Admin Tools

Administration utilities for managing a neuprint server. Using these tools requires admin privileges on the neuPrintHttp server.

class neuprint.admin.Transaction(dataset, *, client=None)

For admins only. Used to batch a set of operations into a single database transaction.

This class is implemented as a context manager.

Example

with Transaction('hemibrain') as t:
    t.query("MATCH (n :Neuron {bodyId: 1047426385}) SET m.type=TuBu4)")

Transaction constructor.

Parameters:

• dataset – Name of the dataset to use. Required.

• client – Client object to use.

kill()

Kills (rolls back) transaction.

query(cypher, format='pandas')

Make a custom cypher query within the context of this transaction (allows writes).

If writing JSON to a property, be sure to escape single or double quotes, depending on which quote character you use when expressing the string in Cypher.

Example:

import json
from neuprint.admin import Transaction

myprop = {"foo": "bar"}
myprop = json.dumps(myprop).replace("\", "\\").replace("'", "\'")
q = f'''
    MATCH (m:Meta)
    SET m.myproperty = '{myprop}'
'''
with Transaction('my-dataset', client=c) as t:
    t.query(q)
