Not sure what is going on exactly. Maybe a local problem... though the rest of the web works. Anyway: https://appengine.google.com/ Now works for me. As do my appspot related URLS: http://hogbaysoftware.appspot.com/ http://simpletextws.appspot.com/ But I'm still seeing a sitewide 500 error when I try to access my sites through their normal URLS: http://www.simpletext.ws/ http://www.hogbaysoftware.com/ Same error message: - Error: Server Error The server encountered an error and could not complete your request.

[google-appengine] Re: Sitewide 500 errors
This appears to now be a local problem, at least for me. I'm on OS X using Safari. If I change to Firefox then my sites load. I cleared cache on Safari and still saw the problem. Then I did Reset Safari and that appears to have fixed the problem. Sorry for sounding the alarms when the problem was local.

[google-appengine] Re: Sitewide 500 errors
Actually your site (www.bijout.com) loads for me in Safari, and I found that my own site loads if I switch to a different user on my computer. Is something in cookies / cache triggering this? I think it must be related to that. I said that resetting Safari fixed the problem for me... and it did. But now I see the problem again after logging into my Google Apps email account. So problem still not fixed for me. Jesse -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Sitewide 500 errors
Me too -- clearing cookies fixed the problem. Kinda strange, but whatever I think the problem is bigger then that... at least for me. I can fix the problem by clearning cookies, but the problem also comes back after a few minutes. Maybe after I've logged into one of my google accounts.

[google-appengine] javax.net.ssl.SSLHandshakeException

[google-appengine] Re: Is class Body(db.Model): ok?
It sometimes takes a while for new entity types to be reflected in the Admin Console. Are the entities showing up now? No, I'm still seeing the same errors in the console. My app ID is hogbaytaskpaper. I'm doing a migration, extracting a big TextProperty from my Document model into a separate Body model. I'd like to complete this (and delete the existing TextProperty attribute from my Document model), but I'm worried since Body still isn't showing up in my console.

[google-appengine] Re: Is class Body(db.Model): ok?
Sorry, I misread your original post. The issue here is that the only property theBodyentity has is a TextProperty, which is not indexed. It's a known bug (we're working on it!) that entities with no indexed properties do not show up in the production Admin Console. Your data is there, it's just that the admin console can't see it. If it's important that it show up in the admin console, you can add a dummy indexed property to the Model and re-put existing entities to add it. Nick, Ahhh thanks for your response. I'll go ahead with things, I don't really care about it showing up in the console app, I was just worried that there might be something wrong elsewhere. Glad to know there isn't.

I've just added a new model class to my app that's defined like this: class Body(db.Model): content = db.TextProperty() It seems to be working fine in my server code, but for some reason it doesn't show up in the list of entities shown by the App Engine Console Data Viewer.

Have you added any Body entities to your datastore? Sometimes I get HTTP 500 errors in the console viewer for models with no existing entities. Yes I've added a lot, and they seem to be working, I just don't see them in the console. I also have an Includes ancestors index that's serving Body entities.

[google-appengine] Re: Model design for wiki like index pages
One thing that comes to mind first is to use key_name for that purpose. Perhaps you can use pagenames as key_name when storing pages, you can use keys_only query for rendering the Index page. Thanks, I hadn't taken the time to learn about key queries, and they look like a great tool to have. But unfortunately I don't think they work for my case. The problem is that for my index page I actually want more information then just the page name, I need two properties actually, I need the page name, and it's version. I can't really store that information as a named key, because the version will be changing regularly. I guess at this point I'm just not going to worry about it until I see real world performance problems. And I'll try to address those with memcache. But long term I would (if it makes sense in the datastore architecture) like the option to select a subset of an entities properties. Does anyone know if this is already a feature request that I can vote on, or should I make a new request... and how best to word it. I'm not sure how efficient/possible it would be to read out a subset of properties from the datastore blob. But maybe a condition would be that the specified properties need to be stored in at least one index? If someone who knows a bit more about the possibilities of the datastore can direct me in the right direction, I'll write the request.

[google-appengine] Model design for wiki like index pages
I have a wiki like app. The basic model is a page which has title(StringProperty) and a body (TextProperty) properties. It all seems to work well, but I'm not sure how well my model will scale. The problem I see is that I want to have an Index page, which lists all other pages. My concern is when a model object is loaded in GAE all property fields are also loaded in from the store at the same time. That would seem to post a problem with my app on index pages, because it would mean when someone visits the index page both the title (which I want) and body (which I don't need) for all pages would need to be loaded from the store. Loading the body in this case seems wasteful, and possibly very problematic performance wise on a site with many pages. My questions: 1. Is this a problem that other people are worrying about, should I worry about it? I could solve the problem by dividing my page model into two separate models... on that contained the title and a reference to another model which would contain page body. That should make the index page scale, but it complicates the rest of the app. I'd prefer to avoid that rout if possible. 2. Is there, or is there a future possibility to specify that certain fields in a model are lazy load, not fetched and returned in the initial query?

