注入 gorm import 失败: %w

Error message

注入 gorm import 失败: %w

What it means

Once the AutoMigrate call is found and updated, Injection ensures the model's package is imported by delegating to NewImport(a.ImportPath).Injection(file). This error wraps any failure from that import-injection step (%w preserves the cause), e.g. the ImportPath is empty or the import block could not be updated.

Solutions

1. Set ImportPath to the full import path of the model package (e.g. "github.com/yourorg/server/model/xxx")
2. Unwrap the cause (%w) to see the underlying import-injection failure and fix it
3. Ensure the target file has a standard import declaration block the injector can edit
4. Re-run the injection with a valid ImportPath

Example fix

// before
inj := &ast.PackageInitializeGorm{PackageName: "article", StructName: "Article"}
// after
inj := &ast.PackageInitializeGorm{PackageName: "article", StructName: "Article", ImportPath: "server/model/article"}

if inj.ImportPath == "" {
    return fmt.Errorf("ImportPath is required")
}
// optionally verify the package resolves:
// go/packages or go/build.Import(inj.ImportPath, "", build.FindOnly)

if err := inj.Injection(file); err != nil {
    var inner error
    if errors.Unwrap(err) != nil { inner = errors.Unwrap(err) }
    return fmt.Errorf("check ImportPath %q: %w (cause: %v)", inj.ImportPath, err, inner)
}

When it happens

Trigger: PackageInitializeGorm.ImportPath is empty/blank or malformed, or the underlying import injector fails to locate/modify the file's import declaration.

Common situations: Struct field ImportPath forgotten when constructing PackageInitializeGorm; typo in the module path; target file has no import block the injector recognizes.
