Add and Update Post from custom html forms in Django
I've created a custom HTML form for my model, just like I want to add a post from the front-end. I already created a page with the name add-post.html add-post.html <form method="POST" action=""> {% csrf_token %} <input name="title" type="text"> <textarea spellcheck="false" name="description"></textarea> <input type="file" name="image" @change="fileName" multiple /> <select required name="priority"> <option value="Low" selected>Low</option> <option value="Medium">Medium</option> <option value="High">High</option> </select> <input type="checkbox" name="on_hold"> <button type="submit">Add ToDo</button> </form> model.py class Todo(models.Model): title = models.CharField(max_length=100) image = models.ImageField(null=True, blank=True, upload_to='todo/images/') description = RichTextField() Low, Medium, High = 'Low', 'Medium', 'High' priorities = [ (Low, 'Low'), (Medium, 'Medium'), (High, 'High'), ] priority = models.CharField( max_length=50, choices=priorities, default=Low, ) on_hold = models.BooleanField(default=False) forms.py class TodoCreationForm(forms.ModelForm): class Meta: model = Todo fields = ('title','image','description','priorities','priority','on_hold') No, I want to use the above custom HTML form to post data and save it to this model database. instead of using {% form.as_p %} And I also created a particular page to update this post from the front-end but don't know how to make it work. Can you please guide me on how can I save data from the custom form and also update it from the custom form? Appreciate your response :) -

DRF PUT on Viewset/Serializer does not fire post_save signal on model instance
I have the following DRF viewset: class MyViewSet(RetrieveModelMixin, ListModelMixin, UpdateModelMixin, GenericViewSet, CreateModelMixin, DestroyModelMixin): serializer_class = MySerializer queryset = My.objects.all() lookup_field = "uuid" The following Serializer: class MySerializer(serializers.ModelSerializer): class Meta: model = My fields = [ 'uuid', 'name' ] I have a signal stored in signal.py in the app @receiver(post_save, sender=My) def my_updated(sender, instance, created, **kwargs): if not created: print('MySignal Fired') The signal is imported in apps.py. The signal is working when I open a terminal and run the .save() method on a instance. The app is also declared in the django config. Any ideas? BTW. when executing the .PUT on the API it saves everything nicely in the DB. So the api is doing it's work. Not sure why the signal is not firing though. -

Django Column Data Gets Encoded
I'm using raw query to get data from server and data that I receive from one specific column gets converted to bytes, like so: "date": "b'2021-02-09'" Column itself: CASE WHEN some.column IS NULL THEN DATE(some.other_column) ELSE DATE(some.column) END AS "date", I believe that DATE() is getting messed up by Python somehow, cause I have exact same CASE column below, but with TIME() and that column outputs data as str, not bytes My question is: How do I bypass that behavior and receive data from that column as str, or, if possible - how do I decode column data in serializer? -
Django - Saving data without using input fields/forms
I am a novice, apologies if this question seems silly. I need to save some data into MySQL database. There are no input fields. The user should click a button, and a table is updated. The data to be saved is two foreign keys and a PK. Here is my model class Bids(models.Model): id=models.AutoField(primary_key=True) userid = models.ForeignKey(Writer, on_delete=models.DO_NOTHING, related_name='userid ') orderid = models.ForeignKey(Orders, on_delete=models.DO_NOTHING, related_name='orderids') biddatetime=models.DateTimeField(auto_now_add=True) I have tried writing several functions to save these fields into table bids but no joy so far. Hers's a sample. def saveBid(request): if request.method!= "POST": return HttpResponse("Action Not Allowed") else: biddatetime=request.POST.get('biddatetime') bids= Bids(biddatetime=biddatetime) order=Orders(id=id) user= CustomUser() user.save() bids.save() Pls assist -
Django, Djoser social auth : State could not be found in server-side session data. status_code 400
i'm implementing an auth system with django and react. The two app run respectively on port 8000, 3000. I have implemented the authentication system using the Djoser package. This package use some dependencies social_core and social_django. Everything seems to be configured ok. I click on login google button...I'm redirected to the google login page and then back to my front-end react app at port 3000 with the state and code parameters on the url. At this point I'm posting those parameters to the backend.

Faced the following problem, I need to save filtered data to excel. The problem is precisely in getting the filtered data, saving in excel is not a problem. My class based view: class RequestList(FilterView): template_name = 'MQueryboard/Requests/RequestList.html' filterset_class = Filter_Adjustments_view model = Adjustments paginate_by = 3 def get_queryset(self): filterset_class = Adjustments.objects.order_by('-dateadjustment') return filterset_class def get_context_data(self, *args, **kwargs): _request_copy = self.request.GET.copy() parameters = _request_copy.pop('page', True) and _request_copy.urlencode() context = super().get_context_data(*args, **kwargs) context['parameters'] = parameters return context def post(self, request): if request.method == 'POST': response = adjustments_to_excel(Adjustments.objects.all()) return response else: return render(request, 'MQueryboard/Requests/RequestList.html', {}) The adjustments_to_excel function - in order not to load the view, data is sent to the script to generate an Excel file. Here I do not understand how I can get the filtered queryset in the post function. Now, as a "stub" is the selection for all fields of the model. Please tell me how you can do this. I've been struggling with this question for a week, nothing has been working out yet. Thanks in … -
