Unity Web Request + Django: CSRF token missing or incorrect
I am receiving an error from Django that the "CSRF token is missing or incorrect" along with its standard error message. Many other questions have covered the right response when you're working with a standard browser and a Django server, but I'm trying to get UnityWebRequest to play nicely with Django. Conceptually, I have two steps. First, I'm calling a GET request on my login page, parsing out the csrfmiddlewaretoken from my form, and the csrftoken from the set-cookie header. Then, I make a second UnityWebRequest that includes the "referer" as a header and the csrftoken as a header in the cookies. I would add in to the form the username and password and csrfmiddlewaretoken, but the error is present either way. Are there other headers or cookies to set? I assume my trouble is that I'm trying to emulate the behavior of a web browser in Unity, and that's complicated. UnityWebRequest loginPage = UnityWebRequest.Get("https://dividedsky.herokuapp.com/accounts/login/"); yield return loginPage.SendWebRequest (); if(loginPage.isNetworkError || loginPage.isHttpError) { Debug.Log(loginPage.error); yield break; } // get the csrf cookie string SetCookie = loginPage.GetResponseHeader ("set-cookie"); Debug.Log (SetCookie); Regex rxCookie = new Regex("csrftoken=(?<csrf_token>.{64});"); MatchCollection cookieMatches = rxCookie.Matches (SetCookie); string csrfCookie = cookieMatches[0].Groups ["csrf_token"].Value; // get the middleware value string … -

Automatically show the foreignkey's other fields in django
I am trying to show the field(s) related to its foreignkey on html. Let's see I have two models as shown below: models.py from django.db import models class Model_Item(models.Model): item_name = models.CharField(max_length = 20, null = False, blank = False, unique = True) item_unit = models.CharField(max_length = 20, null = False, blank = False) # can be kilogram, pound, ounce, etc def __unicode__(self): return self.item_name class Model_Weight(models.Model): item = models.ForeignKey(Model_Item, to_field = "item_name") item_weight = models.FloatField(null = True, blank = True) def __unicode__(self): return self.item On Model_Item model, each item can have its own unit, and there can be many items. Then when we choose the item on the second model (Model_Weight), we will insert the value of the weight that is according to its unit. How can we show the corresponding "item_unit" in html, such that when we have selected the "item_name", its unit will show/hover somewhere in the webpage which enables us to put the correct weight value? These are the rest of the codes: forms.py from django import forms from .models import Model_Weight class Form_Weight(forms.ModelForm): class Meta: model = Model_Weight fields = ["item", "item_weight"] views.py from .models import Model_Weight from .forms import Form_Weight from django.views.generic import CreateView … -
How to save multiple html inputs with the same name in django?

Why my python docstring is not recognised?
I'm trying to create docstrings for a class method in django models. The method itself does not matter, it has the following structure: def my_function(self, param1, param2): """My function does this and that. params: param1: something param2: something else """ if param1 == param2: return param1 else: return param2 When in Django shell_plus I run MyClass.my_function.__doc__ it returns nothing, same happens when I try to access docstring via instance or through help(MyClass.my_function) Suggestions on what could be wrong with the docstrings and how to make them work much appreciated. -
gunicorn ImportError: No module named django_jalali
I'm running a project using django, nginx and gunicorn which works fine on local machine. When I moved the project to the server and installed everything, I tested the project using python3 manage.py runserver and it works fine.

Django: Hidden/Orphaned oneToOneField values
When I run in manage.py shell qs = UserProfile.objects.all(); qs.count() I get 18 instances. However, when I look at my webpage's admin, under UserProfile, I only see 6 users. I can loop through the users and print the full namefor i in qs: print(i.user.full_name) it prints the first 6's full name and then errors out with this error: AttributeError: 'UserProfile' object has no attribute '_user_cache' I think I have some (12) items in UserProfile that are not linked to a user profile. They don't show up in the admin and so I don't know how to delete them. Does anyone know how I can delete them from the command line or why they may be there in the first place? I'd like to not have orphaned items like these. Each one should relate to a user. It should at least show in the admin tab! models.py class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) class User(AbstractBaseUser): ... -

Django Search form not submitting value

How can i correctly pass kwargs to RedirectView from django login to redirect to user profile?
I am having a problem with having a user login and then redirect to the correct profile. Each user has a profile. Each profile has a dashboard. Using django's built-in login, I want to redirect the newly authenticated user to a url like this: example.com/profile/dashboard/. I can't make this work because I cannot figure out how to pass the kwargs between the django login view and my detailview. In between, there is a redirectview. Can someone show me how to do this? models.py class Profile(TimeStamped, Slugged): user = models.OneToOneField(User, on_delete=models.CASCADE) def __str__(self): return self.user.username def save(self, *args, **kwargs): super(Profile, self).save(*args, **kwargs) self.slug = (slugify(self.user.username)) def get_absolute_url(self): return reverse('profiles:detail', kwargs={'profile': self.slug}) class Dashboard(TimeStamped, Slugged): profile = models.OneToOneField(Profile, on_delete = models.CASCADE) uuid = models.UUIDField(default=uuid.uuid4) def __str__(self): return self.profile.user.username def save(self, *args, **kwargs): super(Dashboard, self).save(*args, **kwargs) self.slug = (slugify(self.uuid)) def get_absolute_url(self): return reverse('profiles:dashboard', kwargs={'profile': self.profile.slug, 'dashboard': self.slug}) views.py class DashboardRedirectView(LoginRequiredMixin, RedirectView): permanent = False query_string = False pattern_name = 'profiles:dashboard' def get_redirect_url(self, *args, **kwargs): dashboard = get_object_or_404(Dashboard, slug=kwargs['dashboard']) return super().get_redirect_url(*args, **kwargs) urls.py urlpatterns = [ path('profiles/home/', DashboardRedirectView.as_view(), name = 'home') ......... -
Django allauth got an error is_safe_url() got an unexpected keyword argument 'allowed_hosts'

Django Query by State Name instead of 2 char abbreviation
I have a model that has a MULTISELECTFIELD where the user can select which states relate to them. It uses django-localflavor in the backend and so on the form they choose 'TEXAS' and 'TX' is stored on the database. I'm using this Q query to find the users that are associated with a state. Q(states__icontains=query) But this only returns a success for 'TX' and not 'TEXAS'. That makes sense since that is how it is stored in the database, but how can I search by Texas and get the same return? All I can think of is to go to the Class Manager (myclassManager(models.Manager) and create a get_state_name method that takes in a 2 digit code and returns the state name. If that is the case, I have to make a dictionary with the list by hand. I feel like the could be a cleaner way. Thoughts? -

Storing data files for Heroku Django app on S3
I am attempting to deploy a web demo for a trained neural network on Heroku. I am having some trouble with this because the underlying Tensorflow model that needs to be loaded is about 900MB, which is too large to deploy in a Git commit with the code. I need a way to deploy this model file along with my code because of Heroku's ephemeral file system. I hacked together a solution where, only on the first received request, the server downloads the model files from an Amazon S3 bucket. I through this code in the body of the Django views.py file. However, this still isn't working because the first request is timing out on the Heroku server. Is there anywhere else I can put this code or a cleaner way to approach the problem? -
