Re: QSoapService Verification using Constructor

stromee — Wed, 20 Aug 2008 10:08:49 CDT

Unfortunately I'm still working on this. If I haven't been clear as of yet, here's simply my question:

How can I pass in an argument to the SoapClient constructor so I can process that variable in QSoapService?


$strApiKey = '123456789';
$objClient = new SoapClient($strWsdlUrl, $options, $strApiKey);

The above doesn't work. I have also tried:


$options['api_key'] = '123456789';
$objClient = new SoapClient($strWsdlUrl, $options);

But I am unable to access $options['api_key'] on the QSoapService side. For some reason it doesn't pass in the full $options array.

And here is my QSoapService:


class ProductService extends QSoapService {
        
        // This is used for validation
        protected $objSite;

        public function __construct($wsdl, $options) {
            parent::__construct($wsdl, $options);
            $this->objSite = Site::LoadByApiKey($options['api_key']);
        }
      }

As you can see, I need to load my Site object based on the ApiKey variable. However, I can't figure out how to pass that variable in...I have also created a separate function where I can pass the api key like so:


/**
         * Authorizes via API KEY
         * 
         * @param string $strApiKey
         */
        public function Authorize($strApiKey) {
            $this->objSite = Site::LoadByApiKey($strApiKey);
        }

This works, and I am able to pass in the $strApiKey, however, I am unable to use my $this->objSite object in any other functions within the class.

I am definitely missing something here. Can anyone help please?

Thanks much,
Chris

This is my solution, to try to modularise it to some extent. It is hardly robust yet but it works well thus far and no more of the errors I was recently receiving.

To use, in your panel which is to despatch events, simply

protected $objActionHandler; in your class members definition
$this->objActionHandler = new ActionHandler(); in your constructor
then create methods such as

public function SetExitAction($objCallbackTarget, $strCallbackTargetMethod) {
$this->objActionHandler->AddHandler('Exit', new ActionCallback($objCallbackTarget, $strCallbackTargetMethod));
}

then in your actul event trigger such as

public function btnExit_Click() {
$this->objActionHandler->Despatch('Exit', $arg1, $arg2 etc);
}

the 'Exit' is simply the event name, thus the Actionhandler instance can handle multiple events. The Despatch method is multiple argument capable, so just put whatever you want in there and it will get called into the callbck methods.

Enjoy

Please read the wise words of Mr Richard Stallman with regard to the MIT vs GPL debate:

http://www.gnu.org/philosophy/x.html

I respect the choices of others not to use the GPL. If Eric chooses GPL, then that choice should be respected. I believe that it is with some consideration that he has chosen this license over XFree86 license. If that means that you cannot use the software, then consider that there could be something wrong with your own licensing choice rather than his.

I have very limited spare time, but this looks a very worthwhile project. Well done Erik.

Hey Geert,

hadn't looked at the code yet, but your reference looks simple enough to add additional languages indeed. The cool thing about the library is that it refreshes the timestamps continuously once the page has loaded, but the recalculation is done completely on the client-side, avoiding load on the server-side.

How does the rest feel about this?

            $pnlBusinessCreateNew->SetCreatedAction(new QAjaxControlAction($this, 'BusinessViewEdit'));
            $pnlBusinessCreateNew->SetCreatedAction(new QTerminateAction());
            $pnlBusinessCreateNew->SetCancelNewAction(new QAjaxControlAction($this, 'BusinessList'));
            $pnlBusinessCreateNew->SetCancelNewAction(new QTerminateAction());
        }
        
        public function BusinessViewEdit($strFormId, $strControlId, $strBusinessId) {
            $this->RemoveChildControls(false);
            
            if (!$strBusinessId) $strBusinessId = QApplication::$Database[1]->InsertId();
            
            $objBusiness = Business::Load($strBusinessId);
            $pnlBusinessViewEdit = new BusinessViewEditPanel($this, $objBusiness);
            $pnlBusinessViewEdit->SetExitAction(new QAjaxControlAction($this, 'BusinessList'));
            QApplication::ExecuteJavaScript('$("#businessTabPanel ul").idTabs()');
        }
    }

The two functions which allow setting of action handlers inside the BusinessViewEditPanel are


public function SetCreatedAction(QAction $objAction) {
            $this->btnSave->AddAction(new QClickEvent(), $objAction);
        }

and


public function SetCancelNewAction(QAction $objAction) {
            $this->btnCancel->AddAction(new QClickEvent(), $objAction);
        }

Now what happens is, when I click the save button, the BusinessViewEditPanel method gets executed and the panels come up fine, then it seems to get run a second time and obviously it all goes pear shaped from there since the second running of the same action has no parameters or anything of the sort. I am 100% sure I am double clicking the button and besides, I have a QToggleEnableAction to prevent this.

I am not an advocate for the whole callback method since it requires a lot of coding to do something the whole action system should already provide not to mention I have great flexibility with this system.

Help would be greatly appreciated

I've posted my third episode. This one will be especially dull for people who aren't brand new to the framework, because it is just showing off the form drafts. The next episode will start getting more interesting again because the actual programming will begin. I plan to flaunt the meta-controls extensively, because I think it is one of the things Qcodo does better than all of the rest.

