Django: Trying to click on a link and remove an assigned client - python

Good morning. I am having an issue trying to remove a client from an assigned bed. I created a one-item form called "RoomUpdate" that will allow a user to add a client to a bed that is empty via a dropdown through a ModelChoiceField.
When the bed is full, it does not allow the access to the drop down, instead, I have a link that states "remove client." What I want to happen is when I click that button, it assigns the default value of None to that bed in that room.
What's tricky, at least to my new-ish to Django mind, is how I do this through multiple tables. Having looked for multiple answers and tried different things, I know I've lost track of what I'm doing so I definitely could use some help.
models.py
class Room(models.Model):
room_id = models.AutoField(primary_key=True)
room_number = models.CharField(max_length=5)
shelter_id = models.ForeignKey(Shelter)
max_occupancy = models.CharField(max_length=3)
floor_location = models.CharField(max_length=3)
def __str__(self):
return self.room_number
class Bed(models.Model):
bed_id = models.AutoField(primary_key=True)
room_id = models.ForeignKey(Room, related_name='beds')
bed_size = models.ForeignKey(BedSize)
client_assigned = models.ForeignKey(Clients, null=True, blank=True, default=None)
forms.py
class RoomUpdate(forms.ModelForm):
client_assigned = forms.ModelChoiceField(queryset=Clients.objects.all(), required=False)
#def __init__(self, *args, **kwargs):
#super(RoomUpdate, self).__init__(*args, **kwargs)
#self.fields['client_assigned'].choices.insert(0, ('','---------' ) )
class Meta:
model = Room
fields = ( 'client_assigned', )
views.py
def room_update(request, pk, template_name='shelter/room_edit.html'):
rooms = get_object_or_404(Room, pk=pk)
form = RoomUpdate(request.POST or None, instance=rooms)
beds = Bed.objects.filter(room_id=pk)
if form.is_valid():
form.save()
return redirect('/shelter/')
return render(request, template_name, {'form': form, 'rooms': rooms, 'beds':beds,})
def remove_client(request, pk):
rooms = get_object_or_404(Room, pk=pk)
bed = Bed.objects.filter(room_id=pk)
form = RoomUpdate(request.POST)
template_fail = 'clients/invalid_permissions.html'
if request.method=='POST':
if form.is_valid():
bed.objects.update(client_assigned=None)
bed.save()
else:
return redirect(request, template_fail)
return render_to_response(request, {'rooms': rooms, 'bed': bed})
template
<form action="" method="POST">
{% csrf_token %}
<div class="room box-shadow">
<h4>Room {{ rooms.room_number }}</h4>
<table>
{% for i in rooms.beds.all %}
<tr>
<td>Bed ID: </td>
<td>{{i.bed_id }}</td>
</tr>
<tr>
<td>Bed Size: </td>
<td>{{i.bed_size }}</td>
</tr>
<tr>
<td valign="top">Client: </td>
<td>
{% if i.client_assigned %}
{{ i.client_assigned }}
<br \>
Remove Client
{% else %}
{{ form.client_assigned }}
{% endif %}
</td>
</tr>
<tr>
<td colspan="2">
<hr class="style-two" />
</td>
</tr>
{% endfor %}
<tr>
<td><input type="submit" value="Submit" /></td>
<td></td>
</tr>
</table>
</div>
</form>

I've been playing around with this a bit and making some sort of progress. If I change the url from the same as the edit, I get it to work in that it deletes from the table and redirects the user to a new page.
I would prefer it not redirect the user to a new page, but rather, update the page that's there.
Thoughts?
The new view looks like this:
def remove_client(request, pk, template_name='shelter/test.html'):
bed = Bed.objects.filter(bed_id=pk).update(client_assigned=None)
return render(request, template_name, { 'bed':bed })

