Having problems with a query in Django - django

Question

I'm building my first app within Django and I'm trying to query a "load" based on the company that i've attached to the load. Here's the model in question.
class Load(models.Model):
company = models.ForeignKey(UserCompany, null=True,
on_delete=models.CASCADE)
load_number = models.IntegerField()
carrier = models.CharField(max_length=255)
pickup_date = models.DateField()
delivery_date = models.DateField()
shipper = models.CharField(max_length=255)
consignee = models.CharField(max_length=255)
po_number = models.CharField(max_length=255)
pu_number = models.CharField(max_length=255)
pieces = models.IntegerField()
description = models.TextField()
date_created = models.DateTimeField(blank=True, null=True)
def publish(self):
self.date_created = timezone.now()
self.save()
def __str__(self):
return str(self.load_number)
Now I'm trying to display a list on a page, but only display the loads attached to a specific company. The user needs to be attached to that company as well so here are my user models.
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.db import models
from django.contrib.auth.models import User
# Create your models here.
class UserCompany(models.Model):
company_name = models.CharField(max_length=200)
def __unicode__(self):
return self.company_name
def __str__(self):
return self.company_name
# User Model
class UserProfileInfo(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
# Additional Classes
profile_pic = models.ImageField(upload_to='profile_pics',
blank=True)
company = models.ForeignKey(UserCompany,
null=True,on_delete=models.CASCADE)
def __str__(self):
return self.user.username
Then i'm trying to query the "loads" within this view.
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.shortcuts import render, get_object_or_404
from django.shortcuts import redirect
import datetime
from django.conf import settings
from django.utils import timezone
from django.http import HttpResponse
from django.views.generic import View, DetailView
from easy_pdf.views import PDFTemplateResponseMixin
from loads.models import Load
from .forms import LoadForm
from users.models import UserCompany, UserProfileInfo
# Create your views here.
class PDFUserDetailView(PDFTemplateResponseMixin, DetailView):
model = Load
template_name = 'loads/load_pdf.html'
def load_list(request):
loads =
Load.objects.filter(company=request.company).order_by('date_created')
return render(request, 'loads/load_list.html', {'loads':loads})
I was able to get the query working based on the user, so my thought is that this query would be the same. This is not the case. I have a feeling that i'm referencing company wrong and maybe I somehow need to filter 2 more levels down all the way to the original UserCompany class, just not sure how to accomplish that.
The error that i'm getting is:
AttributeError: 'WSGIRequest' object has no attribute 'company'

Answer 1

request.company isn't a thing you can do. Instead of
Load.objects.filter(company=request.company).order_by('date_created')
You try something like this:
current_user = request.user
company = current_user.userprofileinfo.company
Load.objects.filter(company=company).order_by('date_created')
request just holds information about the current request which you can read more about here
