Hi
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?
Cheers,
Linus

Got it myself! Splat operator to the rescue :) params.require(:foo).permit(*Foo::DOCUMENT_FIELDS.map(&:to_sym)) Den fredagen den 8:e mars 2013 kl. 10:27:50 UTC+1 skrev Linus Pettersson:> > Hi > > 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.

Thank you. I thought strong params needed symbols.
