不区分大小写和包含ActiveRecord的查询？

Question

I have views that print out a table of guides that have the word 'farming' in their titles.

  def farming
   t = Guide.arel_table
    @guides = Guide.where(t[:title].matches('%farming'))
  end

The problem is I want to show all guides that have at least any kind of spelling of the word 'farming' in it. So "Farming for Dummies" should show up in the search, too.

How do I do this?

Answer 1

In order to match Farming for Dummies you need to use farming% , ie % should be after the word farming .

Try the following to return all records with title including the word farming anywhere in title :

def farming
  t = Guide.arel_table
  @guides = Guide.where(t[:title].matches('%farming%'))
end
