I am just getting familiar with the StackMob server side custom code sdk and i am trying to get a relationship field and iterate through it in the form of a String array. How do i do that ? is it possble to iterate through it without parsing it into an array?
DataService ds = serviceProvider.getDataService();
List<SMCondition> query = new ArrayList<SMCondition>();
query.add(new SMEquals("product_id", new SMString(jsonObj.getString("product_id"))));
List<SMObject> results = ds.readObjects("product", query);
SMObject product= results.get(0);
//product.getValue().get("categories"); how do i get this to be a String array?
At its simplest, that would look something like this:
List<SMValue> categories = (List<SMValue>)(rawObj.getValue().get("categories").getValue());
for (SMValue smString : categories) {
SMString stringValue = (SMString)smString.getValue();
//do whatever you want with the string value here
}
Obviously there are some unchecked casts in here, so you will want to add type/null checking to the appropriate sections depending on your data & schema.

Below is the code written by my collegue who doesnt work in the firm anymore. I am inserting records in object with data loader and I can see success message but I do not see any records in my object. I am not able to understand what below trigger is doing.Please someone help me understand as I am new to salesforce.

You might be looking in the wrong place. Check if there's an unit test written for this thing (there should be one, especially if it's deployed to production), it should help you understand how it's supposed to be used.
You're inserting records of QMBDataLogging__c but then it seems they're immediately deleted in DeleteDoAsLoggingRecords.deleteTheProcessRecords(processdIds). Whether whatever this thing was supposed to do succeeds or not.
This seems to be some poor man's CSV parser or generic "upload anything"... that takes data stored in QMBDataLogging__c and creates QMB_Initial_Letter__c out of it.
QMBLetteTypeToVfPage__c.getAll() suggests you could go to Setup -> Custom Settings, try to find this thing and examine. Maybe it has some values in production but in your sandbox it's empty and that's why essentially nothing works? Or maybe some values that are there are outdated?
There's some comparison if what you upload into Field1__c can be matched to what's in that custom setting. I guess you load some kind of subtype of your QMB_Initial_Letter__c in there. Record Type name and list of fields to read from your log record is also fetched from custom setting based on that match.
Then this thing takes what you pasted, looks at the list of fields in from the custom setting and parses it.
Let's say the custom setting contains something like
Name = XYZ, FieldAPINames__c = 'Name,SomePicklist__c,SomeDate__c,IsActive__c'
This thing will look at first record you inserted, let's say you have the CSV like that
Field1__c,Field2__c,Field3__c,Field4__c
XYZ,Closed,2022-09-15,true
This thing will try to parse and map it so eventually you create record that a "normal" apex code would express as
new QMB_Initial_Letter__c(
Name = 'XYZ',
SomePicklist__c = 'Closed',
SomeDate__c = Date.parse('2022-09-15'),
IsActive__c = true
);
It's pretty fragile, as you probably already know. And because parsing CSV is an art - I expect it to absolutely crash and burn when text with commas in it shows up (some text,"text, with commas in it, should be quoted",more text).
In theory admin can change mapping in setup - but then they'd need to add new field anyway to the loaded file. Overcomplicated. I guess somebody did it to solve issue with Record Type Ids - but there are better ways to achieve that and still have normal CSV file with normal columns and strong type matching, not just chucking everything in as strings.
In theory this lets you have "jagged" csv files (row 1 having 5 fields, row 2 having different record type and 17 fields? no problem)
Your call whether it's salvageable or you'd rather ditch it and try normal loading of QMB_Initial_Letter__c records. (get back to your business people and ask for requirements?) If you do have variable number of columns at source - you'd need to standardise it or group the data so only 1 "type" of records (well, whatever's in that "Field1__c") goes into each file.
I've read all the documentation I can find and watched all the videos I can find and don't understand how to do this. I have set up an xPages REST Service and it works well. Now I want to place the results of the service into either a combobox or typeahead text field. Ideally I would like to know how to do it for both types of fields.
I have an application which has a view containing a list of countries, another view containing a list of states, and another containing a list of cities. I would like the first field to only display the countries field from the list of data it returns in the XPages REST Service. Then, depending upon which country was selected, I would like the states for that country to be listed in another field for selection, etc.
