在Django管理员内联中显示缩略图 [英] Display thumbnail in Django admin inline

问题描述

我是Django的新手，正在尝试更改嵌入式图像在管理面板中的显示方式。我可以在每个当前上方添加预览标签并显示缩略图吗？

i'm new to Django and trying to change how inline images are presented in the admin panel. Can I add a Preview tag above each 'Currently' to and show thumbnail?

推荐答案

经过大量挖掘，我设法做到了。不幸的是，我找不到我使用的来源（过多的标签，太多的标签无法使用。）。因此，我们的想法是创建一个图像小部件，并附加一些html脚本。

I managed to do it after a lot of digging. Unfortunately I couldn't find the source I used (too many tabs, too many didn't work..) . So the idea was to create an Image Widget, that appends some html script.

from django.contrib.admin.widgets import AdminFileWidget

class AdminImageWidget(AdminFileWidget):
    def render(self, name, value, attrs=None):
        output = []
        if value and getattr(value, "url", None):
            image_url = value.url
            file_name = str(value)
            output.append(u' <a href="%s" target="_blank"><img src="%s" alt="%s" width="150" height="150"  style="object-fit: cover;"/></a> %s ' % \
                (image_url, image_url, file_name, _('')))
        output.append(super(AdminFileWidget, self).render(name, value, attrs))
        return mark_safe(u''.join(output))


class CollectionImageInline(admin.TabularInline):
    formfield_overrides = {models.ImageField: {'widget': AdminImageWidget}}

结果：（无论此问题，我已将管理主题更改为默认主题）

the result : (I changed admin theme to default regardless to this issue)
