Question

我正在尝试在模型中创建一个ManyToManyField，数据库中的表连接到数据库中的视图。

连接到视图的模型（名为precheck_check）已成功迁移，因此唯一的新代码为applicable_checks = models.ManyToManyFields(Check, related_name = '+')。

当我尝试使用添加的代码进行迁移时，我得到django.db.utils.ProgrammingError: referenced relation "precheck_check" is not a table"

Models.py 来自 future 导入unicode_literals

from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
from django.core.validators import validate_slug,validate_comma_separated_integer_list
from static import validators


class Check(models.Model):
    pkey = models.IntegerField(primary_key=True)
    cif = models.CharField(max_length=255)
    check_name = models.CharField(max_length=255)
    description = models.TextField()

    class Meta:
        managed = False

# Create your models here.
class Job(models.Model):
    user = models.ForeignKey('auth.User')
    jobID = models.CharField(max_length=50, validators=[validate_slug])
    original_file = models.FileField(upload_to='temp',validators = [validators.validate_zip])
    rev = models.IntegerField()
    create_date = models.DateTimeField(default=timezone.now)
    file_name = models.CharField(max_length=255, null = True)
    applicable_checks = models.ManyToManyField(Check, related_name = '+')


    def save(self):
        last_rev = Job.objects.filter(user_id=self.user_id).filter(jobID=self.jobID).order_by('-rev')
        if last_rev:
            self.rev = last_rev[0].rev + 1
        else:
            self.rev = 1
        super(Job,self).save()

    def __unicode__(self):
        return self.jobID + " rev " + str(self.rev)

    class Meta:
        indexes = [
            models.Index(fields=['user','jobID']),
        ]
        unique_together = ("user","jobID","rev")
        ordering = ['-create_date']
        get_latest_by = 'create_date'

我哪里错了？

使用postgresql视图的Django manytomany字段
