I'm using web2py forms, but I need to set up a limit for 20 users registration. How can I do it?
PS: Edit to make easy to understand
Thanks in advance.
Best regards!
Assuming you wish to limit registration to a maximum of 20 users and you are using the standard /default/user function from the scaffolding application:
In the default.py controller:
def user():
if request.args(0) == 'register' and db.auth_user.count() >= 20:
form = None
else:
form = auth()
return dict(form=form)
In the default/user.html view:
{{if form is None:}}
<p>Sorry, no more registrations allowed.</p>
{{else:}}
{{=form}}
{{pass}}

I am trying to implement a security rules function that will work with custom claims. depending on the custom claim case it will return a chunk that represent the security rules for the current related case at hand that will represent the state that user is currently in current code looks like this.
// fn arg
// request.resource.data
// request.auth.token.userPlan
function userPlanChecker(requestData, userPlan) {
return (
// max 25 related clients
(userPlan== 'basic' && requestData.clients.size() <= 25) ||
(userPlan== 'pro' && requestData.clients.size() <= 50) ||
(userPlan== 'ultimate' && requestData.clients.size() <= 75)
)
}
the idea is to use custom claim case name to return the current limit on the array size, thus allow more control over limitation of how many clients a user could have. ?

You are getting the error because you are trying to pass an uninitialized String to a Text-Widget (Naber). A Text-Widget can not handle uninitialized Strings which have the value null. Therefore try initializing the String 'Naber' directly like: String Naber = 'Some text'; This should work.

I am using Mojolicious Perl framework in my application. I want to store an array in session, but is not successful.
my #returnResult;
$returnResult['fn'] = $decoded->{'fn'};
$returnResult['ln'] = $decoded->{'ln'};
$self->session(returnResult => #returnResult);
Please help.
See hashes in Modern Perl and perldata.
my %return_result;
$returnResult{fn} = $decoded->{fn};
$returnResult{ln} = $decoded->{ln};
or
my %return_result = (
fn => $decoded->{fn},
ln => $decoded->{ln},
);
or simply
# http://perldoc.perl.org/perl5200delta.html#New-slice-syntax
my %return_result = %$decoded{qw(fn ln)};
You do not get automatic references like in other languages. Use the \ operator.
$self->session(returnResult => \%return_result);
What text (in English) should I use when asking the user to overwrite a document? [closed]

Closed 7 years ago. Improve this question I write a lot of applications in C# and I'm trying to sew up some holes in my standard practices. Specifically, I'm trying to decide on the best text to use in a message box, and I thought I'd ask the StackOverflow community since I believe that many opinions are always better than one. What I have currently is: "Document XXX.docx already exists. Okay to overwrite?" Buttons for; Yes, No and Cancel I'm really interested to see which examples turn out to be the most popular. There are no limits on the style used; formal, casual, humourous, etc. All suggestions are welcome. Aim to err safely within political correctness though. On a small side note: It would also be great, but by no means essential, to consider that the same text could also be suitable for a command line program. Please note: English language only please. For other languages, please raise a new question.
Personally, I like to see a bit more context and slightly different wording. Something like: "<existing document name>" already exists in "<destination path>". Would you like to replace it (Y/N)? or perhaps with even more information: "<existing document name>" (<bytes>) (<date modified>) already exists in "<destination path>". Would you like to replace it with file of size <new bytes>, last modified <new date modified> (Y/N)? I think "replace" is a bit more clear than "overwrite" - and (speculation) may translate into other languages, and maintain the intended meaning more often. ...and one last option with new file name/location info: "<existing document name>" (<bytes>) (<date modified>) already exists in "<destination path>". Would you like to replace it with file "<new file name>" in "<new path>" of size <new bytes>, last modified <new date modified> (Y/N)? This last one would probably just show a temp file / buffer location for an initial file save--but it is reusable, and more meaningful when doing a file copy. Hope you find one of these useful. Cheers, Hans

Simple solutions are usually best, for example windows user might find it familiar to see a message : He has 3 options : Replace Abort action x3 Create with a new name

The simplest way would be to reshape the matrix and use it accordingly. I demonstrate the way to reshape and print all the dates in US (MM/DD/YYYY) format.
X=[2014,01,02 2014,01,03 2014,01,07 2014,01,08 2014,01,09 2014,01,10 2014,01,13 2014,01,14 2014,01,15 2014,01,16 2014,01,17 2014,01,20 2014,01,21 2014,01,22 2014,01,23 2014,01,24 2014,01,27 2014,01,28 2014,01,29 2014,01,30 2014,01,31 2014,02,03 2014,02,04 2014,02,05 2014,02,06 2014,02,07 2014,02,10 2014,02,11 2014,02,12 2014,02,13 2014,02,14 2014,02,17 2014,02,18 2014,02,19 2014,02,20 2014,02,21 2014,02,24 2014,02,25 2014,02,26 2014,02,27 2014,02,28 2014,03,03];
