from models import WorldBorder ImportError: No module named 'models'

Question

为什么它显示错误我按照设置 GeoDjango 教程一切正确，为什么数据不会加载

型号Class：

from django.contrib.gis.db import models

class WorldBorders(models.Model):
    name = models.CharField(max_length=50)
    area = models.IntegerField()
    pop2005 = models.IntegerField('Population 2005')
    fips = models.CharField('FIPS Code', max_length=2)
    iso2 = models.CharField('2 Digit ISO', max_length=2)
    iso3 = models.CharField('3 Digit ISO', max_length=3)
    un = models.IntegerField('United Nations Code')
    region = models.IntegerField('Region Code')
    subregion = models.IntegerField('Sub-Region Code')
    lon = models.FloatField()
    lat = models.FloatField()

    # GeoDjango-specific: a geometry field (MultiPolygonField), and
    # overriding the default manager with a GeoManager instance.
    mpoly = models.MultiPolygonField()
    objects = models.GeoManager()

    class Meta:
        verbose_name_plural = "World Borders"

    # Returns the string representation of the model.
    def __unicode__(self):
        return self.name

Load.py

import os
from django.contrib.gis.utils import LayerMapping
from models import WorldBorder 

world_mapping = {
    'fips' : 'FIPS',
    'iso2' : 'ISO2',
    'iso3' : 'ISO3',
    'un' : 'UN',
    'name' : 'NAME',
    'area' : 'AREA',
    'pop2005' : 'POP2005',
    'region' : 'REGION',
    'subregion' : 'SUBREGION',
    'lon' : 'LON',
    'lat' : 'LAT',
    'mpoly' : 'MULTIPOLYGON',
}
world_shp = os.path.abspath(os.path.join(os.path.dirname(__file__), 'data', 'TM_WORLD_BORDERS-0.3.shp'))

def run(verbose=True):
    lm = LayerMapping(Pakistan, world_shp, world_mapping,transform=False, encoding='utf8')

    lm.save(strict=True, verbose=verbose)

加载数据时出错

from world import load
Traceback (most recent call last):
  File "/Users/Ismail/mainFolder/lib/python3.5/site-packages/django/core/management/commands/shell.py", line 69, in handle
    self.run_shell(shell=options['interface'])
  File "/Users/Ismail/mainFolder/lib/python3.5/site-packages/django/core/management/commands/shell.py", line 61, in run_shell
    raise ImportError
ImportError

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/Users/Ismail/mainFolder/geodjango/world/load.py", line 3, in <module>
    from models import WorldBorder
ImportError: No module named 'models'

Django官网的教程有什么问题

Answer 1

在 load.py 中，更改此行：

from models import WorldBorder # shoudn't it be WorldBorders with an s?

至：

# Assuming your appname is called 'world' and your 
# WorldBorders class is in world/models.py
from world.models import WorldBorders

上面的行可能会根据您的应用程序名称而改变。如果您的应用程序名称是 "world"，那么它应该可以工作。如果您的应用程序名称是 "ApplicationName"，则执行此操作：

from ApplicationName.models import WorldBorders

编辑：根据您的文件结构，我认为您的应用程序可能被称为 "geodjango" 所以也许可以尝试：

from geodjango.models import WorldBorders

from models import WorldBorder ImportError: No module named 'models'

from models import WorldBorder ImportError: No module named 'models'

django

postgresql
