Shopify API: Delete Discounts And Price Rules

- 1 answer

I'm using the Shopify Python library to work with my store's orders, discounts, etc. I'm writing some tests that involve creating and deleting price rules and discounts.

def test_get_discount(self):
    random_number_string = str(randint(0,10000)) 
    price_rule = shopify.PriceRule.create({
        'title': 'TEST-PRICERULE-' + random_number_string,
        'target_type': 'line_item',
        'target_selection': 'all',
        'allocation_method': 'across',
        'value_type': 'fixed_amount',
        'value': -1000,
        'once_per_customer': True,
        'customer_selection': 'all',
        'starts_at': datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")
    })
    discount = shopify.DiscountCode.create({
        'price_rule_id': price_rule.id,
        'code': 'TEST-DISCOUNT-' + random_number_string,
        'usage_count': 1,
        'value_type': 'fixed_amount',
        'value': -1000
    })
    fetched_price_rule = shopify_utils.get_discount_codes('TEST-PRICERULE-' + random_number_string)
    self.assertIsNotNone(fetched_price_rule)
    #deleted_discount = discount.destroy()
    #self.assertIsNone(deleted_discount)
    deleted_price_rule = price_rule.delete('discounts')
    self.assertIsNone(deleted_price_rule)

Everything up to deleting works properly. I'm also able to delete a discount with no problem, but when i try to delete a price rule, it errors out with the following:

deleted_price_rule = price_rule.delete()
TypeError: _instance_delete() missing 1 required positional argument: 'method_name'

I believe that it's asking me for the nested resource name, so I've tried passing things like discounts, discount_code, etc, but no luck. I see that pyactiveresouce is using that method_name to construct a url to delete the related resource, just don't know what their API looks like as it's not very well documented for cases like this.

When i do specify a (wrong) method name, I get this error:

Any ideas hugely appreciated!

As @Tim mentioned in his response, the destroy method worked for me and successfully deleted all children instances as well as parent instance.
