Why is plotly failing to load in django project?
I am using Plotly.react() function to render a graph on my template HTML file. In the function, I am passing in the id for the HTML element where I want the graph to render, data for both x&y axis, plot type, and layout information. Excerpt from my code: var metricsOneGraphDiv = document.getElementById('metricsOne'); var metricsOneTraces = [{ x: {{rmabRisks.dates|safe}}, y: {{rmabRisks.counts}}, type: 'scatter', }] var metricsOneLayout = {{rmabRisksLayout | safe}} Plotly.react(metricsOneGraphDiv, metricsOneTraces, metricsOneLayout); I get the following error from the Firefox console when I try loading this view Loading failed for the <script> with source https://cdn.plot.ly/plotly-latest.min.js. I have tried to reinstall plotly, however, I get stuck waiting for the pip install to complete. Can someone please suggest a possible solution? Thanks in advance -
The page does not display information about created links in the admin panel. Django
The page should display a feedback form and links created in the admin panel. Created models: from django.db import models class ContactModel(models.Model): # feedback form name = models.CharField(max_length=50) email = models.EmailField() website = models.URLField() message = models.TextField(max_length=5000) create_at = models.DateTimeField(auto_now_add=True) def __str__(self): return f'{self.name} - {self.email}' class ContactLink(models.Model): # links icon = models.FileField(upload_to='icons/') name = models.CharField(max_length=200) def __str__(self): return self.name I connected the models to the admin panel: from django.contrib import admin from .models import ContactModel, ContactLink @admin.register(ContactModel) class ContactModelAdmin(admin.ModelAdmin): list_display = ['id', 'name', 'email', 'create_at'] list_display_links = ('name',) admin.site.register(ContactLink) Everything works correctly, you can create links in the admin panel. Below views.py: from django.shortcuts import render from django.views import View from .models import ContactLink class ContactView(View): def get(self, request): contacts = ContactLink.objects.all() form = ContactForm() return render(request, 'contact/contact.html', {'contact': contacts, 'form': form}) urls.py: from django.urls import path from . import views urlpatterns = [ path('contact/', views.ContactView.as_view(), name='contact'), path('feedback/', views.CreateContact.as_view(), name='feedback'), ] I go through the for loop through the code to return links from the admin panel: #links <div class="contact__widget"> <ul> {% for contact in contacts %} <li> <img src="{{ contact.icon.url }}"> <span>{{ contact.name }}</span> </li> {% endfor %} </ul> </div> #feedback form <form action="{% url 'feedback' %}" method="post"> … -
MultiValueDictKeyError at /homepage/detail when trying to query database with django
I understand from other posts that MultiValueDictKeyError is related to whatever is in the .html file isn't reaching the database.

Django template tags in HTML
I am trying to point an image source to a filepath tag I have specified in my views.py, but for some reason it won't load in the project index file, but will in the specific projects pages. And all my other tags on the same page work, so Am unsure what I am doing wrong? <img src="{{ filepath }}" class="card-img-top" alt="Project Image"> Appears in the page as <img src="" class="card-img-top" alt="Project Image"> which shows the alt text.

cannot retrieve values from database django
I have a table I am trying to retrieve values from. It has two foreign keys and that is it. I use get_or_create on the table and create an object. I verify with the admin panel that the object is there. Then, I try to retrieve it but I do not get the values even though I can see them in the admin panel. Here is the table: class req(models.Model): to = models.ForeignKey(User,on_delete=models.CASCADE) from = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return "request sent" In the piece of code below, what I retrieve I try to display it as it is in the p tag and also I tried doing req.to and req.from.first_name but in vain, I did not see any values. def get(self, request): u = get_user(request) try: my_requests = req.objects.get(from=u) except req.DoesNotExist: fr = None if fr == None: return redirect(reverse('dogpark:index')) if my_requests != False: context_dict['req'] = my_requests return render(request, 'myapp/req.html', context=context_dict) Can anybody see the problem that I cannot and comment ? -
pytest parametrize is deleting my fixturedata after first parametrize value
I have two fixtures: @pytest.fixture def all_users(): all_existing_group_names = Group.objects.all().values_list( "name", flat=True ) tmp_list = [] for group_name in all_existing_group_names: user = User.objects.create(username=f"user-{group_name}", password=group_name) group = Group.objects.get(name=group_name) user.groups.add(group) tmp_list.append(user) return tmp_list and @pytest.fixture def admin_user(all_users): User.objects.all() # is empty the second time return all_users And this is how my test looks like Class TestSomething: @pytest.mark.parametrize('first_val, second_val', [('test', 'test'), ('test2', 'test2'),..]) @pytest.mark.django_db(transaction=True) def test_something(self, all_users, first_val, second_val): ... In my test i am deleting some model instances through a post request(which in the view is wrapped with a transaction.atomic request). This is why i need transaction=True, because the deleted objects need to be there again when the second run of parametrize runs. Now, my problem is that if i use transaction=True, on the second run it will revisit my fixtures but now suddenly my database is empty, the Groups.objects.all() method doesn't return anything at all. If i switch back to transaction=False, it works but this way i have a problem because my post request deleted stuff that i need for the next parametrize run. What am i doing wrong? I don't get it :( ughhh -
Django Rest Framework - Write an explicit `.update()` method for serializer
I'm trying to make a put request using DRF but this error appears: AssertionError: The `.update()` method does not support writable dotted-source fields by default. Write an explicit `.update()` method for serializer `model.serializers.ModelSerializer`, or set `read_only=True` on dotted-source serializer fields. This is the view: class Model(GenericAPIView): def put(self, request, pk): model = MyModel.objects.filter(id=pk).first() serializer = ModelSerializer(model, data=request.data, partial=True) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) This is the serializer: class ModelSerializer(serializers.ModelSerializer): class Meta: model = MyModel fields = '__all__' def update(self, instance, validated_data): status = validated_data.pop('status', None) model = super().update(instance, validated_data) if status: model.set_status(status) model.save() return model What is wrong with the update() method? Also, how can I only update one field of the object? -
Django: is there something like an id of a queryset?
I am looking for something that I can use to have the value of a queryset. This would be the replacement of the use of filters like this: # Normal myquerysetA = Model.objects.filter(name="John",age=20) # Value i wanna query_id = myquerysetA.query_id() # Equivalent myquerysetB = Model.objects.filter(query_id=77777) myquerysetB == myquerysetA True -
Кнопка "Вернуться назад" со всеми заполненными параметрами формы Django
При ошибке на стороне сервера после отправки формы должна выходить страница с ошибкой и кнопкой вернуться назад. Если нажать на кнопку, то произойдёт редирект на страницу формы, и поля формы должны быть заполнены также, как до первой отправки. Не совсем понимаю, как это реализовать. Сохранение полей формы можно реализовать через request.session, но как их вывести? -

