Django DetailView Not Getting Data From Model

Question

I'm using Django 1.8 and Python version 2.7.3

I was following this tutorial as I'm still quite new to Django.

I was able to make the sample site from the tutorial and decided to make my own site using the functions from the tutorial. The site I am making is a simple search site for handymen. My issue is I cannot get DetailView to pull information from the database, I can however get it to pull the information when I put it as ListView and call the information in a for loop. I've gone over both the tutorial files and the files for the site I am making as this works perfectly on the tutorial site, hopefully I'm just skipping over something simple.

Here are my files:

urls.py :

from django.conf.urls import patterns, include, url
from django.views.generic import ListView, DetailView
from search.models import People

urlpatterns = patterns('',
        url(r'^$', ListView.as_view(
            queryset=People.objects.all(),
            template_name="search.html")),

        url(r'^(?P<pk>\d+)$', DetailView.as_view(
            model=People,
            template_name="single.html")),

        url(r'^results/$', ListView.as_view(
            queryset=People.objects.all().order_by("-name")[:5],
            template_name="results.html")),         

)

models.py

from django.db import models

# Create your models here.
class People(models.Model):
    name = models.TextField()
    occupation = models.TextField()
    contact = models.TextField()

    def __unicode__(self):
        return self.name

views.py

from django.shortcuts import render
# Create your views here.

When I searched for this particular issue I came across a lot of people posting up views.py, but I rewatched the tutorial and I never edited views.py yet it worked in the tutorial so I'm not 100% sure what went wrong.

Really appreciate any help or if you need anymore to look at please let me know.

Answer 1

You're not passing anything called "post" to your detail template. Django will use the lower-case name of the model by default, so you can either change your template to use "people", or define context_object_name in the view/url to something more appropriate.
