Unless they state otherwise.
The new standard also changes the default behaviour of the Shoulda
matcher in Rspec. It now defaults to asserting that an association is
required. That needed some spec updates.
In one case, Spree::Product, I also had to update the model because the
presence validation was somehow not recognised by the Shoulda matcher.
The error message may change slightly but the outcome should be the
same.
It turns out the "tax_rate" association isn't used and wasn't working.
Same for the "voucher" one, which I added to be consistent with existing
code.
Both of these weren't caught by the specs because you can't test associations
with a custome relation with 'shouda-matchers' see: https://github.com/thoughtbot/shoulda-matchers/issues/981
Add missing, "inverse_of" and "dependent" options. Use :nullify as
for "dependent" because we would want to keep the adjustments on order
even if the voucher is deleted.
This method is named "update distribution charge". What this method actually does is delete all of the fee adjustments on an order and all it's line items, then recreate them all from scratch. We call this from lots of different places all the time, and it's incredibly expensive. It even gets called from inside of transactions being run inside callbacks. Renaming it hopefully will add a bit of clarity.
This needs to be a lot more granular!
This method name (#included) is reserved and used internally by ActiveRecord. After updating Ruby, this has changed from a silent warning to a fatal error.
We can now do things like:
```
included_tax = order.adjustments.tax.included.sum(:amount)
additional_tax = order.adjustments.tax.additional.sum(:amount)
```
This method returns the same thing as the Spree::Order#line_items_adjustments scope, but in a slightly less useful format (an array instead of a relation). The method's name is also totally inaccurate, as currently the only adjustments that appear on line items are tax adjustments for inclusive tax rates, which by definition have no effect on the price whatsoever...
