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?

Same problem here! Nested field of type partial is not working. Any one there to help please?

I have similar problem, but no solution. may be its not possible

Any of you guys able to get this working? I'm also struggling with this issue and nothing seems to work.

Would be nice if someone can help me out.

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

Same problem, solution please???

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?
