Re: Create several models at once and validating

Rails
#1

You can call validation first, and proceed to saving
only if everything validates:

if @user.valid? && @team.valid?
@user.save(false)
@team.save(false)
end

the ‘valid?’ method does what you’d expect; the
‘false’ paramter to the save method means “don’t do
validation while saving” (since by the time you get to
the save statement, the validation has already
passed).

But if I do @user.save and then @team.save, whether
validations on team
failed,
the user is created but team doesn’t and I want non of
them to be
saved.

The only potential problem with this code is that you won’t get
any @team error messages in the view if @user fails to validate.
Instead you’d have to write:

valid_team = @team.valid?
if @user.valid? && valid_team
