如何将 Django class 名称引用到函数中？

Question

我写了一个函数，returns 在 Django 中为一个 class 插入字符串，在 FileMaker 中建模和映射 table。

@staticmethod
def get_insert_string():
    fields = []
    arguments = []
    for field in Owner._meta.fields:
        if field.primary_key:
            pass
        elif field.help_text:
            fields.append('"%s"' % field.help_text)
            arguments.append('?')
    result = 'insert into %s ( %s ) values ( %s )' % ( Owner.filemaker_table_name, u','.join(fields), u','.join(arguments)) 
    return result

示例输出。

Owner.get_insert_string()

u'插入所有者 ( "uuid","ABN_number","Address_1","Creation_Date","Creation_Time","Creation_User","Creation_timestamp","Date_started","Modification_timestamp","State","Suburb","account_code","account_name","account_number","authorised_officer_first_name" ,"authorised_officer_signature","authorised_officer_surname","bank_name","bsb","company_name","company_use_as_address","crn_number","discount_percent","driver_or_staff","fax","is_driver","is_staff","jp_name","jp_number","jp_signature","landline","mobile","oa_number","owner_1_first_name","owner_1_middle_name","owner_1_surname","owner_2_first_name","owner_2_middle_name","owner_2_surname","owner_3_first_name" ,"owner_3_middle_name","owner_3_surname","paid_always","parts_at_cost","post code","purchase_order_required","shareholder","status","taxable","taxable_export","thirty_day_account","trade_retail_for_parts_cost","tsl_number","tsl_owner","updated_date" ) 值 ( ?,?,?,? ,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,? ,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,? ,?)'

如何更改它以便传入 class 的名称并获得相同的结果，以便该函数可用于模块中的所有 classes？

类似

def get_insert_string(class_name):
    fields = []
    arguments = []
    for field in class_name._meta.fields:
        if field.primary_key:
            pass
        if field.help_text:
            fields.append('"%s"' % field.help_text)
            arguments.append('?')
    result = 'insert into %s ( %s ) values ( %s )' % ( class_name.filemaker_table_name, u','.join(fields), u','.join(arguments)) 
    return result

其中 class_name 映射到匹配的 Django class。

发现的 globals() 大部分涵盖了它。

函数示例。

def get_insert_string(class_reference):
    fields = []
    arguments = []
    for field in class_reference._meta.fields:
        if field.primary_key:
            pass
        elif field.help_text:
            fields.append('"%s"' % field.help_text)
            arguments.append('?')
    result = 'insert into %s ( %s ) values ( %s )' % ( class_reference.filemaker_table_name, u','.join(fields), u','.join(arguments)) 
    return result

调用示例：

depot_maestro.models.get_insert_string(globals()['DriverShiftPreference'])

结果示例：

insert into driver_shift_preferences ( "DEPOT_ID","driver_id","roster_template_id","roster_template____shift_slot_id","vehicle_id","uuid","commission_percentage","drive_name_lookup","lease_fee","levy_1","levy_2","linked_to_id","note","selected","shift_slot","week_id","creation_account_name","created_timestamp","modification_account_name","modification_timestamp" ) values ( ?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,? )'

唯一剩下的问题是如何引用 class，其中相同的 class 名称存在于不同的模块中。
