[{'id': 1, 'code': 'class_land_type', 'parent_code': 'root', 'name': '地类', 'seq': 0, 'dict_type': 'class_info'}, {'id': 37, 'code': 'forest_type', 'parent_code': 'root', 'name': '林种', 'seq': 0, 'dict_type': 'class_info'}, {'id': 64, 'code': 'forest_right', 'parent_code': 'root', 'name': '权属', 'seq': 0, 'dict_type': 'class_info'}, {'id': 68, 'code': 'terrain', 'parent_code': 'root', 'name': '地形', 'seq': 0, 'dict_type': 'class_info'}, {'id': 75, 'code': 'slope_position', 'parent_code': 'root', 'name': '坡位', 'seq': 0, 'dict_type': 'class_info'}, {'id': 82, 'code': 'slope_direction', 'parent_code': 'root', 'name': '坡向', 'seq': 0, 'dict_type': 'class_info'}, {'id': 84, 'code': 'soil_type', 'parent_code': 'root', 'name': '土壤类型', 'seq': 0, 'dict_type': 'class_info'}, {'id': 86, 'code': 'forest_protect_level', 'parent_code': 'root', 'name': '林地保护等级', 'seq': 0, 'dict_type': 'class_info'}, {'id': 91, 'code': 'domaint_tree_type', 'parent_code': 'root', 'name': '优势树种', 'seq': 0, 'dict_type': 'class_info'}, {'id': 117, 'code': 'origin', 'parent_code': 'root', 'name': '起源', 'seq': 0, 'dict_type': 'class_info'}, {'id': 124, 'code': 'age', 'parent_code': 'root', 'name': '龄组', 'seq': 0, 'dict_type': 'class_info'}]
另外：
res = Sysdict.query.all() 这种写法已经不被推荐了，
推荐的是scalar_one() 获取一行，scalars()获取多行
user = db.session.execute(db.select(User).filter_by(username=username)).scalar_one()
users = db.session.execute(db.select(User).order_by(User.username)).scalars()
一般的
json.dumps(users)
或者
jsonify(users)
都会出现错误：Object of type ScalarResult is not JSON serializable
所以，使用这两个方法解决：
def model_to_dict(object):
return {c.name: getattr(object, c.name) for c in object.table.columns}
#将一组数据转为list
def scalars_to_list(object):
return [model_to_dict© for c in object]
