Question

I have form, and date_select there

here is my form (in edit view)

=form_for @user do |f|
  %p
    = f.date_select('user','birthday',:start_year => 1940)

here is my edit action

def edit
      @user = User.find(params[:id])
 end

in my case it writes an error

undefined method `merge’ for “birthday”:String

i have attribute birthday:date, also i tryed on string attribute but it didnt work. So how to use date select in my case?(also how to validate it? and how to set default values?)

Thanks in advance

You don’t need to add the argument for the user, it is already contained in the f variable.

=form_for @user do |f|
  %p
    = f.date_select(:birthday,:start_year => 1940)
