Is there a safe way to safely delete a Model field in Django?
I'm making a blog application in Django, and I want to modify a field of the Post class: I want to change the meta_description field to just description. From: class Post(models.Model): title = models.CharField(max_length=200) author = models.ForeignKey(User, on_delete=models.CASCADE) date = models.DateField(auto_now_add=True) meta_description = models.TextField(blank=True, null=True) body = models.TextField() def __str__(self): """ Show the title and the author in the admin Page """ return self.title + " by " + str(self.author) def get_absolute_url(self): return reverse("blog:article_page", kwargs={"pk": self.pk}) ⏎ To: class Post(models.Model): title = models.CharField(max_length=200) author = models.ForeignKey(User, on_delete=models.CASCADE) date = models.DateField(auto_now_add=True) description = models.TextField(blank=True, null=True) body = models.TextField() def __str__(self): """ Show the title and the author in the admin Page """ return self.title + " by " + str(self.author) def get_absolute_url(self): return reverse("blog:article_page", kwargs={"pk": self.pk}) When I do that in the model: I have an error Making the migration: Traceback (most recent call last): File "manage.py", line 22, in <module> main() File "manage.py", line 18, in main execute_from_command_line(sys.argv) File "/home/daniel/MEGA/my-git/github/Developer-road-website/venv/lib/python3.8/site-packages/django/core/management/__init__.py", line 401, in execute_from_command_line utility.execute() File "/home/daniel/MEGA/my-git/github/Developer-road-website/venv/lib/python3.8/site-packages/django/core/management/__init__.py", line 395, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/home/daniel/MEGA/my-git/github/Developer-road-website/venv/lib/python3.8/site-packages/django/core/management/base.py", line 330, in run_from_argv self.execute(*args, **cmd_options) File "/home/daniel/MEGA/my-git/github/Developer-road-website/venv/lib/python3.8/site-packages/django/core/management/base.py", line 368, in execute self.check() File "/home/daniel/MEGA/my-git/github/Developer-road-website/venv/lib/python3.8/site-packages/django/core/management/base.py", line 392, in check all_issues = checks.run_checks( File "/home/daniel/MEGA/my-git/github/Developer-road-website/venv/lib/python3.8/site-packages/django/core/checks/registry.py", line 70, … -
devtools: Open response HTML in new tab
I an ajax/fetch request fails, my framework (django) does display a nice debug page, which contains a lot of useful information. In chrome devtools I can see a preview of this debug page. Is there a way to open the output of the POST request in a new tab? If I use right-button-click "open in new tab" then chrome does a GET. But the GET does not trigger the exception which I would like to debug. -
Django API didn't detect a field in my database
I'm doing the Django official tutorial, here are the models I wrote and migrated from django.db import models class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField(name="date published") class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) votes = models.IntegerField(default=0) and I used the command python manage.py shell to use the Django API and ran the following commands: >>> from polls.models import Question, Choice >>> from django.utils import timezone >>> q = Question(question_text="What's new?", pub_date=timezone.now()) and got this error: Traceback (most recent call last): File "<console>", line 1, in <module> File "/home/mohammedi/.virtualenvs/mywebsite1/lib/python3.7/site-packages/django/db/models/base.py", line 501, in __init__ raise TypeError("%s() got an unexpected keyword argument '%s'" % (cls.__name__, kwarg)) TypeError: Question() got an unexpected keyword argument 'pub_date' what the hell is wrong with this -
Django: Unique ID's across tables
I was curious if there was a good solution to implement unique ID's between tables. class Voice(models.Model): id = .. <------| slug = ... | name = .... |-- No duplicate IDs | class Group(models.Model): | id = .. <------| slug = ... name = .... My hope is that when I get an ID in a view, selecting from one model will give me None but the other will always return the object (and vice versa). If there is a better approach feel free to share. Right now I am using the slug+id as query filters but would like to move away from that. -
(Django) Value set in session disappears after i render the request through the same view a second time
Here's what's happening: HTML Template "A" has a form that passes a variable with name="var1" to URL1. URL1 sends the request to VIEW1. VIEW1 then checks for and thereafter "gets" the "var1" variable successfully, and sets it in a session variable (request.session['variable'] = "var1" VIEW1 then renders the request to HTML Template "B", which has another form that passes a variable with name="var2" to URL1 again. URL1 sends the request to VIEW1 again. This time, "VAR1" is no longer available to "GET", but "VAR2" is. However, when i print the session variable (print(request.session['variable])), it no longer exists. My question is: Does passing a request back into the same VIEW a second time clear out any session variables you have set on the first pass? It certainly appears to be the case, but i can't figure out why. Before, I was using a global dictionary variable to store everything in, and it worked well, but it would expire if i didn't navigate quickly enough. Accordingly, i switched to storing my dictionary in the session. Thanks! -
Braintree Django Exception "can only concatenate str (not "tuple") to str"
I'm using Braintree Drop-in with my Django Project. It's working completely fine when I use it in development environment (manage.py runserver).

