Could anyone tell me good options for generating search conditions.  
Specifically I have parameters based on time (today, yesterday, etc)  
and I want a private method in a model to generate a conditions  
statement.  
The only way I can think to do it is something like :

(pseudocode)  
def gen\_conditions(part)  
if part == “today”  
return “submitted at \< date”  
else if part ==“yesterday”  
return “submitted at \< date”  
end  
end

This would probably work, but I’m thinking there might be a better  
way. Thanks for any advice.

JB
