How to find Only the logged in user content in django? - django

Question

class User(auth.models.User,auth.models.PermissionsMixin):
def __str__(self):
return '#{}'.format(self.username)
class placement(models.Model):
name=models.CharField(max_length=150, blank=True, null=True)
ad_space=models.CharField(max_length=100, blank=False, null=False)
PID_TYPE = (
('FN','FORMAT_NATIVE'),
('FNB','FORMAT_NATIVE_BANNER'),
('FI','FORMAT_INTERSTITIAL'),
('FB','FORMAT_BANNER'),
('FMR','FORMAT_MEDIUM,RECT'),
('FRV','FORMAT_REWARDED_VIDEO'),
)
format = models.CharField(max_length=3,choices = PID_TYPE,default = 'FN',blank=False, null=False)
pid=models.CharField( max_length=50,default='',blank=False, null=False)
cpm=models.IntegerField(default=0,blank=False, null=False)
ADS_TYPE=(
('FB','FACEBOOK'),
('G','GOOGLE'),
)
source=models.CharField(max_length=2,choices=ADS_TYPE,default='FB',blank=False, null=False)
comments=models.TextField(default='',blank=False, null=False)
objects=models.Manager()
def __str__(self):
return self.name
def get_absolute_url(self):
return reverse("dashapp:disp")`
Now what should i do to only get only the logged in user content to be displayed on the template.As currently all the stored data is being fetched . That is logged out user for data is being displayed.
I'm Basically a beginner so i dont have any advance idea about this.
Full explanation are needed.

Answer 1

You can access the logged in user like this:
{% if user.is_authenticated %}
<p>Welcome, {{ user.username }}. Thanks for logging in.</p>
{% else %}
<p>Welcome, new user. Please log in.</p>
{% endif %}
In django, the logged in user has an attribute is_authenticated which is a boolean value. If user is logged in, it gives True, else False.
Update
If you meant to see the placement model values in template for current user, you need make some relations with the user to placement. So you need to update the placement model:
class placement(models.Model):
user = models.ForeignKey(User, null=True, default=None)
.... # rest of the fields
And save user info to placement in views:
class SomeCreateView(CreateView):
...
def form_valid(self, form):
form.instance.user = User.objects.get(id = self.request.user.id)
return super(SomeCreateView, self).form_valid(form)
and get placements of a user in view like this:
placements = placement.objects.filter(user=request.user)
