How to edit a record in the List, using Ajax?

Hi,

After generating code of Scaffold. I am able to see the code for
List/Edit/Delete/Show operations.

Now, I want to modify the code such a way that: I can edit a record,
there itself, without taking me to a new page.

  1. link_to_remote: is not useful as edit requires form submition.
  2. form_remote_tag: is feasible but, List requires a loop to run and
    text_field doesn’t work in a loop.

Also, each record has to be considered as a seperate “div” tag, but List
uses a loop, How to generate so many div’s dynamically?

Please suggest me, if there is any other alternative to do this.

Thanks and Regards,
Sandeep.

1)in the list, change the Link “edit” to a link_to_remote calling the
edit action,
2) add a div to the list.rhtml below the content loop and give it the
id=“ajaxform”
3) in the edit action, use respond_to to check if this is an ajax call:

#somewhere in the edit action the post to edit will be received …
@post = Post.find(params[:id])

respond_to do |request|
request.html
request.rjs {
render :update { |page| page.replace_html
:“ajaxform”,:partial => ‘form’ }
}
end

this code will surely not work out of the box, i think you still have
to add the submit button, using
page.insert_html :bottom, ‘ajaxform’, ‘<input type=“submit”
value=“Save”’

or something like that… play around with it.

Hi Thorsten,

Thats a good idea. It works, I guess. Thank you.

Any other ideas, from others.
