I have a few questions about how well RoR performs under various 'irregular' circumstances. First, how quickly does rails work when there are potentially lots of embedded ruby expressions (hundreds) per page? Also, how well does ruby do when there are perhaps hundreds of database reads per page?
In the app I am designing, there would be a list of messages (let's say 50 per page in this example, but it might be more.) Each message could have 0 from a group of several 'tags' applied (funny, serious, sad, happy, etc...) and I want to to show these tag counts next to the subject line of the message (only if they are > 0.) This means one of two things has to happen: I either have to add an integer column to the messages table for every one of the tag categories (the number of categories is likely to grow up to 30+.) Or I have to add a table for these count numbers and do a separate activerecord lookup for each one of the categories for each of the messages on the page (which really adds up!) To give you an example, here's how one message might look: * Hey Guys, I'm trying Ruby on Rails (Happy x3) (Funny x5) (Geeky x10) What is the best way to model this for the best performance? Remember that there could be dozens of other tags that are not displayed (because they are 0, or for other reasons.) Is there any way to store a hash (or, if no other way an array of key value pairs) in an active record class? Many thanks for any advice you can give. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
