我的模型有一个称为user_ids的外地,这是一个阵列。 我如何能够在<编码>用户_ids上找到包括某种笔迹在内的所有记录?
I m 采用铁路3.0.1 &Rir.1.9.2p0。
You can use something like this scope:
scope :some_scope_name, lambda {|user_id| where(["user_ids RLIKE ?", user_id])}
I used this type of scope in project, where I have to find all records with list_ids column match some criteria.
或者你可以找到与以下方法相同的方法:[”用户_ids RLIKE?”,标准]
