Unable to subscribe to GCP Pub/Sub when running a server of Django application

Djago time widget not showing up
All I want to do is add time widget to my form so I can easily pick the time. Everything is very simple, the page is loading but the widgets don't show up. No error nothing. I am thinking maybe I didn't set up the form widgets correctly but not sure what I did wrong. Here is my Forms.py- from django.contrib.admin import widgets from django.contrib.admin.widgets import AdminDateWidget, AdminTimeWidget, AdminSplitDateTime class WorkOutForm(ModelForm): class Meta: model = WorkOut fields = '__all__' widgets={ 'start':AdminTimeWidget(), 'end':AdminTimeWidget(), } Here is the Models.py. You will notice "start" and "end" fields are timefield- class WorkOut(models.Model): date=models.DateField(auto_now_add=True, auto_now=False, blank=True) day=models.DateField(auto_now_add=True, auto_now=False, blank=True) start=models.TimeField(null=True) name=models.CharField(max_length=100, choices=move) weight=models.CharField(max_length=100, blank=True) rep=models.CharField(max_length=100, blank=True) pedal= models.CharField(max_length=100, blank=True) stretchtype =models.CharField(max_length=100, blank=True) end=models.TimeField(null=True) note=models.TextField(max_length=300, blank=True) def __str__(self): return self.name And here are the views linked to it even though I don't think it has much relevance- def workout(request): form=WorkOutForm() if request.method=="POST": form=WorkOutForm(request.POST) if form.is_valid(): form.save() context={'form':form} return render(request, 'myapp/enter_workout.html', context) def update_workout(request, pk): order=WorkOut.objects.get(id=pk) form=WorkOutForm(instance=order) if request.method=='POST': form=WorkOutForm(request.POST, instance=order) if form.is_valid(): form.save() context={'form':form} return render(request, 'myapp/enter_workout.html', context) And the form on HTML page is also very basic,so don't think there is any issue there either- <form action="" method="POST"> {% csrf_token %} {{form}} <input type="submit" value="Submit"> … -

How to store variables in Django database field?
I've been trying to figure out if it's possible to store a variable in a Django database field. Here is an example: class Message(models.Model): message = models.TextField() And then in the HTML form field, someone inputs something like this: Hi {{ user.first_name }}, thanks for signing up to our {{ company.name }} newsletter. That then gets saved to the database, and when an email goes out, those fields are automatically populated with the appropriate data. Hope this makes sense. Thanks. -

React Component not Refreshing Django REST
everyone ! I'm learning React by myself, and I'm stuck here where I'm doing a REST API for a Chat APP, when I POST a new message, the component don't refresh by itself, I have to refresh the page.

how to convert my html string into its own datatype?
I'm fairly new to JS and HTML, Working on a Django project now makes me crazy about it . I have passed a variable from context from Django toward html. I noticed the datatype of the data is converted to string by defualt. views.py: context = {'segment': 'index', "service_data": data } html_template = loader.get_template('index.html') return HttpResponse(html_template.render(context, request)) HTML pages <div class="card-body"><canvas id="myAreaChart" width="100%" height="40"></canvas></div> <script type="text/javascript"> const service_data = "{{ service_data }}" </script> In Javasript, I can see the datatype of service_data is string. I'd like to traverse it as a array, but it is converted to string. const data = Array.from(service_data); //this is converted to objet not arrary.. function prepareChartData(data) { var chartData = []; for (var i = 0; i < 10; i++) { let timestampe = data[i][0] let dat_list = data[i][1] chartData.push([timestampe, dat_list]); My service_data is a fairly large data from django backend, hence, I do not want to use split or something to convert it. The service_data snipet: Please ignore those &gt, etc, not sure why HTML added them, but image the data itself is a very nested dictnary.
