[google-appengine] How to access normal files in google App engine
Hi, I am a developing a web application which has no database but instead uses some text files(.txt) as a data store. While running on my local machine, I am able to access the folder which has these files (the folder is in my application directory). However, when I upload my application to the app engine server, I am denied permission to access this folder and files. I have tried using os.chmod to change permissions but still nothing works. What could be the problem? -Vaswani --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: How to access normal files in google App engine
Hi TIm and Konrad, Thanks for your reply. Ok, Here is the problem in a bit more detail. When I have a single (or more) text file/s in my application directory, appcfg.py uploads the files but if I have a folder inside my application directory it ignores that folder while updating unless I have specified it at static_dir in app.yaml. So my question is How can we upload a directory without specifying it in the app.yaml.

[google-appengine] Re: How to access normal files in google App engine
Hi Tim and Konrad, I understand that the ideal way to work with data is to use google data storage. But given some data constraints on my side for now, I have postponed the usage of data storage by a month. I retract my earlier statement that 'appcfg.py update' ignores some files. I probably didn't see the entire noisy messages. The files were getting uploaded but I was not allowed to access them through my script. Its actually strange if I had a small file in the application directory, I was able to access it but if I had folder (with my data files) in the application directory, the permission was denied. Anyway, I need to understand the idiosyncrasies of distributed data network in more detail. But for now I have found a not so sweet solution. I have converted each of my data files into python objects and put in individual small size files (.py) and importing them on demand. It works sweetly now but definitely not a scalable solution. But is there a ways to delete the stuff you uploaded before which you don't need anymore.

[google-appengine] Re: I've just found that the app.yaml file won't allow more than 100 handlers...
Hi Larry, I hope you are talking about the number of handlers in the handler script. Its strange that GAE does not allow more than 100 handlers. it should not be the case normally. Anyway, one way you can overcome this issue is to use regex groups to capture URL specific parameters and process the request based on the parameter. This should bring down the number of handlers as I am assuming that many of your urls would be similar.

[google-appengine] Re: Dynamically generated templates
Looking at the implementation of Django admin module might help. I don't
know exact details but for each data type (integer, String, list, date etc
it has associated interface objects that it loads to depict the data in the
correct controls.

[google-appengine] Re: database access by more than one application
Hi, Why can't you have different views for internal and external users in the same application. You can have different authentication for these views.
