Add ability to restrict children. #24
Conversation
Expanding on the already present can_have_children so that it can also be a list in addition to booleans. (Empty list == False, Non-empty == True) The list is list of values similar to those values accepted in a model ForeignKey. If it is a list it is changed into a list of the content type ids of the listed models. i.e. ["self", "app.Model", "Model", Model] With "self" referring to the model on which can_have_children is defined. "app.Model" is an app_label-model dot string. "Model" is a model in the current app. And the last is a Model class or Model instance.
Based on django-polymorphic/django-polymorphic-tree#24 Probably needs django-polymorphic >= 0.6 due to it's use of get_child_type_choices(self, request, action). Fixes django-fluent#31

| Rather than check a list, would it be possible to use a method to check this instead of it having to be a list of classes? I have a case on the roadmap for my personal project that requires me to limit the children by a property of my polymorphic type, and a method would be more generic. |

| You can have a boolean or a list it works either way. |
Ok, great. Sorry for butting in! Thank you for considering my use-case in bd1758b |

The list is list of values similar to those values accepted in a model
ForeignKey. If it is a list it is changed into a list of the content
type ids of the listed models.
i.e. ["self", "app.Model", "Model", Model]
With "self" referring to the model on which can_have_children is defined.
"app.Model" is an app_label-model dot string.
"Model" is a model in the current app.
And the last is a Model class or Model instance.
