks the result in self.response_body. :api: public
# File actionpack/lib/abstract_controller/rendering.rb, line 23
def render(*args, &block)
options = _normalize_render(*args, &block)
self.response_body = render_to_body(options)
_process_format(rendered_format, options) if rendered_format
self.response_body
end
Performs the actual template rendering. :api: public
# File actionpack/lib/abstract_controller/rendering.rb, line 48
def 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 Action Controller 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 41
def render_to_string(*args, &block)
options = _normalize_render(*args, &block)
render_to_body(options)
end
Returns Content-Type of rendered content :api: public
# File actionpack/lib/abstract_controller/rendering.rb, line 53
def rendered_format
Mime::TEXT
end
This method should return a hash with assigns. You can overwrite this configuration per controller. :api: public
# File actionpack/lib/abstract_controller/rendering.rb, line 66
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
