Ruby On rails 过滤器数量最小值和最大值

Question

Hi I need when I type minimum number and the maximum number to show all the cars in between something like this https://www.lpauto.ca/used-cars-vancouver?Makes=Audi

Here is my form

<%= form_for "",url: cars_path, role: "search", method: :get do %>
     <%= text_field_tag :searchp, @search_pricen_term,placeholder: "Min..." %>
     <%= text_field_tag :searchpx, @search_pricex_term,placeholder: "Max..." %> 
<% end %>

In the controller in index

if params[:searchp]
  @search_pricen_term = params[:searchp]
  @cars= @cars.search_by(@search_pricen_term)
end

In the model

def self.search_by(search_pricen_term)
  where("price <= :search_pricen_term OR price >= :search_pricex_term ",
  search_pricen_term: search_pricen_term )
end

Updated the where condition in the model class by using 'scope' which receives both minimum and maximum value and returns all the cars between the given range. Hope this helps.

In the controller, pass both minimum and maximum value to the model.

  if params[:searchp] || params[:searchpx] 
    @search_pricen_term = params[:searchp]
    @search_pricex_term = params[:searchpx] 
    @cars = Car.between_range(@search_pricen_term, @search_pricex_term)
  end

In View,

    <%= form_for "",url: cars_path, role: "search", method: :get do %>
       <%= text_field_tag :searchp, @search_pricen_term,placeholder: "Min..." %>
       <%= text_field_tag :searchpx, @search_pricex_term,placeholder: "Max..." %> 
       <%= submit_tag "Submit" %>
     <% end %>

In the model,

     scope :between_range, -> (min, max) { where("price >= ? OR price <= ?", min, max) }
