ServerSide wrapper

[hgrecco]

Is there a way to implement a (let's call it) ServerSide object (similar to Option) to tell diesel that a particular field should be ignored from any insert/update?

The example from the guide would then become:

#[derive(Queryable, Insertable)]
pub struct Post {
    pub id: ServerSide<i32>,
    pub title: String,
    pub body: String,
    pub published: bool,
}

and then use it in insert as:

    let new_post = NewPost {
        id: None // Or another special value
        title: title,
        body: body,
        published: false
    };

    diesel::insert(&new_post).into(posts::table)
        .get_result(conn)
        .expect("Error saving new post")

The same could be applied to other fields like created_at and updated_at.

What is your reasoning to make this a wrapper struct and not an attribute? Am I missing something or is this a subset of #860 (and thus a dupe of it)?

Yeah this seems like a duplicate of #860 to me.
