非常感谢您的帮助。如果您的收藏未定义,则会发生此错误 一种可能的修复方法是将集合设置为全局,如下所示:
global.Settings = Settings; // try this instead of window
否则,您只需更改模板将集合返回表单的方式即可:
{{> quickForm collection=Settings id=_id type="update" doc=this}}
现在,它使用帮助器显式接收集合,而不是查看全局范围,因为您已经定义了此帮助器:
Settings() {
return Settings;
}
如果这仍然不起作用,请检查集合是否通过给定的路径正确导入(例如,尝试不要以
/imports
开头,而是以当前目录开头)。此问题是否仍然存在问题?
