Python ValueError:以10为基数的int（）的文本无效：'；slug-1-2'；

ValueError:基数为10的int（）的文本无效：“slug-1-2” 第二次我再次面临这个错误。我试图允许用户在任何博客文章中编辑他们的评论，但这一行似乎有问题：

comment=get\u object\u或\u 404（comment，id=post\u id）

这对其他函数（例如，当我创建一个可以删除注释的函数时）有效，但对这个函数无效。你知道我该怎么解决这个问题吗？当我在我使用slug的url中添加评论和编辑评论url时，我有一种感觉。但它对我的delete函数有效，我确实使用了post_id来实现该函数。谢谢

        if comment.name == request.user and form.is_valid():
            obj = form.save(commit=False)
            #this prints a success message after it is safe

    form = UpdateCommentForm(
            initial = {
                    "body": comment.body,
            }
        )

    context['form'] = form
    return render(request, 'HomeFeed/edit_comment.html', context)

看起来这里的问题在于您的url，如下所示：

path('edit-own-comments/<int:post_id>', edit_own_comment, name="edit_own_comment"),

在您获得评论的视图中：

{% if comment.name == request.user %}
    <a class="btn btn-sm btn-warning col-lg-4" href="{% url 'HomeFeed:edit_own_comment' comment.id %}">Edit comment</a> <!-- here change comment_id to comment.id to pass the correct value to the url -->
{% endif %}

comment = get_object_or_404(Comment, id=post_id) # also rename post_id to something like comment_id here and in the url to make it more readable

它应该能工作。

错误到底是什么时候发生的？哈哈，我的救世主，它发生在这行代码中

comment=get\u object\u或\u 404（comment，id=post\u id）

在编辑\u own\u comment视图下其他代码都能工作，只有这行代码不工作。你需要追踪吗？那会很有帮助的yes@SLDem添加兄弟，不知道为什么slug会显示，即使我使用了post_id。我感觉这与我在url中添加评论和编辑评论时使用slug有关。但我不太确定如何将其重新命名。我也在delete comment视图中使用了post_id，它很有效。Hi bro正在添加int，因为我不必为其他URL添加int@SLDem，还有，您介意演示如何使用注释实例id的值吗？你的意思是post\u id=post\u id吗？你使用的url是

/HomeFeed/editowncomments/slug

，而不是传递

id

（它是一个int）你传递了str类型的'slug'，因此出现了错误，你用

id='slug'

：）来查询你的评论，所以我所要做的就是更改url？然后在我的模板上，它将是

是的，但是

post\u id

参数实际上必须类似于

comment\u id

，因为您正在使用ITI bro查询注释，sry ah lemme编辑我的代码，您可以看到我是否理解您的意思
