Nominations allow users to suggest data points for inclusion into LiteFarm's seed 🌱 database. Nominations could be many things including crop varieties, task types, expense types, tool types etc.
These documents will attempt to explain how to use the nominations architecture and provide other relevant information.
Lets go through an example for Crops (our first nomination type to be added).
Crop Nominations - EXAMPLE
Nominations need to go through an evaluation workflow in order to be added to our seed database to be offered as templates for other users.
So in we as administrators go to our database and we add the name of our nomination type (CROP) and the name of the workflow group (CROP_NOMINATION) into the ‘nomination_type’ table along with Base object attributes :
nomination_type
name | workflow_group | …Base object |
|---|---|---|
CROP | CROP_NOMINATION | … |
Now that we have named the workflow group to CROP_NOMINATION we can enumerate the steps in the ‘nomination_workflow’ table under that group.
nomination_workflow
id | name | group | …Base object |
|---|---|---|---|
1 | LF_REVIEW | CROP_NOMINATION | … |
2 | NOMINATED | CROP_NOMINATION | … |
3 | EXPERT_REVIEW | CROP_NOMINATION | … |
4 | REJECTED | CROP_NOMINATION | … |
5 | APPROVED | CROP_NOMINATION | … |
At this point we would like to create our nomination system to create a new nomination object when a user selects
- Nominate this crop for inclusion Litefarm’s catalogue
in the “Add New Crop” flow.
On creation of the new crop a new nomination object will be created in the ‘nomination’ table:
nomination
nomination_id | farm_id | nomination_type | assignee_user_id | …Base object |
|---|---|---|---|---|
1 | MyFarm-xyz-saty | CROP | EXPERT-2345-ty | … |
This will also result in a status update in the ‘nomination_status’ table. With references to the
nomination_status
status_id | nomination_id | workflow_status | notes | …Base object |
|---|---|---|---|---|
1 | 1 | 2 | - | … |
Once created the nomination_id will be returned for insertion into the crop table.
crop
nomination_id | …other Crop table columns |
|---|---|
1 |
Hopefully at some point in the future this will also create a task for the assignee. Which will then push more status updates etc.
task
task_id | assignee | task_type | ..other Task table columns |
|---|---|---|---|
45776 | EXPERT-2345-ty | CROP_NOMINATION_EXPERT_REVIEW |
Things to consider
Do you want to save the nomination object as it is now? Is it immutable?
This functionality is not yet implemented.
