CSS definitions in django-allauth account templates
I am trying out django-allauth and have come across a block while customizing the allauth account templates. I am presently working on the emails.html template but I am unable to find any definition for the css classes used inside the default templates. CSS classed such as ctrlHolder or primary_email. Please help me with figuring out where these are defined. I can use the bootstrap css but was hoping to keep the default ones if they are good enough. accounts/emails.html {% extends "account/base.html" %} {% load i18n %} {% block head_title %}{% trans "E-mail Addresses" %}{% endblock %} {% block content %} <h1>{% trans "E-mail Addresses" %}</h1> {% if user.emailaddress_set.all %} <p>{% trans 'The following e-mail addresses are associated with your account:' %}</p> <form action="{% url 'account_email' %}" method="post"> {% csrf_token %} <div class="form-group"> {% for emailaddress in user.emailaddress_set.all %} <div class="ctrlHolder"> <label for="email_radio_{{ forloop.counter }}" class="{% if emailaddress.primary %}primary_email{% endif %}"> <input id="email_radio_{{ forloop.counter }}" type="radio" name="email" {% if emailaddress.primary or user.emailaddress_set.count == 1 %}checked="checked"{% endif %} value="{{ emailaddress.email }}"/> {{ emailaddress.email }} {% if emailaddress.verified %} <span class="verified">{% trans "Verified" %}</span> {% else %} <span class="unverified">{% trans "Unverified" %}</span> {% endif %} {% if emailaddress.primary %}<span class="primary">{% trans "Primary" … -
Django Guardian - Check Permission during filtering
Im using Django Guardian to use Instance Permissions. It works well but I have a question about filtering. Lets say we have a models called FakeItem. Lets say we want to filter FakeItems list with only item with a specific permission. @staticmethod def purge_list(entity_list , userOrUsername, permission_name): requesting_user = userOrUsername if not isinstance(userOrUsername, User): requesting_user = User.objects.get(username = username) acl_listed = [] total_rows = 0 for entity in entity_list: if requesting_user.has_perm(entity, permission_name): acl_listed.append(entity) total_rows = total_rows + 1 return { "list" : acl_listed , "totals" : total_rows } This is an example of a method to purge list from item the user can access. Unfortunally this method is called AFTER I get the total list from database with a previous filter. I need to make a O(n) interation over the list to purge it. I need something to purge the list directly in the original filter to optimize the query. search_filter = Q() search_filter = search_filter & Q(name__icontains = "foo") search_filter = search_filter & Q(some_guardian_filter) already_purged_list = FakeItem.objects.filter(search_filter) Guardian's Documentation only explain how to use single method like has_perm etc... -

