Re: [web2py] How to read image in blob format from a existing db
I could do it with pydal but with sqlite3 library worked perfect. Is maybe a
pydal bug ?
Cheers.

Re: [web2py] How to read image in blob format from a existing db
Data is already in binary in db.
Making more test when pydal retrieve the blob data from the db is only getting
just a part of the information.
When in print the rows after the select i get a small sample like this:
images = cherry_db(cherry_db.image.node_id ==
i['node_id']).select(cherry_db.image.node_id, cherry_db.image.png)
for m in images:
print(m['png’])
b'<\xd1\x88\x1c4l\x04\x84\xce 0\x13\xc6\x01\r\xdd\xd0'

[web2py] How to read image in blob format from a existing db
Hi, i’m trying to read images from a existing sqlite db. For some reason when i
save the images to disk, they are corrupted.
this is my code:
cherry_db = DAL('sqlite://{}'.format(form.vars.cherry_file),
folder=upload_folder, migrate=False)
cherry_db.define_table('image',
Field('node_id', 'integer', requires=IS_NOT_EMPTY()),
Field('png', 'blob')
)
images = cherry_db(cherry_db.image.node_id ==
i['node_id']).select(cherry_db.image.node_id, cherry_db.image.png)
for m in images:
name = str(uuid.uuid4())
print('image {}'.format(name))
print(m['png'])
im = open('{}'.format(session.project_folder+'/'+name+'.png'), 'wb')
im.write(m['png'])
im.close()
Any help is appreciated
Cheers.
Chris.

Re: [web2py] string validation
Hi, i don’t know a specific way to do that but maybe the following can help.
You can create a function which delete/disable the account with if some url
patterns are found in first name and last name
In your models add this function:
def _valid_user(s, i):
# i —> contains the user id
# s —> contains a dictionary with the user information
if any(c in s.first_name for c in ['www', 'http', 'https', '%', '/', '.']):
print('spammer user')
print('dissabling account’)
elif any(c in s.last_name for c in ['www', 'http', 'https', '%', '/', '.']):
print('spammer user')
print('dissabling account')
And this after auth declaration:
db.auth_user._after_insert.append(_valid_user)
Or maybe declaring manually the auth table with a custom validator, but I'm not
sure if is possible…
Cheers.
Chris.

Re: [web2py] Re: How to reject request based on location
Hi, here you have some examples:
Web server level
Here there is examples about how to deny an IP and network ranges in nginx, if
you can modify the nginx.conf file then is easy.
https://www.cyberciti.biz/faq/linux-unix-nginx-access-control-howto/
At OS level.
If you have control of IP tables you can do it there also.
This is how to block an entire subnet:
# iptables -A INPUT -s 192.168.100.0/24 -j DROP
Application level:
In your model (db.py) add the following at the beginning:
Example with multiples ip ranges
if IS_IPV4(minip=('192.168.20.19', '192.168.30.100'),maxip=('192.168.20.19',
'192.168.30.199'))(request['env']['REMOTE_ADDR'])[1] == None:
raise HTTP(403)

[web2py] Multiples requieres in SQLFORM
Hello list,
I need to have 2 requires in the same field, one requires must be a select
multiple, but also it can be a different value of initial select multiple,
this because in the view the select multiple values are changed with
javascript .
It is possible to make something like the following?:
Field("Grado", default=grados_roca[2],* requires=IS_NOT_EMPTY()
OR IS_IN_SET(range(2, (len(grados_roca) + 1)), grados_roca)), ??*
And if is possible, how could I make this ?
I tryied with this but i had no lucky:
Field("Grado", default=grados_roca[2], requires=[IS_NOT_EMPTY(),
IS_IN_SET(range(2, (len(grados_roca) + 1)), grados_roca))]),
this is my sql form:
SQLFORM.factory(Field("nombre_ruta", requires=IS_NOT_EMPTY()),
Field("Modalidad",
default=modalidades[1],requires=IS_IN_SET(modalidades)),
Field("Tipo",
default='Monolargo', requires=IS_IN_SET(tipo)),
Field("Grado",
default=grados_roca[2], requires=IS_IN_SET(range(2, (len(grados_roca) +
1)), grados_roca)),
Field("Largos", default="3",
requires=IS_IN_SET(range(1, 51))),
Field("Zona",
default=zonas_list[0],
requires=IS_IN_SET(zonas_list, zonas_list_name)),
Field("Observacion", 'text',
length=300,
default='No se han
registrado observaciones', label="Observaciones"),
_name="agregar_ruta",
submit_button="Agregar",
)
Cheers!
Chris.

