Django得到了一个意想不到的关键字参数

Question

我想创建一个存档，所以我传递给视图参数年和月。

但是，我得到一个错误与下面的代码，我想不出这意味着什么，如何解决这个问题：

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 

什么可能是错误的？

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<year_id>\d+)/(?P<month_id>\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

<h3>Archivo</h3> 
     <p> 
     {% for month in months %} 
     {% ifchanged month.0 %} {{ month.0 }} <br /> {% endifchanged %} 
     <a href="/blog/archives/{{month.0}}/{{month.1}}">{{ month.2 }}</a> <br /> 
     {% endfor %} 
     </p>

Answer 1

也有一些是不对您的参数名称：

def archive(request, year, month): 

通过year_id和month_id更换year和month，它应该工作。

编辑：

你的第二个错误，并据此this question，您archive()视图不返回正确的响应。

这里是你的代码，固定：

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：

您的模板无法通过months迭代，因为变种不存在背景：

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

待办事项你看到了区别？在第一个变量名称（“Months”）中使用大写字母，而呈现的大小写敏感的模板查找小写字母变量（“months”）。
