This error belongs to Django versions. If you want to use Django 4.* you need to find: from django.utils.translation import ugettext_lazy as _ and change to: from django.utils.translation import gettext_lazy as _ Happy Coding 🙂
swappable is an “intentionally undocumented” feature which is currently under development / in-test. It’s used to handle “I have a base abstract model which has some foreign-key relationships.” Slightly more detail is available from Django’s ticketing system and github. Because it’s a “stealth alpha” feature, it’s not guaranteed to work (for anything other than User), … Read more
In Django 1.6 and below, TEST_NAME should be a key of one of your database dictionaries. But in Django 1.7 and above, you use a TEST key which is a dictionary of settings for test databases. You probably want: DATABASES = { ‘default’:{ ‘ENGINE’:’mysql’, ‘NAME’:’testsqldb’, ‘USER’:'<username>’, ‘PASSWORD’:'<password>’, ‘TEST’: { ‘NAME’: ‘auto_tests’, } }, ‘dynamic_data’:{ ‘ENGINE’: … Read more
In my apps, I have a seperate settings.py file. In that file I have a get() function that does a look up in the projects settings.py file and if not found returns the default value. from django.conf import settings def get(key, default): return getattr(settings, key, default) APPLES = get(‘APPLES’, 1) Then where I need to … Read more
All you need to do is start a application and if its not connected it will fail. Other way you can try is on shell try following – from django.db import connections from django.db.utils import OperationalError db_conn = connections[‘default’] try: c = db_conn.cursor() except OperationalError: connected = False else: connected = True
Although I wasn’t able to come across anything Python-specific on stackoverflow, I did find a website that was helpful, and thought I’d share the solution with the rest of the community. The solution: environment variables. Note: Although environment variables are similar in both Linux/Unix/OS X and in the Windows worlds, I haven’t tested this code … Read more
I have similar problem and solved it with this answer by adding localhost to the database HOST settings in settings.py, so your database settings should look like this: DATABASES = { ‘default’:{ ‘ENGINE’:’django.db.backends.postgresql_psycopg2′, # ‘.postgresql_psycopg2’, ‘.mysql’, or ‘.oracle’ ‘NAME’:’indivo’, # Required to be non-empty string ‘USER’:’indivo’, # Required to be non-empty string ‘PASSWORD’:’ritvik’, ‘HOST’:’localhost’, # … Read more
Python modules (including Django apps) have a __file__ attribute that tells you the location of their __init__.py file on the filesystem, so import appname pth = os.path.dirname(appname.__file__) should do what you want. In usual circumstances, os.path.absname(appname.__path__[0]), but it’s possible for apps to change that if they want to import files in a weird way. (I … Read more
In newer versions of Django it is possible just by specifying INTERNAL_IPS in settings. For example: INTERNAL_IPS = ( ‘127.0.0.1’, ‘192.168.1.23’, ) and then in template just: {% if debug %} because context processors responsible for that by default, and the answers from How to check the TEMPLATE_DEBUG flag in a django template? are bit … Read more