Re: [web2py] Re: Exporting a table to csv
Hi Dave,
You’re right, I’m using python3. I thought it might be related to that so
yesterday I added an issue on the github site for the book:
https://github.com/web2py/web2py-book/issues/393
If that’s the wrong place/way please let me know.
Regards,
Chris

[web2py] Violating Unique constraint in field doesn't go to standard 500 page
Hello! I'm running 2.14.6-stable+timestamp.2016.05.10.00.21.47 and have hit this issue: If I have a Field where unique=True, inserting a row with a duplicate Field value triggers the constraint, as expected. However, the error does not lead to a page linking to a ticket, but instead to a generic page saying Server Error. I've traced the error down to this section of globals.py: @property def body(self): if self._body is None: try: self._body = copystream_progress(self) except IOError: raise HTTP(400, "Bad Request - HTTP body is incomplete") return self._body The error thrown by copystream_progress is of type , and seems to occur because of a timeout opening env['wsgi.input'] (globals.py, copystream_progress) I haven't been able to trace the error further, but here's the Rocket output to stderr: ERROR:Rocket.Errors.Thread-6:Traceback (most recent call last): File "\dynamic\gluon\rocket.py", line 1337, in run self.run_app(conn) File "\dynamic\gluon\rocket.py", line 1838, in run_app output = self.app(environ, self.start_response) File "\dynamic\gluon\main.py", line 653, in app_with_logging ret[0] = wsgiapp(environ, responder2) File "\dynamic\gluon\main.py", line 564, in wsgibase return wsgibase(new_environ, responder) File "\dynamic\gluon\main.py", line 534, in wsgibase if request.body: File "\dynamic\gluon\globals.py", line 281, in body raise HTTP(400, "Bad Request - HTTP body is incomplete") HTTP: 400 BAD REQUEST Any help you can give would be most welcome! -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

Re: [web2py] Re: Using validate_and_insert with a computed field
Many thanks Anthony!
That looks like it will work for now...I may specifically handle call that
code just before validate_and_insert calls in the web app, so I don't get
rid of readURL validation in a place where I need it.

Re: [web2py] Re: Using validate_and_insert with a computed field
Can do, here's an example:
# DB
db.define_table('story',
Field('title',
length=512,
widget=lambda field, value: SQLFORM.widgets.string.widget(field,
value,
_size=40),
requires=[IS_NOT_EMPTY(), IS_LENGTH(minsize=1, maxsize=512)]),
Field('titleAsSlug',
compute=lambda(r): urls.convert_to_slug(r['title'])),
Field('readURL', unique=True, label=T('URL'), required=False,
widget=lambda field, value:
SQLFORM.widgets.string.widget(field,
value,
_size=60,
_placeholder=
'http://www.example.com')),
)
# Test
class TestModels(unittest.TestCase):
def testStoryNewCreate(self):
dct_new_story = {
"title": "Unit Test"}
new_story = db.story.validate_and_insert(**dct_new_story)
self.assertFalse(new_story["errors"], "Error inserting a new story:
" + str(new_story))
The readURL field generates an error that the entry is found in the
database. Unique=True is a DB constraint according to the web2py manual and
NULLs in PostgreSQL and SQL in general don't violate the unique constraint.
Web2py attaches an IS_NOT_IN_DB validator that converts None to "None"
instead of null, which only works until there is a row entitled 'None'.
The titleAsSlug field is set to an empty string by the validator, which is
perhaps why validate_and_insert doesn't compute it where insert does.

Re: [web2py] Re: Using validate_and_insert with a computed field
Thanks for the update!
I'm passing all of the fields needed by the compute function. It looks
something like this:
dct_new_user = { fields here }
# new_user = db.auth_user.insert(**dct_new_user)
new_user = db.auth_user.validate_and_insert(**dct_new_user)
The former calculates the computed field, but the latter does not.

Uh oh...I just removed requires from the computed field and reran my unit tests, and now validate_and_insert inserts but the computed field isn't calculated at all!

