    <p>I have a problem with how to do validation on GAE. I have read many tutorials and I prepared django form and I wanted to validate it but I dont see eny error messages in my web page code and I dont see any errors when the values are bad. </p> <pre><code>import cgi import os from google.appengine.ext.webapp import template from google.appengine.ext import webapp from google.appengine.ext.webapp.util import run_wsgi_app from google.appengine.api import users from google.appengine.ext import db from google.appengine.ext.db import djangoforms from django import newforms as forms class SurveyForm(forms.Form): occupations_choices = ( ('0', "Choose one..."), ('1', "Undergraduate student"), ('2', "Postgraduate student (MSc)"), ('3', "Postgraduate student (PhD)"), ('4', "Lab assistant"), ('5', "Technician"), ('6', "Lecturer"), ('7', "Other" ) ) howreach_choices = ( ('0', "Choose one..."), ('1', "Typed the URL directly"), ('2', "Site is bookmarked"), ('3', "A search engine"), ('4', "A link from another site"), ('5', "From a book"), ('6', "Other") ) boxes_choices = ( ("des", "Website Design"), ("svr", "Web Server Administration"), ("com", "Electronic Commerce"), ("mkt", "Web Marketing/Advertising"), ("edu", "Web-Related Education") ) range_choice = ( ('1', '1'), ('2', '2'), ('3', '3'), ('4', '4'), ('5', '5') ) name = forms.CharField(label='Enter your name', max_length=50, required=True) email = forms.EmailField(label='Your email address') occupations = forms.ChoiceField(choices=occupations_choices, label='What is your occupation?') howreach = forms.ChoiceField(choices=howreach_choices, label='How did you reach this site?') # radio buttons 1-5 rating = forms.ChoiceField(choices=range_choice , label='How would you rate the content of this site?', widget=forms.RadioSelect) boxes = forms.ChoiceField(choices=boxes_choices, label='Are you involved in any of the following? (check all that apply)', widget=forms.CheckboxSelectMultiple) comment = forms.CharField(label=('Any other comments?'), widget=forms.Textarea(attrs={'cols': 40, 'rows': 10}), required=False) class MainHandler(webapp.RequestHandler): def get(self): user = users.get_current_user() if user: url = users.create_logout_url(self.request.uri) url_linktext = 'Logout' userName = user.nickname() else: url = users.create_login_url(self.request.uri) url_linktext = 'Login' userName = '' template_values = { 'url' : url, 'url_linktext' : url_linktext, 'userName' : userName, 'form' : SurveyForm(), } path = os.path.join(os.path.dirname(__file__), 'index.html') self.response.out.write(template.render(path, template_values)) def post(self): user = users.get_current_user() if user: url = users.create_logout_url(self.request.uri) url_linktext = 'Logout' userName = user.nickname() #self.response.out.write(index.html) else: url = users.create_login_url(self.request.uri) url_linktext = 'Login' userName = '' template_values = { 'url' : url, 'url_linktext' : url_linktext, 'userName' : userName, 'form' : SurveyForm(), } form = SurveyForm(self.request.POST) if self.request.get('submit') == 'Submit the Form': if form.is_valid(): self.response.out.write("Poprawne dane") else: form = SurveyForm() template_values['form']=form path = os.path.join(os.path.dirname(__file__), 'index.html') self.response.out.write(template.render(path, template_values)) else: path = os.path.join(os.path.dirname(__file__), 'index.html') self.response.out.write(template.render(path, template_values)) application = webapp.WSGIApplication([('/', MainHandler)], debug=True) def main(): run_wsgi_app(application) if __name__ == '__main__': main() </code></pre> <p>Do You know maybe any tutorial - good tutorial how to do it? My index.html:</p> <pre><code> &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;&lt;head&gt;&lt;title&gt;Survey&lt;/title&gt; &lt;/head&gt; &lt;body&gt; {% if userName %} You are loged in like: {{ userName }} &lt;a href="{{ url }}"&gt;{{ url_linktext }} &lt;/a&gt; &lt;hr&gt;&lt;br/&gt;&lt;b&gt;Fill in the form: &lt;/b&gt;&lt;br/&gt; &lt;form action="/" method="Post"&gt; {{ form.as_p() }} &lt;input type="submit" name="submit" value="Submit the Form"&gt; &lt;/form&gt; {% else %} Please, log in: &lt;a href="{{ url }}"&gt;{{ url_linktext }}&lt;/a&gt; {% endif %} &lt;/body&gt; &lt;/html&gt; </code></pre> <p>How to do it does the validation started to show me errors? And be like "normal validation"? I thought when I will use the framework it will be much more easier and faster for me but I spent 2 days and it is still not working :/ I could write my own validation in this time :/</p> <p>Can You help me? </p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