[google-appengine] Is the new User.user_id() property guaranteed to exist?
From the docs it seems that it is. But on the dev server User.user_id () returns None.

[google-appengine] https access through naked domain
I'm hosting my website (www.hogbaysoftware.com) through Google Apps and on Google App engine. Previously this site was hosted on another service that allowed naked domains, so I have many incoming links of the form http://hogbaysoftware.com. To fix these links I enabled forwarding on Godaddy.com and generally that fixed the problem. Now most naked domains get forwarded to www.hogbaysoftware.com. The problem is that I also have some secure https incoming links such as: https://hogbaysoftware.com/store And unfortunately these (naked domain links using https) aren't getting properly forwarded. When I enter the above link in my browser the browser just says Loading... for a long time and then responds with: Safari can’t open the page “https://hogbaysoftware.com/store” because the server where this page is located isn’t responding. Has anyone else noticed this problem. Can anyone recommend a solution?

[google-appengine] Re: https access through naked domain
Nick, The problem here is likely that GoDaddy aren't serving redirects over port 443 (the HTTPS port). Even if they were, users would get dire warnings about broken SSL certificates. Thanks for your quick response. The only solution is to find someone who will serve 302 redirects and host your SSL certificate (someone you trust, naturally). I'm not sure if there are any commercial services that will do that. It's fairly straightforward to set up in Apache, if you have your own server somewhere, though. Thanks for your help. I guess I'll just ignore the problem for now... that's why I love Google App Engine so much, because I don't have to deal with servers, apache, SSL certificates... A! I don't want to go back to that world :) But I'll explain the problem to Godaddy and see if they have a suggestion. Thanks again for your answer.

Be sure to check the 'request' logs. If your app returned a non-200 response code but didn't log an error, it will not show up in the 'error' logs. Thanks! I didn't realize that. I'm guessing that it also won't log a response for 3XX errors? At least it seems not to. Does anyone know exactly what response codes report errors and what ones do not? Looking at my logs the error frequency reported in the dashboard seems to correspond to 401 (Unauthorized) responses from that URL. I'm guessing that must be it then.

[google-appengine] Google Accounts RSS feed authentication
I'm using the built in users authentication on my website. I really like it's simplicity, and I like the fact that many potential users will already have a Google Account, so they can use my site without having to create a new account. But I've run into a problem. I'd like to have protected (protected by users Google Account login) rss feeds on my site. But since (to my knowledge) the Google Account api authentication process (http:// tinyurl.com/atbzwk) isn't standard and supported in RSS readers I don't think it's possible to do this. Couple of thoughts. First suggestions? Is there some workaround? And if not: - It would be great if api login for google app engine apps could follow some standard. Or if not create a new standard that's appropriate. - Or if that's not possible, at least document the current api authentication process somewhere on google site to make it a bit easier to find and official.

[google-appengine] Transaction collision AND AttributeError: 'Document' object has no attribute '_key_name'
I'm running into a frequent
AttributeError: 'Document' object has no attribute '_key_name'
Error when I try to delete multiple documents from the datastore (same
entity group). This error only occurs when the delete request first
runs into a Transaction collision. So for example I send these three
delete requests in quick succession:
DELETE /v1/documents/1-62?version=0
DELETE /v1/documents/1-1071?version=0
DELETE /v1/documents/1-64?version=0
The first two requests work fine. But in this case the third dumps a
Transaction collision and then a no attribute '_key_name stack trace
in the logs, and the delete fails to take place:

The problem doesn't seem related to the documents server state. Right
after that above failure I sent the same delete request again, and it
worked fine that time. So I'm 99 percent sure that the cause is the
transaction collision, but I'm not sure how to resolve it. Quite
possibly I'm doing something wrong in my code, here's when my delete
method looks like. If you need to see more code I'd be happy to
provide the @require_document code to. Just let me know.

After a bit more playing and reading I think the route of my problem is that I've designed things so that there is a bit to much contention in my entity group, I probably shouldn't be running into failed transactions so much in the first place. My basic design is that each user account marks the root of an entity group. And the users documents are children of that group. This seems like a reasonable design to me, but the problem is that my sync client hits the group pretty hard. If the user deletes all their documents locally, then the sync client fires of a separate DELETE request for each document, all at the same time, and I think that's the root of the problem. So I guess I need to write a batch delete handler... or make the client send the DELETE requests in sequence, instead of all at once. Let me know if I'm missing a better way... still getting used to web programming.

