Django: Can't get the GET response value - AttributeError: module 'django.http.request' has no attribute 'GET'
I'm trying to build a simple app that collects data on shoes and then displays it as a list. I want to use pagination, which is pretty simple using Django's paginator. My problem is that I cannot get Django to give me the value sent in a GET request. According to Django docs what I have been doing should work. I've tried it with request and HttpRequest and every time I get a a "no attribute" error. The following is the code I have in my views.py file. from django.views.generic import ListView from django.http import HttpRequest, request from .models import Shoes class ShoeListView(ListView): model = Shoes template_name = 'shoes/shoes-list.html' context_object_name = 'shoes' if request.method == "GET": shoespp = request.GET['shoespp'] else: shoespp = 2 paginate_by = shoespp And this is my template. <body> <h1>Shoes</h1> <h2>List of Shoes</h2> <form method="get"> <select name="shoespp"> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> </select> <input type="submit" value="List Shoes"> </form> <ul> {%for pair in shoes %} <li> <strong>{{ pair }} <em>{{ pair.brand }}</em></strong> <em>{{ pair.colorway }}</em> - {{ pair.size }} </li> {% endfor %} </ul> <p> {% if page_obj.has_previous %} <a href="?page=1"><button>&laquo; first</button></a> <a href="?page={{ page_obj.previous_page_number }}"><button>previous</button></a> {% endif %} <span> Page {{ page_obj.number }} of {{ page_obj.paginator.num_pages … -

Push notifications from Django backend to iOS/Swift frontend
I'm in a hairy situation and not sure how to proceed. We needed to implement django push notifications for this project. I did research into the best library to use. django-push-notifications (https://github.com/jazzband/django-push-notifications) looked like the most up-to-date library to use. The APNS portion is built on apns2 (https://github.com/Pr0Ger/PyAPNs2) I did have to make a few modifications for BE testing. I essentially set up the project to do everything correctly on my end and then "pretend" to send a push notification to apple. At this stage the handshake didn't occur between django and apple. During testing a self-signed certificate is used just to make apns2 happy. Because heroku doesn't allow file uploads I had to do something a bit tricky to load the certificate into a file in django (basically reading from an environment variable and writing it to a file). Only recently did it hit me that the FE dev handed me just a private key, not a certificate. django_push_notifications requires a certificate. He further told me Apple discontinued certs in 2019 and only uses private keys. django_push_notifications didn't have any issues on the matter. [however, I did notice this page in the documentation: https://github.com/jazzband/django-push-notifications/blob/master/docs/APNS.rst] Generation of an APNS PEM … -
Use Django models.FileField to read file from memory and discard it before it is written to the directory
How can I read a file using Django's models.FileField, handle the data in memory, and then discard it before django tries to save/write it to my directory.

Django Rest Framwork PUT request to user model endpoint
I'm trying to update my user model by adding a profile picture. I'm stuck on the fact that DRF requires a lookup for PUT requests. But the client doesn't know the user pk they just have a login token. The user would normally be obtained in a view using request.user views.py: class UploadViewset(viewsets.ModelViewSet): queryset = User.objects.all() serializer_class = serializers.ImageUploadSerializer parser_classes = [MultiPartParser] models.py class User(AbstractUser): profile_image = models.ImageField(upload_to='testuploads/', null=True) serializers.py class ImageUploadSerializer(serializers.ModelSerializer): class Meta: model = User fields = ( 'profile_image', ) Posting give the following "detail": "Method \"PUT\" not allowed.", Which is caused by the fact that there is no individual resource identifier in the URL. Of course, the resource (a user) could be obtained from the request because it is an authenticated request. How can I update the user model using DRF? -

How do you migrate a custom User model to a different app in Django?