[web2py] Using validate_and_insert with a computed field
Hello,
I've got a users table with a computed field:
db.define_table(
auth.settings.table_user_name,
[...]
Field('calculated_field', requires=IS_NOT_EMPTY(),
compute=lambda(r): calculate_field(r)),
And a bit of code that uses validate_and_insert() to insert a row:
dct_new_user = {...}
new_user = db.auth_user.validate_and_insert(**dct_new_user)
This code always fails, returning
Is this a bug? If not, what should I do to get around it?
Thanks!

[web2py] MySQL / Web2py datetime issue
I have a manually built the MySQL table and then use migrate=False in
Web2py. I can enter hours use the add_to_table function passing in the
table_name, the work_date_start and work_date_end show up in this form as
the datetime picker. I can choose from this and add the info into the
table, as they show up correctly in MySQL. When I try to view the data in
show_table function these two dates show up as None. The timestamp field
time_added_to_table does show the datetime correctly in a format like
'2017-02-10 19:37:35'. Any ideas?
Below are the descriptions of MySQL and the Web2py info used.
I manually build tables in MySQL, here's the table using describe
billable_hours;

auto_increment |
| time_added_to_table | timestamp | NO | | CURRENT_TIMESTAMP
||
| work_date_start | datetime(6) | YES | | NULL
||
| work_date_end | datetime(6) | YES | | NULL
||
| work_details| text| YES | | NULL

||
| billing_state_id| bigint(20) | YES | MUL | NULL

[web2py] Re: Not seeing logging.error messages in nginx error_log
Hi DaveS, So to clarify when I used mod_wsgi & apache I used to get logging.error messages saved into my apache error.log . Now that I use uwsgi & nginx this doesn't happen. I am not sure what your answer means as I am not familiar with what a logging.conf file is. I cannot find a logging.conf file in either /etc/uwsgi /etc/nginx or under my web2py instance. I am not particularly trying to consolidate logs - I am not seeing these messages in any log.

[web2py] Not seeing logging.error messages in nginx error_log
Not seeing logging.error in nginx error_log I have a mostly successful install of web2py application with uwsgi and nginx on centos using setup-web2py-nginx-uwsgi-centos70.sh . But I can't figure out how to configure nginx, uwsgi and wsgihandler.py so that logging.error messages appear in the error_log file. I have been able to configure it so that nginx [notice] and [info] messages appear but these are generated by nginx itself and are not coming from logging.notice or logging.info calls in the web2py application. Can someone post a recipe as to how this is done?

[web2py] How to start a web2py application on another ser
Hi guys, I currently have two systems that have web2py installed on them. System 1 has app1 installed on web2py and System 2 has app2 installed. Is it possible for me to call functions of app2 which is on System 2 using app1 which is on System1? They are both connected to my home network.

[web2py] How to include session data in error tickets
Hello,
I put this function in my controller to test error handling:
def error():
raise Exception("I am a test error.")
When I go to /error, I get an error ticket, as expected, but that error
doesn't include any data, just the traceback. I seem to recall a few years
back that tickets would include helpful things like the current session
state, variables being passed to each function, etc. but now I almost never
see that information.
Did something change in web2py? I feel like this should be obvious but I'm
at a loss for where to look.
Thanks!

