Empty Gif view

Fri, 29 Jul 2011 17:02:21 -0300

Python/Django version of a view that returns an empty 1x1 gif image

from django.http import HttpResponse
code = "\x47\x49\x46\x38\x39\x61\x01\x00\x01\x00\xf0\x01\x00\xff\xff\xff\x00\x00\x00\x21\xf9\x04\x01\x0a\x00\x00\x00\x2c\x00\x00\x00\x00\x01\x00\x01\x00\x00\x02\x02\x44\x01\x00\x3b"

App Engine People Source Code Available

Mon, 20 Sep 2010 00:59:56 -0300

We started AppEnginePeople.net to learn more about GAE and hopefully create something useful. Enough devs signed up and showed interest, more then we anticipated, so we decided to open source the code of the site.

It’s available on Bitbucket and licensed under the Apache license: https://bitbucket.org/sserrano/ae-people/src

It’s one of our first app engine projects. Sorry if the code is messy. We hope it’s useful and don’t hesitate to fork and contribute patches.

thanks, Mugur Marculescu, Sebastian Serrano and Martin Riva.

Sebastian put up a statistics page up on appenginepeople.net. Check it out and see what version of the SDK devs are using and also what the countries with the most google app engine developers are.

BlobStore upload with django form validation Example

Sun, 28 Mar 2010 17:50:00 -0300

This is my current approach to handle blobstore uploads that also need a django form validation.

You can find the get_uploads helper function here: blobstore get_uploads helper function for django request

I tried to do the example as simple as possible, but complete. This may not be perfect, all comments are welcome.

Seba


#### core/models.py ####

from google.appengine.ext import blobstore
from google.appengine.ext import db

class PhotoItem(db.Model):
    name = db.StringProperty()
    photo = blobstore.BlobReferenceProperty()

#### core/forms.py ####

from django import forms

class PhotoForm(forms.Form):
    name = forms.CharField(required=True)


##### core/views.py ####

from django.core.urlresolvers import reverse
from django.http import HttpResponseRedirect
from django.shortcuts import render_to_response
from django.template import RequestContext

from google.appengine.ext import blobstore

from core.models import PhotoItem
from core.forms import PhotoForm
from core.utils import get_uploads

def upload_photo(request):
    if request.method == 'POST':
        photo_blobs = get_uploads(request, field_name="photo", populate_post=True)
        form = PhotoForm(request.POST)
        if form.is_valid() and len(photo_blobs) == 1:
            photo_item = PhotoItem(name=form.cleaned_data['name'],
                                   photo=photo_blobs[0])
            photo_item.put()
            
            return HttpResponseRedirect("/success")
        
        #ok, not valid
        if len(photo_blobs) == 0:
            #the file input is missing
            request.session['upload_error'] = "Photo is required"
            
        #save the post data in the session to be able to present errors after redirect
        request.session['upload_form_post'] = request.POST
        return HttpResponseRedirect(reverse("core.views.upload_photo"))
    elif request.session.has_key('upload_form_post'):
        form = PhotoForm(request.session['upload_form_post'])
        del request.session['upload_form_post']
    else:
        form = PhotoForm()
    
    params = {
        'upload_url': blobstore.create_upload_url(reverse("core.views.upload_photo")),
        'form': form,
        'upload_error': request.session.pop('upload_error', None)
    }
    
    return render_to_response("upload_photo.html", 
                              params,
                              RequestContext(request))

#### Example upload_photo.html ####
{% extends "base.html" %}

{% block main_content %}
    Upload Photo
    
    {% if upload_error %}
    {{ upload_error }}
    {% endif %}
    
    
        {{ form.as_ul }}
        
        
    
    
{% endblock %}

mugurm:

We’ve recently launched AppEnginePeople.net, a new directory site for Google App Engine developers, which is basically a clone of DjangoPeople.net but for app engine.

If you are interested in creating a profile just visit the site and sign in with your Google account.

tracking html5/css3 support with analytics and modernizr

Sun, 20 Dec 2009 17:28:00 -0300

You may think that html5 and css3 is going to become widespread in something akin to a geologic time scale. The truth is that many html5 and css3 features have currently widespread support.

Below, there is an small snippet to track the browser support for these advanced features for your user base, using google analytics and modernizr.

Modernizr is a small footprint javascript library that let you test the support of html5 and css3 features. With the combination of modernizr and analytics custom vars, we can track which percent of our users support a particular html5 or css3 feature.

So suppose we want to know the user base support for: sessionstorage, localstorage, canvas, fonfaces and borderradius.

Our analytics tracking code would look like:

After you append this to your site html body the results are going to appear on analytics under “visitors > custom variables”

Using a similar snippet we found that at www.wegif.com more than 80% of our users support all these features. Cool right?

For more info about how all this works, continue reading at:

appengine-storages has now a datastore backend

Mon, 07 Dec 2009 10:36:00 -0300

I just push a datastore based backend.

The code still needs more work and testing, so please not use it on any production site.

But if you are brave enough (or stupid) to do it, send me an email with your experience.

Cheers, Sebastián
