ruby - Rails database date issues -

my web app has 2 date_select parameters in. these should passed db searching later on. cannot function. see can see inspection parameters being passed date(3i) (2i) (1i). when create migrate file tables in fails if try add (3i) etc.. i've read in rails need manipulate in controller. i'm trying failing miserably. have thought basic attribute of db table. dates etc..

any pointers? code need see.

here parameters i'm passing...

 "date(3i)"=>"19",  "date(2i)"=>"4",  "date(1i)"=>"2014",  "date_of_change(3i)"=>"19",  "date_of_change(2i)"=>"4",  "date_of_change(1i)"=>"2014",    class createposts < activerecord::migration  def change create_table :posts |t|   t.text :title   t.text :requester   t.text :requester_email   t.text :customer   t.text :contact   t.text :customer_email   t.text :customer_phone   t.string :type_of_change     t.timestamps 

ok seem getting further here.... on rails console can see following date has been passed date_of_change still nil.

  => #<post id: 7, title: "", requester: "", requester_email: "", customer: "", contact:       customer_email: "", customer_phone: "", type_of_change: "service change", created_at:    "2014-04-19 21:32:53", updated_at: "2014-04-19 21:32:53", implementer: "", ticket: "",    date: "2014-04-19", date_of_change: nil>  

ok. have typo on permitted values. let me change that.

say model concert, migration file should this. it?

class createconcerts < activerecord::migration   def change     create_table :concerts |t|       t.string :artist       t.string :venue       t.date :date       #correct format date       t.date :date_of_change        t.timestamps     end   end end 

so in case believe should

 class createposts < activerecord::migration  def change     create_table :posts |t|        t.text :title        t.text :requester        t.text :requester_email        t.text :customer        t.text :contact        t.text :customer_email        t.text :customer_phone        t.string :type_of_change        t.date :date        t.date :date_of_change         t.timestamps        end     end   end 

then run rake db:migrate

in post controller @ bottom should

def post_params       params.require(:post).permit(:title, :requester, :requester_email, :customer, :contact, :customer_email, :customer_phone, :type_of_change, :date, :date_of_change) end