Re: QEmailServer with cURL?

Jandal — Tue, 19 Aug 2008 22:32:11 CDT

Hey Guys,

I'm in need of some help in regard to the Qcodo QEmailServer class.

My host has disabled anything to do with "allow_url_fopen" and "fsockopen" has apparently become part of that.

They recommend we now use cURL. This has come as a bit of a surprise and I'm left in the lurch a bit.

I will start having ago at rewriting this class but I don't think my skills will produce the best of results.

Just wondering if anyone else has come across this issue and perhaps already written something that works well and fits in line with Qcodo?

Thank you,
=-)

Thanks Vass, I shall check out the settings for php.ini.

Re: Version differences with same version number

Vass Arpad — Tue, 19 Aug 2008 08:07:01 CDT

Hi,

I think the version number difference is because of your php.ini settings regarding to the short_open_tag = On/Off,
Because in the index.php the version is printed this way:


Qcodo Development Framework ; ?>

for hte function generation, i guess , you did not set an index for the Advertised column.

the functions LoadArrayBy...As... LoadBy...As... are mostly generated for the indexes.

hope this helps you,

kind regards.

and


/core/includes/panelbase_classes_generated/

have disappeared! They no longer appear in the configuration file and nothing is being generated in them. I have currently emptied those two folders by simply deleting the files in them, and nothing is being written there when I run a codegen.

Re: ExpandAsArray and limit

Ago Luberg — Mon, 18 Aug 2008 15:09:08 CDT

Well, to think about it, then yes, it's not an easy task to come up with such a query.

Although I did one quick try. It's basically something like that:


select * 
from a
left join b on a.a1 = b.b1
-- one where filter to demonstrate
where a.a2 = 200 

and a.a1 in
  (select a1 from
    (select distinct a.a1
    from a
    left join b on a.a1 = b.b1
    -- the same filters here
    where a.a2 = 200)
  where rownum < 10);

As you may figure out, I used oracle to do this. And this one here is not tested query. My original query (which I tried it on) was somewhat more complex and may-be wouldn't give clean example. Anyway, as you can see, the main query part is duplicated here with filters. I'm not sure how it works on different filters/clauses (group by, count, virtual nodes).

And well, in my case I was able to remove most of the filters from the second "in" query, cause those were not necessary. But anyway, in SQL is is possible. I'm not sure how easy it would be to implement in QQuery.

When executing this on oracle, time difference wasn't significant. The given query was about 20% slower than usual query (without this "in" part). Although, query plan showed that "distinct" makes it "slower". At least in my case. May-be if there are indexes and stuff, it would be so hard?

Anyway, I'm not sure, whether I'd use 2 queries (one with limit,offset and other with expand as array joins) or 1 query to get this done as a manual query. I think the time difference isn't huge, so 2 queries might be easier. But it might be worth discuss it further.

And I'm not sure my suggestion about the query was the best way to do it. It just was the first one I got. May-be some clever counting would help. Count distinct object id-s and limit,offset by those.

Re: ExpandAsArray and limit

VexedPanda — Mon, 18 Aug 2008 13:41:31 CDT

Basically, I think the limitation is SQL itself. How would your manual query accomplish this? Until you query the DB, how do you know how many elements the expanded array will contain?

If you're doing multiple DB hits to discover this information, why not make things easier, and just use the multiple hits to load the relevant arrays later instead?

Re: ExpandAsArray and limit

Ago Luberg — Mon, 18 Aug 2008 12:53:06 CDT

Has anyone tried to do something with ExpandAsArray and tried to limit the results to say 10 items per page?

The problem is, that generated SQL has probably more rows than objects it generates. For example, I have 10 objects, each of them has 3 associations which I expand as array. When querying all, the results are fine. But when I want to have 5 first objects (meaning 5 * 3 rows from database), I don't get the desired result.

I know, what are the limitations of qquery and sql in this case. Just wanted to know, whether someone has a clever solution for this?

I probably can have manual query, which is fine. Though I'd like to populate ORM objects. I know it's doable, though it needs a lot of work (I assume I can't call InstantiateDbRow just like that).

Other possibility would be using virtual node to gather my information into comma separated list or something. Again, ORM object will not be filled (though it's better than the first solution which has no ORM objects at all).

Or some elegant solution to add into datagrid or something. Basically what's needed, is to count distinct objects (id's of them for example) you are querying by. For example if you use MyObject::QueryArray, then count(my_object.id) could by used to know, what to query. Though it's more tricky to have "limit,offset" version of this. Some subqueries are needed etc.

Does anyone have a better solution or tried something like this? May-be it's easier to have manual query working with datagrid?

Though this solution (if working with qquery) could be useful for many others.. If there is not one yet :P

Re: QSoapService Verification using Constructor

stromee — Mon, 18 Aug 2008 10:44:01 CDT

Still haven't figured this out. Basically, what I need to do is store the objSite object when creating a SoapClient based on an api_key to use that throughout for verification.

What's the best way to pass in another parameter into the __construct of QSoapService? Or is this not possible?

Thanks much,
Chris
