Is it possible to pass a model name as a variable?

Rails

Hi all,
Is it possible to pass a model name as a variable?
For example in controller there is a method like this,

def list
var = User.find(:all)
end

where in var we heve collected all data from users table. If i edit the
above code like the one below, will it do the same work?

def list(modl)
var = tab.find(:all)
end

def hi
tab = User
list(tab)
end

someone please help.

thanks,
shanmu

Yes it will but you have a bug in your code, it should be:

def list(modl)

Yes it will but you have a bug in your code, it should be:

def list(modl)
var = modl.find(:all) #Must call find on modl, not tab
end

def hi
tab = User
list(tab)
end

Can be simplified as:
def list(modl)
modl.find(:all)
end

def hi
list(User)
end
