Preloading models in Rails


#1

Hi,

I’m fairly new to rails and I need some advice on best practice. I’m
working on an application that has a calendar section (I know, not
another one of those!) and I was wondering, when is it best to query
your database and when is it best to preload a model. In the calendar
app the user will have a month view of entries and was wondering should
I preload all the entries of the month or should I just query the
database whenever the user wants something. I want to preload but I’m
not sure whether it is worth it considering I’m only envisaging a couple
thousand users.

And one more thing, are preloaded models held in the database or on
file.

Thanks in advance,
Richard
