Hi, All the information I need, I can get in 1 SQL query with this query and model:
categories=Article.query.filter(Article.parent == None).all() class Article(DefaultEntity): name = Field(Unicode(64), index=True) parent = ManyToOne('Article') children = OneToMany('Article', lazy=False, join_depth=4) But I don't want to lazy load all children all the time. So I try to get this query and model working, and still get the data in 1 SQL query: categories=Article.query.options(eagerload('children')).filter (Article.parent == None).all() class Article(DefaultEntity): name = Field(Unicode(64), index=True) children = OneToMany('Article') I think I need to specify a join_depth along with the eagerload option, but according to the documentation, there's no such option.
