get site-packages folder from a python unittest -


i have standard python proj package::

proj/ ├── proj │   ├── data │   │   └── data.csv │   ├── __init__.py │   └── lib.py ├── manifest.in ├── setup.py └── tests     ├── __init__.py     └── lib_test.py

data/data.csv installed manifest.in , include_package_data key in setup.py::

~/proj$ more setup.py  setuptools import setup  setup(name='proj',        version=1.0,        packages=['proj'],        test_suite = 'tests',        include_package_data=true,        zip_safe=false)  ~/proj$ more manifest.in include proj/data/*.csv

so after python setup.py install data.csv in place want in site-packages::

$ tree ~/venv/lib/python2.7/site-packages/proj-1.0-py2.7.egg ~/venv/lib/python2.7/site-packages/proj-1.0-py2.7.egg ├── egg-info │   └── ... └── proj     ├── data     │   └── data.csv     ├── __init__.py     └── ...

in setup.py, test_suite declared, when call test proj first folder, work well::

~/proj$ python setup.py test running test ... ---------------------------------------------------------------------- ran 1 test in 0.000s ok

i use in unitest data.csv file from: ~/venv/lib/python2.7/site-packages/proj-1.0-py2.7.egg/proj/data/data.csv. in short way ~/venv/lib/python2.7/site-packages/proj-1.0-py2.7.egg/proj/data/ folder.

with code::

$ more tests/lib_test.py import unittest, os, proj proj.lib import get_data class testutils(unittest.testcase):     def test_get_data(self):         datapath = os.path.dirname(os.path.abspath(proj.__file__)) + '/data'         data = '{}/data.csv'.format(datapath)         print '\n data:', data  if __name__ == '__main__':     unittest.main()

using __file__ succed ~/sandbox/proj/proj/data/data.csv::

$ python setup.py test running test ... test_get_data (tests.lib_test.testutils) ...  data: ~/sandbox/proj/proj/data/data.csv ok ---------------------------------------------------------------------- ran 1 test in 0.000s

in fact

python setup.py test

does not load python package place python setup install put (~/venv/lib/python2.7/site-packages/proj-xxx), place python setup.py test run.

that's why with:

import proj, os os.path.abspath(proj.__file__)

we can't catch site-package folder working-copy files.

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
