ruby-on-rails – 从高级搜索表单保存搜索选项

用户应该能够填写高级搜索表单的选项,然后单击“保存此搜索”链接,该链接将存储他们的选项.有了这个,每个用户都将拥有自定义的默认搜索选项,因此每次访问时都不需要重新输入详细信息.

我认为这对未来很多人都有帮助.

搜索控制器：

def new
    @search = Search.new
    render layout: 'new_application'
  end

  def create
    @search = Search.new(params[:search])
    if @search.save
        redirect_to @search
    else
      render 'new'
    end
  end

  def show
    @user = current_user
    @search = Search.find(params[:id])
    @users = @search.users
    render 'users/index',layout: 'new_application'    
  end

  def update
    @search = Search.find(params[:id])
    if @search.update_attributes(params[:search])
        redirect_to @search
    else
      render 'new'
    end
  end

  def index
    if location = Location.find_by_zipcode(params[:search])
        latitude  = location.latitude * Math::PI / 180 
        longitude = location.longitude * Math::PI / 180 

        locations = Location.search( 
          :geo   => [latitude,longitude],:with  => {:geodist => 0.0..600_000.0},:order => 'geodist ASC',:per_page => 5_000
        ) 
        @users = User.where(zip_code: locations.map(&:zipcode))


          else
            @users = User.search(params[:search])
        end      
      end

  def min_age
    @min_age = params[:min_age].to_i.years
  end

  def max_age
    @max_age = params[:max_age].to_i.years
  end

  def youngest_age
  @youngest_age = params[:youngest_age].years
  end

  def oldest_age
  @oldest_age = params[:oldest_age].years
   end
end

搜索模型：

def users
    @users ||= find_users
  end

    private

    def find_users
      users = User.order(:id)
      users = users.where(gender: gender) if gender.present?
      users = users.where(zip_code: zip_code) if zip_code.present?
      users = users.where(children: children) if children.present?
      users = users.where(religion: religion) if religion.present?
      users = users.where(ethnicity: ethnicity) if ethnicity.present?

      if min_age.present? && max_age.present?
        min = [ min_age,max_age ].min
        max = [ min_age,max_age ].max
        min_date = Date.today - min.years
        max_date = Date.today - max.years
        users = users.where("birthday BETWEEN ? AND ?",max_date,min_date)
        users
      end
      users
    end
  end

搜索表单：

a.adv_search href="#" 
    = image_tag "adv_link.png"
    span Advanced Search
  = form_for @search do |f|
    .form_container
      .row
