Hello guys, i wonder how you guys are defining your Business Models (DTOs) for the different use-cases and how you are defining the constructors of the DTOs for use with the Jooq Typesafe Api (convertFrom, Records.mapping, mapping, ...)
For example: My DTOs have 3 kinds of fields: - Simple Database-Fields (Integer, String, BigDecimal, ...) created by the Codegen - Complex Database-Fields resolved by Joins (UserDTO, List<ProductLangDTO>, ...) not! created by the Codegen - Control Fields with no direct relation to the database (deleteFlag=true, insertFlag=true) Should the DTO Constructors contain all those fields, or only those fields that are needed for the Jooq Typesafe Mapping ? Do i need to create multiple DTO Constructory for different use-cases of Queries ? For example: - Query1 gets all products with all langs and the user - Query2 gets only one product, and only some fields of it Would i need to define a constructor for Query1 and a constructor for Query2 or should i defined two separate ProductDTOs (one with only the fields for query1, and one with only the fields for query2) ? Has someone also got experience with those questions and how to solve them? Before using the Jooq Typesafe API i always did the "into()" mapping, where those questions were not relevant because everything was automagically mapped. But typesafety benefits are pretty important i think, so i now try to use the typesafe api more. I also wonder if my way ot using the "into()" mapping is safe enough. I sometimes have no other choice but to use "into()" to make AbstractDAO Abstraction possible. I always do: // first: map to codegenerated jooq-table - ProductRecord rec = record.into(Product) // second: map to DTO which implements the same interface - rec.into(ProductDTO.class) as the ProductRecord (should be safe) somehow i assume that with this kind of two-way "into()" jooq should be able to always reflect correctly (at least it did for me always when i did it that way. When i map "record.into(ProductDTO.class)" this is dangerous though, because sometimes the reflect-api would reflect fields from an other joined-table with the same name (clientId) into the wrong DTO. So this way to reflect directly seems to be dangerous. Sorry for asking so many stuff, but maybe someone has some ideas or already solved those questions ;) -- You received this message because you are subscribed to the Google Groups "jOOQ User Group" group.
