EDIT I re-writed the question including more general aspects.
I'm using StringArrayProperty in neo4django, using use_string = True
so it's saved a single string in Neo4j.
When a new model is created, that field type is a tuple, but I need it as a list.
So this is my approach, when updating the field:
self.mystringarray=list(self.mystringarray)
Now the problem is:
How can one search in fields like that one?
The NodeModelManager.filter doesn't seem to work on such a type.
I found the __member field lookup, which is exactly what I was looking for.
