In order to discontinue 3rd party API access, allow to create or reset a password in python-social-auth for already registered users via 3rd part
There are certain 3rd party sites that have a daily cap for API user requests. Case in point, Linkedin which only allows 100k requests a day. Imagine your site grows so much that this wall is hit. I believe the next step would be to disable the linkedin connectivity and only allow via regular email and password. The problem is those users that signed in initially with linkedin - with what password can users try to log in using their regular emails? I've also attempted resetting a password as a user that logged in via linkedin through the reset password default django flow (tokenized link sent to their email) and the link does not even print in the console. However, when I do these steps as a user that signed in with a regular email and password, the workflow works well. What would be the steps to allow for a "resetting" for these users? PS. I wonder if it can be something via the below logic... https://python-social-auth.readthedocs.io/en/latest/backends/username.html Thanks in advance. -
Intermittent Bad Request (400) Spotify API callback using nginx + gunicorn + django
When I use nginx to serve my spotify django app with gunicorn socket handling communication, I would sometimes get Bad Request error during the user authentication callback. If gunicorn is configured as TCP with an ip and port, I don't experience the error, nor if I use django's manage.py runserver; user authenticates successfully. This intermittent issue seems to only occur when I'm using a socket connection. Checked nginx, gunicorn and django logs and didn't really get any info other than the 400 code. Using tekore python library to access spotify's api. Here's my nginx config: upstream app_server { server unix:/home/yg/Documents/projects/app/run/gunicorn.sock fail_timeout=0; } server { listen 80; server_name 192.168.0.26; client_max_body_size 4G; access_log /home/yg/Documents/projects/app/logs/nginx-access.log; error_log /home/yg/Documents/projects/app/logs/nginx-error.log; location /static/ { alias /home/yg/Documents/projects/app/static/; } location /media/ { alias /home/yg/Documents/projects/app/media/; } location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_redirect off; proxy_buffering off; if (!-f $request_filename) { proxy_pass http://app_server; break; } } # Error pages error_page 500 502 503 504 /500.html; location = /500.html { root /home/yg/Documents/projects/app/static/; } } -
I need to access a foreign Key element for populating a ModelForm
I'm building a forum with comment and Reply capabilities. While populating the form I'm facing a issue of Cannot assign "<Post: Post object (10)>": "Reply.comment" must be a "Comment" instance. I can understand the problem but don't know how to morph it into a Comment Instance.

Can't send POST request from react method
I am creating a FB like app with Django and react. In the main page there's a feed where users can create posts and post them to the feed.

How to filter out objects in a related model without filtering out any of the objects from the primary model [Django]

How to add Chart.js to Wagtail Homepage panels using construct_homepage_panels hook?
I'm modifying the main dashboard of my Wagtail app to provide more useful/relevant data such as the number of open work orders, or number of customers. I am having some trouble getting my Chart.js to display in my dashboard. I've confirmed that the resource chart.js (version 2.8.0) is loading, and my canvas element is loaded onto the page as well.

Where can I publish node and python development projects?
I may soon want to find work as a full stack developer either with a company or as a free-lancer. What hosting service would be capable of running node and python (in addition to PHP and MySQL) so that I can use frameworks to create a front end. I don't want to spend hundreds of dollars a month, but I can't use some hosting sites that only allow static websites (e.g. BlueHost, which doesn't let you use node.js). I think AWS or A2 may be an option, but again, I don't want to have to pay too much. And I certainly don't want to use WordPress. I want to build things from scratch. -

How to display self-joined fields in Django?
I'm trying to build a comment section to a social-media-esque web app I'm building. I have a datatable storing comments using Django, and would like to build in a reply feature. Here is my model: class Comments(models.Model): id = models.AutoField(primary_key=True) text = models.TextField() author = models.CharField(max_length=50) creation_time = models.DateTimeField(auto_now_add=True) answer = models.ForeignKey(Answers, on_delete=models.CASCADE) replyto = models.ForeignKey('self', null=True, on_delete=models.CASCADE) def __str__(self): return self.author + ' commented: ' + self.text Essentially, whenever someone replies to a previous comment, I'd store that previous comment's ID in the "replyto" field, with which I'd like to link the current comment to that previous comment. In getting the current comment from the view I set up, I'd like to get all fields of the current comment (as outlined above) as well as the text and author of the previous comment (i.e. comment being replied to). In base SQL, I'd figured this would be a bit of self join logic. How do I do this in Django (and show the additional text and author fields of the being-replied-to comment as described above)? Thanks! -
Django inline model formset and inline model form handle initial differently
I'm using a StackedInline to populate a OneToOneField, but I want to make it optional, so I set min_num=0 and extra = 0. I also want to include default values when the user presses the "➕ Add another" button. class MyForm(forms.ModelForm): def __init__(self, *args, **kwargs): kwargs['initial'] = {'hello': 'world'} class MyInline(admin.StackedInline): form = MyForm extra = 0 min_num=0 This works. When someone presses the "➕ Add another" button, the hello field is populated with world. I also want to and do some custom validation, so it looks like I have to use BaseInlineFormSet. I moved the initial stuff to MyFormSet.__init__ class MyFormSet(BaseInlineFormSet): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) if not self.forms: return self.forms[0].fields['hello'].initial = 'world' def clean(self): # My custom validation class MyInline(admin.StackedInline): formset = MyFormSet extra = 0 min_num=0 But the initial values are no longer populated when the user presses the "➕ Add another" button, only when the form is initially displayed with extra = 1. Is there another thing I need to do in MyFormSet to preserve the MyForm behavior? -

