python - Updating fields of model using forms and views on Django 1.7 -


in models.py product model is

class product(models.model):     productname = models.charfield(max_length=20, default='1',blank=false,null=false, primary_key = true)     userphone = models.charfield(max_length=20, default='1')     userid = models.foreignkey(account, default='1',null=true)     productdesc = models.textfield(blank=false,null=false, default='1')     productcategory = models.foreignkey(category, null=false, default='1')     productprice = models.decimalfield(default='0',blank=false,null=false, max_digits=6, decimal_places=2)     picture = models.imagefield(upload_to='product_images', blank=true, null=true, default='1')      def __unicode__(self):         return self.productname

the form have add new products is,

class productform(forms.modelform):     productname = forms.charfield(label='product name')     productcategory = forms.modelchoicefield(label='category', queryset=category.objects.all())     productdesc = forms.charfield(label='product description', widget=forms.textarea)     productprice = forms.decimalfield(label='expected price')     userphone = forms.charfield(label='phone number')     picture = forms.imagefield(label='upload picture')      class meta:         model = product         fields = ('productname', 'productcategory', 'productdesc', 'productprice', 'userphone', 'picture',)       def clean_productname(self):         productname = self.cleaned_data['productname']         try:             product.objects.get(productname=productname)         except product.doesnotexist:             return productname         raise forms.validationerror("a product under name exits. rename product.")      def clean_productcategory(self):         productcategory = self.cleaned_data['productcategory']      def clean_productdesc(self):         productdesc = self.cleaned_data['productdesc']      def clean_productprice(self):         productprice = self.cleaned_data['productprice']      def clean_userphone(self):         userphone = self.cleaned_data['userphone']      def clean_picture(self):         picture = self.cleaned_data['picture']

and take form input, have in views.py file

@login_required(login_url='/accounts/login/')    def newproduct(request):     if(request.method =='post'):         product_form = productform(request.post, request.files)         if product_form.is_valid():             product = product_form.save(commit=true)             product.save()         else:             print product_form.errors      else:         product_form = productform()     return render(request, 'market/postad.html', {'product_form':product_form} )

i want update userid field of product model user_id of logged in user. how go doing that? 

request.user.id

might give me id of logged in user. how associate product being entered database? (i using mysql database)

my auth_user_model isn't configured account. there way without configuring it?

my account model is

class account(models.model):     user = models.onetoonefield(user)

i imported user django.contrib.auth.models

in views.py (if auth_user_model configured account)

@login_required(login_url='/accounts/login/', template_name='market/postad.html')    def newproduct(request):     product_form = productform(request.post or none, request.files or none)     if(request.method =='post'):         if product_form.is_valid():             product = product_form.save(commit=false)             product.userid = account.objects.get_or_create(user=request.user)             product.save()         else:             print product_form.errors     return render(request, template_name, {'product_form':product_form} )
