How to insert images from render( , , context) in Django?
guys! New in Django so maybe it's a silly question. I have a .json file that keeps information about shop's clothes including "img". The goal is to otput all the information about products in a single "for loop". So I've written such lines {% for product in products %} <div class="col-lg-4 col-md-6 mb-4"> <div class="card h-100"> <a href="#"> <img class="card-img-top" src="{% static '{{ product.img }}' %}" !!! problem is here alt=""> </a> <div class="card-body"> <h4 class="card-title"> <a href="#"> {{ product.name }} </a> </h4> <h5>{{ product.price }}</h5> <p class="card-text"> {{ product.description }}</p> </div> <div class="card-footer text-center"> <button type="button" class="btn btn-outline-success">Отправить в корзину</button> </div> </div> </div> {% endfor %} Everything works fine except the line concerns an image. In devtools I get the next path "/static/%7B%7B%20product.img%20%7D%7D". But in the .json file it looks like "img": "vendor/img/products/Brown-sports-oversized-top-ASOS-DESIGN.png". I am totally confused about that situation and definitely in a bind. I appreciate any help -
Upload an image from html template file to a django python class without using model
I am a beginner in coding. I am building an application in Django which requires an image captured through the html and then it should be used in a python class where i want to pass the image to opencv. i am using the following code: store.html:- {% csrf_token %} Image: <input type="file" name="camCapture" accept="image/*" id="image" required> <input type="submit" name="submit" value="submit" required> filter.py: class Pic2Filter(django_filters.FilterSet): img = cv2.imread('CV/static/images/IMG_1159.jpg') img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB) hImg,wImg,_ = img.shape boxes = pytesseract.image_to_data(img) lst = [] for x,b in enumerate(boxes.splitlines()): if x!=0: b = b.split() if len(b)==12: x,y,w,h = int(b[6]),int(b[7]),int(b[8]),int(b[9]) detected_text = b[11] lst.append(detected_text) #Product identification products = Product.objects.values_list('name', flat=True) d = [x.lower() for x in lst] # make dict of list with less elements search_result = [] for m in products: if m.lower() in d: searched_name = Product.objects.filter(name__iexact=m) search_result += searched_name i want to use the captured image instead of CV/static/images/IMG_1159.jpg. Is there a way to do it without using a model or saving? -
The field 'email' clashes with the field 'email' from model 'account.account'. Django3.2
Newbie in django here. I've been trying to create a simple site with django and i just finished creating the models. However, when I try to makemigrations, i get this: SystemCheckError: System check identified some issues: ERRORS: account.Account.email: (models.E006) The field 'email' clashes with the field 'email' from model 'account.account'.

Django event stream deployment with daphne
I'm trying to redeploy my Django project on my local ubuntu server to document all the steps, I managed to get it up and running but the problem is my real time notifications are not working, I'm using Django event stream for the notifications. I have setup the Daphne and Nginx accordingly and the event stream connection is opened too but I'm not receiving the real time notifications. There is no code related issue as the same code is on production server and notifications are working there. The problem is I'm not getting any error message so I don't know where to look to debug the issue. I'm sharing the configurations which I did I think I'm missing something in the setup. I have followed Django channels official deployment here. My Nginx and Daphne configurations are in the below images. .

Why we use action attribute in html form? What is the difference between action and redirect?
Yes! you must be thinking it is a basic question or stupid etc, but i didn't get the answer of this question on the entire google.. I got the answer of this question is that the action always sends data to the url which was given to the action attribute and just redirect the on that url.. My questions are: Why we use action whenever we can use redirect in django or other backends?: if we send data to the url why we send? Where we use this data? -
Django SECRET_KEY protection VS ability to run project locally
I have read many topics here about django SECRET_KEY, but most of them are about how to store it in environment variable instead of settings.py, at this stage everything is clear. Currently i keep it in .env locally and in config var on heroku. Im confused about 2 conflicting points that i can't combine together. On the one hand, it considers as a good practice to keep SECRET_KEY in secret. From the docs: Instead of hardcoding the secret key in your settings module, consider loading it from an environment variable Besides that github warms in email if you have SECRET_KEY explicit in your code: GitGuardian has detected the following Django Secret Key exposed within your GitHub account. On the other hand, i want to allow anyone to run my project locally. I have it on github and deployed version on heroku, but it's still a demo project which is used as part of portfolio, not a serious one. What is the solution here? To break the protection convention and put it explicitly in settings.py? -
Turn django rest framework url completely off

As i have it on my own settings shown below REST_FRAMEWORK = { 'DEFAULT_RENDERER_CLASSES': [ 'rest_framework.renderers.JSONRenderer', ] } When I go to my localhost:8000/products I want to see simply a 404 page and not the JSON rendered products.

How to Create New User from User_Profile in DRF?

I want to download an image from server using httpresponse mediaobj = Media.objects.filter(id=fileid)[0] response = HttpResponse(content_type='application/force-download') response['Content-Disposition'] = 'attachment; filename=%s' % mediaobj.filename() response['X-Sendfile'] = mediaobj.mediafile.path Above code is from my view. But i am getting 0 byte file in return Why? Actually its a 142KB file. -
Can i upload files in one django filefield as a list of files?
I have created a webpage where a candidate can apply for jobs. There, they can list different previous experiences. I am handling all experience details by concatenating them in my models and splitting them while fetching. how should I handle files in such a case? My Applicant model has the FileField called company_doc. Can it also somehow take multiple files so that I can retrieve them via some indexing? is that possible?
