Hello. I'm developing a simple survey plugin and I'm having a hard time getting nested relations to work in forms.

Models I have:

  • Survey
  • Question
  • QuestionChoice

Relationships I have:

  • One Survey may have many Questions.
  • One Question may have many QuestionChoices.

I have only one controller, which is called Surveys. All these models should be managed from this controller! After creating a Survey and switching to update context user sees a Questions field of type partial, which is rendered via $this->relationRender('questions') and is located in controllers/surveys/_questions.htm. Next user should be able to click "Add Question" button and create a new Question. But Question form has a relation field called choices, which should be rendered via partial too. I created this partial in controller/surveys/_choices.htm. But now I get "Relation config doesn't have definition for 'choices'.". It seems like I have to add choices relation to my relation_config.yaml of Surveys controller, like I did with questions relation. But I didn't find any way to refer a nested relation from relation_config.yaml. I tried to call this relation question[choices] and stuff but it didn't work. How can I define relation of relation in my relation_config.yaml or atleast force Questions "sub form" to use Questions controller instead of Surveys?

Or does it mean I can't use $this->relationRender for any relations that have futher $this->relationRender?

I think you should add choices in questions with backend relation config in questions controller.

So controller/surveys/_choices.htm should put in controller/questions/_choices.htm

It seems that there is only one way. I tried to create formwidget, but it doesn't work yet. https://octobercms.com/support/article/ob-21

The only way to create multilevel relationships in the backend is still that way explained in the tutorial?
