Django is not redirecting to profile page after login. What is wrong with my code?
This is my views.py def LoginPage(request): username = password = '' next = "" if request.GET: next = request.GET['next'] if request.method == 'POST': username = request.POST.get('username') password = request.POST.get('password') user = authenticate(request, username = username, password = password) if user is not None: login(request, user) if next == "": return HttpResponseRedirect('/Profile/') else: return HttpResponseRedirect(next) context = {} return render(request, 'login.html', context) This is my template: {% if next %} <form class="" action='/Profile/' method="post"> {%else%} <form class="" action="/Login/" method="post"> {% endif %} {% csrf_token %} <p class="login-field-title"><strong>Username*</strong></p> <input type="text" class="form-control col-lg-10 log-inp-field" placeholder="Enter Username" required> <p class="login-field-title"><strong>Password*</strong></p> <input type="password" class="form-control col-lg-10 log-inp-field" placeholder="Enter Password" required> {% for message in messages %} <p id="messages">{{message}}</p> {% endfor %} <button type="submit" class="btn btn-dark btn-lg col-lg-10 log-btn">Log In</button> </form> I don't understand what I'm doing wrong. Some help would be very appreciated. Even after logging in with a registered user it is not redirecting me to the desired page and when i change the action, even with the un registered user it redirects me to the next page. -

Retrieving Django model value based on another model
I was following a youtube's django database model queries but try doing it with different context to see if I understand the model concept and not just blindly following (and it turns out i do not understand it at all). I was trying to retrieve the "views" values in the model based on the tag name. I manage to pull the individual item but i do not know how to retrieve the view count based on the tag name.

How can I use a global/module level ThreadPoolExecutor in my python django server?
So this is the code setup I want. I'm using python2. I'm looking for do's and don'ts here. And to know if I am doing it right. Also another solution. I am trying this out, since my pods crash very quickly when doing load tests at around 100 rps. and with profiling I was seeing that each request was creating too many threads. The one problem I still have with this setup is that it does close idle threads after some timeout, while keeping only a handful of threads when the app is idle. pool = ThreadPoolExecutor(100) def function_a(): output = Queue() fs = [] for _ in range(5): fs.append(pool.submit(do_five_db_calls, output)) pool.wait(fs) def function_b(): output = Queue() fs = [] for _ in range(5): fs.append(pool.submit(do_five_elastic_calls, output)) pool.wait(fs) def function_c(): output = Queue() fs = [] for _ in range(5): fs.append(pool.submit(do_five_io_calls, output)) pool.wait(fs)``` -

Django - Is it possible to add template render conditional based off content inside model field?
I would like to render content inside a template using a conditional that detects for string matching.

Remove objects with duplicated values from Django queryset
I want to remove objects with the same field value from a queryset. I've seen some related answers here, but none of them use the annotate and Min feature and I don't know if that approach is even possible. Imagine I have a 'Book' model with a 'Library' model FK. A Library could have multiple Books with the same title. How can I obtain a list of Books from that Library with different titles and lower price? I've tried different approaches with no success: Book.objects.annotate(count_id=Count('title'), min_price=Min('price')).filter(library__id=21, price=F('min_price')).values_list('title') Example: Having this objects | ID | Title | Price | |:---- |:------:| :-----| | 1 | Trainspotting | 3 | | 2 | The Catcher in the rye | 2 | | 3 | Trainspotting | 1 | | 4 | Lord of the Rings | 5 | | 5 | Trainspotting | 5 | I want to obtain the following queryset: ID Title Price 2 The Catcher in the rye 2 3 Trainspotting 1 4 Lord of the Rings 5 Thanks you very much for your help! -
