在使用 Heroku 进行部署时，我不断收到此错误，并且在通过 Travis 运行构建后尝试将其部署到 Heroku 的几个不同报告中得到了它。

No stash entries found.
API request failed.
Message: Invalid credentials provided.
Reference: 
failed to deploy

我没有得到更多信息。我尝试更新我的 Heroku API 密钥，但这似乎不起作用。我已经使用了该Travis setup Heroku命令并手动创建了构建步骤，但我仍然遇到相同的错误。这是我的 .travis.yml 文件的部署部分的样子

部署：提供者：heroku api_key：安全：g3gj25vI58r48P63E...应用程序：heroku-travis-test-01 on：repo：andrico1234/heroku-travis-test

这是一个常见的问题吗？

编辑：添加 Travis 的安装依赖项堆栈跟踪

FormView如果表单有效，我将重定向到上一页。这工作正常，但我如何告诉用户信息已发布？我希望他在重定向后在模态窗口中看到成功消息。

我已经尝试完成request.session，get_success_url但它不符合我的目标，因为用户可以多次提交表单。那么如何在get_success_urlin 中返回任何带有重定向的消息FormView？

我的 FormView

class CatPhotoUploadFormView(FormView):
    template_name = 'blank.html'
    form_class = CatPhotoForm

    def get_success_url(self):
        self.request.session['success_message'] = 'Everything is fine'
        return reverse('cat:detail_cat', args=(self.kwargs['pk'],))

    def form_valid(self, form):
        cat = Cat.objects.filter(id__exact=self.kwargs['pk'])
        for each in form.cleaned_data['attachments']:
            print('****', each, '****', type(each))
            Photo.objects.create(photo_path=each, photo_author=self.request.user, photo_cat = cat[0])
        return super(CatPhotoUploadFormView, self).form_valid(form)

插入语句如下所示：

INSERT INTO events(ts, domain, url, lat_lon, sha1_hash)
VALUES (STR_TO_DATE(%s, '%Y-%m-%dT%H:%i:%sZ'), %s, %s, %s, sha1(url))

当我尝试使用executemany发送批处理时，出现此错误：

我有一个Django项目,我将用户扩展为使用OneToOneField获取配置文件.我正在使用CBV UpdateView,它允许用户更新他们的个人资料.他们访问的URL是../profile/ user/update.我遇到的问题是,如果用户键入其他用户名,他们可以编辑其他人员个人资料.如何限制UpdateView,以便经过身份验证的用户只能更新其配置文件.我试图做一些事情来确保user.get_username == profile.user但没有运气.

我是Python的新手,我正在尝试创建一个通过PyMySQL将数据保存到数据库的表单,但是我在连接数据库时遇到了问题.我已经按照示例代码(我的版本在下面)并彻底检查了所有语法和语音标记,但仍然收到以下错误.
