Create and Use Sample Templates 🧪

Inventory Beta is available to all existing and new Enterprise customers, and will be available to Community users in the near future. Learn more at the RSpace Inventory Hub.

Introduction

When working with samples, you might add custom fields to a sample to include relevant information about it, and notice that you're regularly duplicating that sample to reuse the same custom fields for new samples. This is where using sample templates comes in handy.

Templates can be created from scratch, or from existing samples. By creating a template and editing it to your liking, you are able to reuse the structure of a specific sample for future samples. This enables you to create samples with a consistent format, as well as ensuring that fields that are required for safety or regulatory purposes are included for each sample of that type.

  3. Your sample will then be updated to the latest template version, following the rules below with any changes to the template reflected in the sample.

Update All Samples to New Template Version

  1. When viewing the template, select Info, then Update Samples in the sidebar that appears.
  2. Click on Update All if you are happy with how updating the template version will affect your samples.
  3. You will get a confirmation that your samples have been updated. You can click on the dropdown arrow in the notification to expand it and obtain direct links to the samples that were updated.
Rules for applying template changes to existing Samples

Here is a set of rules that are applied when updating a Sample (S) to a newer template version (T).

In brief, these attempt to apply changes if they are compatible with existing data and won't delete or remove existing data.

  1. Check difference between T and S properties:
    • If T has new subsample alias, update subsample alias of S
  2. For each S field check difference between S field and connected T field:
    • if the connected T field was deleted:
      • if the S field value is empty, delete the S field
      • if the S field value is not empty, REJECT WHOLE UPDATE ATTEMPT
    • if the connected T field was renamed, rename the S field
    • if the connected T field is radio/choice, and there is new option set:
      • if the S field value is valid with new T option set, update the S field option set
      • if the S field value is not valid with new T option set, REJECT WHOLE UPDATE ATTEMPT
  3. for each T field, if there is no connected S field (i.e. it's a new field added to T):
    • add the field to S, with empty value (even if T field has a default value, it shouldn't be used)
