###***About Map Rules*** ###***About Map Rules***
1. Struct and struct's fields name should be Pascal style, and the table and column's name default is us 1.Struct and struct's fields name should be Pascal style, and the table and column's name default is us
for example: for example:
The structs Name 'UserInfo' will turn into the table name 'user_info', the same as the keyname. The structs Name 'UserInfo' will turn into the table name 'user_info', the same as the keyname.
If the keyname is 'UserName' will turn into the select colum 'user_name' If the keyname is 'UserName' will turn into the select colum 'user_name'
2. You have two method to change the rule. One is implement your own Map interface according IMapper, you can find the interface in mapper.go and set it to engine.Mapper 2.You have two method to change the rule.
