TemplateDoesNotExist: account/register.html
I am tryinging to create my own customized registration form. I already created register.html file in the templates folder, and I set the templates setting like this: TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [Path(BASE_DIR,'templates')], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] AUTH_USER_MODEL= "account.Account" This is views.py for registration_view: from django.shortcuts import render, redirect from django.contrib.auth import login, authenticate from account.forms import RegistrationForm def registration_view(request): context = {} if request.POST: form = RegistrationForm(request.POST) if form.is_valid(): form.save() email = form.cleaned_data.get('email') raw_password = form.cleaned_data.get('password1') account = authenticate(email=email, password=raw_password) login(request, account) return redirect('home') else: context['registration_form'] = form else: #GET request form = RegistrationForm() context['registration_form'] = form return render(request, 'account/register.html', context) and this is my urls.py: from django.contrib import admin from django.urls import path from personal.views import ( home_screen_view, ) from account.views import ( registration_view, ) urlpatterns = [ path('admin/', admin.site.urls), path('', home_screen_view, name="home"), path('register/', registration_view, name="register"),] I am watching this tutorial Can someone please tell me how can I solve this issue? -
add_error(fieldname, ...) in Django Rest Framework (DRF)
I have a model serializer like this: class MySerializer(ModelSerializer): class Meta: model = MyModel fields = ('myfield', 'otherfield') I need to check a cross-field condition, say, x.myfield > x.otherfield. (There are actually several otherfields and several conditions.) I need detailed and easy-to-grasp human-readable error messages. I currently generate them (actually only the first) in MySerializer.validate() via raise ValidationError(message), but then the message comes under the non-field-errors key, which is ugly and difficult for the users. It would be much nicer to attach it to myfield. In Django forms, I would use add_error('myfield', ...), but I could not find a similar thing in rest framework. What is a suitable idiom here? -

How to pass custom input field inside a form to Django CreateView and to the Model
I will keep the description as short as possible So frontend an image is compressed Via CompressorJs In HTML: <form class='form' action="" method="post" enctype="multipart/form-data"> {%csrf_token%} {{form.as_p}} <p> <input name='photo_1' id='id_photo_1' value='${base64data}'> </p> <!-- this will be created --> <button>Submit</button> </form> <div class='Uploader'> <input type="file" id="upload" accept="image/*"> </div> <script> document.getElementById('upload').addEventListener('change', (e) => { var file = e.target.file new Compressor(file, { quality: 0.5, maxWidth:910, success(result) { var reader = new FileReader(); reader.readAsDataURL(result); reader.onloadend = function() { var base64data = reader.result; var img1 = `<p> <input name='photo_1' id='id_photo_1' value='${base64data}'> <img src='${base64data}' > </p>`; $(".form").append(img1); } }, error(err) { console.log(err.message); }, }); } }); </script> In Models.py: class Card(models.Model): photo_1 = models.ImageField(upload_to='photos/cards/%Y%m/', blank=True) In Views.py: class AddCardView(CreateView): model=Card form_class = CardForm template_name='card/addcard.html' def form_valid(self, form): form.instance.poster = self.request.user return super(AddCardView, self).form_valid(form) In Form.py before: fields=(photo_1,) In Form.py after: fields=(#I removed it so the createview generated one doesn't show up in the html page) My original plan is to set the createView generated input field to hidden, Then replace the value with JS, But then I learned you can't change the value of file=input due to security reasons, The default Id and name for the CreateView generated file=input is id_photo_1 and photo_1, So I set … -
Django REST: projects vs apps
I am developing a REST API using Django Rest Framework. This API deals with a high number of resources that are divided into "business areas". I should be developing this API so that the resources from the different business areas are independent and can be used individually in contexts other than the project I am working on. My question is: should I be using different DRF projects, or different Django apps for each business area? I.e., Should I organize like this: |- businessarea1_api_project |- core_app |- api_documents |- businessarea2_api_project |- core_app |- api_documents Or like this: |- big_api_project |- businessarea1_api_app |- businessarea2_api_app I am assuming that using different apps helps me in the sense that I can use Django's reusable apps to create a package for each business area, and then I can install them in the projects they are required. Using different projects helps in the sense that i have an individual API running for each business area that can be called whenever needed, together with other APIs or not. Is this it? Are there other factors that I should be considering? Which one is better? Thank you! -
add django native authentication as the second layer of authentication, after user login via LDAP authentication
I have used Django2 to build a web app. I configured LDAP login as the auth method to login to the website. But now the client need another layer to authenticating the user logged in by LDAP. They want to map the user logged in using LDAP to the django user table, and query the user type to guide the different user to different pages.

Django sphinx docs made by cookicutter folder confusion
I'm a bit confused by the folder structure the sphinx makes for its documentation when starting a fresh new Django project with cookiecutter. I have my project set up in docker, as per instructions, everything is serving fine and I have the following folder structure for the documentation. When I run the command make html in the docs container (or by using the docker-compose local.yml file) I get the following structure. A new folder "html" is created and it's containing everything from the surrounding folders. Is this correct? Am I understanding the process correctly? For me, it looks like some bad settings for some source folder somewhere. I'm an experienced python dev, familiar with Docker as well, but I'm pretty new to Django and sphinx. Can somebody please guide me to the right path, possibly share their Django sphinx docs workflow? Thank you very much. -
