Hey,
I have a form on a website that I would like to be submitted remotely
- to not have to reload the whole page. Only the form should update,
so that e.g. error messages can be displayed. Makes sense
However, with the current rails.js javascript in Rails 3, the only way
to do this is using
form_for … :remote => true
and then render a RJS in the controller, which will do… what? Try to
puzzle the form values and error messages into the invalid form?
Instead, I came up with this spontaneous extension to rails.js:
http://gist.github.com/385167
With something as easy as
form_tag … :html => { ‘data-update’ =>
‘div_with_the_form_to_be_updated’ }
I can now have the controller render HTML to update the form when it
has errors, and still RJS if I would like to do some fancy stuff in
case the submission was successful.
I assume this feature should be included in rails.js. It would take
just a few lines of smart modification.
In the far future, ActionView might even be modified to implement the
good ol’
form_tag … :update => ‘div_to_be_updated’
I would love to hear your opinion about this.
All the best!
