如何根据标签调用text_field?

我不知道这是否可行,但如果用户在评估表单中创建了一个名为mission-statement的标记:

<%= f.text_field :name %>
<%= f.text_field :tag_list, valuation: @valuation.tag_list.to_s.titleize %>

我们如何才能在主页:name中显示该估值的:jumbotron

<% content_for :jumbotron do %>
      <h1>Mission</h1>
      <p>
        # Mission Statement Goes Here
        <% @valuation_mission.each do |valuation_mission| %>
          <%= valuation_mission.name %>
        <% end %>
      </p>
<% end %>

我认为我们必须在pages_controller中编写一个方法,就像我尝试的那样:

class PagesController < ApplicationController
  def home
      @user = current_user
    if logged_in?
      @habits = current_user.habits
      @valuations = current_user.valuations
      @accomplished_goals = current_user.goals.accomplished
      @unaccomplished_goals = current_user.goals.unaccomplished
      @averaged_quantifieds = current_user.quantifieds.averaged
      @instance_quantifieds = current_user.quantifieds.instance
      @valuation_mission = current_user.valuations #We'd need to add .something to make this work?
      @feed_items = current_user.feed.paginate(page: params[:page])
    end
   end
end

我正在使用act-as-taggable-on gem,我从这里学会了如何实现:http://railscasts.com/episodes/382-tagging

感谢您的时间!

您可以使用:

current_user.valuations.tagged_with('mission-statement')
