I wonder what should be written to model
.ORM- multi-table association-and some business logic algorithms-complex queries
suggest that model can be divided into three categories: logic layer, cache layer, and data layer
Controller. After the request comes in, you first use the logic layer under model to deal with the business logic. When you need to call data, you call the cache layer and the data layer respectively. These two can only write code that interacts with the database and cache
according to my understanding, the model layer is only responsible for the interaction with the database, such as fetching data, there should not be too many logical operations, logical operations can be written in the C layer, or can be sub-packaged, so it is easier to maintain and expand.
I don't think there are strict restrictions on this. Different teams or different individuals have different understandings.