Angular Django app cache not being cleared?
we have a really weird problem going on. We are developing an app that uses Angular on the frontend and Django on the backend, and we did extensive testing, with our team and an external QA team pick the app apart. So we are sure this should work. This week our clients started their client testing, and the client is reporting that the app is not working as expected. Basically, it wouldn't load the dynamic edit-user/:id/ route, and the app would be 'stuck'. (Additionally, some API calls that would retrieve dates return null). We thought it might be a caching problem (because the app wasn't working with dynamic data before we've added the HashLocationStrategy to represent the URL) so we connected to the clients PC and tried to clear the cache. Didn't work. The client also reported the same issue on Safari, Chrome and Firefox (Client uses a Mac machine), and also their iPad. Could it be a network caching issue? Then I built a new version with the package versioning inside the app to make sure we have the same version but it still behaves like that. (gets stuck on dynamic routes) This is quite a complicated issue because … -

I'm trying to implement a filter to search, for example, cards created by a specific Agent, i'm able to do this but i would like to show in the dropdown only the Agents related to the Manager, the dropdown list now shows all Agents in the database models.py class StandardProfile(models.Model): name = models.CharField(max_length=200, null=True) surname = models.CharField(max_length=200, null=True) phone_number = models.CharField(max_length=200, null=True) class Meta: abstract = True class Manager(StandardProfile): user = models.OneToOneField(User, null=True, on_delete=models.CASCADE) class SubManager(StandardProfile): user = models.OneToOneField(User, null=True, on_delete=models.CASCADE) manager = models.ForeignKey(Capo, null=True, on_delete = models.SET_NULL) class Agent(StandardProfile): user = models.OneToOneField(User, null=True, on_delete=models.CASCADE) manager = models.ForeignKey(Manager, null=True, on_delete = models.SET_NULL) subManager = models.ForeignKey(SubManager, null=True, blank=True, on_delete = models.SET_NULL) class MembershipCard(models.Model): agent = models.ForeignKey(Agent, null=True,blank=True, on_delete = models.SET_NULL) client = models.ForeignKey(Client, null=True,blank=True, on_delete = models.SET_NULL) creation_date = models.DateTimeField(auto_now_add=True, null=True) activation_date = models.DateTimeField(null=True,blank=True) expiration_date = models.DateTimeField(null=True,blank=True) views.py @login_required(login_url='login') def profilePage(request, pk): #www.mysite.com/profilePage/<pk> user = User.objects.get(id=pk) … -
Best Python framework for event driven microservices
I want to build a simple system consisting of a few microservices to present patterns of this architecture in my thesis. Each service will have only one instance and I'll use docker-compose to run it locally. I'm going to show some auth mechanisms, CQRS and communication via events. Which Python framework would you consider best for this kind of thing, from your experience? I've read that asynchronous frameworks are well suited for microservices, so I'm particularly interested in FastAPI/Celery combo. Aside of that, I'm good at DRF. -
Why is my Selenium selector pulling a dict? (Django/Python 3.8)
I've just updated selenium in my django app on PythonAnywhere. This is my code: from selenium import webdriver def Synonym(): chrome_options = webdriver.ChromeOptions() chrome_options.add_argument("--headless") chrome_options.add_argument("--disable-gpu") browser = webdriver.Chrome(options=chrome_options) browser.get("https://www.synonym.com/synonyms/test") test = browser.find_element_by_class_name("logo").text browser.quit() return test But it gives me an error: AttributeError: 'dict' object has no attribute 'text' When I grab it without the .text this is what it gives me: {'ELEMENT': '0.3567871003333163-1'} I'm using a paid account and should be able to access any site. Sidenote: is there a way to stop selenium from making /tmp/ files and folders? Thanks!
