<p>I am looking for how to do validation on Google App Engine and I have found only how to do it using Django framework. Ok Django approach is ok but if I have one form and this form have data from few tables what then??? I can not do it like this:</p> <pre><code>class Item(db.Model): name = db.StringProperty() quantity = db.IntegerProperty(default=1) target_price = db.FloatProperty() priority = db.StringProperty(default='Medium',choices=[ 'High', 'Medium', 'Low']) entry_time = db.DateTimeProperty(auto_now_add=True) added_by = db.UserProperty() class ItemForm(djangoforms.ModelForm): class Meta: model = Item exclude = ['added_by'] class MainPage(webapp.RequestHandler): def get(self): self.response.out.write('<html><body>' '<form method="POST" ' 'action="/">' '<table>') # This generates our shopping list form and writes it in the response self.response.out.write(ItemForm()) self.response.out.write('</table>' '<input type="submit">' '</form></body></html>') def post(self): data = ItemForm(data=self.request.POST) if data.is_valid(): # Save the data, and redirect to the view page entity = data.save(commit=False) entity.added_by = users.get_current_user() entity.put() self.redirect('/items.html') else: # Reprint the form self.response.out.write('<html><body>' '<form method="POST" ' 'action="/">' '<table>') self.response.out.write(data) self.response.out.write('</table>' '<input type="submit">' '</form></body></html>') </code></pre> <p>Is any easy way to validate form which contain data from few tables or I have to code it alone?</p>

Guidance

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.
