How can I set up my Django function to run in the background from button onclick?
I have a Django project and one of the functions currently runs onclick of my html - def follow(request): api = get_api(request) followers = tweepy.Cursor(api.followers_ids, wait_on_rate_limit=True).items() for x in followers: try: api.create_friendship(x) except Exception: pass return render(request, "followed.html") The function runs and follows the followers of the authorised user. My issue is that when deployed on my pythonanywhere web app the function will load in the browser and then timeout after around 10 minutes. I have tested on users up to 100 followers and it all works. This would be fine but the Twitter API has a rate limit and so for some users who have large followings this function will take a long time to complete. Is there a way of diverting to the followed.html and keeping the function running in the background until it is completed? I have added the oauth functions just in case they are needed too - def auth(request): # start the OAuth process, set up a handler with our details oauth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET) # direct the user to the authentication url # if user is logged-in and authorized then transparently goto the callback URL auth_url = oauth.get_authorization_url(True) response = HttpResponseRedirect(auth_url) # store the … -
Reverse for 'sales' with no arguments not found. 1 pattern(s) tried: ['sales/(?P<pk>\\d+)/$']
I have seen a lot of relatable questions and answers, I just haven't understood even after tweaking my code why it doesn't seem to respond. I am new to django, I am hoping someone can point me in the right direction.

Django Admin Customization (Change list display by the user)
At Django Admin, we can use "list_display" to choose which column to show. I want to customize Django admin so that we can decide which column to show dynamically (Not using "list_display) I want the user to be able to use something like a checkbox. Again, not by changing Python codes. I tried the following but it seems nothing to do with the display of listing. Dynamic fields in Django Admin It seems I need to override/extend some Django template using JavaScript but I am not so sure. Any comment would be greatly appreciated. (I much prefer to implement it in admin rather than outside of admin, though.) Many thanks, -
Django send mail from docker container how to expose port

HTML to PDF also with keeping the CSS & bootstrap styling in Django
I am trying to render an HTML page into PDF in Django by following this GitHub tutorial link. My views.py: def render_to_pdf(template_src, context_dict={}): template = get_template(template_src) html = template.render(context_dict) result = BytesIO() pdf = pisa.pisaDocument(BytesIO(html.encode("ISO-8859-1")), result) if not pdf.err: return HttpResponse(result.getvalue(), content_type='application/pdf') return None class ViewPDF(View): def get(self, request, *args, **kwargs): pdf = render_to_pdf('app/pdfpage.html', data) return HttpResponse(pdf, content_type='application/pdf') #Automaticly downloads to PDF file class DownloadPDF(View): def get(self, request, *args, **kwargs): pdf = render_to_pdf('app/pdfpage.html', data) response = HttpResponse(pdf, content_type='application/pdf') filename = "Invoice_%s.pdf" %("12341233") content = "attachment; filename='%s'" %(filename) response['Content-Disposition'] = content return response However I almost copy all the code from that tutorial link except pdfpage.html, I put there my custom made HTML page also with bootstrap and CSS styling. Now my problem is after converting and saving this pdf, it lost all the styling and bootstrap styling stuff, but those are also important for me. how can I solve this problem? -

Django feeding file data to a model
If you got a form that asks the user for a file upload and the file after some preprocessing gets a data dict which is fed to the model. How is the preprocessing step is to be done in this case? In the subclassed FormView's is_valid method one can do form.files to get the file obj, read it , preprocess it there and then feed the data to a model instance. But I think this would block the thread. What's the correct way? -
Modal Form Not Showing in Django
I have the the following modal that I am trying to use as a Create/Edit form for my SQLite3 data but nothing ever appears. I can connect this form to it's own URL and that works fine, but I am looking to include it within the same /communications url just as a pop-up (enabling the user to stay on the same screen and quickly fill out the form).

