Implement a bracketing suspension setup feature

[joel-thompson]

bracketing is explained here: https://www.youtube.com/watch?v=8PLFfZSkgDs&t=126s

what do I need to model?

main objects

• bike (so you can bracket for multiple bikes) model/name, active shock, active fork, user

• fork (choose fork on bike) model/name, available adjustments, user

• shock (choose active shock) model/name, available adjustments, user

not exactly sure how i want to do the association between bike -> fork/shock. probably will need to maintain history in order to not break things if you replace a part. so I will need to associate through another table, and probably use something like state of the nation to keep track.

tracking active suspension parts (association)

part_assignments

• bike_id
• suspension_part_id
• enabled_at
• removed_at

potential available adjustments

• hsc
• lsc
• hsr
• lsr
• sag (always)
• volume spacers
• PSI
• spring

what does a "bracketing session" look like, and how is it modeled?

may rename this to be more generic. i could see having a single one for just doing hard adjustments.

• has a day/location/track
• has multiple runs, each having the full set of adjustments and notes
• lets you say if you liked a particular change, and suggests the next bracket
• when finishing the session lets you select which parameters need further adjustment or whether you are happy (for now)

Work todo

• [x] model for fork and shock

• [x] model for bike

• [x] association for bike / fork / shock

• [x] rest controllers for fork/shock/bike

• [x] finish and specify requirements/models for bracketing session

• [ ] make UI for creating bikes and suspension parts

• [ ] create suspension settings and bracketing session models
