从Mongo Engine中的ListfField中删除嵌入式文档

Question

我还没有找到明确的答案，但问题是我需要删除和/或更新列表字段中的嵌入式文档。所以，如果我有一个架构：

-Team
    -Players
        -name
        -number

我该如何删除或更新玩家？

Answer 1

It should look like this (note these are raw mongodb queries):

# To update the number:
db.team.update({ "name": "FC Barcelona", "players.name" : "Lionel Messi" }, { $set: { "players.$.number" : 11 }})

# To remove the player from the list:
db.team.update({ "name": "FC Barcelona", "players.name" : "Cesc Fabregas" }, { $pull: { "players.name" : "Cesc Fabregas" }})
