1054，django 中的“字段列表”中的“未知列 'work_waterlevel.id'”

Question

I am trying to display my mysql data on a HTML page everything is working fine but when i try to display the data from mySQL tohtml page its showing 1054, "Unknown column 'work_waterlevel.id' in 'field list'") this error how要解決此錯誤，我的 models.py 是

from django.db import models

# Create your models here.
class waterlevel(models.Model):
    time=models.DateTimeField()
    status=models.CharField(max_length=50)
    level=models.DecimalField(max_digits=12,decimal_places=6) 

回溯如下

 File "C:\Users\siddhant\AppData\Local\Programs\Python\Python39\lib\site-packages\django\db\backends\utils.py", line 84, in _execute
    return self.cursor.execute(sql, params)
  File "C:\Users\siddhant\AppData\Local\Programs\Python\Python39\lib\site-packages\django\db\backends\mysql\base.py", line 73, in execute
    return self.cursor.execute(query, args)
  File "C:\Users\siddhant\AppData\Local\Programs\Python\Python39\lib\site-packages\MySQLdb\cursors.py", line 206, in execute
    res = self._query(query)
  File "C:\Users\siddhant\AppData\Local\Programs\Python\Python39\lib\site-packages\MySQLdb\cursors.py", line 319, in _query
    db.query(q)
  File "C:\Users\siddhant\AppData\Local\Programs\Python\Python39\lib\site-packages\MySQLdb\connections.py", line 259, in query
    _mysql.connection.query(self, query)
MySQLdb._exceptions.OperationalError: (1054, "Unknown column 'work_waterlevel.id' in 'field list'")

它顯示我的 view.py 文件中有錯誤我的 view.py 文件如下

def generate(request):
    
    b=request.POST['level']
    a=request.POST['status']
    output=run([sys.executable,'C:\\Users\\siddhant\\Desktop\\internship\\indicator\\work\\water.py',b,a],stdout=PIPE,text=True)
    event_list=waterlevel.objects.all()
    
    return render(request,'result.html',{'event':event_list})

任何人都可以建議我如何將我的 MySQL 數據發送到 result.html 頁面
