[web2py] Re: Web2py: Create a CSV file to download for an executesql result
Here's an old post with the solution that I use for this https://groups.google.com/d/msg/web2py/4QhEULmJ8YE/aNBcJv81RocJ Yep, I've got a processing app that spits out all sorts of csv files based on data gathered from multiple sources. Here's a little helper function I use def csv_export(records, column_names, fields, mode = 'dal'): Export DAL result set, list of dicts or list of lists to CSV stream for returning to user Arguments: records = the data to be returned column_names (list)= the column names/headings for the first row in the CSV file Example ['First Name', 'Last Name', 'Email'] fields (list) = the names of the fields (as they appear in records) in the order they should be in the CSV. Example ['f_name', 'l_name', 'email'] or ['table_a.f_name', 'table_a.l_name', 'table_b.email'] If mode = 'list' and your records are in the correct order then fields may be None otherwise use [1,3,0] if you list is in a different order mode (string) = what type of data is in records? 'dal' (Default), 'dict' or 'list' 'dal' if records came from a regular dal query (Default) 'dict' if records are a list of dicts (for example using db.executesql() with as_dict = True) 'list' if records are a list of lists/tuples (for example using db.executesql() with as_dict = False) #create fake file object import cStringIO file = cStringIO.StringIO() #setup csv writer import csv csv_file = csv.writer(file) #write first row withspecified column headings/names csv_file.writerow(column_names) #which mode - dal or dict? if mode.lower() == 'dal' or mode.lower() == 'dict': for record in records: csv_file.writerow([record[field] for field in fields]) elif mode.lower() == 'list': if fields == None: csv_file.writerows(records) else: for record in records: csv_file.writerow([record[field] for field in fields]) return file Then in a controller you can have something like csv_stream = csv_export(processed_dataset, column_names, fields, mode = 'dict') response.headers['Content-Type']='application/vnd.ms-excel' response.headers['Content-Disposition']='attachment; filename=data_for_%s.csv' % date.today() return csv_stream.getvalue() which will cause browser to download the csv file with your chosen filename you could also turn around and save the datafile to the filesystem if you wanted. Hope this helps!

[web2py] Re: Belongs not working
Yes, but you are doing the opposite here. You are not checking whether a field value belongs to a list - you are checking whether a list stored in a field contains a particular value. The book section on the list:-type fields specifically says to use .contains for this purpose. This is not a job for .belongs.

[web2py] saving and dumping variables
Wondering how to save and dump variables from web2py to a static python ide. In other words, import cPickle b = cPickle.dumps(a) c = cPickle.loads(b) That seems to work only inside a web2py session. Once I close the web2py application and if I want to load up the saved variable using an external IDE. c=cPickle.loads(b) doesn't work.

If I were to work locally I would have used the following mysql command: 'SELECT * FROM SOME_TABLE INTO OUTFILE '/tmp/test1.csv' FIELDS TERMINATED BY ',' ENCLOSED BY '' LINES TERMINATED BY '\n'' In my application a user can select certain criteria, a query is built in the controller according to the criteria and is executed with the executesql() method which returns a dictionary like object. My question is: is there a way to make a download link in the view to download a csv file of results returned by the executesql() method? Thank you!

[web2py] Re: Table Migration on GAE
Hello Massimo,
Where can I find the version for tester?
Also I am using SQL with MySQL with GAE through Cloud SQL, so the
check_reserved keywords is necessary right?
Once I have the new version I will test it and report here.
Thanks

auth.define_tables(username=False, signature=False)
consider that migrate_enabled is true by default so no need to set it.
Also the check_reserved keywords is designed for SQL and not GAE. It does
not hurt but it is not necessary. I do not swear by lazy_table because they
have some caveats. Let's try without that.
Can you help us check if this work? If, not what behaviour do you see? Do
you get a traceback?

Could you explain a bit more the there are no migrations on GAE, is it
only for the actual version and the fixed version will solve it?
I realised that I am using the 2.10.0-beta version of web2py. The one
downloaded from the main download page.

