How to create multiple text contains filter in Django filters?
I am working with a django site and using django-filters to make filters. so i created a model as follows: class Bids(models.Model): Services=models.CharField(max_length=300) and that field contains many random words like 'services,manpower,security,machines,chemical,.. etc' so i created a django-filter as follows: class BidsFilter(django_filters.FilterSet): Services=CharFilter(field_name='Services',lookup_expr='icontains') class Meta: model=Bids fields="Services" and on my view i am using this filter as follows: def index(request): bidsData= Bids.objects.all() myFilter=BidsFilter(request.GET,queryset=bidsData) bidsData=myFilter.qs context = { 'Bids': bidsData, 'myFilter':myFilter } return render(request,"base.html",context) and on my template i am showing this filter as form: <form method="GET" >{{ myFilter.form }}<button class="btn-btn- primary"type="submit">Apply Filter</button></form> right now what happening is when i type a word eg. manpower the records having this word are printed. and if i type another word 'services' than those records are getting printed. What i want is to create multiple keyword filter for example if someone type 'manpower' than those records which have 'manpower 'are printed and also if someone types 'services' than those records which have 'services' word also printed and so on. its like a Tag filter you know like twitter and instagram can anyone show a good way of doing it. thanks in advance <3 -
Recommended file manager for Django Jazzmin admin
I am using Jazzmin theme in my Django admin panel and I am wondering if there is any recommended library to handle media files? I've installed django-filer but I see no option to integrate it with my summernote/tinyMCE or CKEditor. It doesn't matter for me which one I will be using. The most important is to have an option to insert uploaded images from body field in my model (it is textfield). I want to integrate it only in admin panel. -
what is equivalent to url(r'name/$') using path? I don't want users to access a django path
When considering url() in django, '$' allows you to block the url path. What is equivalent when considering 'path'? To be more precise I have the following path('',views.home,name='home'), path('json', json, name="json"), my home page calls the json file to plot a chart, however if user types in the url '.../json' they can access the json data file. I want users to not have access to the path /json but I still want my home page to access this json path. Thanks -
How to create custom button in Django admin, which create many object?
I have a model Student: from django.db import models from django.contrib import admin class Student(models.Model): name = models.CharField(max_length=30, default='') lastname = models.CharField(max_length=30, default='') grade= models.CharField(max_length=8, default='') class StudentAdmin(admin.ModelAdmin): list_display= ('name','lastname','grade') from django.contrib import admin from .models import * admin.site.register(Student, StudentAdmin) Imagine, that I have an additional model Person ( with name and surname fields). My situation is just an example. I want to create a button in the Django admin (it's very important to implement this in Django admin page), that creates many Student objects at once (name and lastname we take from Person, with empty grade field, which we can fill in the future). -
Async Stripe Function call
I am new to Django and I have been working on a Stripe based application and I found out that my class based views are quiet slow and I need to make them run as fast as possible. I discovered that in Django there is Asynchronous Support available but I am unable to figure how can I use it in class based views everywhere I find there are functional based example just. class BillSerializer(ReturnNoneSerializer, serializers.ModelSerializer): interval = serializers.CharField(read_only=True, required=False) amount = serializers.IntegerField(read_only=True, required=False) date = serializers.DateTimeField(read_only=True, required=False) is_active = serializers.BooleanField(read_only=True, required=False) subscription_expiry = serializers.BooleanField(read_only=True, required=False) active_jobs = serializers.IntegerField(read_only=True, required=False) class Meta: model = Billing fields = "__all__" def to_representation(self, validated_data): stripe.api_key = settings.STRIPE_API_KEY stripe_sub = stripe.Subscription.retrieve( self.context["request"].billing.stripe_subscription_id ) stripe_object = stripe_sub.get("items") quantity = stripe_object.get("data")[0].get("quantity") amount = ( stripe_object.get("data")[0].get("price").get("unit_amount") // 100 * quantity ) interval = stripe_object.get("data")[0].get("plan").get("interval") date = datetime.fromtimestamp(stripe_sub.current_period_end).strftime( "%Y-%m-%d %H:%M:%S" ) if validated_data.subscription_end < make_aware(datetime.now()): is_active = False else: is_active = True if validated_data.subscription_end <= make_aware(datetime.now()): subscription_expiry = True else: subscription_expiry = False return { "date": date, "interval": interval, "amount": amount, "quantity": quantity, "is_active": is_active, "subscription_expiry": subscription_expiry, } -
A better way to orgainize django-channels one to one private chat models?
I want to model the database table of a django channels private chat in the most effective way possible so that retrieving the messages would not take a lot of time. For that I have create a one to one room since every two users should have their unique room. And I created a separate message table with a foreign key relation with the (oneToOneRoom) table.But what bothers me is that since the sender and the receiver of the message can only be one of the two users of the room I do not want set (sender and receiver) as foreign Key to the users table. Can I have a better implementation of that. Or is their any other way of modeling those tables. Any help would be highly appreciated. Here is the models.py file. class singleOneToOneRoom(models.Model): first_user = models.ForeignKey( User, on_delete=models.SET_NULL, related_name="first_user", blank=True, null=True) second_user = models.ForeignKey( User, on_delete=models.SET_NULL, related_name="second_user", blank=True, null=True) room_name = models.CharField(max_length=200, blank=True, unique=True) def __str__(self): return f"{self.first_user}-{self.second_user}-room" class Meta: unique_together = ["first_user", "second_user"] class messages(models.Model): room = models.ForeignKey( singleOneToOneRoom, on_delete=models.CASCADE, related_name="messages") message_body = models.TextField() sender = models.ForeignKey( User, on_delete=models.CASCADE, related_name="msg_sender") receiver = models.ForeignKey( User, on_delete=models.CASCADE, related_name="msg_receiver") date_sent = models.DateTimeField(auto_now_add=True) def __str__(self): return f"{self.sender}_to_{self.receiver}" -