Translation key-based internationalization with Django
Django's default i18n system uses the code language (for instance, English) as translation keys; translations into other languages must be written from that base language. For instance, in a Django template, you would write {% trans "Hello" %} and then translate "Hello" into "Bonjour" or "Hola" in the French or Spanish translation file. This has a major flaw: words that are spelled the same in English cannot be translated differently in other languages. For instance, if I use {% trans "Fire" %} in two places of my code, one of which meaning the thing that burns, and the other using a cannon, I would need "Feu" and "Tirer" respectively in French; but Django's i18n forces me to choose a single translation for "Fire". The translation keys pattern solves this: I use translation keys such as {% trans "campsite.fire" %} and {% trans "cannon.fire" %} in my code, that I translate as "Fire" in an English translation file and as "Feu" and "Tirer" respectively in the French file. Is this a supported use of Django's i18n system? How do I inject variables into such translations? -
Django: Return back from POST-redirect in Chrome without dublicate pages
I have a detail-page, with a button that submits a GET or a POST request (tried both). This request performs an action and redirects to the same detail-page (thus refreshing it). Everything seems to be fine in Firefox, but in Chrome when I press Back Button, I get back on the same page again (so redirecting to the same page creates dublicates of this page in browser history). Can I somehow change this behaviour and remove those dublicates in Chrome also? -

Django Try/Except CBVs dealing with query returning None?
I am trying to include some exception handling to handle queries that return None, If none is returned I just want to display a simple JsonResponse message. Working with FBVs, I've done this pretty simply. But when using class based views, my except block is not doing as I expect. class BusinessDetailView(DetailView): model = BusinessDetail def get_object(self, queryset=None): business = self.model.objects.filter(**custom filters here)).values().first() logger.debug(Business: {business}') return business def get(self, request, *args, **kwargs): try: try: business = self.get_object() except BusinessDetail.DoesNotExist: return JsonResponse({'Error': 'Business Does Not Exist.'}) return JsonResponse(company, status=200) except Exception as e: logger.error(f'Error getting business detail with error: {e}') return JsonResponse({'Error': 'Database error, return to previous page'}, status=500) In the get_object method, the logger is returning Business: None as I expect. But in the get method, the BusinessDetail.DoesNotexist is not getting hit. The last Try/Except block is the one getting hit, returning return JsonResponse({'Error': 'DB error, return to previous page'}, status=500). From my understanding, the DoesNotExist exception would catch the query returning None? But in my case this is not occurring. Any help is greatly appreciated! -

Security issue with custom build decorator in Django
I am working with a custom build decorator in Django. my decorators.py: from django.contrib.auth import REDIRECT_FIELD_NAME from django.contrib.auth.decorators import user_passes_test def industry_required(function=None, redirect_field_name=REDIRECT_FIELD_NAME, login_url='app2:request_login'): actual_decorator = user_passes_test( lambda u: u.is_active and u.is_Industry, login_url=login_url, redirect_field_name=redirect_field_name ) if function: return actual_decorator(function) return actual_decorator Here is_Industry is a bool value, comes from models.py. my views.py: @method_decorator(industry_required, name='dispatch') class industryDetails(DetailView): model = Industry template_name = 'app/industryDetails.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['inserted_text'] = "inserted text from EmployeeDetails of views.py" return context in urls.py: path('industryDetails/<int:pk>/', views.industryDetails.as_view(), name='industryDetails') models.py also included if you need: class myCustomeUser(AbstractUser): id = models.AutoField(primary_key=True) username = models.CharField(max_length=20, unique="True", blank=False) password = models.CharField(max_length=20, blank=False) is_Employee = models.BooleanField(default=False) is_Inspector = models.BooleanField(default=False) is_Industry = models.BooleanField(default=False) is_Admin = models.BooleanField(default=False) class Industry(models.Model): user = models.OneToOneField(myCustomeUser, on_delete=models.CASCADE, primary_key=True, related_name='industry_releted_user') name = models.CharField(max_length=200, blank=True) owner = models.CharField(max_length=200, blank=True) license = models.IntegerField(null=True, unique=True) industry_extrafield = models.TextField(blank=True) Now my problem is, suppose a user with having primary_key=3, can easily visite another user's data having primary_key=2, by using http://127.0.0.1:8000/industryDetails/2/ (by changing the primary key in this address path). I need to stop this for my project. How can I code this in such a way that, any user can only visit his own details? -
Best approach for developing a stateful computation-heavy application with a rest-api interface using python?
I want to develop an end-to-end machine learning application where data will be in gpu-memory and computations will run on the gpu. A stateless RESTfull service with a database is not desirable since the traffic between gpu-memory and database will destroy the "purpose" of it being fast. The way I see it is that I need a way to "serve" the class (lets call it as experiment class) which has the data and the methods, then call them using rest apis. Right now I am using FastApi and initialize the experiment class in it which I believe is not optimal. My class (as well as the data) lives in FastAPI runtime. Kinda like, import experiment_class import FastApi app = FastAPI() my_experiment = expertiment_class() @app.get("/load_csv") my_experiment.load_csv("some_file_path") // do some more on the data ... There are two problems I am having a hard time with, One of them is the terminology: Is this really a stateful application ? Is there a word to describe what I am doing ? Is this a "Model, View , Controller" design, can it be a simple "Server-Client" or is it something completely different ? Do I need a "Web-server" , a "Web-framework" or a "Web-service" … -

