Django:在管理界面中显示图像 [英] Django: Display image in admin interface

问题描述

我定义了一个包含图像链接的模型.有没有办法在模型项目列表中显示图像?我的模型看起来像这样:

I've defined a model which contains a link an image. Is there a way to display the image in the model items list? My model looks like this:

class Article(models.Model):
    url = models.CharField(max_length = 200, unique = True)
    title = models.CharField(max_length = 500)
    img = models.CharField(max_length = 100) # Contains path to image

    def __unicode__(self):
       return u"%s" %title

有没有办法把图片和标题一起显示?

Is there a way to display the image together with title?

推荐答案

您可以创建一个具有其他名称的模型实例方法，允许为其输出使用 HTML 标记并将此方法添加为列表字段.下面是一个例子:

You can create a model instance method with another name, allow HTML tags for its output and add this method as a list field. Here is an example:

首先添加一个返回包含图像的 HTML 的新方法:

First add a new method returning the HTML for the image inclusion:

class Article(models.Model):
    ...
    def admin_image(self):
        return '<img src="%s"/>' % self.img
    admin_image.allow_tags = True

然后将此方法添加到列表中:

Then add this method to the list:

class ArticleAdmin(admin.ModelAdmin):    
    ...
    list_display = ('url', 'title', 'admin_image')
