NDB 查询以字符串开头的结果 [英] NDB querying results that start with a string

问题描述

使用 Google App Engine 的 NDB，我希望查询以用户输入的字符串开头的所有项目.示例:

Working with Google App Engine's NDB, I'm looking to query for all items that start with a user-inputted string. Example:

abc_123
abcdefg
123abc

查询 "abc" 应该返回 abc_123, abcdefg(但是，不是 123abc，因为它没有以abc"开头)

Querying for "abc" should return abc_123, abcdefg (however, not 123abc as it doesn't start with "abc")

我之前将以下代码用于类似但不同的目的:

I previously used the code below for a similar but different purpose:

q = q.filter(order._properties[kw].IN(values_list))

过滤了 values_list 中以 kw 为单位的所有值，我现在正在寻找以 kw 为单位的字符串开头的所有值.

which filtered for all values in values_list that were in kw, I am now looking to filter for all values that start with a string that are in kw.

推荐答案

尝试:

Kind.query(ndb.AND(Kind.property >= "abc", Kind.property <= "abcz"))