How can I use function in models class to add or modify field value before save it?
Hi I am creating one app in Django and created the UserTravelDetails model which will help to store user_id, start and end destination stations_id and route_string. In the route_string field, I want to perform some logic which I wrote in route_string1 function before store data in this field. Here is my code: class UserTravelDetails(models.Model): def __init__(self, route_string1): self.func = route_string1 usr = models.ForeignKey(Users, on_delete=models.CASCADE) start_station_id = models.ForeignKey(Station, on_delete=models.CASCADE, related_name='start_station') destination_station_id = models.ForeignKey(Station, on_delete=models.CASCADE, related_name='destination_station') route_string = models.CharField(max_length=50, default="ok") def __call__(self, *args, **kwargs): return self.func(self) class Meta: verbose_name_plural = "Users Travel History" @UserTravelDetails def route_string1(user): start_station = user.start_station_id destination_station = user.destination_station_id # A and C both on same color # A-->C if start_station.color == destination_station.color: user.route_string = f"{start_station.name}---> {destination_station.name}" else: # A---> D---> C color1_objects = [i.name for i in Station.objects.all().filter(color=start_station.color)] color2_objects = [i.name for i in Station.objects.all().filter(color=destination_station.color)] junction_station = [i for i, j in zip(color1_objects, color2_objects) if i == j] if junction_station: user.route_string = f"{start_station}--> {junction_station}--> {destination_station}" else: # remaining_color_list = pass # A---> B---> D---> C but I am getting error: TypeError: __init__() missing 1 required positional argument: 'route_string1' is there any way to use functions in models class for specific fields? -
Wrap some text in Django Admin field
I have this Django admin page: The second field, "Descrizione", contains a string (taken from a database) of max 500-chars length: I want that this text is entirely displayed in the page, while Django sets up a field as long as the string length, and so I have to sshift it with the right arrow in order to read it. So, how can I make an automatic text wrapping? Hope the question is clear. -
Python requests get content from streaminghttpresponse
I have a django API that stream a response using protobuff messages def retrieve(self, request, event_date=None, notification=None): ... return StreamingHttpResponse(self.generator(leaseEvents, 2000), content_type='application/protobuf') def generator(self, qs, BATCH_SIZE=2000): pages = Paginator(qs.order_by("event_date").values_list('reference', 'event_date', 'event_msg'), BATCH_SIZE) for i in pages.page_range: p = pages.get_page(i) for event in p: # filling protobuf object yield lease_event.SerializeToString() Using Postman to querry the api works well. My goal is to get the result with the python requests module, but i only get an empty response. with requests.get(url, stream=True) as r: print(r) print(r.headers.get('content-type')) print(r.headers) print(r.content) print(len(r.content)) print(r.elapsed.total_seconds()) for line in r.iter_lines(): print("hi") if line: # filter out keep-alive new lines print(line) Here is the result <Response [200]> application/protobuf {'Date': 'Tue, 14 Apr 2020 09:05:45 GMT', 'Server': 'WSGIServer/0.2 CPython/3.8.1', 'Content-Type': 'application/protobuf', 'Vary': 'Accept, Cookie', 'Allow': 'GET, HEAD, OPTIONS', 'X-Frame-Options': 'SAMEORIG IN', 'Content-Length': '0'} b'' 0 0.675784 I thinks Requests assume the content-length is 0, event if I'm using StreamingHttpResponse which dosen't provide content-length. Am I missing something ? Thanks in advance :) -

Django queryset using select_related and prefetch_related
models.py class Question(Model): pass class Topic(Model): question = models.Foreignkey(Question) class Syllabus(Model): topic = models.Foreignkey(Topic) #The Bridge Model class Test_Syllabus(Model): test = models.Foreignkey(Test) syllabus = models.Foreignkey(Syllabus) class Test (Model): pass I have a test object as follows: test = Test.objects.get(id=pk) Using the test object, I want to get the related queryset of questions. So, I tried the following code: questions = test.test_syllabus_set.all() #don't know how to go further from here I think it has something to do with select_related and prefetch_related. Please help me out with a perfect query for this use case. -

Serial file upload VS Parallel file upload
Scenario: There's a frontend (an iOS application) and a backend (a server). Frontend needs to upload a set of images ranging from 1 - 10 (Nos. may vary) with some image data, to the backend. Question: 1) Do I upload the images in parallel (One network request per image) or in serial (all images in a network request). Which method method would be better in terms of speed and other factors? 2) If serial upload is best suited, to my knowledge, multipart form-data is used. Considering the below details of the image, how to create the body to accommodate multiple records? { "picture" : "@/Users/userName/Desktop/picture.png", "model" : "the model name to which the image is linked", "record_id" : "the record, to which the image is linked" } I use Swift and Python (Django). For testing purposes I use postman and curl. Thank you -

Attach Multiple Instances of A Single Object Type To Multiple Parent Objects Types in Django
I have these models: class Organization(models.Model): name = models.CharField(verbose_name="Orgainzation Name", max_length=100, unique=True) ein = models.CharField(verbose_name="Entity Identification Number", max_length=10, unique=True) address = models.ForeignKey(Address, on_delete=models.SET_NULL) created = models.DateTimeField(auto_now_add=True) created_by = models.ForeignKey(settings.AUTH_USER_MODEL, models.SET_NULL) updated = models.DateTimeField(auto_now=True) updated_by = models.ForeignKey(settings.AUTH_USER_MODEL, models.SET_NULL) class User(AbstractUser): address = models.ForeignKey(Address, models.SET_NULL) birth_date = models.DateField() phone = models.CharField(max_length=15)``` I want to be able to attach multiple files to each object type Organization and User. I created these models to do so: class OrgFile(models.Model): file = models.FileField() parent = models.ForeignKey(Organization, models.SET_NULL) class UserFile(models.Model): file = models.FileField() parent = models.ForeignKey(settings.AUTH_USER_MODEL, models.SET_NULL) It seems like there should be a way to use one File model and attach it to different types of objects. Is this possible or do I need to make a class for each parent type?
