我已经在django中构建了模型，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，它在崩溃页面中突出显示“{{ field.field }}”作为错误的原因。这是Admin view for adding data to the model的屏幕截图

i get this right away after clicking save

有没有人经历过这个？有什么帮助吗？

谢谢

更新:我得到了这个错误：

对于复制/粘贴和仅略微修改@Kiwi的答案，我深表歉意。我尝试在原始答案中添加注释，但无法添加格式化代码。

现在看来，您不能再安装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Windows10。下面的一切都运行得很好。

代码语言：javascript
复制
import platform
import environ

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

if WINDOWS:
    # the below needs to change for linux
    GDAL_LIBRARY_PATH = r'C:\OSGeo4W\bin\gdal303.dll'
    GEOS_LIBRARY_PATH = r'C:\OSGeo4W\bin\geos_c.dll'
    OSGEO4W = r"C:\OSGeo4W"
    os.environ['OSGEO4W_ROOT'] = OSGEO4W
    os.environ['GDAL_DATA'] = "C:\Program Files\GDAL\gdal-data"  # OSGEO4W + r"\share\gdal"
    os.environ['PROJ_LIB'] = OSGEO4W + r"\share\proj"
    os.environ['PATH'] = OSGEO4W + r"\bin;" + os.environ['PATH']

if os.name == 'nt':
    import platform
    OSGEO4W = r"C:\OSGeo4W"
    if '64' in platform.architecture()[0]:
        OSGEO4W += "64"
    assert os.path.isdir(OSGEO4W), "Directory does not exist: " + OSGEO4W
    os.environ['OSGEO4W_ROOT'] = OSGEO4W
    os.environ['GDAL_DATA'] = "C:\Program Files\GDAL\gdal-data" #OSGEO4W + r"\share\gdal"
    os.environ['PROJ_LIB'] = OSGEO4W + r"\share\proj"
    os.environ['PATH'] = OSGEO4W + r"\bin;" + os.environ['PATH']

问题是这段代码在geodjango上强制执行其中定义的路径，所以即使您设置了系统变量，这段代码仍然会控制系统变量。

如果任何人对OGR有疑问，请毫不犹豫地发表意见
