Why am i getting server 500 error in Django?
I have been trying to use the Django template inheritance feature for my project Since I've added {% block content %}s I am now getting a server error 500 whenever I try to run the child template. The base template runs fine. I am quite sure it has something to do with the content blocks, but I'm not sure why as I don't repeat any names of blocks and everything on the child template is contained within a block. Code goes like this: Base.html <!DOCTYPE html> <style> 'My style' </style> <html lang='en'> <head> <meta charset='UTF-8' {% block title %} webpage {% endblock %} <script>'Jquery reference'</script> </head> {% block script %} 'empty' {% endblock %} <body> <div id='navbar'> 'My navbar' </div> <div id='main_content_block'> {% block content %} <h1>This is my base</h1> {% endblock %} </div> </body> </html> Home.html {% extends 'main/base.html' %} {% block title %} <title>Home</title> {% endblock %} {% block script %} 'My javascript' {% endblock %} {% block content %} 'My content' {% endblock %} Thanks for your time -

Heroku Serving Localhost URL (127.0.0.1:8000) in Ajax API URLs in Django App
I'm currently working on a Django project and it's hosted on Heroku from GitHub. The front-end is served via Ajax calls to an API. let myurl = "/api/properties/"; $.ajax({ async: true, url:myurl, method:'GET', success: function(result){ .... } }); Everything works well on localhost, but on Heroku, I keep getting the error: GET http://127.0.0.1:8000/api/properties/ net::ERR_CONNECTION_REFUSED My API URL has no http://127.0.0.1:8000 on GitHub but on Heroku it has it after analyzing the source code on the Sources tab on Chrome: let myurl = "http://127.0.0.1:8000/api/properties/"; $.ajax({ async: true, url:myurl, method:'GET', success: function(result){ .... } }); I don't understand why my app's API URL isn't taking the domain URL https://appname.herokuapp.com/api/properties/ and it's across all the Ajax API URLs on the Django app. I have cleared my browser cache, opened the app in 'incognito mode' and even redeployed the project several times but not change. Kindly help me debug this and understand where the localhost URL is coming from. -

Integrate python-social-auth to drf-spectacular (Swagger)
I have a Django (DRF) project with OAuth2 based on python-social-auth and Swagger based on drf-spectacular. I need to integrate these two libraries together so that Swagger allow OAuth2 authorization, for example Google OAuth2. I found OAuth2 configuration for drf-spectacular in settings: SPECTACULAR_SETTINGS = { ... 'SWAGGER_UI_OAUTH2_CONFIG': { ... # Oauth2 related settings. used for example by django-oauth2-toolkit. # https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.3.md#oauth-flows-object 'OAUTH2_FLOWS': [], 'OAUTH2_AUTHORIZATION_URL': None, 'OAUTH2_TOKEN_URL': None, 'OAUTH2_REFRESH_URL': None, 'OAUTH2_SCOPES': None, }, ... } But I'm not really sure whether it fits me or not. I wrote this in my version of this config, but it appearently has no effect: 'SWAGGER_UI_OAUTH2_CONFIG': { 'OAUTH2_AUTHORIZATION_URL': 'https://accounts.google.com/o/oauth2/auth', 'OAUTH2_TOKEN_URL': 'https://accounts.google.com/o/oauth2/token', 'OAUTH2_SCOPES': ['openid', 'email', 'profile'], } Swagger still has no OAuth2. Any idea how to manage it? -

Ajax POST to an url then redirect to it
I'm building a web app where user can create markers on a leaflet map. Marker's details are saved in a backend with Django. My goal is to redirect the user to a detail page to fill marker's detail after clicking on the map. Here the js code to redirect to url create with an Ajax post. window.location.href = {% url 'create' %}; $.ajax({ url: {% url 'create' %}, data: { markers: markers_dict}, type: "POST" }).done(function (response) { console.log(response); }); but I'm struggling in the views.py because this redirect and AJAX post create two request one GET and another POST: def create_marker(request): if request.method == "POST": r = request.POST.get("markers") print(r) return JsonResponse({"response":"succeed"}) else: return JsonResponse({"response":"failed"}) It always returns the failed response even if it prints r in the console.

It returns Null. Instead of Null, I want to show users some similar matches with 2 and 1 symptoms.

Django class based views: page "GET" content disappears after "POST" request is executed

Django: Complex query sets take longer to execute
If I do an OR search filter on the fields of the model and the m2m model associated with it, the annotate, the query will take a long time to execute.(1500-2000ms) If I remove Q(tags__name__icontains=value) from the filter in the following queryset It works in about 30-50ms, so I think the cause is a problem with m2m. Filtering the m2m field from the model that is tied to m2m will loop through the entire through table, which in my opinion is time consuming. How can I rewrite the queryset to improve this? Video: 300k rows, Tag: 5k rows, video_tag_through: 1.3m rows # models.py class Tag(models.Model): name = models.CharField(unique=True, max_length=30) created_at = models.DateTimeField(default=timezone.now) ... class Video(models.Model): title = models.CharField(max_length=300) tags = models.ManyToManyField(Tag, blank=True) updated_at = models.DateTimeField(auto_now=True) ... class History(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) video = models.ForeignKey(Video, on_delete=models.CASCADE) ... class Favorite(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE video = models.ForeignKey(Video, on_delete=models.CASCADE) ... class Playlist(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) is_wl = models.BooleanField(default=False, editable=False) ... class Track(models.Model): playlist = models.ForeignKey(Playlist, on_delete=models.CASCADE, null=True) video = models.ForeignKey(Video, on_delete=models.CASCADE) ...

How to display data on Piechart from MYSQL database using django?
I am trying to extract data from the database and view the results on a pie chart, the charts should change dynamically when the values in the database change. But I am getting error in my script. Here is my view.py: def pie_chart(request): labels = [] data = [] queryset = Persons.objects.order_by('-id')[:3] for city in queryset: labels.append(city.firstname) data.append(city.salary) return render(request, 'breedingherdsummary.html', { 'labels': labels, 'data': data, }) Model.py: class Persons(models.Model): id = models.IntegerField(primary_key=True) firstname = models.CharField(max_length=100) lastname = models.CharField(max_length=100) address = models.CharField(max_length=100) dob = models.CharField(max_length=100) salary = models.IntegerField doj = models.DateField class Meta: db_table = "test" Here is my script: <script> var config = { type: 'doughnut', data: { datasets: [{ data: {{ data|safe }} , backgroundColor: [ '#FFA07A', '#E9967A', '#FA8072', '#F08080', '#CD5C5C' ], label: 'Salary' }], labels: {{ labels|safe }} }, options: { responsive: true, innerRadius: "40%" } }; window.onload = function() { var ctx = document.getElementById('pie-chart').getContext('2d'); window.myPie = new Chart(ctx, config); }; </script> Any help will be highly appreciated. Thank You!
