create a projecc
project name: railsPlus
Proje oluştugunda ana sayfa ekranı gelecek, burdan olusturduğumuz projeyi seçelim.
apis&auth=>ApıS=>Google+Apı=> enabled tıkla
Görünüm böyle olmalı:
apis&auth=> credentials=>add credential=>OAuth 2.0 client ID
HomePageUrl: http://localhost:3000/ =>Save
Wep Application=>configure consent screen
Gelen ekrandı ID ve Secret Keyleri oluştu. Gelelim Rails tarafına bunun için onceki yazıda bahsedilen devise modelinin oldugu program üzerinden devam edicem.
Öncelikle User modeline name ve image adlı string alanlar ekleyelim.
$ rails g migration AddNameToUser name: string
$ rails g migration AddImageToUser image: string
$ rake db:migrate
Birde Normal kayıtlı kullanıcılara resim ekleyelim bunun için carrierview gemini kullanıcaz.
Gemfile=> gem 'carrierview'
$rails generate uploader Avatar
$rails g migration AddAvatarToUser avatar: string
$rake db:migrate
User modeline: mount_uploader :avatar, AvatarUploader
app/view/devise/registration/new.html.erb dosyalarına resim ekleme satırını ekleyelim:
<div class="field">
<%= f.file_field :avatar %>
</div>
User Modelini hazırladığımıza gore Google kullanıcı girişine geçelim. gerekli gemi ekliyoruz:
*gem 'omniauth-google-oauth2'
*gem 'omniauth' , '>= 1.0.0'
$bundle
$ rails g migration AddOmniauthToUsers provider:index uid:index
$ rake db:migrate
