TypeError: Object of type Reporter is not JSON serializable
I am trying to add the reporter with ajax but it is not working properly. When I send json data with {'reporter':reporter.name} then it creates the obj in the database successfully but I am not being able to display this newly created obj in the select option.

Django readonly_fields not showing data
My Orders model has 'rate' and 'total_amount' field. I had to derive rate from different model so i created 'unit_rate'. Same way i wanted my 'total_amount' fields should be multiplication of 'quantity' and 'unit_rate' which i tried by doing 'total_pay'. You can see my code for the same below. class OrderAdmin(admin.ModelAdmin): def unit_rate(self,obj): self.rate = Product.objects.get(pk=obj.order_id) return self.rate.price def total_pay(self,obj): self.rate = Product.objects.get(pk=obj.order_id) self.total_amount = self.rate.price * obj.quantity return self.total_amount list_display = ('order_id', 'order_item', 'order_status', 'delivery_address', 'customer', 'quantity','unit_rate','total_pay') readonly_fields = ('total_pay','unite_rate') admin.site.register(Orders,OrderAdmin) As 'total_pay' and 'unit_rate' are obtained from other columns, admin doesn't need to enter them. That's why i kept them on readonly_fields'. Problem is whenever is create order through admin interface, 'total_pay' and 'unit_rate' does not shows up in admin. It just shows dash like this -. Doing this since a while. I could really use your help.thanks -
Django view with simple GET method results in TypeError

Django DB design - Book specific unique URLs with unique_together
I have two models with one to many relationship. A Book has many Chapters. Both the models have a slug field. For Book the slug column is UNIQUE. For Chapter the book_id and slug are UNIQUE together. The Chapter model also has a field order. And book_id and order are UNIQUE together. This way, I can generate unique URLs for books automatically and allow duplicate slugs for different books. Current models.py: class Book(models.Model): # other fields slug = models.SlugField(max_length=80) def save(self, *args, **kwargs): if not self.pk: self.slug = unique_slug(self.title) return super(Book, self).save(*args, **kwargs) class Chapter(models.Model): #other fields book = models.ForeignKey(Book, on_delete=models.CASCADE, related_name='chapters') slug = models.SlugField(max_length=80) order = models.IntegerField(null=True) class Meta: constraints = [ models.UniqueConstraint(fields=['book_id', 'order'], name='unique_order'), models.UniqueConstraint(fields=['book_id', 'slug'], name='unique_slug')] ordering = ['order'] The downside here is, in my chapter views I have to query the book first and get the chapter slug with the matching book_id. While previously with just the chapter slug UNIQUE, I was just querying the chapter table alone. My goal is to have URLs like this book/rndmstrng-alice-in-the-wonderland/chapter/down-the-rabbit-hole book/rndmstrng-some-other-book/chapter/down-the-rabbit-hole Is there any issue in this design? Are too many UNIQUE constraints bad? Is there a better way to implement this? -
How to send data from custom.py to html - Django
Concept that I'm trying to achieve: A web application with speech enabled that displays what the user says, on UI. Example: If the user says "Hello there!", "Hello there!" should be displayed on the UI. What I have: Files that I have in my app: speech.py (has a variable(displayOnUI) that stores what the user says) speech.html (where I want to display what the user says) Note: speech.py repeatedly keeps listening to user and keeps storing what the user says in a variable(displayOnUI). What I tried: I tried passing the value of the variable displayOnUI which is in speech.py to view.py and then passing it to speech.html using context. speech.py displayOnUI= "Please say something.." def SpeechRecognition(): while 1: try: with sr.Microphone() as source: r.adjust_for_ambient_noise(source, duration=1) audioReceived = r.record(source, duration=3) displayOnUI= r.recognize_google(audioReceived) view.py from SpeechApp.speech import displayOnUI def speech(request): data = displayOnUI return render(request, "speech.html", {"data": data}) speech.html <div> <h3>This is what I heard: {{data}} <h3/> </div> Problem that I'm facing I'm able to display the initial value that is present in displayOnUI (that is "Please say something..") on UI, however I'm not able to display the updated value(user's command) of displayUI in speech.html.

Django form list field or json field?
I have a model called participants as below class participants(models.Model): username= models.CharField(max_length =50) votes = models.IntegerField(default=0) voted_by = ? Votes is the total number of votes given by users and single user can vote multiple times. If the user have voted then the user should wait 1 hour to vote again. Now i am wondering, how can i store users id in a way that it would be easier to know who voted how many times and the recent date and time the user have voted. Can someone suggest me or refer some examples that i can solve this problem. -
