Using email instead of login name in django
Hi all, Firstly, this is not the question how to authenticate on email/password pair, but rather how to produce logical, and if you like, beautiful data structure. I want to use emails as user names in a given django project. However, I am unable to re-use fields provided by auth.User model for at least two reasons: auth.User.usernam...

MVC: Is it considered bad form to give a DTO a reference to the data access layer?
Is it considered bad form to give a DTO a reference to the data access layer? Or should you always pass a DTO between the data access layer and the application layer?

This applies to almost all aspects of the application, including site navigation, showing/hiding certain user controls on pages, and executing custom business logic in some cases. Ho...
Best strategy to convert array output to an object?
I'm taking array output from a command-line program and parsing it into a PHP object. Consider this example of a very simple way to do this: $output = explode("\n", shell_exec(myProg)); $obj = new MyObject(); $offset_field1 = 0; $offset_field2 = 1; $obj->Field1 = $output[$offset_field1]; $obj->Field2 = $output[$offset_field2]; This ...
Tips for learning a new framework/updating an existing enterprise application -.NET
I come across several situations which involve customizing a MS framework (Ex: Built a layer above the webparts framework to utilize it in an application) or extending an existing app's functionality.

TDD: "Test Only" Methods
Looking for some practical advice here and any experiences people have had in a similar situation. We use a BDD/TDD sytle methodology for building our software (quite a large/complex application) The end result is.. behavioral specifications (Given/When/Then style) derived from business requirements, unit tests that reflect these and co...
Is there any real reason to differentiate between POST and GET when handling incoming data?
Lately I've been using a wrapper PHP class that fetches GET and POST data and lets me access it using a single getter function. After years of developing web applications I've never had a single good reason to care whether an incoming var was coming from POST or GET. Not only that but I got really sick and tired of having to check both a...

Basic question about OOP
I often have the same trouble when I have to design my class for a web application. The requirements are : - maintainable (no copy-paste for instance) - layers fully separated (the business layer doesn't have to know which method of the data layer is used) - high performance : don't load useless data. First I have a table with all my cu...
How do I build something when I know I'll get it wrong?
Background I have a personal project that I've been trying to build for around 5 years. In essence it's an online game - a web application. It's not a "money maker", just something that I really want to build, so finding the funding to hire a skilled team is very unlikely. I've built two fully-functional prototypes over the years, both...
