Hello, I have a model like this:
class Car ActiveRecord::Base
def color(c)
where(color = ?,c)
end
end
Suppose that I want to show the red and blue cars. I could do
something like this:
@cars = Car.color('blue') + Car.color('red')
The problem I'm finding is that now, @cars is an array
Pagination obviously doesn't works on Array, but ActiveRecord::Relation set.
You have to rewrite your color selector using 'standard de facto' approach:
class Car ActiveRecord::Base
scope :colored, lambda { |color| where(:color = color) }
end
Then just call:
Car.colored(%w{red blue}).page
2 matches
