Cannot find plant assets from crop plan API

Development

Hello,

I am experimenting on crop plans and hoping to programmatically create/add/edit crop plans through an API. Here is the screenshot of the crop plan I manually created from UI.

I can get the plan information by /api/plan/crop endpoint. However, when I requested details on a specific plan by api/plan/crop/{plan_uuid}, I could not see information about plant assets. The return from API is below

I was expecting there would be plant assets in the relationship. I am not sure if I missed something. Does anyone have any suggestions?

Hi @tbureete - welcome to the forum! :smiley:

Great question. The crop plan models things a bit differently than a “default” plan entity. Instead of referencing plant assets via the assets relationship directly on the plan entity, it uses an “in between” entity type called a plan_record which references both the plan and the plant to connect them together. So the plan doesn’t contain any references itself.

The benefit of doing this is we can add additional metadata to the plan_record entity. That’s where we store seeding_date, transplant_days, and maturity_days, 'harvest_days` for each plant asset relationship.

In the case of crop plans, the plan_record entity bundle (aka sub-type) is crop_planting (in the same way other entity types work: crop_planting is to plan_record as crop is to plan or plant is to asset).

You should be able to get a list of all the plan_record entities associated with a plan using the following API endpoint, using the plan UUID:

api/plan_record/crop_planting?filter[plan.id]=bd67af73-ea62-46ec-b23c-a6dbc765a94b

or using the integer ID of the plan:

/api/plan_record/crop_planting?filter[plan.drupal_internal__id]=1

Hope that helps!

Worth noting: we will probably remove the asset and log relationships from crop plans in the future. Those get added to all plan types by default, but can be disabled on a per-plan-type basis. Since they are not being used for crop plans, they should be disabled IMO, but that was missed during development (the module is still in alpha, after all). :slight_smile:

Also notes: @ktohalloran discovered a possible bug with POSTing new plan_record entities, so that may not be working currently. See this issue:

If you can test to confirm that, I can help put together a fix ASAP.
