Django 'global name'错误

我正在设置我的第一个Django应用程序 . 我在使数据库模型工作时遇到了一些麻烦 .

这是我的模板：

{% extends 'layouts/base.html' %}
{% load humanize %}
{% block title %}I am a Django God - {{ block.super }}{% endblock %}
{% block content %}
  <h1>Delusions of Grandeur #{{ munber }}</h1>
  <p>They make life EXCITING for {{ thing }}.</p>
  <p>{% if munber %}Number exists!{% else %}booooo{% endif %}</p>
  <p>
    There are {{ munber }} dog{{ munber|pluralize }} and {{ single|apnumber }}
    ocelot{{ single|pluralize }}.
  </p>
{% endblock %}

这是models.py：

from __future__ import unicode_literals

from django.db import models

# Create your models here.
class Thing(models.Model):
    name = models.CharField(max_length=255)
    description = models.TextField()
    slug = models.SlugField(unique=True)

这是views.py：

from django.shortcuts import render

# Create your views here.
def index(request):
    munber = 6
    thing = "Thinnged Nam"
    things = Thing.objects.all()
    return render(request, 'index.html', {
        'munber': munber,
        'single': 1,
        'thing': thing,
        'things':things,
    })

我的错误是
