[new feature]/generate model tag

[imiskolee]

if i has this graphql define

type User{
 id : Int!  #user id
 name:String #user name
login_count:Int! #user login count
}

its will be generated a golang struct

type User struct {
 ID int 
Name *string 
Login_count int 
}

i want generated to

type User struct {
 ID int   `gql:"id,desc:'user id'`
Name *string `gql:"name,desc:'user name'"`
Login_count int `gql:"login_count,desc:'user login count'"`
}

and attach more info to field tag.

we can return desc tag of field when request __schema.

What's the use case?

All of this data and more is already in the schema object, you can fetch it off the generated executable schema es.Schema().

Perhaps mappings need to go from the go struct back to the schema object?

one possible use case is that the generated model may be used directly with mgo or other database lib, without redefine or edit the struct again.

@pandada8 dont direct use graphql layer object for database layer . its really not a good idea. trust me.

I'm going to close this out until there is a good concrete use case.

I don't think gqlgen should be generating your database models, it should be binding to them.

sorry for necro, but how should this be handled, without running into

• having to write a lot of boilerplate
• "desynchronization" of types (say you add a field, you'd now have to add it in 3 places - domain type, db type, gql type)
