I have to develop complex web application in symfony 2 where i have 20 database entites and many to many relationships.
I am experienced programmer but i am new to this symfony and OOP.
Is there any tutorial where i i can see many entitties and repositories and thier relationship as an example to start with
thanks
I don't know of any very complex tutorials of Symfony2 yet made to the public, but here are some good ones that helped me start out when I was first learning Symfony2:
1) Symblog: http://tutorial.symblog.co.uk/
2) Jobeet: http://sftuts.com/doc/jobeet/en/starting-up-the-project
But I probably learned the most from just reading over the thorough the book/cookbook available on the symfony2 website: http://symfony.com/doc/current/book/index.html
Symfony2 is strictly object oriented, so you might want to read up on OOP as well if you're new to the concept.
KnpBundles.com is rather complex and available on github.
LilaConceptsBestPracticeBundle is another great bundle showing Symfony 2.1 best practices (covering integration with Travis CI, Code styles fixer, Composer, etc).
I highly recommend these for everybody who is looking for best-practices (like me). :)
