Constructor Details

#initialize(sym, title, options = {}, &block) ⇒ BatchAction

Create a Batch Action

Examples:

BatchAction.new :flag

> Will create an action that appears in the action list popover

BatchAction.new(:flag) { |selection| redirect_to collection_path, notice: "#{selection.length} users flagged" }

> Will create an action that uses a block to process the request (which receives one paramater of the selected objects)

BatchAction.new("Perform Long Operation on") { |selection| }

> You can create batch actions with a title instead of a Symbol

BatchAction.new(:flag, if: proc{ can? :flag, AdminUser }) { |selection| }

> You can provide an ‘:if` proc to choose when the batch action should be displayed

BatchAction.new :flag, confirm: true

> You can pass ‘true` to `:confirm` to use the default confirm message.

BatchAction.new(:flag, confirm: "Are you sure?") { |selection| }

> You can pass a custom confirmation message through ‘:confirm`

BatchAction.new(:flag, form: {foo: :text, bar: :checkbox}) { |selection, inputs| }

> You can pass a hash of options to ‘:form` that will be rendered as form input fields for the user to fill out.
