Django looking for template that doesn't exist
I made some major changes to my site and now when I click a specific link, it tries to go to a page that doesn't exist (rightfully so) but I can't find any reference to that non-existent page in my code so I can't direct it properly. views.py from django.shortcuts import render from .models import BakingPost from django.views import generic def index(request): num_posts = BakingPost.objects.all().count() context = { 'num_posts': num_posts, } return render(request, 'food_blog/index.html', context=context) class BakingListView(generic.ListView): model = BakingPost # paginate_by = 10 class BakingDetailView(generic.DetailView): model = BakingPost urls.py from django.urls import path from . import views urlpatterns = [ path('', views.index, name='index'), path('bakes/', views.BakingListView.as_view(), name='bakes'), path('bake/<int:pk>/', views.BakingDetailView.as_view(), name='bake_detail'), # path('post/new/', views.post_new, name='post_new'), # path('post/<int:pk>/edit/', views.post_edit, name='post_edit'), ] navbar.html <nav> <div id="div_navbar"> <ul class="ul_navbar"> <li class="li_navbar"> <a class="a_navbar" href="{% url 'index' %}">Home</a> </li> <li class="li_navbar"> <a class="a_navbar" href="{% url 'bakes' %}">Baking List</a> </li> </ul> </div> </nav> bake_list.html {% extends 'food_blog/base.html' %} {% block content %} <h1>Baking List</h1> {% if bake_list %} <ul> {% for bake in bake_list %} <li> <a href="{{ bake.get_absolute_url }}">{{ bake.title }}</a> ({{bake.author}}) </li> {% endfor %} </ul> {% else %} <p>Nothing in the oven</p> {% endif %} {% endblock %} When I click on "Baking … -
A URL of a Hyperlinked Model Serializer returns '{"detail": "not found."} for a model with custom PK
class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) website = models.URLField(max_length=30, null=True, blank=True) class ProfileViewSet(viewsets.ModelViewSet): lookup_field = 'user' serializer_class = ProfileSerializer queryset = Retailer.objects.all() class ProfileSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Profile fields = ['website', 'user', 'url'] extra_kwargs = { 'url': {'view_name': 'profile-detail', 'lookup_field': 'user'}, 'user': {'lookup_field': 'username', 'view_name': 'user-detail'} } The code above lists all profiles and their URL's in JSON format. However, when a URL is clicked, it returns '{"detail": "not found."} instead of showing the details of the profile. Any idea? Thanks! Django version: 3.0.4 Django Rest Framework version: 3.11.0 -
python timer decorator with outputting classname
I am creating a little helper tool. It is a timer decorator (not so special) for measuring the execution times of any method. It prints the calculated execution time on the console with useful informations. def timer(func): """@timer decorator""" from functools import wraps from time import time def concat_args(*args, **kwargs): for arg in args: yield str(arg) for key, value in kwargs.items(): yield str(key) + '=' + str(value) @wraps(func) # sets return meta to func meta def wrapper(*args, **kwargs): start = time() ret = func(*args, **kwargs) dur = format((time() - start) * 1000, ".2f") print('{}{}({}) -> {}ms.'.format( func.__module__ + '.' if func.__module__ else '', func.__name__, ', '.join(concat_args(*args, **kwargs)), dur )) return ret return wrapper This gives me the modelname, and the functionname like that: user.models.get_matches(demo) -> 24.09ms. I want to have the class name in the output, too: user.models.User.get_matches(demo) -> 24.09ms. How can I get the class name of the function ('func') from inside the wrapper? Edit: Great thanks to Hao Li. Here is the finished version: def timer(func): """@timer decorator""" from functools import wraps from time import time def concat_args(*args, **kwargs): for arg in args: yield str(arg) for key, value in kwargs.items(): yield str(key) + '=' + str(value) @wraps(func) # … -
How to transform a list of dictionaries in Django view to return it as JSON?
I am calling the Giphy API using another wrapper API which returns a list of dictionaries. I am having hard times to transform the data to return it to AJAX. The data is returned as InlineResponse200 with three properties. According to the docu the dict consists of strings mainly. def get_gifs(request): # create an instance of the API class api_instance = giphy_client.DefaultApi() # API Key api_key = 'NGSKWrBqtIq1rFU1Ka11D879Y1u4Igia' # Search term q = request.POST.get('query') # Query parameters limit = 2 offset = 0 rating = 'g' lang = 'en' fmt = 'json' try: # Search Endpoint api_response = api_instance.gifs_search_get(api_key, q, limit=limit, offset=offset, rating=rating, lang=lang, fmt=fmt) pprint(api_response) except ApiException as e: print("Exception when calling DefaultApi->gifs_search_get: %s\n" % e) response = api_response.data JsonResponse(response) return render(request, response) # Returns: TypeError: Object of type Gif is not JSON serializable [...] response = api_response.data return render(request, response) # Returns: TypeError: join() argument must be str or bytes, not 'Gif' [...] response = api_response.data serialized_obj = serializers.serialize('json', response) return render(request, serialized_obj) # Returns: AttributeError: 'Gif' object has no attribute '_meta' [...] response = api_response.data[0] serialized_obj = serializers.serialize('json', response) return render(request, serialized_obj) # TypeError: 'Gif' object is not iterable Going nuts.. -