Further diving into this, I found a solution I rather like and actually works in a way I wanted but couldn't figure out. Instead of focusing on the room, I realized that I needed to focus on the smaller container -- the bed -- and since it can move around, it would be the better choice.
Currently, this functionality allows me to move beds to different rooms, remove clients by selecting the '----' selector, and allows me to add clients.
So here is the answer I came up with:
forms.py
class RoomUpdate(forms.ModelForm):
bed_id = forms.CharField()
room_id = forms.ModelChoiceField(queryset=Room.objects.all())
bed_size = forms.ModelChoiceField(queryset=BedSize.objects.all(), required=False)
client_assigned = forms.ModelChoiceField(queryset=Clients.objects.all(), required=False)
class Meta:
model = Bed
fields = ('bed_id', 'client_assigned', 'room_id', 'bed_size' )
views.py
def room_update(request, pk, template_name='shelter/room_edit.html'):
beds = get_object_or_404(Bed,pk=pk)
form = RoomUpdate(request.POST or None, instance=beds)
if form.is_valid():
form.save()
return redirect('/shelter/')
return render(request, template_name, {'form': form, 'beds':beds,})
room_edit.html
<form action="" method="POST">{% csrf_token %}
<div class="room box-shadow">
<h4>Room </h4>
<table>
<tr>
<td>Room: </td>
<td>{{ form.room_id }}</td>
</tr>
<tr>
<td>Bed ID: </td>
<td>{{ form.bed_id }}</td>
</tr>
<tr>
<td>Bed Size: </td>
<td>{{ form.bed_size }}</td>
</tr>
<tr>
<td valign="top">Client: </td>
<td>{{ form.client_assigned }}</td>
</tr>
<tr>
<td colspan="2"><hr class="style-two" /></td>
</tr>
<tr>
<td><input type="submit" value="Submit" /></td>
<td></td>
</tr>
</table>
</div>
</form>

Django error value error: The view sub_categories.views.insert_sub_categories didn't return an HttpResponse object. It returned None instead

I am tasked with making a shopping crud project with models Products,categories,sub_categories,size,colors. Categories and subcategories are connected via foreign keys and I am using SERAILIZERS.the problem is that when I try to insert the data into sub Categories it doesnt come in both the database and the webpage
I also tried value = "{{c.category_name}}" as well in select dropdown as well

where am I going wrong in the code?
Try this out and let me know, a few changes you'd require

This error occurs because there is a chance in your function view, that it does not return proper Response or Redirect object. If you send POST request, but the form is not valid, then it will not return anything.
def insert_sub_categories(request):
if request.method == "POST":
...
if form.is_valid():
...
return redirect('sub_categories:show_sub_categories')
else:
print(form.errors)
# HERE YOU MISS REDIRECT/RENDER
else:
...
return render(request,'polls/insert_sub_categories.html',hm)
Also you don't pass SUBCategories.category_name to your serializer. It's required field, so it will never be valid without it. You may try form = SUBCategoriesSerializer(request.POST) instead of adding values one by one.

