10/32

17. On next screen, please select Symfony PHP Web frameworkand give csrf-secret as I havegiven navinder123. Click on Finish button.

18. This will create a lot of directories as follows:


11/32

19. Please click on myfirstproject and press Alt+L. This will give you symfony command box.Please type configure in Filter box. Click on configure:database in Matching Tasks and

give pgsql:dbname=myfirstproject;host=localhost postgres postgres in Parameters.

In above string:

a. pgsql is driver to PostgreSQL

b. myfirstproject is database you have in your postgresql

c. host host on which you are creatingd. postgres is username

e. postgres is password

You should create your myfirstproject database by opening pgAdmin III. The screen for

configure:database will look like as following:

20. Above command will change your/myfirstproject/config/databases.yml. Look at your dsn,username and password will changed according to configure:database command.

databases.yml will look like as following:


12/32

21.Now open /myfirstproject/config/schema.yml and create schema of your project asfollowing. Please take care of indentation and dont use tab key while creating schema. First

you have to write connection name i.e. propel, then table names i.e. blog_post and

blog_comment further they hold fieldnames like blog_post has id, title, excerpt, body,

created_at.


13/32

22. Now schema is ready. Please create model from it. Press Alt+L to invoke symfony

command box and run command:

propel:build-model

23. Above command will create a foldermodel in /myfirstproject/lib folder in project directory.In model folder one each table has two classes one is object class that will hold get and setmethods and other is peer class this class includes database operations (i.e. insert, select,

delete). The files in /myfirstprojet/lib/model are blank, these files are for you, you can write

our customized code in these files. Take a look at created directories as below:


14/32

24.Now model is ready, you can create SQL from it by using propel:build-sql. Please pressAlt+L and give propel:build-sql command as following:


15/32

25. Above command will create a file lib.model.schema.sql in /myfirstproject/data/sql whichholds sql commands to create tables and set primary and foreign key given following:

26. SQL commands created in previous step will be executed by propel:insert-sql. Press Alt+Land give command. NetBeans will ask for confirmation message. Please press Y there.


16/32


17/32

27. Above command will create two tables i.e. blog_comment and blog_post in yourPostgreSQL. Please open pgAdmin III and see the tables in myfirstproject. It must be as

following:

28. Now your database and model is ready. Create forms using propel:build-forms.Please press Alt+L and give propel:build-forms as following:


18/32

29. Above command will create form folder in /myfirstproject/lib folder of project. Aswe have discussed in Model creation each table create two forms one in base folder and other

outside base folder. You can customize form outside base folder according to your

requirement. Avoid customization of Base forms inside base folder because it will got

changed every time you execute propel:build-forms

30. Until now forms are ready. Now for database operation like Create, Read, Update,Delete you have to create modules. Symfony has commands for that also, it will create your

CRUD operation automatically for you. Use following commands

propel:generate-module frontend post BlogPost

propel:generate-module frontend comment BlogComment

Please press Alt+C to clear cache.


19/32

31. Above two commands will create two modules (i.e. two directories) in/myfirstproject/apps/frontend/modules as following:


20/32

32. Each directory here contains two folders one is actions and another is templates.Actions folder contains Controller and templates contain View of the module. Two folders in

post are shown as following:

33. Now the project is ready, we have to setup our web server. Please create an alias ofmyfirstproject by editing /etc/apache2/sites-available/mysite. Open Terminal window give

following command:

$ sudo gedit /etc/apache2/sites-available/mysite

Before last line please add following, Save the file and Exit.


21/32

34. Please restart Apache using following command:$ sudo /etc/init.d/apache2 restart

35. Now web server is also ready. Open your browser and give url as:http://localhost/myfirstproject/frontend_dev.php

Output must be as following:

36. Now give this url: http://localhost/myfirstproject/frontend_dev.php/post. You will seeit is displaying contents of your blog_post table.
http://localhost/myfirstproject/frontend_dev.phphttp://localhost/myfirstproject/frontend_dev.php/posthttp://localhost/myfirstproject/frontend_dev.phphttp://localhost/myfirstproject/frontend_dev.php/post


22/32

37. If we look at url we are using frontend_dev.php in it. What is it? It is frontcontroller to the development environment of Symfony. Symfony supports different

environments for different purposes:

The development environment: This is the environment used by web developers

when they work on the application to add new features, fix bugs etc.

