[web2py] using generateDS web2py application wizard for making web applications from xsd files
Over the weekend I was working on and exploring the possibility of using generateDS.py http://www.rexx.com/~dkuhlman/generateDS.html to create python objects for an xsd file and modifyiing its included django script to instead create the web2py.metadata file that comes with the appadmin application wizard.

[web2py] Re: RuntimeError: Unable to handle upload
Hi Alan. Seeing your code must have helped because I did get it to run.
The following shows a demo script with functions to upload a file and
download a file utilizing a table containing a blob field. It worked twice
on a pdf for me. Note that I had to change the filename type from 'upload'
to 'string' in order to bypass an error message in the
dal._attempt_upload(fields).
# -*- coding: cp1252 -*-
import os, sys
from gluon import DAL, Field, fileutils
from easygui import fileopenbox, diropenbox

re-defining table?
db.define_table('wiki_media',
Field('filename', 'upload', uploadfield='filedata'),
Field('title', 'string'),
Field('filedata', 'blob'),

Hi Alan, Just now getting back to this days later...

[web2py] 'NoneType' object has no attribute 'split'
I think I figured this one out so I am posting the solution.
On the manages wiki_pages page from the manage pages memu item, I would
click on a media button and get the error below.
Turns out that in the course of testing my application I had uploaded files
without a title and web2py does not like media files without a title. Had
to go in to appadmin and delete the media files without a title and it
seems to be working now.
The confusing thing is that the error message was wanting to split the
title at '.' which you might expect for a filename but why a title?

[web2py] Re: Exposing validators as JSON?
Hi Alan,
Thank you for your work on the json data type. (Sorry for getting your name
wrong in my other post). These discussions are great for thinking through
my problem.
Yes I would need to post json data into the database and also search the
data, display and edit it also. My app is just one tool in a design
department storing design data for import/export to EDA sofware and test
lab benches. An 'attributes' table holds different design parameters of
designs and models.
For me, a 'json:reference attributes' field would basically be like a
list: string field but with only one string holding a json object of
a variable list of attributes with their value and unit. The actual
attributes table simply holds a list of available parameters (with default
values, types, usage and unit) users can select from to build their
parameter list. Kind of like a one to many relationship except there is no
reference to other tables and the list can vary. Perhaps the word reference
is not quite right then but I was reaching for some way
to succinctly describe it.
So the enhancement would:
use a select widget for the referenced table used in
creating/adding/removing Rows of values
have the ability to assign a grid object for viewing rows where the column
names match the fields in the referenced table
perhaps a widget should instead behave like the web2py app wizard where
another row of blank text fields can be added to edit your values
-- a drop down would have to be used in place of a select widget with
editable=referenced_table[field].writable and
visible=referenced_table[field].readable
match json data types to widgets where multiple always = True.
with json stored as a string then searching should be easy.
This is only my vision so someone else may have a different view of a
'json:reference my_other_table' usage.
-Bill

would a 'json:reference mytable' field type similar to 'list:reference

What would be the enhancement required specifically?
Do you need to PUT/POST json data into a DAL database with a service?
If you need to return the table structure, you can do something like:
table = dict()
for f in db.tablename:
if isinstance(f.requires, list):
requires = [type(r) for r in f.requires]
else:
requires = [type(f.requires),]
table[f.name] = {default: f.default, type: f.type, requires:requires
}
If you return the table object in the controller, the generic json handler
should serialize it automatically. Something similar could be implemented
for validation of forms

The json field type does not validate insert/update for values stored
programatically, validation is performed when you send values with the json

print IS_JSON()('{a: 1, b: 2}')[1] is None

[web2py] json validation
My app stores EDA information (cad programs for designing microchips) so

How do I expose validators as JSON?
I am not using web2py views in any capacity. Instead I am using
AngularJS.
So with web2py I am exposing my models RESTfully as JSON, and then
consuming them with AngularJS.
To reduce double-typing, how do I send field validators such as
`IS_EMAIL` as JSON?
# Model
db.define_table(
'foo',
Field('email', requires=IS_EMAIL())
)
# Controller
@service.json
def foo_form():
return dict(my_foo_form=crud.create(db.foo))
# Output I want
{ 'my_foo_form': { 'type': 'form', 'fields' { 'email',
'validator:IS_EMAIL'}, 'csrf': uid } }
With this I can then write the equivalent functions in JavaScript and
attach them to their corresponding fields.
How do I do this with web2py?
Thanks for all suggestions,

