improperly configured at /18/delete, Django views issue

I have searched through the other questions similar to my own problem and have come to no solution so im hoping someone can help me figure out where i went wrong.
I'm trying to implement a delete post option in my blog program but it is throwing the following error once you click the 'delete' button:
ImproperlyConfigured at /18/delete/
Deletepost is missing a QuerySet. Define Deletepost.model, Deletepost.queryset, or override Deletepost.get_queryset().
I am nearly sure its a problem with my URLS.py though what exactly i cannot figure out.
the following is the code in question:
Views.py
# delete post
class Deletepost(LoginRequiredMixin, DeleteView):
form_class = Post
success_url = reverse_lazy('blog:home')
template_name = 'templates/post.html'
def test_func(self):
post = self.get_object()
if self.request.user == post.author:
return True
return False
urls.py
urlpatterns = [
# home
path('', views.postslist.as_view(), name='home'),
# add post
path('blog_post/', views.PostCreateView.as_view(), name='blog_post'),

path('<slug:slug>/', views.postdetail.as_view(), name='post_detail'),
# edit post
path('<slug:slug>/edit/', views.Editpost.as_view(), name='edit_post'),
# delete post

Any ideas?

I think it should be model not form_class so:
class Deletepost(LoginRequiredMixin, DeleteView):
model = Post
success_url = reverse_lazy('blog:home')
template_name = 'templates/post.html'
def test_func(self):
post = self.get_object()
if self.request.user == post.author:
return True
return False

#SunderamDubey's answer is correct. The test_func will however not run, since this is method of the UserPassesTestMixin [Django-doc], not LoginRequiredMixin.
But using a test function as is done here is not efficient: it will fetch the same object twice from the database. You can simply restrict the queryset, like:
from django.contrib.auth.mixins import LoginRequiredMixin
from django.urls import reverse_lazy
from django.views.generic import DeleteView
class DeletePostView(LoginRequiredMixin, DeleteView):
model = Post
success_url = reverse_lazy('blog:home')
template_name = 'templates/post.html'
def get_queryset(self, *args, **kwargs):
return (
super().get_queryset(*args, **kwargs).filter(author=self.request.user)
)
This will do filtering at the database side, and thus return a 404 in case the logged in user is not the author of the Post object you want to delete.
In the template, you will need to make a mini-form to make a POST request, for example:
<form method="post" action="{% url 'delete_post' post.id %}">
{% csrf_token %}
<button class="btn btn-outline-danger" type="submit">Delete</button>
</form>

In my opinion, you should change url to below
'path('delete/int:pk', views.Deletepost.as_view(), name='delete_post'),'
if didn't work you can do this
def delete_post(request, post_id):
post = Post.objects.get(pk=post_id)
post.delete()
return redirect('blog:home')

Django - ListView with form, How to redirect back to the Form page?

So, I have a ListView with exercices list (paginated 1 per page). In each page I have few input the user need to fill up. I managed to find a solution to how to attached the ListView with the Form but i cant find a solution on how to stay on the same page after the submit.
url's:
urlpatterns = [
path('programs/', ProgramListView.as_view(), name='web-programs'),
path('programs/<int:pk>/', ExerciseListView.as_view(), name='program-detail'),
path('data/', views.add_data, name='data-submit'),
views.py (updated with def form_valid):
class ExerciseListView(LoginRequiredMixin,FormMixin, ListView):
model = Exercise
context_object_name = 'exercises'
form_class = DataForm
paginate_by = 1
def get_queryset(self):
program_num = get_object_or_404(Program, pk=self.kwargs.get('pk'))
return Exercise.objects.filter(program=program_num)
def form_valid(self, dataform):
program_num = get_object_or_404(Program, pk=self.kwargs.get('pk'))
exercises = Exercise.objects.filter(program=program_num)
for exe in exercises:
dataform.instance.exercise = exe.pk
return super(ExerciseListView, self).form_valid(dataform)
def add_data(request):
if request.method == "POST":
form = DataForm(request.POST)
if form.is_valid():
form.save()
# Data.objects.create(address=form.cleaned_data['form'])
return redirect(?)

forms.py:
class DataForm(forms.ModelForm):
class Meta:
model = Data
fields = ['exercise', 'set_number', 'spo2', 'hr']
In the views.py, i left the "redirect" with "?" because i don't know what to add there.
I can't change the "action" in the template.html because this link is for def add_data(request)
so it will save my inputs.
Once i submit, it saves the new data to my DB but i don't know how to stay on the same page for continue my exercises.
Thanks.

