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. But I want to save the whole form (with multiple form data) in DB. views.py def create_order(request): from django import forms form = OrderForm() if request.method == 'POST': forms = OrderForm(request.POST) if forms.is_valid(): po_id = forms.cleaned_data['po_id'] supplier = forms.cleaned_data['supplier'] product = forms.cleaned_data['product'] part = forms.cleaned_data['part'] order = Order.objects.create( po_id=po_id, supplier=supplier, product=product, part=part, ) return redirect('order-list') context = { 'form': form } return render(request, 'store/addOrder.html', context) forms.py class OrderForm(forms.ModelForm): class Meta: model = Order fields = ['supplier', 'product', 'part','po_id'] widgets = { 'supplier': forms.Select(attrs={'class': 'form-control', 'id': 'supplier'}), 'product': forms.Select(attrs={'class': 'form-control', 'id': 'product'}), 'part': forms.Select(attrs={'class': 'form-control', 'id': 'part'}), } HTML <form action="#" method="post" id="form-container" novalidate="novalidate"> {% csrf_token %} <div class="form"> <div class="form-group"> <label for="po_id" class="control-label mb-1">ID</label> {{ form.po_id }} </div> <div class="form-group"> <label for="supplier" class="control-label mb-1">Supplier</label> {{ form.supplier }} </div> <div class="form-group"> <label for="product" class="control-label mb-1">Product</label> {{ form.product }} </div> <div … -

I have installed WeasyPrint==0.42.3, but when I try to import it in Django, it raises the following error: ModuleNotFoundError: No module named 'weasyprint' When I look at the requirements.txt, it actually shows that it is installed.

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 … -

Test Django with dictionary in dictionary data
Description I'm using Django for my website and trying to write some unit tests. However, when using dict in dict data I met some errors. I found out that view received slightly different data. From {'class_id': '1', 'filter_options': {'full_name': 'user 1'}} in data of test file to <QueryDict: {'class_id': ['1'], 'filter_options': ['full_name']}>.

Reverse for 'bans' with keyword arguments '{'user': 1}' not found. 1 pattern(s) tried: ['bans/(?P<pk>[0-9]+)/$']
I am building a GroupApp and I am trying to add some group members in premium_members(ManyToManyField).

How to access a legacy database without creating a new table in it in Django
I was given access to a database to use on one of my Django projects. I set everything up and went to migrate the new models and I got an error. "Unable to create the django_migrations table ((1142, "CREATE command denied to user 'MyDatabaseName' for table 'django_migrations'"))" After looking into it, I see its because Django is trying to create a new table in that database. I don't have write access and I do not want it because I am pretty new at this and do not want to mess anything up. I am also not sure the owner would give it to me. Is there a way to get to use the legacy database without having to create a new table in it?