[web2py] Re: Caching Logic in web2py
Awesome! Thank you very much for this explanation! All the best, Chris On Tuesday, April 28, 2015 at 6:22:49 PM UTC-4, Leonel Câmara wrote: This one: A. Does the cached object get updated: The cached object is updated immediately because it's the same object. Cache ram does not clone it. Notice that the behaviour will be different if you're using cache disk. Do know that doing this is a very bad idea, as you will run into all sorts of thread safety problems. You should consider cached values immutable if you don't want to worry about safety yourself. And finally, if I wish to force a changed value of some_object to be saved to the cache, am I correct that I should then call: some_object.arg3 = some_object = cache.ram(self.id_attribute, lambda self, time=0) This will force the change, but, again, if it's the same object the change will already be there. Does this mean that the next time someone instantiates an object of class SomeClass with the same arg1 value but a different time_expire value, the cached object will be overwritten? It will be overwritten if the cached value has a timestamp that is expired with the given time_expire value. I think that maybe your problem is that you're not understanding what the cache is actually saving in your example. When you put an object in cache ram, what's actually in the cache is a reference to the object. So if you have a reference to that same object somewhere else and you modify it, you're actually modifying the same object that cache is referencing. Cache disk is different, because cache disk pickles your object and when you ask it for a value it unpickles it, so each time you will get a new object albeit with the same attributes. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Caching Logic in web2py
Hi Everyone, I have some questions about how caching works in web2py. I'm not interested at this point in understanding how to cache entire views or anything like that - in this case, I'm interested in understanding the principles behind how web2py implements caching: Let's say that I have a class that accepts some arguments that is defined like so: class SomeClass(): def __init__(self, arg1 = None, arg2 = None, arg3 = None): self.arg1 = arg1 self.arg2 = arg2 self.arg3 = arg3 if arg1 is not None: self.id_attribute = 'ID Value Here' + arg1 self = cache.ram(self.id_attribute, lambda self, time=(60*60*24* 30)) return self Now the *first* time I instantiate an object of SomeClass, say by calling: some_object = SomeClass(arg1=123, arg2=456, arg3=789) Then this will create an object of class SomeClass, and (because arg1 is not None) will save that object to the cache (in ram) with the following attributes: some_object.arg1 == 123 some_object.arg2 == 456 some_object.arg3 == 789 some_object.id_attribute == 'ID Value Here123' Is the above so far correct? If so, then what happens if I perform an operation on some_object, like so: some_object.arg2 = 654 In this case: A. Does the cached object get updated: - if this statement gets executed (60*60*24*30) seconds from when the object was instantiated? - if this statement gets executed (60*60*24*30) seconds from when the object was instantiated? or: B. The local object gets updated, but the cached value does not change: - if this statement gets executed (60*60*24*30) seconds from when the object was instantiated? - if this statement gets executed (60*60*24*30) seconds from when the object was instantiated? or: C. Something else? And then what happens when I have some other function try to do something using some_object? some_other_value = some_object.arg2 + 987 Specifically, does the value of some_object.arg2 get read from the cache or from the object itself: - if this statement gets executed (60*60*24*30) seconds from when the object was instantiated? - if this statement gets executed (60*60*24*30) seconds from when the object was instantiated? And finally, if I wish to force a changed value of some_object to be saved to the cache, am I correct that I should then call: some_object.arg3 = some_object = cache.ram(self.id_attribute, lambda self, time=0) which will explicitly change the cached version of some_object? Does this mean that the next time someone instantiates an object of class SomeClass with the same arg1 value but a different time_expire value, the cached object will be overwritten? Any help / clarification / explanation would be much appreciated!

[web2py] Why does the auth.login() form use a custom URL function with self.settings.controller?
Hello! I was recently debugging an issue with my login forms - on a failed
login, I redirect to a nonexistent page.
Let's say I'm on /init/controller1/method1 and insert an auth.login() form.
On a failed login, we redirect to the request page:
redirect(
self.url(args=request.args, vars=request.get_vars),
client_side=settings.client_side)
https://github.com/web2py/web2py/blob/master/gluon/tools.py#L2512
I had assumed this method would bounce you back to the page you made the
failed login attempt on. However, instead of using the current controller,
it uses auth.settings.controller:
def url(self, f=None, args=None, vars=None, scheme=False):
if args is None:
args = []
if vars is None:
vars = {}
return URL(c=self.settings.controller,
f=f, args=args, vars=vars, scheme=scheme)
https://github.com/web2py/web2py/blob/master/gluon/tools.py#L1250
Is there any particular reason that we jump to a specific controller, no
matter what controller auth.login is on? I changed auth.settings.controller
to None and it seems to work great, but I was wondering if we could remove
this setting.
Thanks!

Re: [web2py] Re: reddit clone - foreign key constraint failed
Hi William,
Thanks for the information!
Regards,
2014-12-23 8:33 GMT+00:00 William Chen williamch...@gmail.com:
Hi Chris, I had the same problem and found this thread when I was
searching for a solution.
The solution is to simply create 1 or more comments using app admin.
If table B references table A, then you need populate to populate table A
before you populate table B, else there will be an error. In our case, the
table comm references to itself in this line:
Field('parent_comm', 'reference comm')
So we need to manually add new comments, before we populate the table
comm.
Hope this helps.

