Django Fixing UnicodeDecode Error Decoding
I am following a Django CRUD tutorial and am getting this error when I try and load my url. The rest of my views all work except this one, and I've never seen this error before. I googled similar issues and found a few proposed solutions (posted below) but nothing has worked on my end. Any ideas how to fix this? I have already tried adding from __future__ import unicode_literals and def __str__(self): return "(%s)" % self.name into my views.py file with no luck 'utf-8' codec can't decode byte 0xd7 in position 2046: invalid continuation byte html {% extends 'base.html' %} {% load static %} {% block title %}Django Ajax CRUD{% endblock %} {% block content %} <div class="container"> <h1>Django Ajax CRUD</h1> <div class="row"> <div class="col-md-4 "> <h3>ADD USER</h3> <form id="addUser" action=""> <div class="form-group"> <input class="form-control" type="text" name="name" placeholder="Name" required> </div> <div class="form-group"> <input class="form-control" type="text" name="address" placeholder="Address" required> </div> <div class="form-group"> <input class="form-control" type="number" name="age" min="10" max="100" placeholder="Age" required> </div> <button class="btn btn-primary form-control" type="submit">SUBMIT</button> </form> </div> <div class="col-md-8"> <h3>USERS</h3> <table id="userTable" class="table table-striped"> <tr> <th>Name</th> <th>Address</th> <th colspan="3">Age</th> </tr> {% if users %} {% for user in users %} <tr id="user-{{user.id}}"> <td class="userName userData" name="name">{{user.name}}</td> <td class="userAddress userData" … -
Running Django with gunicorn (on a K8s node created from a Docker Image) produces poor performance and CORS errors

Mock a test with a external api rest in Django Rest Framework
Context I am developing an API Rest with Django Rest Framework, and some of my endpoints consume an external API Rest to create a model instance, the code works but right now I am trying to test my code but I have very struggled with that.

Is there any way to organize filelds in django models?
I have many tables in my django models, each responsible for a different form in my template. I wrote some code to convert this fields directly into tempalte using python and JavaScript. Next I've been trying to add sections into template, which means that in my template each section has own title and own fields. After a few tries my code looked like an example: #before class forms_n(Models.Model): field1 = models.IntegerField() field2 = models.ForeignKey(ForeignModel, on_delete=models.CASCADE,null=False,blank=False) field3 = models.IntegerField() field4 = models.IntegerField() #after class form_n_cfg: @section_decorator(section=0,title="This is seciton 0") class form_n_0(models.Model): field1 = models.IntegerField() field2 = models.ForeignKey(ForeignModel, on_delete=models.CASCADE,null=False,blank=False) class Meta: abstract = True @section_decorator(section=1,title="This is seciton 1") class form_n_1(models.Model): field3 = models.IntegerField() field4 = models.IntegerField() class Meta: abstract = True class form_n(forms_n_cfg.form_n_0,forms_n_cfg,form_n_1): pass #utils.py def section_decorator(**kwargs): def set_attrs(obj): fields = obj._meta.fields for i in fields: for key,value in kwargs.items(): setattr(getattr(obj,i.name),key,value) return obj return set_attrs Everything worked fine, in time I realized that Foreignkey unlike other fields doesn't have any values from my decorator. I think the problem is because i added attrs to for parent class, not subclass form_n which i use (just why other fields had values from decorator). I noticed that just classes inner form_n_cfg has @section_decorator attributes for … -

Django: models setup for using one database to populate another
I'm rebuilding a personal project in Django, (a family tree), and I'm working on migrating the actual data from the old awkward database to my new model/schema, both Postgres databases. I've defined them in the DATABASES list on settings.py as 'default' and 'source'. I've made my models and I'd like to copy the records from the old database into their corresponding table in the new database, but I'm not quite understanding how to set up the models for it to work, since the Django code uses the models/ORM to access/update/create objects, and I only have models reflecting the new schema, not the old ones. In a coincidental case where I have a table with the exact same schema in the old and new database, I have a management command that can grab the old records from the source using my new ImagePerson model (ported_data = ImagePerson.objects.using('source').all()), since it the expected fields are the same. Then I save objects for them in the 'default': (obj, created_bool) = ImagePerson.objects.using('default').get_or_create(field=fieldvalue, etc), and it works just like I need it to. However when I have a table where the old version is missing fields that my new model/table have, I can't use the model … -

Cannot login my DRF dashboard using simpleJWT, it only works when SessionBased authentication is used (I don't want SessionBased auth)
I have a django project that uses 'rest_framework_simplejwt.authentication.JWTAuthentication' as the default authentication class. To my understanding this is a stateless token that does not use SessionAuthentication. In my DRF home screen (the default dashboard created by drf), I'm trying to log-in, using the top-right button on the screen, however it's not working. Here is the error I get: { "detail": "Authentication credentials were not provided." } After testing, said login button only works when SessionAuthentication is the default class and path('home-auth/', include('rest_framework.urls', namespace='rest_framework')) is placed in my global urls.py. I read about scalability issues when having a Session based auth system, so I would like to refrain from using it. I have created an app, users, that has it's own login URL serializer/view, and uses the JWT authentication method, it works just fine without errors. I thought that method would be the default login verification method that DRF would use but that is not the case due to the error above. I can login just fine when I use my users login url. settings.py INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'drf_yasg', # Third Party Apps #'admin_honeypot', 'rest_framework', 'django_filters', 'corsheaders', 'rest_framework_simplejwt.token_blacklist', # Apps 'users', ] REST_FRAMEWORK = { … -
Django allow user to edit information
I am trying to allow users to update their profile information but nothing happens upon submit. I thought I had every part covered but clearly missing something.

