Django ViewDoesNotExist何时启用

Question

我有一个运行在Twisted服务上的django应用程序，它不能解析一些applet的视图。

当我在Django dev服务器上运行应用程序时，它加载得很好，但当我在Twisted上运行它时，当我在浏览器中导航到这些小程序时，我得到了错误Could not import apps.ai_stats.views. Error was: No module named aidb，唯一的问题是aidb.py文件绝对位于这些小程序目录中。我的结构如下。

apps/
    ai_stats/
        __init__.py
        ai2.py
        aidb.py
        models.py
        urls.py
        views.py
    __init__.py
    manage.py
    settings.py
    urls.py
    views.py

我不明白为什么它不能加载这个特定的模块。我在一个应用程序中有一堆不同的小应用程序，一些与此相关，另一些则不然。如果还需要任何其他信息，请让我知道。

下面是我的views.py文件:它调用另一个名为ai2.py的文件，该文件随后调用aidb.py。

from django.shortcuts import render_to_response
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse

import ai2


def index(request):
    # ai2.refresh_cache()
    return render_to_response('ai_stats/index.html', locals())
    # return HttpResponseRedirect(reverse('apps.ai_stats.views.dashboard', kwargs={'env':ai2.PROD}))


def dashboard(request, env):
    ai2.refresh_cache()
    # env = ai2.PROD
    mf_error, mf_data, _ = ai2.AIStats().data_for_chart('most_failures', env=env)
    mc_error, mc_data, _ = ai2.AIStats().data_for_chart('most_calls', env=env)
    wp_error, wp_data, _ = ai2.AIStats().data_for_chart('worst_performing', env=env)
    error = (mf_error or '') + (mc_error or '') + (wp_error or '')
    cache_timestamp = ai2.data_cache['timestamp']
    return render_to_response('ai_stats/dashboard.html', locals())


def drill(request, env, chart):
    # env = ai2.PROD
    row_limit = int(request.GET.get('limit', 100))
    error, data, _ = ai2.AIStats().data_for_chart(chart, env=env, limit=row_limit)
    cache_timestamp = ai2.data_cache['timestamp']
    return render_to_response('ai_stats/drill_%s.html' % chart, locals())


def dash_data(request, env, chart):
    # env = ai2.PROD
    error, data, chart_type = ai2.AIStats().data_for_chart(chart, env=env, params=request.GET)
    r = render_to_response('ai_stats/%s.xml' % chart, locals())
    if chart_type == ai2.GRAPH_CHART:
        r['Content-Type'] = 'text/xml'
    return r


def pop(request, env, chart):
    pop_template = 'pop_mtd'
    if chart == 'all_mtd':
        pop_template = 'pop_all'
    ops_chart = '%s_ops' % chart
    return render_to_response('ai_stats/' + pop_template + '.html', locals())

我不知道为什么，但一时兴起，我决定将文件重命名为aidb2，并更改导入，它起作用了。我根本无法解释。
