similar to: Ajax form - updating with validation errors from model

What are some good ways of doing validation with AJAX in Rails (with Prototype/Scriptaculous)? I have some Ajax.InPlaceEditors, and I would like the page with the editors on it to display errors if the data given is e.g. too short, too long, wrong format... Ideally, this should be DRY in regard to the validators. A related question: is there any way of DRY between the database table field

Hi, It seems there must be a better way to do this than what I am currently doing. I have a simple app that collects a users thoughts along with their email address and their first an last name. On a page that lists all the users thoughts they can click on a link to "add a thought" which then displays a form with ajax. My current methodology for this is not very dry. If js is

I am trying to understand why model validation error reporting in Rails is so complicated compared to non ajax model validation. In my normal form I use <%= error_messages_for ''user'' %> in my view and I get a nice error message displayed when the user inputs invalid information into the form. When I convert that form to use Ajax using form_remote_tag the

Hi all, I have a ajax form creating by "form_remote_for", whose url is to create a new model by default. The page doesn''t change after the ajax call on submit button so the form is still there after the new model is created. But if I submit the form for the second time, I want to update the formerly created model using an Ajax post. I think I could render an rjs at the end of

Hi, being relativly new to RoR, I''m having a problem which I found described in this forum and somewhere else - but with no solution. I know, that it may be bad to mix table and form tags, but the first solution of an in place editing within a table looked nice: Version using form_for: <tr> <%form_for :time_record, :url => { :action => "add_time_record" } do

Hi everyone, I''m working on an file upload page that uses an ajax progress bar (http://sean.treadway.info/demo/upload/). I''ve also got validation on the uploads (must be a certain file size/mime type etc). When uploads pass validation - all is dandy. But when they fail - I can''t work out how to redisplay the form with the flash error messages (that normally appear

Has anyone successfully gotten Ajax file uploads working using form_remote_for & attachment_fu? I have seen Sean Treadway''s responds_to_parent plugin and many other samples available, and they all seen to statically generate <form> tags. Is there a way to get a file upload to work using the Rails helpers? <% form_remote_for(:message, @message, :url =>

Hello, I''m struggling my brain with this ajax issue ... Basically I have a form for creating records, and I want to submit it using Ajax. On previous versions of RoR (2.0.2) it was working, but the same methods doesn''t work on 2.2.2, and I started to make changes and changes and read forums and the api, but no way ... <% form_remote_for (:expedient, :url => {:action

Still a semi-newbie, but so far I''ve managed to solve most things with a bit of help from the Agile book, some googling around, and a bit of trial-and-error, but I''m really stuck with this one (very much an Ajax newbie): I know how to gracefully degrade an AJAX newpost type call so it can appear inline or (for those without JS support) go to a new page (put an ":href

I have a shopping cart function, and I''d like to set it up to update the cart with AJAX. My AJAX call will return a view that displays the cart items. My question is with regards to keeping things DRY. When the user goes to "view cart", that page needs to display the cart, then the cart display needs to update with AJAX calls when items are added from that page. It would

Hi, I''m confused about how form verification with AJAX works. Let''s say I have a ''new.rhtml'' view that contains a form with two fields, and the form action is ''create''. Let''s assume that I also want to do some type of data validation on one of the two fields via AJAX before I submit the form. But since I''ve already

Hi everybody, my first Rails app is a frontend for customer data pulled from a legacy postgres database. The db is encoded in Latin1, but my pages will be UTF-8. What is the best way of character encoding conversion? I haven''t found any way to have Rails deal with this natively, so I assume I have to take care of this myself, right? Where would I place my conversion code if I want

Hey I have a page with a drop list. When the user selects an option in the drop I call an action in the controller with ajax. Now, in the controller, I gather some data from the db, but how do I present these data in a nice way? I really need to make use of the html helpers, but these clearly are not available in the controller. How do I output the array that I have gathered? My view page

Granted, I''m still very much a newbie, but after reading an article on AJAX that basically states at one point that just because you can use AJAX doesn''t always mean you should, I have to ask: Why bother contacting the server (even if it is an insignificant amount of bandwidth) to validate the sanity of form data (unless you''re actually validating against something in

hi book and page is one_to_many relationship.I want to create them in a single form.But when clicking create button,the submitted params for pages are not grouped correctly, i want "book"=>{"new_pages"=>[{"name"=>"", "color"=>""}, {"name"=>"","color"=>""}] but it is

Hi, I''m trying to post to a PHP insert script and return the confirmation text in a div with Ajax.Updater, but I''m having little luck. Does anyone have any thoughts on my implementation? The page currently refreshes completely. Thanks. < rsvp.php > <html> <head> <script src="prototype.js" type="text/javascript"></script>

I''m trying to stay DRY and use respond_to as I move to AJAX in my apps, but I''m getting some mysterious behavior. Here''s a simple form I''m testing with: <%= form_remote_tag :url => {:action => ''submit''} %> <%= submit_tag ''Go'' %> <%= end_form_tag %> When I submit the following HTTP request is sent:
