One major area that the author did not cover: Modules. The idea of 'Gems' in Rails(ruby) are exceptionally well engineered. Many powerful tools can be added by simply including a Gem. On the Django side I have found the situation to be much worse. Many 'Apps' are hard to integrate and often it is easier to rewrite simple things than trying to customize them. This is what caused me to switch to Rails after a year with Django

This has been a frustration of mine as well. In the Convention over Configuration mindset, there doesn't seem to be a "best" convention for Django apps. You can install a django package easily through pip, but then does it need urls added, middleware, or signals added in your settings.py? The amount and quality of integration docs provided depends from package to package.

I think there are advantages to each. Rubygems combined with bundler is an excellent way to package up functionality, specifiy dependencies and have things play together nicely. pip + virutalenv is similar, but not quite as good at this part - but python having module namespaces makes it far easier to write packages which you can be sure wont stomp all over each other.

  I'm dipping into both Rails and a Python project right now (non-Django), both for the first time, and had difficulty "listing required packages to go along the source" in Python. In Rails/Ruby I can use Bundler: git clone bundle install [do development] I'd like to do the same for a python project: git clone _something_ install_my_dependencies [do development] I looked into pip, but it seems I have to package my src into a Python module and install that. setup.py doesn't make sense for my project since it's not a module meant for redistribution. I intend to use py2exe. Basically I just need a way to install dependencies for development. foreach thing in file pip install thing is the best that I can come up with. This is admittedly not terrible, but I feel like there is a better way and I just don't know about it.

    There is a better way! A virtualenv combined with pip and a project requirements[1] file is the best way to handle this. It even supports SVN/SSH checkouts and .egg distributed packages.

      Can I use pip to just install the dependencies without packaging my project as a module? I understand that pip installs "my module" to site packages or a directory under virtualenv. This is not what I need. I don't have a "my module" to install. I just need to make sure that the dependencies are installed on the machine/virtualenv that I'm using for development. I studied the requirement file documentation and I couldn't find a solution. It seems that to take advantage of this feature in pip I have to write a setup.py, and as I've mentioned that really doesn't make sense for my type of project. Or am I misunderstanding something?

        pip freeze > requirements.txt pip install -f requirements.txt Now whenever you go to develop, pip install -f requirements.txt, when you update dependent packages, pip freeze. You are by no means required to make your source code a module or anything like that. If you use the above with a virtualenv you can isolate different models for different projects and have them frozen at different versions. You are also able to modify requirements.txt to include version specific information. packagename==3.4.0 now locks packagename to 3.4.0 when pip goes to install it. I'm assuming your git directory looks like this: $DIR \ | - requirements.txt | - fileone.py | - filetwo.py | - folder \ | - __init__.py | - filethree.py I have several projects set up exactly like that, especially since they will never have to be distributed using a .egg or anything else.

        This is exactly what I need. Thank you!
