Adding a field to custom Django Form Field
I just need one custom extra attribute in my Django form fields which is icon. I will take the example of my custom CharField. custom_fields.py: class ICharField(forms.CharField): """ Django CharField with custom icon field to use along with Bulma. """ icon = '' def __init__(self, *, icon='', max_length=None, min_length=None, strip=True, empty_value='', **kwargs): super().__init__(**kwargs) self.icon = icon forms.py: from utils.forms import custom_fields class SignUpForm(forms.Form): company_name = custom_fields.ICharField( icon='fas fa-envelope', widget=forms.TextInput(attrs={ 'class': 'input', 'placeholder': _('Name of your company'), 'label': _('Company'), }) ) That's it, but when in the HTML I try to access to {{ field.icon }} I'm getting nothing. the.html: {% extends 'template_composition/main.html' %} {% load i18n %} {% block content %} {% for field in form %} <div class="field"> <b>{{ field.label }}:</b> <p class="control has-icons-left"> {{ field }} <span class="icon is-small is-left"> <i class="{{ field.icon }}"></i> </span> </p> </div> {% endfor %} {% endblock %} It's obvious I'm overriding __init__ wrong, right? -

Using CSRF in an AJAX Call causes Uncaught TypeError: Cannot read property 'value' of null
I am struggling to figure out why my code is returning an error that is being caused by using CSRF in an Ajax call.

Django cyclic imports and typechecking with mypy
I'm trying to create a simple custom manager with one of my Django models. It causes a cyclic import since I'm trying to import the manager from models.py and the model from managers.py. However, because my manager is creating the model and adding some extra attributes, the type hint for the method is the model instance. I'm having trouble with fixing that type hint since it's not yet imported. # models.py from .managers import PublishedBundleManager class PublishedBundle(models.Model): data = JSONField() md5_checksum = models.CharField(max_length=128) objects = PublishedBundleManager() The manager has a method to help me create the model instance, but as a convenience, calculates a checksum to fill in during creation. To fix the cyclic imports, I made use of typing.TYPE_CHECKING # managers.py import typing as t from django.apps import apps from django.db import models if t.TYPE_CHECKING: PublishedBundle = apps.get_model(app_label="the_hugh", model_name="PublishedBundle") class PublishedBundleManager(models.Manager): # Error 1 def create_publish(self, data: t.Dict, description: str) -> PublishedBundle: # Error 2 PublishedBundle = apps.get_model(app_label="my_app", model_name="PublishedBundle") json_data = json.dumps(data, sort_keys=True) md5_checksum = hashlib.md5(json_data.encode("utf-8")).hexdigest() return PublishedBundle.objects.create(data=data, md5_checksum=md5_checksum) However, I'm getting 2 errors. Missing type parameters for generic type "Manager" [type-arg]mypy(error) name 'PublishedBundle' is not defined I'm fairly new with typed python and never faced this issue before. … -

How can a unique timestamp be incremented on constraint violation in a Django model?
As part of using TimescaleDB, which requires a timestamp as the primary key (time in SensorReading), I need to handle the case when the same timestamp is used by different sensor values. One elegant solution might be to smear colliding timestamps (add a microsecond on collision). How can this problem be solved in a robust and performant manner for the following models? class Sensor(models.Model): name = models.CharField(max_length=50) class SensorReading(models.Model): time = models.DateTimeField(primary_key=True, default=datetime.now) sensor = models.ForeignKey(Sensor, on_delete=models.CASCADE) value = models.FloatField() P.S. This is a workaround as Django does not support composite primary keys. Otherwise it would be possible to set the sensor and timestamp as a composite primary key. -

Template is giving wrong path to media directory and Django can't find the images
I have 2 models and their relationship it's OneToMany. So, one "imovel" (portuguese word to property) has many pictures ("fotos" or "imagens" in portuguese). My web application structure is very simple and I configured at settings: settings.py MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' urls.py urlpatterns = [ path('', index, name='index'), path('sobre_nos/', sobre_nos, name='sobre_nos'), path('', include('imoveis.urls')), path('admin/', admin.site.urls), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) So every picture that is uploaded, goes directly to 'media' structure and the images for properties goes to 'media/imoveis/%Y/%m/%d'. I want to show all pictures associated to a property in a template using a basic bootstrap carousel: imovel.html <div id="carouselExampleControls" class="carousel slide" data-ride="carousel"> <div class="carousel-inner"> {% for foto in fotos_do_imovel %} {% if foto.imagem %} <div class="carousel-item activate"> <img class="d-block w-100" src="{{ foto.imagem }}"> </div> {% else %} <div class="carousel-item"> <img class="d-block w-100" src="{{ imovel.foto_principal }}"> </div> {% endif %} </div> {% endfor %} <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev"> <span class="carousel-control-prev-icon" aria-hidden="true"></span> <span class="sr-only">Anterior</span> </a> <a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next"> <span class="carousel-control-next-icon" aria-hidden="true"></span> <span class="sr-only">Proxima</span> </a> </div> The problem is, when I access the page to imovel.html, the pictures are not found: imoveis/2020/10/01/pexels-photo-1571463.jpeg imoveis/2020/10/01/pexels-photo-1643383.jpeg [01/Oct/2020 21:20:35] "GET /imovel/3 HTTP/1.1" 200 5952 Not Found: /imovel/imoveis/2020/10/01/pexels-photo-1643383.jpeg Not Found: /imovel/imoveis/2020/10/01/pexels-photo-1571463.jpeg [01/Oct/2020 … -

