I wouldn't say it's a bug because filter_type_ids
is a fallback identifier from Sequel rather than a ROM attribute. You should use where { self[:filter_type_ids].is(...) | ... }
from rom-sql.
hello @flash-gordon ,
thanks, that explains the problem, but if I change the code to:
filter_type_id = "test"
states
.where { self[:filter_type_ids].any(filter_type_id) | self[:filter_type_ids].is(nil) }
.order(:order)
I get following error:
Failure/Error:
states
.where { self[:filter_type_ids].any(filter_type_id) | self[:filter_type_ids].is(nil) }
.order(:order).to_a
NameError:
wrong constant name []
types.const_get(type_name) if types.const_defined?(type_name)
from rom-sql.
@wuarmin sorry for the confusion, I think the truth is in the middle: there's in
, there's no any
in rom-sql API, that's why it falls back to Sequel. You should use
.where { filter_type_ids.is(nil) | filter_type_ids.in(*filter_type_id) }
There's no difference between col in (1, 2, 3)
and col = any(array[1, 2, 3])
as far as I know.
from rom-sql.
Yes, there's no difference, but I cannot write it that way:
.where { filter_type_ids.is(nil) | filter_type_ids.in(*filter_type_id) }
produces
OR ("states"."filter_type_ids" IN ARRAY['test']::text[])
which is invalid and not what I need, I need
('test' = ANY("states"."filter_type_ids"))
What about adding any to rom-sql API?
from rom-sql.

I'm just saying it should have no difference at the database level. You can use inline SQL with backticks:
where { `filter_type_ids is null or filter_type_ids = any(array([#{filter_type_id.map { "'#{_1}'" }.join(',') }]))` }
A PR with adding ANY
is welcome.
