[google-appengine] Re: How to select a single word in stringproperty?
谢谢回复。
我问的是字符串属性部分匹配的问题。按你的方法，只能匹配开头。需要匹配中间的时候，比如在前例里，查找含有 ccc 的对象，该怎么做？
HOW to select the entity with "ccc" in strprop then?

[google-appengine] Re: Images API still limited to 1MB
Indeed the entire API is limited to 1MB, but the point of discussion I'd like to make is that for data-related API calls like the datastore and memcache, it's easy to come up with hardware/implementation constraints that would warrant such a limit, and there are usually relatively simple ways to work around them. For a processing API call like an image API call, there should be no dependence on BigTable or any sort of clustering, so the limit seems a little arbitrary, especially in light of the request limit increase to 10MB which does not seem to have any value for image requests. I'm honestly hoping it's just an oversight that will be fixed in the short term. In the interim, using an external image API seems to be the best solution indeed. Right now, I'm looking into the Imageshack API which seems to offer enough functionality, but can you go into how you use the Picasa API? It seems to be very well suited to importing a user's photos, but to upload and manage photos as a website would require using ClientLogin, and since ClientLogin uses a captcha, it doesn't work well on app engine. Or at least, that's what's written in the App Engine Data API docs. Thanks.

[google-appengine] errors with django.
I need to know how the urls work.
I would get errors on all 3 pages plus the admin.
here is the error:
: Caught an exception
while rendering: Reverse for 'settings.contact-consultation-request'
with arguments '()' and keyword arguments '{}' not found. Original
Traceback (most recent call last): File "/home/aaron/websites/

source = (, (894, 932))
when I change the url.py and take out contact.views out of url.py.
then this error would disappear.
yet the forms would still not work.
I would get this error when I submit the forms:
'str' object is not callable
that's it. I don't know whats the problem. I asked in django's group
and not many people had any idea what's wrong.
Some told me to try this and that but it didn't work.
does anyone here know what could be the problem?

[google-appengine] Retrieving Large Query Sets Containing Inequality Operators
I have the model:
class Record(db.Model):
date = db.DateProperty()
Over 1000 Record instances may contain the same date value. The
instances are also not created in the order of their dates.
I'm trying to query all instances whose date is within a given range.
I need to be able to query sets larger than the default max of 1000.
I was thinking of doing something like:
Record.all().filter('date >', startDate).filter('date <', endDate)
But this would limit me at most to the first 1000 records. How would I
get the next 1000 records, maintaining the range query? I can't use
the last date value from the previous query as the startDate for the
next query, since there's no guarantee that the date value has
changed. For example, I could have 2000 instances with the date
2008-1-1, so the first and second query sets have identical filter
parameters.
Intuitively, I could accomplish this by simply filtering on the
previous key value (e.g. .filter('key >', lastKeyValue)).
Unfortunately, App Engine currently prohibits filtering with
inequality operators on more than one property.
Am I correct in understanding that there's essentially no way to query
all instances within a specific date range, due to this limitation?
This issue keeps coming up for me, and has been a huge deal-breaker in
a lot of potential projects I've been working on for App Engine. Any
advice on how I could work around it would be appreciated.
Chris

There is no way to disable GAE except deleting the app.yaml file, and I don't think it will work. Your apps need at least one domain for GAE( if you ever create one ). So you can try add an new domain, delete the old one, then add it again. 2009/4/19 Chris L > > I set up App Engine with a Google Apps domain one year ago.

Well, but I don't care it, my application allows the same ID, I just need it

If you want keep a unique ID, the best way is set its key_name, and try

[google-appengine] Google Apps account - can't enable HTTPS or remove App Engine from domain
I set up App Engine with a Google Apps domain one year ago. Now I am informed that "You must re-install this application to enable secure access for your users." Problem is, if I try to disable the App Engine service, nothing happens, even after hours of waiting. I have App Engine enabled for the naked domain, which might be part of the problem, and I can't remove that either. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

If two requests want to create an M() they will get the same ID.