Django Rest Framework to return desired results from two models
I have two models (customer, movie) and I would like to return (movie_name, customer_name, id) when I hit the URL (api/customer/1) and when I hit the URL (api/customer/1/movies) just wanted the movie names alone.

Running "tasks" periodically with Django without seperate server
I realize similar questions have been asked however they have all been about a sepficic problem whereas I don't even now how I would go about doing what I need to. That is: From my Django webapp I need to scrape a website periodically while my webapp runs on a server. The first options that I found were "django-background-tasks" (which doesn't seem to work the way I want it to) and 'celery-beat' which recommends getting another server if i understood correctly. I figured just running a seperate thread would work but I can't seem to make that work without it interrupting the server and vice-versa and it's not the "correct" way of doing it. Is there a way to run a task periodically without the need for a seperate server and a request to be made to an app in Django? -

I've printed out form and it's okey, then I've printed out forms.is_valid which gave me true, forms.save() also returns customer object so I don't know where to look now (this form updates user shipping data) form class customerUpdate(ModelForm): class Meta: model = ShippingAddress fields = ['city', 'country','zip_code','adress','phone',] exclude = ['customer','order','date_added'] widgets ={ 'city' :forms.TextInput(attrs={'class':'updateForm',}), 'country' :forms.TextInput(attrs={'class':'updateForm',}), 'zip_code' :forms.TextInput(attrs={'class':'updateForm',}), 'adress' :forms.TextInput(attrs={'class':'updateForm',}), 'phone' :forms.TextInput(attrs={'class':'updateForm',}), } Model class ShippingAddress(models.Model): customer = models.ForeignKey(Customer, on_delete=models.SET_NULL, blank=True, null=True) order = models.ForeignKey(Order, on_delete=models.SET_NULL, blank=True, null=True) city = models.TextField(max_length=50, null=True, blank=True) country = models.TextField(max_length=50, null=True, blank=True) zip_code = models.TextField(max_length=15, null=True, blank=True) phone = models.TextField(max_length=9, null=True, blank=True) adress = models.TextField(max_length=100, null=True, blank=True) date_added = models.DateTimeField(auto_now_add=True) def __str__(self): return str(self.adress) views def userView(request): userData = request.user.customer forms = customerUpdate(instance=userData) if request.method == "POST": forms = customerUpdate(request.POST, instance=userData) if forms.is_valid(): forms.save() context={ 'userData':userData, 'forms':forms } return render(request,'user.html', context) html {% load i18n %} <div class="editUserInfoWrapper"> <form method="POST" action="{% url 'user' %}"class="formUserPanel" > {% csrf_token %} <div class="container"> <div class="row"> <div class="col-sm-12 col-md-6"> <div class="form-group"> {{ forms.city }} </div> </div> <div class="col-sm-12 col-md-6"> <div class="form-group"> {{ forms.country }} </div> </div> … -
Django model override save() method raises error when calling super()
I have the following Django model: class TCDUser(AbstractUser): is_change_password = models.BooleanField(_("Cambiar Password?"), default=True) groups = models.ManyToManyField(Group, default=[], related_name='users', verbose_name=_("Grupos")) class Meta: verbose_name = _("Usuario") verbose_name_plural = _("Usuarios") def __str__(self): return "[{}]{}".format(self.pk, self.username) def save(self): create = True if self.id is None else False if create: self.set_password(self.password) super(CustomModel).save() And this is the serializer: class TCDUserSerializer(CustomModelSerializer): class Meta: model = models.TCDUser fields = ('id','username', 'email', 'first_name', 'last_name', 'is_staff', 'is_active', 'is_superuser', 'password', 'is_change_password', 'groups') When I send a POST to the regular DRF ModelViewSet, I get this exception: TypeError: Got a `TypeError` when calling `TCDUser.objects.create()`. This may be because you have a writable field on the serializer class that is not a valid argument to `TCDUser.objects.create()`. You may need to make the field read-only, or override the TCDUserSerializer.create() method to handle this correctly. If I remove the call super(CustomModel).save(), the exception is no more, but I need to set the password when the user is created.
