Where should I place the score variable when allocating a score to a Model/Object in Ruby/Ruby on Rails?
Question:
Tag: ruby-on-rails,ruby
I have a model in my Rails app for a SalesOpportunity, and running a SWOT analysis (Strength, Weakness, Opportunity, Threat) to decide how good the SalesOpportunity is. Swots belong_to SalesOpportunities and therefore in the SalesOpportunity Model I have a method called update_swot_score which iterates through the Swot objects and calculates a score based on parameters I'm feeding in. All of this works fine.
What I'm wondering is whether I need to add a field to my SalesOpportunity model (let's call it swot_score for simplicity) and to update the instance variable at the end of the update_swot_score method using @swot_score = "results of my calculation", or whether I can directly access a result of the update_swot_score method (ideally in my view - I'll display different partials depending on the result).
What is the Rails way of doing this? Is there a performance efficiency to be gained by using either method?
Answer:
i will suggest to add in the db as a dedicated column to store score...there are few good reasons as why you should do it:-
- dedicated column to store only
score
- easily maintainable even you decide to add/edit new score type in future
- Can be called/updated/modified anywhere throughout your application
- can use callbacks in future as well(on_create,on_update) as its in a
Model
- Performance wise,its awesome as you can
cache it..can also counter_cache and expire too.
Hope it helps
