不推荐对 url() 的字符串视图参数的支持，并将在 Django 1.10 中删除。改为传递可调用对象

Question

这是我发出警告的代码。

它对urlpatterns 中的"posts.views.post_list" 等字符串发出警告，并建议代替字符串传递可调用对象。我需要修复或删除该警告。

from django.conf.urls import url
#from django.contrib import admin

from . import views

urlpatterns = [
   url(r'^$', "posts.views.post_list"),
   url(r'^create/$', "posts.views.post_create"),
   url(r'^detail/$', "posts.views.post_detail"),
   url(r'^update/$', "posts.views.post_update"),
   url(r'^delete/$', "posts.views.post_delete"),    
   #url(r'^posts/$', "<app_name>.<views_py>.<function_name>"),
]

Answer 1

谢谢大家，我自己修复了这个警告。现在它运行良好，没有任何警告。

from django.conf.urls import url
#from django.contrib import admin

from .views import(
  post_list,
  post_create,
  post_detail,
  post_update,
  post_delete
)

urlpatterns = [
  url(r'^$', post_list),
  url(r'^create/$', post_create),
  url(r'^detail/$', post_detail),
  url(r'^update/$', post_update),
  url(r'^delete/$', post_delete),    
  #url(r'^posts/$', "<app_name>.<views_py>.<function_name>"),
]

你应该传递真正的函数，而不是由函数名组成的字符串：

from django.conf.urls import url
#from django.contrib import admin

from . import views

urlpatterns = [
   url(r'^$', views.post_list),
   url(r'^create/$', views.post_create),
   url(r'^detail/$', views.post_detail),
   url(r'^update/$', views.post_update),
   url(r'^delete/$', views.post_delete),    
   #url(r'^posts/$', <views_py>.<function_name>),
]

正如警告所说，将字符串传递给 url 已被弃用 (docs)。

您必须传递可调用对象。这意味着导入函数并直接传递它：

 urlpatterns = [
   url(r'^$', views.post_list),
   url(r'^create/$', views.post_create),
   url(r'^detail/$', views.post_detail),
   url(r'^update/$', views.post_update),
   url(r'^delete/$', views.post_delete),    
]
