I am trying to understand how to access dynamics enums to be able to pass these into BusinessConnector calls. For instance, you can call the following:
pobj = (AxaptaObject)ax.CreateAxaptaObject("PurchFormLetter", [ENUM]);
But, I have no idea how to pass in the correct value of [ENUM]. In X++, the enum is DocumentStatus::PurchaseOrder, but I don't seem to be able to access this from anywhere. Can anyone possibly assist in finding out how to pass in the value?
Passing in the numeric value of the enum does not work unfortunately (in this case the value I need is 2). It returns an XPPException of 'Function PurchQuantity::construct has been used incorrectly.'
AxaptaObject pobj = (AxaptaObject)ax.CreateAxaptaObject("PurchFormLetter", 2);
If anyone could please be of assistance that would be greatly appreciated.
Regards,
Steve
Others have the same problem. And they have found a solution by creating an enum proxy.
Ok, this is for everyone else who hits this problem:
If you want to access the enum values from .NET purely without using X++:
string enumName = "DocumentStatus", enumValue = "PurchaseOrder";
object enumObj = (int)axa.CallStaticClassMethod("Global", "enumName2Id", enumName);
AxaptaObject dict = (AxaptaObject)axa.CreateAxaptaObject("DictEnum", enumObj);
object res = dict.Call("symbol2Value", enumValue);
The above can be made into a function very easily if reuse is required.
Still, doing the following won't work:
AxaptaObject pur = (AxaptaObject)axa.CreateAxaptaObject("PurchFormLetter", res);
However, you can do it this way:
AxaptaObject pur = (AxaptaObject)axa.CallStaticClassMethod("PurchFormLetter", "construct", res);
This will allow you to pass in the integer value of the enum (in this case, the variable 'res'). You can then use this object to post the purchase order.
Hope this helps someone.

Steve

I am currently coding a plugin for ILIAS. The plugin itself is not at all complex but it contains several issues whereas I think we could make it simpler as it is.
The situation is following: We have a global advanced meta data field added in the user defined meta data section with a bijective identifier. The field is activated at a repository objected named course. We have manipulated the GUI with the plugin based on ilUIHookPluginGUI.
The code for this is ... well ... see it for yourself.
First of all we save the ID of the new meta data field in the settings at the ConfigGUI for the plugin:
$field_settings = new ilSetting("foo");
$field_id_value = $field_settings->set("field_id",$_POST["field_id"]);
In our class which extends ilUIHookPluginGUI we are loading the setting as following and we have the ID of the field:
$field_settings = new ilSetting("foo");
$field_id_value = $field_settings->get("field_id");
Now the fun part. With this ID and the ref_id of the object (well, we also load the object to get the ObjId) we can load the value of the meta data field setted at the course:
$object = \ilObjectFactory::getInstanceByRefId($_GET[ 'ref_id' ]);
$obj_id = $object->getId();
$result = $DIC->database()->query("SELECT value FROM adv_md_values_text WHERE obj_id = '".$obj_id."' AND field_id = '".$field_id_value."'");
$value = $DIC->database()->fetchAssoc($result);
$is_active = $value['value'];
The question is ... is there an easier way to achieve my result?
Best,
Laura
Nice question. First of all, note that I consider the advanced metadata service in ILIAS to be lacking a good readme making clear, which hooks the interface is offering for tasks such as yours. Some time ago, I had to deal with this service as well and run into similar issues. Hopefully, your question helps to document this a little better an I myself am looking forward to other suggestions, knowing that mine is not really good as well. If you have any resources, helping pushing the introduction of good readme for services and also pushing services towards using the repository pattern with a clear interface would be highly appreciated.
Concering your question of what can be improved: I see three main issues in the lines of code:
Storing an ID in the config of your plugin. Your plugin will unconfigurable for non-technical people. However, also for you this will be error prone, think about exporting-importing stuff from a test-installation to production.
Access the value by query instead of the service.
Using new and static functions inside your code making it untestable.
