[google-appengine] I Need A Push In The Right Direction - Basic Design

[RRRaney]

Hello,

I am trying to get started using AppEngine.
I have been reading many of the articles about implementing an MVP
design pattern,
I think that I can handle most of this once I get started with my
basic design.

I would like to create a site with three pages (all done with HTML
pages).

HomePage.html
ApplicationPage.html
ContactMePage.html

I have all of these built and am happy with the way that they look and
have the Navigation working just fine.

On the ApplicationPage I would like to include a Launch Button (this
is where I will take over and build my Application with its menus and
different data Views).

With all of the examples that I have been looking at the Button that
gets the ball rolling is on the first and only page.

How can I get MyHandler for the Launch Button on the ApplicationPage?

A little push would be a great help.

I believe that I can take care of the rest after I get the basic right
correct.

Eventually I would probably be adding AnotherApplicationPage and so
on.

Thanks,

Raney

Good Morning,

Thankyou for the fast response.
I will take a look at the example.

I had just come back to put the address of the site so people could
see what I would like, I do not always explain very well.

[google-appengine] Too many "Warning: Request was aborted after waiting too long..." under not so high load

[Will]

My site doesn't have too much traffic, but now and then I see this warning:

Request was aborted after waiting too long to attempt to service your
request. This may happen sporadically when the App Engine serving
cluster is under unexpectedly high or uneven load. If you see this
message frequently, please contact the App Engine team.


Just half an hour ago, I saw one DeadlineExceededError and one
TransactionFailedError, immediately followed by 5 warnings mentioned above,
within roughly 30 seconds, when my application was trying to insert some
text data into datastore, in one plain put().

The load I saw for that particular url was about 13 requests per minute.
Well, this kind of load shouldn't cause datastore to choke in a way as I've
seen, in my expectation.

This problem results in data loss in my app and then bad
customer-experiences.

Should I expect this is the current capability of datastore/GAE? Or are
there any guidelines for minimizing this problem?

My app id is 'qyingweb'.

Thanks,

Will

[dflorey]

>From what I can tell this error occurs quite frequently when the load
of the app changes.
If you have very low load for a couple of minutes and then get
multiple requests, you'll most likely get some 500ers.
App engine works ok if the load is constant over a longer period of
time.
(At least no requests over a long period of time work fine ;-)

Hi Will,
Don't now if this helps, the error request is stored in the error log,
from there you can restore you eventual data loss.

Re: [google-appengine] How to make this

Thanks for your advice, but I'm in fact just interested in that if there
exists a way to make this by a software or some pieces of code, you know, we
may do this by simulate HTTP requests or things like that, so I just want to
find out a correct way to realize this.

Re: [google-appengine] Too many "Warning: Request was aborted after waiting too long..." under not so high load

[Robert Kluin]

Hi Will,
  Here are a few of my thoughts and suggestions.

  The datastore will occasionally have spikes in latency / error
rates, for reasons outside of your apps control.  Your best bet for
dealing with periods of increased latency is to optimize your
requests.  It sounds like you have a good handle on what your app is
doing, but a little addition review never hurts -- use Appstats to
profile your RPCs.  Appstats is great for making sure no unexpected
calls are being made and for identifying spots that need some
optimization.

  It also sounds like you might need to handle error's a little
differently.  Maybe you should catch those errors and defer writing
the entity using the task-queue, if possible.  And/Or return feedback
to the client that the save failed; if the client is a browser at
least let the user know the save failed so their data is not
_unexpectedly_ missing.

  Also, what are your apps cold start times like?  If your app takes a
long time to bring up a new instance that could cause problems.  There
are several things you could try, such as minimizing start-up time
imports.

I do not think there is an official groups API.

You might ask in some other group too, maybe there is a groups-group.  ;)

[google-appengine] Re: 500 Server Error while deploying the application

[James Benton]

I am in a similar boat. I cannot access the dashboards (500 Server
Error) and cannot deploy my application, just stalls on "Initiating
Update" for ages then I get


Error 401: --- begin server output ---

Must authenticate first.


--- end server output ---


If deploy fails you might need to 'rollback' manually.


The "Make Symlinks..." menu option can help with command-line work.


*** appcfg.py has finished with exit code 1 ***


Only thing I can think of that might make it an issue is the fact I've
been deploying it numerous times, with different versions today.

