如何为 tag_cloud 使用多个模型? [英] How to use multiple models for tag_cloud?

问题描述

_tags.html.erb

#Version 1 (Just lists out habits tags)
<% tag_cloud Habit.tag_counts, %w{s m l} do |tag, css_class| %>
  <%= link_to tag.name, tag_path(tag.name), class: css_class %>
<% end %>

#Version 2
<% tag_cloud(@tags, %w(css1 css2 css3 css4)) do |tag, css_class| %>
  <%= link_to tag.name, { :action => :tag, :id => tag.name }, :class => css_class %>
<% end %>

我们如何才能在列出 current_user 的习惯和目标、估值、量化的地方获得它?f.text_field :tag_list 是这四个模型各自的_form，也是数据库中单独的表.

How can we get it where it list's out the current_user's habits AND goals, valuations, quantifieds? f.text_field :tag_list is in the _form of each of these four models, which are also separate tables in the database.

我还向四个模型中的每一个添加了以下代码.以下是它寻找估值的方式:

I also added the below code to each of the four models. Here's is how it looks for valuations:

助手

module ValuationsHelper
  include ActsAsTaggableOn::TagsHelper
end

控制器

class ValuationController < ApplicationController
  def tag_cloud
    @tags = Valuation.tag_counts_on(:tags)
  end
end

以及用户模型

  User.tag_counts_on(:tags)
  acts_as_tagger
  acts_as_taggable

我正在使用 acts-as-taggable-on gem，我从 railscasts.如果您需要任何进一步的代码或解释，请告诉我 =]

I'm using the acts-as-taggable-on gem, which I implemented from railscasts. Please let me know if you need any further code or explanation =]

推荐答案

创建一个名为 Tagalicious 的模型.

Create a model called Tagalicious.

因为你想把它放在侧边栏中，所以把它放在 application_controller 中:

Since you want it in the sidebar put this in the application_controller:

before_action :tag_cloud

def tag_cloud
  @tags = Tagalicious.tag_counts_on(:tags)
end

然后在帮助器中:

module TagaliciousHelper
  include ActsAsTaggableOn::TagsHelper
end

然后在模型中:

class Tagalicious < ActiveRecord::Base
  belongs_to :habit
  belongs_to :goal
  belongs_to :quantified
  belongs_to :valuation
  acts_as_taggable
end

tag_cloud:

<% tag_cloud(@tags, %w(css1 css2 css3 css4)) do |tag, css_class| %>
  <%= link_to tag.name, tag_path(tag), :class => css_class %>
<% end %>

希望能澄清一些事情.我不知道如何在您的各种模型中使这一行 <%= f.text_field :tag_list %> 指向 Tagalicious 模型.

Hopefully that will clarify some things. I can't figure out how to make this line in your various models <%= f.text_field :tag_list %> point to the Tagalicious model.

如果您愿意，我们可以在聊天中讨论这个问题，或者针对该特定问题尝试另一个问题.

This is something we can go over in chat if you want or maybe try another question for that specific problem.
