Fixes #31723

david_balance = customers(:david).balance
Customer.where(balance: [david_balance]).to_sql

# Before: WHERE `customers`.`balance` = NULL
# After : WHERE `customers`.`balance` = 50

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

This repository is being automatically checked for code quality issues using Code Climate. You can see results for this analysis in the PR status below. Newly introduced issues should be fixed before a Pull Request is considered ready to review.

Can you more exercise tests for customer.address (mapping size: 2)?
Looks like this only work in case of mapping size: 1.

Originally, if mapping size is 1, Customer.where(fullname: customer.fullname.to_s) treated as Customer.where(name: customer.fullname.to_s). If mapping size is more than 1, not allowed as invalid value.

In this PR, Customer.where(address: customer.address.country) will be treated as Customer.where(address_street: customer.address.country, address_city: customer.address.country, address_country: customer.address.country).
At least it should not be changed to fix #31723.

Follow up of #31724.

If `composed_of` objects have multiple mappings, array predicate handler
can not correctly handle the expanded condition.

We need to handle it like polymorphic association objects.
