[Rails] RJS

I am trying to use RJS as shown in this tutorial :

http://www.codyfauser.com/articles/2005/11/20/rails-rjs-templates

However it does not seem to work.  I am not getting any excpetions in 
the logs. Here is what the logs say :

Parameters: {"action"=>"add",
"controller"=>"homepage"}
Rendering homepage/add

The homepage/add is named add.rjs

I know that this file is being accessed, if I put some incorrect code 
there it complains in the logs.

I am not sure that "rake rails:update" (in the application folder)
works
correctly for me.  This is because I have updated to the latest version 
of rails and then I copied conf/boot.rb to /tmp folder and did this 
command

rake rails:update:configs

According to this post

http://weblog.rubyonrails.org/articles/2006/04/09/rails-1-1-2-tiny-fix-for-gems-dependenciesI

It should update your boot.rb.  But I did a diff and the files are the 
same. This could mean that I have not got the correct js files to allow 
RJS to work?  Is there a way of checking if I have the correect JS files 
that support RJS ?

Here is ths code :

homepage/add.rjs :

page.replace_html ''header'',''RJS Template Test
Complete!''

in homepage/list
<h1 id=''header''>RJS Template Test</h1>
    <%= link_to_remote("Change Title", :url =>{ :action =>
''add'' }) %>

in the homepage controller

def add
end

By the way I am importing the javascripts like this :

<%= javascript_include_tag :defaults %>


I would appreciate any help, as I have been struggling all morning.

Thanks in advance.

Hamza

[Rails] RJS

try adding a :complete=>''alert(response.responseText)'' to
your function call.

This should pop up the RJS output and give you more information about  
why the call failed.

[Rails] Re: RJS

Keven,

Thanks fo the reply.  I have added an alert to the link.  This is what 
it is now:

<%= link_to_remote("Change Title", :url =>{:action => :add },
:complete
=> "alert(request.responseText)") %>

I do get an alert.  This is what it says :

Element.update("header","RJS Template Test Complete!"); Load
Suite
dispatch etc.

It still does not update the title (with a id of ''header'').
But it does
seem to be actioning the correct code.  Does anyone have any suggestions 
?

I even tried to put a doctype for the page.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"
lang="en"> etc.

I have also tried ''page.remove'' and
''page.insert_html''  But nothing
seems to work.

Thanks.

Hamza

I had a similar problem when I was setting the Content-Type header to be 
"text/html" for all actions.  RJS needs to be rendered with a
different
Content-Type (application/javascript or something, can''t remember right
now).  Check to see if you''re doing something like that, maybe using a 
:before_filter or similar thing to set it - when I did it, it was giving 
the exact same symptoms you''re describing.

[Rails] Re: Re: RJS

Wade,

I am not seting the content type to HTML by default.  However I did have 
the following in the file :

<meta http-equiv="Content-Type" content="text/html;
charset=utf-8"/>

I took this out but it had no effect.  I have also added this to the add 
method :

def add
  @headers["Content-Type"] = "text/javascript"
end

But all this has no effect.  However what I am doing is, I am using UTF 
characaters.  I am not sure this would effect anything ?

I will try and create an empty rails app to see if I am getting the same 
error.   Other then that I am still stuck.

By the way, Is that add method correct ?  Can i change the header like 
that when making a RJS request ?

Thanks

Hamza

Hamza,

What version is your Prototype library?  Take a look inside
public/javascripts/prototype.js to find out.

Yeah, that is correct.  Try making your rjs template only this:
page.alert(''test'') and see if you get a popup.

[Rails] Re: Re: RJS

Needless to say but a precaution; when you make rjs template for an action,
be sure you don''t have any other template view (rhtml or rxml) for the
same
action.

Cody,

Even that does not display an alert box.  I have tried multiple things 
in the add.rjs file

Rizwan,

I do not have any other view named add.

Hi,

I have finaly figured out why RJS was not working :)  My rails setup was 
going through Apache2 using fastcgi.  I went through this tutorial :

http://fo64.com/articles/2005/10/20/rails-on-breezy

However, when I turned off Apache and went through WEBrick AJAX started 
to worked :). This obvsioully meant that Apache was not sending the AJAX 
requsts to Rails.

Thank you to everyone who helped. I just need to figure out how to get 
Apache working now :)
