Ransack是否有实现令牌搜索的方法

Question

Now I have search_field

= f.search_field :name_cont

I want to create a list of extra words(tokens) that will show a different query.

For example, if I type John it will show all Johns, but if I type [] it will show all users without a name.

One more: @ - will means users with a name.

New implementation also welcome.

In the controller, you can modify the search params according to any logic you like. Eg, assuming your search params are saved in a @search_params (replace with whatever var has your search params, eg params[:q] ):

if @search_params[:name_cont] == "[]"
  @search_params[:name_blank] = true
  @search_params.delete(:name_cont)
end
if @search_params[:name_cont] == "@"
  @search_params[:name_present] = true
  @search_params.delete(:name_cont)
end
