kandi X-RAY | ancestry Summary

ancestry is a Ruby library typically used in Server, Application Framework, Ruby On Rails applications. ancestry has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Ancestry is a gem that allows the records of a Ruby on Rails ActiveRecord model to be organised as a tree structure (or hierarchy). It employs the materialised path pattern and exposes all the standard tree structure relations (ancestors, parent, root, children, siblings, descendants), allowing all of them to be fetched in a single SQL query. Additional features include STI support, scopes, depth caching, depth constraints, easy migration from older gems, integrity checking, integrity restoration, arrangement of (sub)trees into hashes, and various strategies for dealing with orphaned records.

            How do I relate Ancestry gem data in Administrate gem
            Asked 2020-Sep-08 at 11:02

            I'm using the Administrate gem in my Rails 6 application. I have created a category model and I'm using the ancestry gem to organise the tree structure etc. I'm having trouble trying to integrate the ancestry gem into Administrate. Mainly an issue where the parent_id for ancestry gem is null so and 2. trying to display the child name/relationships in Administrate.

            1. The Administrate gem because of the relationship will not accept a null value when editing the form is "ancestry" is added to the dashboard form in administrate.
            2. Another problem I am trying to overcome is displaying the associated name of a child the id that ancestry uses. So ancestry using a string field which helps locate the parent using the id of the category row. I have no idea how to manipulate the Administrate dashboard/controller to display the field name.

            Any help would be so much appreciated. I've googled this one for a bit and cannot seem to find anything related to the same problem.

            Is it worth using Ancestry and Administrate together? Or should I just create my own category controller and views to allow Admin to modify the category data? I'd prefer to try to keep all admin stuff in Administrate if possible.

            Thanks a mil.
