Rails - Sep 2013 - CRUD model in a bootstrap modal with jquery, ajax - best practice

Hi,

i have an model, which i want to show edit and update in a dialog via ajax. 

What i do at the moment:

 

To open the Modal and render the partial, i send an ajax request to 
controller#show with ujs

 

this is the link:

<a class="person-dialog" data-remote="true"
data-type="script"
href="/en/people/32" onclick="return false">Fidel Markus
Armstrong</a>

 

this runs the script in new.js.erb which renders the show partial inside 
the dialog and opens it.

 

To get the edit form, i do the same

<a class="person-dialog" data-remote="true"
data-type="script"
href="/en/people/32/edit" onclick="return false">Fidel
Markus Armstrong</a>

this runs edit.js.erb

 

Now: To update my model, i send the form data as json to the 
controller#update

<form accept-charset="UTF-8" action="/en/people/32"
class="form-horizontal"
data-remote="true" data-type="json"
id="edit_person_32" method="post">

 

if there is an error in the form, i do render_to_string(form_partial) 
inside the controller and respond with this inside of the json response.

Now i have the partial html inside of the json object. I do this, to get 
the rails error messages and fields_with_errors.

 

Is there a better way to do it? all the mix between script and json format 
and the partial html inside the json doesn''t feel right.

 

 

This is the ajax for the form submit:

 
$(''#dialog'').on(''submit'', ->
  
$(this).find(''form'').unbind(''ajax:beforeSend'').bind(''ajax:beforeSend'',(evt,
xhr, settings)  ->
 
 
).unbind(''ajax:success'').bind(''ajax:success'',(evt,
data, status, xhr) ->
 
    #insert Data to selectbox it there comes a type attribute with the 
request
    if xhr.status == 201 # :created
      url = data.url #this is en/people/:id
 
#     Load show dialog on success - runs show.js.erb
      $.ajax({
        url: url,
        type: ''get'',
        dataType: ''script''
      })
    else
#      Render the dialog html including the error messages and fields with 
errors
      $(''#person-dialog'').html(data.error) #data.error is the
partial
      $(''.field_with_errors
input'').first().trigger(''focus'')
      $(''.modal-header'').prepend(action)
 
    false
 
 
).unbind(''ajax:complete'').bind(''ajax:complete'',(evt,
xhr, settings) ->
  ).unbind(''ajax:error'').bind(''ajax:error'',
(evt, xhr, status, error) ->
  )
)
