Problem using ArrayReferenceField with djongo and django












1














I'am trying to create an application with django using djongo to communicate with mongodb. I have the following model:



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


But when I use django admin to create a new entry here is the error that I get:




TypeError at /admin/app/entry/add/ int() argument must be a string, a
bytes-like object or a number, not 'set' Request Method: POST Request

Please how can I resolve this.