Re: [web2py] How to pass an array from jQuery to controller
Eval can be used to crash a Python app or hack into it, so *please don't
use it*, as tempting as it may be!!
(http://nedbatchelder.com/blog/201206/eval_really_is_dangerous.html)
I spent some time working on this and found that something like this is a
decent way to do it:
script
//http://stackoverflow.com/questions/8890524/pass-array-to-ajax-request-in-ajax
info = [];
info[0] = 'hi';
info[1] = 'hello';
$.ajax({
type: POST,
data: {info:info},
url: index.php,
success: function(msg){
$('.answer').html(msg);
}
});
/script
In web2py:
def getRequestVars(name):
varValue = request.vars[name + '[]']
if type(varValue) == str:
return [varValue] #check for single value
else:
return varValue
info = getRequestVars('info')
This approach is nice because you can use both web2py and jQuery's
automatic array handling. :)

the above will call this url:
/default/mycontroller?array=['Sun','Mon','Tue','Wed','Thu','Fri','Sat']
def mycontroller():
# Here, I wanted to receive xyz as an array.
myarray = eval(request.vars.array)
the above will receive the string and evaluate as a Python list.
(BUT, BE CAREFUL!! it can be used to crash your app)
another solution may be better than the above, is to split the array as
args and pass it separated.
script
var xyz= ['Sun','Mon','Tue','Wed','Thu','Fri','Sat'];
args = xyz.join(/)
$(function() {
$(body).click(function(event) {
ajax({{=URL('default','mycontroller')}}+args ,[],'target');
});
});
/script
the url will be called as
/default/mycontroller/Sun/Mon/Tue/Wed/Thu/'Fri/Sat
in controller
def mycrontroller():
array = request.args
array[0] # Sun
The second approach is better ans safe.

[web2py] Is it easy to create a grid data entry form using web2py?
This may be trying to run before I can walk but never mind! :-) Is it easy to create a grid type table editing form in web2py? I just want an easy way to edit an existing table, edit existing fields and add new rows. It's just simple data, text and numeric fields in a sqlite3 database. I want to edit the data in place, no pop-up forms or windows, just click on a field and edit the data, tab to the next field and the changed data is saved (could be delayed to when on leaves the form but I don't want to have to do any explcit 'save' action). Add a new row at the bottom by tab off the last field of the last existing row or maybe cursor down on last row or just have an empty row always at the bottom (like MS Access). The table will already exist and I want to see all the columns, no need for views or selects (though I might find uses for them in the future). This is to run on an existing system (xubuntu 14.04) running apache2 web server with various bits and pieces already running on it. I'm fairly happy with installing web apps and use Python quite a lot for small scripts but I haven't really worked with a development framework like web2py before. -- Chris Green -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

To add parameters to a formstyle function, you first create your own version of the basic formstyle (as you did with your version of the bootstrap3 form), then wrap it in a lambda which presets the new values you added to the signature.

[web2py] Problem with uploads using a remote sftp file system
I am trying to deploy my web2py app on Heroku. I have a database table
containing an upload field that I want to put on a remote filesystem using
sftp. In db.py, I have set up the file system:
from fs import sftpfs
file_system = sftpfs.SFTPFS('???',
root_path='???',
username='???',
password='???')
In my table I define a field:
Field('zip_file',
'upload',
required=True,
uploadfs=file_system,
autodelete=True)
If I run my app on my local machine, the file is uploaded to the sftp
server as expected. When I run the app on Heroku (which will use a
postgresql database) it does not go to the remote filesystem, rather is
placed into the postgresql database on Heroku. Any ideas why this wouldn't
be working?

[web2py] Re: Problem with uploads using a remote sftp file system
After some digging, I think I may have found the issue. See my pull
request: https://github.com/web2py/web2py/pull/409. Comments welcome.

I am trying to deploy my web2py app on Heroku. I have a database table
containing an upload field that I want to put on a remote filesystem using
sftp. In db.py, I have set up the file system:
from fs import sftpfs
file_system = sftpfs.SFTPFS('???',
root_path='???',
username='???',
password='???')
In my table I define a field:
Field('zip_file',
'upload',
required=True,
uploadfs=file_system,
autodelete=True)
If I run my app on my local machine, the file is uploaded to the sftp
server as expected. When I run the app on Heroku (which will use a
postgresql database) it does not go to the remote filesystem, rather is
placed into the postgresql database on Heroku. Any ideas why this wouldn't
be working?

Hi Massimo, I don't think the binary is working on my system; I am using OSX Mavericks (10.9.2).

