ActiveRecord still save parent object if validations on children fail

With a relationship setup like:

class Parent < ActiveRecord::Base
  has_many :children
end

class Child < ActiveRecord::Base
  belongs_to :parent
  validates_presence_of :first_name
end

p = Parent.new
p.children.build

p.save
=> false

p.errors
=> {:children => ["is invalid"]}

Is there a way to keep the validations on the child object, but not have their failed validation block the save of the parent?

It's not rails style, but it answers your question. So just manage association by yourself:

p = Parent.new
p.save
c = Children.new(:parent_id => p.id)
c.save => 'first name can't be blank"

Take a look at save(options={}) in ActiveRecord::Validations.

You can pass in :validate => false to save(), which will skip the call to valid?.

This will also skip any validations on the parent object, so you may have to do something more involved if the parent has validations as well.
