Question

我有一个Django视图，它返回JSON格式的设置配置文件。当我在浏览器中获取它时它工作正常。但是当我尝试获取与其链接的Backbone Collection时，它返回500并显示以下错误消息：“'list'对象没有属性'find'”。

堆栈跟踪：

/usr/lib/python2.7/ConfigParser.py in _interpolate_some
    _interpvar_re = re.compile(r"%\(([^)]+)\)s")
    def _interpolate_some(self, option, accum, rest, section, map, depth):
        if depth > MAX_INTERPOLATION_DEPTH:
            raise InterpolationDepthError(option, section, rest)
        while rest:
            p = rest.find("%")  <-- where the stacktrace leads to
            if p < 0:
                accum.append(rest)
                return
            if p > 0:
                accum.append(rest[:p])
                rest = rest[p:]

无头配置阅读器：

class SectionlessConfig():
    def __init__(self, fp):
        self.fp = fp
        self.sechead = "[root]\n"

    def readline(self):
        if self.sechead:
            try:
                return self.sechead
            finally:
                self.sechead = None
        else:
            return self.fp.readline()

class Settings():
    configuration_file=settings.SHAKEARRAY_CFG_PATH

    def __init__(self):
        self.parser = ConfigParser.SafeConfigParser()

    def get_all_settings(self):
        self.parser.readfp(SectionlessConfig(open(Settings.configuration_file)))

        return self.parser.items('root')

Django视图代码：

def all_settings(request):
    settings_list = seiscomp_settings.get_all_settings()
    settings_array = []

    for name, value in settings_list:
        settings_obj = {}
        settings_obj['name'] = name
        settings_obj['value'] = value
        settings_array.append(settings_obj)

    return JsonResponse(settings_array, safe=False)

我不确定Backbone代码是否会提供很多帮助，但仍然是这样。

'use strict';

Shakescreen.module('Settings', function(Settings, App, Backbone) {
    Settings.Setting = Backbone.Model.extend({
        urlRoot: 'http://localhost:8000/settings',
        idAttribute: 'name',

        initialize: function() {
            console.log('creating setting object');
        }
    });

    Settings.SettingsCollection = Backbone.Collection.extend({
        url: 'http://localhost:8000/settings',
        model: Settings.Setting,

        initialize: function() {
            console.log('initialize empy settings collection');
        }
    });
});

因此，SettingsCollection上的提取返回500，但通过浏览器的GET工作正常（wget也是如此）。有什么提示吗？

Django视图在浏览器中工作正常，在Backbone获取时返回500
