Implicitly wiring an HTML document to a Django Rest Framework API View
I'm following along with this tutorial. I have the back-end ready to go, but the author has wired up a base.html to the DRF view and it seems to be dynamically resolving. There isn't a hardcoded reference to an HTML file in the entire project, but he's loading multiple files as if by magic. This is not explained in the tutorial, and I can't seem to invoke this behaviour in Django. How do I point a DRF API view to an html document without actually defining a path to the file? -
Are there any tutorials or videos on Django-dash
I want to build a python powered dashboard. After doing some research i felt that Django-dash would suit my need pretty well. However i have not been able to get it running. I have gone throught the instructions on the Git hub page. I also tried to follow the instructions and install the example but that did not work either. There are so many errors that it gets frustrating. I am using a windows machine and for starters would like to get it installed on windows. I am relatively new to django but am aware of the basics. -
Unable to save the Userprofile after post_save

Cannot run Django heroku app locally on Windows
So, I want to test my all locally, but something goes wrong. After installing virtualenv, activating it, installing requirements.txt and running collectstatic I try to run app with heroku local web -f Procfile.windows I get [OKAY] Loaded ENV .env File as KEY=VALUE Format And that's all. I wait for about 30 mins and then stop execution. Then I get 16:07:33 web.1 | Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x042BEF60> 16:07:33 web.1 | Traceback (most recent call last): Traceback is empty. This is all output. Sometimes, when I wait for about only 1-2 minutes no messages appear at all. File Procfile.windows looks like: web: python manage.py runserver 0.0.0.0:5000 What's wrong? Why this exception occurs? -

django makemigration won't recognize GenericRelation field
I'm trying to add a GenericRelation field to my model and then run : from django.contrib.contenttypes.fields import GenericRelation class FAQ(models.Model): # the rest of my model fields answer = GenericRelation(SomeModel) after adding the last line to the code I run: python manage.py makemigrations < appname > but I get the "no changes detected" message.I get results when I add other fields like models.CharField() to the Model. Also I tried GenericModel with other models and it still didn't work. is there any reason I can't make this migration?? is makemigrations supposed to recognize this change at all or does django not create a column in the table for this field at all?? thanks in advance. -
Django Query : keep only the earliest records with references to a particular instance
I have a Match object which has ReferenceFields to a Player1 and Player2 (Player objects) and a DateTimeField. I want to create an optimized query that returns only the most recent upcoming match for each team. Imagine, for instance, the list of upcoming games are as follows: Tomorrow Player A vs Player B 2 weeks Player A vs Player C 3 weeks Player B vs Player C The expected result of the 'next match' query would only return Player A vs Player B, because the other matches contain a player who is in an earlier upcoming match. At present I am doing this through a non-Django filter (just a basic filtering function). But the problem is that it's quite expensive on DB hits. Would prefer to do it through a QuerySet if possible. -
Python Django returning 400 GET messages on script and images
I have a python server running. And at the onset, it runs the application perfectly loading the images and scripts. If I leave it running for 24hrs, I discover that it gives a GET 400 error messages of not loading the images/scripts. I also observed that if I replace all the applications altogether with the backup, then it likely starts running perfectly again.

201 created status code sent by django rest framework interpreted as failiure by jquery $.ajax call
I am simply using django-rest-frameworks CreateAPIView which returns a response containing a 201 status code. I would expect this to work with the standard javascript/jquery ajax functions. But apparently it does not. Here is a similar issue where Retrofit throws an error. Any Ideas on how to debug this on jquery? -

Defining a Django query set with a many-to-one relationship with calculation
I have three models: Assets, AssetTypes and Services. Assets need to get serviced every n months, and have a many-to-one relation with services. class AssetType(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(verbose_name="Asset Type", max_length=100) service_period = models.PositiveSmallIntegerField(verbose_name="Service Period (in months)", null=True, blank=True, default=12) class Asset(models.Model): id = models.AutoField(primary_key=True) type = models.ForeignKey(AssetType, on_delete=models.PROTECT) def service_period(self): return AssetType.objects.get(pk=self.type.id).service_period def service_history(self): return self.service_set.all().order_by('-date') def service_due_date(self): if self.service_period()==None: return None elif self.service_history().count()==0: return datetime.strptime('2017-01-01', '%Y-%m-%d').date() else: last_service_date = self.service_history().latest('date').date return last_service_date + timedelta(self.service_period()*30) def service_overdue(self): return ((self.service_due_date()!=None) and self.service_due_date() < date.today()) class Service(models.Model): id = models.AutoField(primary_key=True) date = models.DateField() asset = models.ForeignKey(Asset, on_delete=models.CASCADE) I'm trying to work out how to make a query set that would return a list of assets that are overdue for their service. I feel like using a model method is a red herring, and that I would be better off defining a query set filter? I need the list of overdue assets to be a query set so I can use further query set filters on it. Any assistance would be greatly appreciated! -
Get email in another model after user is created in django

Reverse_lazy and URL Loading?
I'm trying to wrap my head around Django concepts, but I struggle with the URLResolver reverse_lazy(). As far as I know, I have to use reverse_lazy() when I want to reverse to an URL that has not been loaded. So when I create a CBV and state a success_url, I use reversy_lazy. This means that the url is not imported when the file executes. This is confusing to me because I think the server loads all the URLs while starting before executing anything. So how come the URL is not loaded in time of execution? I would be very happy if someone would give me an answer to this. -
Sent JSON data to DJANGO. Now I can't get it back
Good day. I sent JSON data to my server (js to Django) and in the server, I just saved the data (still in JSON format) directly to the database without converting it to string. Now I want to retrieve that same data but it's not working. Here is my code: $.ajax({ url: '/submitdata/', type: 'POST', dataType: 'text', data: JSON.stringify(userdata), contentType: 'application/json; charset=utf-8', success: function (){ alert('success'); }, error: function (){ alert('sorry, an error occurred'); )}; And in the server def submitdata(request): if request.is_ajax(): If request.method == 'POST': save_data = my_model( username='michael', userdata = request.body) save_data.save() It worked fine. It got saved into the database. The problem I have now is retrieving it. I tried this: In my client $.ajax({ url: '/getdata/', type: 'POST', data: { user_name: 'michael' }, success: function (result){ JSON.parse(result); }, error: function (){} )}; And in my server if request.method == 'POST': user_name = request.POST['user_name'] datum = my_model.objects.get(username=user_name) return HttpResponse(datum) It doesn't work. It gives me an error: Unexpected character at line 1 column 1 of JSON data Note: I tried to use JSON.parse on the returning data -

The word "action" in an iframe causes xxs warning
I have built a bulk-emailer for the Django admin, It's been in production for two years. I use Sendgrid to send the emails. The admin part is divided into a two step form. In step one, you enter subject, recipients etc and then the content in a Tinymce WYSIWYG. Step two fetches the template from Sendgrid and displays the email in the Sendgrid template via an iframe as a preview... Fine, everything works great and as I said has done for two years... Except for today when I tried sending an email containing the sentence: "Extending the interrogation of the brief to the interrogation of the client—assessing if there’s enough action being taken by the client to contain the situation and enable an effective reputation management exercise." This causes Chrome/Opera (not tested elsewhere yet) to complain about XSS: This page isn’t working Chrome detected unusual code on this page and blocked it to protect your personal information (for example, passwords, phone numbers and credit cards).
