Working with Files¶

To demonstrate working with files, we notice that DataSheet is an extension of CogniteFile in the WindTurbine model

In [2]:

from wind_turbine import WindTurbineClient

from wind_turbine import WindTurbineClient

In [3]:

pygen = WindTurbineClient.from_toml("config.toml")

pygen = WindTurbineClient.from_toml("config.toml")

Listing file metadata¶

We can list the filemetadata directly with the data_sheet attribute

In [5]:

files = pygen.data_sheet.list(limit=5)
files

files = pygen.data_sheet.list(limit=5) files

Out[5]:

Retriving File Content¶

To retrieve data points we use the .select() method in the same way as when we do regular queries.

For example, if we want to view the data_sheet for the hornsea_1_mill_1 turbine:

In [6]:

from pathlib import Path

from pathlib import Path

In [9]:

my_dir = Path("my_dir")
my_dir.mkdir()

my_dir = Path("my_dir") my_dir.mkdir()

In [10]:

(pygen.wind_turbine.select().name.equals("hornsea_1_mill_1").datasheets.content.download(my_dir))

(pygen.wind_turbine.select().name.equals("hornsea_1_mill_1").datasheets.content.download(my_dir))

In [11]:

list(my_dir.iterdir())

list(my_dir.iterdir())

Out[11]:

[WindowsPath('my_dir/windmill_schematics.pdf')]

In [13]:

# cleanup
import shutil

shutil.rmtree(my_dir)

# cleanup import shutil shutil.rmtree(my_dir)
