LookupContext is the object responsible for holding all information required for looking up templates, i.e. view paths and details.

Prepend a path to the list of view paths for the current LookupContext.

The prefixes used in render “foo” shortcuts.

Called by render in ::AbstractController::Rendering which sets the return value as the response_body.

Pick the template digest to include in the ETag.

Sets the Cache-Control header, overwriting existing directives.

Sets an HTTP 1.1 Cache-Control header of no-cache.

Sets the etag, last_modified, or both on the response, and renders a ‘304 Not Modified` response if the request is already fresh.

Cache or yield the block.

Sets an HTTP 1.1 Cache-Control header of no-store.

Sets the etag and/or last_modified on the response and checks them against the request.

Returns a response that has no content (merely headers).

Convenience accessor.

Given a key (as described in expire_fragment), returns a key array suitable for use in reading, writing, or expiring a cached fragment.

Removes fragments from the cache.

Check if a cached fragment from the location signified by key exists (see expire_fragment for acceptable formats).

Reads a cached fragment from the location signified by key (see expire_fragment for acceptable formats).

Writes content to the location signified by key (see expire_fragment for acceptable formats).

Without web-service support, an action which collects the data for displaying a list of people might look something like this:

The cookies for the current request.

Default form builder for the controller.

The form’s authenticity parameter.

Creates the authenticity token for the current request.

GET requests are checked for cross-origin JavaScript after rendering.

Creates a masked version of the authenticity token that varies on each request.

Possible authenticity tokens sent in the request.

Checks the client’s masked token to see if it matches the session token.

The actual before_action that is used to verify the CSRF token.

If verify_authenticity_token was run (indicating that we have forgery protection enabled for this request) then also verify that we aren’t serving an unauthorized cross-origin response.

Call render_body if we are streaming instead of usual render.

Sends the given binary data to the browser.

Sends the file.

Renders a template and assigns the result to self.response_body.

Similar to #render, but only returns the rendered template as a string, instead of setting self.response_body.

Override AbstractController::Base#process_action to run the process_action callbacks around the normal behavior.

Runs the callbacks for the given event.

A hook invoked every time a before callback is halted.

Delegates to the class method, but uses the instance as the subject for rescue_from handlers (method calls, instance_exec blocks).

Internal handler lookup.

Every time after an action is processed, this method is invoked with the payload, so you can add more information.

A hook which allows you to clean up any time, wrongly taken into account in views, like database querying time.

A hook invoked every time a before callback is halted.

Allows you to measure the execution time of a block in a template and records the result to the log.

Returns the list of parameters which will be selected for wrapped.

Returns the list of enabled formats.

Returns the wrapper key which will be used to store wrapped parameters.

Performs parameters wrapping upon the request.

Delegates to the class’s .controller_name.

Delegates to the class’s .action_methods.

Returns true if a method for the action is available and can be dispatched, false otherwise.

Delegates to the class’s .controller_path.

Calls the action going through the entire Action Dispatch stack.

Takes an action name and returns the name of the method that will handle the action.

If the action name was not found, but a method called “action_missing” was found, #method_for_action will return “_handle_action_missing”.

Returns true if the name can be considered an action because it has a method defined in the controller.
