How to change default boolean value via submit button? - ruby-on-rails

Question

The user can choose of one of two submit buttons. If he clicks <%= f.submit :conceal %> how can the default value be made to change from false to true?
t.boolean "conceal", default: false
because right now if the user clicks the button - the default value remains false:
[1] pry(main)> Valuation.find(9)
Valuation Load (0.2ms) SELECT "valuations".* FROM "valuations" WHERE "valuations"."id" = ? LIMIT 1 [["id", 9]]
=> #<Valuation:0x007fdf26c736b8
id: 9,
conceal: false,
user_id: 1,
created_at: Thu, 23 Apr 2015 16:21:31 UTC +00:00,
updated_at: Thu, 23 Apr 2015 16:21:31 UTC +00:00,

This didn't work <%= f.submit :conceal => true %>.

Answer 1

The submit method takes an argument for what name it will show up as, but that's only useful for determining which button, if there's more than one, was used to submit the form.
What you want to do is introduce a hidden field that has the right naming convention so you can use update_attributes, or you need to test for the presence of params[:commit] which, if present, means someone pressed that button:
if (params[:commit] == 'conceal')
#valuation.conceal = true
end
