Usage

Formgen provides a backend to manage your forms and some helpers to integrate them into your page. The backend can be called by linking to the formgen.forms_path.

Helper: render_form

The basic call to render a form in your views. Multiple arguments are allowed to customize the behaviour of the form.

• id: The id that will be used to identify the form or
• path: The path will be used to identify the form.
• options:
  • flash [true]: Display flash notices
  • remember [false]: Remember input of the user
  • submit_text: Alternative text for the submit button

Helper: render_form_editor

Renders the complete editor for forms and questions.

• id: The id that will be used to identify the form or
• path: The path will be used to identify the form.
• options:
  • fields_only [false]

Helper: render_questions_for form_for, obj

Renders the editor for questions only. It integrates into an existing nested_form. The form_for is the object of the nested_form, obj is an instance of a class, that acts like a form. Use include Formgen::ActsAsForm for this propose.

• path: The path will be used to identify the form.
• options:

Helper: render_reply_for form_for, obj

Renders the editor for answers into another form. It integrates into an existing form. The form_for is the object of the form, obj is an instance of a class, that acts like a form. Use include Formgen::ActsAsForm for this propose.

• path: The path will be used to identify the form.
• options:
  • remember [false]

Helper: save_reply_for

Saves the reply of the render_reply_for helper in the controller.

• path: The path will be used to identify the form.

Setup

You can add the following to config/initialiyers/formgen.rb.

Formgen.setup do |config|
  # My config goes here
  ...
end

Send an email to an default receiver

config.always_mail_to = 'my-email@example.com'

Every form will now send an email to my-email@example.com, even if another address is set in the form. Then it will send it to both addresses.

Set an prefix to your emails subject

If you want to set a prefix, so that you can see, from which page the email was sent, you can add the following line.

config.subject_prefix = '[MyWebpage]'

Build your own question types

config.add_question_type 1001, 'My Type',
  question_callback: ->(question, value, classes) { ... },
  display_callback: ->(value) { "My Result" },
  validation_callback: ->(value) { return !value }

1001 is the id. It should be unique and greater than 1000. My Type is the title that will be displayed. The question_callback and the validation_callback are required. The display_callback is optional. If it isn't present, the plain value will be rendered.

Don't use devise authentication

If you don't use devise or if the backend controllers should not authenticate the user, you can skip the authentication.

config.skip_authentication = true
