Symfony 2 Tuto CRUD We will developed a small application symfony 2 which adds, display, update and deleting Entity : Model(id,name,country) Car(id,name,cv,idmodel) This video show how to generate (with symfony 2 command): -Bundle

-Controller -Create Entity -Foreign key many to one

-Config and create database -Create schema database (myphpadmin) -Create Form -Create Action Add,Update,delete,show

Create bundle 

Create a Bundle to launch the following command in the console : Generate:bundle

And then specify the following settings: 

Bundle Namespace : Tuto/ParcBundle



Bundle Name : TutoParcBundle





Configuration format : yml



Create directory structure : yes



Do you confirm generation : yes



Confirm automatic update of your Kernel : yes



Confirm automatic update of the Rooting : yes



To customize the access to a particular Bundle, need to add a prefix to the Bundle inthe Global routing file :

Projet\App\config\routing.yml

Create Controller  Controller name: TutoParcBundle:Model 

Routing format (php, xml, yml, annotation) [annotation]: yml

Template format (twig, php) [twig]:twig  New action name (press to stop adding actions): AddMAction Action route [/AddM]:

Templatename (optional) [TutoParcBundle:Model:AddM.html.twig]:  New action name (press to stop adding actions): ListMAction Action route [/ListM]: Templatename (optional) [TutoParcBundle:Model:ListM.html.twig]:

Create Controller  New action name (press to stop adding actions): UpdateMAction Action route [/UpdateM]: Templatename (optional) [TutoParcBundle:Model:UpdateM.html.twig]:  New action name (press to stop adding actions): DeleteMAction Action route [/DeleteM]:  Templatename (optional) [TutoParcBundle:Model:DeleteM.html.twig]: (press to stop adding actions)

 Do you confirm generation [yes]: Yes

Create Entity  The Entity shortcut name: TutoParcBundle:Model Configuration format (yml, xml, php, or annotation) [annotation]: annotation New field name (press to stop adding fields): name  Field type [string]:  Field length [255]:  New field name (press to stop adding fields): country  Field type [string]:  Field length [255]:  New field name (press to stop adding fields):  Do you want to generate an empty repository class [no]? Yes Do you confirm generation [yes]? Yes  Done.

Foreign Key ManyToOne

Tuto\ParcBundle\Entity\Cars @ORM\ManyToOne(targetEntity="Model")

Config And Create DataBase  source file -> app -> config -> parameters.  Symfony2 -> command -> create database

create schema  Symfony2  -> command  -> create schema

Create Form

 form symfony2-> comand -> form TutoParcBundle:Cars
