django - FieldFile' 对象没有属性 'rfind'

Question

我对 Django 真的很陌生，所以我仍然习惯了表单。我正在尝试在 Django 中发送一封电子邮件，使用表单中所有清理过的数据，包括上传的文件，但我收到错误“FieldFile' 对象没有属性 'rfind'”。当我尝试将文件附加到电子邮件时。这是否意味着必须首先将文件上传到我的项目中的文件夹中，以便文件路径可以引用？

这是我的表格

class Application(forms.Form):
    first_name = forms.CharField(label="First Name", max_length=50)
    last_name = forms.CharField(label="Last Name", max_length=50)
    email = forms.EmailField(label="Email", max_length=80)
    phone = forms.CharField(label="Phone Number", max_length=30)
    resume = forms.FileField(label="Resume", max_length=1000)
    message = forms.CharField(label="Message", max_length=800, widget=forms.Textarea)

我的看法

if request.method == "POST":
        form = Application(request.POST, request.FILES)
        Post = True

        if form.is_valid():
            cleaned_data = form.cleaned_data
            is_valid = True

            applicant = Applicant()
            applicant.first_name = cleaned_data['first_name']
            applicant.last_name = cleaned_data['last_name']
            applicant.email = cleaned_data['email']
            applicant.phone = cleaned_data['phone']
            applicant.resume = request.FILES['resume']
            applicant.message = cleaned_data['message']
            applicant.job = career.name
            date = datetime.datetime.now()
            applicant.save()

            email_context = {'interested': applicant}

            html_content = render_to_string("email/contact/application-html.html", email_context)

            email = EmailMessage('Some is interested in a demo with Atlas', html_content, settings.DEFAULT_FROM_EMAIL,
                                 ['timbaney1989@gmail.com'])
            email.attach_file(applicant.resume)
            email.send(fail_silently=False)


        else:
            is_valid = False

    else:
        form = Application()
        Post = False
        is_valid = False

Answer 1

attach_file()将路径作为参数，而不是 FieldFile .这应该是:

email.attach_file(applicant.resume.path)
