Django: How to unable unlogged user get data other users but enable him have his own data linked to his session
I'm working on simple django project. In this project every reuser has his own data collection as usual we do in our projects but I want to enable unlogged users to have his own data linked with particular session. Off course their data are deleted when session expired but this is the cost of not being registered. I want to block possibility for unlogged user to get data of registered users by typing direct url. All tutorials i have found are obout @login_required decorator but it works only for registered users and doesn't let unlogged users to have his own temporary data. Maybe somebady can help my , give my a hint or suggestion where i can find something useful to solve this problem. Thanks for help -

Call ajax of `django-restframework` api from template and the server checks who calls this api
I use google auth login in django project with django-oauth-toolkit What I want to do is Call ajax of django-restframework api from template and the server checks who calls this api. For example, I can get if user is login or not {% if user.is_authenticated %} in template. so, I can call the api with the user information like this. var url = "http://localhost/api/check?id={{user.email}}" $.ajax({ method:"get", url:url .... with id query server can understand who calls this request. However in this method,id is written barely, so you can make the fake request. So, I guess I should make some access token or some other key. Is there any general practice for this purpose??? -

Display all User profiles, in Django template, liked by the currently logged-in User (under ManytoMany field)
I built a portal, where members can see other users' profiles and can like them. I want to show a page where the currently logged-in users can see a list of profiles only of the members they liked. The Model has a filed 'liked', where those likes of each member profile are stored: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='default.jpg', upload_to='profile_pics') company = models.CharField(max_length=500, blank = True) city = models.CharField(max_length=100, blank = True) website = models.URLField(max_length=500, blank = True) liked = models.ManyToManyField(User, related_name='user_liked', blank=True) My views.py, and here I only show all members so on my template I can loop through each member in members... Including 'member.profile' details from the Profile model. @login_required def all_fav_members(request): users = User.objects.all context = {'members':users} return render(request, 'club/all_fav_members.html', context) I've tried many things, both under views.py and my HTML template, but I was not able to loop through all users associated with a specific Profile under the 'liked' field where that user is equal to request.user. I'm new to Django, hence trying multiple things. The outcome usually is I get the whole list of members, not the ones current user liked. One of the not working examples: {% if member.profile.liked.filter(id=request.user.id).exists()%} My template: … -
Django debug toolbar not showing view class name
I am using a django-debug-toolbar==3.4.0 with Django==4.0.5.

I am getting the selected boxes data via the datatable script but I need to send this data to views.py on submission. I have used AJAX but it seems that I have been doing something wrong. Could you please help. Javascript on html: $(document).ready(function() { var table1 = $('#pgnum').DataTable({ 'columnDefs': [ { 'targets': 0, 'checkboxes': { 'selectRow': true } } ], 'select': { 'style': 'multi' }, 'order': [[1, 'asc']] }); // Handle form submission event $('#eg').on('submit', function(e){ var arr = []; var form = this; var rows_selected = table1.column(0).checkboxes.selected(); // Iterate over all selected checkboxes $.each(rows_selected, function(index, rowId){ // Create a hidden element arr.push(rowId); }); $.ajax({ type: "POST", url: "{% url 'add_user_eng' %}", data: {arr: 'arr'}, }); }); }); urls.py url(r'^eng_edit_admin/eng_add_user', views.add_user_eng, name='add_user_eng'), views.py def add_user_eng(request): token = request.session['eng_id'] eng_id = str(token) user_list = User.objects.all() if request.method == 'POST': print("HELLO") print(request.POST.getlist('data[]')) return render(request, 'main/add_user_to_engagement.html',{'user_list':user_list}) form id="eg" I am getting an empty list even when I submit or reload the page. Any sort of help is appreciated. Thank you -