You have Program in Exercise so use it get program id looking at your DataForm you have exercise field if am not wrong is foreign-key
from django.shortcuts import redirect, reverse
def add_data(request):
page=request.GET.get('page')
page='?page={}'.format(page) if page else ''
if request.method == "POST":
form = DataForm(request.POST)
if form.is_valid():
data=form.save()
return redirect(reverse('program-detail', kwargs={'pk':data.exercise.program.pk})+ page)
For redirecting to same page you check and pass page parmameter in url in form action like
<form action="{% url 'data-submit' %}{%if request.GET.page%}?page={{request.GET.page}}{%endif%}" method="POST" enctype="multipart/form-data">{% csrf_token %}

You need to use jQuery to achieve this result. Download it, paste to js folder and add it to program/base.html
<script src="{% static 'js/jquery-3.5.1.min.js' %}"></script>
I'd like to recommend you to add a js block into base.html
somewhere at the bottom of the file
{% block js %}{% endblock js %}
Then, do this:
<block js>
<script>
$("#submit-btn").submit(function(event) {
// prevent default action, so no page refreshing
event.preventDefault();
var form = $(this);
var posting = $.post( form.attr('action'), form.serialize() );
posting.done(function(data) {
// done
});
posting.fail(function(data) {
// fail
});
});
</script>
<endblock>
...
<form action="{% url 'data-submit' %}" method="POST" enctype="multipart/form-data">
{% csrf_token %}
<fieldset class="form-group">
<legend class="border-bottom mb-4">Exercise Measurements</legend>
{{ form|crispy }}
</fieldset>
<div class="form-group">
<button class="btn btn-outline-info" id="submit-btn" type="submit">Save</button>
</div>
</form>

reCAPTCHA not stopping users logging in

I am trying to use Google reCAPTCHA for my login form to prevent spam. After following the necessary steps to get it all working, users can still login. They can fill out there details and login with out ticking the checkbox which isn't correct.
I think it might be the placement in the DOM so I tried moving it around and that didn't work.
CODE:
{% extends 'public/base.html' %}
{% load staticfiles %}
{% load crispy_forms_tags %}
{% block head %}
<link rel="stylesheet" type="text/css" href="{% static "public/css/auth.css" %}" />
{% endblock %}
{% block content %}
<div class="container mt-5 mb-5 login-container">
<form method="POST">
{% csrf_token %}
<fieldset class="form-group mt-4">
<legend class="border-bottom mb-4">Log In</legend>
{{ form|crispy }}
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
<div class="g-recaptcha" data-sitekey="################################
"></div>
</fieldset>
<div class="form-group">
<button class="btn btn-success" type="submit">Login</button>
<small class="text-muted ml-2">
Forgot Password?
</small>
</div>
</form>
<div class="border-top pt-3 mb-4">
<small class="text-muted">
Need An Account? <a class="ml-2" href="{% url 'register' %}">Sign Up Now</a>
</small>
</div>
</div>
{% endblock %}```
Thanks.

When you use the captcha, a textarea is added dynamically inside <div class="g-recaptcha">.
That textarea is not visible and by default has id="g-recaptcha-response".
You can get it with:
document.getElementById('g-recaptcha-response').value
In your login form you have to check if that textarea has a value or not. If it has a value then user has used successfully the captcha and can continue with the login process.
Something like this:
<form onsubmit="return check_form()">
...
</form>
<script>
function check_form()
{
return document.getElementById('g-recaptcha-response').value != '';
}
</script>
If check_form() returns FALSE, then the form is not submitted.

Request in Flask from a Form in HTML is returning None Value, What should I Do?

I am getting no value on request in flask. It is returning None value.
I have tried changing the method but no use.
The flask code:
#app.route("/login/user/book")
def searchbook():
bookname=request.form.get("search")
return render_template("message.html",heading=bookname ,message=" ")
The webpage:
{% extends "layout.html" %}
{% block heading %}Welcome to BookSarkar{% endblock %}
{% block body %}
<p>Welcome {{ name }}</p>
<form action="{{ url_for('searchbook') }}" method="get" class="form-group">
<div class="form-group">
<input type="text" name="search" class="form-control col-md-6 mt-5 mx-auto" placeholder="Search books">
<p style="text-align:center;">
<button type ="submit" class="btn btn-primary mt-2 mx-auto">Search</button>
</p>
</div>
</form>
<div class="fixed-top m-2">
<a class="btn btn-outline-primary" href="{{ url_for('logout') }}" role="button" style="float:right;">Log out</a>
</div>
{% endblock %}
The message webpage:
{% extends "layout.html" %}
{% block heading %}{{ heading }}{% endblock %}
{% block body %}
{{ message }}
<a class="btn btn-primary" href="{{ url_for('index') }}" role="button">Return to Home Page</a>
{% endblock %}
The layout page has no bugs as all other pages are working fine. I expected the webpage to show the given input but it is showing None

request.form contains values submitted via post or put, while your form uses get. Try using request.args.get("search") instead of request.form.get("search")
