在微博中将评论作为'current_user'(设计)发布的问题?

这就是我将Micropost发布为current_userDevise)的方式:

microposts_controller.rb:

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

这是我在微博中发表评论的方式:

comments_controller.rb:

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

现在我想发表评论current_user

为了实现这个目的,有什么建议吗?

微柱/ 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 %>

编辑:

不确定是否需要看到这个,但以下是模型:

comment.rb:

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

  belongs_to :micropost
  belongs_to :user
end

micropost.rb

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

  belongs_to :user
  has_many :comments
end

user.rb

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

答案 0 :(得分:2)

在comments_controller中尝试这个:

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,我认为您的评论没有附加用户..

编辑 - 我更改了:用户为:user_id。更有意义,因为我们还没有评论。
