Is there any chance to add link to change page of a Foreign key object next to 'raw_id_fields' in django admin? I use raw_id_fields to reduce number of queries to mysql. I could edit or add a foreign key object when I didn't use raw_id_fields.
How to do it with raw_id_fields?
@AntoinePinsard, I've tried the second solution. The field 'Edit My FK' was created but there is nothing except for a hyphen.
That's my modeladmin.
class FlatAdmin(admin.ModelAdmin):
inlines = [NeedInline]
readonly_fields = ('flat_house_edit_link',)
raw_id_fields = ('flat_house',)
list_display = ('show_date','show_block','show_house','show_rooms','show_price','show_stage')
list_filter = ('flat_house__house_block','flat_rooms')
search_fields = ('flat_house__id',)
field = ['flat_house','flat_house_edit_link','flat_owner','flat_price','flat_rooms','flat_total_sq','flat_life_sq','flat_kitchen_sq','flat_floors']
def flat_house_edit_link(self, instance):
if instance:
fk_id = instance.user_id
else:
fk_id = None
if fk_id:
opts = instance._meta.get_field('flat_house').rel.model._meta
related_url = reverse(
'admin:{}_{}_change/?_to_field=id&_popup=1'.format(
opts.ha,
opts.house,
),
args=[fk_id],
)
return format_html(
'<a target=_blank href="{}">Go!</a>', related_url)
else:
return "No related object"
flat_house_edit_link.short_description = "Change house"
admin.site.register(Flat,FlatAdmin)
