嵌入文档 MongoEngine 允许你将一个文档嵌入到另一个文档中 from mongoengine import EmbeddedDocument, EmbeddedDocumentField, ListField...max_length=100) class User(Document): name = StringField(required=True, max_length=200) addresses = ListField
name = db.StringField(required=True) code = db.StringField(required=True) type = db.ListField...(db.EmbeddedDocumentField('ImgType')) params = db.ListField(db.EmbeddedDocumentField('ImgParam')...Document): type = StringField(required=True) name = StringField(required=True) value = ListField

执行测试 listField方法赋值成功。...也可以连续调用listField赋值多个元素到列表中 执行测试 说明连续调用赋值也是成功的 查看target目录下生成的class代码 listField方法可以接收一个单独的String
ImageField ImageField(max_length=None, allow_empty_file=False, use_url=UPLOADED_FILES_USE_URL) ListField...ListField(child=, min_length=None, max_length=None) DictField DictField(child=) 常用的有： CharField...IntegerField FloatField DecimalField DateTimeField DateField 注意： ''' ListField和DictField原来的...models是没有的，主要用来做反序列,处理前端传入的数据 ''' 比如我们从前端接收json格式数据 "hobby":["篮球","足球"] 可以用ListField处理 "wife":{"name"...models中处理完返回给序列化类中继续当成字段处理了 注意: 如果是返回的是这种格式的数据，需要那么序列化类中就不能指定CharField类型，这样会直接返回字符串类型，不方便后期的处理，需要指定成ListField

它的语法如下: WHERE item %INLIST listfield %INLIST使用EXACT排序。 因此，默认情况下，%INLIST字符串比较是区分大小写的。
%INLIST listfield - 将字段值与%List结构化列表中的任何元素匹配的相等条件。 [ - 包含运算符。 Match必须包含指定的字符串。