[web2py] subscripts inside database
In my current project I have a table that accepts chemical formulas. To accurately display a formula, however, I need to be able to render subscripts. I had tried to put an HTML sub tag around the number, but this is saved as lt;subgt; Normally I would love that web2py does this automatically for me, but in this instance it was the only way I could think to make this work. Is there a way to insert a subscript number into a database and have it render properly automatically? -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] Re: Problem with web2py on Heroku
I think I may have made sense of the error above. Based on the code below,
DatabaseStoredFile.web2py_filesystem is set to true even if the table
creation fails (which it does), as I don't think the error will be caught
before it gets to that line. A few lines later, it tries to access that
table, causing the error logged by Heroku. Therefore, the key error seems
to be that the creation of the web2py_filesystem table is failing.
if not self.web2py_filesystem:
if db._adapter.dbengine == 'mysql':
sql = CREATE TABLE IF NOT EXISTS web2py_filesystem (path
VARCHAR(255), content LONGTEXT, PRIMARY KEY(path) ) ENGINE=InnoDB;
elif db._adapter.dbengine in ('postgres', 'sqlite'):
sql = CREATE TABLE IF NOT EXISTS web2py_filesystem (path
VARCHAR(255), content TEXT, PRIMARY KEY(path));
self.db.executesql(sql)
DatabaseStoredFile.web2py_filesystem = True

Somehow there is a problem with the web2py_filesystem table where web2py
stores metadata on platforms that lack a persistent filesystem. This an be
recovered but it is complicated to explain without direct access to the

[web2py] Re: Problem with web2py on Heroku
Hi Massimo,
This application worked until I switched to the Postgresql database, so it
is definitely a database problem. Originally I was using the default
database, which I guess is file-based, so the data would be lost about once
a day when Heroku cleaned out its files. That was fine for testing, but
obviously I need a persistent database for production.
Right now, I don't care about the data in the database; in fact it should
be empty since it has not worked since I changed the database.
I have already tried deleting the database by removing the add-on from
Heroku and adding a new one. According to the Heroku admin panel there are
no tables existing in the new database.
I also tried deleting the app from Heroku and deploying it all over again,
which also did not work.
Can you elaborate or point to some information on how web2py treats the
metadata? There is no web2py_filesystem in my database. Can you think of
a reason why it would not have been created?
Chris

9e6a7c1bb77d791a89631de258057aed_web2py_session_CaeSuite.table
Why is it looking for a file in */databases?

Is this is a problem that worked before and then stopped working? Have you
changed anything on the database side? Do you have data that you need to
recovered.
If at all an option, try delete the database and make a new one.
Somehow there is a problem with the web2py_filesystem table where web2py
stores metadata on platforms that lack a persistent filesystem. This an be
recovered but it is complicated to explain without direct access to the
system. It really depends on how it got there and what is in there.

[web2py] Displaying computed data from form submission
I have played with doing this several different ways, but to no avail.
Currently I have a function:
def qrret():
rows = db().select(db.geo_item.f_name,db.geo_item.f_qrcode, orderby=db.
geo_item.f_name)
rows2 = db().select(db.geo_collection.f_name, db.geo_collection.f_qrcode
, orderby=db.geo_collection.f_name)
items=[]
colls=[]
for row in rows:
items += [
OPTION(row.f_name, _value=row.f_qrcode)
]
for row in rows2:
colls += [
OPTION(row.f_name, _value=row.f_qrcode)
]
fields = [DIV(H4(Items), SELECT(items, _name=items, _multiple=True,_size
=10), _class=span6),
DIV(H4(Collections), SELECT(colls, _name=colls, _multiple=True,_size
=10), _class=span6), BR(),
DIV(INPUT(_type='submit'), _style=margin-top: 20px, _class=
span12)]
form=FORM(fields, onvalidation=qrparse)
return dict(form=form)
This function returns the form as I need it in the view. The onvalidation
function 'qrparse' is:
def qrparse(form):
codes = form.vars.items
codes += form.vars.colls
images = qrmake(codes)
return images
Which in turn calls:
def qrmake(codes):
images = []
background = Image.new('RGBA', (1275,1650), (255, 255, 255, 255))
margin = 150
bg_w,bg_h=background.size
offset_left = margin
offset_down = margin
rowend = bg_w - margin
pageend = bg_h - margin
for i in xrange(len(codes)):
code = codes[i]
try:
img = Image.open(request.folder + 'uploads/' + code)
except:
continue
img.thumbnail((300, 300), Image.ANTIALIAS)
img_w,img_h=img.size
pasted = False
while pasted == False:
if offset_left + img_w rowend:
offset_down += img_h
offset_left = margin
elif offset_down + img_h pageend:
images += background
images += qrmake(codes[i:])
return images
else:
background.paste(img,(offset_left,offset_down))
pasted = True
images += background
return images
What I need to happen though is to display the images that I generated in
the validation. I have played with doing this several different ways, but
nothing has worked so far. Am I approaching this the wrong way or is there
something I am missing?

