Error when adding an ArrayModelField to models.

Following djongo tutorial: https://djongo.readthedocs.io/docs/array-model-field/

Using:

• Django==2.2.12
• djongo==1.3.2

Python script

in models.py django project

 from djongo import models

 class succesfull_injections(models.Model):
      sqli = models.CharField(max_length=100)

      class Meta: 
          abstract = True

  class attack(models.Model):
      succesfullInjections = models.ArrayModelField(
              model_container = succesfull_injections,
              )
      successSQLI = models.CharField(max_length=100)
      time = models.CharField(max_length = 100)
        triedInjections = models.CharField(max_length = 100)

Solved this one, the documentation in this link is mistaken.

The problem is that it is not ArrayModelField but only ArrayField

class attack(models.Model):
      succesfullInjections = models.ArrayModelField(
              model_container = succesfull_injections,
              )
      successSQLI = models.CharField(max_length=100)
      time = models.CharField(max_length = 100)
        triedInjections = models.CharField(max_length = 100)

The correct would be:

class attack(models.Model):
      succesfullInjections = models.ArrayField(
              model_container = succesfull_injections,
              )
      successSQLI = models.CharField(max_length=100)
      time = models.CharField(max_length = 100)
        triedInjections = models.CharField(max_length = 100)

@nesdis I think this link may be deprecated.

Now I'm having the following issue #417

@Jagl257 I think you are right. I realised one more issue while trying to make ArrayField work. If your succesfull_injections has only 1 attribute you won't get any errors what so ever with ArrayField. However, If you have multiple attributes/objects inside of succesful_injection you'll get the same error as #417 @nesdis

Hey @Jagl257, solved this issue here

[Invincible166]

Its strange. Actually I am getting this error

AttributeError: module 'djongo.models' has no attribute 'ArrayField'

However with ArrayModelField I get a different error.

TypeError at /speechAPI/ isinstance() arg 2 must be a type or tuple of types

Here is my code if anyone could help.

from appconf import AppConf
from djongo import models
from django import forms

class Words(models.Model):
    duration = models.DurationField() 
    offset = models.TimeField() 

    class Meta:
        abstract = True

class WordsForm(forms.ModelForm):
    class Meta:
        model = Words
        fields = ('duration', 'offset')

class Transcript(models.Model):
    display_text = models.TextField()
    words = models.ArrayModelField(model_container=Words,model_form_class=WordsForm)

    class Meta:
        abstract = True

class Transcription(models.Model):
    request_id = models.CharField(max_length=100)
    q_id = models.BigIntegerField()
    source = models.CharField(max_length=100)
    transcript = models.EmbeddedModelField(model_container=Transcript)

    objects = models.DjongoManager()

Any insight into the error would be greatly appreciated.

[amit-jha-cmd]

Can you mention the version of Djongo and Django you are on?

[Invincible166]

Django==2.2.12 Djongo==1.2.38

[Invincible166]

I have now upgraded djongo to 1.3.2. Now whenever I try to use

models.EmbeddedField(model_container=Transcript)

It gives the following error:

raise AppRegistryNotReady("Models aren't loaded yet.") django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet.

Hi @Invincible166 I'm having the same issue. See #417
