Django Bootstrap Datepicker Plus loads with no default date or placeholder
I'm using Django with Date-Picker-Plus. Everything works correctly, except the date picker displays/has no value until you click the box. I have dug through all the documentation and can't find any references elsewhere of someone having this problem. I'm not familiar with js much so this is a bit foreign to me. Heres the documentation I've gone thru: https://django-bootstrap-datepicker-plus.readthedocs.io/en/latest/Usage.html http://eonasdan.github.io/bootstrap-datetimepicker/Options/#defaultdate class Meta: model = Jobs_DB fields = ['date_scheduled'] widgets = { 'date_scheduled': DatePickerInput( options={ "format": "MM-DD-YYYY", # moment date-time format "showClose": True, "showClear": True, "showTodayButton": True, 'defaultDate': True, }, ), } -
Notifications unclickable once "read": error "notification_id is not defined"
I am using JQuery/JS with Django Channels WebSockets to configure real-time notifications for chat messages. When a user has any Notification objects with nofication_read=False, they are rendered out in the navbar with the code below. {{ notification|length }} displays the number of Notification objects with nofication_read=False. navbar.html <li id="notification_li" class="nav-item"> <a class="nav-link" href="#" id="notificationLink"> <span id="notification_id{{notification_id}}">{{ notification|length }}</span> <div id="notificationContainer"> <div id="notificationTitle">Notifications</div> <div id="notificationsBody" class="notifications"> {% for notifications in notification|slice:"0:10" %} <span id="notification-{{notification.id}}"> {{ notifications.notification_chat.message }} via {{ notifications.notification_chat.user }} at {{ notifications.notification_chat.timestamp }} </span> {% endfor %} I know this isn't realtime at the moment. But the problem is that when the user refreshes the page and clicks on the red icon span id=notification_id to display their list of unread notifications, the data is sent through the websocket (JSON.stringify) as "type": "notification_read" which calls the if message_type == "notification_read": command in consumers.y which marks them as nofication_read=True in the database. When the user refreshes the page, the red icon is no longer there and when they try to click on the background link, it's unclickable with the error in the browser console Uncaught ReferenceError: notification_id is not defined As soon as they get another notification and the page is … -

raise MultiValueDictKeyError(key) with POST VXML
I get the following error raise MultiValueDictKeyError(key) : django.utils.datastructures.MultiValueDictKeyError: 'redirect' when I try to save the value the user types in.

Convert GET parameters to POST data on a Request object in Django REST Framework
I am in the process of rewriting the backend of an internal website from PHP to Django (using REST framework). Both versions (PHP and Django) need to be deployed concurrently for a while, and we have a set of software tools that interact with the legacy website through a simple AJAX API. All requests are done with the GET method. My approach so far to make requests work on both sites was to make a simple adapter app, routed to 'http://<site-name>/ajax.php' to simulate the call to the Ajax controller. Said app contains one simple function based view which retrieves data from the incoming request to determine which corresponding Django view to call on the incoming request (basically what the Ajax controller does on the PHP version). It does work, but I encountered a problem. One of my API actions was a simple entry creation in a DB table. So I defined my DRF viewset using some generic mixins: class MyViewSet(MyGenericViewSet, CreateModelMixin): # ... This adds a create action routed to POST requests on the page. Exactly what I need. Except my incoming requests are using GET method... I could write my own create action and make it accept GET requests, … -
iterate users in friends list over same modal and access database content
I am making a chat box for my website. As per current implementation,i i am iterating over the current friends list and and anchor tag triggers a modal for that particular user. The modal is common for all users as it only changes the data inside. Now, i have used jquery to fetch the message history ( from model object ) and display is modal body. I can click on different users and view the messages in their respective models correctly. However, when i try to submit the form to send another message it gets added to the message box of first user. This is happening for all users in the friend list. How can i trigger the form to post in the model of the correct user. Template {% for friend in friends_list %} <a href="" data-toggle="modal" data-target="#chatbox" data-whatever="{{friend.to_user}}"><li style="padding:10px">{{friend.to_user.usercreation.fname}} {{friend.to_user.usercreation.lname}} <i style ="color:green;font-size:0.65rem;text-align:justify;float:right;margin-top:8.5px;" class="fa fa-circle" aria-hidden="true"></i></li></a> <form action="{% url 'usercreation:addmessage' friend.to_user.usercreation.pk %}" method="post"> {% csrf_token %} <div class="modal fade" id="chatbox" tabindex="-1" role="dialog"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header text-center"> <h6 class="modal-title w-100">BlogChat</h6> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <pre><div class="modal-body"></div></pre> <div class="modal-footer"> <input style="width:330px;height:40px" type="text" name="addmessage" value="" placeholder="Type.."> <button style="float:right;" type="submit" class="btn btn-primary">Send message</button> … -

How can i avoid a user from registering an already used email in django?
I was testing my registration view and i noticed that if i try to register using an alreaxy existing Username, i'll get an error; if i try to register using an already existing email, the app will let me do so. Obviously, i don't want someone to register multiple accounts with the same email on my site. I'm fairly new to Django, and since i noticed that the form checked if an username already exists, i thought it would do the same with the email field. I don't really know how to go from that, should i work on my view or on the form? And how can i make it loop through my DB and find if an e-mail had already been registered? I thought email = form.cleaned_data.get('email') would do the trick, but it didn't. Any help is appreciated. Here is my view: def register(request): if request.method == "POST": form = NewUserForm(request.POST) if form.is_valid(): user = form.save() username = form.cleaned_data.get('username') email = form.cleaned_data.get('email') messages.success(request, f"New Account Created: {username}") login(request, user) messages.info(request, f"You are now logged in as {username}") return redirect("main:homepage") else: for msg in form.error_messages: messages.error(request, f"{msg}: {form.error_messages[msg]}") form = NewUserForm return render(request, "main/register.html", context={"form":form}) And here is the … -

How to build a real time iot sever using django rest api and websockets?
I'm building a real time iot server using django and I'm fairly new to django. I have used django REST api so far to get data using HTTP requests, by using JSON. Now I want to further expand my project with the use of django websockets. How can I use websockets with REST api to capture real time data from iot?

How to read value from a html image back to django view function?
I generate lots of images in html from local folders. I want to add links to all of these images (And triggered by a view function create_pc) and I want to send the image path to my view function. This is a part of my html file {% load static %} <h1>Color images:</h1> <ul> {% for img_path in Color %} <li><a href="/create_pc/"><img src="{% static img_path %}" width="100" height="100"></a></li> {% endfor %} </ul> In urls.py I have set the address to the function: path(r'create_pc/',views.create_pc) My function in view.py: def create_pc(request): return HttpResponse(str(img_path)) So I want to get the src="{% static img_path %}" in the create_pc function, which means the function knows which image is clicked. I don't know how to handle this. Please help me!
