Re: [Catalyst] transforming empty values in request to perl's undef

2017-03-02 Thread Rajesh Kumar Mallah


By empty i mean string with length 0 ie ''

__CODE__


I am posting to rest endpoint Automagically generated via
Catalyst::Controller::DBIC::API  there is no explicit code hand
written by me.And that is why looking for a global filter.

There are three great virtues of a programmer; Laziness, Impatience and
Hubris -- Larry Wall.

[Catalyst] transforming empty values in request to perl's undef

2017-03-02 Thread Rajesh Kumar Mallah


Hi ,

I want to transform request parameters in GET & POST requests
so that any thing which is empty (string) gets converted/replaced
my perl's undef (and DBIC's NULL).

Why i need that:

I have edit form in my web app and some fields in the edit form
are prefilled with nothing. On submission the DB raises an exception
that an empty string is being inserted to a integer field.

Hence I feel like having a global filter that turns all blanks to
undef.

The question is where to put this global filter.

Regds
mallah.

Hi there, I had a Catalyst application working on a debian 7 perl 5.14 apache

I
did all the installation in the same way I did it for the old debian but the 
apache server is
not starting, and at the logs a get nothing but:

Re: [Catalyst] transforming empty values in request to perl's undef

2017-03-02 Thread Gil Magno

Hi

Are you by any chance using HTML::FormFu? If so, check the "ignore_if_empty" 
option.

https://metacpan.org/pod/HTML::FormFu::Model::DBIC#Config-options-for-fields

If not, could you please show the code with which you're "receiving" the params 
and inserting into the DB?

Just curious: when you say "prefilled with nothing", you mean the field is 
empty, or the field is filled with one or more white spaces (like " "), or the 
field is a  with the first  having the attribute "value" equals 
to ""? Or something else?
