Renaming struct params for db use

[xelab04]

This is possibly a bit of a complex issue. I have a model I defined here:

#[model]
pub struct Meetup {
    #[model(primary_key)]
    pub id: Auto<i32>,
    pub r#type: LimitedString<255>,
    pub title: LimitedString<255>,
    pub r#abstract: String,
}

For a field like title, I have no issues. But for field names such as type or abstract, which are reserved keywords, I need to add the r# prefix.
And when the migration is created, it takes literally r#type. Also, there are times where you can have a parameter of a certain name but want to map it to a different name in the db.

Maybe having something like the following would be useful?

#[model]
pub struct Meetup {
    #[model(primary_key)]
    pub id: Auto<i32>,
    #[dbfield("type")]
    pub r#type: LimitedString<255>,
}

Ah, good call - support for raw identifiers will be added in #485 (currently very WIP).

Renaming fields/models is a separate feature that also should be implemented. Tagging good first issue as it sounds relatively easy to add.

I saw the PR notification from the Discord, thanks a lot! I promise once I'm done with this first project I'll submit some PRs of my own!

Hi, I am trying to add the custom db field and need a couple pointers if you don't mind. I am looking at your draft PR, and working from there.

let table_name = if let Some(table_name) = &args.table_name {
    table_name.clone()
} else {
    unraw_original_name.to_snake_case()
};

What is table name here? I see it refer to a ModelArgs struct further up the model.rs file. My IDE gives me a description of the model_type parameter, but not table_name.
