Best way to display recently changed objects?

Rails
1

I’m trying to create a list of recently changed objects…

but…

@events = Event.find :all, :limit => 2, :order => ‘updated_at desc’
@videos = Video.find :all, :limit => 2, :order => ‘updated_at desc’
@recently = [@events, @videos].sort_by(&:updated_at).reverse

gives a…

undefined method `updated_at’ for #Array:0x24ecf30

Any ideas of best practice for this type of thing?

that’s because the elements of the array you are sorting are the 2
arrays you fetched previously

You want something like

(@events + @videos).sort_by(&:updated_at).reverse

Fred already explained the problem.

Let me add a remark: that code looks like something that belongs to
some controller. If that’s the case, in a controller finds like those
are better encapsulated in the models, using named_scope in recent
Rails, or a regular method in previous ones:

class Event
…
def recent
find :all, :limit => 2, :order => ‘updated_at desc’
end
end

so that the controller just says:

@recently = (Event.recent +
Videos.recent).sort_by(&:updated_at).reverse

Thanks, yes, you are right.
