URLs management between React and Django
I have a Django application with following URLs patterns: urlpatterns = [ path('', include('tsangom.urls')), path('admin/', admin.site.urls), path(API_ROOT, include('tsangod.urls')), path('app/', include('tsangof.urls')), path('accounts/', include('django.contrib.auth.urls')), ] The /app path is served by a React app with URLs managed by a React Router. When I navigate inside the React app, i.e. by clicking on menus, everything is fine. I stay in the React App. However, if I enter a URL in the browser like /app/view, then Django is taking over URLs management and not able to route to the appropriate URL in React Router... this is normal. However, my question is what would be your recommendation to overcome this issue? How can I define the URLs in Django to handshake with the React App at the requested URL? Should I also modify the React App for that? I would prefer avoiding to define again the URLs of the React Router inside Django. -
dry_yasg example on request_body
So I use dry_yasg library to produce swagger schema. Is any way to give request_body with example json? It will make anyone can copy-paste example request body with minimal edit. My code right now: @swagger_auto_schema(operation_summary='Onboarding', operation_description='Onboarding new merchant', security=[{'Bearer': []}], request_body=serializers.OnboardingSerializer, responses={201: openapi.Response( schema=serializers.OnboardingResponseSuccessSerializer, description='Created', examples=swagger_example('hedwig_proxy/v2', '201_created')), 403: openapi.Response( schema=serializers.OnboardingResponseErrorSerializer, description='Forbidden', examples=swagger_example('hedwig_proxy/v2', '403_forbidden')), 409: openapi.Response( schema=serializers.OnboardingResponseErrorSerializer, description='Conflict', examples=swagger_example('hedwig_proxy/v2', '409_conflict')), 422: openapi.Response( schema=serializers.OnboardingResponseErrorSerializer, description='Unprocessable Entity', examples=swagger_example('hedwig_proxy/v2', '422_validation')), 500: openapi.Response( schema=serializers.OnboardingResponseErrorSerializer, description='Internal Server Error', examples=swagger_example('hedwig_proxy/v2', '500_internal_server')) }) -
Django autocomplete_fields for multiple fields in same form
This are my models: class Person(models.Model): first_name = models.CharField('Name', max_length=200) family_name = models.ForeignKey(Family, on_delete=models.PROTECT) gender_is_male = models.BooleanField(default=True) class Child(models.Model): person = models.OneToOneField(Person, on_delete=models.CASCADE, primary_key=True) father = models.ForeignKey(Person, on_delete=models.CASCADE, related_name='father_of', limit_choices_to={'gender_is_male': True}) mother = models.ForeignKey(Person, on_delete=models.CASCADE, related_name='mother_of', limit_choices_to={'gender_is_male': False}) In my admin I have the following: class ChildForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(ChildForm, self).__init__(*args, **kwargs) self.fields['person'].queryset = Person.objects.filter( Q(child__isnull=True) | Q(child=self.instance) ) self.fields['father'].queryset = Person.objects.filter(husband_of__isnull=False).distinct() self.fields['mother'].queryset = Person.objects.filter(wife_of__isnull=False).distinct() class ChildAdmin(admin.ModelAdmin): form = ChildForm list_per_page=50 search_fields=('person__first_name','person__family_name__family_name') Separate querysets looking up the same Person table provide the option lists for the ChildForm in Django Admin. When the querysets got bigger, I tried to use the 'autocomplete_fields' option: In PersonAdmin I added: search_fields=('first_name','family_name__family_name') In ChildAdmin I added: autocomplete_fields = ['person', 'father', 'mother'] The autocomplete function is working OK, but now, the option lists for all the three autocomplete fields are the same, and has all Persons. This appears to run contrary to my motive of having the autocompletes, viz. to limit the queryset sizes. For eg. why should the options for person contain those who are already children? How can the lists be limited for each of the fields according to the querysets in ChildForm? -
No images on heroku after deployment (django) (using AWS)
I deployed my app on heroku and instead of letting collect images from my system folder, I used AWS's S3 bucket. None of the images are displayed nor the background image. Even the django admin page is displayed with only username and password fields only like a normal form with no effects. I guess there is some problem with path setting in settings.py What are changes I need to do make it work. You can have look at the current website at https://market-shaurya.herokuapp.com/ settings.py file import os # Build paths inside the project like this: os.path.join(BASE_DIR, ...)

