erb - My search feature isn't showing posts without a tag in rails -

i've implemented search feature in rails project, alongside actsastaggableon gem can tag post model, when use search function doesn't show posts no tags, below code:

search controller

class searchcontroller < applicationcontroller     def search       if params[:q].nil?         @posts = []       else         @posts = post.search params[:q]       end     end end 

post model

class post < activerecord::base     acts_as_taggable      def self.search(search)       joins(:tags)       .where("title :search or content :search or tags.name :search", search: "%#{search}%")     end end 

your code produces query inner join, need left join, query with:

includes(:tags).references(:tags).where( # remaining of query 

or write join statement yourself:

joins("left join tags on tags.id=...") # incomplete
