video not working in safari with django static files
It's a video page to make a website with django. It comes out well on Chrome, but it doesn't come out on Safari... The same goes for mobile safari. Playsinline and video tag are all correct. Video source is the address of a video on the Internet, but it doesn't play when I import it from a static file. Is there a solution? If I have to encode, I also want to know the code that automatically encodes when I load a video. -
Django - Can't access data from object in many to many relationship
In my Django project, I am trying to create a website that streams TV shows. Each show belongs in many categories, hence the use of many to many relations in my model.

module 'django.template' has no attribute 'resolve_variable'
I am porting an old Django project to Django 3.2. I have come across this code segment, which causes an exception to be raised.

How to pass image file from one page to another in multi-page form
In my django web app, I need to pass a form from one page to another so it can be completed and saved. In this form is an ImageField, and when I try the following, all other fields come pre-populated, but the image field shows "no file selected". Written below is a simplified version of my code. If I uncomment the code where I create an instance of the form in the views.py, the image field in the HTML shows the message "Upload a valid image. The file you uploaded was either not an image or a corrupted image." I have no idea why every other field can get passed into the next page, except the image field. Does anyone know how to do this? Or is there another way to go about this? models.py class MyModel(models.Model): name = models.CharField(max_length=50) age = models.CharField(max_length=50) picture = models.ImageField(default=None, upload_to='media/') forms.py class MyForm(ModelForm): class Meta: model = MyModel fields = '__all__' views.py def index_view(request): if request.method == 'POST': form = MyForm(request.POST, request.FILES) if form.is_valid(): ''' instance = form.save(commit=False) form = ConnectorForm(data=request.POST, files=request.FILES, instance=instance) ''' return render(request, 'main/page2.html', { 'form': form }) else: form = MyForm() return render(request, 'main/index.html', { 'form':form, "base":base }) def … -
Getting AttributeError: sender while iterating to get specific values
Getting "AttributeError: sender" is thrown as the exchange query iterates. Same with other values (message_id, etc) too. My only option at this point is to put a try/catch around it and need to refactor a lot of content under the loop.

How to retrieve all messages in a Twilio Programmable Chat Channel?

django searches for url which does not exist in my current project. Why is this happening? The project used to exist but no longer
i used to have an app in a project called catalog but i have deleted the project upon completion. Currently i have started a new project, but i have realised that the django searches for catalog which was an app in the old project. Instead of django searching for urls in my new project. i uninstalled anaconda and reinstalled it with django to see whether that will solve the issue but it still remains. One thing i noted was that in the previous project which contained catalog as a app i imported the Redirect View and redirected the homepage which was empty to the url of the app so that it rather acts as the index. Now whenever i run the server it points to the page where the redirect was done in my current project which does not exist throwing the exception below. Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/catalog/ Using the URLconf defined in main.urls, Django tried these URL patterns, in this order: admin/ ^media/(?P<path>.*)$ The current path, catalog/, didn’t match any of these.

Django / React - Production API URL routing issues
I have a backend Django REST API that also helps serve my React frontend. I currently have an issue with my API requests url paths to my Django API in production for every page except my home page... API URL's that work: I'm able to visit my home page, within my home page, I have a GET request to my API which works great and loads data as expected. This is the only working GET request of my website because the API URL path is correct to my urlpatterns syntax. API URL's that DON'T work: The issues arise when I visit a page OTHER than the home page of my React app. My API requests to Django on other pages are using the wrong URL path according to my network panel (they are also responding with index.html), which has me believe I set up my django URLs wrong.

It gives me a MultiValueKeyDictError every time I submit the form. I know I can use forms.py to do the same thing but I want to explore the HTML way of doing this. My HTML file <form action = "" method = "post"> {% csrf_token %} <label for = "LogType"></label> <input id ="LogType" type = "text" value = "{{ user.department }}"> <label for ="DelayCategory">Delay Category</label> <select id = "delaycategory" class = "form-control"> {%if user.department == 'TechAssembly'%} {%for techdelay in techdelay%} <option value = "{{ techdelay.DelayCode }}">{{ techdelay.DelayCategory}}</option> {%endfor%} {%endif%} {%if user.department == 'Testing'%} {%for testdelay in testdelay%} <option value = "{{ testdelay.DelayCode }}">{{ testdelay.DelayCategory}}</option> {%endfor%} {%endif%} </select> <label for = "iterations">Iterations</label> <input type = "number" id = "iterations"> <center><input type="submit" value=Submit id = "button"></center> </form> My Views.py file def rulesView(request, user_name): testdelay = TestingDelayCategory.objects.all() techdelay = TechDelayCategory.objects.all() if request.method == "POST": rulesnew = rules() rulesnew.DelayCategory = request.GET['DelayCategory'] rulesnew.LogType = request.POST('LogType') rulesnew.iterations = request.POST('iterations') rulesnew.save() context = { 'techdelay':techdelay, 'testdelay':testdelay, } return render(request, 'rules/rules.html', context) -
No "Access Control-Allow-Origin' header is present even when Django CORS_ORIGIN_ALLOW_ALL = True
I just deployed my React/Django web app to a VM. Everything worked fine on my local before deployment. Just to test, I attempted to use my site with the development server. When my React code (statically bundled in the Django app) makes the following api call to http://localhost:8000/token-auth/ (this endpoint is automatically constructed from django rest_framework.views.obtain_jwt_token): fetch('http://localhost:8000/token-auth/', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify(data) }) the following error message is received: Access to fetch at 'http://localhost:8000/token-auth/' from origin 'http://34.XXX.XXX:8000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled. Note that the curl from an external origin (my local machine pinging the vm) works fine: curl -X POST -H "Content-Type: application/json" -d '{"username": "wgu_test_user", "password": "fgDq7YUmcd3n"}' http://34.XXX.XXX:8000/token-auth/ so this error seems solely to do with CORS. Strangely, after I whitelisted the domains, and even used CORS_ORIGIN_ALLOW_ALL = True in my settings.py, I still get the same problem. I did restart the development server after changing this file and saving. As one possible solution, …
