Retrieving data while rendering form in django -

i have form fields. want display fields in form except two. 1 field data needs displayed. able form not able retrieve data db display.

model.py

class company(models.model):     status_choices=(                     ('service','service'),                     ('product','product'),     )     user=models.onetoonefield(settings.auth_user_model)     company_name=models.charfield(max_length=250)     company_address=models.charfield(max_length=250)     company_telephone=models.charfield(max_length=250,blank=true)     company_email=models.charfield(max_length=250,blank=true)     company_website=models.charfield(max_length=250,blank=true)     vat=models.charfield(max_length=250,blank=true)     service_tax=models.charfield(max_length=250,blank=true)     company_pan=models.charfield(max_length=250,blank=true)     company_bankdetails=models.charfield(max_length=250,blank=true)     invoice_type=models.charfield(max_length=250,choices=status_choices,default='service')      def __str__(self):         return 'self.user.company_name' 

forms.py

class companyeditform(forms.modelform):     class meta:         model=company         exclude = ('user','company_name',) 

views.py

@login_required def companyadd(request):     if request.method == 'post':         company_form=companyeditform(instance=request.user.company,data=request.post)         if company_form.is_valid():             new_form=company_form.save(commit=false)             new_form.save()             return render(request,'account/dashboard.html',{'section':'addcompany'})     else:         company_form=companyeditform(instance=request.user.company)     company_details=company.objects.get(user=request.user.company)     return render(request,'account/company.html',{'company_form':company_form}) 

when form displayed works planned. not getting company_name. using query company name.

company_details=company.objects.get(user=request.user.company) 

django gives following error:

cannot query "self.user.company_name": must "user" instance. 

in query company_details=company.objects.get(user=request.user.company) trying company of particular user. in statement, comparing user=request.user.company, both 2 different types (user authuser model , request.user.company company model). cannot in query.

company_details=company.objects.get(user=request.user) statement solve issue. , can company_details=request.user.company because association onetoone.