[google-appengine] best transaction and then memcache.delete pattern
What's the best pattern for using transactions together with memcache.delete? def txn(): ... get, put some entities Option 1: do memcache.delete here db.run_in_transaction(txn) Option 2: do memcache.delete here Option 1 is to run do it in the last line(s) of the txn() function. Option 2 is to do it right after the successful call to run_in_transaction(). Option 2 feels a bit more correct, but Option 1 is convenient because I have easy access to the various model properties there. Are both options OK, or do that have different behavior that could cause problems?

[google-appengine] How to map URL containing commas to webapp handler
This is a pretty basic question, but I can't seem to figure it out.
I'd like to map a URL that contains commas to a handler using the
webapp framework. Something like this:
application = webapp.WSGIApplication([
('/versions/1,2', VersionsDifferenceHandler),
], debug=True)
But that just gives me a 404. I've tried escaping the comma with a
single or double \, but that doesn't help. Can someone give me a hint
as to what I'm doing wrong?
Thanks,
Jesse

[google-appengine] Re: Creating a short unique URL for an entity
You could use the id instead of the key, key().id, then you can get it back with just DocModel.get_by_id(id) You should be able to go straight to the doc without the parent account id /doc/12345 I'm not sure you can guarantee id uniqueness across your whole data store, but it should be unique for any given model? Thanks for your reply. If ID is unique across a particular kind that's good enough for me... I don't need a globally unique ID across all entity kinds, just across a specific entity kind. I'm still curious if anyone knows for sure if these IDs are unique across the entire store, or just unique across a given entity group. Very possibly I'm just missing it, but I can't seem to find this in the documentation. That would make me assume that they are globally unique, but then it is unclear to me what Key() has the parent entity group encoded in it for entities that are part of a given group.

[google-appengine] Creating a short unique URL for an entity
I'm relatively new to web programming, so don't feel back about
telling me the obvious :)
I have a simple model consisting of Account entities that can own many
document entities. I'd like to create a short as possible, globally
unique URL scheme that I can use to access any document. For testing
right now I'm just using the documents .key() in the URL. So for
example my urls look something like this:
/documents/
ag13cml0ZXJvb20tY29tchwLEgdBY2NvdW50GH4MCxIIRG9jdW1lbnQYiQEM
But that's really long. I'm now trying to figure out the easiest way
to make it shorter. One option that I'm considering is to just put the
account id and document id in the URL separated by a dash like this:
/documents/126-137
And then I can reconstruct the Key like this:
db.Key.from_path('Account', account_key, 'Document', document_key)
I haven't actually tried this yet... but I think it should work?
My goal is a unique, short, permanent URL for every document in the
system. If I'm going about this the wrong way or doing something dumb
please let me know.
Thanks,
Jesse

[google-appengine] http HEAD responds with 405 in webapp framework
The webapp framework is fairly strict about http head requests. I'm not a web framework expert, but I think most web frameworks will implement head in terms of http GET if an explicit HEAD handler is not implemented. But webapp seems to require that head is explicit implemented in your handler or else it will return a 405 error. I would like HEAD to work on my site, but I don't really want to go and add special HEAD handlers to each of my controllers. This brings up two questions: 1. Would it make sense to modify the webapp framework so that HEAD requests fall back on GET if HEAD isn't implemented? 2. Related, in my app I've just added this default controller: class HEADHandler(webapp.RequestHandler): def head(self, *args): return self.get(*args) And I make all my other controllers inherit from it. This seems to work as desired, my controllers now correctly respond to HEAD requests. Is this an OK implementation, or can it cause problems that I'm not thinking about?

[google-appengine] Google App Engine setup sequence...
I have an app hosted on google app engine at hogbaysoftware.appspot.com. I also have my domain hogbaysoftware.com setup with google apps. I'd like to connect the two so that I can access my app engine application at www.hogbaysoftware.com. A few months ago I set the same system up for another domain of mine (taskpaper.com), and it's working great. But it doesn't seem to be working, or at least I'm not getting any feedback when I try to set it up for my hogbaysoftware.com domain. I've tried setting things up from both ends (the app engine console) and also from the google apps dashboard. But in both cases nothing seems to happen after I go through the setup process. For example from the google apps dashboard I: 1. Click add more services 2. Enter my app id hogbaysoftware for the Google App Engine service. 3. Click the Add it now button. 4. Accept the agreement, type www for the web address. 5. Click Continue to setup url 6. Add a CNAME pair of www ghs.google.com in my DNS records 7. Click the i've completed these steps button. I don't get any errors, but after pressing that button I'm just sent back to the google apps dashboard without any confirmation message. The google app engine service isn't listed in my dashboard of services. And if I go to my google app engine console, and look at the versions view there's also no indication that any domains are being setup. What should I do next. I've just changed all my DNS records, and I'm worried that my site will go dead when people find my DNS pointing to ghs.google.com, but with nothing setup on the google side. Thanks for any ideas on what to do next. Jesse --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.