Hi,
I am having difficulties with table migration on GAE.
I deployed perfectly in the Google App Engine and everything is working
fine.
I then needed to make some change in the auth_user adding some extra
field but when I deploy again the new version, the migration doesn't occur
and the new column is not created.
Here is the code used:
db = DAL('google:sql://[app-name]:[db-name]/[table-name]',
migrate_enabled=True, check_reserved=['all'], lazy_tables=True)
then below:
auth.settings.extra_fields['auth_user'] = [Field('username_fb',
length=128, default=, unique=True, writable=False, readable=False)]
auth.define_tables(username=False, signature=False, migrate=True)
Any idea why the migration doesn't occur?
Is there a way to force web2py to do migration somehow?
Thanks for the help!
Best,

[web2py] Cannot check boolean field
Hi,
I have the following model:
#Abstract category model, has references from multiple translations
db.define_table('pitch_category') #No fields except for ID
#The category translations
db.define_table('pitch_category_translation',
Field('pitch_category', db.pitch_category,

get_default_translation(r.id)), label=T('Category')),

label=T('Language')),
Field('val', 'string', label=T('The translation')),
Field('is_default', 'boolean', label=T('This is the default translation.
NOTE: there should be only one per category!'))
)
When i try to check if is_default is True, i get the following error:
class 'gluon.contrib.pg8000.ProgrammingError'(('ERROR', '42804',
'argument of IS TRUE must be type boolean, not type character'))
This is my SQL statement:
sql =
SELECT
p.ID,
tr.val,
def.val
FROM pitch_category p
LEFT OUTER JOIN pitch_category_translation tr
ON p.ID = tr.pitch_category AND tr.lang = '%s'
LEFT OUTER JOIN pitch_category_translation def
ON p.ID = def.pitch_category AND def.is_default IS TRUE;
% language
Everything works, except for the boolean check...

[web2py] How to approach presenting API data in web2py ?
Hello
Looking at writing a front end to an AWS orchestration tool in web2py, I
already have the functionality required coded in python defs, so just
looking at presenting things nicely.
One thing I'll have to do a lot of, is present grids and dropdowns of data
that have come from lists and dictionaries returned by boto module, for
example in my controller, I tested this:
@auth.requires_login()
def stacklist():
xadb = DAL('sqlite:memory:')
xadb.define_table('stacks', Field('stack_name', label='Stack Name'),
Field('stack_status', label='Status'))
xadb.stacks.truncate()
awskey=auth.user['AWSKey']
awssec=auth.user['AWSSecret']
e2conn = boto.ec2.connect_to_region('eu-west-1',
aws_access_key_id=awskey,
aws_secret_access_key=awssec)
cfconn = boto.cloudformation.connect_to_region('eu-west-1',
aws_access_key_id=awskey,
aws_secret_access_key=awssec)
regions = boto.ec2.regions(aws_access_key_id=awskey,
aws_secret_access_key=awssec) #
# get and populate cloudformer stacks
#
stackList = cfconn.list_stacks()
for stackSummary in stackList:
xadb.stacks.insert(stack_name=stackSummary.stack_name, stack_status=
stackSummary.stack_status)
form = SQLFORM.grid(xadb.stacks,orderby=[xadb.stacks.stack_status,])
return dict(form=form)
This works, but if I wanted to create a dropdown for regions instead of
hard coding eu-west-1, I'd be doing this sort of thing again with a
different temporary db. And then there's lists for RDS snapshots, ec2
images, ec2 snapshots etc. Lots of lists of AWS resources to be presented.
Am I going about this the best way ? What other options exist for me to
present lists and dropdowns of data returned from third party API calls?
Thanks

We use Python in many classes but the goal is not teach python. The goal is to teach programming (for, if, def, return).

But if someone needs to create a brand new framework using different language or create a hybrid, how that person can go about doing it? Whats will be required at to level and at the lower level? Needs a rocket (or apache) server for example to start. But how that is interfaced into the code...I believe, the stand alone version with input and output of each modules in gluon/scipt can help (without running web2py), in understanding how each modules talk to each other and what are the underlying relationship that ties the server side to the client side. That will be very interesting to me. Again, since I am a rookie, this may be already answered and everyone on this site may already know all these. But I think, it will help me to learn the framework better to know whats inside and out.

[web2py] Minor issue when trying to download plugins from admin application
Hi,
I'm facing a minor issue when trying to install ckeditor plugin , so I
report it :
When using Download plugins from repository button in the admin application
interface as I cannot access the url web2slices.com the exception is caught
and the following happen :
Version
web2py™ Version 2.9.12-stable+timestamp.2015.01.17.06.11.03
Python Python 2.7.8: C:\Python27\python.exe (prefix: C:\Python27)
Traceback (most recent call last):

line 1919, in plugins
return dict(plugins=session.plugins[results], app=request.args(0))
TypeError: list indices must be integers, not str
type 'exceptions.TypeError'(list indices must be integers, not str)
This is the original code :
def plugins():
app = request.args(0)
from serializers import loads_json
if not session.plugins:
try:
rawlist = urllib.urlopen(http://www.web2pyslices.com/; +
public/api.json/action/list/content/Package?package +
_type=pluginsearch_index=false).read
()
session.plugins = loads_json(rawlist)
except:
response.flash = T('Unable to download the list of plugins')
session.plugins = []
return dict(plugins=session.plugins[results], app=request.args(0))
So I propose to replace line 1918 :
session.plugins = []
by :
session.plugins = {results : None}
Thanks for web2py !

[web2py] Re: saving and dumping variables
Actually,
I figured it out. All I needed to do is CD to the directory where web2py

from gluon import *
Thats it. Then if I do
c = cPickle.load(open('C:\Users\Ron\Desktop\web2py_src\myfile.pickle',
'rb'))
DAL object shows up as stand alone. Now I can do anything with it.

[web2py] Re: Write dynamic query in DAL without extra nested parentheses
In this particular case, you should instead use .belongs(): query = db.product.id.belongs([list of ids]) It's an interesting problem, though. A somewhat hackish solution would be: query = ' OR '.join(str(db.product.id == i) for i in [list of ids]) The problem is that OR and AND operators always wrap the operands in parentheses, even when not necessary. The result is the nesting you observe when using reduce() or appending in a loop. Perhaps there should be a way to suppress the parentheses when not needed.

The two header examples below allow framing if the ancestor page is from the same domain as the framed page. I wouldn't necessarily set the X-Frame-Options header by default in the framework, as that header is non-standard and being deprecated in favor of Content-Security-Policy, which itself is more flexible and allows specification of a whitelist of allowed ancestors. I was suggesting maybe setting Content-Security-Policy, with framing from the same domain allowed by default, and with an easy to set setting to specify a whitelist (e.g., response.allowed_frame_ancestors). I'm not sold on the idea -- just something to consider.

Note, you can also configure your server (e.g., nginx, Apache) to automatically set the above headers. You can also implement a Javascript defense, such as this one https://www.owasp.org/index.php/Clickjacking_Defense_Cheat_Sheet#Best-for-now_Legacy_Browser_Frame_Breaking_Script . 2.

It doesn't by default (as that is a user preference configurable in the browser), but nothing stops you from using the various available solutions, such as setting the autocomplete attribute of form and input elements to off (which can be done on the server or via Javascript) or using Javascript to reset the form after rendering.

In many of the adapters, web2py converts booleans to and from strings with

[web2py] Re: Web2py security questions
I did; it says nothing about the specific things I asked about (or if it does, I cannot tell); that is why I asked. If that section of the book *does* address my questions, could someone point me to where in that section it does so? For example, there is a reference to preventing CSRF, but not about anti-framing. - Scott P.S. Thanks for not LOL-ing me and saying this is an inappropriate forum for such a question, like my first reply (which has been deleted) -- progress!
