ruby on rails - Convert query from SQL to ActiveRecord -


how can same result using activerecord? 

select categories.* categories inner join levels on levels.id = categories.level_id levels.description <= "medium"

it's hard precise without more details, should that:

category.joins(:level).where('levels.description <= "medium"')

i think should trick:

category.joins(:level).where(level.arel_table[:description].lteq('medium'))
