按照 ruby-china 的 commetscell 写，但是运行时出现了这个错误 uninitialized constant CommentsCell::Comment，rails 3.1 and cells 3.8
class CommentsCell < Cell::Rails
def show(opts)
@commentable = opts[:commentable]
@current_user = opts[:current_user]
@comments = Comment.where(:commentable_type => @commentable.class.name, :commentable_id => @commentable.id)
@comment = Comment.new(:commentable_type => @commentable.class.name, :commentable_id => @commentable.id)
render
end
end
目录结构 app/cells/comment_cell.rb app/cells/comments/ app/cells/comments/_comment.html.erb app/cells/comments/show.html.erb
无引用文章
ActionView::Template::Error (uninitialized constant CommentsCell::Comment):
15: </span>
16: </div>
17: <div class="comments_show">
18: <%= render_cell :comments, :show, :commentable => @micropost, :current_user => current_user %>
19: </div>
20: </td>
21: </tr>
app/cells/comments_cell.rb:6:in `show'
@huacnlee 这里
class Comments < ActiveRecord::Base
attr_accessible :comment
belongs_to :user
belongs_to :comentable, :polymorphic => true
index :user_id
index :commentable_type
index :commentable_id
validates_presence_of :comment
end
@huacnlee 又有这个错误了 model 我已经去到个 s····
ActionView::Template::Error (undefined method `index' for #<Class:0x007f980d7d53c8>):
15: </span>
16: </div>
17: <div class="comments_show">
18: <%= render_cell :comments, :show, :commentable => @micropost, :current_user => current_user %>
19: </div>
20: </td>