[google-appengine] What is "latest" for in version URL

[efleming969]

I've read that past versions of appengine made minor version numbers
available via the URL (ie. major.minor.app-id.appspot.com).  This is
no longer available and I understand why, but what's the purpose of
having the "latest" indication in the URL now that minor versions are
no longer available?

Thanks

[google-appengine] Re: Can't deploy app > 503 error

[Edward Sarker]

I think the app engine API is down. I spent the better half of the
last 2 hours trying to debug my code, app engine and everything else.
i had no other system to test on so i didn't know it wasn't just my
laptop with the issue.

[google-appengine] Re: Blobstore upload is failing with mysterious "signature verification failed" redirect

[Gijs (Cloudwise)]

I got the same problems using the blobstore. All I want is uploading
files to the blobstore using AJAX(-like) functionallity. I tried
http://valums.com/ajax-upload/ and http://jquery.malsup.com/form/#file-upload
both javascript plugings for jQuery. All works fine in the dev
environment, but in production it simply doesn't work. While digging
in the response I found this "signature verification failed" message.
Anyone any idea?

[google-appengine] Can't move down then up the directory tree for inserting of html files with {% include %}

[Brian]

Thanks for the help.

I'm using Python 2.5 and Django Template 1.1 on app engine

I can't seem to move down the dir tree for inserting of html files
using  {% include "file" %} statement
Works just fine to any where up the tree, i can go up 3,4 levels just
fine, but can not go down even 1 {% include "../LOGO.html" %}


Sample dir structure:

root/lib/LOGO.html  (1 level down then 1 level up )
root/LOGO.html  (1 level down)
root/main/home.html <--tried: {% include "../LOGO.html" %} ,{% include
"root/lib/LOGO.html" %} , {% include "/root/lib/logo.html" %}
root/main/start.py

I changed TEMPLATE_DIRS setting 20 ways.

Thanks.

[google-appengine] webapp2 Import Error

[Scott Lewis]

Hi,

I'm new to web development, and particularly python development, so
please forgive any obvious mistakes that I've made. Any help would be
greatly appreciated.

I'm trying to use webapp-improved (http://code.google.com/p/webapp-
improved/) on my local Windows Vista system. The results I'm getting
are:

Traceback (most recent call last):
  File "C:\Program Files (x86)\Google\google_appengine\google\appengine
\tools\dev_appserver.py", line 3211, in _HandleRequest
self._Dispatch(dispatcher, self.rfile, outfile, env_dict)
  File "C:\Program Files (x86)\Google\google_appengine\google\appengine
\tools\dev_appserver.py", line 3154, in _Dispatch
base_env_dict=env_dict)

  File "C:\Program Files (x86)\Google\google_appengine\google\appengine
\tools\dev_appserver.py", line 2314, in ExecuteCGI
reset_modules = exec_script(handler_path, cgi_path, hook)
  File "C:\Program Files (x86)\Google\google_appengine\google\appengine
\tools\dev_appserver.py", line 2210, in ExecuteOrImportScript
exec module_code in script_module.__dict__
  File "C:\Users\slewis\Desktop\helloworld\helloworld.py", line 1, in

import webapp2 as webapp
ImportError: No module named webapp2

My python file looks like:

import webapp2 as webapp

class HelloWorldHandler(webapp.RequestHandler):
def get(self):
self.response.out.write('Hello, World!')

app = webapp.WSGIApplication([
(r'/', HelloWorldHandler),
], debug=True)

def main():
app.run()

if __name__ == '__main__':
main()

I started development using python 2.7 and got this issue, then from
reading on this group that 2.5 was preferable, I switched to that, but
nothing has changed. I was able to run the google app engine tutorial
without errors, so I believe something is wrong with how I installed
webapp2. (I uncompressed it in a separate directory, then navigated
there in the command line and executed 'python setup.py install' and
there were no errors on the install.)

Again, any help would be greatly appreciated! Thank you.

