Django：无法导入模块

Question

我正在尝试将views.py中的模块导入为

from django.shortcuts import render

# Create your views here.
from viewcreator import Builder
import json
def index(request):

    a,b=Builder.buildChartJSON()
    print(json.dumps(a))  
    print(json.dumps(b))
    return render(request, 'hdfsStats/hdfscharts.html',
                  {'sourcepoints': a, 'sizepoints': b})

以及我的项目设置如何

为什么我不能在我的视图中导入模块？我不想在models.py中创建这些类。这些类只是为了运行一些计算并返回两个json对象，然后将其提供给我的网页

这是我的settings.py

我缺少任何配置吗？

堆栈跟踪

ine 3, in <module>
    from . import views
  File "XXX:\mysite\hdfsStats\views.py",
line 5, in <module>
    from viewcreator import Builder
    ImportError: No module named 'viewcreator'

更新

目前的结构

和我的views.py

来自django.shortcuts导入渲染

# Create your views here.
from .src.viewcreator import Builder
import json
def index(request):

    a,b=Builder.buildChartJSON()
    print(json.dumps(a))  
    print(json.dumps(b))
    return render(request, 'hdfsStats/hdfscharts.html',
                  {'sourcepoints': a, 'sizepoints': b})

但现在我

from propreader import ReadProp
ImportError: No module named 'propreader'

基本上，我有四个包

viewcreator
propreader
esconnector
ping

这些包中的类根据这两个文件夹中的属性文件执行一些计算

props
resources

我把它放在与src文件夹

相同的级别

由于这些是一次性计算，我不想为这些创建模型。在这种情况下，我配置Django项目的正确方法是什么？我需要Django项目来托管一个显示我的计算结果的网页。

Answer 1

在您的INSTALLED_APPS

中

INSTALLED_APPS = [
    ...,
    'HdfsstatsConfig',
]

你的views.py中的

from .viewcreator import Builder

UPDATE，DJANGO IMPORTS

在django中有三种导入模块的方法

<强> 1。绝对导入： 从当前应用程序外部导入模块 例 来自myapp.views导入HomeView

<强> 2。明确导入： 从当前应用程序内部导入模块

第3。相对导入： 与显式导入相同，但不推荐

from models import MyModel
