Inconsistent site.py behavior between venv and system
by Demian Brecht April 30, 2018

April 30, 2018

I recently ran into an issue using the site package and I wanted to confirm that I'm not doing something wrong here before creating an issue: I have a need to `git subtree` modules into a Django project and then add the dependencies such that they're discoverable in code. I also need to have consistent behavior between `python setup.py (develop|install)` and `pip install -r requirements.txt` (the latter is used by Heroku for project installation). An example project that demonstrates the issue is here: https://github.com/demianbrecht/python-sitehooks-example. In the example, I've subtree'd requests into _vendor and forced site hooks to fire using `site.main()` in testme/settings.py: https://github.com/demianbrecht/python-sitehooks-example/commit/1b81e15c6f2…. Forcing the execution is not needed when the package is actually installed using setup.py, but is needed when using `pip install -r requirements.txt`. This works great when running within a virtualenv, but I get the following on system python: $ python3.6 ./manage.py test Traceback (most recent call last): File "./manage.py", line 22, in <module> execute_from_command_line(sys.argv) File "/usr/local/lib/python3.6/site-packages/django/core/management/__init__.py", line 364, in execute_from_command_line utility.execute() File "/usr/local/lib/python3.6/site-packages/django/core/management/__init__.py", line 308, in execute settings.INSTALLED_APPS File "/usr/local/lib/python3.6/site-packages/django/conf/__init__.py", line 56, in __getattr__ self._setup(name) File "/usr/local/lib/python3.6/site-packages/django/conf/__init__.py", line 41, in _setup self._wrapped = Settings(settings_module) File "/usr/local/lib/python3.6/site-packages/django/conf/__init__.py", line 110, in __init__ mod = importlib.import_module(self.SETTINGS_MODULE) File "/usr/local/lib/python3.6/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 978, in _gcd_import File "<frozen importlib._bootstrap>", line 961, in _find_and_load File "<frozen importlib._bootstrap>", line 950, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 655, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 678, in exec_module File "<frozen importlib._bootstrap>", line 205, in _call_with_frames_removed File "/<path>/<to>/testme/testme/settings.py", line 13, in <module> site.main() File "/usr/local/lib/python3.6/site.py", line 525, in main abs_paths() File "/usr/local/lib/python3.6/site.py", line 110, in abs_paths m.__cached__ = os.path.abspath(m.__cached__) File "/usr/local/lib/python3.6/posixpath.py", line 369, in abspath path = os.fspath(path) TypeError: expected str, bytes or os.PathLike object, not NoneType Using venv and system comparisons for debugging doesn't help much as site.py is different in the two environments. Any insight into what may be going on here or what I'm doing wrong would be much appreciated. I realize that I could just muck with PYTHONPATH, but I thought this approach would be a little nicer as it's transparent to the user. ------- GPG Fingerprint: 9ACFB014BA1E5B4939ACA3B214E4E96742F22903

Flask test generator code review?
by Albert-Jan Roskam April 30, 2018

April 30, 2018

Hi, I am writing my first unittests for a Flask app. First modest goal is to test whether a selected subset of the templates return the expected status 200. I am using a nose test generator in a class for this. Is the code below the correct way to do this? And is there a way to dynamically set the docstring of test_generator? This would make the nosetests output a bit more understandable. Thanks! Albert-Jan import os import sys from os.path import splitext from http import HTTPStatus as status import nose from MyFabulousApp import app app.testing = True template_folder = app.config['TEMPLATE_FOLDER'] class Test_MyFabulousApp_HTTP_Status_OK: def __init__(self): self.setup() # with unittest, setUp is called automatically, but not with nose def setup(self): self.client = app.test_client() self.client.post('/login', follow_redirects=True) def teardown(self): self.client.post('/logout', follow_redirects=True) def test_generator(self): """Does template return HTTP Status 200?""" def the_test(self, template): # the following line throws an error: AttributeError: attribute '__doc__' of 'method' objects is not writable #self.test_generator.__doc__ = 'Does template "%s" return HTTP Status 200?' % template respons = self.client.get('/' + template) actual = respons.status_code desired = status.OK.value assert actual == desired, \ 'Template "%s" returns status code %d' % (template, actual) templates = [splitext(item)[0] for item in os.listdir(template_folder)] for template in templates: yield the_test, self, template if __name__ == '__main__': nose.run(defaultTest=__name__, argv=[sys.argv[0], '__main__', '--verbosity=2'])