[google-appengine] incoming bandwidth of urlfetch when content_was_truncated is true

[tanchuhan]

hi, everyone.
i code this to fetch something:

#fetch
try:
src_response = urlfetch.Fetch(self.url, self.request.body,
self.method,
  headers, True, False)
except urlfetch.InvalidURLError, ex:
msg = "invalid url: %s" % self.url
logging.error(msg)
self.__error(400, msg)
return False
except urlfetch.DownloadError, ex:
msg = "download error: %s" % ex
logging.exception(msg)
self.__error(503, msg)
return False

as you see, i set "allow_truncated=True", when fetch some file large
than 1M(such as 12M), gae just give me 1M, but when i look at the
"Quota Details", the "Incoming bandwidth" had increase about 10M,
sometime it raise an Exception:
OverQuotaError: The API call urlfetch.Fetch() required more quota than
is available.

it means that gae count 12M "Incoming bandwidth" but just give me 1M
in fact, i cann't get the file size before fetch, so it's impossible
to set "range" header before fetch. i think gae shouldn't count the
true file size in "Incoming bandwith".

maybe someone will suggest me send a "HEAD" request before fetch, but
the content-type is unknown, i don't think it's a good solution.

Yes I see what you're saying. Map Reduce would bring over the whole entity
even though it isn't needed and would consume more CPU in fetching the
entity not just the key. Seems almost like it would be nice to have an
option of Map Reduce only handing off keys and leaving out the entity.

In the Python MR libs, there is a DatastoreKeyInputReader input
reader.  It looks like that is what's used to iterate over the
entities.

[Stephen Johnson]

In the Java SDK I think one could subclass the DatastoreRecordReader to do a
keys only query and return null for the entity value and use this class in
lieu of the normal DatastoreRecordReader when needed. Probably similar in
Python.

Raney, what is it exactly youneed assistance with?  Do you just want
the "Launch" button to launch into a new page?  or are you requesting
assistance in building the associated logic for the "Application"?  To
have your button just open up a new page you could either use
javascript onClick, or make it a submit button with target of the
desired page.

I assume you have checked out the getting started guide already, but
since no one linked it yet: 
http://code.google.com/appengine/docs/python/gettingstarted/
this will take you from nothing to "hello world".

[aaron]

Hi there,

I have gone through that tutorial, but as I mentioned i did miss the
key points, so right now I'm brushing up on python and am just
starting off with using python in conjuction with app engine.

Resources I've found helpful so far (I left out the ones that could
have been better):

For Python (my first port of call in this mission and all very good)

Learn Python the Hard Way
http://docs.python.org/tutorial/
http://diveintopython.org/ -
Python for Software design by Allen Downey

For google apps

Oreilly - Programming Google Apps Engine (just working through this
now)
As soon as I've been through this book I'll have a look at the google
apps getting started guide and docs again.

[google-appengine] Re: I Need A Push In The Right Direction - Basic Design

[RRRaney]

Hello Ben,

I have a "Lauch" button that is not on the main page.

I would like to listen for the clickevent of this button and then
enter my application if it happens.

I do not think that I will have any problem with the code of the
"Launched Application" just how to get there is my problem.

If I have a "Submit" button on the HomePage, as the default AppEngine
builds as default, that is accessable with the RootPanel, there is not
ant problem.

How can I listen for a clickevent on the ApplicationPage.html (not the
main page)?

When I am on the HomePage.html, the only thing that I want to happen
is navagation within the Web-Site pages.
When I am on the ContactMePage.html, the only thing that I want to
happen is navagation within the Web-Site pages
When I am on the ApplicationPage.html I would like to listen for the
"Launched" clickevent and then enter my AppEngine code or just
navigate to the other pages code.

I hope this makes sense.

Thanks,

Raney

Re: [google-appengine] What is "latest" for in version URL

[Ikai Lan (Google)]

Good catch. Right now it exists for backwards compatibility, but you don't
actually need it to access versions as of one of the recent releases. You
can get to a version at:

http://version.appid.appspot.com

We'll have to update our docs to reflect the change.

Re: [google-appengine] Re: I Need A Push In The Right Direction - Basic Design

[Robert Kluin]

Hi Raney,
  Maybe I am misunderstanding, but I would say (based on the
terminology you're using) you might want to find yourself an HTML
tutorial.

  Here is some basic information on how you can make a button open a link:

[google-appengine] Is percent encoding valid in URL to the images service (from get_serving_url)?

[Chris Copeland]

Hi folks, I am trying to determine if this is a Google bug or not.

