``django-settings-diff`` ======================== A very simple tool to help diff two Django settings modules. Motivation ---------- Let's say that you have done some significant refactoring to your settings module. For example, you have gone from a single settings file to a modular approach, where there is no longer a single ``settings.py``. You want to make sure that your settings are effectively *exactly* the same as before, though! Of course you can't rely on simple file diffing, since there is no longer a single ``settings.py``. There are some non-intuitive things to account for, which ``django-settings-diff`` handles for you: 1. Even with a single ``settings.py``, there is a (potentially) significant difference between simply importing the file and the "final" settings that are used by Django (see https://docs.djangoproject.com/en/2.1/topics/settings/#using-settings-in-python-code). That is, we want to compare the *actual settings at runtime*! 2. The ``settings`` object cannot be naively treated as a ``dict`` -- it is similar, but different enough to prevent easy diffing (the native settings object thwarts both ``pprint`` and ``deepdiff``). So, it isn't doing anything crazy, but it removes some overhead. Installation ------------ Install from pip (recommended): :: $ pip install django-settings-diff Or, install straight from the repo: :: $ git clone https://github.com/GreenBankObservatory/django-settings-diff $ pip install django-settings-diff Note that this will install a wrapper script for you: ``diffsettings`` Entry Points ------------ Use the wrapper script (recommended): :: $ diffsettings -h Call the module: :: $ python -m django_settings_diff -h Import as library: :: $ python >>> from django_settings_diff import diffsettings >>> help(diffsettings) Usage ----- There are two standard usage patterns. You should first ensure that you have saved two versions of your settings. For this example we will use ``myapp/settings_old.py`` and ``myapp/settings_new.py``. Alternatively, you could use the same ``DJANGO_SETTINGS_MODULE`` for both dumps, but swap the settings file itself in between. This is useful in repositories that rely on the settings file being a specific name, for example. #1: Compare Python objects directly ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This uses ``deepdiff`` internally to perform the diff. Dump Settings ^^^^^^^^^^^^^ Pickle the settings modules to disk: :: $ DJANGO_SETTINGS_MODULE=myapp.settings_old diffsettings --dump old_settings.pkl $ DJANGO_SETTINGS_MODULE=myapp.settings_new diffsettings --dump new_settings.pkl Diff Settings ^^^^^^^^^^^^^ Now we can diff the two settings objects: :: $ diffsettings old_settings.pkl new_settings.pkl See the documentation for `deepdiff <https://github.com/seperman/deepdiff>`_ for help deciphering the output. #2: Compare via external diff tool ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In this method the settings are dumped as text files and then compared using a standard diff tool. Dump Settings ^^^^^^^^^^^^^ Dump the settings modules to disk (internally this uses ``pprint`` to print the settings object): :: $ DJANGO_SETTINGS_MODULE=myapp.settings_old diffsettings --dump old_settings.txt $ DJANGO_SETTINGS_MODULE=myapp.settings_new diffsettings --dump new_settings.txt Diff Settings ^^^^^^^^^^^^^ Then, use your favorite diff tool to compare these. This should work quite well, since the object hierarchy has been broken up line by line. For example: :: $ tkdiff {old,new}_settings.txt