Trying to add a form to a DetailView

I am writing a Detail View - and the form that is displayed is the particular Track that the user is adding/updating to the CD Entry (It's a CD Library application). The trick is I want to see everything else about the CD on the page as well as the form for the particular track. Having trouble figuring out how to get the form to be just the trac I am adding/updating.
Basically you can enter a CD Title,Artist, and total time of the CD into the CD model. Then the Tracks are stored in the Track Model, with their Foreign Key being the CD they are on.
While looking at a Detail View of the CD, the user can add or update a Particular track via a button. I'm trying to get the update part working.
Model Looks like this:
from django.db import models
from datetime import datetime, timedelta
class Cd(models.Model):
artist_name = models.CharField(max_length=155)
cd_title = models.CharField(max_length=155)
cd_total_time = models.TimeField(default="00:00:00")
cd_total_time_delta = models.DurationField(default=timedelta)
cd_run_time = models.TimeField(default="00:00:00",blank=True)
cd_run_time_delta = models.DurationField(default=timedelta)
cd_remaining_time = models.TimeField(default="00:00:00",blank=True)
cd_remaining_time_delta = models.DurationField(default=timedelta)
def save(self, *args, **kwargs):
super().save(*args,**kwargs)
def __str__(self):
return f"{self.artist_name} : {self.cd_title}"
class Track(models.Model):
cd_id = models.ForeignKey(Cd, on_delete=models.CASCADE,
related_name='cd_tracks',
)
track_title = models.CharField(max_length=50)
track_number = models.IntegerField()
trk_length_time = models.TimeField(null=True,default=None, blank=True)
trk_length_time_delta = models.DurationField(default=timedelta)
trk_run_time = models.TimeField(default="00:00:00",blank=True)
trk_run_time_delta = models.DurationField(default=timedelta)
trk_remaining_time = models.TimeField(default="00:00:00",blank=True)
trk_remaining_time_delta = models.DurationField(default=timedelta)
def save(self, *args, **kwargs):
super().save(*args,**kwargs)
self.cd_id.save()
def __str__(self):
return f"{self.track_title}"
The views.py snippet:
class Track_update(UpdateView):
model = Track
template_name = 'track_update.html'
fields = [ 'cd_id', 'track_title',
'track_number', 'trk_length_time'
]
success_url = "/"
class Cd_DetailView(DetailView):
model = Cd
template_name = 'cd_detail.html'
fields = ['artist_name','cd_title','cd_total_time',
'cd_run_time','cd_remaining_time'
]
class Cd_MixedView(FormMixin, DetailView):
model = Cd
template_name = 'cd_mixed_view.html'
form_class = TrackForm
def get_success_url(self):
return reverse('cd_detail {id}')
def get_context_data(self, **kwargs):
context = super(Cd_MixedView,self).get_context_data(**kwargs)
context['form'] = TrackForm(initial={
'cd_id':self.object
})
return context
def post(self, request, *args, **kwargs):
self.object = self.get_object()
form = self.get_form()
if form.is_valid():
return self.form_valid(form)
else:
return self.form_invalid(form)
def form_valid(self,form):
form.save()
return super(Cd_MixedView, self).form_valid(form)
The urls.py looks like
from django.urls import path
from django.contrib import admin
from .views import (
HomePageView,
Cd_Create,
Cd_Update,
Cd_DetailView,
List_Cds,
Track_Create,
Cd_MixedView,
)
urlpatterns = [
path('', HomePageView.as_view(), name = 'home'),
path('admin/', admin.site.urls),
path('cd/add/', Cd_Create.as_view(), name='cd_new'),

path('track/add/<int:pk>', Cd_MixedView.as_view(), name='cd_mixed_view'),
path('list/', List_Cds.as_view(), name='list_cds'),
]
The template looks like this:
<!-- templates/cd_mixed_view.html -->
{% extends 'base.html' %}
{% load static %}
{% block title %} CD Details{% endblock title %}

So, how do I pass the Track ID into the template, so that I can display the form for THAT track, otherwise
display the track information for all the other tracks.
Any information about how to approach this would be greatly appreciated.
Below is a picture of what the Detail Screen looks like before attempting to update the Track.
Thanks
Did you think about adding the tracking id as a slug, creating another function in views, to pass it? with an 'a' tag, and passing an href, with inside it the foreign key if the track referring to the CD. You could pass the values in the context of the view.

