Redirect from one page to another by AJAX request, passing parameters with Django
I have a table in a view where according of the element Id which is clicked, that view redirect to another via Ajax request to a Django Rest Framework endpoind and render a dasboard with Chartjs, with dynamic data and sending an user_id. I make the request success and get back the results of the endpoing as json format, but when it should redirect to the other page, it redirects to an empty html template displaying the json result but without my html template. This probably is a really dummy problem, but I can't figure out the error. This answer have an useful code, but hasn't the behaviour that I need My project structure is as below: core --api --core --static --web (...and other folders) These are the routes related: core/urls.py urlpatterns = [ url(r'^socialanalyzer/recent_search_twitter/$', RecentSearchTwitterView.as_view(), name='recent_search_twitter'), url(r'^socialanalyzer/timeline_search_twitter/$', TimelineSearchTwitterView.as_view(), name='timeline_search_twitter') ] api.py/urls.py urlpatterns = [ url(r'^api/search/recent_search/user/<int:user_id>/social_network/<int:social_network_id>', SearchViewSet.as_view({'post': 'recent_search'}), name='recent_search'), url(r'^api/search/word_details/user/<int:user_id>/social_network/<int:social_network_id>/word/<string:word>', SearchViewSet.as_view({'post': 'word_details'}), name='word_details') ] So in my web/views.py, i need to navigate from: RecentSearchTwitterView (recent_search_twitter.html) to TimelineSearchTwitterView (word_searched_details_twitter.html) In that sense, in recent_search_twitter.html I have a table with each row as below: <td><a href="" onclick='wordSearchedDetail("{{key.word}}")'><b>{{key.word}}</b></a></td> That call to wordSearchedDetail where is in: static/js/custom.js function wordSearchedDetail(word){ $.ajax({ url:'/socialanalyzer/timeline_search_twitter/', type: 'GET', data: … -

Is converting timestamp to datetime in django will convert datetime by default to datetime in UTC
I am creating an app which will use peoples from different timezones. I have a model class Fixture(models.Model): fixture_id =models.IntegerField(primary_key=True) event_date = models.DateTimeField(null=True) I want while creating objects from this model that event_date field save datetime object in UTC to convert it in user's timezone while show him this data in front-end. In django documentation i read that When support for time zones is enabled, Django stores datetime information in UTC in the database, uses time-zone-aware datetime objects internally, and translates them to the end user’s time zone in templates and forms. Now i am creating an object b = Fixture.objects.create(fixture_id = fixture, event_date = datetime.datetime.fromtimestamp(variable_contained_timestamp)) Is according django documentation in event_date field will be stored datetime object in UTC not in datetime object with my database time zone -

Updating to non-standard database in DRF
Using Django Rest Framework, how to execute update/PUT calls to a non-standard database? In my Django project I'm using a separate database for the application data: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), }, 'bookstore': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'bookstore.sqlite3'), } } I use the ModelSerializer and ModelViewSet to automatically create the API for me. I loop over the models to automatically generate all the Serializers and ViewSets (quite a big number of tables), the generated classes end up looking like this: ModelSerializer: class BookSerializer(serializers.ModelSerializer): class Meta: model = Book fields = '__all__' ModelViewSet: class BookViewSet(viewsets.ModelViewSet): queryset = Book.objects.using('bookstore').all() serializer_class = BookSerializer I needed to add the using('bookstore') here to make this work. Reading (GET) works fine. When I try to do a PUT update, I get a no such table: book Sqlite error. It seems like the update isn't routed to the bookstore database. For completeness, I use these loops to generate the ModelSerializer and ModelViewSets from the models: ModelSerializer, generator: models = dict(apps.all_models['api']) for name, model in models.items(): class_name = name[:1].upper() + name[1:] + 'Serializer' Meta = type('Meta', (object, ), {'model': model, 'fields': '__all__'}) print(class_name) globals()[class_name] = type(class_name, (serializers.ModelSerializer,), {'Meta':Meta, }) ModelViewSet, generator: models … -

how to set username to python request explicitly
Trying to set token and username to python request.get session, so that next consecutive session.post must have both the session and username.

Django How can I unittest a wait function for db written in bash script when using dockerized database service?
After searching stackoverflow for a while, I found plenty of ways to check if dockerized database service is ready before connection. So I include both of them here. first one is written in bash script and I found it in here if [ "$DATABASE" = "postgres" ] then echo "Waiting for postgres..." while ! nc -z $SQL_HOST $SQL_PORT; do sleep 0.1 done echo "PostgreSQL started" fi python manage.py flush --no-input python manage.py migrate exec "$@" The second one is written in python and I found it in here: class Command(BaseCommand): """Django command that waits for database to be available""" def handle(self, *args, **options): """Handle the command""" self.stdout.write('Waiting for database...') db_conn = None while not db_conn: try: connection.ensure_connection() db_conn = True except OperationalError: self.stdout.write('Database unavailable, waiting 1 second...') time.sleep(1) self.stdout.write(self.style.SUCCESS('Database available!')) I use this docker command ENTRYPOINT ["/usr/src/app/entrypoint.sh"] to run the first one. I know how to write unit tests for the second one, because it's in python. But can anyone help me find a way to write tests for the first one? In addition, Can anybody name what are the drawbacks and advantages of each method and also if there exists some other important considerations for writing such function? Thanks -
