how to give custom fields with resolver function. like image preview
Rishab08 commented
In the source code I discovered that it is possible to specify an admin_class for the reverse inline:
class FooAdmin(ReverseModelAdmin):
inline_type = 'stacked'
inline_reverse = [
{
'field_name': 'bar',
'admin_class': BarInline
}
]
And then in the BarInline:
class BarInline(admin.StackedInline):
model = Bar
readonly_fields = ["brand_logo_preview", "brand_image_preview"]
fieldsets = (
(None, {
'fields': (
('brand_logo_preview'),
('brand_image_preview'),
)
}),)
def brand_logo_preview(self, obj):
return format_html('<img src="{}" width="100" height="100" />'.format(obj.brand_logo.url))
brand_logo_preview.short_description = "logo preview"
def brand_image_preview(self, obj):
return format_html('<img src="{}" width="100" height="100" />'.format(obj.brand_image.url))
def has_delete_permission(self, request, obj=None):
return False
and hence we can add a preview
