ActiveRecord AND + OR condition with multiple criteria - ruby-on-rails

Question

I'm using ActiveRecord to build a query and I got a parenthesis issue with generated SQL.
Here is a query creating my problem
joined_users = User.joins(:consumer)
users = joined_users.where(id: (1..3), name: 'foo').or(joined_users.where(consumer: {id: (1...4))
It creates the following SQL
SELECT "users".* FROM "users" INNER JOIN "consumers" "consumer" ON "consumer"."user_id" = "users"."id" WHERE ("users"."id" BETWEEN 1 AND 3 AND "users"."name" = 'foo' OR "consumer"."id" >= 1 AND "consumer"."id" < 4)
But actually, it should be
SELECT "users".* FROM "users" INNER JOIN "consumers" "consumer" ON "consumer"."user_id" = "users"."id" WHERE (("users"."id" BETWEEN 1 AND 3 AND "users"."name" = 'foo') OR ("consumer"."id" >= 1 AND "consumer"."id" < 4))
Do you get my point?
There are missing parenthesis separating the first where to the second with the or.
Bool logic is not the same at all with and without these parenthesis.
What am I missing?

Answer 1

I your particular case there should be no difference in query result, because logical AND operator has higher priority than logical OR, so:
A && B || C && D equals (A && B) || (C && D)
ActiveRecord will add parenthesis when it is needed, for example:
User.where(id: 1..3).or(User.where(id: 4...5)).where(email: 'some')
Will result in:
SELECT "users".* FROM "users" WHERE ("users"."id" BETWEEN 1 AND 3 OR "users"."id" >= 4 AND "users"."id" < 5) AND "users"."email" = 'some'
