bizModel 中未找到 %s.AutoMigrate 调用

Error message

bizModel 中未找到 %s.AutoMigrate 调用

What it means

After ensuring the db variable exists, Injection scans the file for a CallExpr of the form <varDB>.AutoMigrate(...) where varDB is "db" (Business=="") or "<Business>Db". If no such call exists, the injector cannot append the new model argument and returns this error naming the expected receiver.

Solutions

1. Ensure bizModel contains a direct call like db.AutoMigrate() or businessDb.AutoMigrate() matching your Business setting
2. If Business is set, make sure the receiver variable is exactly <Business>Db (e.g. businessDb), not db
3. Avoid chaining the receiver (e.g. global.GVA_DB.WithContext(ctx).AutoMigrate) inside bizModel — use a plain ident variable
4. Re-run injection after fixing the call

Example fix

// before (Business="business")
func bizModel() {
    db.AutoMigrate()
}
// after
func bizModel() {
    businessDb := global.GetGlobalDBByDBName("business")
    businessDb.AutoMigrate()
}

// ensure bizModel has a matching plain-ident AutoMigrate call before injecting
varDB := "db"
if business != "" { varDB = business + "Db" }
// file must contain: <varDB>.AutoMigrate(...) with <varDB> as a bare identifier

if err := inj.Injection(file); err != nil {
    if strings.Contains(err.Error(), "未找到") {
        return fmt.Errorf("add %s.AutoMigrate() to bizModel before running codegen: %w", varDB, err)
    }
    return err
}

When it happens

Trigger: The bizModel function exists but contains no matching AutoMigrate call: the call uses a differently named receiver variable, AutoMigrate is called on a method receiver or chained expression (not a plain ident), or AutoMigrate was removed from bizModel.

Common situations: Business field set to "business" but bizModel still calls db.AutoMigrate instead of businessDb.AutoMigrate; AutoMigrate wrapped in another function so the ident receiver doesn't match; hand-edited bizModel that dropped the call.
