Why subclassing AppConfig is required in Django
From Django official docs, it reads: It is important to understand that a Django application is a set of code that interacts with various parts of the framework. There’s no such thing as an Application object. However, there’s a few places where Django needs to interact with installed applications, mainly for configuration and also for introspection. That’s why the application registry maintains metadata in an AppConfig instance for each installed application. Above means subclassing AppConfig is for maintaining metadata, which is used for configuration and also for introspection. Q1: Apart from labeling in Django Admin portal, I did not see any other use cases. any other examples for configuration and also for introspection ? Below posts did not help me out. What is the purpose of apps.py in Django 1.9? How is Django apps.py supposed to be used? -

How to set value of DateTime field automatically in Django REST Framework HTML form?
I have a very basic Django Model and use it in Django REST Framework. When using the browsable API tool and requesting an instance of a ressource, I can set the values of the different attributes using the HTML form at the bottom of the page. All attributes have their current value pre-set except for the DateTime fields. Is there a special setting required such that the form fields for DateTime entries field are prefilled with their current value? -

python-social-auth return drf token as a parameter
I am using django rest framework's token authentication for my clients. I have also implemented social auth using python-social-auth in my project. However, once the user has logged in (or signed up) using python social auth, I want to redirect to the next url along with the drf token as a parameter. So, if I make a request like this from the frontend: localhost:8000/auth/login/github?next=localhost:3000 then the backend should redirect to the following url localhost:3000?token=USER_TOKEN_HERE the USER_TOKEN would be the drf token for the user who was created or logged in. How can this be implemented in python-social-auth? I couldn't find any good references. Thanks a lot! -

I working on the project where I need chart. I tries to use chart.js but something went wrong. I have list of indicators with target and progress for each. I want to display this list of indicators and their corresponding target and progress. Below is the code I am using and the output. How can I modify the codes to display the full chart with bars. def chart(request): dataset = Indicators.objects.values('indicator','target','progress') indicator = list() target = list() progress = list() for entry in dataset: indicator.append(entry['indicator']) target.append(entry['target']) progress.append(entry['progress']) target_series = { 'name': 'Target', 'data': target, 'color': 'blue', } progress_series = { 'name': 'Progress', 'data': progress, 'color': 'red' } chart = { 'chart': {'type': 'column'}, 'title': {'text': 'Indicator Analysis'}, 'xAxis': {'categories': indicator}, 'series': [target_series,progress_series] } dump = json.dumps(chart) return render(request,'staff/analysis.html',{"chart":dump}) Output of the above codes -
SocialApp matching query does not exist error with an actual domain
I'm trying to add a Google Login to my Django application by using the django-allauth library. It worked fine on my localhost. However, when I try to test it with a domain, it gives SocialApp matching query does not exist error. I have tried to change the SITE_ID, also I have tried to delete the site and insert again. When I run the code below, it returns 4. from django.contrib.sites.models import Site Site.objects.get(domain='www.subdomain.mysite.com') So my SITE_ID is 4 and I have already added the site to the socialapp_sites table. How can I fix this issue? -
Django - How to handle DateTime field as primary key
I have a class with a DateTime as primary key defined class GrowEntry(models.Model): dateTime = models.DateTimeField(primary_key=True, unique=True, null=False, blank=False) airTemperature = models.FloatField(null=True, blank=True) airHumidity = models.FloatField(null=True, blank=True) def __str__(self): return "time {datetime}T:{airtemp}H:{airHumidity}".format(datetime = self.dateTime, airtemp = self.airTemperature, airHumidity = self.airHumidity) def get_absolute_url(self): return reverse('growentry_edit', kwargs={'pk': self.pk}) def get_formatted_id(self): return self.dateTime.strftime("%Y-%m-%d %H:%M:%S") It works, but in Admin I noticed I can't delete entries because the default method (or action, whatever it is) try to use the DateTime field as parameter with the long date format. To solve this I have overridden the Admin this way @admin.action(description='Delete entry') def delete_model(modeladmin, request, queryset): if not modeladmin.has_delete_permission(request): raise PermissionDenied for obj in queryset: obj.delete() class GrowEntryAdmin(admin.ModelAdmin): list_display = ['dateTime', 'airTemperature', 'airHumidity'] ordering = ['dateTime'] actions = [delete_model] but now I have two actions in the list (the default one and my custom). I think I am missing something. There is some guideline about this? How can I get rid of the default action? -
Django: Subtract the time from two datetime objects
I need to subtract two times and get the number of minutes between them to the nearest minutes. For the scheduled_time, it has become in string and im not able to convert it back to time present_time = timezone.now().time() print(present_time) //output is -> 10:36:01.847822 scheduled_time = datetime.strftime(test.scheduled_date_time, '%H:%M:%S') //output is -> 10:20:52 in string format print(scheduled_time) How do I subtract both and get the result to the nearest minutes? :(
