datatrails-samples 0.20.0

DataTrails Examples

datatrails-samples

Sample python code that uses the datatrails python SDK to manage particular types of assets such as 'doors', 'cards', 'containers' etc.

Only supplied as examples of python code that accesses the datatrails archivist.

No tests - released 'AS-IS'

Installing the samples code

Python 3.9 and later versions are supported.

Use the standard python pip utility:

python3 -m pip install --user datatrails-samples

and this will create 7 entry points:

  - archivist_samples_document
  - archivist_samples_door_entry
  - archivist_samples_estate_info
  - archivist_samples_signed_records
  - archivist_samples_synsation
  - archivist_samples_software_bill_of_materials
  - archivist_samples_wipp

Pre-requisites

Add a token to the file credentials/.auth_token and set some environment vars to specify the archivist endpoint:

export TEST_ARCHIVIST="https://app.datatrails.ai"
export TEST_AUTHTOKEN_FILENAME=credentials/.auth_token
export TEST_NAMESPACE="unique label"
export TEST_PARTNER_ID="acmecorp"
export TEST_VERBOSE=-v

If TEST_VERBOSE is "-v" debugging output will appear when running the examples. Otherwise leave blank or undefined.

Windows using Powershell - at the command prompt set values for environment variables:

$Env:TEST_ARCHIVIST="https://app.datatrails.ai"
$Env:TEST_AUTHTOKEN_FILENAME = '<path of token location>'
$Env:TEST_NAMESPACE = Get-Date -UFormat %s
$Env:TEST_PARTNER_ID = 'acmecorp'
$Env:TEST_VERBOSE = '-v'

TEST_NAMESPACE is set to the date and time value in Unix format, thus providing a unique id upon execution.

TEST_NAMESPACE

If TEST_NAMESPACE is blank or unspecified, any assets or events will be visible to other users running the same examples on the same URL.

Each example creates assets,events that are not visible to other examples. For example the door_entry assets,events etc are not visible to the synsation example.

Note: Assets are only created if they do not already exist according to namespace. If one wants to execute a sample multiple times, feel free to set TEST_NAMESPACE to a different unique id.

Due to restrictions attachments are always uploaded during every example execution.

Events are created every execution of an example - currently no check is done if the event already exists.

EXAMPLES

All examples use a common set of arguments:

export AUTH="-u $TEST_ARCHIVIST -t $TEST_AUTHTOKEN_FILENAME $TEST_VERBOSE"
export ARGS="$AUTH --namespace $TEST_NAMESPACE --partner_id=$TEST_PARTNER_ID"
