I have an hstore field in my database where I store a lot of different
fields.
I still want getters, setters and validations for my fields so I’ve
created
an array with the fields like this:
DOCUMENT_FIELDS = %w[foo bar baz]
Then I do some meta programming to create getters and setters:
DOCUMENT_FIELDS.each do |field|
define_method(field) do
# …
end
define_method("#{field}=") do |value|
# ...
end
end
Now I would like to pass all fields to strong parameters to properly
filter
it. I tried like this:
params.require(:foo).permit(Foo::DOCUMENT_FIELDS.map(&:to_sym))
But this doesn’t work. It removes all values anyway. I guess it is
because Foo::DOCUMENT_FIELDS.map(&:to_sym) creates an array that is passed to
strong parameters (and it seems to not work with arrays).

How can I get around this?
params.require(:foo).permit(*Foo::DOCUMENT_FIELDS.map(&:to_sym))
Though if I’m honest I probably would expect you to not take the long
trip with map and to_sym, might as well just leave them as string keys
because params has indifferent access with default keys being all
string keys for security.

I forgot to say what *[] does. It will expand the array into args.
