Не удалось найти комментарий с помощью 'id' = 5 [ГДЕ "комментарии". "Post_id" =?]

Question

Я не могу удалить комментарии из поста. Все остальное работает нормально. Я могу создавать комментарии, но каждый раз, когда я удаляю, я получаю сообщение об ошибке -Не могу найти комментарий с 'id' = 5 [WHERE "comments". "Post_id" =?] Мой код выглядит хорошо, насколько я могу судить. Я мог бы помочь, пожалуйста!

    flash[:notice] = "Comment was created!"
    redirect_to post_path(@post)
  end

  def destroy
    @post = Post.find(params[:post_id])
    @comment = @post.comments.find(params[:id])
    @comment.destroy

Answer 1

это ваша проблема

  def destroy
    @post = Post.find(params[:post_id])
    @comment = @post.comments.find(params[:id])
    @comment.destroy

    flash[:notice] = "Comment was deleted!"
    redirect_to post_path

  end

redirect_to post_path => Она будет перенаправлена ​​на @post выше.Вы должны изменить на posts_path.Надеюсь, это поможет.
