在django中创建了模型表单，缺少主键

我在django中创建了一个modelform，但是浏览器中缺少主键字段。它在哪里？我怎样才能让它出现。如果您需要比我下面的代码更多的代码，请告诉我

在阅读了一些内容后，我认为您永远不会，甚至不会意外地，向用户公开一个：

如果你真的想向你的用户公开PK（我不知道你为什么要这样做），你必须在模型和表单上明确地公开PK，否则

ModelForm

会为你排除它：

import autocomplete_light
from django.forms import ModelForm, IntegerField

from error_tracking.models import Incident

autocomplete_light.register(Incident, search_fields=['incident_id'])

class IncidentForm(autocomplete_light.ModelForm):
    class Meta:
        model = Incident
        fields = ['incident_id', 'user_id', 'equipment_id', 'incident_category', 'incident_date_time_reported', 'incident_date_time_occurred', 'description']
    incident_id = IntegerField()

class Incident(models.Model):
       incident_id = models.IntegerField(primary_key=True)
       incident_date_time_reported = models.DateTimeField('incident reported', default=timezone.now)
       user_id = models.ForeignKey(User)
       incident_date_time_occurred = models.DateTimeField('incident occurred', default=timezone.now)
       clinical_sample = models.BooleanField(default=True)
       number_of_clinical_samples = models.IntegerField(default=0)
       sample_id_numbers = models.TextField(max_length=1000)
       equipment_id = models.ForeignKey(Equipment)
       incident_category = models.ForeignKey(Incident_Category)
       technician = models.TextField(max_length=1000)
       description = models.TextField(max_length=1000)
       action_taken = models.TextField(max_length=1000)
       open = models.BooleanField(default=True)

       def __str__(self):
               return self.incident_id

       class Meta:
               verbose_name_plural="Incident"

---

如果浏览器中缺少它，请显示您的HTML模板和相应的视图。就是这样。我想自动为事件分配一个id，并希望用户稍后在搜索中使用该id。这有意义吗？有没有比公开pk更好的方法？
