Rails 2.0.2 + RJS

Elaborate on “do not work”

Do they get called and raise an error do they not get called at all? Is the page loading at all? Are you using Firefox? Do you have Firebug? What is Firebug telling you about the AJAX request? Do you like cheese on toast? What’s the square root of 24… the questions are endless.

Have you found a solution to this. I am having the same problem.

I do something like this:

            page.replace "student_#{@student.id}", :partial =>
"show", :locals => {:rendition => @rendition}
            page.visual_effect :highlight, "student_#{@student.id}",
{:endcolor => "'#EAE8D5'", :endcolor => "'#EAE8D5'"}

If I comment out the 2nd line the replace works fine. The highlight
seems to kill any kind of javascript running.

change
   create.js
to
   create.js.rjs

I just did a refresher on rjs for rails 2

I wrote up what I changes. I was using Peepcode rjs screencast

Do you have a create.rhtml file as well? If you move it to
create.html.erb, your problem will go away.

I think you should have a create.html.erb file incase the user does
not have javascript turned on.

In the controller you have the respond_to

respond_to do |format|
   format.js #create.js.rjs
   format.html #create.html.erb
end

or a more detailed version . . .

   respond_to do |format|
      if @task.save
        format.html do
          flash[:notice] = 'Task was successfully created.'
          redirect_to{ (@task)
        end
        format.js
      else
        format.html { render :action => "new" }
        format.js { render :template => "shared/error.js.rjs" }
      end
    end

For my Highlighting I am using this code

(in the js.rjs file)
page.insert_html :bottom, 'tasks', :partial => @task # adds new
task into the partial
page['task_form'].reset #
resets the form
page.visual_effect :highlight, "task_#{@task.id}", #
highlights the just added div that has the new task
                    :startcolor => '#336699'

I use a partial in my index.html.erb view.
<div id="tasks">
  <%= render :partial => @tasks %>
</div>

_task.html.erb file
<% div_for task do %>
  <%= h(task.name) %>
<% end %>

the div_for task do gives the div an id = to task_1 (or what ever the
id of the task is.)
Example:
I have one task that has an id of 1
I add a new task. It gets an id of 2

In the rjs
1) It adds a new div, with an id = task_2, into the div on the index
view that has the id of "tasks".
2) It clears the form with the reset.
3) highlight the task_2

my form view

<% remote_form_for(:task, :url => tasks_path, :html => {:id =>
"task_form"}) do |f| %>
  <p>
    <b>Name</b><br />
    <%= f.text_field :name %>
  </p>
  <p>
    <b>Value</b><br />
    <%= f.text_field :value %>
  </p>
  <p>
    <%= f.submit "Create" %>
  </p>
<% end %>

I'm having the same problems, except I can't even seem to get any of
the effects to work or calls like 'page.call :my_function'. I've got
an index.html.erb file, and an index.hs.rjs file. The js.rjs file just
has:

page.visual_effect :highlight, "my_div"

and my controller has:

respond_to do |format|
    format.js { render :template => "index.js.rjs" }
end

But whatever I do I can't seem to make this work. It always complains
with the try/catch error that has something like "alert('RJS error:\n
\n' + e.toString())". I've also tried changing the page.visual_effect
to a page.call, and I cant make this work either. Any ideas?

Why the hell did this change in rails 2.0 anyway, what was wrong with
the way it worked, where you could just do:

render :update do |page|
   page.call :alert, "Im js"
end

And not have to worry about creating a stupid js.rjs file.