Django backend configuration to Stripe, React frontend

Combination of Django with urllib
I have a Django Application. Now, in a particular scenario I make a POST request(/doSomeWork) from template and come to the view. Inside the view, I open an url using urllib.request.urlopen() and work on it's response. Then, finally I return back to the template. So, my view function somewhat look like, def doSomeWork(request): ------ Some Tasks Performed ------ response = urllib.request.urlopen("http://xx.yy.com/XYZ") content = response.read() ------ Do Some More Tasks -------- return HttpResponse(***) Now, the problem it creates is that, it is automatically making multiple calls to the /doSomeWork. So, the function doSomeWork(request) is being called several times. As per my idea this urlopen is somehow messing with the normal Django flow. Can anyone have any idea regarding the problem or possible wayouts ? -
Django custom view stopped working after updating to 2.2 from 1.1
Backstory: I took over a website from two guys who wanted to abandon it due to financial reasons, but their only client didn't want to change their system, so I took on the job to maintain it. I updated to Django 2.2 from 1.1 and it seemed to work flawlessly, but a specific view stopped working and returns Internal Server Error (500). I have troubleshooted for hours and found the core issue is in the ScheduleView. If I change the view to a Django premade view, it works. What do I miss? ScheduleView class class ScheduleView(TherapistRequiredMixin, SuccessMessageMixin, FormView): form_class = ScheduleForm template_name = "schedule.html" success_message = "Nya bokningstillfällen är skapade" def get_success_url(self): return reverse('schedule') def form_valid(self, form): ret = form.save() if ret: messages.error(self.request, ret) # return super(ScheduleView, self).form_invalid(form) return super().form_invalid(form) else: # return super(ScheduleView, self).form_valid(form) return super().form_valid(form) -
How does gmail android app loads external images in a mail?
I am creating a mailtracker service in python which generates a transparent pixel which the user can copy to his email and send it. Actually due to google image proxy the image is not refetched from original server every time,So I came up with a workaround where i am returning an invalid response whenever the pixel is requested from my server making gmail to refetch it everytime. Everything is working fine on gmail web app but gmail app for android shows some weird behaviour. Whenever an other email which is just above or below the email having the transparent pixel is opened my server gets a request even though the email having the pixel is not opened. I am unable to figure out why is this happening. -
Django queryset union from different models and OnetoOne keys

How can I output the name linked to the def __str__(self): method? Moreover, as you can see, a Profile (solo_performer) can … -

Search javascript in Django
I have the following javascript code to do a search (search with a button in the bar) on a page in Django 2.2, it works but it highlights it for less than 1 second, that is, it finds the word highlights it and no longer highlights it anymore As I said it does less than 1 second and the idea is that it is checked and if possible that it continues showing other coincidences like CTRL + F does in browsers. Can someone help me with a code that does work well?

Django compressor and Cloudfront
I use AWS S3 to store my Django static files (using django-storages). And alternate cloudfront domain name to serve these files. I am unable to finish Django compressor via python manage.py compress. This is the error I see: CommandError: An error occurred during rendering /home/ubuntu/foldername/templates/home/xxx.html: 'https://xxx.domainname.com/static/plugins/xxx-xxx/xxx.js' isn't accessible via COMPRESS_URL ('https://s3bucket-static.s3.amazonaws.com/') and can't be compressed So I tried using the default cloudfront address, alternate domain name and S3 bucket for COMPRESS_URL: https://s3bucket-static.s3.amazonaws.com/ https://s3bucket-static.s3.amazonaws.com/static/ https://d1231232131241123.cloudfront.net/ https://d1231232131241123.cloudfront.net/static/ https://xxx.domainname.com/ https://xxx.domainname.com/static/ Only https://domainname.com/static/ don't have error.
