Can't mass-assign protected attributes: even if attr_accessible already added

Question

Can't mass assign :title, :url and :about even if attr_accessible attributes already added. It's fine on rails console but not on online form.

Post Model:

class Post < ActiveRecord::Base
    attr_accessible :about, :downv, :names, :points, :title, :upv, :url, :user_id

    belongs_to :user

end

User Model:

class User < ActiveRecord::Base
    attr_accessible :email, :password_digest, :post_id, :password, :password_confirmation, :name

    has_many :posts
    has_secure_password

    validates_presence_of :password, :on => :create
end

Post Controller create:

def create
    @post = User.new(params[:post])
    @post.upv, @post.downv, @post.points = 0, 0, 0

    @post.user_id = params[:user_id]
    @post.names = ""

    if @post.save
      redirect_to root_url, notice: "Post created."
    else
      render "new"
    end
end

My form view is is just like any other form view.