It looks like you're feeding jsonlint a string of the form myobj={some

[web2py] aµzing...
Been searching a while now for the magic decoder ring that solves the UTF-8 encoding issue. If I enter a mu (µ) by typing alt+0181 into my form field it looks fine. Then looking at the data in SQLDeveloper (Oracle) the data is 2 little boxes. NP I think the client encoding is wrong so I set my preferences to UTF-8 but µ is still 2 boxes. Still not worried yet but then I refresh or re-edit the field with the µ in it then it is returned from the database as two question marks. Same behavior occurs with the squared (²) sign...two boxes in db, two question marks in returned value on page. Anyone solve this yet? Thank you, Bill --

[web2py] Re: How many error tickets does a typical newbie handle?
No the app never really got to 100%. Even when I try to simplify it farther
and takes a different approach there is always a 'roadblock' of errors or
related errors. I get about 90% (I feel) finished and can't get to the last
10% without some round of errors that never gets 100% solved so I chalk it
up to poor programing and study harder simplify the design more. Spending
so much time on the book and in the code is helpful but if there was a way
to collect what the newbies are experiencing then some valuable index of
errors or more focused documentation can be created.
For exmample:
Today I'm trying to use ._after_insert_append(lambda f,id:... expecting f
to be a dict however the book actually has two lambda functions (for after
update after insert) with the same signature but get passed different
values.
So my frustration comes from not being able to find the correct way to
access the Set object on the _after_update. Why cant they both just get
dicts?
db.define_table('person',Field('name'))
def pprint(*args): print args
db.person._before_insert.append(lambda f: pprint(f))
db.person._after_insert.append(lambda f,id: pprint(f,id))
db.person._before_update.append(lambda s,f: pprint(s,f))

I noticed that you do not add auth.signature to your table definition. Does

If is_my_chart was somthing I needed often like I'd be tempted to change:
(full discloser: my track record is not good lately)
db.define_table('chart',
Field('chartName'),
Field('id_workbook',db.workbook),
Field('worksheet'),
Field('file','upload'),
auth.signature,
common_filter = lambda query: db.chart.created_by==auth.user_id,
format=%(id_workbook)s %(chartName)s,
)
Then when I needed a different controller function that returned all
records I could:
db(query, ignore_common_filters=True).select(...) # copied from
http://www.web2py.com/books/default/chapter/29/06?search=common_filter

[web2py] Re: auth.wiki() run Function
I don't think that functions in the controller are callable with a
parameter from the web page like form objects are but I could be wrong...
without double checking my code I believe you can call controllers like
this:
@{controller/function/args}
I found that on the markmin cheatsheet.
if you are not using markmin it might be
{{=MARKMIN(@{controller/function/args)}} however that is just a wild guess.
(Maybe I shiould just keep to myself if I don't know exxactly but perhaps
your pointed in a good direction.)

[web2py] Re: How many error tickets does a typical newbie handle?
Didn't have ANY problems with this line of work in 2 years of deployment. So your post does help with migration errors but... I have 81 tickets today mostly related to lambda taking [1|2] arguments but only [0|1] given. This leads to all sorts of variations leading to errors because sometimes '%(something)s' works and other times you just need r.something or simply lambda val: function(val). Much of my errors today were dealing with validators, looks like lambda functions and validators I had last week are not working now. Just when I figured my data tables were ready I have to go through each one line by line and rewrite validators lambda functions (and requires= and default= etc) I've already removed most of my referenced fields. Hope you guys plan on having a web2py boot camp very soon. There have been probably 74 or more posts made in this Google group in the last week so I can't think that I'm alone. I've read most of the code, all of the book and epidocs and most of the posts here and on stackoverflow. I bought the application developement cookbook, tried the slices. Kept my versions up to date etc... Still, I am probably going to get fired divorced for this project being so late after all the hours I put on it. -Bill --

