Common RJS

I want to have some RJS executed whenever an xhr request is made. My
initial thought was an "application.rjs" might do this, however that
does not seem to be the case.

Is there a way to set up some RJS that is executed whenever RJS is
fired? I have code that I don''t want to repeat all over the place?

Failing the above. I thought adding a helper function the application.rb
and calling that from each .rjs file. However this does not work either.
Is there a way to call a method defined in applicaiton.rb from any .rjs
file?

thanks!

Re: Common RJS

in your controller try something like this.

format.js { render :template => "shared/error.js.rjs" }

Re: Common RJS

Not sure I understand you John - can you clarify what you mean by
> in your controller try something like this.
> 
> format.js { render :template => "shared/error.js.rjs" }
Are you saying put something in my application controller (if so, 
where?) or in the controller action method that is being fired before 
the controller/action.rjs file is executed?

If it''s the latter then that would mean repearing it on every action 
that has RJS.

What I''m really looking for is if Rails has a way of invoking a common 
RJS file on every RJS action.

My reasoning for this is there are "core" tasks that I''d like
to do
using Ajax, such as showing/hiding my flash bar depending on whether 
there is a message to display.

Many thanks for your help.

put this in your application.rb (or any appropriate helper file)

def some_common_stuff
   update_page do |page|
     page.some_rjs_stuff
     ...
   end
end

Then in your rjs files you can do

page << some_common_stuff

Here is what I tried. I put this method within my application.rb :

  def rjs_update_flash
    put "rjs update flash"
    update_page do |page|
      unless flash.empty?
        if flash[:error]
          page.replace_html(''alert_panel_message'', "<p
class=''alert_error''><img
src=''/images/warning_sign.jpg''
alt=''!''>#{flash[:error]}</p>")
        elsif flash[:notice]
          page.replace_html(''alert_panel_message'', "<p
class=''alert_notice''>#{flash[:notice]}</p>")
        end
        page.show(''alert_panel'')
      else
        page.hide(''alert_panel'')
      end
    end
  end

And, in my rjs file:

page << rjs_update_flash

My log shows a 500 internal error.

I also tried putting the method in application_helper.rb but that
didn''t
work either.

Have I done something wrong?

Re: Common RJS

This was modified from peepcodes RJS screencast ( I updated it for
rails 2)
http://peepcode.com/products/rjs-templates

They use a task list for the demo.
In the tasks_controller
-------------------------------------------------------------
  # POST /tasks
  # POST /tasks.xml
  def create
    @task = Task.new(params[:task])

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

  # PUT /tasks/1
  # PUT /tasks/1.xml
  def update
    @task = Task.find(params[:id])

    respond_to do |format|
      if @task.update_attributes(params[:task])
        flash[:notice] = ''Task was successfully updated.''
        format.html { redirect_to(@task) }
        format.xml  { head :ok }
      else
        format.html { render :action => "edit" }
        format.xml  { render :xml => @task.errors, :status
=> :unprocessable_entity }
        format.js   { render :template  => "shared/error.js.rjs" }
      end
    end
  end
-------------------------------------------------------------

When ever something is not saved or updated VIA AJAX if fires the
shared/error.js.rjs file
I gues this could be DRYed up.

the shared/error.js.rjs file just has
  page.alert "An error happened!"

It definitely should be application_helper (my bad, not quite typing  
what i was thing). It would be awfully helpful to know what the error  
was (check the log files)

This does work (on Rails 2.0.2 at least):

in application_helper.rb:

module ApplicationHelper
  def display_flash(flash)
    page.replace_html(''FlashPane'', flash[:notice])
  end
end

in your "create.js.rjs" file:

page.display_flash(flash)


You need to pass the flash hash in specifically.  I am using this now,
it works really nicely - not just for flash, you can put any RJS in
there you want.
