模块 %d 的 abbreviation 不能为空

Error message

模块 %d 的 abbreviation 不能为空

What it means

Each module in an execution plan must provide an Abbreviation (short name used for generated route prefixes, API paths, and variable names). validateExecutionPlan rejects the plan with this error when modules[i].abbreviation is empty. It runs inside Handle before generation begins.

Solutions

1. Add a short lowercase abbreviation (e.g. "art" for article) to the module entry
2. Keep it URL/router friendly since it feeds generated path prefixes
3. Re-run gva_execute with the corrected plan

Example fix

// before
{"modules":[{"packageName":"article","structName":"Article","tableName":"article","description":"article management"}]}
// after
{"modules":[{"packageName":"article","structName":"Article","tableName":"article","description":"article management","abbreviation":"art"}]}

for i, m := range plan.Modules {
  if m.Abbreviation == "" {
    return fmt.Errorf("modules[%d].abbreviation is required", i)
  }
}

func hasAbbreviation(m Module) bool { return m.Abbreviation != "" }

When it happens

Trigger: Calling gva_execute with a plan where modules[i].abbreviation is missing or "". Typically the Nth validation failure after earlier required fields were filled in.

Common situations: Plans authored by models unaware that abbreviation is mandatory; users who thought abbreviation was an optional alias; templates that omit it for single-module plans.

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.
