Adding nodes via tastypie api - lft cannot be null

[Kevin Brolly]

Hi there,

I am trying to add nodes to an mptt tree via my tastypie API.

The nodes are being passed in with an integer id already assigned, but
this seems to be causing the error: IntegrityError: (1048, "Column
'lft' cannot be null")

Does django-mptt not allow nodes to be assigned an id when first
created?

Thanks,
Kevin