[web2py] Re: Displaying computed data from form submission
I feel ridiculous admitting this, but I didn't realize I had omitted the
code saving them into the global variables. The result set doesn't need to
be persistent, so storing it to the database would be unnecessary. It will
only be displayed to the user once.

Did you guessed qrparse return values are being stored in form or
somewhere?
You need to store in a cookie, global variable (and then show them in the
view using {{=}}) or maybe save in in the form like a prepopulate field (I
don't know where you want to show the images).
Could you tell us where would you like to show the images?

Re: [web2py] Re: Dynamic form generation using FORM()
I actually have a very odd data set that is getting put into the form. They represent several different tables and the only real unifying feature is the uploaded photos. The idea is to fetch a list of photos to retrieve for the user using a single form. That is why the checkbox value is the encrypted name of the file and the assigned name is displayed next to them.

[web2py] Dynamic form generation using FORM()
I am trying to make a custom form which allows the selection of a set of images that are in the database. So far I have the following code: rows = db().select(db.a_table.name,db.a_table.image) fields = [] for row in rows: fields += [ INPUT(_type=checkbox, _value=row.image) , row.f_name ] form=FORM(fields,INPUT(_type='submit')) I know for sure that the database query is correct and is not a problem at all now.

[web2py] Re: Dynamic form generation using FORM()
You know, I hate to say it but that never even occurred to me to try. I got so distracted with other things that I never took the time to really evaluate what could be happeing. Thank you, Anthony. On Tuesday, January 14, 2014 5:23:23 PM UTC-7, Anthony wrote: If you want to submit a list of inputs to FORM(), then that's all you can submit. So, append the submit input to the fields list and then just do FORM(fields). Also, if db.a_table.image is an upload field, it will just store the transformed filename, which won't be very informative to the users. You'll probably want to show the original filename (it may be easiest to store that in a separate field rather than extract it from the transformed filename).

You have to manually alter table and remove the UNIQUE attribute. web2py
is not smart enough to be able to do that.

div class=post
On {{=post.created_on}} {{=post.created_by.first_name}}
says span class=post_body{{=post.f_comment}}/span
/div
{{pass}}
{{=form}}
The table definition I used had f_comment in place of body for the main
text of the comment.
comments.py:
@auth.requires_login()
def post():
db.t_comment.f_approved.writable = False
db.t_comment.f_approved.readable = False

the functionality is there. But when the index page loads, it never gets
beyond loading

[web2py] Web2Py Hangs on Recaptcha Form Submission
Hello all,
I'm having an issue where I am using a simple form controller that
essentially just has a Recaptcha field and a submit button:
def form():
from gluon.tools import Recaptcha
form = FORM (
Recaptcha(request, public_key, private_key),
INPUT(_type='submit'))
if form.process().accepted:
response.flash = 'Thanks!'
elif form.errors:
response.flash = 'Invalid Entry'
else:
response.flash = 'No thanks!'
return dict(form=form)
I call it using {{=form}}
If I submit the Recaptcha field with nothing in there, it responds
immediately with an invalid submission. If I fill in anything in the
Recaptcha field (incorrect or otherwise), the browser just hangs there and
I have to reset the web server. I have checked communications between my
server and the Recaptcha server and it seems fine. Also, I have made sure
that I haven't mixed up any keys.
Has anyone else run into this issue recently?
Thanks,
Chris

