Django Horizontal Scroll on Top of Changelist
I have the same problem as depicted here by mozman2: "In my Django changelist there are lots of columns that means there is a scrollbar at the bottom of the list. Is it possible to get a scrollbar to appear at the top so I don't need to scroll down" The solution from the given link seemed to help mozman2. However, I cannot reproduce it. Hence I tried copy-pasting the code from https://github.com/avianey/jqDoubleScroll#readme In particular, I copied this file from the repository to MyApp/static/admin/js/ jquery.doubleScroll.js The file looks like this: /* * @name DoubleScroll * @desc displays scroll bar on top and on the bottom of the div * @requires jQuery * * @author Pawel Suwala - http://suwala.eu/ * @author Antoine Vianey - http://www.astek.fr/ * @version 0.5 (11-11-2015) * * Dual licensed under the MIT and GPL licenses: * http://www.opensource.org/licenses/mit-license.php * http://www.gnu.org/licenses/gpl.html * * Usage: * https://github.com/avianey/jqDoubleScroll */ (function( $ ) { jQuery.fn.doubleScroll = function(userOptions) { // Default options var options = { contentElement: undefined, // Widest element, if not specified first child element will be used scrollCss: { 'overflow-x': 'auto', 'overflow-y': 'hidden', 'height': '20px' }, contentCss: { 'overflow-x': 'auto', 'overflow-y': 'hidden' }, onlyIfScroll: true, // top scrollbar is not … -
How to estabalish ManyToMany relationship on instantiation of object through generic CreateView?
So I have two models. Deck and Card. When the user creates card it should be tied to a deck, in a ManyToMany relationship. The card is created through the Generic Django create view, and I can't crack how I can assign the card to a deck, in this context. Any ideas on how I might solve this? My CreateView class CardCreateView(LoginRequiredMixin, CreateView): model = Card fields = ['question', 'answer'] def form_valid(self, form): form.instance.creator = self.request.user return super().form_valid(form) def get_success_url(self): return reverse('spaced_repitition-home') def assign_card(self, deck_id): #It's largely this part where I don't understand that it doesn't work card = self.get_object() deck = get_object_or_404(Deck, pk=deck_id) card.decks.add(deck) card.save() Template that sends user to form (passes on deck_id) {% for deck in decks reversed %} <a href="{% url 'card-create' deck_id=deck.id %}"> <p> Add Card </> {% endfor %} Form Template {% extends "spaced_repitition/base.html" %} {% load crispy_forms_tags %} {% block content %} <div class="content-section"> <form method="POST"> {% csrf_token %} <fieldset class=form-group> <legend class="borders-bottom mb-4"> Create Card </legend> {{ form|crispy }} <div class=form-group> <button class= "btn btn-outline-info" type="submit"> Create </button> </div> </fieldset> </form> {% endblock content %} Models class Deck(models.Model): title = models.CharField(max_length=100) date = models.DateTimeField(default=timezone.now) creator = models.ForeignKey(User, on_delete=models.CASCADE) description = models.TextField(max_length=200, blank=True) … -
RenderItems is not defined no-undef inside return
Hello Guys am new in reactjs and Iam trying to get response data object to be able to display on the webapp for the users to see instead of them inspecting the page and going to network/console to see the file upload error response of name= 'title' so I decided to use the function below to be able to give me the data response and I keep on getting this error 'renderItems is not defined' no-undef Heres the sample code: import React from "react"; import PropTypes from "prop-types"; import axios from 'axios' import { Card,} from "shards-react"; class Uploaddatastore extends React.Component { constructor(props) { super(props); this.state = { UploadNotification: [] } } componentDidMount(){ let notificationComponent = this; axios.get("http://127.0.0:8000/uploads/file_upload/") .then(function (response) { console.log(response); console.log(response.data); notificationComponent.setState({ UploadNotification: response.data.items }); }) .catch(function (error) { console.log(error); }); } render() { if (this.state.UploadNotification.length) { let renderItems = this.state.UploadNotification.map(function(item, i) { return <li key={i}>{item.title}</li> }); } return ( <div> <span className="text-danger"> {renderItems} </span> </div> ); } }; export default Uploaddatastore; -
Not able to serialize a model object in django signals
I have a Task model. After saving the task I want to send a FCM to a device. So I decided to use django signals. Here's the code for it: The model: class Task(models.Model): id = models.AutoField(primary_key=True) issuer = models.ForeignKey(EndUser, on_delete=models.CASCADE, related_name='history') assignee = models.ForeignKey(Mechanic, on_delete=models.CASCADE, related_name='history') vehicle = models.ForeignKey(Vehicle, on_delete=models.CASCADE, related_name='history') service = models.ForeignKey(Service, on_delete=models.CASCADE) status = models.CharField('Task Status', choices=TASK_STATUS, default=TASK_STATUS[0][0], max_length=64) payment_status = models.CharField('Payment Status', choices=PAYMENT_STATUS, default=PAYMENT_STATUS[0][0], max_length=64) def __str__(self): return "{}-{}-{}".format(self.service, self.issuer, self.assignee) post_save.connect(send_mechanic_notification, sender=Task) The signal function: def send_mechanic_notification(sender, instance, created, **kwargs): if created: instance.assignee.device.send_message( title='New Task Available!', body='Hey!! A new task is available for you', data={ "event": "new_task", "data": instance } ) Now, obviously this won't work because instance is a model object and needs to be serialized. So I tried using a serializer that I have defined. But this was causing circular dependency. I don't want to user model_to_dict because it doesn't serialize the nested fields, and serializing the nested fields is a requirement. How can I solve this problem? -
Django 2.2 how do i list objects with a many to many in a template?

