Creating ModelForm with EmbeddedModelField and customize fields within EmbeddedModelField - django

Question

I have a model (parentmodel) which is having a EmbeddedModelField (embedmodel). This is basically a document in MongoDB. Below is the Model classes
class embedmodel(models.Model):
sendto = models.CharField(max_length=10)
sendtouser = models.CharField(max_length=15)
sendtogroup = models.CharField(max_length=15)
class parentmodel(models.Model):
name = models.CharField(max_length=30, unique=True, primary_key=True)
type = models.CharField(max_length=11)
enabled = models.BooleanField()
rule = models.EmbeddedModelField(model_container=embedmodel)
class Meta:
managed = False
db_table = 'parentmodel'
And this is how my document in mongodb looks like
{
'name': 'rule1',
'type': 'static',
'enabled': True,
'rule': {
'sendto': 'external',
'sendtouser': 'sam',
'sendtogroup': 'vendor'
}
}
I am trying to create a form which helps me create new rules and this is what i have in forms.py where i want to customize the form fields as well.
class RulesForm(forms.ModelForm):
name = forms.CharField(max_length=30, required=True)
type = forms.CharField(max_length=11, required=True)
enabled = forms.BooleanField(widget=forms.CheckboxInput)
class Meta:
model = parentmodel
fields = ['name', 'type', 'enabled', 'rule']
How to do customize the fields being displayed from embedmodel? I tried the below but no luck.
class RulesForm(forms.ModelForm):
name = forms.CharField(max_length=30, required=True)
type = forms.CharField(max_length=11, empty_value="UserDefined", required=True
enabled = forms.BooleanField(widget=forms.CheckboxInput)
sendto = forms.ChoiceField(widget=forms.Select, choices=[(1, 'External'), (2, 'Internal')])
sendtouser = forms.CharField(max_length=30, required=False)
sendtogroup = forms.CharField(max_length=30, required=False)
class Meta:
model = Rules
fields = ['name', 'type', 'enabled', 'rule']
and
class RulesForm(forms.ModelForm):
name = forms.CharField(max_length=30, required=True)
type = forms.CharField(max_length=11, empty_value="UserDefined", required=True
enabled = forms.BooleanField(widget=forms.CheckboxInput)
embedmodel.sendto = forms.ChoiceField(widget=forms.Select, choices=[(1, 'External'), (2, 'Internal')])
embedmodel.sendtouser = forms.CharField(max_length=30, required=False)
embedmodel.sendtogroup = forms.CharField(max_length=30, required=False)
class Meta:
model = Rules
fields = ['name', 'type', 'enabled', 'rule']

I was able to solve this by following https://medium.com/#SiddyZen/create-embedded-models-using-django-admin-3ecc38a00879 (in Section with heading The ‘embedded model’)Thanks to the author SiddyZen :). Did the below change in models.py
from django import forms
class embedmodel(models.Model):
sendto = models.CharField(max_length=10)
sendtouser = models.CharField(max_length=15)
sendtogroup = models.CharField(max_length=15)
class embedmodelForm(forms.ModelForm):
sendto = forms.ChoiceField(widget=forms.Select, choices=[(1, 'External'), (2, 'Internal')])
sendtouser = forms.CharField(max_length=15, required=False)
sendtogroup = forms.CharField(max_length=15, required=False)
class Meta:
model = embedmodel
fields = ['sendto', 'sendtouser', 'sendtogroup']
class parentmodel(models.Model):
name = models.CharField(max_length=30, unique=True, primary_key=True)
type = models.CharField(max_length=11)
enabled = models.BooleanField()
rule = models.EmbeddedModelField(model_container=embedmodel, model_form_class=embedmodelForm)
class Meta:
managed = False
db_table = 'parentmodel'
