Does a request and the request created by a "link_to ''xxx'', {:action => ''xx''} :popup => true " share flash?

I have a url called A, in its resource , this exists:
  <%= link_to ''XXX'', {:action =>
''xxx''}, :popup => true %>
and I click it and create a new request with url B
Now I have two requests, or two browser pages A and B
I click a submit button in B, it dose something back and show a Tip
"Save correctly!" in top of B
and I turn to A, and REFRESH it , and I see the same tip "Save
correctly!" in top of A!
in back end, I store the tip with flash[:notice]
So it seems they share the flash, between requests !
Can anyone tells me why ?
or tell me where i can find the answer.

Re: Does a request and the request created by a "link_to ''xx

I usually use it :

class ApplicationController < ActionController::Base

  def reset_notice
    flash[:notice] = nil
  end

end

class MyRails < ApplicationController
before_filter :reset_notice

...

end


Hope it''s helpful.

This will clear the flash container every time but sometimes you don''t 
WANT this to happen. (You''re overriding the default behaviour of the 
flash mechanism this way)

If you do want a messages to last only for the life of the current 
request try this:

flash.now[:notice] = "message"

In the original post  above it would show only for the submission of B 
but the refresh of A would not show the message.

Hope this helps.

the flash is suppose to persist to the next request (but only the next  
request). If you set flash.now[:notice] = ...
Then it won''t persist to the next request.

Re: Does a request and the request created by a "link_to ''xx

Thank you~~
So an usual usage may be:
 def A
  flash[:notice] = "I came from ActionName A"
  redirect_to :action => B
 end
am I right?

Re: Does a request and the request created by a "link_to ''xx

You can not display that flash[:notice] on :action B because action B 
doesnt have params of your notice. Try this maybe help you:

  def A
   session[:notice] = "I came from ActionName A"
   redirect_to :action => B
#that notice can be displayed only if you do render :action => B
  end

  def B
   flash[:notice] = session[:notice]
  end

Re: Does a request and the request created by a "link_to ''xx

Really?  I doubt it !
render :action => B means "Use action B''s view as this
action''s view",
not means "start a new request to B"
and in this way you just change your default view, not a "next
request"
see this from http://api.rubyonrails.org/
 "
  # Renders the template for the action "goal" within the current
controller
  render :action => "goal"
 "
 "
  the flash is suppose to persist to the next request (but only the
next
  request). If you set flash.now[:notice] = ...
  Then it won''t persist to the next request.
 "
And as I said before, it''s true that the "redirect_to"
request acts as
"the next request", and do get the flash content.
For this, use below for test:
"
     def a
    flash[:a] = "I am a"
    #render :action => ''b''
    redirect_to :action => ''b''
  end

  def b
    if flash[:a].blank?
       flash[:a] = "I am b"
    end
    render :text => flash[:a]
  end
"
It seems "link_to" request ''s parent request, I mean the
request which
has a "link_to" tag, will act as "the next request"  as I
mentioned in
the first reply
Next request ?  What actually  does next request mean ?
Can anyone give a precise definition?
Can anyone give example-usage for flash ?

Re: Does a request and the request created by a "link_to ''xx

redirect_to is the same like link_to in view, if your action
''A''
redirect to another action ''B'', all params in A are unreadable
in ''B''
unless you including params behind of :action or store in in session.

render what i mean is using all logics in def B but you will use A.rhtml 
to display all logics in B & A.

Re: Does a request and the request created by a "link_to ''xx

I think you are wrong, at least in rails 2.0.2
render to B in action A means using only logics in A and B.rhtml
just this.
You can test this in rails 2.0.2
or read the api :
http://api.rubyonrails.org/classes/ActionController/Base.html#M000452
I thought the same as you when I was using rails 1.8 or before.

If you were to use render :action => B then you should use  
flash.now[:notice] = ''hello'', so that the flash does not
persist to
the request after (but in your view you still access it as  
flash[:notice]
