acts_as_votable大拇指向上/向下按钮(acts_as_votable thumbs u

我安装了acts_as_votable宝石，它工作在控制台像它应该（像它在文档中说的）。 所以我的问题是如何建立一个形式给予好评和downvote按钮？ 或者他们仅仅是链接？

这里是文档：github.com/ryanto/acts_as_votable/blob/master/README.markdown

我有一个用户的图像模型; 用户应该能够像图片。 从图片视图，其中该按钮应该是代码：

<% for picture in @pictures %> 
<p> 
<%= image_tag picture.image_url(:thumb).to_s %> 
</p> 
<%= picture.created_at.strftime("%a, %d %b. %Y") %>, by 
<%= link_to picture.user.name, picture.user %> 
<h2> <%= link_to picture.name, picture %></h2> 

[buttons here] 

<%= picture.votes.size %> <% end %>

Answer 1:

这样做的一个办法是增加你自己的控制器动作上调和downvotes。 我假设你有一个current_user在控制器可用的方法。

# pictures_controller.rb
def upvote
  @picture = Picture.find(params[:id])
  @picture.liked_by current_user
  redirect_to @picture
end

def downvote
  @picture = Picture.find(params[:id])
  @picture.downvote_from current_user
  redirect_to @picture
end

# config/routes.rb

resources :pictures do
  member do
    put "like", to: "pictures#upvote"
    put "dislike", to: "pictures#downvote"
  end
end

# some view

<%= link_to "Upvote", like_picture_path(@picture), method: :put %>
<%= link_to "Downvote", dislike_picture_path(@picture), method: :put %>

Answer 2:

以下是我结束了与acts_as_commentable宝石做了。 因此，我认为这应该与你有任何意见的对象工作。

在我_comment.html.erb视图

<%= link_to "Upvote", {:controller =>"comments", :action => "upvote", :id => comment.id}, :class => 'btn', method: :put %>
<%= link_to "Downvote", {:controller =>"comments", :action => "downvote", :id => comment.id}, :class => 'btn', method: :put %>

在我的routes.rb文件

put '/comments/:id/:action' => 'comments#upvote'
put '/comments/:id/:action' => 'comments#downvote'

然后，在我的意见控制器

class CommentsController < ApplicationController
  before_filter :load_commentable
  before_filter :find_comment, :only => [:upvote, :downvote]



  def upvote
    current_user.upvotes @comment
    redirect_to(@comment.commentable)
  end

  def downvote
    @comment.downvote_from current_user
    redirect_to(@comment.commentable)
  end




private

  def load_commentable
    resource, id = request.path.split('/')[1, 2]
    @commentable = resource.singularize.classify.constantize.find(id)
  end

  def find_comment
    @comment = Comment.find(@commentable.id)
  end


end

该过滤器之前允许更多的灵活性，所以我可以将它添加到任何commentable对象。 矿正好是节日，但你可以做的图片或任何东西真的。 退房acts_as_commentable文档，并在该信息的多态性railscast。 这是我的第一篇文章，所以如果这是很可怕的代码，请告诉我。