A quick question regarding threading module in Django?
I'm building a scrapper that crawls through URLS and finds emails. I've found out that threading can make this crawling process faster and I'm trying to implement it on Django. But there is a lot of information lacking in regards to this module. One quick question I would like to ask is how would someone know if threading is running correctly on Django. Would this code be enough to run threading? from django.shortcuts import render from django.shortcuts import render from .scrapper import EmailCrawler from django.http import HttpResponse from celery import shared_task from multiprocessing import Process import threading def index(request): return render(request, 'leadfinderapp/scrap.html') t = threading.Thread(target=scrap) t.start() def scrap(request): url = request.GET.get('Email') crawl = EmailCrawler(url) target = crawl.crawl() email_list = crawl.emails # or whatever class-level variable you use return render(request, 'leadfinderapp/results.html', {"email_list": email_list}) Thank you very much any help I would really appreciate it. -
Django templates: if .. in
I have a list of products and want to display them in a template, depending on whether or not the product's dealer is "owned" by the current logged user or not. So here's my view: class ArticleListView(ListView, LoginRequiredMixin): template_name = "accounts/list_article_quentin.html" model = Product def get_context_data(self,**kwargs): context = super().get_context_data(**kwargs) context["website"] = Website.objects.first() context["product_list"] = context["product_list"].filter(published=True) # Get a list of all dealers associated to the current users. currentUserDealers = self.request.user.dealers.all().values_list('id', flat=True) context["current_user_dealers"] = list(currentUserDealers) return context so currentUserDealers is the list of the dealers associated to the current user (It's a ManyToMany relationship between dealers and users). In my template, I would like to do something like that to decide wether to display the product or not: {% if product.dealer.all.0.pk in current_user_dealer %} (there can be multiple dealers for a product but I'll see that later, hence the all.0) Obviously this doesn't work but you get the idea, I want to see if the current product's dealer ID is in the list of current user's associated dealers, to see if we display it or not. What's the syntax to do it in the template? Or maybe there's a better way to do this directly in the view? -

How to check if a user is logged in, in django token authentication?
Hi there I am currently starting a new rest api project with django. Normally when I start a new project I do a lot of planning and get a idea of how I want to build my app. For this app I want to use token authentication but can't find enough resources for this topic. Can anyone tell me these two things, how to check if a user is logged in/authenticated and how to check which user is logged in(of course with token authentication in django). Thank you in advance. Extra info(you don't need to read this): The reason I want to use this kind of authentication is because I don't want to use the built in django models for my user model because my User model has to have some specific fields for this web app, obviously I can work my way around this but its not very efficient so I figured I'd use token authentication. -

Add form fields programmatically to Wagtail Form
I have a model which subclasses AbstractEmailForm.. I can create a new instance with: new_page = LanderPage(body='body text here', title='Test sub page', slug='testsub', to_address='j@site.com',from_address='j@site.com', subject='new inquiry') This works, but it produces a form without fields. I am not sure how to create the form fields using this structure, such as the form field for name and email address. Can someone point me in the right direction? For reference, this is the page being created: class LanderPageFormField(AbstractFormField): page = ParentalKey('LanderPage', related_name='form_fields') class LanderPage(AbstractEmailForm): body = RichTextField(blank=True) thank_you_text = RichTextField(blank=True) content_panels = AbstractEmailForm.content_panels + [ FieldPanel('body', classname="full"), InlinePanel('form_fields', label="Form fields"), FieldPanel('thank_you_text', classname="full"), MultiFieldPanel([ FieldRowPanel([ FieldPanel('from_address', classname="col6"), FieldPanel('to_address', classname="col6"), ]), FieldPanel('subject'), ], "Email"), ] -
How to embed a form multiple times with ListView (and once with DetailView)
I have the following listview and detailview structure. I would like to pass in a form to be shown with each object that is listed in the listview (and also with the one object when there is detailview). How can I get this to show up with each object? class ObjectListView(LoginRequiredMixin, ListView): model = Object ... date = (datetime.now() - timedelta(hours = 7)).date() queryset = Object.objects.filter(date=date) def get(self, request, *args, **kwargs): ... return super().get(request, *args, **kwargs) class ObjectDetailView(LoginRequiredMixin, DetailView): model = Object -
fetching data from backend with certain email address react native
I am having trouble trying to fetch only certain data entries from my backend with a specific email address. My backend stores data from multiple user but lets say I want to fetch only the data from johndoe@gmail.com rather than just fetching all the data. How would I go about putting a condition like that. Below is the code I am using to fetch data from my backend. fetchDataFromApi = () => { const url = "http://localhost:8000/api/list/"; fetch(url).then(res => res.json()) .then(res => { console.log(res) this.setState({myListData: res}) }) .catch(error => { console.log(error) }) }; So from the code, I am basically getting all the data and storing it into the state called myListData but I want to only store data for johndoe@gmail.com. Is there any where I can go about achieving this? Thank you in advance!
