保存高级搜索表单中的搜索选项

我有一个高级搜索表单,我想向用户提供保存选项的选项。我怎么能做到这一点?

用户应该可以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。

我认为这对未来的很多人都有帮助。

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
        .col
          label I am a
          select.large

        .select2
          .col.col2
            label Seeking
            = f.select :gender, %w(Female Male)
        .select1
          .col.col3
            label Ages
            = f.select :min_age, options_for_select((18..50),25), {}, {class: 'small'}

        input.find_btn type="submit" value="Find" /

如果您不想将它们存储在模型中,最好的方法是存储在序列化哈希中。我已经为一个应用程序做了这个,我需要管理员来保存他们的偏好/设置。我尝试了很多宝石,最后我使用了rails-settings

即,在您的用户模型中,您可以执行以下操作:

class User < ActiveRecord::Base
  has_settings do |s|
    s.key :search_options,  :defaults => { :gender => 'male'}
  end
end

然后设置/保存设置,您可以执行以下操作:

user.settings(:search_options).gender = 'female'
user.save!

我喜欢这种方法的原因是它的占地面积很小,如果你开始看到可扩展性问题,那么很容易将其剥离并实现完整的优化模型。

<强>持久性

我个人希望将您的数据保存在另一个关联模型中,如下所示:

#app/models/user.rb
Class User < ActiveRecord::Base
   has_one :search
   delegate :input, :advanced, :options, to: :search, prefix: true
end

#app/models/search.rb
Class Search < ActiveRecord::Base
   #fields id | user_id | input | other | advanced | options | created_at | updated_at
   belongs_to :user
end

这意味着如果您能够通过创建“搜索”选项填充模型,您将能够创建所需的功能

现在,作为一个警告,我不知道你的Search模型现在做了什么 - 但我会详细说明如果 {em>我将如何模型只是出于我自己的想法:

Search

这使您能够使用特定于用户的高级选项填充表单:

#app/controllers/application_controller.rb
Class ApplicationController < ActionController::Base
   before_action :set_search

   private

   def set_search
      @search_option = current_user.search_input if user_signed_in?
   end
end

如果存在用户

,这将设置默认选项

<强>模型

当然,这意味着您必须为您的用户创建另一个模型/数据库条目。但是,这也意味着您可以在不同的调用中保留选项

您对多个“默认”搜索参数的描述是我不完全理解的 - 但包括处理它的模型将使您能够确保数据保持持久

要填充#app/views/shared/_search.html.erb <%= form_tag search_path do |f| %> <%= text_field_tag :search, value: @search_option %> <%= submit_tag "Search" %> <% end %> 模型,您必须在创建新查找时调用/创建关联对象:

Search

我想,在查看您的代码之后,一种更简洁的方式来管理搜索对象使用关联:)
