我正在使用 Python 和 Angular JS 开发一个 Web 应用程序。我正在为我的 Web 服务器使用 Bottle Python 框架。

我的文件如下:

应用程序.py

import json
import os
from bottle import run, route, template, static_file, request, redirect, get, post
import json
#import MySQLdb

#######################
# Static file servers #
#######################

ROOTPATH = ''

@route('/assets/<filepath:path>')
def serve_static(filepath):
    return static_file(filepath, root='static/')


##############
#  Handlers  #
##############

@route('/')
def root():
    return template('index.html')

def main():
    run(host='0.0.0.0', port=55500, debug=True, reloader=True)

if __name__ == '__main__':
    main()

index.html

<!DOCTYPE html>
<html ng-app="astra">
    <head>
        <title> ASTRA DB </title>
        <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.3.14/angular.min.js"></script>
    </head>
    <body ng-controller="mainCtrl">
            <table>
                <tr>
                    <th> Test Case ID </th>
                    <th> Test Case Description </th>
                    <th> Tester Assigned </th>
                </tr>
                <tr ng-repeat="testCase in testDB">
                    <td>{{ testCase.testCaseID }}</td>
                    <td>{{ testCase.testCaseDesc }}</td>
                    <td>{{ testCase.tester}}
                </tr>
            </table>
    </body>
    <script>
        angular.module('astra', [])
               .controller('mainCtrl', ['$scope', function($scope) {
                $scope.testDB = [
                    {
                        "testCaseID" : 1,
                        "testCaseDesc" : "To create a test case table",
                        "tester" : "Veeresh A"
                    },
                    {
                        "testCaseID" : 2,
                        "testCaseDesc" : "To go to wonder la",
                        "tester" : "Veeresh A"
                    },
                    {
                        "testCaseID" : 3,
                        "testCaseDesc" : "Never take a Meru Cab",
                        "tester" : "Pallavi Bansod"
                    },
                    {
                        "testCaseID" : 4,
                        "testCaseDesc" : "To kill a mocking bird",
                        "tester" : "pallavi bansod"
                    },
                    {
                        "testCaseID" : 5,
                        "testCaseDesc" : "To avoid a farha khan movie",
                        "tester" : "Satyajit Patnaik"
                    },
                    {
                        "testCaseID" : 6,
                        "testCaseDesc" : "To talk to the customer care",
                        "tester" : "Mummana Santhoshi"
                    },{
                        "testCaseID" : 7,
                        "testCaseDesc" : "To be late to wherever you go",
                        "tester" : "Deepa Javoor"
                    }
                ];



               }]);

    </script>
</html>

从命令提示符运行 python app.py 时，服务器启动，但是当我在浏览器上输入“localhost:55500”地址时，它会抛出以下错误。

我收到名称错误异常。有人能帮我解决这个问题吗？

最佳答案

我的问题的答案是:

而不是执行以下操作

@route('/')
def root():
    return template('index.html')

这样做:

@route('/')
def root():
    return static_file('index.html', root="views/")

正如 kedar 所说，bottle 和 Angular 具有相似的模板语法。因此，我需要将 HTML 页面用作静态文件，以便在此处坚持 Angular 模板。

关于javascript - 名称错误 : name "something" is not defined - Web App using Angular JS and Python，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29091312/
