Requirement

Python 3.x(suggest 3.8.10+)

Feature & Function:

Newest

V1.9.0

1. more table select (One to One)
2. update cache for supporting more table
3. value of main field & sub field transfer to where condition
4. more table select support condition
5. more table select support paging
6. more table select (One to Many)
7. more table select (Many to One)
8. more table select support paging with params
9. create table support joins anno

V1.0

1.The framework uses a unified API to operate the database;
2.Single table query, modification, addition, and deletion (SUID);
3.Developers only need to focus on the use of the SUID API, which is an object-oriented approach to the framework;
4.The entity class corresponding to the table can only use ordinary entity classes, without the need to add additional table structure information and framework related information;
5.You can specify which database to use based on the configuration information.
6.Support anti SQL injection;
7.Support native SQL;
8.The framework is responsible for managing the implementation logic of connections, transaction commit, rollback, etc;
9.The encoding complexity C (n) of ORM is O (1).

V1.1

1. SQL keywords, supporting capitalization;
2. Batch insert: Batch insert;
3. Reuse the connection to improve efficiency;
4. Add system definition exceptions

V1.3

is_sql_key_word_upper can set upper/lower in configure
Print log level characters
Improve log output
Add PreConfig to specify the location of the configuration file
Improve anomalies

V1.5

1.5.2

1. add Version
2. adjust naming
   (uploaded the stability function before)

1.5.4(2025·Valentine's Day·LTS)
3. adjust exception and select_paging 4. add PreparedSql support custom SQL
5. update toUpdateSQL function
6. select_by_id
7. delete_by_id
8. select_fun
9. count
10. exist
11. create_table
12. index_normal
13. unique

1.6.0(2025·International Labour Day)

1. Optimize BeeSql
2. enhance the code
3. Add naming conversion support
4. add interceptors
5. can print execute min time
   can config the print execute min time
6. adjust select_by_id,delete_by_id def select_by_id(self, entity_class, *ids)
   def delete_by_id(self, entity_class, *ids)
7. Preconfig.config.path is used to set the path where the configuration file/SQLite database file is located
8. Support complex where statement constructor Condition
   e.g. name!='aaa',age>=10, like, between,group by,having,order,paging(start,size)
9. Support Update Set to set the expression constructor Condition for updates
10. Select query supports specifying the fields to be queried
11. transform the Result of the query
12. Convert the type of setting parameters
13. support cache
    support md5 for cache key
14. transform bool result
15. enhance config
16. support python version 3.8.10+
17. generate bean/entity file
18. bean/entity mid type support
19. cache entity field_and_type
20. Object oriented approach, when creating a table, supports declaring fields with unique constraints in entities and fields that are not allowed to be empty:
    unique_key={"name","type"}
    not_null_filels={"name","type"}

1.6.2(2025.08)

1. support condition like/like_left/like_right,in/not in;
   eg: condtion.op("num", Op.IN, [1,2]); can support list/set/tuple type
2. update cache config:cache_never,cache_forever,cache_modify_syn config
3. enhance paging(LimitOffset)
4. update default naming type(use OriginalName)
5. update condition Expression
6. support active record style
7. use SQL keywords for compatible field name or table name

1.6.8(2025.08)

1. enhance the code
2. fixed bug
   SuidRich:updateBy,
   Condition:orderBy2,orderBy2,
   HoneyConfig.set_db_config_dict

Quick Start:

Installation

To install, type:

pip install ormbee

ORM Bee pypi url:
https://pypi.org/project/ormbee/

1. set db config

1.1.can custom your db Module

in bee.json or bee.properties set dbModuleName

 {
 "dbname": "SQLite",  
 "database": "bee.db", 
 //default support: pymysql,sqlite3,cx_Oracle,psycopg2 (no need set)
 "dbModuleName":"sqlite3"
 }

#value is: MySql,SQLite,Oracle,
#MySQL config
#bee.db.dbname=MySQL
#bee.db.host =localhost
#bee.db.user =root
#bee.db.password =
#bee.db.database =bee
#bee.db.port=3306

# SQLite
bee.db.dbname=SQLite
bee.db.database =bee.db

1.2.if do not want to use the default config file(bee.json or bee.properties),

can set the db_config info yourself.

        # #mysql
        dict_config = {  
            'dbname':'MySQL',
            'host': 'localhost',
            'user': 'root',
            'password': '',
            'database': 'bee',
            'port':3306
        }
        
        honeyConfig= HoneyConfig()
        honeyConfig.set_db_config_dict(dict_config)

1.3.set connection directly:

        config = {  
            # 'dbname':'MySQL',
            'host': 'localhost',
            'user': 'root',
            'password': '',
            'database': 'bee',
            'port':3306
        }
        
        honeyConfig= HoneyConfig()
        honeyConfig.set_dbname("MySQL")
        
        conn = pymysql.connect(**config)
        factory=BeeFactory()
        factory.set_connection(conn)
        

2. operate DB with Bee

class Orders:
    id = None  
    name = None 
    remark = None

    # can ignore
    def __repr__(self): 
        return  str(self.__dict__)

  
# also can use field type as :int        
class Orders8:
    __tablename__ = "orders"
    id:int = None  
    name:str = None 
    remark:str = None

    def __repr__(self): 
        return  str(self.__dict__)

    id = None
    name = None 
    age = None  
    remark = None
    addr = None

    def __repr__(self): 
        return  str(self.__dict__)

    orderList = suid.select(Orders())  # select all
    
    # insert    
    orders = Orders()
    orders.id = 1
    orders.name = "bee"
    orders.remark = "test"
    
    suid = Suid()
    suid.insert(orders)
    
    # update/delete
    orders = Orders()
    orders.name = "bee130"
    # For safety reasons
    # Fields that are not present in the entity will be ignored.
    orders.ext = "aaa"  
    orders.id = 1
    
    suid = Suid()
    n1 = suid.update(orders)
    n2 = suid.delete(orders)
    print(n1)
    print(n2)
    
    # batch insert
    student0 = Student2()
    student0.name = "bee"
    student1 = Student2()
    student1.name = "bee1"
    student1.addr = ""
    student1.age = 40
    entity_list = []
    entity_list.append(student0)
    entity_list.append(student1)
    
    suidRich = SuidRich()
    insertNum = suidRich.insert_batch(entity_list)
    print(insertNum)
    
    #how to use Condition for advanced query and update
    condition = BF.condition()
    condition.op("age", Op.ge, 22)
    condition.op("remark", Op.eq, None)
    stuList = suidRich.select(Student2(), condition)
    # select ... from student2 where age >= ? and remark is null
    for stu in stuList:
        print(stu)
    
    # all stu'age add 1 if id>5
    condition = BF.condition()
    condition.setAdd("age", 1)
    condition.op("id", Op.ge, 5)
    updateNum = suidRich.updateBy(Student2(), condition)
    # update student2 set age = age + ? where id >= ?
    print("updateNum:", updateNum)
    
    # SuidRich: insert_batch,select_first,updateBy
    # complex where statement constructor Condition
