The previous mechanism didn't seem to work and newer Rails versions have
an easier config for this now.
Also fixing all i18n errors which were now failing specs.
In this class we properly calculated the balance taking into account the
orders in cancellation state so we need to use the new implementation if
we don't want to introduce a regression by using
`#old_oustanding_balance`.
I was initially a bit dubious because this method was checking
`order.payments` as well but now I see that was redundant. Is on
`payment_total` to take into account whether or not the order is paid or
any other payment related details.
This will let us branch by abstraction. All existing calls to
`#outstanding_balance` will go through `OrderBalance` hence, will
check the feature toggle.
Note that by default, `OrderBalance` will end up calling
`#old_outstanding_balance`. As the name states, that's exactly what
`#outstanding_balance` was so far. This means no consumers will see any
change in behavior. We just added on item in the call stack (sort of).
If these are unit tests, it's much easier to find a `describe` with the
method under test and putting all the tests exercising that method
together.
It turns out that `#update_payment_state` is by far the method that we
test the most which leads me to think:
a) this class might be doing too many things.
b) other methods might not be that well covered.
It's a code smell to have a boolean control argument.
`Permissions::Order` goes too far and assumes we want to filter out
canceled orders when using report's search params and this is not the
case.
This was initially intended to cache the result of the `#map` and
`#uniq` calls but we're not confident enough and don't want to
scopecreep this. It's still worth to point out that this is what we
need, line items' `unique orders`. Hopefully, next time we find a way to
optimize it.
#update_column(s) skips callbacks (which is useful), but it doesn't change the updated_at field on the record by default (which we should be doing in these cases).
