Question

我在视图中传递一个字符串参数，但它无效。

url(r'^users/(?P<user_type>\w+)/$', views.users, name='users'),
url(r'^users/$', views.users, name='users')

视图是： -

def users(request, user_type=None):

链接是： -

<a href="{% url 'users' %}">All Users</a>
<a href="{% url 'users' customers %}">Customers</a>
<a href="{% url 'users' promoters %}">Promoters</a>

但是当我访问没有参数的视图时它给出错误

Reverse for 'users' with arguments '('',)' and keyword arguments '{}' not found. 2 pattern(s) tried: ['administrator/users/$', 'administrator/users/(?P<user_type>\\w+)/$']

Exception Value: Reverse for 'users' with arguments '('',)' and keyword arguments '{}' not found. 2 pattern(s) tried: ['administrator/users/$', 'administrator/users/(?P<user_type>\\w+)/$']

Answer 1

使用此选项并检查

url(r'^users/(?P<user_type>\w+)/$', views.users, name='users_type'),
url(r'^users/$', views.users, name='users')

链接是：

<a href="{% url 'users' %}">All Users</a>
<a href="{% url 'users_type' "customers" %}">Customers</a>
<a href="{% url 'users_type' "promoters" %}">Promoters</a>

字符串参数传递在django1.9中不起作用
