I need to save 3 kinds of records in one transaction and throw an
exception if one error occurs in any one of the models : User ->>
Proposal ->> Rating
I wrote in my controller :
...
user = User.new(......)
begin
User.transaction(user) do
user.save
proposal = Proposal.new(:user_id => @user.id, ..... )
proposal.save
rating = Rating.new( :proposal => @proposal.id, .... )
rating.save
end
rescue
render :action => ''error_action''
end
redirect_to :action => ''no_error-action''
end
I have errors in user, proposal and rating but no exception is raised ..
why ?
thanks
kad

I think that you need to change user.save proposal.save rating.save to user.save! proposal.save! rating.save! user.save returns either true or false, any errors will be found in user.errors user.save! will raise an exception on failure. - matt.

Hi Kad,
This will trap most errors
begin
do something
rescue => e
puts "Oops.. #{e.message}"
end
From memory, I think the model state is rolled back as well, so you
won''t be able to interogate Model.errors to see exactly what went
wrong.
rgds,
- matt.
