TypeError: context must be a dict rather than JsonResponse
I am trying to use ajax in class based Listview for pagination but it's not working.I saw many tutorial of ajax pagination but all of them is with function based views. #views.py class HomePage(ListView): model = Video template_name = 'index.html' def get_context_data(self, **kwargs): context = super(HomePage, self).get_context_data(**kwargs) videos = Video.objects.filter(category='sub') paginator = Paginator(videos, 5) page = self.request.GET.get('page2') try: videos = paginator.page(page) except PageNotAnInteger: videos = paginator.page(1) except EmptyPage: videos = paginator.page(paginator.num_pages) context['videos'] = videos if self.request.is_ajax(): html = render_to_string('video/index2.html', context, request=self.request) return JsonResponse({'form' : html }) else: return context The error I getting using this views is:- TypeError: context must be a dict rather than JsonResponse. If you have any different ways to achieve this ajax pagination .Please mention that.Thank you in advance. -

Python Django, Pandas: ForeignKey, his attributes and calculation
Good day, is there any solution to access the attributes of a ForeignKey inside my models.py and also to calculate inside a dataframe? class Object(models.Model): name = models.Charfield(max_length=100, null=False, blank=False) price = models.Integerfield(default=0) class Amounts(models.Model): object = models.ForeignKey(Object, on_delete=models.CASCADE) amount = models.Integerfield(default=0) Let's say the existing objects are looking something like this: id | name | price 1 | name_a | 2 2 | name_b | 4 3 | name_c | 8 Now I got a dataframe that looks something like this: id | object | amount 1 | name_a | 12 2 | name_b | 7 3 | name_c | 19 Is it possible to get the other attributes of the (via foreignkey) connected data and also to calculate inside the dataframe(in this case: price x amount)? Possible result: id | object | amount | price | calc 1 | name_a | 12 | 2 | 24 2 | name_b | 7 | 4 | 28 3 | name_c | 19 | 8 | 152 Thanks for all your help! -

How to split a string in django QuerySet object
In the view.py I am trying split an attribute value which is a long string. In a normal query: someposts = Posts.object.all()[3:5] should return: <QuerySet [object<first post>, object<second post>]> So then I query posts as follows as I need to split an attribute value (after this change I get the error): someposts = Posts.object.all().values('id', 'title', 'tags')[3:5] so it returns something like: <QuerySet [{'id': 2, 'title': 'first post', 'tags': ' X1, X2, X3,.., X10'}, {'id': 4, 'title': 'second post', 'tags': ' S1, S2, S3,.., S8'}] But I expect to receive tags as a list of stings, so what I did: splited_tags = [v['tags'].split(',') for v in someposts] for n, i in enumerate(someposts): someposts[n]['tags'] = splited_tags[n] and as the result <QuerySet [{'id': 2, 'title': 'first post', 'tags': [' X1', 'X2', 'X3',.., X10']}, {'id': 4, 'title': 'second post', 'tags': [' S1', 'S2', 'S3,.., 'S8']}] since I am passing someposts to my template: context = { 'someposts':someposts, } return render(request, 'app/home.html', context) and in home.html: {%for post in someposts %} <a class="avator" href="{% url 'user-post' post.author.username %}"></a> { % endfor %} I recieve this error: Reverse for 'user-post' with arguments '('',)' not found I think the problem is post.author.username since post is a string, … -

Django timesince function is wrong
I want to create a function that returns the list of last points per vehicle that have sent navigation data in the last 48 hours. I create a view it works and it displays name correctly but I want to show that How long has it been since the data was sent. I use timesince but it shows wrong. It adds 13 hours and prints same hours for all data.

Django: Pagination wont centre on page 1
I have added in a template pagination I found and it works fine but wont centre on page 1 even with "text-centre" and "justify-content-center" as recommended by other answers. It looks fine on page 2 and 3... as can be seen below {% block pagination %} {% if is_paginated %} <div class="text-center"> <ul class="pagination justify-content-center"> {% if page_obj.has_previous %} <li><a href="?page={{ page_obj.previous_page_number }}">&laquo;</a></li> {% else %} <li class="disabled"><span>&laquo;</span></li> {% endif %} {% for i in paginator.page_range %} {% if page_obj.number == i %} <li class="active"><span>{{ i }} <span class="sr-only">(current)</span></span></li> {% else %} <li><a href="?page={{ i }}">{{ i }}</a></li> {% endif %} {% endfor %} {% if page_obj.has_next %} <li><a href="?page={{ page_obj.next_page_number }}">&raquo;</a></li> {% else %} <li class="disabled"><span>&raquo;</span></li> {% endif %} </ul> </div> {% endif %} {% endblock %} This is the code i used and this is what it looks like on page 1 and its pulling to the right. I currently don't have any CSS code for the pagination, though I have tried different options with no luck.

I'm relatively new with Unix like systems and I'm trying to configure a Django application with nginx as web server using the uwsgi protocol. I'm using Ubuntu 20.4 LTS I followed this guide: https://www.digitalocean.com/community/tutorials/how-to-serve-django-applications-with-uwsgi-and-nginx-on-ubuntu-16-04 But when I start the uwsgi process it gives me this error: Aug 31 09:23:07 fucur-vm systemd[2255]: uwsgi.service: Failed to execute command: Permission denied Aug 31 09:23:07 fucur-vm systemd[2255]: uwsgi.service: Failed at step EXEC spawning /usr/local/bin/uwsgi: Permission denied Aug 31 09:23:07 fucur-vm systemd[1]: uwsgi.service: Main process exited, code=exited, status=203/EXEC Aug 31 09:23:07 fucur-vm systemd[1]: uwsgi.service: Failed with result 'exit-code'.

Hybrid Django Application - REST API Authentication
I am new to Django and have built a basic application (Django 3.1) which uses session authentication and a simple login page (username + password) to login a django user. It works fine. I would like to use javascript (vue.js) on pages accessible to the logged in user to call Django REST APIs, hosted on the same Django application. Despite lots of googling, no one seems to give a clear authentication example of a hybrid Django app, augmented with APIs. I have used lots of APIs before so am familiar with the authentication options. My issue is how to get credentials to the javascript loaded by django templates in a secure manner. IDEALLY I would like: User logs in with username/password django redirects to PAGE B, AUTOMAGICALLY SOMEHOW inserting user's token into a cookie/sessionStorage A javascript function on PAGE B gets credentials from cookie/sessionStorage and calls API (using all the various options supported by django-rest-framework) My Questions: Question 1 ==> in my do_login view function (below), after successful authentication with Djangos inbuilt login method, do I need to create a cookie in HttpResponse (e.g. token=XXXXXXX), so javascript can access it? Is this secure? def do_login(request): .... login(request, user) ... #create … -
Percent encoding in url
Suppose I have the code: params = {'a': '('} url = 'example.com/some-url?' + urlencode( {k: encode_param(v) for k, v in params.items()}).replace('&', '&amp;')' This gives example.com/some-url?a=%28 But when I access this url, it is not decoded to (. It remains %28. What is the function to properly encode query params? -