I can see code for calling the REST Service results from a button, or from a dojo grid, but I cannot find how to call it to populate either of the types of fields identified above.
Where would I call the Service for the field? I had thought it would go in the Data area, but perhaps I've just not found the right syntax to use.
November 6, 2017:
I have been following your suggestion, but am still lost as can be. Here's what I currently have in my code:
x$( "#{id:ApplCountry}" ).select2({
placeholder: "select a country",
minimumInputLength: 2,
allowClear : true,
multiple: false,
ajax: {
dataType: 'text/plain',
url: "./Application.xsp/gridData",
quietMillis: 250,
data: function (params) {
return {
search:'[name=]*'+params.term+'*',
page: params.page
};
},
processResults: function (data, page) {
var data = $.map(data, function (obj) {
obj.id = obj.id || obj["#entityid"];
obj.text = obj.text || obj.name;
return obj;
});
},
return {results: data};
}
}
});
I'm using the dataType of 'text/plain' because that was what I understood I should use when gathering data from a domino application. I have tried changing this to json but it makes no difference.
I'm using processResults because I understand this is what should be used in version 4 of select2.
I don't understand the whole use of the hidden field, so I've stayed away from that.
No matter what I do, although my REST service works if I put it directly in the url, I cannot get any data to display in the field. All I want to display in the field is the country code of the document, which is in the field named "name" (not my choice, it's how it came before I imported the data from MySQL.
I have read documentation and watched videos, but still don't really understand how everything fits together. That was my problem with the REST service. If you use it in Dojo, you just put the name of the service in a field on the Dojo element and it's done, so I don't understand why all the additional coding for another type of domino element. Shouldn't it work the same way?
I should point out that at some points it does display the default message, so it does find the field. Just doesn't display the country selections.
I think the issue may be that you are not returning SelectItems to your select2, and that is what it is expecting. When I do something like you are trying, I actually use a bean to generate the selection choices. You may want to try that or I'm putting in the working part of my bean below.
The Utils.getItemValueAsString is a method I use to return either the string value of a field, or if it is not on the document/empty/null an empty string. I took out an if that doesn't relate to this, so there my be a mismatch, but I hope not.
You might be able to jump directly to populating the arrayList, but as I recall I needed to leverage the LinkedHashMap for something.
You should be able to do the same using SSJS, but since that renders to Java before executing, I find this more efficient.
For label/value pairs:
LinkedHashMap lhmap = new LinkedHashMap();
Document doc = null;
Document tmpDoc = null;
allObjects.addElement(doc);
if (dc.getCount() > 0) {
doc = dc.getFirstDocument();
while (doc != null) {
lhmap.put(Utils.getItemValueAsString(doc, LabelField, true), Utils.getItemValueAsString(doc, ValueField, true));
}
tmpDoc = dc.getNextDocument(doc);
doc.recycle();
doc = tmpDoc;
}
}
List<SelectItem> options = new ArrayList<SelectItem>();
Set set = lhmap.entrySet();
Iterator hsItr = set.iterator();
while (hsItr.hasNext()) {
Map.Entry me = (Map.Entry) hsItr.next();
// System.out.println("after: " + hStr);
SelectItem option = new SelectItem();
option.setLabel(me.getKey() + "");
option.setValue(me.getValue() + "");
options.add(option);
}
System.out.println("About to return from generating");
return options;
}
I ended up using straight up SSJS. Worked like a charm - very simple.
I want to split the values selected from couch db in gwt according to a particular id. I tried to use the String tokenizer but couldn't found something useful. the result returned from couch db is in the following format:
{"_id":"2","_rev":"1-717f76046030a683687ace9ac8f7bdbf","course":"jbdgjbj","passwd":"rty","phone":"24125514444","clgnme":"bjfbjf","address":"jbjfbjb","name":"meenal","cpasswd":"rty","user":"2","fname":"jfbg"}
I just want to get the values and set them in textboxes.
how to do it?
try this ...