(frontend_dev.php)

The test environment: This environment is used to automatically test the

application.

The production environment: This is the environment end users interact with.

(index.php)

38. In step 36, you are giving http://localhost/myfirstproject/frontend_dev.php/post.By default when we give a url it is as modulename/actionnamebut in above url you are

only giving module name i.e. post. When you do this Symfony will automatically take it as

post/index that means it is invoking index action ofpost module. It will go to controller (i.e.

/myfirstproject/apps/frontend/modules/post/actions/actions.class.php) of the post module

and go for executeIndex() function.

39. As mentioned in above step in executeIndex() function, it will put the contents ofblog_post table in blog_post_list array and give the control to indexSuccess.php template to

display contents of blog_post_list. The indexSuccess.php will look like this:
http://localhost/myfirstproject/frontend_dev.php/posthttp://localhost/myfirstproject/frontend_dev.php/posthttp://localhost/myfirstproject/frontend_dev.php/post

41. After that click on Cancel to see the saved contents. The screen will look like as

following:

42. In next step. Please open second url as:http://localhost/myfirstproject/frontend_dev.php/comment

Now click on New link. You will get an error like as following:


25/32


26/32

44. Refresh the page in step 42, You will get the comment form as following:

45. Save the content and Click Cancel to see the saved contents.

46.Now its time to format the contents of the project. Please open/myfirstproject/web/css/main.css and add some css classes as following into it:


27/32

47.Now again open browser and give url as:http://localhost/myfirstproject/frontend_dev.php/comment

You can see the effect of css classes on next screen:

48. You can change the layout of the project with single file. Please open/myfirstproject/apps/frontend/templates/layout.php and change the body part of

layout.php as following:
http://localhost/myfirstproject/frontend_dev.php/commenthttp://localhost/myfirstproject/frontend_dev.php/comment


28/32

49. Open the url given in step 47 again in browser and see the effect. The screen will look like asfollowing:

50.Now its time to create a starting module. Please create a new module by pressing Alt+L andgive command:

generate:module frontend main


29/32

51. Please delete single line in executeIndex() ofactions.class.php in/myfirstproject/apps/frontend/modules/main/actions. The screen will look like as

following:

52. Please change indexSuccess.php of/myfirstproject/apps/frontend/modules/main/templates to give a welcome message as

following:


30/32

53.Now set your starting module by editing /myfirstproject/apps/frontend/config/routing.yml

Change homepage as module: main. The file will look like as following:

:

54. Please clear cache by pressing Alt+C. Your application is ready, see it with :http://localhost/myfirstproject/frontend_dev.php/main

You can navigate to List of Posts and List of Comments


31/32

55.Now project is ready. Its time to package the project for deployment. To package the projectuse following command:

project:freeze /home//public_html/symfony-1.2.10/data/binThe screen for above command is below:


32/32

56. Above command will add three folders i.e. /myfirstproject/data/symfony,/myfirstproject/lib/symfony and /myfirstproject/web/sf into project as shown below. With

freeze command you are adding symfony library files to your project. Now your project

folder is ready to deploy.

57. Thats all the application is finished. With this tutorial I want to tell you about how todevelop a basic application using symfony and NetBeans. For detailed study you have to go

through Symfony book (http://www.symfony-project.org/get/pdf/book-1.2-en.pdf), Getting

Started (http://www.symfony-project.org/get/pdf/getting-started-1.2-en.pdf), My First Project

(http://www.symfony-project.org/get/pdf/my-first-project-1.2-en.pdf) and Forms in Action

(http://www.symfony-project.org/get/pdf/forms-1.2-en.pdf) given on Symfony website.
