Re: Nested Model Issue

[mohamed habib]

You can use a signal to ensure that a profile is created for each user.
Make sure all the fields in your Profile model are nullable:

```
class Profile(models.Model):

GENDER_CHOICES = (
  ('male', 'Male'),
  ('female', 'Female')
)
user = models.ForeignKey(User,on_delete=models.CASCADE,related_name
= 'usermodel')
permanent_address_city =
models.ForeignKey(Address,on_delete=models.CASCADE,related_name =
'permanent_address_city', null=True, blank=True)
phone_number = models.PositiveIntegerField(, null=True, blank=True)
gender = models.CharField(max_length = 5,choices = GENDER_CHOICES,
null=True, blank=True)
profile_pic = models.ImageField(upload_to='profile_pic',default =
'default.jpg', null=True, blank=True)
created_at = models.DateField(auto_now_add = True, null=True, blank=True)
updated_at = models.DateField(auto_now = True, null=True, blank=True)

```

use signal within your models.py to create a blank profile every time
a User object is created:


```

from django.db.models.signals import post_save

from django.dispatch import receiver
@receiver(post_save, sender=settings.AUTH_USER_MODEL)def
create_user_profile(sender, instance, created, **kwargs):
if created:
UserProfile.objects.create(user=instance)

```

Now you can create an Update profile view to update the user based on
the fields he has placed in the instance using your serialiser. You
can have a separate view to create an address object. The User Profile
update view can take the ID of an address and attach that address to
the user.

Re:

[Andrew C.]

I suppose in a view, you can write something along these lines:

import json
from os import path
from django.conf import settings

def index(request):
if request.method == ‘POST’:
 form = YourForm(request.POST)
 if form.is_valid():
 field1 = form.cleaned_data.get(‘field1_from_form’)
 # write your JSON here
 # Follow this tutorial to write your json:
https://stackabuse.com/reading-and-writing-json-to-a-file-in-python/
 # Instead of dumping your file into a txt like they did in the
first example, do this:
 with open(path.join(settings.MEDIA_ROOT, “ajsonfile.json”),
“w+”) as outfile:
   json.dump(data, outfile)
  return redirect(request.get_absolute_uri())
elif request.method == “GET”:
form = YourForm()
return render(request, “index.html”, {‘form’: form}


I forgot the import statement for the redirect

Re: How to build users tagging system in my comment textarea.

[Andrew C.]

You would probably need AJAX calls. I think there’s a package called
Django-autocompletelite which can help you with this. So, in your HTML, you
can use use AJAX to see when a user types the @ character with a single
letter and then show a box with some usernames with that.
