jinja2.exceptions.TemplateNotFound错误 [英] jinja2.exceptions.TemplateNotFound error

问题描述

我使用烧瓶，当我调用此URL时出现此错误:/login 这是我的登录方法:

i use flask and i got this error when i call this url: /login Here's my login method:

@app.route('/login')
def login():
    if authenticateForPanel():
        return redirect(url_for("panel"))
    else:
        getParam = request.args.getlist('redirect_uri')
        if getParam:
            ref =getParam[0]
        else:
            ref="/panel"
        return render_template( themesDir + g.blogOptions['active_theme']+'/login.html', blogOptions = g.blogOptions, ref=ref )

和回溯:

    raise TemplateNotFound(template)
TemplateNotFound: static/themes/default/login.html

我绝对确定login.html在哪里(static/themes/default/404.html).为什么会发生这种情况?

I am absolutely sure the login.html is there(static/themes/default/404.html).Why can this occur?

推荐答案

您将模板放在错误的位置.从Flask文档中:

You put your template in the wrong place. From the Flask docs:

Flask将在模板文件夹中查找模板.因此，如果您的应用程序是模块，则此文件夹位于该模块旁边；如果是程序包，则该文件夹实际上位于您的程序包内: 请参阅文档以获取更多信息: http://flask.pocoo.org/docs/quickstart/#rendering-templates

Flask will look for templates in the templates folder. So if your application is a module, this folder is next to that module, if it’s a package it’s actually inside your package: See the docs for more information: http://flask.pocoo.org/docs/quickstart/#rendering-templates
