问题 I have two models, Room and Student . Room has_many Student s. Student belongs_to Room . I got an error Room can't be blank when I try to add Student to Room during creating a new Room. My guess is that, upon submission, child object (student) is saved before parent object (room) is saved. Is there a way to bypass the order without remove the NOT NULL setting on room_id? Or my guess is wrong? Or even worse, I am doing it wrong? # app/models/room.rb class Room < ActiveRecord::Base validates

问题 Hi I am currently using the cocoon gem for my rails app and it seems to be working fine since I was able to add and remove the nested associations in my form. However, when I try to console log the callbacks (e.g. "cocoon:after-insert"), there is no console log fired on the console. What could be the reason for this and how can i capture the callback event in my console? I have the gem remotipart bundled in my app too, if this would offer any clue as to why I have been unable to capture the

问题 I am trying to set up users on an asset, and I am running into the problem of not being sure how to pass my max_users method from asset.rb to my JS code. I am trying to use the max_users method with the Cocoon gem to have the "Add Another" button disappears when it reached the specified max_users allowed for that asset. Hardware will always be set with a max_user of 1, while software will never have a max_user value. Max_users works as it should, as does profile_type. The JS works as it is,

问题 Question: I'm working with cocoon gemfile & following the ERB style of it without haml/slim. I have my github here - The branch I'm working on is "cmodel" - Link. The error is: Unpermitted parameter: ingredient_attributes Really what I don't understand is just about everything about the models. I get pluralization is a thing. I get that strong parameters is a thing. My understanding to implement them is a bit fuzzy. I've found the rails guides & edge rails guides too simple for the expanded
