Re: [google-appengine] Session User
Hi Wasfi, Use gaesessions. I am using this library and its very lightweight and robust. and can be used with webApps framework. it can be configured to use cookies, memcache and the datastore. read the advantages here : https://github.com/dound/gae-sessions and then follow the directions to install it, Installation is very simple and requires < a minute to get started . After that when the user logs in, you can store the users id or key in the session session['uid'] = value and in the subsequent classes or main handler you can check if the session['uid'] has a value. if not then the user is not logged in, and you redirect her to the login page. hope this helps :) Warm Regards Sarfaraz Farooqui -- Strong and bitter words indicate a weak cause On Sun, Dec 19, 2010 at 6:57 PM, Mohamed Wasfi wrote: > I am developing an app where I don't want to force the users to use > google authentication or openID but just sign in with their basic e- > mail addresses.

Re: [google-appengine] Re: Appengine's Turkey problem
Robert, You are right, and that is exactly the reason why GAE is blocked right now. I am afraid Kaan is a little behind the times with the YouTube ban, which has since been lifted. The most recent ban, that also affects one of the IP addresses that ghs.google.com resolves to, is related to a copyright violation by a site running on GAE or Blogger. For people who are interested (and can read Turkish), you can find a copy of the court order here: http://imgur.com/gYzPl.jpg . The IP address 74.125.43.121 is clearly visible. Kaan, Turkish authorities have reverted to blocking IP address for good now. I don't think they will change that soon, since they have seen DNS blocking does not work as they want (too easy to circumvent). About your reachability problem, I am afraid there is hardly anything Google can do about it. I know it is frustrating (I have an app or two on GAE as well) but as others have said there are ways around it: 1. You can go the reverse proxy route. Others have suggested (I am afraid I don't remember who) on this very mailing list, to use a small Linux VPS instance on RackSpace to setup a reverse proxy for your site. It seems the ping times from there to GAE are very low and the cost is only around $10 a month. I already had some Windows services hosted on an EC2 instance on AWS and set up ARR on the IIS7 server to do the reverse proxy in about 10 minutes, and haven't looked back. 2. I came upon an alternative just the other day. It appears that if you set your DNS records to point to one of alternate the IP addresses of ghs.google.com, you won't have any problems. (source: http://www.burcakcubukcu.com/2010/12/bloggerda-bulunan-alan-adl-siteme.html) Now, I haven't tried this myself, but I presume it would work for GAE as well. I suggest you setup an A record for yourself such as " redirect.example.com" with the IP address contained in the linked article and CNAME you primary site (let's say "www.example.com" to " redirect.example.com"). If, and, hopefully, when, the ban is lifted, you can change the "redirect.example.com" from an A record to a CNAME record that points to "ghs.google.com" and you will be all set. YMMV, though.

[google-appengine] NoClassDefFoundError even though the jar is in WEB-INF/lib

[google-appengine] Re: Memcache broken with Always On?
Through trial and error, I figured out that I was using it wrong. With
the JCache API, you have to make sure that you "create" and register
the cache once on each GAE instance (JVM) before you can just do a
getCache(String cachename) on it within that JVM.
So even in code that only reads from the cache, you need to make sure
the full cache initialization is performed or has already been done
somewhere in that JVM instance. For example:
cache = CacheManager.getInstance().getCache("testcache");
if (cache == null) {
cache = CacheManager.getInstance().getCacheFactory()
.createCache(Collections.emptyMap()); //Or whatever
properties are required
CacheManager.getInstance().registerCache("testcache", cache);
}
This is the same code you use to create and register the global cache
in the first place. For new instances, it appears to just create the
required link to the existing global cache. Makes sense to me now
since you don't know which instance or reader/writer code will be hit
the first time a cache comes into play.
After invoking the code above in my readers, I now see the cache and
entries in it being shared globally.
Thanks,
Tom

[google-appengine] Re: from google.appengine.ext.webapp import template
Hello The templates should work like before. I too had this failure with importing template when upgrading to SDK 1.4 and solved it going through the error message seeing it originated from some third party library I had added myself to my project. I removed that library and again things worked. If you post or more closely investigate the error log it may show that your problem/solution is the result of some library conflict.

[google-appengine] doubt about TOS regarding betting related app
I want to make an application related to gambling and I am not sure if it would break the terms of service or not. In principle, the TOS prohibit gambling content (letter f of "Prohibited content" under "Google AppEngine Program Policies"). The application would be similar to a blog on sports betting, with tips and advice for people who enjoy betting in sports competitions. Users will not be able to make bets using my application, but they would receive explicit advise on which bets are more profitable than others. Would that break the terms of service? I am thinking of GAE to develop the application but I am not sure if it could be rejected by Google, because clearly it is not an app that enables gambling but it will help bettors in their decissions.

[google-appengine] Re: my app has been "disabled"
the most attractive feature of google's appengine is free to start. but when your project becomes large, you may found a better platform to deploy your project. i don't think google appengine can be used for large projects because there are so many dependencies on the app engine platform. even the data is stored in a way very hard to manipulate(upload, download, delete, modify). I would like to define the app engine as a new blog platform which users can do more customization on it. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