How to use an image generated in Javascript in a function inside my Django's view?
I'm making an application where my view renders a template with information, then inside my template with Javascript I create a canvas element, I have the data:URI in my Javascript code, but I want to save correctly that image in my MEDIA_ROOT (supposed in /media/report directory) on my server in a Django's way, as I do in another view with a form, but this is not a form! Is a success page where render the template with information and in the same view I have a function that I need that image, maybe my problem can be a little tricky but I will put a screenshot and my view to show what I want to do.

django rest framework serializer - doesn't return empty list field
I have a serializer for a model that contains JsonField. I want to always return specific fields, even when they are not found within the jsonField. When calling 'get' - it does return all fields in the serializer, but when calling 'update', it returns the instance with the updated fields and allow_null=True, so default=list field that wasn't update - would not return in the response. The question is how can I still return all serializer fields in response, including the default=list fields, even when they weren't updated and not exist? this is the serializer - class ObjectsListSerializer(serializers.Serializer): days = serializers.IntegerField(allow_null=True, source='objects_list.days') user_list = serializers.ListField(child=serializers.CharField(), default=list, allow_empty=True, required=False, source='objects_list.user_list') manager = serializers.CharField(allow_null=True, source='objects_list.manager') def update(instance, validated_data): if 'objects_list' in validated_data: for attr, value in validated_data['objects_list'].items(): instance.objects_list[attr] = value instance.save() return instance As mentioned, when sending 'get' request, even when 'objects_list' is empty, I would get days=None user_list=[] manager=None in the response But when user_list doesn't exist and I'm updating other field ('days' for example), 'user_list' will not exist in the response. Any idea how can I still return the empty list when it doesn't exist? -
Implementing reset password for different user app in django
PLease I have two two apps that handle two kinds of users in my project. The two kinds of user have different privileges on the site (I also have groups based on these two user account apps). The problem am having is that the default. from django.contrib.auth import views as auth_views has only one file structure in contrib/admin/templates/registration. I have this in urls.py for the diferent apps: path('reset_password/', auth_views.PasswordResetView.as_view(template_name="users/reset_password.html"), name="reset_password"), path('reset_password_sent/', auth_views.PasswordResetDoneView.as_view(template_name="users/password_reset_sent.html"), name="password_reset_done"), path('reset/<uidb64>/<token>/', auth_views.PasswordResetConfirmView.as_view(template_name="users/password_reset_form.html"), name="password_reset_confirm"), path('reset_password_complete/', auth_views.PasswordResetCompleteView.as_view(template_name="users/password_reset_done.html"), name="password_reset_complete"), For the second app, I have this in the urls.py path('reset_password/', auth_views.PasswordResetView.as_view(template_name="companyusers/reset_password.html"), name="reset_password"), path('reset_password_sent/', auth_views.PasswordResetDoneView.as_view(template_name="companyusers/password_reset_sent.html"), name="password_reset_done"), path('reset/<uidb64>/<token>/', auth_views.PasswordResetConfirmView.as_view(template_name="companyusers/password_reset_form.html"), name="password_reset_confirm"), path('reset_password_complete/', auth_views.PasswordResetCompleteView.as_view(template_name="companyusers/password_reset_done.html"), name="password_reset_complete"), but django does not seem to find the template paths unless I put the html files in the general templates folder for the project thus: path('reset_password/', auth_views.PasswordResetView.as_view(template_name="reset_password.html"), name="reset_password"), path('reset_password_sent/', auth_views.PasswordResetDoneView.as_view(template_name="password_reset_sent.html"), name="password_reset_done"), path('reset/<uidb64>/<token>/', auth_views.PasswordResetConfirmView.as_view(template_name="password_reset_form.html"), name="password_reset_confirm"), path('reset_password_complete/', auth_views.PasswordResetCompleteView.as_view(template_name="password_reset_done.html"), name="password_reset_complete"), So when a user resets to password, the final login page points to just the login page for one user. Meanwhile the two apps in the project has two different login pages. when I try to use url name-spacing for the reset password url paths, django is not able to find them since they are not in the root directly.

KeyError in graphql when reusing DRF serializer
So I am trying to implement graphql and reuse my serializer.py file but am getting "name 'request' is not defined". I can see what it's referencing on the serializer but no clue how to fix it. It seems to be hanging on the self.context["request"] I used to pop the password field from my put methods when using drf. any ideas as to how best to get around this. I am still learning and seem to be hitting a wall. Any help would be greatly appreciated.

cant import the file itself in pyinstaller
i am trying to use pyinstaller to pack my single file web application as follow, which can be run normally by tested, hoping to use it in another computer without python import os this = os.path.splitext(os.path.basename(__file__))[0] if __name__ == '__main__': import sys from daphne.cli import CommandLineInterface sys.exit(CommandLineInterface().run(["-p", "30003", this + ":application"])) else: import django from django.conf import settings from django.core.asgi import get_asgi_application from django.urls import re_path from django.http import JsonResponse DEBUG = True urlpatterns = [ re_path(r'^', lambda x: JsonResponse({'msg': 'success'})) ] SETTINGS = dict( DEBUG=DEBUG, ROOT_URLCONF=this ) settings.configure(**SETTINGS) django.setup() application = get_asgi_application() but when i run the packed file, it returns Error daphne/server.py:11: UserWarning: Something has already installed a non-asyncio Twisted reactor.

I know this might be a really obvious question, but I'm doing a Django project where I have Javascript in my static files.

How can i set permission on url
I am new on Django, I have implemented a valid form and now i want to set permission on url. When a form is submit then it redirects me to this url http://127.0.0.1:8000/success/. Without submitting a form i can manually type the name of the url "http://127.0.0.1:8000/success/" and it will take me to the same page. How can i set permission on "success" url, so that user can not manually view the page unless the form is valid and submitted. Do i need a decorator for this?
