Django过滤器和模型 [英] Django filter vs get in models

问题描述

$ b

获取

  Entry.objects.get（id__exact = 14）
  

过滤

  Entry.objects.filter（id__exact = 14）
  

上述声明有什么区别？

提前感谢

解决方案

get 只带一个等于你想要的元素，但$ 过滤器带来与您想要的项目相关的所有内容。

过滤器返回很多找到的东西。
只返回一件你要找的东西

，例如：

GET

  Task.objects.get（id = 1，status = 1）
  / pre> 
 
 
过滤器
  Groups.objects.filter（user = 1）
  
 
Im a newbie to Django and would like to understand what is the difference between filter vs get

Get 
Entry.objects.get(id__exact=14)
Filter 
Entry.objects.filter(id__exact=14)
What difference the above statement makes?

Thanks in advance.
解决方案
the get only brings an element that is equal to what you're looking for but the filter brings everything related to that item you want.

filter returns many things found.
get returns only one thing to what you're looking for

for example:

GET
Task.objects.get(id=1,status=1)
Filter
Groups.objects.filter(user=1)