Session studentDbSession = new Session("localhost",5984);
Database studentCouchDb = studentDbSession.getDatabase("student");
System.out.println("select");
Document d = studentCouchDb.getDocument(input);
if(d.containsKey("FirstName")){
fname=d.getString("FirstName");//fname is variable
}
if(d.containsKey("LastName")){
lname=d.getString("LastName");//lname is variable
}
if(d.containsKey("Address")){
add= d.getString("Address");//add name is variable
}
finally concatenate all strings and return to client...
all=fname+" "+lname+" "+add;
return all;
This looks like JSON. You can parse it using JSONObject:
JSONObject obj = new JSONObject(yourString);
String course = obj.getString("course");
I have a form in as3 flash with textfields and radio buttons with their "instance name" all set consecutively such as:
field_1
field_2
field_3
...etc
Is there an easy way in AS3 code to loop over all those fields and get their values in an array? Ideally I'd like a simply loop to get the values (so I can add in a simple popup if a value is missing) and then with the filled array simply post it using URLRequest.
Thanks!
If you want a way that's a little less work and more maintainable (if the amount of text can change in the future or you need to reuse the code on other forms or don't want to bother with instance names), then you could do something like the code below.
Keep in mind this assumes all your text fields are children of the same parent and is in the scope of that parent (so on a frame in the timeline that holds all your text fields)
function validateTextFields(){
var tmpTf:TextField;
var i:int = numChildren;
while(i--){ //iterate through all the display objects on this timeline
tmpTf = getChildAt(i) as TextField;
if(tmpTf){
//now that you have the textfield, you can check for an appropriate value, or send the value to a server, or store it in an array etc.
//check if the value is blank, if so set the background to red
if(tmpTf.text == ""){
tmpTf.background = true;
tmpTf.backgroundColor = 0xFF0000;
}else{
tmpTf.background = false;
}
}
}
}
It sounds like you want to use a for statement. I've also used a multi-dimensional array to store the instance names, and the text that they contain. I like to use the variable _path to define the scope of my code.
var _path = this;
var text_ar:Array = new Array(['instance_1',''],['instance_2',''],['instance_3','']); //instance name, instance text.
for(var i=0; i<ar.length; i++)
{
text_ar[i][1] = _path[text_ar[i][0]].text
}
trace( text_ar[1][1] ); //Traces the text that's entered in instance_1.
This seems like it should be so easy, but I've tried three or four ways to do it (but to no avail).
I'm just trying to put a query result in a viewbag and display it.
I've tried putting a model object list in a ViewBag:
var mesg = from MSG in lemondb.Messages
where MSG.msg == Membership.GetUser().ToString()
select MSG;
ViewBag.messages = MSG;
And then I try to spit it out in a .cshtml:
var message = (List<LemonTrader.Models.Message>)ViewBag.messages; // <--- fails here because it is a string
foreach ( var MSG in message )
{
#Html.Label(MSG.msg)<br />
}
But it says:
Cannot convert type
'System.Data.Entity.Infrastructure.DbQuery'
to
'System.Collections.Generic.List'
So it seems I'm using using the wrong template. How do I spit out a System.Entity.Infrastructure.DbQuery?
I've also tried passing the results through the Viewbag as a list of strings. (Is that a worse way to do it?)
var mesg = from MSG in lemondb.Messages
where MSG.msg == Membership.GetUser().ToString()
select MSG.msg;
ViewBag.messages = mesg;
And spitting it out as a string list:
foreach (var atext in ViewBag.messages as List<string>) { // gets hung up on foreach here (why???)
#Html.Label( atext )
}
And I get this:
Object reference not set to an
instance of an object.
And it points at the "foreach" keyword.
Does that mean there were no messages? Or what?
I wish there was a tutorial showing how to put queryresults in a ViewBag and how to get them out! I've seen tutorials that return an object.ToList() without respect to any kind of "where" mechanism, but no examples to pull out a few, relevant entries and display them.
Try
ViewBag.messages = MSG.ToList();
Also, System.Data.Entity.Infrastructure.DbQuery implements IEnumerable ( http://msdn.microsoft.com/en-us/library/system.data.entity.infrastructure.dbquery(v=vs.103).aspx ) so this should also work:
var message = (IEnumerable<LemonTrader.Models.Message>)ViewBag.messages;
