ruby on rails - "Destroy" controller action appears to be looping through more than once -

i have model "comment", belongs_to model "user", in turn has_many comments. on 'users/edit' page, have link destroy comments:

users/edit.html.erb

<% @user.comments.each |comment| %>   <%= link_to "destroy", destroy_comment_path(comment.id) %> <% end %> 

comments_controller

def destroy   @comment = comment.find(params[:id])   @user = @comment.user   @comment.destroy   redirect_to edit_user_path(@user) end 

but i'm getting bizarre error. action appears looping through more once. i'm getting error message:

activerecord::recordnotfound in commentscontroller couldn't find comment id=[id of comment] 

with line being highlighted:

@comment = comment.find(params[:id]) 

the comment exists before call method, , no longer exists after call it. if remove line @comment.destroy action runs expected, , comment isn't destroyed. action must looping through again, after line. can't imagine why doing that. see might going wrong? don't have other actions called "destroy".
