Django REST Framework: Use of 'pk' in get_object_or_404
I'm a beginner with the Django REST framework and am building an app that summarizes articles with headers. I'm trying to get information from the Article model to pass into the Summary one. I'm having trouble understanding the use of get_object_or_404 in this scenario (how to instantiate a model) and how I use the pk argument. I tried changing the status URL to status/<int:article_id> and passed article as the pk, but I get a 404 when running the POST request. I'm stuck on how to use that argument otherwise. How do I instantiate a model from my request by using get_object_or_404 properly? views.py: import json from django.shortcuts import render, get_object_or_404 from django.http import HttpResponse, JsonResponse from rest_framework.decorators import api_view from .models import * @api_view(['POST']) def get_summary(request, pk): article = get_object_or_404(Article, pk=pk) mdl = Summary() return JsonResponse(mdl.preprocess(article.content), safe=False) models.py: # Article class class Article(models.Model): headings = models.CharField(max_length=200) content = models.CharField(max_length=500000) # Summary results class (so far) class Summary(models.Model): preprocessor = TextPreprocessor() in_text = models.CharField(max_length=500000) topics = models.CharField(max_length=200) def preprocess(self, text): return self.preprocessor.preprocess(text) urls.py: from django.urls import path, include from rest_framework import routers from .api import * from .views import * router = routers.DefaultRouter() router.register('my_api', SummaryViewSet, 'api') urlpatterns = [ path('api/', include(router.urls)), … -
AttributeError at /akolaprofile/ 'MyRegistration' object has no attribute 'get'
I am trying to create a user profile by using Django's UserChangeForm. I'm not using Django's User model and had created a custom user model (MyRegistration) by inheriting AbstractBaseUser. I have also assigned my custom user model to AUTH_USER_MODEL in the settings.py.

best practice for Django junction table model structure
I am using a junction table called "UserRole" for 2 different Django model called CustomUser and Role to specify many to many relationship from both of the table.

how to analyzing financial stock data properly
I would like to do a lot of analysis/performance/statistics on my stock portfolio, which I plan to track with my app. E.g.: Week performance Month performance Year performance Best performer and a lot of other things I can't imagine right now... Where I'm struggling right now: - What is a good/the best way to archive this? - Also to show this info on a dashboard --> I think I should store this information somehow... But how to do this on a daily/weekly/whatever basis? --> I don't see a way to do such things while runtime? --> Maybe there is also an MVP solution, that can evolve into a top-notch solution?

Django pass input data from an HTML file to a python script and then send the final data to another HTML file
I'm trying to build a simple dictionary in Django. In the home.html file there's a form, which asks the user to enter a word. This word should 'become a variable' in a python script which needs it to retrieve certain data from an API. import json import urllib.request url = 'https://api.dictionaryapi.dev/api/v2/entries/en_US/' + user_input response = urllib.request.urlopen(url) result = json.loads(response.read()) final_word = str(result[0]['word']) + ' \n\n' final_def = str(result[0]['meanings'][0]['definitions'][0]['definition'])) 'user_input' would be the variable where the input is stored It should then pass the data obtained from the API (in this case final_word and final_def to another HTML file, final.html I can't figure out how to do this. Any help is appreciated. Comment if I need to add some of the code. Forgive my bad english. -
Styling a email link in Django sent email
I used the example from this example email authorization : to do a user authorization email, which works fine. My email link displays as something like: Hi rascal345, Please click on the link below to confirm your registration: http://127.0.0.1:8000/activate/Mjk/aoi2oo-b778abe73e5c8c0a31910d82039d5d67/ I would like to try to style this link so that it shows as a single clickable button or anchor type link (rather than the link as shown above). I have had a look at various suggestions, but I'm sure how to display this link as a single styled button say. Any suggestions? regards Russell -
Dynamically save the form
I am trying not to use formset in my form. Instead of that, I trying to create form dynamically and save all forms data in DB. Currently, I can create a dynamic form, but the thing is I fail to save all data from the form even though I create multiple forms. Now my code only can save only one form.

