Question

我有以下 CreateView

class CreateEmailTemplateView(CreateView):

   template_name = 'frontend/emailtemplates/create.html'
   model = Templates
   fields = '__all__'

   def form_valid(self, form):
      form.instance.user = self.request.user
      return super(CreateEmailTemplateView, self).form_valid(form)

模板模型如下

class Templates(models.Model):
    name = models.CharField(max_length=128)
    template = models.TextField()
    user = models.ForeignKey(User, on_delete=models.CASCADE)

但是当我提交表单时，它并没有保存在数据库中，也没有看到任何错误消息，它只是重定向到同一页面，表单方法是POST < / p>

我想念什么？提交表单后如何显示一些错误/成功消息？

form_valid在发布有效表单数据后被调用。您能否检查您的数据是否有效？您还可以将日志记录添加到form_valid方法中，以确保达到该目的：

import logging


logger = logging.getLogger(__name__)


class CreateEmailTemplateView(CreateView):

    template_name = 'frontend/emailtemplates/create.html'
    model = Templates
    fields = '__all__'

    def form_valid(self, form):
        logger.info('form_valid called')
        form.instance.user = self.request.user
        return super(CreateEmailTemplateView, self).form_valid(form)

Django CreateView无法正常工作
