Geodjango OGR故障问题-GDAL异常 [英] Issue with Geodjango OGR failure - GDAL Exception

问题描述

我已经成功构建了Django中的模型，但一旦添加数据并单击保存我的应用程序就会崩溃

我得到GDAL异常-OGR失败，并且它在崩溃页面中突出显示为错误的原因{{field.field}}。 以下是屏幕截图Admin view for adding data to the model

i get this right away after clicking save

有人经历过这种情况吗？有帮助吗？

谢谢

更新： 我收到此错误：

推荐答案

抱歉复制/粘贴，仅对@kiwi的回答稍加修改。我尝试向原始答案添加注释，但无法添加格式化代码。

现在，您似乎不能再安装64位版本的OSGEO4W。我安装了唯一可用的here版本，并修改了@Kiwi的答案以反映64位的缺失。我使用的是Windows 10。以下操作系统都可以正常运行。

import platform
import environ

WINDOWS = platform.system() == "Windows"

if WINDOWS:
    # the below needs to change for linux
    GDAL_LIBRARY_PATH = r'C:OSGeo4Wingdal303.dll'
    GEOS_LIBRARY_PATH = r'C:OSGeo4Wingeos_c.dll'
    OSGEO4W = r"C:OSGeo4W"
    os.environ['OSGEO4W_ROOT'] = OSGEO4W
    os.environ['GDAL_DATA'] = "C:Program FilesGDALgdal-data"  # OSGEO4W + r"sharegdal"
    os.environ['PROJ_LIB'] = OSGEO4W + r"shareproj"
    os.environ['PATH'] = OSGEO4W + r"in;" + os.environ['PATH']
