    <p>I am writing small django internet store and I have encountered a problem. Namely, I would like print list of the products (I need pruduct id) and also some form to buy them on the same page.</p> <pre><code>def order(request): if request.method == 'POST': form = OrderForm(request.POST) if form.is_valid(): # POST data processing return HttpResponseRedirect('/cart/') else: form = OrderForm() # here I would like to also use product_id from POST to generate products # that have such id return render(request, 'order.html', { 'form': form, 'products': products, }) </code></pre> <p>But when I wrongly submit form, OrderForm() is called and then I lose my id. Any hints how to solve this problem (maybe keep somewhere that id)? </p> <p>Edit: my store is used to rent some products on given time and adding product to cart means that I create new object rent that store information when product has been reserved by user</p> <p>Model:</p> <pre><code>class Rent(models.Model): product = models.ForeignKey(Product) paid = models.BooleanField() begin_date = models.DateField(auto_now=False) end_date = models.DateField(auto_now=False) begin_hour = models.IntegerField(max_length=2, default=00) end_hour = models.IntegerField(max_length=2, default=24) </code></pre> <p>And OrderForm</p> <pre><code>class OrderForm(forms.Form): begin_date = forms.DateField(label='date', required=True, widget=extras.widgets.SelectDateWidget(years=range(2013, 2015))) end_date = forms.DateField(required=True, initial=datetime.date.today, widget=extras.widgets.SelectDateWidget(years=range(2013, 2015))) begin_hour = forms.ChoiceField(required=True, choices=((str(x), x) for x in range(0, 25))) end_hour = forms.ChoiceField(required=True, choices=(((str(x)), x) for x in range(0, 25))) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
