Django has provided us with form validation, so let's take a look at the following: Wu Sir Blog: http://www.cnblogs.com/wupeiqi/articles/5246483.html
After you create the Django project, create the app.
Configure Urls:

  10. urlpatterns = [
    11. 
   
  
  11. 
  
  12.  url(r‘^admin/‘, admin.site.urls),
    13. 
   
  
  13. 
  
  14.  url(r‘^login/‘, views.login),
    15. 
   
  
  15. 
  
  16. ]
    17.

    27. 
   
  
  27. 
  
  28.  ret = obj.is_valid()
    29. 
   
  
  29. 
  
  30.  print(ret,obj.data)
    31. 
   
  
  31.
