Instance Method Details

#move_existing_card_into_payments_attributes(params) ⇒ Object

This method handles the awkwardness of how the html forms are currently set up for frontend.

This method expects a params hash in the format of:

{
  order: {
    existing_card: '123',
    ...other params...
  },
  cvc_confirm: '456', # optional
  ...other params...
}

And this method modifies the params into the format of:

{
  order: {
    payments_attributes: [
      {
        source_attributes: {
          existing_card_id: '123',
          verification_value: '456',
        },
      },
    ]
    ...other params...
  },
  ...other params...
}

#move_payment_source_into_payments_attributes(params) ⇒ Object

This method handles the awkwardness of how the html forms are currently set up for frontend.

This method expects a params hash in the format of:

{
  payment_source: {
    # The keys here are spree_payment_method.id's
    '1' => {...source attributes for payment method 1...},
    '2' => {...source attributes for payment method 2...},
  },
  order: {
    # Note that only a single entry is expected/handled in this array
    payments_attributes: [
      {
        payment_method_id: '1',
      },
    ],
    ...other params...
  },
  ...other params...
}

And this method modifies the params into the format of:

{
  order: {
    payments_attributes: [
      {
        payment_method_id: '1',
        source_attributes: {...source attributes for payment method 1...}
      },
    ],
    ...other params...
  },

#set_payment_parameters_amount(params, order) ⇒ Object

This is a strange thing to do since an order can have multiple payments but we always assume that it only has a single payment and that its amount should be the current order total. Also, this is pretty much overridden when the order transitions to confirm by the logic inside of Order#add_store_credit_payments. We should reconsider this method and its usage at some point.

This method expects a params hash in the format of:

{
  order: {
    # Note that only a single entry is expected/handled in this array
    payments_attributes: [
      {
        ...params...
      },
    ],
    ...other params...
  },
  ...other params...
}

And this method modifies the params into the format of:

{
  order: {
    payments_attributes: [
      {
        ...params...
        amount: <the order total>,
      },
    ],
    ...other params...
  },
  ...other params...
}