Very cool, but I don't know if this will solve the 'practical lock in' problem for GAE python. It may be hard to find a hosting provider that offers django along with long-running java processes. Still, GAE-J developers now have a reasonable alternative and maybe some of your efforts can be applied to an all python version for BDB (or zodb).

According to the google maps team, we have to expect atleast some [small] amounts of datastore errors. Is there anyway to get the SDK to throw these errors, so I can better test how my application responds when a specific query is denied (i.e make sure the right code kicks in and handles the error?)

[google-appengine] becoming an app administrator with google apps account
I'm trying to send email on GAE with my Google Apps primary email as the "From" email address. So I need to add that email address (which is i...@bigriddles.com) as an Administrator for my app. However, I'm having trouble doing this. I add that email as an adminstrator and receive the invite email, which offers two options, as follows: 1. "sign in with your Google Account " - this doesn't work because even though i...@bigriddles.com is the admininstrator email for the Google Apps account, Google for some reason doesn't recognize this as a "Google Account". So it gives me a "wrong username or password" error when I try to confirm the invitation by signing in with this. 2. "if i...@bigriddles.com is a Google Apps Account, you can sign in and accept or decline this invitation here" - The problem here is that when I try to use this option, it asks for me to confirm the account with a cell phone number. And of course I've already confirmed another account with my cell phone number, so it won't let me do this. Any suggestions?

[google-appengine] Google's ext.webapp.template module
What practically happens when this directive is executed?
*
from google.appengine.ext.webapp import template
*
Is this importing Django or something else?
The reason why I ask this is I'm a newbie to GAE and want to walk
before I can run...on the surface Django looks powerful but there are
so many moving parts in it that it hurts my brain.
Anyone have an example of how to iterate over a list using Google's
vanilla templating framework...
for instance this is a snippet from a Django html template...
{% for message in messages %}
{{ message.title }}
Anyway I could replicate this functionality without Django and if so
how?
Thanks much.

[google-appengine] Re: How to select a single word in stringproperty?
You can read this document:
http://code.google.com/appengine/docs/python/datastore/queriesandindexes.html
Give you a sample code:
class M(db.Model):
s = db.StringProperty()
class H(webapp.RequestHandler):
def get(self):
M(s='aaa bbb ccc ddd').put()
M(s='eee ddd ccc fff').put()
M(s='eee').put()
M(s='eee ').put()
M(s='eef').put()
entities = M.all().filter('s >= ', 'eee').filter('s <= ', u'eee' +
u'\ufffd').fetch(10)
# u'\ufffd' is the largest possible Unicode character
for entity in entities:
self.response.out.write(entity.s + '')
Result:
eee ddd ccc fff
eee
eee

[google-appengine] Re: app.yaml - how to serve ALL files as they are..?
I'd think this would work (but I haven't tried it): - url: / static_dir: static Note: this requires all of your site files to be in a subdirectory of your application, since for a static_dir directive you need to specify a relative directory. I'm not sure if "static_dir: ." would work. Try it yourself; I'm not personally interested in using app engine for non-webapp static websites. Seems like a waste.

I know in principle how to redirect.

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] Images API still limited to 1MB
When App Engine raised its request size limit from 1MB to 10MB, it seemed like we would finally be able to use it for an image sharing website as while reasonably sized digital camera images over 1MB are very likely, it'd take an extremely professional camera image to break the 10MB limit, which seemed like an acceptable limit to place on a user's file uploads since those users are probably knowledgeable enough to resize the images themselves anyways. API calls were still limited to 1MB, and as the examples listed on the blog post were memcache and datastore, it seemed to make sense since App Engine is probably still designed to place a 1MB limit on its datastore entries. This seemed like it'd be ok since it should be possible to use the images API to resize any input images to less than 1MB before storing them in the datastore, completely acceptable for our task. However, after trying this and looking into some server errors, it seems the images API is also limited to 1MB input files (which fits with the 1MB limit on API calls, the fact just didn't register at first). At least, that's how I'm interpreting the RequestTooLargeError (The request to API call images.Transform() was too large) I get when submitting a 1.5MB file. Is the limit on the images API by design/constraint? I imagine image API calls aren't split across computers in a cluster or anything and are run in place, with possibly some temp memory that's cleared immediately, which makes having a limit smaller than the request size seem a little strange to me. A 1MB limit on image files makes it hard to support user submitted image uploads in a practical setting. I know it's possible to split the image over datastore entries just to store them, but we also need to be able to resize them to generate thumbnails, etc. And if anyone's come up with a workaround splitting the input file into parts to resize in parts, it'd be nice to hear.

