保存文章时django不添加自动递增主键id

Question

我在 django 管理站点安装了一个文章应用程序，当我完成一篇文章的编辑后，我点击了保存按钮，但是出现了一个错误页面：

article/models.py

# blog category models
class Category(models.Model):
    id = models.IntegerField(primary_key=True,help_text='primary key')
    name = models.CharField(max_length=50,help_text='category name')
    description = models.TextField(default='',help_text='category description')
    createtime = models.DateTimeField(auto_now_add=True)
    modifytime = models.DateTimeField(auto_now=True)

    categories = models.Manager()

    class Meta:
        db_table = 'article_category'
    def __str__(self):
        return self.name

#blog article models
class Article(models.Model):
    STATUS = (
        (0,'on'),
        (1,'off')
    )
    id = models.IntegerField(primary_key=True,help_text='primary key')
    category = models.ForeignKey(Category,help_text='foreigner key reference Category')
    title = models.CharField(max_length=100,help_text='article title')
    content = models.TextField(help_text='article content')
    like = models.IntegerField(default=0,help_text='like numbers')
    secretcode = models.CharField(max_length=512,help_text='who has the code can scan')
    status = models.IntegerField(choices=STATUS,help_text='status of the article')
    createtime = models.DateTimeField(auto_now_add=True,help_text='time that first created')
    modifytime = models.DateTimeField(auto_now=True,help_text='time when modified')

    articles = models.Manager()
    class Meta:
        db_table = 'article'

article/widgets.py

from pagedown.widgets import AdminPagedownWidget
from django import forms
from .models import Article

class ArticleModelForm(forms.ModelForm):
    content = forms.CharField(widget=AdminPagedownWidget())
    class Meta:
        model = Article
        fields = ('title','category', 'content', 'secretcode', 'status')

article/admin.py

from django.contrib import admin
from .widgets import ArticleModelForm
from .models import Article,ArticleImage,Category

class  MMBArticleAdmin(admin.ModelAdmin):
    form = ArticleModelForm

admin.site.register(Article,MMBArticleAdmin)
admin.site.register(Category)
admin.site.register(ArticleImage)

管理站点中的页面如下所示：

然后我点击保存，错误页面如上所示！为什么会这样？如何解决？

您已使用手动非自动递增 ID 覆盖默认自动字段。不要那样做。完全删除您的 id 个字段。