Step 1
Lets start with the first one. Note, that I did not manage to solve this one without introducing a new one (a new query). Bad I know. I hope that there is a better solution, I did not find one after quick research. You store the id, since the field title is not securely unique, right? This is correct, however, you could think about storing the tripplet of field_title, record_title and (maybe) scope. Note that you maybe do not need the scope since you want to use this globally. A function return you and array containing field_id and record_id could look like so:
function getFieldAndRecordIdByFieldTitles($field_title, $record_title, $scope_title){
$query = "select field.field_id,field.record_id from adv_mdf_definition as field
INNER JOIN adv_md_record as record ON record.record_id = field.record_id
INNER JOIN adv_md_record_scope as scope ON scope.record_id = field.record_id
INNER JOIN object_reference as ref ON scope.ref_id = ref.ref_id
INNER JOIN object_data as scope_data ON ref.obj_id = scope_data.obj_id
WHERE field.title='$field_title' AND record.title='$record_title' AND scope_data.title = '$scope_title'";
$set = $this->dic()->database()->query($query);
if($row = $this->dic()->database()->fetchAssoc($set))
{
return array_values($row);
}
}
Then get your values like so:
list($field_id,$record_id) = getFieldAndRecordIdByFieldTitles("my_field", "my_record", "my_scope");
Note that I am aware that I am introducing a new query here. Sorry, was the best I could come up with. I am sure there you find a better solution, if your research a bit, let us know if successful. However, we will remove one in the next step.
Step 2
Use the undocumented service, the get your value out of the advance meta data. Since you now have the record id and the field id, you can to that like so:
$record_values = new ilAdvancedMDValues($record_id, $obj_id);
$record_values->read();
$ADTGroup = $ilAdvancedMDValues->getADTGroup();
$ADT = $ilADTGroup->getElement($field_id);
$value = $ADT->getText();
/**if you have text, others are possible, such as:
switch (true) {
case ($ADT instanceof ilADTText):
break;
case ($ADT instanceof ilADTDate):
$value = $ADT->getDate();
break;
case ($ADT instanceof ilADTExternalLink):
$... = $ADT->getUrl();
$... = $ADT->getTitle();
break;
case ($ADT instanceof ilADTInternalLink):
$... = $ADT->setTargetRefId($value);
}
**/
Note that ADT's are also undocumented. There might be a better way, to get a value out of this.
Step 3
Wrap your statics and new into some injectable dependency. I usually use the bloated constructor pattern to do this. Looks like so:
public function __construct(InjectedSettings $mySettings = null)
{
if (!$mySettings) //Case in the default scenario
{
$this->mySettings = new InjectedSettings();
} else //used e.g. for unit tests, where you can stuff the constructor with a mock
{
$this->mySettings = $mySettings;
}
$this->mySettings->doSometing();
}
Note that this is not real dep. injection, still you still use new, but I think a very workable fix to use dep. injection at least for the test context in ilias.
Does this help? I hope there will be other (better answers as well).
Is there is any way to Shortcut this Code
$questions = $this->getdoctrine()->getrepository('AppBundle:TicketQuestions')->find($id = 1);
$question1 = $questions->getQuestions();
$option1 = $questions->getOption1();
$option2 = $questions->getOption2();
$option3 = $questions->getOption3();
Because i want to use more than 20 times.
i use this code to get some questions and options from database for a Ticket system and i hope there is a way to not write a very long code for that.
It's hard to say without seeing your Entities. For example, do you have 20 hardcoded "options" in your "Questions" entity?
If you were to use something like an array of options, you could just use a foreach loop and get all those options. But, that also has some foundation in what your data model looks like.
If you want to use an underlying datastructure (such as an array or Doctrine ArrayCollection) you'll first have to structure your database and data scheme with the correct architecture.
This is a much deeper question than can you just write a shortcut, I don't think your underlying data and architecture are implemented correctly to use data structures (array, ArrayCollections).
Thanks any way guys, i solved it like this -> i wrote new function
public function callQuestions($id){
$questions = $this->getDoctrine()->getRepository('AppBundle:TicketQuestions')->find($id);
$question = $questions->getQuestions();
$option1 = $questions->getOption1();
$option2 = $questions->getOption2();
$option3 = $questions->getOption3();
return array($question,$option1,$option2,$option3);
}
and now i can call it easily like this:
$firstQuestion = TicketsController::callQuestions(1);
i will try also to make it shorter but this one works good now.
Here's what I'm trying to do:
IEnumerable<OfficeView> allOffices = GetAllOffices(); //this method also uses some linq query
foreach (var office in allOffices)
{
officeSales.Add(
new Tuple<int, decimal>(office.Id, GetSaleAmount(office.Id, someParams)));
}
public decimal GetAgentSaleAmount(int officeRef, someTypes someParams)
{
var q = ObjectQuery.Where
(i => i.officeId == officeRef && i.someOtherStuff == someParams)
.ToList();
return q.Sum(i => i.NetPrice);
}
I can't set MultipleActiveResultSets = true. Instead, as suggested here, I tried to do .ToList() before doing the summation, but got the same error. (and even if I wouldn't get the error, I think it would cause heavy load to fetch everything just to get the summation of one field)
I will be super thankful for any suggestion to solve this problem!