I have images stored in the blobstore and use get_serving_url() to get URLs
to them.  These URLs always have a least one equals sign (=).  If the sign
is encoded as %3D, then the images service returns 404.

Example:

Works:
http://lh4.ggpht.com/n6Tg_8uEu-nS_5ugZ4L5FpFwZ4koEozGfgpo3B84hjxcGRENdX31xzW_r7lD2u7lEd99hxn7jiRULxKA4D8=s400
404:
http://lh4.ggpht.com/n6Tg_8uEu-nS_5ugZ4L5FpFwZ4koEozGfgpo3B84hjxcGRENdX31xzW_r7lD2u7lEd99hxn7jiRULxKA4D8%3Ds400

The URL is getting encoded by Facebook so I have no control over it.  It
seems like a Google bug since %3D is the correct escape for =.  Is there
anything I'm missing?

[google-appengine] Re: I Need A Push In The Right Direction - Basic Design

[RRRaney]

Hello Robert,

I do not seem to be explaining myself very well, as usual.

I think that I have a fair understanding of HTML basics.

I have coded, complied and deployed three pages to an AppEngine
Address:

https://rrrsystems-demo-vamv05bnm5.appspot.com
https://rrrsystems-demo-vamv05bnm5.appspot.com/HomePage.html
https://rrrsystems-demo-vamv05bnm5.appspot.com/TrainingOpenings.html
https://rrrsystems-demo-vamv05bnm5.appspot.com/ContactInformation.html

All are behaving as I would like.

I would like to listen for the “Launch:” button on the
TrainigOpenings.html Page.
When this button is clicked I would like to enter my AppEngine code.

I have seen on the GreetingApplication generated by the Eclipse Goolge
Web Application how to go about this with the “Submit” button on the
home page.(this shows me all kinds of great information about my
ServerInfo and the User-Agent)

I would like to get things going with the “Launch” button on the:
https://rrrsystems-demo-vamv05bnm5.appspot.com/TrainingOpenings.html

I do not want the “Launch” button to redirect to another AppEngine
Address as I will need to access some of the data in other
Applications (RegisteredUser data, HostAgency data, SCSEPStaff data,
SCSEPParticipant data)……

After I get this down I will probably add things for the Hosts( allow
them to do things like change the phone, address).

Hope this helps,
Thanks,

Raney

[google-appengine] Re: I Need A Push In The Right Direction - Basic Design

[RRRaney]

Hello Robert,

I think that I have the basics of HTML down ( you can view the
source).

I have a harder time explaining what it is that I am trying to do.

I have defined and coded the three HTML pages and deployed them to:
http://rrrsystems-demo-vamv05bnm5.appspot.com

The Site and the HTML pages work just fine.
I can navigate and all is well.

When I am on the page,
http://rrrsystems-demo-vamv05bnm5.appspot.com/TrainingOpenings.html
I would like to listen for the click event of the "Launch" button on
this page and then enter my AppEngine code.
Actually go to the "TrainingOpenings: Application. (Not a seperate
Site, I will need data from here in the other Applications)

If I look at the GreetingApplication that is created by the AppEngine
Web Application, I get there by the "Submit" button on the home page.

I would like to get there with the "Launch" button on:
http://rrrsystems-demo-vamv05bnm5.appspot.com/TrainingOpenings.html

This is not the home page.
I cannot seem to get the onLoadModule to listen for other HTML page
events, I think that it is something simple, just cant see it.

Does this explain what I would like to do any better?

Thanks,
Raney

Re: [google-appengine] Re: I Need A Push In The Right Direction - Basic Design

[Robert Kluin]

Hi Raney,
  I may be showing my own ignorance here, but I don't think I've ever
heard of "onLoadModule"?   You might want to mention if you are using
Python or Java, and if you are using anything like GWT, Flash / Flex,
Silverlight, or a Java applet.

  The typically way to 'enter' your application code is to have a URL
for it.  So you might map the URL
"http://rrrsystems-demo-vamv05bnm5.appspot.com/trainingapp/"; to your
Python application or servlet.  Your users will not be leaving your
site, just going to another area of your application.  When your users
click the Launch button it will take them to your training
application.

Transferring the failed uploads to task queue sounds very attractive for my

You've got a few good options.  Check out:

Although, I generally find it easier to write my own 'services' for
importing data.