[web2py] How many error tickets does a typical newbie handle?
The other day I read on web2py developers a discussion detailing Massimo's
vision of web3py. Perhaps us newbies can start collecting our tickets to
aide Massimo and the developers in understanding what is particularly
difficult or perhaps could use better documentation. Currently I have *480
tickets since 10/8* on my application before I decide to re-do it from
scratch for the 4th (hopefully last) time. Tickets would provide a wealth
of statistics about what us newbies are going through.
This time I decided to break my app up into 4 smaller applications. Start
over and my 2nd try this morning (after deleting and starting over) I
currently have 19 tickets in 45 minutes. When developing using SQLite I am
now getting the same errors that I had early on in my development
Adding columns is not trivial especial with all the combinations of:
migrate_enabled={True|False}, fake_migrate={True|False},
migrate='web2py_session_APPNAME', migrate.settings={True|False},
migrate={'table_name'|True|False|migrate.settings}. My approach was to use
the wizard to quickly whip out the app then add extra fields later so that
i can develop in small iterations. If just the tickets for what I am going
through this morning could be eliminated that would be huge!
FWIW,

[web2py] How to add a column?
Can't beleive this question does not come up in the search box. How do i add a column to a table using SQLlite? Simply adding hte field to the define table statement throws an error. Using SQLlite I cannot add a Field. I get an error message: OperationalError: no such column: source_via.substrate No Joke Really? When I set migrate_enabled=True then the message changes to something like the table sourc_via does not exist Of course it does since I just added the column that I'm being told does not exist either to it. On top of all that I am back to the Rocket server locking up. It likes to do that so I have to use Task manager to close it. Could be that session.connect +SQLlite is not a good combinnation. --
Re: [web2py] Re: Looking for a way to combine auto-complete with adding a non-existing item.
Now that is impressive. I did get it to work but not with SQLFORM or SQLFORM.smartgrid so that was a large part of my problem. When renderred in the view created by SQLGRID (clicking the ADD+ button) I would get the SQLFORM and the person fields were displayed with it's own submit button. This looked like it could be a bonus however the Add New link did not work (doesn't really need to if the form is already rendered) and information was not saved to the database. Confirmed this by visiting the grid again. I could see all of the users you added before. Looks like I'll drop use of SQLFORM in favor of this widget.Thank you for the sample app. It made a big difference. Regards, Bill --
Re: [web2py] Re: Looking for a way to combine auto-complete with adding a non-existing item.
This widget wouldn't break appadmin? would it? These are the many unknown
things that really frustrate me about web2py.
I edited the models file to test my current troubles adding columns to
tables that are already created. With your sample app, I was able to add
the new table and then add columns to cats. However when i edited the cat
to add a color or collar those new values were not saved.
db.define_table('collars',
Field('material', requires=IS_IN_SET(['leather', 'chain'])),
Field('size', requires=IS_IN_SET(['small', 'med',
'large'])),
format='%(size)s %(material)s')
db.define_table('cat',
Field('name','string'),
Field('color', 'string'),
Field('collar', 'reference collars'),
Field('person_id', 'reference person',

Re: [web2py] Re: Looking for a way to combine auto-complete with adding a non-existing item.
Hi Richard, In short...for myself and future searches...This widget works in a straight up crud form but with SQLFORM it has different behavior. Whether or not it is the source of appadmin not storing values is yet to be determined. After my columns were successfully added, values were set to null automatically of course. When I tried using appadmin to change the values (note this has nothing to do with the widget except the widget happens to be rendered on the edit or create page) the values do not update. Not saying it's the widget, I just don't know. Regards, Bill --

Something like that sounds like you just write a controller to query the

This view might work with the right controller:

{{for article in articles:}}
h1{{=article.title}}/h1
center
{{if article.image:}}

Now what in the heck to do with it?
The app wizard created a bunch of controllers like
@auth.requires_login()
def part_manage():
form = SQLFORM.smartgrid(db.part)
return locals()
but if I add
@{component:default/part_manage}
to my markmin I get a page with my SQLFORM.smartgrid inside a page so I
get two footers and two headers. Not to mention the add and edit pages
should really be a wiki page with my table attributes added.
Looks like auth-wiki is for creating web pages but what caught my
attention was the media and tagging capability built in so I don't have to
write my own app to do what's already there. However, I have a bunch of
tables (parts, sub parts, orders, samples, testing, analyses for tested
samples, etc...) defined for my application and basically 75% of the items
have attachments, images, files, user references and tags too.
Unless someone says different I guess I should be adding a wiki_page
column to all of my tables? Then create separate edit/show/create
controllers that generate the proper...slug...and return a wiki page?
That shouldn't break my relationships I don't think.
Just kind of wondering if there's already a know technique for my
application that you know of?

[web2py] Re: auth.wiki usage - Another Oracle DB Gotcha
About 6 days ago I posted my saga of failed attempts to get plugin_wiki to work with oracle and to add the blob field. You told me to put return auth.wiki() in my controller and use the built in auth wiki but I needed a bit more information and Oracle was still complaining. Alan told me to add auth.wiki(resolve=False) to my db.py file. Which eventually worked. But by that time the tables were created. Looks like it's working as expected, even storing and retrieving the data with a blob field. So far so good except when I click on the search link for the wiki (/default/index/_search) I did get this error that I haven't yet dug into very deeply but here it is: Traceback (most recent call last): File C:\web2py_src_2.1.1\web2py\gluon\restricted.py, line 209, inrestricted exec ccode in environment File C:/web2py_src_2.1.1/web2py/applications/TAMOTO/controllers/default.pyhttp://127.0.0.1:8000/admin/default/edit/TAMOTO/controllers/default.py , line 240, in module File C:\web2py_src_2.1.1\web2py\gluon\globals.py, line 187, in lambda self._caller = lambda f: f() File C:/web2py_src_2.1.1/web2py/applications/TAMOTO/controllers/default.pyhttp://127.0.0.1:8000/admin/default/edit/TAMOTO/controllers/default.py , line 20, in index return auth.wiki() File C:\web2py_src_2.1.1\web2py\gluon\tools.py, line 3227, in wiki return self._wiki.read(slug)['content'] if slug else self._wiki() File C:\web2py_src_2.1.1\web2py\gluon\tools.py, line 4705, in __call__ return self.search() File C:\web2py_src_2.1.1\web2py\gluon\tools.py, line 4990, in search content.append(self.cloud()['content']) File C:\web2py_src_2.1.1\web2py\gluon\tools.py, line 5001, in cloud orderby = ~count, limitby=(0,20)) File C:\web2py_src_2.1.1\web2py\gluon\dal.py, line 8790, in select return adapter.select(self.query,fields,attributes) File C:\web2py_src_2.1.1\web2py\gluon\dal.py, line 1615, in select return self._select_aux(sql,fields,attributes) File C:\web2py_src_2.1.1\web2py\gluon\dal.py, line 1580, in _select_aux self.execute(sql) File C:\web2py_src_2.1.1\web2py\gluon\dal.py, line 2856, in execute return self.log_execute(command, args) File C:\web2py_src_2.1.1\web2py\gluon\dal.py, line 1687, in log_execute ret = self.cursor.execute(*a, **b) DatabaseError: ORA-00904: WIKI_TAG.WIKI_PAGE: invalid identifier On Tuesday, October 16, 2012 12:20:30 PM UTC-5, Massimo Di Pierro wrote: On Tuesday, 16 October 2012 11:23:29 UTC-5, Bill Thayer wrote: Note for future searchers people as foolish as I am to try and use Oracle for web site backend.