DRF ManyToManyFields with a Through Model
I have this M2M relation with through model as class Person(models.Model): name = models.CharField(max_length=128) def __str__(self): return self.name class Group(models.Model): name = models.CharField(max_length=128) members = models.ManyToManyField(Person, through='Membership') def __str__(self): return self.name class Membership(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) group = models.ForeignKey(Group, on_delete=models.CASCADE) date_joined = models.DateField() invite_reason = models.CharField(max_length=64) Please note that, I have extra fields date_joined and invite_reason in the through model. Now, I want to serialize the Group queryset using DRF and thus I choose the below serializer setup. class PersonSerializer(serializers.ModelSerializer): class Meta: model = Person fields = "__all__" class GroupSerializer(serializers.ModelSerializer): members = PersonSerializer(read_only=True, many=True) class Meta: model = Group fields = "__all__" and it is returning the following response, [ { "id": 1, "members": [ { "id": 1, "name": "Jerin" } ], "name": "Developer" }, { "id": 2, "members": [ { "id": 1, "name": "Jerin" } ], "name": "Team Lead" } ] Here, the members field returning the Person information, which is perfect.

Django-jsignature Fields Mixin
I have the below Model. class Job(models.Model): site_address=models.TextField() site_code=models.CharField(max_length=50) client=models.CharField(max_length=50) main_contractor=models.CharField(max_length=50) date_due=models.DateField() date_complete=models.DateField(null=True,blank=True) date_received=models.DateTimeField(auto_now_add=True) job_description=models.TextField() materials=models.TextField(blank=True) assigned_to=models.ForeignKey(User, on_delete = models.SET_NULL,null=True,blank=True) and also the below Django-signature model. class JSignatureModel(JSignatureFieldsMixin): name = models.CharField(max_length=50, blank=True, null=True) everything works ok and i can display, create a signature and save no problems. The issue is when i add the below. class JSignatureModel(JSignatureFieldsMixin): name = models.CharField(max_length=50, blank=True, null=True) sig = models.ForeignKey(Job, on_delete=models.CASCADE) when displayed it is asking me to manually select the job i want it to be related to instead of automatically been added when the job form is submitted. i have this working on another model which uses a foreign key link to the Job model. Is it because it's inheriting from JSignatureFieldsMixin and not models.Model? Im new to Django and Python and just trying to figure things out. Thanks -

Django - queryset based on list interval
I have a Django model and want to get a Queryset based on the order_by clause which is set to a time field in descending order. I do NOT want to return all these objects. I just want to return the objects in the interval start to end. For now I get all the objects in Queryset list and manually slice the python list (list[start:end). The problem is that the list contains over 100k records. So it is a time consuming option. Is there any way in which I can pass this start and end parameter to Django and it only returns the queryset list after applying that slice. -
Serializing many to many relationship with attributes does not show attribute in the relationship
My conceptual model is that there are DemanderFeature objects which have LoadCurve objects linked to them in a many-to-many relationship, along with a single attribute indicating "how many times" the two are associated, using an attribute in the many-to-many relationship called number. I have been struggling for quite a while now, reading many answers on stackoverflow but I just cannot get it to work in exactly the way that I want. This is my desired output, when looking at the detail view of a DemanderFeature: HTTP 200 OK Allow: GET, POST, HEAD, OPTIONS Content-Type: application/json Vary: Accept [ { "name": "testdemander", "loadcurves": [ {"name": "lc", "number": 5}, {"name": "lc2", "number": 10} ], // Other DemanderFeature fields removed for brevity... } ] The closest I have been able to get to this is with this setup: Models class LoadCurve(models.Model): created = models.DateTimeField(auto_now_add=True) finalized = models.BooleanField(default=False) owner = models.ForeignKey('auth.User', on_delete=models.CASCADE) name = models.CharField(max_length=100) length = models.IntegerField(default=0) deleted = models.BooleanField(default=False) demanderfeatures = models.ManyToManyField("DemanderFeature", through="DemanderFeatureToLoadCurveAssociation") class Meta: ordering = ['name'] constraints = [ models.UniqueConstraint(fields=["owner", "name"], condition=models.Q(deleted=False), name="loadcurve_unique_owner_name") ] class DemanderFeature(models.Model): created = models.DateTimeField(auto_now_add=True) name = models.CharField(max_length=100) owner = models.ForeignKey('auth.User', on_delete=models.CASCADE) demanderfeaturecollection = models.ForeignKey(DemanderFeatureCollection, on_delete=models.CASCADE) loadcurves = models.ManyToManyField("LoadCurve", through="DemanderFeatureToLoadCurveAssociation") deleted = models.BooleanField(default=False) geom = gis_models.PointField(default=None) … -
