python - django-simple-captcha 破坏 Heroku 部署

Question

我正在使用 django-simple-captcha，它在本地运行良好。一旦部署到 Heroku，它所在的页面就会出现 500 错误(我得到的唯一日志输出是 (2017-02-11T13:26:07.367450+00:00 heroku[router]: at=info method=GET path= “/contact/”主机=fathomless-harbor-1234.herokuapp.com request_id=37555c3c-c468-40cb-a142-c7dd04519e2c fwd=“73.163.191.194”dyno=web.1连接=1ms服务=83ms状态=500字节= 386)。

我运行了./manage.py测试验证码并得到了三个失败的测试，所有这些都有类似的错误File“/Users/pmn/.virtualenvs/within/lib/python2.7/site-packages/django/template/loader.py”，第 43 行，在 get_template 中
引发 TemplateDoesNotExist(template_name, chain=chain)
TemplateDoesNotExist:captcha_test/image.html

我使用的是 django 1.9.6 和 django-simple-captcha 0.5.3

表单.py

from django import forms
from django.template.loader import get_template
from django.core.mail import EmailMultiAlternatives

from captcha.fields import CaptchaField


class ContactForm(forms.Form):

    contact_name = forms.CharField()
    contact_email = forms.EmailField()
    contact_phone = forms.CharField()
    content = forms.CharField(widget=forms.Textarea)
    cc_me = forms.BooleanField(required=False, initial=False)
    captcha = CaptchaField(required=True)

    def send_email(self):
        contact_name = self.data["contact_name"]
        contact_phone = self.data["contact_phone"]
        contact_email = self.data["contact_email"]
        content = self.data["content"]

        template = get_template("contact.txt")

        context = {
            "contact_name": contact_name,
            "contact_phone": contact_phone,
            "contact_email": contact_email,
            "content": content,
        }

        content = template.render(context)
        subject, from_email, to = "Inquiry", contact_email, "jason@email.com"
        cc_address = contact_email if "cc_me" in self.data else None
        email = EmailMultiAlternatives(
            subject,
            content,
            from_email,
            ["jason@email.com"],
            cc=[cc_address],
            headers={"Reply-To": contact_email}
        )
        email.send()

    def __init__(self, *args, **kwargs):
        super(ContactForm, self).__init__(*args, **kwargs)
        for field in self.fields:
            self.fields[field].widget.attrs['class'] = 'form-control'

(请注意，如果我注释掉两个验证码行，页面将在部署时加载)

问题是数据库迁移尚未在 Heroku 上运行。 heroku run python manage.py makemigrations 和 heroku run python manage.py migrate 修复了它。
