我正在尝试创建一个表单并将其数据存储在我创建模型的数据库中，但它也显示错误。模型.py

from django.db import models
from django.contrib.auth.models import User

class SellForm(models.Model):
    FICTION = 'fiction'
    Course = 'course'
    Non_Fiction = 'nonfic'
    book_category = [
        (FICTION, 'Fiction'),
        (Course, 'Course'),
        (Non_Fiction, 'Non fiction'),
    ]
    NEW = 'new'
    OLD = 'old'
    book_condition =[
        (NEW,'new'),
        (OLD, 'old'),
    ]
    ENGLISH = 'eng'
    HINDI = 'Hindi'
    book_lang =[
        (ENGLISH,'english'),
    (HINDI,'hindi'),
    ]

    title = models.CharField(max_length=100)
    author = models.CharField(max_length=100)
    price = models.IntegerField()
    Category = models.CharField(max_length=20,choices=book_category,default=Course,)
    Condition = models.CharField(max_length=20,choices=book_condition,default=OLD)
    Language = models.CharField(max_length=20,choices=book_lang,default=HINDI)
    Description =models.CharField(max_length=200)
    book_img = models.ImageField(upload_to='images/')
    user = models.ForeignKey(User, on_delete=models.CASCADE)

表格.py

from django import forms
from .models import SellForm

class FromSellForm(forms.ModelForm):
    class Meta:
        model = SellForm
        fields = ["title","author","price","Category","Condition","Language","Description","book_img"]

视图.py

from django.shortcuts import render,redirect
from django.http import HttpResponse
from .forms import FromSellForm

# Create your views here.
def sell_book(request):
    if request.method == 'POST':
        form = FromSellForm(request.POST,request.FILES)
        if form.is_valid():
            form.save()
            return redirect('home')
    else:
        form = FromSellForm()
    context = {'form':form}
    return render(request,'buy/sellbook.html',context)

卖书.html

<form method = "post" enctype="multipart/form-data"> 
            {% csrf_token %} 
            {{ form.as_p }} 
            <button type="submit">Upload</button> 
        </form> 

销售应用程序的 urls.py

from django.urls import path

from . import views

urlpatterns = [
    path('sell_book/', views.sell_book,name="sell_book"),
]

Exception Type: ProgrammingError at /sell/sell_book/
Exception Value: (1146, "Table 'buysell.sell_sellform' doesn't exist")

而且由于我还想使用表单上传图像，因此我在 settings.py 和 urls.py 的根目录中添加了所需的代码。我已经运行了 makemigrations 和 migrate 命令，但我也收到错误消息（1146，“表 'buysell.sell_sellform' 不存在”）。请告诉错误。提前致谢。
