我正在尝试使用 djongo 创建一个带有 django 的应用程序来与 mongodb 进行通信。我有以下模型:

from djongo import models
from django import forms

class Blog(models.Model):
    name = models.CharField(max_length=100)
    tagline = models.TextField()

    class Meta:
        abstract = True

class BlogForm(forms.ModelForm):
    class Meta:
        model = Blog
        fields = (
            '__all__'
        )

class MetaData(models.Model):
    # pub_date = models.DateField()
    # mod_date = models.DateField()
    n_pingbacks = models.CharField(max_length=255)
    rating = models.CharField(max_length=255)

    class Meta:
        abstract = True

class MetaDataForm(forms.ModelForm):
    class Meta:
        model = MetaData
        fields = (
            '__all__'
        )

class Author(models.Model):
    name = models.CharField(max_length=200)
    email = models.EmailField()

    def __str__(self):
        return self.name

class AuthorForm(forms.ModelForm):
    class Meta:
        model = Author
        fields = (
            'name', 'email'
        )

class Entry(models.Model):
    blog = models.EmbeddedModelField(
        model_container=Blog,
        model_form_class=BlogForm
    )
    meta_data = models.EmbeddedModelField(
        model_container=MetaData,
        model_form_class=MetaDataForm
    )

    headline = models.CharField(max_length=255)
    body_text = models.TextField()

    authors = models.ArrayReferenceField(
        to=Author,
        on_delete=models.CASCADE,
    )
    n_comments = models.CharField(max_length=255)

    def __str__(self):
        return self.headline

但是当我使用 django admin 创建一个新条目时,我得到的错误是:

/admin/app/entry/add/ int() 参数的 TypeError 必须是字符串、类似字节的对象或数字,而不是“设置”请求方法:POST 请求 URL: http://localhost:8000/admin/ app/entry/add/ Django 版本:2.1.3 异常类型:TypeError 异常值:int() 参数必须是字符串、类似字节的对象或数字,而不是“设置”异常位置:C:\Users\scg \Documents\Rest_project\envschool\lib\site-packages\django\db\models\fields__init__.py 在 get_prep_value,第 965 行 Python 可执行文件:C:\Users\scg\Documents\Rest_project\envschool\Scripts\python.exe Python 版本:3.7.1 Python 路径:

请问我该如何解决这个问题。

我正在使用 django 2.1.3 和 djongo 1.2.30

我遇到了类似的问题。我通过降级到 Django 2.0 解决了这个问题。