unittest.Testsuite and execution order
by Francesco Russo April 30, 2018

April 30, 2018

Hello! I'm reading the documentation of unittest.TestSuite (Python 2 and 3), but I can't find any explicit sentence stating that TestSuite will honor the order. I can only read that TestSuite can group test cases together. Please blame it on my poor English skills if I'm not interpreting the documentation correctly. My use case: my SUT is split into modules. Besides writing unit tests for each module, I want to write an integration test, and I also need to perform some actions between two calls to the SUT. In my case, the order of the execution is important. Now, the current implementation of TestSuite uses a list, internally, so, today, the order is honored if I create a TestSuite calling addTest() in the proper order, or if I pass a list to the constructor. I've seen examples like this: class MyTestCode(unittest.TestCase): def test_func_1(self): # do something to test func_1 on the SUT sut.func_1() self.assert(...) def perform_intermediate_step(self): # do something between func_1 and func_2 def test_func_2(self): # do something to test func_2 on the SUT sut.func_2() self.assert(...) suite = unittest.TestSuite() suite.addTest(MyTestCode("test_func_1")) suite.addTest(MyTestCode("perform_intermediate_step")) suite.addTest(MyTestCode("test_func_2")) Such an example works, today, since TestSuite uses a list, and addTest() appends to the list. My question is: is this something that I can rely on for the future? I definitely don't want to rely on the current implementation, unless I see it in the documentation. If it's something that I can't rely on for the future, then I'd rather write my test code in a different way. Regards, Francesco P.S.: I strongly believe that there are better ways to implement a test like the one I just described, but what I'm interested in now is whether TestSuite is meant to be future-proof for such a case. -- Francesco Russo The White Rabbit put on his spectacles. 'Where shall I begin, please your Majesty?' he asked. 'Begin at the beginning,' the King said gravely, 'and go on till you come to the end: then stop.'

Re: jilian to Gregorian date conversion error
by sum abiut April 29, 2018

April 29, 2018

Hi Dennnis, Thank you for your email. My issue is i what to be able to display the rage of date base on the start and end date that was selected but i don't know how to do that. when i did a for look from my template for example. {%for a in result_proxy%} <td>{{a.date_applied}}</td> {%endfor%} i was able to display the range of dates but its is julian date but i don't want the dates to be in julian dates. I want the dates to be in a gregorian date where by the end users can understand it. Which is why i was trying to convert that from my view.py before passing the the parameter to the template. appreciate any assistances. cheers, On Sun, Apr 29, 2018 at 2:39 AM, Dennis Lee Bieber <wlfraed(a)ix.netcom.com> wrote: > On Thu, 26 Apr 2018 15:43:43 +1100, sum abiut <suabiut(a)gmail.com> > declaimed > the following: > > >ok so i have fixed that using the for loop > > > >result_proxy=connection.execute(stmt).fetchall() > > for a in result_proxy: > > test=datetime.date.fromordinal(int(a.date_applied)) > > > > > >Now if i want to pass a range of date to date_applied above.

Understanding pdb result
by Rich Shepard April 28, 2018

April 28, 2018

Running python3-3.6.5 and wxPython-4.0.1 on Slackware-14.2. The module begins this way: #!/usr/bin/env python3 import sys, os import pdb import wx When pdb is invoked and I step through the code I get these results: $ python3 -m pdb openEDMS.py > /home/rshepard/development/openEDMS/openEDMS.py(8)<module>() -> """ (Pdb) s > /home/rshepard/development/openEDMS/openEDMS.py(10)<module>() -> import sys, os (Pdb) s > /home/rshepard/development/openEDMS/openEDMS.py(11)<module>() -> import pdb (Pdb) > /home/rshepard/development/openEDMS/openEDMS.py(12)<module>() -> import wx (Pdb) --Call-- > <frozen importlib._bootstrap>(966)_find_and_load() (Pdb) My web search suggests that I need to import importlib, but doing so does not change the results. Please pass me a pointer to a resource that teaches me how to avoid this error. TIA, Rich