Why does Environ not set the variable in a Django project root other than the main?
So I have a .env file in my Django project root containing several variables. When I use them within the same project root (e.g. in settings.py) it works, but once I try to access a variable within another root/module it fails: # other root than .env import environ # Initialise environment variables env = environ.Env() environ.Env.read_env() # Get the iCloud application password via env mail_password = env('MAIL_PW') # --> returns django.core.exceptions.ImproperlyConfigured: Set the MAIL_PW environment variable This however works: # same root as .env import os import environ # Initialise environment variables env = environ.Env() environ.Env.read_env() # Build paths inside the project like this: BASE_DIR / 'subdir'.

I want to be able to check multiple users, and only choose a single option per user AND send all selected users in a list in template/html
So, I couldn't get a simple title, sorry for that. Basically, I want to send a message to X users. For this I need to select the users that I want to send this message to, and their type, if they are normal, CC or CCI. Every single type of option has a single name, meaning that in the end I get a list of normal recipients, of CC recipients and CCI recipients. All of this using check-boxes, needing me to create a javascript event to recreate a radio-type of behavior for the options of a single user. I was wondering if there was a better option than this, by using radios? Here is how it's looking: CCI aren't implanted yet since I started to ask myself this question when I was asked to make them... Here is the code for one user, with the onclick event being the function that recreate radio behavior... <label class="dropdown-item text-wrap labelname" style="overflow-wrap: break-word; padding-left: 5px; padding-right: 0px;"> <input class="green form-check-input me-1 checkboxes-recipients recipientsmessage " id="green2" onclick="syncUnCheck(green2, gray2)" type="checkbox" value="invite" name="recipients[]"> <input class="gray form-check-input me-1 checkboxes-recipients recipientsmessage" id="gray2" onclick="syncUnCheck(gray2, green2)" type="checkbox" value="invite" name="recipientsCC[]"> invité </label> The problem of this function is that It doesn't … -

Django ORM - add rows to the result until the SUM('column') reaches to a given number
I have a model created using Django ORM - class Orders: units = models.IntegerField(null=False, blank=False) sell_price_per_unit = models.FloatField(null=True, blank=True) created_by = models.ForeignKey(User, on_delete=models.PROTECT, null=False, blank=False) order_status = models.ForeignKey(OrderStatus, on_delete=models.PROTECT, null=False, blank=False) property = models.ForeignKey(Property, on_delete=models.PROTECT, null=False, blank=False) order_type = models.ForeignKey(Property, on_delete=models.PROTECT, null=False, blank=False) ... ...

Strategy to apply a common filter to all my graphene queries in a django project
When a user is asked to be removed from the system, I'll delete all his personal info like name and address from the auth_user table, but I'll keep all his system actions for internal analytics purposes. These analytics however, should not show up in our frontend web. For example, there's a table 'training' and one of the queries related to that is to see how many users are currently enrolled in a training. If an user has been removed he should not show up in there. Unfortunately I did the mistake of not creating a custom user model in the beginning of my Django project and it seems quite a hassle to do that now. Instead what I'm doing is to have a related model that links to the default User model. I created the RemovedUser model that simply flags that a user has been deleted. I know there is the 'is_active' field in the default model, but I don't want to use that one as I want to keep a distinction of actual completely removed users and inactive ones. Here is the model class RemovedUser(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) date_removed = models.DateTimeField(editable=False, default=timezone.now, help_text='Date the user was removed') Nothing … -

My MetaData model is class MetaData(models.Model): # Info id = models.IntegerField(primary_key=True) tag = models.CharField(max_length=500) # User Info username = models.CharField(max_length=400) followers = models.IntegerField() verified = models.BooleanField() profile = models.URLField() # Video Info upload_date = models.DateField() upload_time = models.TimeField() views = models.IntegerField() duration = models.CharField(max_length=50) comments = models.IntegerField() likes = models.IntegerField() dimension = models.CharField(max_length=50) framerate = models.CharField( max_length=100, blank=True, default='Not Found') # Post link = models.URLField() codecs = models.CharField(max_length=200, blank=True, default='Not Found') caption = models.CharField(max_length=100, blank=True, default='Not Set') status = models.CharField(max_length=20, choices=( ('Pending', 'Pending'), ('Acquired', 'Acquired'), ('Rejected', 'Rejected')), default='Pending') I am using Django rest framework pagination and getting my filters fields in parameters def fetchVideosContentwithFilter(request, filters, directory=None): paginator = PageNumberPagination() paginator.page_size = 12 # Parameters flts = ['upload_date'] if filters: flts = json.loads(filters) if 'upload_date' in flts: flts.append('upload_time') if directory and directory != 'all': objs = MetaData.objects.filter(tag=directory) else: objs = MetaData.objects.all() pages = paginator.paginate_queryset(objs.order_by(*flts), request) query = s.MetaDataSerializer(pages, many=True) return paginator.get_paginated_response(query.data) I also try or replace *paginator.paginate_queryset(objs.order_by(flts), request) with paginator.paginate_queryset(objs.order_by('-id'), request) but in vain data is not ordering correctly
