Associating users with models django

I have a lot of models in model.py -

class Portfolio(models.Model):
  company = models.TextField(null=True)
  volume = models.IntegerField(blank=True)
  date = models.DateField(null=True)
  isin = models.TextField(null=True)

class Endday(models.Model):
  company = models.TextField(null=True)
  isin = models.TextField(null=True)
  eop = models.TextField(max_length=100000)

class Results(models.Model):
  companies = models.TextField(default=0)
  dates = models.DateField(auto_now_add=False)
  eodp = models.FloatField(null=True)
  volume = models.IntegerField(null=True)

class Sectors(models.Model):
  sector_mc = models.TextField(null=True)

class Insector(models.Model):
  foundation = models.ForeignKey(Sectors, null=True)
  name = models.TextField(null=True)
  value = models.FloatField(default=0)

class AreaLineChart(models.Model):
  foundation = models.ForeignKey(CompanyForLineCharts, null=True)
  date = models.DateField(auto_now_add=False)
  price = models.FloatField(null=True)

  class Meta:
    ordering = ['date']

I have more such models but as you can see from this snippet, they are not in any way related to any user.

Now I want to relate them to a particular user. In the views too, I was not classifying data per user in any way.

I make users from django admin with username and password and also generate a token for those users from admin. I can authenticate via username and password but from there I know I'd need to use permissions but how is what I do not know. Also, I have serializers that are associated to these models, I know I'd have to use permissions there too but again, I don't know how to. As much as I understand it has to be in someway like this-

@api_view(['GET'])
def searched_company_ohlc(request):
  if request.method == 'GET':

  // User.objects.get('username'=some_user) 
  //I guess.

  qs = SearchedCompanyOHLC.objects.all()
  serializer = SearchedCompanyOHLCSerializer(qs, many=True)
  return Response(serializer.data)

Also, I'm using angularJS at the front-end that POSTS username and password on a view with POST decorator to verify the credentials. Where to go from here?

in your models.py you can relate user like this for example

from django.contrib.auth.models import  User, Group
class Portfolio(models.Model):
 owner = models.ForeignKey(User,verbose_name = 'User',related_name='portfolios')
 company = models.TextField(null=True)
 volume = models.IntegerField(blank=True)
 date = models.DateField(null=True)
 isin = models.TextField(null=True)

This has nothing to do with permissions.

If you want to associate your model with a user, use a ForeignKey to the user model.
