如何捕获评论的作者，然后在工具提示中显示？ [英] How to capture a comment's author then display in tooltip?

问题描述

我有一个表单附加到可以提交简短评论的个人资料。我想捕获作者的名字，所以当鼠标悬停在注释的正文上时，我可以在工具提示中显示它。

在我的创建方法在控制器我有：

  def create 
 @comment = Comment.new（params [ ：comment]）
 @ comment.save！ 
 redirect_to profile_path（@ comment.profile）
 end 
  

  t.timestamps 
 t.integer：profile_id 
 t.string：author_id 
 t .string：body 
  

个人资料模式：

  belongs_to：user 
 accepts_nested_attributes_for：user 
 has_many：comments 
  

b $ b

评论模型：

  belongs_to：profile 
  

ProfilesController：

  def show 
 @user = User.find（params [：id]）
 @profile = user.profile 
 @superlative = @ profile.superlatives.new 
 end 
  

而我的形式：

 <％= form_for @comment do | f | ％> 
<％= f.hidden_​​field：profile_id，：value => @ profile.id％> 
<％= f.hidden_​​field：author_id，：value => ＃{current_user.profile.first_name}＃{current_user.profile.last_name}％> 
<％= f.text_field：body％> 
<％= f.submit'添加新的'％> 
<％end％> 
  

我想链接：author_id到current_user.profile.id并使用该关联显示： first_name和：last_name，它们是配置文件的属性。或者有更简单，更好的方法吗？

更新：我得到它显示的名称，虽然我还是好奇，如果有一个更好方法。

解决方案

您的解决方案看起来不错，但我会存储 User （> ： $ b

在 app / models / comment.rb ：

  class Comment< ActiveRecord :: Base 
 
 belongs_to：profile 
 belongs_to：author，：class_name => User，：foreign_key => author_id
 
 ...其余代码... 
 
 end 
  

然后将您的迁移更改为：

  t.integer：author_id 
  

和您的控制器方法：

  def create 
 @comment = Comment.new（params [：comment] .merge（：author_id => current_user.id））
 @ comment.save！ 
 redirect_to profile_path（@ comment.profile）
 end 
  

我使用 title 属性创建一个工具提示，但随意使用任何你喜欢的方法）：

 < div class =commenttitle =<％= @ comment.author.profile.first_name％><％= @ comment.author.profile.last_name％> > 
<％= @ comment.body％> 
< / div> 
  




I have a form attached to profiles where short comments can be submitted. I want to capture the author's name though so I can display it in a tooltip when hovering over the comment's body.

In my create method in the controller I have:

def create
  @comment = Comment.new(params[:comment])
  @comment.save!
  redirect_to profile_path(@comment.profile)
end

Inside my migration:

t.timestamps
t.integer :profile_id
t.string :author_id
t.string :body

Profile model:

belongs_to :user
accepts_nested_attributes_for :user
has_many :comments

Comment model:

belongs_to :profile

ProfilesController:

def show
  @user = User.find(params[:id])
  @profile = user.profile
  @superlative = @profile.superlatives.new
end

And my form:

<%= form_for @comment do |f| %>
  <%= f.hidden_field :profile_id, :value => @profile.id %>
  <%= f.hidden_field :author_id, :value => "#{current_user.profile.first_name} #{current_user.profile.last_name}" %>
  <%= f.text_field :body %>
  <%= f.submit 'Add new' %>
<% end %>

I was thinking of linking the :author_id to current_user.profile.id and using that association to display :first_name and :last_name which are attributes of the profile. Or is there a simpler, better way?

UPDATE: I got it to display the name though I'm still curious if there's a better way.

解决方案

Your solution looks fine, but I'd store the User (or whatever class current_user returns) instead of the Profile:

In app/models/comment.rb:

class Comment < ActiveRecord::Base

  belongs_to :profile
  belongs_to :author, :class_name => "User", :foreign_key => "author_id"

  ... rest of the code ...

end

You then change your migration to:

t.integer :author_id

and your controller method to:

def create
  @comment = Comment.new(params[:comment].merge(:author_id => current_user.id))
  @comment.save!
  redirect_to profile_path(@comment.profile)
end

In your view (I used the title attribute do create a tooltip, but feel free to use whatever method you like):

<div class="comment" title="<%= @comment.author.profile.first_name %> <%= @comment.author.profile.last_name %>">
  <%= @comment.body %>
</div>
