将其他字段保存到Rails子模型

Question

I have two models: Donor and Gift . I've created has_many and belongs_to associations. In my DonorsController class, I have -

def new @donor = Donor.new gift = @donor.gifts.build end

This is defined in DonorsController -

def create    
  @donor = Donor.new(donation_params)
... etc....
end

private

  def donation_params
    params.require(:donor).permit(:first_name, :last_name, :address_1, :address_2, :city, :state, :zip, :email, :phone, gifts_attributes: [:amount, :frequency])
  end

I want to save the charge.id that I get back from Stripe after processing a payment, I'm trying it with this -

@donor.gifts.stripe_charge_id = charge.id (I also tried singular gift - didn't help).

@donor.save works just fine - including the gift fields that are on the form and in the permitted list - they all get saved to the db. But the stripe_charge_id field is blank. I've confirmed there is a charge.id value.

@donor.stripe_customer_id = customer.id is working.

I added cattr_accessor :stripe_charge_id to the Gift model.

I've tried defining set/get methods, nothing is working.

Any help would be appreciated. Everything I've googled just expounds on parent & child associations, but I don't have any problems with that.

Thanks in advance.

As @fanta said, you have a has_many relation. So you cannot set the stripe_charge_id like that. And even if you did it right, rails would not save the child just because you saved the parent.

You could do this:

@donor.gifts.update_all(:stripe_charge_id => charge.id)
