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

RJS Template Test

<%= 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.

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.

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.

etc.

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

Thanks.

Wade,

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

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

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.

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.

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,

The version of my Prototype js is : 1.5.0_rc0

Is this the correct version ?

Thanks

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.

Can you post the source from your browser and your controller code?

Hi,

I have finaly figured out why RJS was not working :slight_smile: 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 :slight_smile:
