No, there is no stacktrace in the logs only the warning. Also I have tried passing the stream as payload but I get an error there as well. Its stacktrace is: File /base/data/home/apps/s~app-id/1.357014326405166801/applications/ abc/controllers/xyz.py:download, line 384, in report_download File /base/data/home/apps/s~app-id/1.357014326405166801/gluon/ tools.py, line 132, in __init__ payload = read_file(payload, 'rb') File /base/data/home/apps/s~app-id/1.357014326405166801/gluon/ fileutils.py, line 46, in read_file f = open(filename, mode) IOError: [Errno 13] Permission denied Is it possible to attach the stream in mail or even blobstore file?

[web2py] Attaching files stored in blobstore in a mail

[web2py] Join operations on google app engine
I have an online application deployed on google cloud. I have used web2py framework to develop the application. I have 2 tables the auth_user table and tasks table.Both of them have more than 1000 records each.The tasks table contains person_id field which stores the id's in auth_user table I need to fetch the data from 2 tables and display it. Since I am having large data it results in request time out(Deadline Exceeded Error). When I fetch from a single table it works fine. Since Google App Engine does not support JOIN operations I was fetching the entire data from both tables and then peforming operations, it would result to request time out. So I thought of adding the necessary fields that are in auth_user to tasks table but since there are more than 1000 records updating each record manually is cumbersome. Does web2py provide any bultin methods(like database validations) to update the fields based on person_id present or I should update it manually?
[web2py] Re: best way to fetch data from multiple tables?
Omi, We tried the solution that you have mentioned using join provided
by web2py, it works fine on local server.
But when we run it in google appengine sandbox or deploy it using
google app engine it gives the error Too many tables in the query.
Is there a solution to resolve this? Is there any other way of
implementing joins on google app engine which increases the
performance?

I'm not sure. I think it's more like join then filter.
Something like below...
query = (db.person.id==db.dog.owner) (db.person.name.like('Omi%'))
rows = db(query).select()

[web2py] Implementing task queue using web2py
I have an application on google app engine.
I have used web2py framework to develop the application
I have a module in which I need to fetch the records from 3 tables and
the final set of records contain data from all the 3 tables.
Here each of my tables contain more than 1000 records so when I
implemented it, it started throwing request time out error.
So I thought of implementing it using task queue.
While using task queue (push queue) . I have used the below code
def func():
from google.appengine.api import taskqueue
result=[]
if request.vars.download:
logging.info('Before task')
taskqueue.add(url=URL(r=request,c='abc',f='hello')) # abc is
the controller
logging.info('After Task')
return dict(result=result)
def hello():
logging.info('task queue implementation')
return
When I checked the log 'before task' and 'after task' info are present
but there is nothing logged in the log for hello function(where 'task
queue implementation' should have been present).
Please suggest if there is anything I need to add to this code to make
it work or If there is anything missing that I am unaware of.

[web2py] login with blank password:problem
Hi , i am developing an online booking system in web2py on GAE. The problem that i am facing is when i create an entity (client/ volunteer/employee) in my system , i store a random password in the db (auth_random_password()) and 'pending' in the registration key initially. but when i enable the login (registration_key = ) for an entity. i can login the system without typing anything in the password field. also if i do request_reset_password then the login functionality is working absolutely fine.(email as well as password is required after request_reset_password ) is it neccessary that when ever an entity (client/employee/volunteer) is created that we must do a request reset password in order for login functionality to work properly (with email and valid password) Is there any solution to avoid this ? Please suggest on this Thanks in advance.
[web2py] Pagination issue in GAE using web2py
Hi, I am developing an online booking application in python using web2py framework on google app engine. I have two tables, one is users table and other is activities table. My users table contains user id for each record and my activities table contains user id for whom an activity has been created. My user table has different authorization levels such as clients and volunteers. I have more than 1000 records in both activities table and user table. Now I need to fetch all the activities of all the clients. Since all the data cannot be displayed at a single click, I have used pagination. So I have used the limitby on my database queries. The issue that I am facing is When I try to match the id of people with the id present in activities, if first set of activities have been fetched using limitby and then I match them with the user id of clients and there is no match then the the records for the remaing id's are not fetched from the database. Please provide any suggestion on how to use limitby filter when we have data coming from more than one table(there is a one to one mapping in these two tables) Thanks in advance
[web2py] Deadline exceeded error/ Downloading data in csv via application
Hi, I am developing an online booking system. one of the functionality that i have implemented is to generate reports by gathering the data from two or more different tables. the problem that i am facing is due to large number of records (greater than thousand) , i was unable to render all the records into the view.(request time out) . to overcome this i implemented pagination which displays the records in small sets (using limitby filter on the database). by implementing the pagination i was able to remove the error while viewing the data. But in addition to viewing , i also have the functionality to download the same report in csv. due to the large data size i am unable to download the csv. it gives me deadline exceeded error. Please note my requirement is to download whole set of report in one csv.(more than 1000 records) I am thinking of implementing task queues for this ? Please suggest any solution for this.

is not happeningwhen i checked in appadmin that image is getting
stored into the DB but i am unable to retrieve it back(for

td{{=form.custom.widget.image}}/td
how i can retrieve image back so that it becomes visible in smaller

The recommended is:
Store the pictures on the file system and picture locations in the
database.
Why? Because...
1. You will be able to serve the pictures as static files.
2. No database access or application code will be required to fetch
the pictures.
3. The images could be served from a different server to improve
performance.
4. It will reduce database bottleneck.
5. The database ultimately stores its data on the file system.
6. Images can be easily cached when stored on the file system.
But if it is a requirement to store in database there is not to do about.

Yeah, that's probably better for names. Names can include hyphens as well.

Field('your_name', requires=IS_MATCH('\D+')
Note, \D will match any non-digit character, not just letters.
That is what I said: anything except 0-9.
It allows for surnames like 'Van der Merwe', O'Sullivan, 'Cronjé'
For finetuning - read the howto.
