Django ViewDoesNotExist 时

Question

我有一个运行 Twisted 服务的 django 应用程序，该服务无法解析某些小程序的视图。

当我在 Django 开发服务器上运行应用程序时，它加载正常，但是当我在 Twisted 上运行它时，当我在浏览器中导航到这些小程序时，我收到错误 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

我不知道为什么它不会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程序，有些可以使用，有些则不能。如果需要任何其他信息，请告诉我。

这是我的 views.py 文件： 它调用另一个名为 ai2.py 的文件，然后调用 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())

这是完整的回溯：

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