 来源:mongoosejs 浏览 290 扫码 分享 2021-02-07 09:13:21
  • Document.prototype.markModified()
    • Parameters
  • Example:

    Document.prototype.markModified()

    Parameters

    • path «String» the path to mark modified

    • [scope] «Document» the scope to run validators with

    Marks the path as having pending changes to write to the db.

    Very helpful when using Mixed types.

    Example:

    1. doc.mixed.type = 'changed';
    2. doc.markModified('mixed.type');
    3. doc.save() // changes to mixed.type are now persisted
