problems with multiple render and redirect

def test
	foo = redirect_to(:action => "foo").to_s and return
	render :text => foo + " bar"
end

def foo
	render :text => "foo "
end


This code prints
foo
while it should
foo bar
why? thank you

Re: problems with multiple render and redirect

No, that should display "foo " in the browser after the redirected 
request comes in to the app. The initial request hits the test action, 
which redirects to action foo *and returns* which prevents render :text 
=> foo + " bar" from ever being called. This is the correct
behavior as
well because you can only render or redirect once per action. On the 
second request (from the redirect), the browser will hit the foo action 
and display "foo ".

Re: problems with multiple render and redirect

thank you for quick response.
the reason i asked is because i need to call multiple actions from one
controller action in sequence
like
def daily
    log += render or redirect_to or render_to_string(:controller =>
''another_controller'', :action =>
''someaction'')
    log += render or redirect_to or render_to_string(:controller =>
''another_controller'', :action =>
''someaction'')
    ...
    render :text => log
end

i am not sure how to do this. i thought ''and return'' at the
and of
render call would do it, but that does not work. what is the right
way?

Calling render_xxx doesn''t actually execute the code for the specified
action. What are you actually trying to do ?

You can call other actions from the controller you''re running in  
(since actions are just public instance methods), calling the actions  
from another controllers is another subject (since you''d have to  
create the instance of that controller yourself and set it up  
appropriately).

Sounds like these actions you''re calling should actually be model  
code, at which point it becomes easy.

Re: problems with multiple render and redirect

Thank you for the answer.
Do you know how I can create instances of the other controllers? I do
need to keep them as controllers (not models) as they are controllers
and sometimes are called directly by clients. Basically I just need to
batch a bunch of calls to multiple controllers in a row, and
collecting results.

thank you.

Re: problems with multiple render and redirect

I found the answer I was looking for :) here
http://matthall.wordpress.com/2006/12/06/how-to-execute-a-rails-controller-action-via-cron/
it turn out I need to add
require ''action_controller/integration'' to environment.rb
then run a script with something like
./script/runner -e production "app
ActionController::Integration::Session.new; app.get ''account/
send_newsletters''"
