I suspect there is a standard way to handle this issue but I haven't
found it.
In my controller create action I have a Transaction. Lets say I'm
creating a user object here.
def new
User.transaction do
@user = User.new(params[:user])
#do some stuff set success if no rollback
end
if success
goto success page
else
render :action => :new
end
end
Now the problem here is when new is rendered @user has an id and it
treats it as an edit instead of a new.
I could do a the following in the fail block
@user = User.new(params[:user])
render :action => :new
but the errors are lost (and any changes or associations i created)
Or I could nil out the id
@user.id = nil
render :action => :new
It would be nice if the rollback did this for me (sort of like Object
Transactions used to but without wiping out the errors and other
information)? In my case User has many addresses and many orders so I
also need to check and nil their IDs. yuck.
What's the best practice here?
