Hi,
How to use flash[:notice] in ruby to display error messages.
I have tried it into for loop as follows:-
============ for i in 0..(params[:product][:count].to_i-1)
if params[:product][''demand''+(i).to_s].to_i >
params[:product][''quantity''+(i).to_s].to_i
flash[:notice] ="#{params[:product][''demand''+(i).to_s]}
is less than
the
#{params[:product][''quantity''+(i).to_s]}"
end
end
redirect_to :action => ''index'', :id => @product
===========
Here in above code when i get redirected to index action (on
index.rhtml) page I can see only erro rmesage asociated with last flash.
That is in above code i want to store message into flash for all
products for which above ''if'' condition becomes true. So that
i can
iterate throgh flash & see the error messages related with all products
for which ''if'' condition true.
How to do this?????
Thanx in advance.
Prash
