Python OpenLayerWidget&；Django管理员通过Https映射

我还是Django/Python的新手，对于这个基本问题，我深表歉意

我遇到了一个问题，地图没有显示在我的Django管理员中。我希望通过将

OpenLayersWidget

类添加到我的

forms.py

项目文件中来解决这个问题，该文件在Django文档中引用：。见下文

from django import forms
from django.contrib.gis.admin.widgets import OpenLayersWidget

class OpenLayersWidget(forms.TextInput):
    """Specifying CDN of openlayers.js in the Media class."""

     class Media:
         js = (
             'https://cdnjs.cloudflare.com/ajax/libs/openlayers/2.13.1',
         )   

我相信这太简单了

不幸的是，上述内容在https上不起作用。有什么想法吗？

试试这个：

from django.contrib.gis import admin as gis_admin

class SecureOSM(gis_admin.OSMGeoAdmin):
    openlayers_url = 'https://cdnjs.cloudflare.com/ajax/libs/openlayers/2.13.1/OpenLayers.js'

那就从这里继承吧

更新

---

从开始，https cloudflare url已成为默认url。因此，不需要再进行修补。

您需要覆盖表单

小部件。例如：

from django.contrib import admin
from django.contrib.gis.db import models
from django.contrib.gis.forms.widgets import BaseGeometryWidget

class CustomOpenLayersWidget(BaseGeometryWidget):
    template_name = 'gis/openlayers.html'

    def __init__(self, attrs=None):
        super(CustomOpenLayersWidget, self).__init__(attrs)

    class Media:
        js = (
            'https://cdnjs.cloudflare.com/ajax/libs/openlayers/2.13.1/OpenLayers.js',
            'gis/js/OLMapWidget.js',
        )


class CustomModelAdmin(admin.ModelAdmin):
    """Need to change default URL of OpenLayers"""
    formfield_overrides = {
        models.PointField: {"widget": CustomOpenLayersWidget},
        models.PointField: {"widget": CustomOpenLayersWidget},
        models.PolygonField: {"widget": CustomOpenLayersWidget},
        models.LineStringField: {"widget": CustomOpenLayersWidget},

        # Adding other models Fields if need
    }

并更改管理类

@admin.register(Position)
class PositionAdmin(CustomModelAdmin):
    pass

模型实例

class Position(models.Model):
    point = models.PointField(blank=False)

代码覆盖字段将窗口小部件组成一个新的媒体文件。这将删除http内容
http://openlayers.org/api/2.13.1/OpenLayers.js
介质的名称
