Background:
As part of our Rails 6 upgrade process, I've encountered an issue related to the format: false constraint. In Rails 6, there have been changes in the way constraints are handled, specifically involving the use of Regexp.union(re).
Issue:
The particular error we're facing is a TypeError: No implicit conversion of false into String. This is occurring due to the introduction of Regexp.union(re) in Rails 6, which expects string values and does not accept boolean values.
Proposed Solution:
To address this issue, we're proposing the removal of the format: false constraint. In our investigation, we found that the Rails 6 update now relies on Regexp.union(re), which only accepts string values in constraints.
Testing:
We have already added test cases to validate the behavior after removing the format: false constraint. These tests are aimed at ensuring the smooth functioning of our application under the Rails 6 environment.
