在我的一个模型中，我试图通过DjangoSQL查询用户在一个模型对象的函数中使用的条目。如何在传记模型中成功地从sql查询到prompt方法对象的journal模型函数？
下面的代码是我正在尝试的，但没有生成任何函数搜索：

from django.db import models
from django.urls import reverse
from django.conf import settings
import misaka
# Create your models here.
from django.contrib.auth import get_user_model
User = get_user_model()
class Biography(models.Model):
    user = models.ForeignKey(User,related_name='biography',on_delete=models.CASCADE)
    created_at = models.DateTimeField(auto_now=True)
    prompt = models.CharField(max_length=256,default="")
    prompt_html = models.CharField(max_length=256,editable=False,default="")
    entry = models.TextField(default="")
    entry_html = models.TextField(editable=False)

class Journal(models.Model):
    def gen_prompt():
        def sort_by_auth_user(self, item):
            if item.created_by == self.request.user:
                return -1
            else:
                return 1
        def get_queryset(self):
            with connection.cursor() as cursor:
                cursor.execute('SELECT entry FROM journal_Biography')
                journal_str = cursor.fetchall()
                sorted_journal_str = sorted(journal_str, key=self.sort_by_auth_user)
                journal_str = str(sorted_journal_str)
                qg = TextGenerator(output_type="question")
                gen_prompt = qg.predict([journal_str])
                return gen_prompt
    user = models.ForeignKey(User,related_name='journal',on_delete=models.CASCADE)
    created_at = models.DateTimeField(auto_now=True)
    prompt = models.CharField(max_length=256,default=gen_prompt())
    prompt_html = models.CharField(max_length=256,editable=False,default=gen_prompt())
    entry = models.TextField(default='')
    entry_html = models.TextField(editable=False)
