Initializing New Users in Rails

Question

I am creating a Ruby on Rails application and I am trying to create / log in / log out.

This is a diagram for Users:

  create_table "users", :force => true do |t|
    t.string   "first_name"
    t.string   "last_name"
    t.text     "reputation"
    t.integer  "questions_asked"
    t.integer  "answers_given"
    t.string   "request"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "email_hash"
    t.string   "username"
    t.string   "hashed_password"
    t.string   "salt"
  end

User personal information (username, first and last name, email address) is filled in through POST. Other applications, such as questions_asked, reputationetc., are installed by the application, so they must be initialized when creating new users. Right now, I'm just setting each of them manually in a method createfor UsersController:

  def create
    @user = User.new(params[:user])
    @user.reputation = 0
    @user.questions_asked = 0
    @user.answers_given = 0
    @user.request = nil
    ...
  end

Is there a more elegant / efficient way to do this?

Answer 1

params [: user] - ,

def create
    params[:user].merge(
        { 
            :reputation => 0,
            :questions_asked => 0,
            :answers_given => 0
            ...
        }
    )

    @user = User.new(params[:user])
end

, after_create.

, 0, , .

  create_table "users", :force => true do |t|
    t.string   "first_name"
    t.string   "last_name"
    t.text     "reputation", :default => 0
    t.integer  "questions_asked", :default => 0
    t.integer  "answers_given", :default => 0
    t.string   "request"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "email_hash"
    t.string   "username"
    t.string   "hashed_password"
    t.string   "salt"
  end

, change_column_default,

class SetDefaultsOnUsers < ActiveRecord::Migration
  def self.up
     change_column_default "users", "reputation", 0
  end

  def self.down
     change_column_default "users", "reputation", default
  end
end
