- Only validate if custom_fields are loaded, so that we don't trigger a db query
- Only validate public user fields, not all custom_fields
This commit also reverts the unrelated spec changes in ba148e08, which were required to work around these issues
Currently we don’t apply watched words to custom user fields nor user
profile fields.
This led to users being able to use blocked words in their bio, location
or some custom user fields.
This patch addresses this issue by adding some validations so it’s not
possible anymore to save the User model or the UserProfile model if they
contain blocked words.
It's very easy to forget to add `require 'rails_helper'` at the top of every core/plugin spec file, and omissions can cause some very confusing/sporadic errors.
By setting this flag in `.rspec`, we can remove the need for `require 'rails_helper'` entirely.
This change both speeds up specs (less strings to allocate) and helps catch
cases where methods in Discourse are mutating inputs.
Overall we will be migrating everything to use #frozen_string_literal: true
it will take a while, but this is the first and safest move in this direction