django forloop counter as a variable

So I am trying to make an e-commerce pizza site where when a user adds an item to the basket it is stored as a cookie in the form
cart=[{"id":"2","quantity":"1"},{"id":"3","quantity":"5"},{"id":"5","quantity":"3"},{"id":"5","quantity":"3"}]
And my views.py is...
def cart(request):
cart = request.COOKIES.get('cart')
cart = json.loads(cart)
items =[]
basket=[]
for i in cart:
pizza = Product.objects.filter(pk=i['id']).first()
basket.append(int(i['quantity']))
items.append(pizza)
cart = len(cart)
context = {
"cart":cart,
"pizzas":items,
"basket":basket
}
return render (request, "store/cart.html", context)
And my models.py is ...
class Product(models.Model):
name = models.CharField(max_length=70)
price = models.IntegerField()
description = models.CharField(max_length=300)
image = models.ImageField(upload_to="pizza_images")
def save(self, *args, **kwargs):
super().save()
img = Image.open(self.image.path)
img.save(self.image.path)
def __str__(self):
return f"{self.name}"
In which my template code...
<table>
<thead>
<tr>
<th scope="col" class="small_col">Item</th>
<th id="product_col" scope="col">Product</th>
<th scope="col" class="small_col">Quantity</th>
<th scope="col" class="small_col">Price</th>
</tr>
</thead>
<tbody>
{% for pizza in pizzas %}
<tr>
<td class="center">{{forloop.counter}}</td>
<td>{{pizza.name}}</td>
<td class="quantity_row justify-content-center">
<input class="quantity_input" type="text" value="{{basket.forloop.counter0}}" id="pizza{{forloop.counter}}">
<div class="form_buttons">
<img onclick="add(this.getAttribute('data-attribute'))" data-attribute="pizza{{forloop.counter}}" src="https://s.svgbox.net/hero-outline.svg?ic=plus-sm&fill=000" >
<img onclick="minus(this.getAttribute('data-attribute'))" data-attribute="pizza{{forloop.counter}}" src="https://s.svgbox.net/hero-outline.svg?ic=minus-sm&fill=000">
</div>
</td>
<td class="center">
<h6>$25</h6>
</td>
<td class="small_col">
<a><img class="mb-1" src="https://s.svgbox.net/hero-outline.svg?ic=trash&fill=d90429" width="20" height="20"></a>
</td>
</tr>
{% endfor %}
</tbody>
</table>
And in the input field I want the quantity of the product to be displayed. The line which says...
<input class="quantity_input" type="text" value="{{basket.forloop.counter0}}" id="pizza{{forloop.counter}}">and for somereason the forloop.counter doesn't get the the value of the list and makes it null.
Any ideas on how i could make it work?
Thanks!
{{ basket.forloop.counter0 }} will not work, since this simply will look if basket has a forloop attribute or item, but that is not the case, since both basket.forloop and basket['forloop'] will raise an error.
It is also not a good idea, what you do here is writing business logic in the template. A template should only contain rendering logic: logic that explains how to render data in a pleaseant way, not what data to render.
You can make use of zip(…) [python-doc] to generate 2-tuples of items, and then enumerate over these 2-tuples in the template:
def cart(request):
cart = request.COOKIES.get('cart')
cart = json.loads(cart)
items = []
basket = []
for i in cart:
pizza = Product.objects.filter(pk=i['id']).first()
basket.append(int(i['quantity']))
items.append(pizza)
cart = len(cart)
context = {
"cart":cart,
'pizzabaskets': zip(items, basket),
}
return render (request, 'store/cart.html', context)
and then render this with:
{% for pizza, basket in pizzabaskets %}
<tr>
<td class="center">{{forloop.counter}}</td>
<td>{{pizza.name}}</td>
<td class="quantity_row justify-content-center">
<input class="quantity_input" type="text" value="{{basket}}" id="pizza{{forloop.counter}}">
<div class="form_buttons">
<img onclick="add(this.getAttribute('data-attribute'))" data-attribute="pizza{{forloop.counter}}" src="https://s.svgbox.net/hero-outline.svg?ic=plus-sm&fill=000" >
<img onclick="minus(this.getAttribute('data-attribute'))" data-attribute="pizza{{forloop.counter}}" src="https://s.svgbox.net/hero-outline.svg?ic=minus-sm&fill=000">
</div>
</td>
…
{% endfor %}
the basket it is stored as a cookie.
I would advise not to work with cookies. Cookies can easily be manipulated by the user through request forgery. This thus means that a user can alter the cookies and for example make an order with [{"id":"2","quantity":"-10"},{"id":"3","quantity":"5"},{"id":"5","quantity":"3"}]
so a person can order a negative amount of pizzas to reduce the price. The user has the freedom to submit a different structure and try to look for vulnerabilities. If you want to have data that is attached to the session, it is better to make use of session variables [Django-doc], since these are stored at the server side.