How to send data from any customized HTML form to Django model form without using jinja {{form}} template
This is not a bug-based problem. Basically, an advice-seeking one. I am a newbie and a great fan of Django's function-based view. It allows me to customize as I need. Like I can customize the HTML form as I want. If I wish, I can also put any icons or images or any things inside my <form> </form> tag. On the other hand, the class-based view also provides lots of attractive features in CRUD operation with the jinja form template and Django's model form. So to take advantage of those features I want to use Django's model form. But as I need to customize my <form> </form> also, I need to create an HTML form also, instead of the jinja model form (bootstrap widgets based modification is not enough for it.). So how can I send data to Django's model form from my customized HTML <form>. Kindly suggest me an overall idea in which way I should approach to solve it? You can also provide me any blog or article or tutorial types of stuff. Thanks for reading the full post. -
Best way to modify the fields in response in django rest?
I have a serializer that gives this data class PostSerializer(serializers.ModelSerializer): class Meta: model = Post fields = ('id', 'name', 'cost', 'currency') class UserSerializer(serializers.ModelSerializer): posts = PostSerializer(many=True) class Meta: model = User fields = ('id', 'name') and it gives the response like this, { "id": 1, "name": "joe", "posts": [ { "id": 20, "name": "first post", "cost": 20.00, "currency": "USD" }, { "id": 21, "name": "second post", "cost": 30.00, "currency": "USD" } ] } However I want to change/add the fields of the response based on few conditions, Eg. if cost is less than 25, make it zero and add a discount field for every post. This is how I am doing. class MyPostView(APIView): def get(request): query_set = User.objects.all() user_and_posts = UserSerializer(query_set) response_data = user_and_posts.data # I am modifying the serializer data here :< for post in response_data['posts']: post['discount'] = 10 # some value if post['cost'] < 25: post['cost'] = 0 return Response(serializer.data, status=status.HTTP_200_OK) To me modifying the primitive data like this is not looking right, is there any alternate way in django rest to do this? or could've done better with serializer? In general, what's the best way to alter the response data we get from serializer and format it … -
Django Page not Loading Favicon in Chrome
I have a Django website with multiple pages, all of them load the favicon without errors on the top browsers (Chrome, Mozilla, Opera...) but recently I have noticed that in Google Chrome, the favicon in my index page isn't load, instead, I get a console error: GET http://127.0.0.1:8000/favicon.ico 404 (Not Found) (this is also happening in production) The problem with this is that I'm not making any request to /favicon.ico, instead, my code to load the icon is: <link rel="icon" href="{% static 'logo.ico' %}"> This is the same code used in the other pages and it loads fine in them, I have already tried to delete cache, delete Favicon folder in Chrome and to load the icon with full path: http://127.0.0.1:8000/static/logo.ico (if I paste this in browser I can see the icon) I don't understand why Chrome keeps making a default request to /favicon.ico instead of to the actual favicon. My Google Chrome version is: Version 91.0.4472.101 (Official Build) (64-bit) Django version is: 3.1.2 I don't think it is an issue with static files, because the favicon is loaded in other browsers, but also it is not a cache problem, do you have any suggestions about how to solve it? -

Workaround for logging out a user logged in using HTTP Apache LDAP in django
In the Django 2.2 application, user is allowed to log in "through http (Apache LDAP)" by providing username and password in the browser prompt (as shown below): Problem is that when I logout the user using the default django logout defined in django.contrib.auth, the user is still able to access the application. In simple words, the django login and logout have no effect on the application. I have learnt that, the only way to logout the user is by closing the browser window. But I wanted to implement the logout functionality usin django. After a bit of googling about this issue, I found something relatable here, which shows the following method: class HttpAuthMiddleware(object): def process_request(self, request): if request.path == '/accounts/logout/': httpResponse = HttpResponse() httpResponse.status_code = 401 httpResponse.headers['WWW-Authenticate'] = 'Basic realm="<same realm as in the http server>"' return httpResponse else: # check for http headers - maybe the user is already logged in using http auth ... This is a workaround for the logout feature. It basically checks for the request.path == '/accounts/logout/' which helps me in using the default django logout function. I want this snippet to redirect the user back to the same login prompt that browser provides (as … -
