3 months ago To give some further troubleshooting information:
I deleted all the broken allocations from the database:
DELETE FROM allocation_allocation WHERE quantity=1 <- easiest way to clear them all
Then I performed the following steps:
racs = Project.objects.get(title="racs")
active = AllocationStatusChoice.objects.get(name="Active")
Allocation.objects.create(project=racs, status=active)Which returns:
>>> Allocation.objects.create(project=racs, status=active)
Traceback (most recent call last):

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'name'That breaks.
I also receive a "We're having a bit of system trouble at the moment. Please check back soon!" if I try to delete the allocation from the django admin interface.
Looking into the error, it's failing to call the name attribute on the resources contained in the allocation. In this case, there are no resources.
Unfortunately I can't assign resources like so:
>>> Allocation.objects.create(project=racs, status=active, resources=[])

<Allocation: Talapas2 (dmajchrz)>This allocation seems to be working.
This may just be a lack of understanding on how to create django objects with complex relationships. I'd love if the Importing Data documentation could be updated with examples of how to create all those resource types using raw python, like you have listed for the Adding Users to Allocations section.
I'm really looking forward to #316, but in the mean time you gotta do whatcha gotta do 😊 I wish I could help with that request, but I'm booked solid until July.
I've opened a PR that includes a proposed fix to silence the error from this issue. Probably not the best way to go about it, but it should work.
What happened?
I'm working through a sync tool to sync our site data from AD/Slurm into Coldfront in preparation for a cutover in the future.
I've been successful creating users, projects, project users, and resources, but I'm running into an error while creating Allocations that I'm unsure how to work around:
I'm not a big django guy but it looks like it's failing to create it because the
projectmodel usestitlerather thanname?If this isn't a bug, could you please provide some direction on how I can create an Allocation using the coldfront shell?
Thanks!!
