How do I properly condense this Python IF statement?
I am pretty new to Python, and trying to find a better way to code this. There has to be a way but just not sure how to do it. The two queries are essentially the same, so there has to be a way to reduce. Is there a more efficient way to do this? if set_date is not None: params = {CarTow.ACCEPTED,CarTow.UNCONFIRMED} if is_rejected != 'true': query = query\ .filter(createddate__lte=set_date) \ .car_statuses(CarTow.ACCEPTED) \ .order_by('-createddate') else: query = query\ .filter(airdate__lte=set_date) \ .car_statuses(CarTow.ACCEPTED,CarTow.UNCONFIRMED) \ .order_by('-createddate') return query Sorry if this is a simple question, newbie here. -
Django. JSON response not working as expected
In Django, I am simply sending some JSON back when a user makes a POST request to my server. I am sending different JSON responses depending on the information the user inputs to my api endpoint. (I am using POSTMAN to test this) My API checks if the passwords a user supplies match, and if so sends a success message, however if not send a failure message. If they match or don't match, the same JSON is always sent back. Which is not wanted. Here is my code: def signup(request): if request.method == 'POST': if request.POST.get('password1') == request.POST.get('confirmPassword'): return JsonResponse({'message': 'Well Done'}) print('Success') else: print('Do not match') return JsonResponse({'error': 'Password fields do not match'}, status=400) Postman input: { "password1": "test123", "confirmPassword": "deedeedde" } RESPONSE: { "message": "Well Done" } -
Render ValidationError in template
I am making a page for adding products to the web shop by the user, and I am having troubles with displaying ValidationError in my template. The ValidationError is raised if selected category isn't the most specific category to select. To select a category, the user has to go trough chained dependent combobox selection, where you start with one combobox for main category and once you select main category, another <select> appears for selecting a subcategory, and so on until the innermost subcategory is selected. category is a field on my base Product model (from which other models, such as Book or Shoes, inherit) and isn't listed in ModelForms' inner Meta class fields, thus I can't have clean_category method on my ModelForms. Here is my view: @login_required def product_create_view(request): if request.method == 'POST': main_category = request.session.get('main_category') create_product_form = mappings[main_category](request.POST) if create_product_form.is_valid(): obj = create_product_form.save(commit=False) category = request.session.get('category') if Category.objects.get(id=category).is_leaf_node(): obj.category = Category.objects.get(id=category) obj.save() else: raise forms.ValidationError('Please select most specific category.') return render(request, 'products/product_create.html', { 'categories': Category.objects.filter(parent=None) }) How to render the ValidationError in the template, i.e. how can I have my ValidationError in my {{ field.errors }}? Currently I am seeing a stack trace. -

I am pretty beginner in django and in coding too. Stuck for a while with an error.

Change structure of JSON data for API POST request with Django
I have a Django REST API endpoint with this structure, that I need to post to an external API: { "body": [ "...", "...", "...", ], "title": [ "...", "...", "...", ], "id": [ "...", "...", "...", ] } The first item under 'body' goes with the first under 'title' and 'id', and so forth. The problem I'm having is that the API in question expects JSON data with the following structure: { "texts": [ { "body": "...", "title": "...", "id": "..." }, { "body": "...", "title": "...", "id": "..." }, { "body": "...", "title": "...", "id": "..." }, ], "language": "EN", } And I can't figure out how have my endpoint mirror that structure, with the bodies, titles, and ids grouped together, those groupings nested under texts, and with the language parameter appended at the end. The serializer I'm using in my views.py looks as follows: class MyReasonsSerializer(serializers.Serializer): body = serializers.SerializerMethodField() title = serializers.SerializerMethodField() id = serializers.SerializerMethodField() def get_body(self, obj): return obj.reasons.order_by('transaction_date').values_list('body', flat=True) def get_title(self, obj): return obj.reasons.order_by('transaction_date').values_list('title', flat=True) def get_id(self, obj): return obj.reasons.order_by('transaction_date').values_list('transaction_date', flat=True) class ReasonsData(RetrieveAPIView): queryset = Market.objects.all().prefetch_related('reasons') authentication_classes = [] permission_classes = [] serializer_class = MyReasonsSerializer Thanks in advance for any advice! -

