Re: [Catalyst] Using Jquery UI Autocomplete widget with Catalyst::View::JSON
Dear Rodrigo
I tired your tip, but my response is:
{json:[{value:Paddyfield Warbler,label:Paddyfield
Warbler,id:Acrocephalus agricola}]}
and -of course- there is no any suggest. :(
I thought that Catalyst::View::JSON translate perl datastructures to
corresponding JSON data structure ( hash object ... as i see on
http://www.json.org) automatically. ( if not, i could use manually
created JSON formatted string without any JSON module)
Thank You!
Have you tried this?
sub request : Local {
my ($self,$c) = @_;
$c-stash-{json} = [ { id=Acrocephalus agricola, label=
Paddyfield Warbler, value= Paddyfield Warbler } ];
$c-forward('View::JSON');
}
It gives me back the following response:
$ curl http://localhost:3000/request http://localhost:3000/test
[{value:Paddyfield Warbler,id:Acrocephalus
agricola,label:Paddyfield Warbler}]
Which works with JQuery's autocomplete example just fine

Re: [Catalyst] Using Jquery UI Autocomplete widget with Catalyst::View::JSON
Looks like you need to set
expose_stash = 'json'
in your config.

Re: [Catalyst] Using Jquery UI Autocomplete widget with Catalyst::View::JSON
Dear Ben van Staveren Thank You, now it is working, but in this case, i don't know why to use Catalyst::View::JSON, it is just a text formatting. Later I'd like to use DBIx datasource to feed autocomplete plugin, in this case i must manually build a special JSON formatted string. Is there exist a better way? Thank You!

Re: [Catalyst] Using Jquery UI Autocomplete widget with Catalyst::View::JSON
Ahh!
That was the trick :)))
(expose_stash = 'json')
Now it is correctly translate the perl arrayref datastructure to JSON
array ( [ ... ] )
my @aoh = (
{
value = 1,
label = betty,
},
{
value = 2,
label= jane,
},
{
value = 3,
label= marge,
},
);
$c-stash-{json} = \...@aoh;
$c-forward('View::JSON');
:)
Thanks Ben!
One last question: if I have a DBIx resultset, how to use it to
populate autocomplete with the easiest way?
Best wishes from Hungary!
Ben van Staveren írta:
You can do that with View::JSON :) Just read the docs though, the reason
it didn't work is that you put your data in
$c-stash-{json} = [ ... ]
And View::JSON will attempt to turn your entire stash into JSON data :)
And it does that bit correctly, but the thing you end up with is
{
json: [ ... ]
}
And autocomplete doesn't like that. So, either do:
$c-stash([ ... ])
Or set the expose_stash setting. Whatever is set in there, is the only
thing that View::JSON will attempt to serialise.
Personally I prefer expose_stash = 'json', so that anything under
$c-stash-{json} is serialised, but up to you :)

Re: [Catalyst] Using Jquery UI Autocomplete widget with Catalyst::View::JSON
Probably not the most pretty one but:
Given you have a resultset obtained with, say,
my $result_set = $c-model('DB::Somedata')-search_rs({...}, {...});
$c-stash-{json} = [
map { id = $_-id, label = $_-name } ($result_set-all)
];
Or a bit more verbose:
foreach my $result ($result_set-all) {
push(@{$c-stash-{json}}, { id = $result-id, label = $result-name });
}

I've also had good luck using DBIx::Class::RsultClass::HashRefInflator
in the past. It doesn't give you quite as much control, but it may be
enough for your needs.

Re: [Catalyst] Using Jquery UI Autocomplete widget with Catalyst::View::JSON
Used it but at the same time, doing my $hashref = { $row-get_columns }
got me more or less the same effect for a lot less hassle :)
I actually do this for most my DB objects that get serialised to JSON,
quite simple case of $c-stash-{json} = [ map { $_-get_columns }
$rs-all ];
In a similar vein, I haven't yet really seen/heard any sort of best
practices when it comes to Catalyst and JSON, so maybe I'm going about
it all wrong but eh :)

HRI will return prefetched rels too, get_columns won't.

[Catalyst] Using Jquery UI Autocomplete widget with Catalyst::View::JSON
Dear All
Is there anyone, who has success with this combination?
I have no idea, how to use this.
On the Jquery Autocomplete demo page, i 'd like to do as you can see in
the second demo
(Remote datasource), but not working.
If examine the original demo response with firebug, i see, that the
'search.php'
(which is used in the demo as a remote datasource) response is HTML header
and NOT JSON, and it is working.
If i changed to my own response generated with C:W:JSON, i see the
correct type:
JSON, but there is no suggestion appears.
I noticed, the Autocomplete plugin waits for String-Array or
Object-Array, (which
starts and ends with [ ...] ) but my code always starts and ends with {
... } (JSON object type).
I tried many perl data-structure, but always starts with { ...
Original working response (with HTML header):
|[ { id: Acrocephalus agricola, label: Paddyfield Warbler, value:
Paddyfield Warbler } ]
My not woking response with JSON header:
||{value:Common Shelduck,id:Tadorna tadorna,label:Common Shelduck}|
Thank you in advance!!
