Instance Public methods

_insert_callbacks(callbacks, block = nil)Link

Take callback names and an optional callback proc, normalize them, then call the block with each callback. This allows us to abstract the normalization across several methods that use it.

Parameters

• callbacks - An array of callbacks, with an optional options hash as the last parameter.
• block - A proc that should be added to the callbacks.

Block Parameters

• name - The callback to be added.
• options - A hash of options to be used when adding the callback.

def _insert_callbacks(callbacks, block = nil) options = callbacks.extract_options! callbacks.push(block) if block options[:filters] = callbacks _normalize_callback_options(options) options.delete(:filters) callbacks.each do |callback| yield callback, options end end

_normalize_callback_options(options)Link

If :only or :except are used, convert the options into the :if and :unless options of ActiveSupport::Callbacks.

The basic idea is that :only => :index gets converted to :if => proc {|c| c.action_name == "index" }.

Note that :only has priority over :if in case they are used together.

only: :index, if: -> { true } # the :if option will be ignored.

Note that :if has priority over :except in case they are used together.

except: :index, if: -> { true } # the :except option will be ignored.

Options

• only - The callback should be run only for this action.
• except - The callback should be run for all actions except this action.

after_action(names, block) Link

Append a callback after actions. See _insert_callbacks for parameter details.

append_after_action(names, block) Link

Append a callback after actions. See _insert_callbacks for parameter details.

append_around_action(names, block) Link

append_before_action(names, block) Link

Append a callback before actions. See _insert_callbacks for parameter details.

If the callback renders or redirects, the action will not run. If there are additional callbacks scheduled to run after that callback, they are also cancelled.

around_action(names, block) Link

Append a callback around actions. See _insert_callbacks for parameter details.

before_action(names, block) Link

Append a callback before actions. See _insert_callbacks for parameter details.

If the callback renders or redirects, the action will not run. If there are additional callbacks scheduled to run after that callback, they are also cancelled.

prepend_after_action(names, block) Link

Prepend a callback after actions. See _insert_callbacks for parameter details.

prepend_around_action(names, block) Link

Prepend a callback around actions. See _insert_callbacks for parameter details.

prepend_before_action(names, block) Link

Prepend a callback before actions. See _insert_callbacks for parameter details.

If the callback renders or redirects, the action will not run. If there are additional callbacks scheduled to run after that callback, they are also cancelled.

skip_after_action(names) Link

Skip a callback after actions. See _insert_callbacks for parameter details.

skip_around_action(names) Link

Skip a callback around actions. See _insert_callbacks for parameter details.

skip_before_action(names) Link

Skip a callback before actions. See _insert_callbacks for parameter details.
