Ruby on rails: I need to render a View with data from two unrelated Models -


i trying create student view student details. in same view, need add collection_select populated values model hobbies (which separated, unrelated model)

now question how access hobbies model in student/id/new view?

can use fields_for this. if yes, how?

all models , controller instance variables accessible in views. do:

# in view <%= f.collection_select :hobbie_ids, hobbie.all, :id, :name, {}, multiple: true %>

or do:

# in controller @hobbies = hobbie.all # in view <%= f.collection_select :hobbie_ids, @hobbies, :id, :name, {}, multiple: true %>

the code above written in assumption have has_and_belongs_to_many :hobbies relationship.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
