  • Symfony 2: Why You Should Move Your Logic into a Service

    In typical MVC applications, people end up storing business logic into either the controller or the model layer. The problem in this approach is that in either case, you introduce code bloat and dependencies that should not really exist. Controllers, which are essentially the observer pattern, act as a traffic light, taking requests and directing…

  • Symfony 2: Annoying Issue with Data Transformers, DateTime, Timezones and PHP.ini

    I spent almost the entire day going through the low level code of Symfony 2 trying to determine a really obscure error with my code. The issue started from dealing with using a Time type for one of my columns and having the form validate it appropriately. Unfortunately, the error message that bubbled up did…

  • 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…

  • Symfony 2: Working with the Security Layer and Database Backends

    The examples over on the Symfony 2 site regarding building a security system, while decent, are somewhat incomplete and a little confusing, especially in putting all the details together for a database backed login system. While most of the code present on the two articles work for the most part, I wanted to add a…

  • Symfony 2: Form Data Submit and Models with Validation Unit Testing Issue

    While creating a phpunit test against a form for Symfony 2, I encountered an interesting problem that made little sense to me at first (for reference, I was following an example for unit testing form types from the Symfony 2 website). The problem was that the data being submitted appeared to not be mapped correctly,…

  • Symfony 2: Unit Testing Many-to-One Validations on Entities

    From what I can tell, the Symfony 2 cookbook does not have a decent example for handling entity validations and unit testing. I looked around a bit for a good sample and found a decent answer over on Stackoverflow. But outside of setting up a base class for handling future validation test classes, the sample…

  • Symfony 2: Adding A Selection List of Entities

    The examples from the documentation on the Symfony 2 site did not explain how one could render a list of entities in the form of say a select html drop down for an object that has a one-to-many type of relationship (the sample showed a product to category relationship). Instead, what was shown was embedding…

  • Symfony 2: Day 3 Test Drive

    I created a new bundle for my application and am attempting to move towards a more serious mode of programming. Rather than working with your typical “Hello Worlds”, I decided to focus on a more complex test case that’ll help motivate me in getting a better feel for more advanced features.

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

    I learned that the DoctrineMigrationBundle does not come as part of the default Symfony 2 install and that you must manually install it. 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,…

  • 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…