What's a good shared hosting for django app?
I am looking for a hosting for my Django webapp. It's a very simple website but it may grow in the future. I know everybody says it is not a good idea to get a shared hosting for django and that I should get a VPS. But the VPS I've found are way too expensive for me, also they might be too big for the size of my project. Any shared hosting recommendations for a small Django project? I know there are some questions about this on StackOverflow already but the ones I've read may be outdated. -

How to include Address Model in Profile Model (Django)
I am struggling with how I should structure my application and some things are not working as expected. What I am working on is a form that is supposed to let a user set a billing (possibly also a shipping) address. Unfortunately, if I include the option billing address in the profile form, it lets the user choose from all addresses in the database, also from other users. If I omit this, the address that the user enters gets saved in the database, but it is not connected to the user, and every time the user updates the form it saves the address again. What I want is: Address gets saved in relation to the user Addresses are not redundant Users shouldn't be able to see the address of another user I will attach the snippets that I think are relevant below. I am not sure if and how to change the views function in order to save the input from the billing address in relation to my user or if I should change the models, which I would rather avoid because I want to keep them simple. forms.py ... class ProfileEditForm(forms.ModelForm): date_of_birth = forms.DateInput() class Meta: model = Profile … -
How can I treat allauth password reset as email verification?
My system is already aware of the users' email addresses. When a user signs up, they get an error message from allauth: A user is already registered with this e-mail address. I advise users to reset their password when they see this message. However, once they've reset their password, allauth triggers the email address confirmation flow, since ACCOUNT_EMAIL_VERIFICATION = True. It is inconvenient and unneccessary for the user to also do email validation at this point. How can I avoid email verification in this scenario? -

Running Django tests without collect static
I am trying to run a test suite for django that uses inlinecss. inlinecss references a static file in the template as follows: {% load inlinecss %} {% inlinecss "css/emails/base.css" %} When running in Debug mode this works fine, when running in production (having run collectstatic) this also works fine. However when running tests (without running collectstatic before) I get the following: FileNotFoundError: [Errno 2] No such file or directory: '/app/project-name/staticfiles/css/emails/base.css' This makes sense as django is looking for the file in STATIC_ROOT (STATIC_ROOT = os.path.normpath(join(os.path.dirname(BASE_DIR), "staticfiles"))) I am wondering if there is a way to allow Django to access this file without having to run collectstatic? It would be ideal if I could add some settings to test.py so that it could collectstatic to a tmp directory or not require collectstatic at all (like when running in debug mode) but I have had no success trying this. I am using pytest to run tests. -

Here is my view: def show_map(tuple_lat_lon, name): start_coords = tuple_lat_lon[0] folium_map = folium.Map( location=start_coords, zoom_start=14 ) folium.CircleMarker( tuple_lat_lon[0], radius=8, popup=name, color='#3186cc', fill=True, fill_color='#3186cc' ).add_to(folium_map) folium.Polygon(tuple_lat_lon).add_to(folium_map) buffer = io.BytesIO() plt.savefig(buffer, format='png') buffer.seek(0) image_png = buffer.getvalue() buffer.close() graphic = base64.b64encode(image_png) graphic = graphic.decode('utf-8') return graphic farm_map = show_map(tuple_lat_lon, 'MyMap') return JsonResponse({ 'farm_map':farm_map, }) Here is my d3.js code: var farm_map = block_details_response['farm_map']; d3.select('#block_map').append('img').attr('src', farm_map); here is the html: <div id="block_map"></div> I can see when I inspect html, the image code...but not the image. So I want to know: Is it a good idea to send folium map in response? I did it cause I call a lot of my own apis on the web page. As tutorials suggest, this the way to show the map:{{ farm_map | safe }} . I can't do that since I am using d3.js . Essentially javascript. I tried d3.select('#block_map').append('img').attr('src', farm_map + '|safe'). Did not work. Any ideas suggestions are welcome -
Get a javascript element by ID from select and pass to Django url
I have select options and I want to send the value to a url offside the form (because I'm using a image as a link). html: <form action="" method="GET" id="maintenanceForm"> <div class="form-group col-md-4"> <label for="assigned" style="font-size:medium;">Assigned</label> <select class="form-control" id="assigned" name="assigned"> <option value=""></option> <option value="a.takao">André Takao</option> <option value="adam.m">Adam William</option> <option value="alex.matos">Alex Matos</option> </select> </div> </form> <a href="{% url 'maintenance_issue_validation_approved' %}?id={{ maintenance_issue.id }}&assigned=assigned"> <img src="{% static 'images/icons/approved.png' %}"> </a> <script> var assigned = document.getElementById('assigned').value; return assigned; </script> views: def maintenance_issue_validation_approved(request): if request.method == 'GET': issue_id = request.GET.get('id') assigned = request.GET.get('assigned') print(assigned) How to get the "assigned" select value and send it to my view? The expected value is, print the selected assigned value: for example: adam.m
