“/参数 1 处的类型错误必须是 str，而不是 PosixPath"；在 Django 电子商务网站中 [英] "TypeError at / argument 1 must be str, not PosixPath" in django ecommerce website

问题描述

我正在使用 Django 和 Vue.Js 构建电子商务网站.我在 localhost 中托管网站时没有问题.但是当我在 Heroku 上部署我的网站时，出现一个错误，显示TypeError at/argument 1 must be str, not PosixPath".主要是jinja模板的错误.

代码:

{% for category in menu_categories %}.. 声明 ..{% 结束为 %}

解决方案

遇到了同样的问题，试过了，成功了:

STATIC_ROOT=BASE_DIR.as_posix()+静态"

相同的

MEDIA_ROOT=BASE_DIR.as_posix()+媒体"

还必须使用相同的解决方法:

DATABASES = {'defalut':{....'NAME': BASE_DIR.as_posix() +'db.sqlite3',}}

I was building an eCommerce website using Django and Vue.Js. There was no issue while I was hosting the website in localhost. But when I deployed my website on Heroku an error is showing up "TypeError at / argument 1 must be str, not PosixPath". Mainly an error in the jinja template.

{% for category in menu_categories %}

解决方案

Had the same issue, tried this and it worked:

STATIC_ROOT=BASE_DIR.as_posix()+ "static"

the same for

MEDIA_ROOT=BASE_DIR.as_posix()+ "media"

also had to use the same workaround to:

DATABASES = {'defalut':{
....
'NAME': BASE_DIR.as_posix() +'db.sqlite3',
}
}