[web2py] Auth Wiki functionality?
Hello everyone,
Thanks to Allen, Villas, of course Massimo among a few others I have web2py
auth.wiki with Oracle storing the media blobs and all the pages. I believe
I can use the wiki features in a structure way to improv productivity and
cross department functionality in my workplace.
Now what in the heck to do with it?
The app wizard created a bunch of controllers like
@auth.requires_login()
def part_manage():
form = SQLFORM.smartgrid(db.part)
return locals()
but if I add
@{component:default/part_manage}
to my markmin I get a page with my SQLFORM.smartgrid inside a page so I get
two footers and two headers. Not to mention the add and edit pages should
really be a wiki page with my table attributes added.
Looks like auth-wiki is for creating web pages but what caught my attention
was the media and tagging capability built in so I don't have to write my
own app to do what's already there. However, I have a bunch of tables
(parts, sub parts, orders, samples, testing, analyses for tested samples,
etc...) defined for my application and basically 75% of the items have
attachments, images, files, user references and tags too.
Unless someone says different I guess I should be adding a wiki_page column
to all of my tables? Then create separate edit/show/create controllers that
generate the proper...slug...and return a wiki page? That shouldn't break
my relationships I don't think.
Just kind of wondering if there's already a know technique for my
application that you know of?
Regards,
Bill

[web2py] Re: auth.wiki usage
Hi villas, Yes I agree and did do that. My development is at point where my tables are defined. If I go much farther into development without deploying to the test server than it is too difficult to narrow down errors so i want to focus on the basic functionality up front. With all of the errors I have I really need to nail down the migration in small steps at a time. To simplify my final design I'd really like to use the built in wiki. I'd also like to store my file objects in the database and not in the server. So my goal is to add a blob field to the auth.wiki(). So a small incremental approach is best for me while I fight through all of the challenges.

[web2py] Re: auth.wiki usage
Hi Massimo.
Yes the problem is not with the sqlite. I just confirmed that it does work
and the session table is in the databases folder.
My Oracle db already has the auth tables and web2py_session table defined.
I suspect there is a null value for the user field since no one would be
logged in when the app comes up. Somehow that is OK with SQL lite.
Here are the session variables:
Variables
session Storage {'auth': None, '_user_agent': {'os': {'...ser': {'version'
: '15.0.1', 'name': 'Firefox'}}}
request Storage {'function': 'index', 'body': cStringI...lications\\
TAMOTO\\', 'post_vars': Storage {}}
session._try_store_in_db bound method Session._try_store_in_db of
Stora...er': {'version': '15.0.1', 'name': 'Firefox'}}}
response Storage {'body': cStringIO.StringO object at 0...a at
0x03FE8F30, 'view': 'default/index.html'}
As I mentioned earlier. This is a brand new application. No tables other
than auth_ and web2py_session_ defined here yet.

Cool! The wiki_ tables are now visible in the app admin pages! My app does
not produce errors wrt wiki_.
However, the login page will not login any users, I can not register a new
user and cannot create or edit users from app admin although the auth_
tables are all visible. In fact I just tried to create a record for a
completely different table and it would not create it.
I think my db connection is OK since I did fix 2 web2py errors by creating
2 missing columns in SQL Developer and corrected ora errors 'Table does not
have attribute 'WIKI_PAGE'.'HTML' 'WIKI_MEDIA'.'IS_ACTIVE'. Those columns
were missing when I manually created the Oracle wiki_ tables.
Thank you for your help. My spirits are getting better now. Just need to

I wonder if you shouldn't call .define_tables() before calling
auth.wiki(), there could be need of configuring auth tables before creating
the wiki tables.

[web2py] Re: auth.wiki usage
the index displays the login page but after logging in returns the login page without logging in the user (user is in db) editing the user from auth_user edit user page returns the edit user page without committing the changes. registering a new user or adding one from auth_user simply returns the same page without creating the user. I thought I would try using the sqllite db like you did. The error said that auth user tables were not created so I cleared my session information, editited auth.define_tables(username=True, migrate=True) #set migrate=True and re-started the server...ooopsnot good.

I have created a scaffolding app with the default Sqlite connection that extends the wiki_page table with extra fields, list the wiki tables in appadmin and does auth_user crud without issues. What is the output if you submit an auth_user create form? Does web2py return any error traceback or anything? --

To force the wiki class to define the tables before serving the wiki pages
(so you can customize them) you must add something like this to the model
auth.wiki(resolve=False)
