Django Admin Show Image from Imagefield

Django Admin Show Image from Imagefield

To display an image stored in a Django ImageField in the Django Admin, you can create a custom admin class and override the get_image method to generate an HTML representation of the image. Here's how you can do it:

Assuming you have a model called MyModel with an ImageField named image_field, and you want to display the image in the admin:

  • Create a custom admin class in your app's admin.py:
from django.contrib import admin from .models import MyModel class MyModelAdmin(admin.ModelAdmin): list_display = ('id', 'image_display') def image_display(self, obj): if obj.image_field: return mark_safe(f'<img src="{obj.image_field.url}" width="100" height="100" />') else: return 'No Image' image_display.short_description = 'Image Preview'

In this code:

  • We create a custom admin class MyModelAdmin that inherits from admin.ModelAdmin.

  • We define the list_display attribute to specify the fields to display in the list view of the admin.

  • We define a custom method image_display to generate the HTML for displaying the image. It checks if an image exists in the ImageField and generates an <img> tag with the image URL. We use the mark_safe function to mark the HTML as safe to render.

  • We set the short_description attribute for the image_display method to specify the column header in the admin list view.

  • Register the custom admin class in your app's admin.py:
admin.site.register(MyModel, MyModelAdmin)

Now, when you view the list view of MyModel in the Django Admin, you'll see a column called "Image Preview" with the image displayed as HTML in each row.

Make sure to replace 'image_field' with the actual name of the ImageField in your model.
