Why is my Heroku deployment not recognising my Procfile?
I'm trying to deploy my app using Heroku. I tried via CLI and also graphically in their user portal. I get this problem in the build log: Procfile declares types -> (none) It's not reading my Procfile.

Why I send data to Django POST but fetch them in GET?
I am new to Django and built a simple test today. def login_web(request): request.encoding = "utf-8" print("body : ", request.body) print("POST : ", request.POST) print("GET : ", request.GET) username = request.POST.get("username") password = request.POST.get("password") print(username) print(password) user = auth.authenticate(username=username, password=password) if user is not None and user.is_active: print("YR1") auth.login(request, user) return JsonResponse({"foo": "bar1"}) else: print("IM2") return JsonResponse({"foo": "bar2"}) I used Postman to send post request to it. But the result is very confusing. body : b'' POST : <QueryDict: {}> GET : <QueryDict: {'username': ['chivier'], 'password': ['Chivyham07313']}> None None IM2 I should get them in request.POST but why they appear in request.GET. -

Django 2.0.8 crashes when resetting passwords are unequal
On of web projects that use Django 2.0.8. I forgot my password. So I decided to reset it using the "Forgotten password" wizard. After receiving the mail and opening the link, I got to the form where I need to insert my new password (field password1) and confirm it again (password2). As I made a mistake with writing two unequal passwords (password1=MyNewPass123), (password2=MyNewPass12), the app crashed with the error: ValueError at /auth/password/reset/confirm/<CODE>/set-password/ Need 2 values to unpack in for loop; got 17. <PATH>\lib\site-packages\django\template\defaulttags.py in render, line 202 So I went back and tried again, this time using two equal (valid) passwords which were successful. I repeated the password-reset step, using a new password (again 2 unequal inputs) and yet, it crashed. Searching for any bugs or related issued did not return any result. What is the main question here: Why does ForNode render in defaulttags.py receive so many items, just because of two unequal values.. What could be the solution for this? ForNode in defaulttags.py: class ForNode(Node): child_nodelists = ('nodelist_loop', 'nodelist_empty') def __init__(self, loopvars, sequence, is_reversed, nodelist_loop, nodelist_empty=None): self.loopvars, self.sequence = loopvars, sequence self.is_reversed = is_reversed self.nodelist_loop = nodelist_loop if nodelist_empty is None: self.nodelist_empty = NodeList() else: self.nodelist_empty = nodelist_empty … -

How to get a Count based on a subquery?

How do you properly clone something in Javascript/JQuery?
I'm using .clone() to duplicate a form. I make small changes to the clone and then place it after the last form. As you can see from the screenshot it's mostly working; they look identical. The application (Django/Python) can process the clone as well once I press save. The problem is the calendar widget does not open when clicked (on the clone form). It does open if I click on the widget button for a form that already exists on the page when it first loads (not a clone). But on my clones the date picker does not open. What it should look like after I click on it (instead nothing happens): The cloned html seems to look identical in all the right ways. Existing form: Clone: Is something missing from the cloned html? Or is there something behind the scenes that is not working? I just don't understand what is broken here. JS/JQuery: function cloneMore(selector, prefix,form_class) { var newElement = $(selector).clone(true); var total = $('#id_' + prefix + '-TOTAL_FORMS').val(); newElement.find(':input:not([type=button]):not([type=submit]):not([type=reset])').each(function() { var name = $(this).attr('name').replace('-' + (total-1) + '-', '-' + total + '-'); var id = 'id_' + name; $(this).attr({'name': name, 'id': id}).val('').removeAttr('checked'); }); newElement.find('label').each(function() { var forValue … -

What does "render" mean in Django?
What does it mean to "render a template" or to "render a form" in Django? Example 1: "Generally a view retrieves data according to the parameters, loads a template and renders the template with the retrieved data. Example 2: "Rendering a form in a template involves nearly the same work as rendering any other kind of object" Would the meaning of render in the above two examples be to "provide" or give"? -
