django: blog() missing 1 required positional argument: 'blog_id'

Question

I am attempting to add a blog to an existing test website, but I am receiving the following error message:

blog() missing 1 required positional argument: 'blog_id'

This may be a simple mistake I have made, but I am stumped at what I have done incorrectly and how to fix this. I have searched google and SO, but I haven't found a suitable reference.

Here is my models class:

class Blog(models.Model):
    blog_title = models.CharField(null=False, blank=False, max_length=150, unique=True)
    blog_description = models.CharField(null=False, blank=False, max_length=500)
    blog_script = models.CharField(null=True, blank=True, max_length=5000)
    blog_date_released = models.DateField(null=False, blank=False)
    blog_tags = models.CharField(null=True, blank=True, max_length=150)
    blog_video_url = models.URLField(null=False, blank=False, max_length=250)
    blog_timestamp_added = models.DateTimeField(auto_now_add=True, auto_now=False)
    blog_timestamp_updated = models.DateTimeField(auto_now=True, auto_now_add=False)

Here is my views.py file:

from django.shortcuts import render
from django.utils.translation import ugettext_lazy as _
from myapp.core.decorators import *
from myapp.core.models import Blog

def blog(request, blog_id):
    blog = Blog.objects.get(pk=blog_id)
    ....
    return render(request, 'blog/blog.html', {
        'blog': blog,
        'display_default_language': the_display_default_language,
        'language_versions': language_versions,
        'language_versions_num_enabled': language_versions_num_enabled,
        'language_versions_num_total': language_versions_num_total,
        'var_page_title': _("Blog"),
    })

Here is mu urls.py file:

urlpatterns = [
    ....
    url(r'^blog/blog/$', views.blog, name='blog'),
]

Any help will be greatly appreciated.

您需要从您的网址传递blog_id：

from . import views

url(r'^blog/(?P<blog_id>\d+)/$',views.blog, name='blogs'),
