I'm trying to use formset to create connections between my Neo4j nodes.
These models have been constructed using the django-neomodel package. They
aren't related using foreign keys, but since this *isn't* an inline formset
that
shouldn't matter, right?
*models.py*
class Person(DjangoNode):
uid = UniqueIdProperty()
name = StringProperty(max_length=50)
created_at = DateTimeProperty(default=datetime.now)
friends = RelationshipTo('Friend', 'FRIENDED', model=FriendRel)
# DjangoNode class must have a Meta class and documentation specifies
'django_node'
class Meta:
app_label = 'django_node'
class FriendRel(DjangoRel):
created_at = DateTimeProperty(default=datetime.now)
class Meta:
app_label = 'django_rel'
*forms.py*
class PersonForm(forms.ModelForm):
class Meta:
model = Person
# don't need fields for automatically assigned keys like `uid` and
`created_at`
fields = ['name']
class FriendRelForm(forms.ModelForm):
class Meta:
model = FriendRel
exclude = () #"creating ModelForm without either 'fields' || 'exclude'
attribute is prohibited"
FriendRelFormSet = formset_factory(FriendRelForm, extra=1)
*form.html*
<div>
<form action="" method="post">{% csrf_token %}
{{ form.as_p }}
<table class="table">
{{ friends.management_form }}
{% for form in friends.forms %}
{% if forloop.first %}
<thead>
<tr>
{% for field in form.visible_fields %}
<th>{{ field.label|capfirst }}</th>
{% endfor %}
</tr>
</thead>
{% endif %}
<tr class="{% cycle "row1" "row2" %} formset_row">
{% for field in form.visible_fields %}
<td>
<!-- Include the hidden fields in the form -->
{% if forloop.first %}
{% for hidden in form.hidden_fields %}
{{ hidden }}
{% endfor %}
{% endif %}
{{ field.errors.as_ul }}
{{ field }}
</td>
{% endfor %}
</tr>
{% endfor %}
</table>
<input type="submit" value="Save"/>
</form></div>
I'm expecting a "friend" formset to appear in the rendered form, but am not
quite sure how to get it there. If I add the following I get an error:
class FriendRelForm(forms.ModelForm):
class Meta:
model = FriendRel
exclude = ()
fields = ['friends']
****ERROR*** django.core.exceptions.FieldError: Unknown field(s) (friends)
specified for FriendRel*
