Package为空!

Error message

Package为空!

What it means

Pretreatment validates an AutoCode (code generator) request before Preview/Create. The Package field names the Go package the generated code belongs to and must be non-empty; this check runs before the value is normalized (first letter uppercased etc.). An empty Package means the generator cannot place the generated files, so it short-circuits with this error.

Solutions

1. Set the package field in the code-generation form (select/create a package/module) before previewing or creating
2. Include package in the API payload: {"package":"myapp", ...}
3. Check that frontend form binding actually maps the package input into the request object
4. Trim whitespace — an all-whitespace value still fails via other validations; provide a real identifier

Example fix

// before
await createAutoCode({ tableName: 'users', fields })
// after
await createAutoCode({ tableName: 'users', package: 'example', fields })

// client-side, before calling preview/create
if (!req.package || !String(req.package).trim()) {
  throw new Error('package is required for code generation')
}

function hasPackage(r) {
  return typeof r?.package === 'string' && r.package.trim().length > 0
}

try {
  await createAutoCode(req)
} catch (e) {
  if (String(e.message).includes('Package为空')) {
    formRef.value.validateField('package') // highlight the missing field
  } else { throw e }
}

When it happens

Trigger: Calling Preview or Create with AutoCodeGenReq.Package == "" — e.g. the frontend form never filled the package (module) field, or the field was lost when constructing the request programmatically.

Common situations: Hand-built JSON payloads for the code generator omitting `package`; form submit with module/package select left empty; automated scripts calling the autocode API directly; template/config migration dropping the package field.

Understand the failure class

Background: "Missing required field" and "field is required" errors: why libraries reject payloads that omit mandatory fields — this error's family across 20 libraries.
