Setuptools' ``include_package_data`` option does not work

MANIFEST.in not honoured during install phase

The python package setup procedure appears to be a mess, you have setuptools, distutils, and distribute (distutils2?). All I set out to do was to fix the installation setup.py in django-simplemenu package which was omitting the non-python module plain locale directory but instead got myself involved a 3 hour roller coaster; I am sharing my findings in hopes of helping you, so if you are reading this do +1 this.

Including sub directories and non python files as part of package

There are two ways: MANIFEST.in file and package_data setup.py option. The latter is Pythonic but doesn’t do recursive includes - so you would have to list every sub directory - and can not include files in the root top most folder; sure once could write a python function to do this but why the complexity? MANIFEST.in with its file/directory pattern matching and with the setup.py's ``include_package_data`` option fits the bill:

``include_package_data``
    If set to ``True``, this tells ``setuptools`` to automatically include any
    data files it finds inside your package directories, that are either under
    CVS or Subversion control, or which are specified by your ``MANIFEST.in``
    file.  For more information, see the section below on `Including Data
    Files`_.

The problem is that does not work, files specified in MAIFEST.in weren't being copied during install. After searching and trial an error the solution was to use distribute (or distools) instead of the old setuptools package. So if you are having issues import distuitls rather then setuptools.

My django-simplemenu setup.py

from setuptools import setup, find_packages 
   # your system should use distribute which is successor to setuptools 
   # and distutils, http://stackoverflow.com/questions/6344076/differences-
   # between-distribute-distutils-and-setuptools
   # 'distribute' imports itself as 'setuptools'
package = __import__('simplemenu')

setup(name='django-simplemenu',
    install_requires=['distribute'], # let's require the enhanced setuptools
    version=package.get_version(),
    url='http://github.com/danielsokolowski/django-simplemenu',
    license='BSD',
    description=package.__doc__.strip(),
    author='Alex Vasi , Justin Steward , Daniel Sokolowski ',
    author_email='unemelpmis-ognajd@danols.com',
    include_package_data=True, # this will use MANIFEST.in during install where we specify additional files
    packages=find_packages(),
    # Below is not needed as we are utilizing MANIFEST.in 
    #package_data={'simplemenu': ['locale/en/LC_MESSAGES/*', 
    #                             'locale/ru/LC_MESSAGES/*']
    #              },
    scripts=[],
    requires=[],
    )

My django-simplemenu MANIFEST.in

include LICENSE
include README.rst
recursive-include simplemenu *.py
recursive-include simplemenu/locale *
prune simplemenu/migrations

How to child proof a fireplace

DIY - Do it yourself fireplace child guard Our wonderful 8.5 month old Sofia has become a crawling race car with an untamed thirst for exploration. And so with the cold nights approaching we needed to child proof the fireplace. This however proved to be more difficult than would reasonably expect, I've checked the local Toys "R" Us, Walmart, and even a Canadian Tire with no success for a ready to use product. Internet search was more fruitful and returned a few online stores one could order from, however in all honestly they didn't look too sturdy to me. So I build my own relatively quickly and inexpensively. Materials needed is a privacy plastic lattice - the smallest hole pattern - a few screws and anchors; tools needed are a drill, and a handsaw if you don't have the lattice cut at the store - that’s it. The construction consits of screwing the lattice into the wall and the final product is easiest explained through following pictures. Feel free to +1 this po…

Duplicate value found: duplicates value on record with id: <unknown>.

System.DmlException: Insert failed. First exception on row 0; first error: DUPLICATE_VALUE, duplicate value found: <unknown> duplicates value on record with id: <unknown>.The above error is triggered in the database layer and caused by a trigger or workflow outside of your main code of block that is bubbling this exception. This is rather difficult to track down especially if you are unfamiliar with the code, I am sharing my procedure in the hopes this saves you time - if you find this helpful drop me a line or follow me on twitter @danielsokolows. This error is caused by unique field constraint on the object, so the first step is to examine the object and locate the API names of all unique fieds. You can do this through SF direclty 'Setup < Customize &lt <object being inserted> &lt Fields' or by downloading the `src/objects` metadata information and searching for <unique>; I preffer the latter and actually download ALL matadata information f…
