Django得到了一个意外的关键字参数

我正在尝试创建一个存档,所以我将参数年份和月份传递给视图.

但是,我在下面的代码中遇到错误,我无法弄清楚它的含义以及如何解决它:

Exception Type: TypeError
Exception Value:    archive() got an unexpected keyword argument 'year_id'
Exception Location: /usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py in get_response, line 115

有什么不对？

Views.py

def mkmonth_lst():
if not Post.objects.count(): 
    return []

# set up vars
year, month = time.localtime()[:2]
first = Post.objects.order_by("created")[0]
fyear = first.created.year
fmonth = first.created.month
months = []

# loop over years and months
for y in range(year, fyear-1, -1):
    start, end = 12, 0
    if y == year: start = month
    if y == fyear: end = fmonth-1

    for m in range(start, end, -1):
        months.append((y, m, month_name[m]))

return months

def archive(request, year, month):
posts = Post.objects.filter(created__year=year, created__month=month)
context = {'PostList': posts, 'Months': mkmonth_lst()}

return(render, 'archives.html', context)

urls.py

url(r'^archives/(?P\d+)/(?P\d+)$', views.archive, name='archives'),

更新:

Models.py

class Post(models.Model):
title = models.CharField(max_length=100)
body = models.TextField()
created = models.DateTimeField(auto_now_add=True)
url = models.URLField(null=True, blank=True)
video = models.FileField(upload_to = 'video', verbose_name = 'Video', null=True, blank=True)
picture = models.ImageField(upload_to = 'post', verbose_name = 'Picture')
tags = TaggableManager()

def __unicode__(self):
    return self.title

模板

Archivo
      

        {% for month in months %}
        {% ifchanged month.0 %} {{ month.0 }} 
 {% endifchanged %}
        {{ month.2 }} 

        {% endfor %}
      

更新2:错误

参数名称有问题:

 def archive(request, year, month):

替换year和monthby year_id和month_id它应该工作.

编辑:

对于您的第二个错误,以及相应的问题,您的archive()视图不会返回正确的响应.

这是你的代码,修复:

from django.shortcuts import render_to_response

def archive(request, year_id, month_id):
    posts = Post.objects.filter(created__year=year_id, created__month=month_id)
    context = {'PostList': posts, 'Months': mkmonth_lst()}

    # the error was here
    return render_to_response('archives.html', context)

编辑2:

您的模板无法迭代, months因为var在上下文中不存在:

context = {'PostList': posts, 'Months': mkmonth_lst()} # Not correct
context = {'postList': posts, 'months': mkmonth_lst()} # Correct

你看得到差别吗 ？您在第一个变量名称("Months")中使用大写字母,而呈现的模板(区分大小写)查找小写变量("months").