Update: The problem was all about GetAllOffices(), which returned IEnumerable (which leaves the DataReader open). I changed the first line as below and it worked. Thanks a lot guys :)
IEnumerable<OfficeView> allOffices = GetAllOffices().ToList();
Error said that reader is already opened, that means that you have run some query before which needs to close.
Write .ToList() to that linq query and do same for other queries too.
I think you are trying to do both adding and querying at the same time.You need to finish adding "Sale" object to "Sales" collection before trying to calculate the sales value.
In other words, you cannot query until the transaction is committed. Hope that helps.
I've got a JObject (using JSON.Net) that I created by parsing some JSON text. I'm directly manipulating, adding keys at the top level of this JObject. I have no problems when the value I'm adding is a string:
json["newkey"] = "New Value"; // works
But I'll be damned if I can figure out how to add a Dictionary, e.g.:
Dictionary<string,string> dict = new Dictionary<string,string>();
dict["one"] = "1";
dict["two"] = "2";
json["dict"] = dict; // fails
I've done quite a bit of googling and reading the JSON.Net docs, but everything seems oriented towards reason JSON text into a JObject, or writing .NET objects as JSON text using serialization. Or using some fancy LINQ statements to do all kinds of things with complex objects...
I've tried these and none have worked:
json["dict"] = new JObject(dict);
json["dict"] = new JObject((Dictionary<string,string>)dict);
json["dict"] = new JArray(dict); // desperation sets in :)
json["dict"] = (JObject)dict; // please dear god let this work
Most of the latest errors I encounter are:
Could not determine JSON object type for type System.Collections.Generic.KeyValuePair`2[System.String,System.String].
I believe that you are looking for something like this:
json["dict"] = JObject.FromObject(dict);
There is a desperate "hack" that you can use, it's not pretty (doing twice the same thing) but it works :)
json["dict"] = JObject.Parse(JsonConvert.SerializeObject(dict));
Afternoon,
I am getting the following error, and cant work out why... Can some one please take a look and let me know where i am going wrong.
Cannot implicitly convert type 'System.Collections.Generic.List' to 'System.Collections.Generic.List'
below is what i am trying to use, to get a list back so i can use it with Amazon. I have tried to remove the .ToList() bit but nothing seems to work. I am calling an MS SQL view "GetASINForUpdateLowPrices" which returns a list back of product ASIN's
List<string> prodASINs = dc.GetASINForUpdateLowPrices.ToList();
SQL for the view i am using, this may help a little bit more.
SELECT asin
FROM dbo.aboProducts
WHERE (asin NOT IN
(SELECT aboProducts_1.asin
FROM dbo.aboProducts AS aboProducts_1 INNER JOIN
dbo.LowestPrices ON aboProducts_1.asin = dbo.LowestPrices.productAsin
WHERE (dbo.LowestPrices.priceDate >= DATEADD(day, - 1, GETDATE()))))
What data type is a single ASIN?
Probably your GetASINForUpdateLowPrices is not an IEnumerable<string>. Try this to confirm:
List<string> prodASINs = dc.GetASINForUpdateLowPrices
.Select(e => e.ToString())
.ToList();
When you call your GetASINForUpdateLowPrices, it wont directly return List<string> even if there is only one field in your view. Try the following approach:
List<string> prodASINs = dc.GetASINForUpdateLowPrices
.Select(item => item.AsinFieldName)
.ToList();
Visual Studio IntelliSense should suggest you the property name after typing item.. If the property is not string try to add .ToString() at the end of the property name.
Edit: After your comment, it seems like you need to use it as .Select(item => item.asin.ToString()).
Just use var.
var prodASINs = dc.GetASINForUpdateLowPrices.ToList();
Are you sure that GetASINForUpdateLowPrices.ToList() creates a List of Strings? My best estimation is that it is a generic list of a different type.
To figure out what is going on - Change List<string> prodASINS to be Object obj. Then set a breakpoint to see what List type is actually generated by your ToList() code by checking out the object using the debugger. You can then update your code to move the values into a list of the appropriate type.
You might have to cast the right side of the assignor like this to ultimately get the job done (replacing string with another type if necessary) - List<string> prodASINs =(List<string>)dc.GetASINForUpdateLowPrices.ToList()