Attaching profile to user model in django
I am trying to add some extra information to my user model...via the one-to-one link example here: https://simpleisbetterthancomplex.com/tutorial/2016/07/22/how-to-extend-django-user-model.html#onetoone So I took their example: from django.db import models from django.contrib.auth.models import User class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) bio = models.TextField(max_length=500, blank=True) location = models.CharField(max_length=30, blank=True) birth_date = models.DateField(null=True, blank=True) Implemented it on my own in an /accounts app that seemed to of showed up in my application once I got authentication and authorization stuff working in my djanog app. So the models.py in my /accounts looks like: class APOUser(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) institution = models.ForeignKey("mainpage.InstitutionMember", on_delete=models.PROTECT) on_site_status = models.ForeignKey("mainpage.SiteStatus", on_delete=models.PROTECT) refer_to_as = models.TextField(max_length = 30, blank=True) #if the above is custom room_preference = models.ForeignKey("housing.Room", on_delete=models.PROTECT) I can say: python3 manage.py makemigrations accounts It works, but when I try to run a python3 manage.py migrate it chokes with an error about a lazy reference in one of my other app's models: ValueError: The field housing.HousingRequest.user was declared with a lazy reference to 'accounts.apouser', but app 'accounts' isn't installed.

HTML select form with option to enter value does not store the entered value as object field in django
I have a Django form in which I have several drop-down menus that have an option to enter a custom value. In order to enter a custom value, I am using the following implementation to toggle a textbox whenever the custom value is selected from this implementation http://jsfiddle.net/6nq7w/4/ Whenever I select an option from the dropdown list and save the form, the model's object value (In this case it is EmployeeInformation.dept) retains the value selected, but it is not the case if I enter a custom value. In the below example, I use a chained dropdown implementation to load the Department based on the Department ID. For example - Let's say while filling the form I select the value Sales then the value of EmployeeInformation.dept = Sales, whereas when I select the option as Enter Manually and enter a new value say DeptXYZ the Django model object does not take this manually entered value as the data for the field Dept. models.py class EmployeeInformation(models.Model): name = models.Charfield(max_length=30,null=False, blank=False) dept_id = models.ForeignKey(DepartmentInformation, on_delete=models.SET_NULL, null=True) dept = models.ForeignKey(SubDeptInformation, on_delete=models.SET_NULL, null=True) salary = models.DecimalField(null=True, blank=True, decimal_places=2, max_digits=10) form.html <!DOCTYPE html> <html> <script> function toggleField(hideObj,showObj){ hideObj.disabled=true; hideObj.style.display='none'; showObj.disabled=false; showObj.style.display='inline'; showObj.focus(); } </script> <body> <form … -

How to configure Django media root in Apache

Redirect to download Django
I want to track how many times file has been downloaded. I see it this way: 1) Instead of <a href="{{ file.url }}" download>...</a>, I should redirect user for download view; <a href="download/{{ file.id }}/{{ file.name }}">...</a> file.id and file.name needed for proper work of function bellow. 2) In my download view I need to registrate download of specific file, let's say I have registrate_dl function that does its job. Also, I need to take that {{ file.url }} value like in first link from first paragraph. 3) Finally, I registered download for specific file and got {{ file.url }} as file_url variable. But, if, at the end of view function I place return redirect(file_url), it just redirects me to file, without starting download. So, how should i return this file_url, and trigger download? -
Computing the SHA256 hash of a FileResponse objects content
I have a file for which I have computed its SHA256Sum and have verified it is correct. hash1 = computeSHA256(filepath) I need to compute the hash again, but this time using the values inside response.streaming_content where response is a Django FileResponse object, which I have done as follows: response = FileResponse(request, open(filepath, 'rb'), content_type='application/json') content = b''.join(response.streaming_content) h = hashlib.sha256() h.update(str(content).encode('utf-8')) hash2 = h.hexdigest() This issue here is that hash1 != hash2. For example: hash1 = 7836496a8e17dac5aad5dea15409b06558d0feaf6c39198eae620afebb1fa097 hash2 = 70a3e07b20e722652740e93702b70322d042b9710b3087228e70551ad8301086 Can anyone see where I have gone wrong to cause the two hash values to not be equal?

Request object has no user during process_request in django middleware
I have a custom middleware that I'm writing which I have added to my list of middlewares in settings. The middleware needs to access some attributes on the user attached to the request, and this works fine for requests made directly to the backend server. However, for CORS requests that come from the frontend, I'm seeing that the user is an AnonymousUser during process_request, and they only show up as authenticated in process_response. I have 'django.contrib.sessions.middleware.SessionMiddleware' and 'django.contrib.auth.middleware.AuthenticationMiddleware' above my custom middleware in settings.py, so I would have expected this to work. Any advice on different things I should try to be able to access the authenticated user in my custom middleware's process_request method with CORS requests?
