从模型导入WorldBorder导入错误：没有名为模块“模型”

Question

为什么它显示的错误，我跟着来设置GeoDjango内置教程一切是正确的，所以数据不会加载

模型类：

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) 

错误加载数据

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'

什么是错在Django网站的教程

Answer 1

在load.py，改变这一行：

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

到：

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

线以上可根据什么改变你应用程序名称是。如果你的应用程序名称是“世界”，那么它应该工作。如果你的应用程序名称是“应用程序名”，那么这样做：

from ApplicationName.models import WorldBorders 

编辑：根据您的文件结构，我想你的应用程序可能被称为“GeoDjango内置”，所以也许尝试：

from geodjango.models import WorldBorders
