django模型外键创建索引

我在django中创建模型。这是我在模型文件中的配置。我想创建一个引用县和公民的表governmentoffical。但是，当我运行manage.py sqlal时，它在政府官方表格中更改了我的专栏名称。django模型外键创建索引

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)

这是我的sql输出。

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`);

有没有办法拿出在governmentofficial的CREATE INDEX，并留下来是countyName和Official_name为列？

有什么特别的原因，你想要的ID列不像ID列？ –

没有特别的原因。我只是想知道为什么Django正在改变列的名称。 – user1817081

[因为它就是这样]（https://docs.djangoproject.com/en/dev/ref/models/fields/#database-representation），因为列名对代码无关紧要。 –
