What exactly is the cause to my InconsistentMigrationHistory in Django
I've noticed that there's some question on this website about this and i've got some solution from them. but my goal with this question is to know the exact problem so I can avoid this in the future and some extra solution is fine I've had this issue after I applied my custom user model account.models.py from django.db import models from django.contrib.auth.models import AbstractBaseUser, BaseUserManager # Create your models class Account(AbstractBaseUser): email = models.EmailField(unique=True, max_length=255) username = models.CharField(max_length=255) is_active = models.BooleanField(default=False) is_admin = models.BooleanField(default=False) date_joined = models.DateTimeField(auto_now_add=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['username'] def __str__(self): return self.email fakeapp.models.py from django.db import models from django.conf import settings # from django.contrib.auth.models import User # Create your models here. class Text(models.Model): text = models.CharField(max_length=30) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) def __str__(self): return self.text for some more context before I made this custom user model I was using default User model and I've already made data stored in the Text table with it. So by best guess is that is why this error occurred. Is that true or maybe there's other things that caused this?. -
django production server allow user to access requirements.txt and other file like manage.py
I find a big security breaches server allow user to access files example: a user can access https://example.com/app_directory/requirements.txt and the worst is i can download all file.py by doing https://example.com/app_directory/site/manage.py Content-Encoding deflate can be the cause. How can i fix that? -

Django DRF unit tests added with dynamic mixins via metaclass not being executed
I am trying to test DRF endpoints, and trying to add mixings dynamically to a test in order to execute tests again each method allowed in the endpoint (get, post, put, patch, delete) So, my idea is to make a base test class that will automatically add some mixings to test endpoints if they are allowed. And I can create the actual test that will inherit from this base class. The code: from rest_framework.test import APITestCase class GetTestMixin: def test_get_all(self): response = self.client.get(self.uri) self.assertEqual(response.status_code,status.HTTP_200_OK) class AutoMixinMeta(type): def __call__(cls, *args, **kwargs): allowed_methods = ['get', 'post'] # cls would be the Test class, for example TestExample # cls.__bases__ is a tuple with the classes inherited in the Test class, for example: # (<class 'unit_tests.endpoints.base_test.RESTTestCase'>, <class 'rest_framework.test.APITestCase'>) bases = cls.__bases__ for method in allowed_methods: bases += (cls.method_mixins[method.lower()],) # Create a new instance with all the mixins cls = type(cls.__name__, bases, dict(cls.__dict__)) return type.__call__(cls, *args, **kwargs) class RESTTestCase(metaclass=AutoMixinMeta): uri = None method_mixins = { 'post': PostTestMixin, 'get': GetTestMixin, } class TestExample(RESTTestCase, APITestCase): uri = reverse('somemodel-list') I was expecting test_get_all to be executed, but it is not. Mixings are in place. I made a dummy method inside TestExample and put a debugger in place, and … -

Is there a way to force usage of the DB Router, even if some model queries have specific the database using
We have a legacy project where traditionally developers explicitly specified the database to be used like so:- Fruits.objects.using('db_xyz').filter(id__in=12,23) But now we have introduced a custom DB Router that decides the DB to be used, thus taking away the decision from every individual that writes such code. This works very well. But we still need to fix all older code to avoid passing "using", since doing this causes the DB Router to get bypassed. My question is, is there any way that we can force usage of the DB Router, even for model usage that specifies the database to be used? Basicall, the above code exists in 100s of places, and we don't want to have to fix it in all places to look like Fruits.objects.filter(id__in=12,23) -
what exactly does request.user return in django, can we compare it with a string?
I am new to Django and trying out somethings. I am thinking to return a page named "in_accessable.html" if a normal user access the "\create" page (which calls the function named medicine_create_view"), else medicine_create.html. The name of admin is "npend" so I gave a if statement to check if the user name is 'npend' or not, I used request.user method to get the user name, even if I access the page with admin I am getting a false in if statment I tried printing request.user == "npend", which prints False every time. Can anyone help me rectifing this problem, Thank You. Code Used: def medicine_create_view(request, *args,**kwargs): my_form = Raw_Medicine_Form() if request.method == 'POST': my_form = Raw_Medicine_Form(request.POST) if my_form.is_valid(): print(my_form.cleaned_data) Medicine.objects.create(**my_form.cleaned_data) else: print(my_form.errors) my_form = Raw_Medicine_Form() context ={ "form" : my_form, } #print(request.user=="npend") if(request.user=="npend"): return render(request,"App_1/medicine_create.html",context) else: return render(request,"error_files/not_acessable.html",{}) -

How to use same backend (django) api cookie to frontend(vuejs)?
I've got confusion when dealing with cookies on frontend vs backend. I've a cookie generated in backend as class JWTAuthentication(BaseAuthentication): def authenticate(self, request): token = request.COOKIES.get('jwt') if not token: return None try: payload = jwt.decode(token, settings.SECRET_KEY, algorithms=['HS256']) except jwt.ExpiredSignatureError: raise exceptions.AuthenticationFailed('unauthenticated') user = get_user_model().objects.filter(id=payload['id']).first() if user is None: raise exceptions.AuthenticationFailed("Unauthenticated") return (user, None) When i use login in frontend vuejs, a cookie is generated through api , which cookie is a also added by frontend and marked as httpOnly . I want to use same cookie without making new one in frontend. In frontend When I console.log document.cookie the generated cookie is not available , although it shows cookies generated, but at same time at backend when i access api and see console.log(document.cookie) it is available there. How can i access access that cookie even in frontend, through vuejs/javascript through document.cookie , so that i can do authentication and global guards in frontend. Thank you for helping. -

Integrate Django as a consumer with AWS Api Gateway Websockets
I'm not sure how to do it. I've looked for in almost all the network and information is not clear and confuse. I have a websocket done in AWS ApiGateway Websocket. I'm trying to connect to my websocket path from Django, the idea is to pass the information retrieved by Django to HTML to do a dynamic website. I know I can do this directly from the HTML template using javascript but, the websocket is would be open for whatever person and couldn't protect it. For that reason I'm trying to do it by Django. I've found information about channels library but the examples found are not clear due to the Websocket server used on these examples are localhost while my websocket server has a AWS path. I really appreciate your help -

Issue with Django rendering raw queryset to template
i'm pretty new to Django so still trying to understand some concepts. I'm trying to render the text from a simple CharField in a template. I would like this to be used throughout the project so i've made a context_processors.py file to handle this Models.py class HeaderCustomisation(models.Model): small_banner_text = models.CharField(blank=False, null=False, max_length=200, default="Welcome") class Meta: verbose_name_plural = 'Header Customisation' def __str__(self): return self.small_banner_text Views.py def header_customisation(request): header_customisation = HeaderCustomisation.objects.all() context = { 'header_customisation' : header_customisation, } return render(request, 'includes/header.html', context) Context_processors.py from home.views import HeaderCustomisation def header_customisation_processor(request): header_customisation = HeaderCustomisation.objects.all() return {'header_customisation': header_customisation} header.html <div id="delivery-banner" class="row text-center bg-black"> <div class="col free-delivery-wrap"> <h5 class="free-delivery-text my-1">{{ header_customisation }}!</h5> </div> </div> This renders the text from the Model but renders the raw query, like so: If anyone can help or point me in the right direction to only returning the CharField value, that would be much appreciated. Also, if any additional info is needed i'll be happy to provide. Thanks! -
