This rule was added in rubocop-rails 2.33.
At first, I wasn't very fond of this rule. It made the code less
readable even if it improved performace in some cases.
Then I realized that in the `Admin::MachineLearning::SettingComponent`
we were using `find_by` when we should be using `find_by!` instead, and
we detected that thanks to this rule.
So, only for that reason, I'm adding this rule, but I'm fine if we
remove it.
We were using buttons with the "Enable" and "Disable" texts to
enable/disable settings. However, when machine learning settings were
introduced in commit 4d27bbeba, a switch control was introduced to
enable/disable them.
In order to keep the interface consistent, we're now using switch
controls in other sections where settings are enabled/disabled. We can
even use the same code in the machine learning settings as well.
We're also removing the confirmation dialog to enable/disable a setting,
since the dialog is really annoying when changing several settings and
this action can be undone immediately. The only setting which might need
a confirmation is the "Skip user verification" one; we might add it in
the future. Removing the confirmation here doesn't make things worse,
though; the "Are you sure?" confirmation dialog was also pretty useless
and users would most likely blindly accept it.
Note Capybara doesn't support finding a button by its `aria-labelledby`
atrribute. Ideally we'd write `click_button "Participatory budgeting"`
instead of `click_button "Yes"`, since from the user's point of view the
"Yes" or "No" texts aren't button labels but indicators of the status of
the setting. This makes the code a little brittle since tests would pass
even if the element referenced by `aria-labelledby` didn't exist.
