Ecto update_all 示例
Ecto update_all example
我想更新所有匹配查询的字段
MyModel
|> where([m], m.state == "begin")
|> update([set: %{state: "commit"}])
|> Repo.update_all()
但我得到:
malformed update `[set: %{state: "commit"}]` in query expression, expected a keyword list with set/push/pop as keys with field-value pairs as values
我这里做错了什么?
我不确定你的 update
函数是做什么的,但你可以尝试直接传递给 Repo.update_all()
Repo.update_all(from(m in MyModel, where: m.state == "begin", update: [set: [%{state: "commit"}]))
