Loading a Partial via Ajax in Rails 3 -

I'm having trouble getting the page to update. I'm completely lost and do not know where from To start, type a : Remote => for my form. True Page Initial loads written in partially wrapped in a div tag, which is called a comment, I do not know whether to create a controller or file, or even how to create, partial Submit to the user when clicking on the form. Thanks for any help.

travis,

I'm not sure which action you actually are here If you are trying to demonstrate, then suppose you want to create a new resource.

Suppose that your resource has posted

if you have used the rail to generate your postcontroller You will have a method created .

This might look like this: def @ post = post.new (param [: post]) response_to do | Format | If @ post.save format.html {redirect_to (@ post,: notice = & gt; 'Post was created successfully.')} Format.xml {render: xml = & gt; @Post ,: Status = & gt; : Created: Location = & gt; @post} and format.html {renderer: action = & gt; "New"} format.xml {Render: xml = & gt; @ Post. Errors,: Status = & gt; : Unprocessable_entity} End End End

The main part is that you need format.js in the response_to block.

When you enter a : remote = & gt; True flag on your form or link, you are telling the railroad that you want to request through Ajax, resulting in the data-remote attribute in your form Or a element, and it is used to tell controversial JavaScript to use in exchange for submitting your request. Ajax

Need to ensure that your end In your controller, make sure that a format.js response format is response_to listed in the block ( html < See examples above for / code> and xml ).

Secondly, we are going to create a create.js.erb file under your app / view / post folder. By default, the train is a action.format.erb file that matches your action and format.

In the app / view / post / create.js.erb file, you can now place your feedback in JavaScript which will update your HTML accordingly. If, for example, you had a list of posts and you wanted to add a new created at the end, then you might have something like this:

App / ideas / something / Show.html ARB / /> code

  & lt; H1 & gt; Mail & lt; / H1> & Lt; Div id = "post" & gt; & Lt;% = few posts% & gt; ; & Lt; / Div & gt; & Lt ;! - Here we will join: re-mite = & gt; True choice, which will add data-remote attribute to our form - & gt; & Lt;% = post_for post.new ,: remote = & gt; To be true F | & Gt%; & Lt;% = f.text_area: Text% & gt; & Lt;% = f.submit% & gt; & Lt;% end% & gt;   
  App / View / Post / Texture JSCB   
  // Here we are taking our newly created posts and add it to the list shown on $ ('#posts'). Append ("& lt;% = escape_javascript (posted @post)%>);   
 Finally, we believe that our post is partly something like  
  app / view / post / _post.html.erb   
  & lt; P class = "post-text" & gt; & Lt;% = @ post.text% & gt; & Lt; / P & gt;   
 I'm not sure why you are using the JavaScript framework, but here I am using jQuery. I believe if you are using Rail 3.1, then the default framework used by jQuery, otherwise you have to look for it  
 Hope it helps.
