ActiveModel::ForbiddenAttributesError when creating new user
...ile_phone, :work_phone]
end
The form will pass say a radio selector as a string param. That's what happened in my case. The simple fix is to change enum to strings instead of symbols
enum preferred_phone: %w[home_phone mobile_phone work_phone]
# or more verbose
enum preferred_phone: ['home_phone'...
Why does C# forbid generic attribute types?
... like [PropertyReference(x => x.SomeProperty)]. Instead, you need magic strings and typeof(), which I think kind of sucks.

you can also pass a function name without quotes, but no variable can be passed.
your code does not wait for setTime...

What is the preferred syntax for initializing a dict: curly brace literals {} or the dict() function
...xample, say {1: 'one', 2: 'two'}. The second variant only works for (some) string keys. Using different kinds of syntax depending on the type of the keys would be an unnecessary inconsistency.
