插件初始化文件缺少 []model.%s 数组

Error message

插件初始化文件缺少 []model.%s 数组

What it means

The initialize file parsed successfully, but ast.FindArray found no []model.<Selector> array (e.g. []model.SysMenu) with the expected selector name, so loadPluginInitializeArray returns errors.Errorf '插件初始化文件缺少 []model.%s 数组'.

Solutions

1. Ensure the initialize file declares the array as []model.SysMenu{...} (matching the expected selector)
2. Regenerate the plugin initialize files with the current code generator version
3. Compare with a freshly generated plugin's initialize file and align the structure
4. Check you are initializing the correct plugin name
5. If the array is intentionally empty, keep the declaration (an empty literal is fine) rather than deleting it

Example fix

// before: wrong element type
var menus = []sysModel.Menu{...}
// after
var M = []model.SysMenu{ ... }

// grep for the expected array declaration before init
data, _ := os.ReadFile(path)
varName := "SysMenu" // per init kind
marker := "[]model." + varName + "{"
if !bytes.Contains(data, []byte(marker)) {
    return fmt.Errorf("initialize file lacks %s array", marker)
}

err := pluginSvc.InitDictionary(ctx, pluginName)
if err != nil && strings.Contains(err.Error(), "插件初始化文件缺少 []model.") {
    // regenerate the plugin initialize files with the current generator version
}

When it happens

Trigger: InitMenu/InitAPI/InitDictionary on a plugin whose initialize file is valid Go but does not declare the expected array variable of type []model.X — wrong file, renamed variable, or changed element type.

Common situations: Plugin template version mismatch (older initialize files using a different structure); user renamed the array variable or element type; wrong plugin selected so the file exists but holds a different array; generator produced an empty or commented-out array.
