实施新的搜索视图后出现405错误

标签: django python-3.x heroku django-views heroku-postgres

当前使用Django 2.1,Python 3.6,PostgreSQL 11,并将数据库托管在Heroku上。

我正在创建一个充当GUI数据库条目的Web应用程序。我最近Django Front End Search在这里提供了一些搜索代码。该代码与将服务器托管在我的计算机上的测试应用程序一起使用。当我尝试与Heroku托管数据库通信时,我现在看到405错误。

目前,我的网络应用在捐赠者_list.html上列出了捐赠者。我希望在用户执行查询后,将其查询结果发布在donor_list.html上。

这是错误:

不允许的方法:/ device / donor_list /

如果希望搜索结果显示在同一页面上,则需要将它们放在同一视图中,而不是单独的视图中。

class DonorList(ListView):
    context_object_name = 'donors'
    model=models.Donor

    def post(self, request):
        keywords = request.POST.get("ds", "")
        all_queries = None
        search_fields = ('name','email','donation_house__title')
        for keyword in keywords.split(' '):
            ...

尽管要注意,对于搜索来说,通常使用GET请求而不是POST。
