Ruby on rails 将评论发布为'；当前用户'；（设计）在一个微观世界？

这就是我将Micropost发布为当前用户的方式：

microposts\u controller.rb:

 def create
    @user = current_user
    @micropost = @user.microposts.new(params[:micropost])
    @micropost.save
    redirect_to @micropost
  end

  def create
    @micropost = Micropost.find(params[:micropost_id])
    @comment = @micropost.comments.create(params[:comment])
    redirect_to micropost_path(@micropost)
  end

class Comment < ActiveRecord::Base
  attr_accessible :content, :user_id

  belongs_to :micropost
  belongs_to :user
end

以下是我在micropost中发表评论的方式：

评论\u controller.rb:

 def create
    @user = current_user
    @micropost = @user.microposts.new(params[:micropost])
    @micropost.save
    redirect_to @micropost
  end

  def create
    @micropost = Micropost.find(params[:micropost_id])
    @comment = @micropost.comments.create(params[:comment])
    redirect_to micropost_path(@micropost)
  end

class Comment < ActiveRecord::Base
  attr_accessible :content, :user_id

  belongs_to :micropost
  belongs_to :user
end

现在我想以

current\u用户的身份发表评论

为了实现这一点，有什么建议吗

microspost/show.html.erb

<h2>Add a comment:</h2>
<%= form_for([@micropost, @micropost.comments.build]) do |f| %>
  <div class="field">
    <%= f.label :content %><br />
    <%= f.text_area :content %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

class Micropost < ActiveRecord::Base
  attr_accessible :title, :content

  belongs_to :user
  has_many :comments
end

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me

  has_many :microposts
  has_many :comments
end

添加注释：



编辑：

不确定您是否需要查看此信息，但以下是模型：

comment.rb:

 def create
    @user = current_user
    @micropost = @user.microposts.new(params[:micropost])
    @micropost.save
    redirect_to @micropost
  end

  def create
    @micropost = Micropost.find(params[:micropost_id])
    @comment = @micropost.comments.create(params[:comment])
    redirect_to micropost_path(@micropost)
  end

class Comment < ActiveRecord::Base
  attr_accessible :content, :user_id

  belongs_to :micropost
  belongs_to :user
end

class注释

microspost.rb

<h2>Add a comment:</h2>
<%= form_for([@micropost, @micropost.comments.build]) do |f| %>
  <div class="field">
    <%= f.label :content %><br />
    <%= f.text_area :content %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

class Micropost < ActiveRecord::Base
  attr_accessible :title, :content

  belongs_to :user
  has_many :comments
end

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me

  has_many :microposts
  has_many :comments
end

class Micropost

user.rb

<h2>Add a comment:</h2>
<%= form_for([@micropost, @micropost.comments.build]) do |f| %>
  <div class="field">
    <%= f.label :content %><br />
    <%= f.text_area :content %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

class Micropost < ActiveRecord::Base
  attr_accessible :title, :content

  belongs_to :user
  has_many :comments
end

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me

  has_many :microposts
  has_many :comments
end

class用户
在您的评论中尝试以下内容：

def create
  @micropost = Micropost.find(params[:micropost_id])
  comment_attr = params[:comment].merge :user_id => current_user.id
  @comment = @micropost.comments.create(comment_attr)
  redirect_to micropost_path(@micropost)
end

到目前为止，我认为你的评论没有附加用户

编辑-我更改了：user to be:user_id。这更有意义，因为我们还没有评论。
如何在新评论中设置
user
属性？它不是attr_accessiable@yoavmatchulsky对不起，我改了。注释具有
user\u id
属性。感谢您的帮助，但我得到以下信息：
