tablecrow 1.0.2

abstract interface with remote database table

TableCrow

tablecrow is an abstraction library over a generalized database table. Currently, tablecrow offers an abstraction for PostGreSQL tables with simple PostGIS operations.

pip install tablecrow

Python API:

from datetime import datetime

from tablecrow import PostGresTable


hostname = 'localhost:5432'
database = 'postgres'
table = 'test'

username = 'postgres'
password = '<password>'

# parameters for an SSH tunnel
ssh_hostname = None
ssh_username = None
ssh_password = None

fields = {
    'id'    : int,
    'time'  : datetime,
    'length': float,
    'name'  : str
}

table = PostGresTable(hostname, database, table, fields, username=username, password=password,
        ssh_hostname=ssh_hostname, ssh_username=ssh_username, ssh_password=ssh_password)

table.insert([
    {'id': 1, 'time': datetime(2020, 1, 1), 'length': 4.4, 'name': 'long boi'},
    {'id': 3, 'time': datetime(2020, 1, 3), 'length': 2, 'name': 'short boi'},
    {'id': 2, 'time': datetime(2020, 1, 2)}
])

table[4] = {'time': datetime(2020, 1, 4), 'length': 5, 'name': 'long'}

record_with_id_3 = table[3]
short_records = table.records_where({'name': 'short boi'})
long_records = table.records_where({'name': '%long%'})
early_records = table.records_where("time <= '20200102'::date")
