Answer 1

You can do something like this:

 import requests
 import json


class Model(model.Model):
    url=models.URLField()
    price=models.FloatField()

    def save(self, *args, **kwargs):
        resp = request.gets(self.url)
        #assuming that json response looks like this: {'price': 2000} 
        resp_str = resp.content.decode()
        resp_dict = json.loads(resp_str)
        self.price = resp_dict.get('price')
        super().save(*args, **kwargs)

note: the code has not been verified, but this is enough to give a general idea of ​​the continuation.

models.py
class Testone(models.Model):
    url = models.URLField()
    price = models.DecimalField(max_digits=30,decimal_places=5)

admin.py
@admin.register(Testone)

class PriceAdmin(admin.ModelAdmin):
    fields = ['url']
    def save_model(self, request, obj, form, change):
        obj.price = poang.ikea_ru(request.POST['url'])['price'] # calls external function w/ the requests data. 
#function returns dict that why i use ['price'] to get a value from the dict
        super(PriceAdmin,self).save_model(request, obj, form, change)
