Prefilter queries in django for a session
Currently I have an unique UUID tied to all models, including a one to one relation with the user model. For filtering data based on this UUID, I save the UUID as a session variable for the logged in user and then in the views, data = Model.objects.filter(unique_num=request.session.get('unique_num')) Is it possible to prefilter these queries. For example, if the user logs in, I should just be able to data = Model.objects.filter() and it should show only related data. -
How can I create a timeline with equal spacing between elements whilst maintaining full width of container?
Issue Description I have created a timeline within a kanban item. The timeline design is exactly what I want but I have an issue with spacing between the timeline elements. I require the timeline to cover the full width of the container with first and last positioned at the very start and end of container but with equal distances between each element. So instead of : O---O--O--O---O and more like: O--O--O--O--O But still maintain full width of the container. JSFiddle: https://jsfiddle.net/cn9m0wfz/5/ CSS .kanban-booking-item .mini-timeline-item { padding:0; display: flex; position: relative; } .kanban-booking-item .mini-timeline-item .item-container { background-color:rgb(209, 209, 209); height:15px; width: 15px; border-radius:10px; display: flex; justify-content: center; } .kanban-booking-item .mini-timeline-item .item { background-color:rgb(255, 255, 255); height:9px; width: 9px; border-radius:5px; margin:3px; } .kanban-booking-item .mini-timeline-item .pipe { background-color: #d1d1d1; height:3px; width: 100%; border-radius:5px; margin:3px; position:absolute; top:3px; } .kanban-booking-item .mini-timeline-item .pipe.pipe-left { left: -16px; } .kanban-booking-item .mini-timeline-item .pipe.pipe-right { right: -16px; } .kanban-booking-item .mini-timeline-item .pipe.pipe-centre-right { right: -9px; width: 50%; } .kanban-booking-item .mini-timeline-item .pipe.pipe-centre-left { left: -9px; width: 50%; } HTML <div class="kanban-booking-item" style="padding: 0px 40px 8px 10px"> <div class="content row" style="padding: 0 15px;"> <div class="mini-timeline-item col" style="justify-content:flex-start;"> <div class="item-container"> <div class="item"> </div> </div> <div class="pipe pipe-right"> </div> </div> <div class="mini-timeline-item col" style="justify-content:center;"> <div … -
Django Form Media creating Exception Value: Missing staticfiles manifest entry for 'lead_management/admin/extra.css'
I have the following within a Form I am using class Media: css = { 'all' : ('lead_management/admin/extra.css',) } I have recently upgraded from Py3.6, Django 2.1.10 to Py3.8, Django 3.1.7.

sending a javascript symbol through django json objects does not show
In Django (2.2) I am trying to send a json response like this: return JsonResponse(data, safe=False) In the data object there is this value "unit": "\u33A5" (cubic meters) when I am trying to print this value on my html page using javascript, I get this exact literal instead of the cubic meters symbol. I cannot paste javascript code because this symbol is supposed to be displayed as a y-axis label to an echarts graph, but this what I do: yAxis: { type: 'value', name: data.unit, nameLocation: 'middle', }, If I hardcode this "\u33A5" instead of data.unit in the options the cubic meters symbol appears. my question is how am I supposed to serialize or print correctly javascript symbol codes using the django JSON's response? -

Ajax is not sending multiselect data to Django views
I am quite new to Django so bare with me. I have a multiselct list in my webpage and I need to send the selected items to my views in order to make use of them. To do so, I used ajax but when it doesn't seem to work for some reason. This is the script: $("#var_button").click(function(e) { var deleted = []; $.each($("#my-select option:selected"), function(){ deleted.push($(this).val()); }); alert("You have deleted - " + deleted); e.preventDefault(); $.ajax({ type: "post", url: "/description/upload-csv/" , data: { 'deleted' : deleted } }); // End ajax method }); I checked with alert if maybe the variable deleted is empty but it return the selected values so the problem is in my ajax query. This is the part where I retrieve the data in my views.py if request.method == 'POST': del_var = request.POST.getlist("deleted[]") my_class.del_var = del_var I changed the data type to text but it doesn't do anything -

Type Error with Django Rest Framework SimpleJWT
I have set up django restframework with jwt, following some instructions that was working previously, however now whenever I go to try and obtain a token using the path I defined in my 'accounts' app, it works until I enter in credentials and make a POST request. Django throws me an error saying "TypeError at /accounts/api/token/ Expected a string value". This hardly makes sense to me because I am simple entering my password which is a string into the password field. If I enter in wrong credentials, it gives back a correct response saying there isn't such a user. which means it is set up correctly? please help I have been stuck for so long. This is what is returned with CORRECT credentials. This is what is returned with INCORRECT credentials -
Invalid HTTP_HOST header: The domain name provided is not valid according to RFC 1034/1035
Our Django server is often having this error: Invalid HTTP_HOST header: u'/home/appname/run/gunicorn.sock:'. The domain name provided is not valid according to RFC 1034/1035. I think this happens when the host is a real IP rather than a domain name. If you're thinking why such a host is making it to the Django app, it's because we're actually actually any host: ALLOWED_HOSTS = ['.appname.org', '*'] And we want to keep it this way because we're allowing clients to point their own domains to our proxy. We have a DomainNameMiddleware which checks the host name against our database and if not found, the request is rejected. However, it seems the "Invalid HTTP_HOST header" error happens before our domain name middleware runs, so the error is raised when our middleware would've handled it silently. How can I have this error fail silently?
