[filpath:%s]生成文件失败!

Error message

[filpath:%s]生成文件失败!

What it means

After a template parses successfully, generate executes it against the request.AutoCode data; an execution error is wrapped as '[filpath:%s]生成文件失败!'. This means the template body itself failed while rendering (missing method/field on data, index out of range, custom template function error), not that the file is unreadable.

Solutions

1. Read the wrapped cause printed with the error — it names the exact template line/executing action; fix that line in the .tpl.
2. Check any custom template functions used exist in autocode.GetTemplateFuncMap and support the input type (e.g. DB column type mapping) for your field definitions.
3. If this started after an upgrade, diff your custom .tpl files against the version-matched official templates and update accesses to renamed AutoCode fields.

Example fix

{{/* before: assumes field exists */}}
{{ .TableName .StructName }}
{{/* after: guard */}}
{{ if .StructName }}{{ .TableName .StructName }}{{ end }}

out, _, _, err := svc.generate(info, templates, asts)
if err != nil {
  if strings.Contains(err.Error(), "生成文件失败") {
    // parse wrapped template exec error to locate the failing tpl
    log.Printf("template execution failed, check recent .tpl edits: %v", err)
  }
  return err
}

When it happens

Trigger: files.Execute(&builder, info) fails during Create or Preview when: the .tpl calls a field/method absent from request.AutoCode, a template func from GetTemplateFuncMap errors (e.g. unmapped DB type), or data assumptions break (nil maps/slices indexed by the template).

Common situations: Custom templates written against an older AutoCode struct after upgrading; unsupported database column type passed into a type-mapping template function; template assumes a non-empty collection the request does not provide.