CeleryD seems to ignore concurrency arguemtn
I've recently upgraded my Django project to Celery 4.4.6 and things aren't going well. My current number one problem is the concurrency of tasks. Because the tasks lock database tables and some are very memory intensive, there's no chance to run eight tasks at the same time. However, that is what celery is set on doing. Previously I was able to run just two tasks at the same time. The worker is daemonised and only one worker is live (one node). I set the concurrency to two. Here's my /etc/default/celeryd: # most people will only start one node: CELERYD_NODES="worker1" # but you can also start multiple and configure settings # for each in CELERYD_OPTS #CELERYD_NODES="worker1 worker2 worker3" # alternatively, you can specify the number of nodes to start: #CELERYD_NODES=3 # Absolute or relative path to the 'celery' command: CELERY_BIN="/home/ubuntu/dev/bin/python -m celery" #CELERY_BIN="/virtualenvs/def/bin/celery" # App instance to use # comment out this line if you don't use an app CELERY_APP="match2" # or fully qualified: #CELERY_APP="proj.tasks:app" # Where to chdir at start. export DJANGO_SETTINGS_MODULE="match2.settings" CELERYD_CHDIR="/home/ubuntu/dev/match2/match2" # Extra command-line arguments to the worker CELERYD_OPTS="--concurrency=2" # Configure node-specific settings by appending node name to arguments: #CELERYD_OPTS="--time-limit=300 -c 8 -c:worker2 4 -c:worker3 2 -Ofair:worker1" # … -

Django Form- Password Validation
I am new to Django just started learning it yesterday. I am trying to create a register form. I know there is inbuilt django register system. But i am trying to it myself. This is my Views.py- def register(request): if request.user.is_authenticated: return render(request, 'users.html', {}) else: if (request.method=='POST'): form=Register(request.POST) if form.is_valid(): form.save() return render(request,'home.html',{}) else: return render(request,'register.html', {}) Template- <form method="post"> {% csrf_token %} <input type="text" name="username" placeholder="Username" required><br> <input type="email" name="username" placeholder="Email" required><br> <input type="password" placeholder="Password" name="password" required><br> <input type="password" placeholder="Password" name="cpassword" required><br> <input type="radio" name="gender" value="male">Male <input type="radio" name="gender" value="female">Female<br> <input type="submit"> form.py class Register(forms.ModelForm): class Meta: model = Users fields = ["username", "email", "password","gender"] But since there is no confirm password field in form.py. It does not past form.is_valid() statement. I know this may be a stupid. But just can't find a way to do this. -
How to test which EMAIL credentials were used in tests
I am building an application that sends email through multiple email servers. To achieve this, I created my own settings that allow for multiple email server configurations. Now I am testing and I want to ensure the method is inserting the correct credentials. I looked at the django.core.mail and there does not appear to be anything there. Is there a way to test which credentials were used when testing email sending? -
Django channels, time a message in a websocket
I want to implement a WebSocket which execute a queryset every 120 seconds and returns a response in according to some logic (already exsits) class CarConsumer(JsonWebsocketConsumer): def connect(self): # Manually adding a user for now, later from the url route. self.user_name = '1' self.user_group_name = 'user_%s' % self.user_name self.group = [self.user_group_name, self.channel_name] # Join user group async_to_sync(self.channel_layer.group_add)( self.group[0], self.group[1] ) # TODO: Once working, add Auth # accept connection self.accept() def car(self): result = self.check_events() # Get updated car status self.channel_layer.send( self.farm_group_name, # send result to group {'type': 'check_events', 'message': result } ) def check_events(self): Car.objects.filter() # rest of logic cut dows due to length. So, this code connects when using: const ws = new WebSocket("ws://127.0.0.1:8000/ws/car_online/connect/"); a connection is established, but I can't seem to be able to send a proper message, and other then that, I want the check_events method (the logic) to run every 120 seconds, how can I implement this behavior? The result of the check events method is always a dictionary if it changes something. -

React put method not updating the user from Django
I have a Django as backend and updating the user from postman is working fine. But when I update it via React Frontend, it replies with a success message just as in Postman, but the data was not updated. This is the update function to update: const updateData = (e) => { e.preventDefault(); const csrftoken = getCookie("csrf"); const cookies = new Cookies(); const url = "http://localhost:8000/usercontrol/update"; setIsLoading(true); fetch(url, { method: "PUT", headers: { "Content-Type": "application/x-www-form-urlencoded", Authorization: "Token " + cookies.get("token"), "X-CSRFToken": csrftoken, }, body: JSON.stringify({ email: userinfo.email, username: userinfo.username, first_name: userinfo.first_name, last_name: userinfo.last_name, }), }).then((response) => console.log("THE RESPONSE: ", response.json())); setIsLoading(false); }; This is what it prints out in the console Since I am partially following CodingWithMitch for Django user creation with rest framework is similar to his. Furthermore, since there is no error outputting and is working fine in Postman, I have no idea what is wrong with it. -