Django-filter: count data

Does anybody knows how can I use count based on selected value using django_filters
Error
'UserFilter' object has no attribute 'count'
My Reference link
views.py
def search(request):
user_list = Person.objects.all()
user_filter = UserFilter(request.GET, queryset=user_list)
count = user_filter.count() #this will return an error
print(count)
return render(request, 'user_list.html', {'filter': user_filter})
filters.py
from django.contrib.auth.models import User
from .models import Person
import django_filters
class UserFilter(django_filters.FilterSet):
class Meta:
model = Person
fields = ['category', 'firstname', 'lastname' ]
user_list.html
{% extends 'base.html' %}
{% block content %}
<form method="get">

<button type="submit" >Search</button>
</form>
<table class="table table-bordered">
<thead>
<tr>
<th>Firstname</th>
<th> Lastname</th>
<th>Caegory</th>
</tr>
</thead>
<tbody>
{% for user in filter.qs %}
<tr>
<td>{{ user.firstname }}</td>

<td>{{ user.category }}</td>
</tr>
{% empty %}

<td colspan="5">No data</td>
</tr>
{% endfor %}
</tbody>
</table>
{% endblock %}
I want to count all the list base from data I filtered
You'll want the count of the resulting queryset, which you can get from the filter's qs property (as you do in your template!).
Change
count = user_filter.count()
to
count = user_filter.qs.count()
You can work with the .qs attribute:
def search(request):
user_list = Person.objects.all()
user_filter = UserFilter(request.GET, queryset=user_list)
count = user_filter.qs.count()
return render(request, 'user_list.html', {'filter': user_filter})
.qs [GitHub] is a property that generates a QuerySet by filtering the original queryset by values in the fields of the FilterSet.

Django: how to get an object of manager on admin page

I am new to Django and I am working on a project. In my project an admin will have the power to assign the project to a manager. So I want to render the name of all the managers from the database so that it will be displayed to the admin.
here is my .html file where I want to render the name of the manager in:
<div class="body table-responsive">
<table class="table table-hover">
<thead>
<tr>
<th>S No.</th>
<th>COMPANY NAME</th>
<th>TEAM MEMBER</th>
<th>EMAIL</th>
<th>ASSIGN TEAM</th>
</tr>
</thead>
<tbody>
{%for team in object%}
<tr>
<form id="form_id" method="POST" action = "{% url 'accept' %}">
{% csrf_token %}
<th scope="row"> {{ forloop.counter }}</th>
<td>{{team.company_name}}</td>
<td>{{team.team_member}}</td>
<td>{{team.email}}</td>
<td>

Here is my model for manager:
class manager(models.Model):
name = models.CharField(max_length= 500)
designation = models.CharField(max_length= 500)
class Meta:
permissions = [
("edit_task", "can edit the task"),
]
def __str__(self):
return self.name
Here is my views.py;
def accept(request):
obj= Create_Team.objects.filter(status='Accept')
if request.method == 'POST':
acc = manager()
manager_id = int(request.POST.get('manager', 1))
acc.manager = manager.objects.get(pk=manager_id)
return render(request, "admin/accept.html", {"object": obj})
In the admins page, I want to display all the names of the managers. I have added the image of the admin page.
I think you forgot to include the managers queryset in the context variable
def accept(request):
obj= Create_Team.objects.filter(status='Accept')
managers = manager.objects.all()
if request.method == 'POST':
acc = manager()
manager_id = int(request.POST.get('manager', 1))
acc.manager = manager.objects.get(pk=manager_id)
return render(request, "admin/accept.html", {"object": obj, "managers": managers})
