Re: RelatedObjectDoesNotExist: User has no vendor

vendor = Vendor.objects.get(created_by=request.user)
you have to pick vendor like this

thank you Lalit for you respond

I have changed this line

 vendor = request.user.vendor 

to 

user = vendor.created_by 

Now i'm getting this error

NameError at /maduka/vendor_admin/

name 'vendor' is not defined

coming because of `vendor = request.user.vendor`
you have attached user to vendor so you can access user from vendor by doing

`user = vendor.created_by` but you can not access vendor from user

Hi Every one! I 'm looking for help.

I'm working with  a multi vendor website using django. But there is an issue that I have vendor object vendor but it says User has no vendor. Why is this happening and how may I solve this?

MY model

from django.contrib.auth.models import User  from django.db import models    class Vendor(models.Model):      name = models.CharField(max_length=255)      created_at = models.DateTimeField(auto_now_add=True)      created_by = models.OneToOneField(User, related_name='vendor', on_delete=models.CASCADE)    class Meta:      ordering = ['name']    def __str__(self):      return self.name

My View    def become_vendor(request):      if request.method == 'POST':          form = UserCreationForm(request.POST)          if form.is_valid():              user = form.save()              login(request, user)              vendor = Vendor.objects.create(name=user.username, created_by=user)              return redirect('frontpage')        else:          form = UserCreationForm()      return render(request, 'vendor/become_vendor.html', {'form': form})    @login_required  def vendor_admin(request):      vendor = request.user.vendor      return render(request, 'vendor/vendor_admin.html', {'vendor': vendor})

Error i'm getting
