我在django中創建模型。這是我在模型文件中的配置。我想創建一個引用縣和公民的表governmentoffical。但是,當我運行manage.py sqlal時,它在政府官方表格中更改了我的專欄名稱。django模型外鍵創建索引

class counties(models.Model): 
    name = models.CharField(max_length=50, primary_key=True, unique=True) 
    population = models.IntegerField() 
    governer = models.CharField(max_length=75) 

class citizen(models.Model): 
    ssn = models.CharField(max_length=40, primary_key=True) 
    citizen_name = models.CharField(max_length=50, unique=True) 
    age = models.IntegerField() 
    income = models.IntegerField() 
    username = models.CharField(max_length=30) 
    password = models.CharField(max_length=30) 

class governmentOfficial(models.Model): 
    countyName = models.ForeignKey(counties, primary_key=True) 
    offical_name = models.ForeignKey(citizen, to_field='citizen_name') 
    position = models.CharField(max_length=50) 
    year_elected = models.IntegerField(max_length=4) 
    party = models.CharField(max_length=25) 
    county_username=models.CharField(max_length=20) 
    county_password=models.CharField(max_length=20) 

這是我的sql輸出。

CREATE TABLE `troywebsite_governmentofficial` (
    `countyName_id` varchar(50) NOT NULL PRIMARY KEY, 
    `offical_name_id` varchar(50) NOT NULL, 
    `position` varchar(50) NOT NULL, 
    `year_elected` integer NOT NULL, 
    `party` varchar(25) NOT NULL, 
    `county_username` varchar(20) NOT NULL, 
    `county_password` varchar(20) NOT NULL 
) 
; 
ALTER TABLE `troywebsite_governmentofficial` ADD CONSTRAINT `countyName_id_refs_name_2c9a2c94` FOREIGN KEY (`countyName_id`) REFERENCES `troywebsite_counties` (`name`); 
ALTER TABLE `troywebsite_governmentofficial` ADD CONSTRAINT `offical_name_id_refs_citizen_name_6f795c2a` FOREIGN KEY (`offical_name_id`) REFERENCES `troywebsite_citizen` (`citizen_name`); 

CREATE INDEX `troywebsite_governmentofficial_effdd6a5` ON `troywebsite_governmentofficial` (`offical_name_id`); 
CREATE INDEX `troywebsite_solider_c5b4e228` ON `troywebsite_solider` (`solider_name_id`); 

有沒有辦法拿出在governmentofficial的CREATE INDEX,並留下來是countyNameOfficial_name爲列?

有什麼特別的原因,你想要的ID列不像ID列? –

沒有特別的原因。我只是想知道爲什麼Django正在改變列的名稱。 – user1817081

[因爲它就是這樣](https://docs.djangoproject.com/en/dev/ref/models/fields/#database-representation),因爲列名對代碼無關緊要。 –
