Error message

已经创建过此数据结构或重复简称,请勿重复创建!

What it means

autoCodeTemplate.Preview checks AutocodeHistory.Repeat for the given business DB, struct name, abbreviation, and package; if a matching history exists and the request did not opt in via IsAdd, preview is blocked with "已经创建过此数据结构或重复简称,请勿重复创建!" (structure already created or duplicate abbreviation, do not duplicate). Unlike Create it also flags duplicate abbreviations.

Solutions

1. Set info.IsAdd = true in the request to allow regeneration/preview of an existing structure.
2. Change the abbreviation to a unique value if it collides with another struct.
3. Remove the obsolete autocode history entry if the old structure is no longer wanted.
4. Use a different package if the struct legitimately belongs elsewhere.

Example fix

// before
{"structName":"User","abbreviation":"user","isAdd":false}
// after
{"structName":"User","abbreviation":"user","isAdd":true}

if AutocodeHistory.Repeat(ctx, info.BusinessDB, info.StructName, info.Abbreviation, info.Package) && !info.IsAdd {
    return errors.New("结构或简称已存在, 请设置 isAdd=true 或更换简称")
}
// safe to call Preview

codes, err := autoCodeService.PreviewAutoCode(ctx, info)
if err != nil {
    if strings.Contains(err.Error(), "重复简称") {
        return fmt.Errorf("请设置 isAdd=true 或更换 abbreviation: %w", err)
    }
    return err
}

When it happens

Trigger: Previewing generation for a struct/abbreviation that already has autocode history without setting IsAdd=true; reusing an abbreviation already taken by another struct in the same package.

Common situations: Iterating on a previously generated table and previewing again without the add/overwrite flag; two structs sharing an abbreviation (e.g. both "user") causing model file name collisions.
