Error while confirm by the mail
TemplateResponseMixin requires either a definition of 'template_name' or an implementation of 'get_template_names()' Url: from allauth.account.views import confirm_email as allauthemailconfirmation url(r'^rest-auth/', include('rest_auth.urls')), url(r'^rest-auth/registration/account-confirm-email/(?P<key>\w+)/$', allauthemailconfirmation, name="account_confirm_email"), url(r'^rest-auth/registration/', include('rest_auth.registration.urls')), I just read about this, but I don't understand how to modify my code -
Jinja range raises TemplateSyntaxError in Django view
In a django jinja2 tempate with the code {% for i in range(10) %} foo {{ i }}<br> {% endfor %} a TemplateSyntaxError is raised with the error message Could not parse the remainder: '(10)' from 'range(10)' What do I need to do in order to loop over a range in a jinja2 template. I found a link in the django documentation explaining that Because Django intentionally limits the amount of logic processing available in the template language, it is not possible to pass arguments to method calls accessed from within templates. Data should be calculated in views, then passed to templates for display. but I don't think that this applies to the range function. -

Error when using argparse in django project
Firstly, I wrote python code to solve my own problem, it was fine and I saved in Test.py file. A peace in this code, i use google API code at: https://developers.google.com/gmail/api/quickstart/python. You can see at quickstart.py at Step 3 in that page. Now, I must write a RestAPI webservice for this code. I'm using django rest framework to do it. I follow this example: http://agiliq.com/blog/2014/12/building-a-restful-api-with-django-rest-framework/. I run it successful. Now, I copy Test.py into this project to combine its. I just import it to views.py and don't use anything to write in views.py. Now I run again and get an error in local server: File "/../Desktop/rest_example/restapp/urls.py", line 3, in <module> from . import views File "/../Desktop/rest_example/restapp/views.py", line 7, in <module> from .Test import workWithGmail File "/../Desktop/rest_example/restapp/Test.py", line 26, in <module> flags = argparse.ArgumentParser(parents=[tools.argparser]).parse_args() File "/usr/lib/python3.5/argparse.py", line 1738, in parse_args self.error(msg % ' '.join(argv)) File "/usr/lib/python3.5/argparse.py", line 2394, in error self.exit(2, _('%(prog)s: error: %(message)s\n') % args) File "/usr/lib/python3.5/argparse.py", line 2381, in exit _sys.exit(status) SystemExit: 2 and this error in client: A server error occurred.

Using django and redmine together on the same server
I'm searching for a way to configure apache correctly so that my django user can add bug in redmine without setting up multiple server. I have two half working apache configuration : The classic one : WSGIScriptAlias / /home/my_project/settings/wsgi.py The django server can run, but if I try to call a redmine url, it makes an error 404. And I tried to use a regex to protect the Redmine url pattern from Django : WSGIScriptAlias ^\/(?!redmine(.*)) /home/my_project/settings/wsgi.py For this one Redmine works, but I get the default apache page as if the configuration was'nt done for all the Django URL. Is there something wrong with my regex ? Is this the wrong approach to this problem ? Any idea ? -

Logging exceptions in Django commands
I have implemented custom commands in Django, and their exceptions aren't logged in my log file. I created an application my_app_with_commands which contains a directory management/commands in which I implemented some commands. A sample command, could be like this, which crashed due to an exception: import logging from django.core.management.base import BaseCommand class Command(BaseCommand): help = 'Do something usful' log = logging.getLogger(__name__) def handle(self, *args, **options): self.log.info('Starting...') raise RuntimeError('Something bad happened') self.log.info('Done.') And my logging configuration is like this: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'normal': { 'format': '%(asctime)s %(module)s %(levelname)s %(message)s', } }, 'handlers': { 'file': { 'level': 'INFO', 'class': 'logging.FileHandler', 'filename': os.path.join(BASE_DIR, '..', 'logs', 'my_log.log'), 'formatter': 'normal', }, 'mail_admins': { 'level': 'ERROR', 'class': 'django.utils.log.AdminEmailHandler', 'include_html': True, } }, 'loggers': { 'django': { 'handlers': ['file'], 'level': 'INFO', 'propagate': True, }, 'my_app_with_commands': { 'handlers': ['file', 'mail_admins'], 'level': 'INFO', 'propagate': True, }, }, } When I run the command, the calls to the logger are successfully saved to my_log.log file: 2016-09-22 11:37:01,514 test INFO Starting...

Django selenium test hanging between tests
I can't figure out why my django selenium tests are so slow. I have been working on test speed improvement in a Django application. I have written a number of Selenium tests but they have dramatically slowed down test turnaround time, with each selenium test taking approximately 25-40 seconds. I have been reading a lot about selenium test speed up and the vast majority of speed improvements are already implemented: PhantomJS headless browser, explicit waits, browser reuse between tests, find by css selector and atomic tests I have added some timers to understand where the time is lost and I was surprised to find out that setUp takes on average 1.3s, teardown takes 0.001s and the entire test function from beginning to end ranges between 1s and 4s. test_xyz(research.tests.abcde) ... /home/userxyz/.virtualenvs/xyz/local/lib/python2.7/site-packages/requests/packages/urllib3/connectionpool.py:734: InsecureRequestWarning: Unverified HTTPS request is being made.

Django Rest framework JWT with custom model and fields
I am using Django Rest framework JWT. My problem is that I have to generate token based on other model rather than auth_user.

Is there a way to avoid default database setting in Django project ?
According to Django we can keep default database as empty dictionary {} but when we run it , raises Improperly configured database settings. I have used automated routers in my app files and registered them on settings.py . Django cannot avoid default database . Even when we define multiple databases with default db , Django will search for queries in default database and gives error table not found in default database. Adding auth_db for auth routers bad idea cause I have 2 apps and 2 databases in one project file . Thanks in Advance :) #hope -
Django Restul return absolute URL's
So I have a fairly straight forward serializer class ScheduleSerializer(serializers.ModelSerializer): class Meta: model = FrozenSchedule fields = ['startDate', 'endDate', 'client', 'url'] startDate = serializers.DateField(source='start_date') endDate = serializers.DateField(source='end_date') client = serializers.StringRelatedField(many=False) url = serializers.URLField(source='get_absolute_url') And it's related ViewSet class ScheduleViewSet(viewsets.ReadOnlyModelViewSet): queryset = FrozenSchedule.objects.not_abandoned().future()\ .filter(signed=False).order_by('start_date') serializer_class = serializers.ScheduleSerializer It returns JSON which looks like this: [ { "startDate": "2016-10-01", "endDate": null, "client": "Abscissa.Com Limited", "url": "/clients/abscissac/frozenschedule/1", } ] But I'd like it to return the complete URL, not just the relative path [ { "startDate": "2016-10-01", "endDate": null, "client": "Abscissa.Com Limited", "url": "http://localhost:8000/clients/abscissac/frozenschedule/1", } ] Could I serialize URL's this way inside my Serializer?

But it requires the request object to build the UR http://www.django-rest-framework.org/api-guide/reverse/ -