[google-appengine] Re: Performance issues
Thanks for the suggestion. I'll try #3 as an first approach and see where that takes me (and look forward to #5). I think app-engine- patch has a main() declared, and I assume the app is getting cached as a result, but I'm not sure if that's the case. Re the file caching idea, I don't understand the present environment enough to do more than guess about how this might be done, so this is just brainstorming. I assume that there are two different factors that are going into the longer request times that I've been seeing in my own case. There's the zipimporter call, which decompresses the Django 1.0 archive that I keep in a subdirectory of my app. I imagine this takes a while each time it happens, and it might account for much of the request time. Since zipimporter isn't called with every request and some requests are pretty quick, I assume in those instances I'm hitting a server on which the needed python symbols were resolved during a previous request. Hence the application was probably memory resident, and the zipimporter call wasn't needed. In other instances it's possible that the application had to be reloaded from the network, which might account any time above that necessary for the zipimporter call. If I remember correctly, the reason the Django files are being archived is that there's a 1000 file limit on what can be uploaded (in a single upload?). Using an archive instead of an uncompressed directory is a way to get around this limit. What I had in mind in the postscript was something like a distributed, shared memory for the cloud as a whole that doesn't know or care about the actual data that is being shared (python or Java files) or where it comes from (application developers). If 1000 applications request a file often enough (e.g., a core Django library file), it would be pushed out to the servers in such a way that symbols could be loaded by the python interpreter from memory rather than from a file on disk or over the network. We would know how often a file was being requested by taking a strong cryptographic checksum of the contents of each file in an application the first time an open() system call is called on the file after a new version of the application has been uploaded. Perhaps such an open() call would happen during a python import. Once the checksum has been obtained, the usage of the file could then be tracked across applications and across requests, and it could be checked against a large table of checksums on which statistics are being maintained. Although some of this might happen during the request, I think a lot of it could be deferred until later. Since we're working at a pretty low level, hopefully it wouldn't matter if the original source of a file was an archive rather than an uncompressed directory; one issue, though, is that the uncompressed files from an archive will obviously be (much) larger than the archive itself and will require more memory. The problem with making use of the archive itself is that the zipimporter call seems to cost a lot, but perhaps it is small compared to a network call. In this setup, if 1000 applications use a common subset of Django files (0.96, 1.0 or whatever), the total server memory across the cloud devoted to those files at any given time wouldn't necessarily be less than in the current setup, since some or all of the subset will have been pushed out. But it wouldn't be necessary to push out a single application in its entirety as often, since some of the files might already be in memory. I'm not sure how this would affect other applications, e.g., how much it would reduce the need to recycle memory currently being used for other applications when there is a new request. But hopefully it would result in a more efficient use of existing resources. There would be an incentive for people to use the same libraries so that their applications would be more responsive, and perhaps a pricing signal could be devised that would encourage this. There would be a need to ensure that the files that are understood to be shared really are the same files, so that someone isn't able to inject a malicious file that is then used by a number of other applications. If A uploads a common file that is profiled and then gets pushed out and B's application is to make use of it, it would be important for A's version of the file to be the same as B's version, so that B's application isn't compromised. I was thinking that a strong cryptographic checksum might be adequate for this, but I'm sure there are challenges I'm not aware of. Something like MD5 probably wouldn't be suitable, since I understand there are ways to make different files that have the same MD5 hash. Perhaps including a check of the file size would be enough. Computation time needed to derive the hash would be an important factor. You guys are obviously facing a pretty challenging problem. Best of luck in this regard.
