Re: [appengine-java] How to upload pics in appengine java

2010-03-13 Thread Pavel Byles 
AFAIK almost any file can be apart of the docs that you upload (images, css,
html, js, jsp, ico). I haven't had any trouble uploading images.

Are you talking about accepting images from an input form? In that case you
can store them as a blob type in the datastore.

Hope this helps

 Hi Pavel,

 I too use a setup very similar to yours, with both GWT and appengine
 projects in same workspace.
 However I have also managed to setup my GWT environment so that I can
 debug!
 What I basically do is have GWT servlets which act as proxies to the
 actual appengine handlers.
 In these servlets I just forward the call to corresponding appengine
 handler and send back the response received.
 It works great and really saves a lot of time.

Sure,
you can store anything in your datastore. I don't see why not.

I am also using the django framework.
Just set up your models and you should be good to go.

 Basically I do not want to store the user session in my user datastore
 table. The user table simply contains user info like first name, last
 name, userid etc and user validation will be using this table. Also I
 am using django framework.

[google-appengine] Re: How to do this?

2009-03-03 Thread Pavel Byles 

arnie,
Specifically, if you want your users to use Google's account
credendials you can use the google.appengine.api module and check the
users class.

You can send non-logged in users to the Google Account login for your
application like this
users.create_login_url(self.request.uri))
This will create a cookie in the users' browser that will allow them
to stay logged in

Sow wrt your question, i am not sure that you need to store the users
session information in your datastore for this purpose.

This is all explained in the Getting Started guide:
http://code.google.com/appengine/docs/python/gettingstarted/usingusers.html

Hope this helps.

 Any idea?

[google-appengine] GqlQuery to JSON

2009-02-18 Thread Pavel Byles 
Hello all,
I would like to get JSON from the result of a GqlQuery.
I've already seen this post  GqlQuery *object* and
JSONhttp://groups.google.com/group/google-appengine/browse_thread/thread/634e7b9a2e584dd3/2d89b9e9db7aba56?lnk=gstq=GqlQuery+object+and+JSON+#2d89b9e9db7aba56
 but it doesn't really help.

I understand that I cannot use serializers.serialize.

Is there another easy way to do this without using simplejson?

It's ok. Got it.
Used django.utils.simplejson rather than the regular simplejson module