Bookmark Implementation methods in Django
I am trying to add a bookmarking system to my website however, I am kinda stuck on how to implement this: My approach following the link: https://evileg.com/en/post/244/ is class BookmarkBase(models.Model): class Meta: abstract = True user = models.ForeignKey(Profile,on_delete=models.CASCADE, verbose_name="User") def __str__(self): return self.user.username class BookmarkPost(BookmarkBase): class Meta: db_table = "bookmark_post" date = models.DateTimeField(auto_now_add=True) obj = models.ForeignKey(Post,on_delete=models.CASCADE, verbose_name="Post") class BookmarkBlog(BookmarkBase): class Meta: db_table = "bookmark_blog" date = models.DateTimeField(auto_now_add=True) obj = models.ForeignKey(Blog,on_delete=models.CASCADE, verbose_name="Blog") However, I was also wondering if the approach of creating a many to many relationships inside my user model with each object is also correct or not: so I will have : class Profile(AbstractUser): ''' Custome fields ''' bookmark_blog = models.ManyToManyField(Blog, blank=True, related_name='b_blogs') bookmark_post = models.ManyToManyField(Post, blank=True, related_name='b_posts') -

I am calling an async AJAX function to trigger a view which itself requests API data. Everything works fine and the API data is returned properly.

Django saving data to wrong fields
When I create an object in Django it saves the data to the wrong fields. When I make the following postman request: The return serialized data is correct. But the data saved to the db is not which looks like: The first two fields are correct but the rest are not. It saves the price as the rating, the weight_unit as the price, the user id as the weight and the rating as the user_is. View class CoffeeViewSet(viewsets.ViewSet): def create(self, request): serializer = CoffeeSerializer(data=request.data) if serializer.is_valid(): c = Coffee.objects.create( company = serializer.validated_data.get('company'), rating = serializer.validated_data.get('rating'), weight = serializer.validated_data.get('weight'), weight_unit = serializer.validated_data.get('weight_unit'), blend = serializer.validated_data.get('blend'), price = serializer.validated_data.get('price'), user = request.user ) print(c) return Response(serializer.data, status=status.HTTP_200_OK) return Response(serializer.data, status=status.HTTP_401_BAD_REQUEST) Serializer class CoffeeSerializer(serializers.ModelSerializer): class Meta: model = Coffee fields = ['company', 'blend', 'rating', 'price', 'weight_unit', 'weight'] also when I print validated_data is correct so my assumption is something with how the object is saved is not correct but I can not figure out. validated data OrderedDict([('company', 'Stumptown'), ('blend', 'Hair Bender'), ('rating', 7), ('price', Decimal('16.00')), ('weight_unit', 'OZ'), ('weight', Decimal('12.00'))]) What is going on here? -
How to call an API endpoint async via Django view
I want to make an async API request to get gifs from the Giphy API. The user triggers the AJAX call and therefor the related view by clicking the submit button. I then want to populate the DOM with the returned GIFs. Right now when I click the submit button, the page reloads and nothing happens. I don't even see the print within the view function. Where do I mess up? Does it even make sense to set up a view for this or just call the API within the AJAX directly? html <script type="text/javascript"> window.CSRF_TOKEN = "{{ csrf_token }}"; </script> <form> <label for="search">Search</label> <input placeholder="Search gif" id="search" type="search" name="q" action="{% url 'get_gifs' %}"/> <button type="submit" id="btnSearch">Go</button> </form> urls.py from blog.views import get_gifs urlpatterns = [ # Gyphy Search path('get_gifs', get_gifs, name='get_gifs'), ] Ajax (function($) { $('#btnSearch').on('click', function() { var query = $('#search').text(); e.preventDefault(); $.ajax({ type: 'get', async: true, url: '/get_gifs/', data: { 'query': query, 'csrfmiddlewaretoken': window.CSRF_TOKEN // from blog.html }, success: function(data) { console.log(data); }, error: function(xhr, status, error) { // shit happens friends! } }); }); }(jQuery)); Views.py def get_gifs(request, query): print('fired') # create an instance of the API class api_instance = giphy_client.DefaultApi() # API Key api_key = … -

Django session variable gets deleted when back button is clicked
I am new to django. I want a page (lets say page X) to be accessible by the user only once (that too by a redirect). So what I did is used session variables to do this: This is the view for the page from where I want to redirect the user to X - def MainPageView(request): //Some code which doesn't use or modify session variables request.session['seen_status'] = False redirect ("url_of_X_%d" % some_int) This is the view of X - def Status(request,id): if request.session['seen_status'] == False: //some code which shows the page content request.session['seen_status] = True return render(page) //page contains a button 'A' to go to the next page else: //page to display if user has already seen the page. This works fine if I go to X and refresh (that is, the else block gets executed). But, if the user goes to the next page by clicking the button 'A' and comes back using the back button of the browser, he can see the page again! I tried to debug this by using print statements, that is by printing request.session['seen_status'] but I get an error: Not Found: /favicon.ico Further, on clicking the back button, I don't get anything like: … -
