Make an ActiveRecord object preview-able, and display the preview using existing/custom templates
gem install preview
This will enable preview generation for the resource that is handled by the controller (eg: post for PostsController)
Will generate a preview button, on pressing which, the preview opens in a new tab.
(f is the form object for the model.)
previewable :actions => [:mycreate]
The preview functionality works for forms that submit to the
mycreate action, instead of the default (
previewable :template => "myshow"
The preview is generated using the myshow.html.erb template instead of the default (show.html.erb)
When the form is submitted through the preview button, it sends all the form values to the create/update actions on the server. This gem adds a before_filter to those actions, where it creates the resource instance variable (@post for PostsController) using the passed values, and then renders the template using the instance variable.
The resource preview object is not persisted - no data is written to the database.
