Rails POST Form Don't Send Full of Data to Database - ruby-on-rails

Question

I work on beginner level web application which is save off days request of users by using simple form.
Here is codes
views/days/index.html.erb
<%= form_for #daysoff, url: {action: "create"} do |f| %>
<%= f.date_field :offdate, id: 'altField' %>
<p> User holding the fort / Yerine bakicak kisi
<%= f.collection_select(:assign_id, #people, :id, :name) %> </p>
<%= f.hidden_field :user_id, value: #user.id %>
<%= f.submit "Submit" %>
<% end %>
controllers/days_controller.rb
class DaysController < ApplicationController
unloadable
def index
#people = User.all
#user = User.current
#daysoff = Daysoff.new
# params[:daysoff][:user_id] = #user.id
end
def create
off_dates = params["daysoff"]["offdate"].try(:split,',')
off_dates.each do |off_date|
#days_off = Daysoff.new
#days_off.offdate = Date.strptime(off_date.strip, "%m/%d/%Y")
#days_off.user_id = User.current
#days_off.assign_id = params["assign_id"]
#days_off.status = 0
#days_off.save!
end
redirect_to "/days_off_redmine", :flash => { :success => "Istek gonderildi." }
end
There is no any model validation.
Database migration file.
class CreateDaysoffs < ActiveRecord::Migration
def change
create_table :daysoffs do |t|
t.date :offdate
t.integer :user_id
t.integer :assign_id
t.boolean :status
end
end
end
When i try to fill and post form,
Offdates and status filling correctly but user_id and assign_id insert db as NULL.
+----+------------+---------+-----------+--------+
| id | offdate | user_id | assign_id | status |

| 12 | 2015-07-22 | NULL | NULL | 0 |
| 13 | 2015-07-29 | NULL | NULL | 0 |
| 14 | 2015-07-30 | NULL | NULL | 0 |
| 15 | 2015-07-29 | NULL | NULL | 0 |
| 16 | 2015-07-30 | NULL | NULL | 0 |
+----+------------+---------+-----------+--------+
Why this occur like that?

Answer 1

Skipping the fact that code looks really bad...
form attributes are present in params[:daysoff], you would need to get to fields by it, for example:
to get assign_id by params[:daysoff][:assign_id]
#days_off.user_id = User.current should be rather: #days_off.user_id = User.current.id
or #days_off should have in model class added
belongs_to :user and it would be working fine, unless User.current is nil