Joining tables in a nested serializer in django?
I am kind of at my wits end here. Been searching for hours but i can't wrap my head around it. I have the following models: class Word(models.Model): sentence = models.ForeignKey(Sentence) vocabulary = models.ForeignKey(Vocabulary) class Sentence(models.Model): text= models.ForeignKey(Text) class Text(models.Model): ... class Vocabulary(models.Model): ... class VocabularyStatus(models.Model): vocabulary = models.ForeignKey(Vocabulary) user = models.ForeignKey(User) status1 = models.IntegerField(default=1) status2 = models.IntegerField(default=1) My desired output is in the form of: text = { "sentences": { "words": { "id": 1 "vocabulary": 1 "status1": 1 "status2": 1 } } } So basically the hirarchy is Text > multiple sentences > multiple words. And the status is different based on the user who is doing the query. The reason why Vocabulary is different from Word is because multiple words can have the same vocab (e.g uppercase/lowercase words) Serializers: class TextSerializer(serializers.ModelSerializer): sentences = SentenceSerializer(many=True) class SentenceSerializer(serializers.ModelSerializer): words = WordSerializer(many=True) class WordSerializer(serializers.ModelSerializer): ... With the queryset: queryset = Text.objects.prefetch_related('sentences', 'sentences__words') It works fine for that. But i have no idea how to link the data from VocabularyStatus into that. It is already a nested serializer. I tried: queryset = Text.objects.prefetch_related('sentences', Prefetch('sentences__words', Word.objects.prefetch_related('vocabulary__vocabularystatus_set'))) But now i have no idea how to filter for the user with that or how to … -
Task schedules for django database in python
Im starting a web app with a mongo database. I want to update this database every 5 minutes so the users can have the newest data available. Before i started with django, i used crontab to execute my crawling scripts in an external server and update automatically my DB. However, ive read that it is better not to use cron with django because it should only be applied to system operations and it is not portable. What task scheduler is the best for django? Some posts suggest Celery and some others suggest RQ. Which is the way to go? Thank you in advance. -

How am I able to pass recipe's pk to be able to back to previous view? models.py class Recipe(Timestamp): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, unique=True) title = models.CharField(max_length=100, unique=True) preparation = models.TextField() def __str__(self): return self.title class Ingredient(Timestamp): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, unique=True) recipe = models.ForeignKey(Recipe, on_delete=models.CASCADE) name = models.CharField(max_length=100) amount = models.PositiveSmallIntegerField(blank=True, null=True) unit = models.ForeignKey('Unit', on_delete=models.SET_NULL, blank=True, null=True) def __str__(self): return self.name views.py class RecipeView(generic.DetailView): model = Recipe context_object_name = 'recipe' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['ingredients_list'] = Ingredient.objects.filter(recipe=self.object.pk) return context class AddIngredientView(generic.edit.CreateView): model = Ingredient fields = [ 'name', 'amount', 'unit' ] success_url = '/' template_name = 'recipes/add_ingredient.html' def dispatch(self, request, *args, **kwargs): self.recipe = get_object_or_404(Recipe, pk=self.kwargs['pk']) return super().dispatch(request, *args, **kwargs) def form_valid(self, form): form.instance.recipe = self.recipe return super().form_valid(form) def get_success_url(self): if 'add_another' in self.request.POST: url = reverse_lazy('recipes:add_ingredient', kwargs={'pk': self.object.recipe_id}) else: url = reverse_lazy('recipes:recipe', kwargs={'pk': self.object.recipe_id}) return url add_ingredient.html {% extends "base.html" %} … -
Django: Unable to login with user
When I have registered a user, they get redirected to the login-page but I seems that my error message triggers which means that my login function is not working properly working. Any suggestions what I'm doing wrong, it worked well before. My function in views.py def LoginUser(request): if request.method == "POST": email = request.POST.get('email') password = request.POST.get('password') user = authenticate(request, email=email, password1=password) if user is not None: print(user) login(request, user) return redirect('/start.html') else: messages.info(request, 'Incorrect user details') context = {} return render(request, "/login.html", context) My forms.py from django.contrib.auth.forms import AuthenticationForm, UserCreationForm from django.contrib.auth import login, authenticate from django.contrib.auth.models import User from django import forms from .models import Account, MyAccountManager class RegisterForm(UserCreationForm): #firstname = forms.EmailField() #lastname = forms.EmailField() email = forms.EmailField(required=True) class Meta: model = Account fields = ["email", "password1", "password2"] -
How to manually clear DB in a Django test?
I am using: python = "3.8.3", django="3.0.5" I have written a django test with APITestCase. I am running other tests inside my test class. I am trying to call other functions inside my test class. In order to do this I have a dictionary in a list which i mapped like this: [ { "class_name": class_name, "func_name": "test_add_product", # Comes test name "trigger_type": trigger_type, # Comes from model choices field. "request_type": RequestTypes.POST, "success": True, }, { ... }, ] I am looping these with a for loop and running each one. After each loop db should be cleared in order to not get error. I tried to do this using: # Lets say that, we have a Foo model Foo.objects.all().delete() This method works, but I want a better solution. How can I manually clear the test db before the test finishes?