[web2py] Re: Truncated Data on Migration
Derek, the main issue isn't truncation at insert time. In a web2py
DAL-mediated create table statement, DAL code unilaterally reduces MySQL
varchar lengths to 255, whether the specific version of MySQL could
tolerate a longer varchar or not. The developer says, column abc should be
varchar(1000); DAL runs the define_table; the resulting column is
varchar(255); no error is raised; developer has no reason to think there's
a problem; then inserts data and mySQL silently truncates (corrupts) it.
The DAL problem would be equally bad, although easier for the developer to
notice / and sooner, if MySQL didn't perform truncation. The fact that
MySQL performs truncation silently makes it that much more important that
DAL not change the column definition silently.
If I use the mysql command line tool, create table xyz (abc varchar(1000))
results in a column of length 1000. If I use the logically equivalent DAL
define_table statement, it results in a column of length 255. The two
approaches, given the same inputs, really should have the same outcome.
The behavior is also inconsistent among DB engines. For any DBMS other
then MySQL, DAL enforces a max varchar length of 2^15. However, Oracle 9i
has a max varchar length of 4000; SQL Server 2005 has a max of 8000; etc.
Many DBMS versions have some limit. In those cases, DAL attempts to
define the table per the developer's instructions and returns a
DBMS-specific error if a column length is unacceptable. The same should be
done for MySQL.
The correct behavior is to return an error if the developer issues a
define_table statement that can't be fulfilled by the database layer.

Setting a field's writable attribute to False prevents users from

In my ideal situation, when a user registers, they create a team name

added to the the t_teams table which contains a field for their team name
and their status on all of the challenges.
Now that I'm explaining it -- perhaps the 'right' solution is to just
add the extra fields to the auth_user table and not bother with having a

[web2py] Re: Referencing auth_user custom field in another table
So I'm stuck again and once again -- appreciate any help. What I'm doing
it pretty simple, I think. The code runs fine -- no error messages, but
the field isn't updated as I expect. So something is borked. flag
contains an integer from 1-16. The field in the db is called f_chal1,
f_chal2, etc.
def update_scoreboard(flag):
team = auth.user.id
print flag
print team
challenge = 'f_chal' + str(flag)
print challenge
row = db(db.auth_user.id == team).select().first()
db.auth_user.challenge.writable=True
print row
row.challenge = True
row.update_record()
db.commit()

Let me try again to explain what I'm striving for and see if that helps you
guys help me. I'm really trying to explain as concisely as possible,
without explaining the nitty gritty of what I'm trying to do.
In my ideal situation, when a user registers, they create a team name as
part of the registration process. When registration occurs a row is added
to the the t_teams table which contains a field for their team name and
their status on all of the challenges.
Now that I'm explaining it -- perhaps the 'right' solution is to just add
the extra fields to the auth_user table and not bother with having a
secondary table.

Sorry - it is a one to one relationship. So if I include it as part of the

need to figure out how to do that.

One thing that bugs me is that jQuery returns jQuery objects not dom
objects, so certain things you want to do just don't work if you treat it
like regular JS.
You can access the DOM object very easily by appending '[0]' to the jQuery
object.
For instance, $('#element')[0] will return the DOM element with the id of
element, or jQuery('a[href=#]')[0] will return the first anchor tag
with a href of #.

Your date has passed, so I don't know how useful this will be, but when I
introduce people to jQuery, I usually start with fun, gimmicky things, like
changing all the images in a web page to photos of cats:
jQuery('img').each(function() {var my = jQuery(this);
my.attr('src','http://www.placekitten.com/'+my.width()+'/'+my.height())})
And then move on to show how jQuery enables you to interact with things on
the page, like fading things in and out, resizing things, recoloring
things, and then using mouseovers or clicks to trigger these things on
other objects.
You could also show jQuery getting twitter updates.

[web2py] Re: Truncated Data on Migration
It would probably be difficult to keep DAL up to date with DBMS releases -- would hate to have to rev some part of web2py every time even one of the supported DBMSs has a version change. And even then, version alone may not answer the question, since max field lengths can be affected by database configuration options as well. A better solution would be for DAL to probe the actual DBMS capabilities -- if there is a question about an issue like a max string length, allow DAL to control one table (dbms_capabilities?) that can be used to test actual limits. E.g. if a DB model file specifies a string field of length 8000 and that is above the previously-tested limit, drop and create dbms_capabilities with a string(8000) field, write 8000 characters to it, read it back, and see if the result matches the input. This would be a very thorough way to find the limits of any database exactly as configured. Not sure if this would be needed for other data types too (decimal precision or ??) but could be generalized. The original problem of silently accepting a database definition that the DBMS can't produce is really concerning.
