Symfony 2: Many-to-Many Relationships and Form Elements

One of the things I’m developing a love for with Symfony 2 is how Doctrine, forms and Twig work together in a fairly elegant manner. With a little bit of code and annotations, you can allow Symfony 2 to perform a lot of the heavy lifting and boiler plate code that normally is a pain-in-the-rear to handle. One such aspect in development is the many-to-many relationship mapping and subsequent introduction of that code into forms. Symfony 2 will remove all the painful setup but nailing down the right technique might make you do a little research online.

Symfony 2: Installing the Doctrine Migration Bundle on Mac OS Snow Leopard

The documentation for installing it on the main web site is really an oversimplification of what you’ll have to do on a Mac OS Snow Leopard situation as I discovered. In turn, I decided to post this blog to help others that may encounter similar problems.

Symfony 2 Impressions Thus Far

Although I gave Ruby on Rails a small try a little while back, I ended up not choosing it as my framework for the moment mostly because I felt that there was a double learning curve in familiarizing myself not only with the Rails framework but Ruby as well. I still would like to give Rails a shot another day but for the moment I want to focus on getting a project completed. Of course, I would like to try something new as well which is why I decided to investigate Symfony 2.
