So say I am using a form to build a query against my datasource (i've come so far in two weeks! I can do this!), how do I make it more complex?
What if I want books by austen that include the word "pride" AND books by gabaldon that contain the word "Snow"
the individual queries would be
widget.datasource.query.filters['author']._contains = "austen";
widget.datasource.query.filters['title']._contains = "pride";
and
widget.datasource.query.filters['author']._contains = "gabaldon";
widget.datasource.query.filters['title']._contains = "snow";
in pseudosql it would be
select * from table
where
((author like 'austen') and (title like 'snow'))
or
((author like 'gabaldon') and (title like 'pride'))
Is there a way to filter a data source on a complex query like this and cut out the whole widget.datasource aspect? I'd be fine with using a calculated table.
Edit: Ok i'm making some progress towards the kind of functionality I need, can anyone tell me why this works:
widget.datasource.query.filters.document_name._contains = 'x';
but this does not?
widget.datasource.query.parameters.v1 = "x";
widget.datasource.query.where = 'document_name contains :v1';
this also doesn't work:
widget.datasource.query.where = 'document_name contains "x"';

// I have a custom metadata object named boatNames__mdt and I'm using two methods to get a list of picklist values in a String[];
First Method
Map<String, boatNames__mdt> mapEd = boatNames__mdt.getAll();
string boatTypes = (string) mapEd.values()[0].BoatPick__c;
// BoatPick__c is a textarea field (Eg: 'Yacht, Sailboat')
string[] btWRAP = new string[]{};
**btWRAP**.addAll(boatTypes.normalizeSpace().split(','));
Second Method
string[] strL = new string[]{};
Schema.DescribeFieldResult dfr = Schema.SObjectType.boatNames__mdt.fields.BoatTypesPicklist__c;
// BoatTypesPicklist__c is a picklist field (Picklist Values: 'Yacht, Sailboat')
PicklistEntry[] picklistValues = dfr.getPicklistValues();
for (PicklistEntry pick : picklistValues){
**strl**.add((string) pick.getLabel());
}
Map with SOQL query
Map<Id, BoatType__c> boatMap = new Map<Id, BoatType__c>
([Select Id, Name from BoatType__c Where Name in :btWRAP]);
When I run the above Map with SOQL query(btWRAP[]) no records show up.
But when I used it using the strl[] records do show up.
I'm stunned!
Can you please explain why two identical String[] when used in exact SOQL queries behave so different?
You are comparing different things so you get different results. Multiple fails here.
mapEd.values()[0].BoatPick__c - this takes 1st element. At random. Are you sure you have only 1 element in there? You might be getting random results, good luck debugging.
normalizeSpace() and trim() - you trim the string but after splitting you don't trim the components. You don't have Sailboat, you have {space}Sailboat
String s = 'Yacht, Sailboat';
List<String> tokens = s.normalizeSpace().split(',');
System.debug(tokens.size()); // "2"
System.debug(tokens); // "(Yacht, Sailboat)", note the extra space
System.debug(tokens[1].charAt(0)); // "32", space's ASCII number
Try splitting by "comma, optionally followed by space/tab/newline/any other whitespace symbol": s.split(',\\s*'); or call normalize in a loop over the split's results?
pick.getLabel() - in code never compare using picklist labels unless you really know what you're doing. Somebody will translate the org to German, French etc and your code will break. Compare to getValue()
I have the following table in Lua:
local a = {orszag = {"Ausztria", "Albánia", "Azerbajdzsán"}, varos = {"Ankara", "Amszterdam", "Antwerpen"}, fiu = {"Arnold", "Andor", "Albert"}, lany = {"Anna", "Anasztázia", "Amanda"}}
I would like to do the following:
for i in a["orszag"] do etc. (for example compare all the words in the value to the user input)
But when I do so I get the following: attempt to call a table value.
So I know, it works in python for example, but is it possible somehow to do this in Lua as well?
Use
for k,v in pairs(a["orszag"]) do
Im trying to show the total number of people in each geography when they hover over using crossfilter, but my current code is only showing the total of all geographies. So what is the equivalent in crossfilter to the sql query: SELECT COUNT(*) GROUP BY dma
This is my code so far
//geography that is being hovered over, getting dma name and removing everything that is after the comma
sel_geog = layer.feature.properties.dma_1;
sel_geog = sel_geog.split(",")[0];
console.log(sel_geog);
//crossfilter to get total number of people of each geography
var dmaDim = voter_data.dimension(function(d) {return d.dma == sel_geog}),
dma_grp = dmaDim.groupAll().reduceCount().value();
console.log(dma_grp);
Crossfilter isn't meant to be used in a way where you are building new dimensions and groups for each user interaction. It's meant to build dimensions and groups before interactions take place and then update them quickly when filtering based on user interactions.
It's not really clear from this question what your data looks like or what you are trying to do, but you probably want to create dimensions and group for your dma property and then build your map based on that:
var voter_data = crossfilter(my_data);
var dmaDim = voter_data.dimension(function(d) { return d.dma; });
var dmaGroup = dmaDim.group();
At this point dmaGroup.all() will be an array of objects that looks like { key: 'dmaKey', value: 10 } where 10 is the count of all records where d.dma === 'dmaKey'. There are lots of ways you can aggregate differently with Crossfilter, but that may get you started.
Anyone have sample lookup code for AOT objects? (or know where to find the one they use for the AX properties window)
I need to replicate the functionality that you see in several fields in the properties window. The ExtendedDataType field is a good example. Type a few letters, hit the down arrow, and a filtered list of AOT ExtendedDataType objects appears.
I've been trying to use treeNode findChildren to build my custom lookup list, but it is very slow. Whatever method AX is using happens instantly.
Thanks
Try this:
Dictionary d = new Dictionary();
int i;
int cnt = d.tableCnt();
TableId tableId;
str nameForLookup;
for (i = 1; i <= cnt; i++)
{
tableId = d.tablecnt2id(i);
nameForLookup = tableid2name(tableId);
}
Queries to the Model/Util*Element tables will not be cached, and are relatively slow due to the number of records that they contain.
There may be other factors slowing down execution as well. If you are on 2012, for lookups, you may want to build a temp table with an XDS() method, which populates itself using the above code, then you can simply select from that table (and it will be cached for the session):
create a SQL Temp table (e.g. with a name like MyTableLookup), add a name column
add a method like this:
public RefreshFrequency XDS()
{
MyTableLookup tableLookup;
ttsbegin;
// Use the above code to insert records into tableLookup
ttscommit;
return RefreshFrequency::PerSession;
}
bind your form to MyLookupTable
You may develop an estándar EDT linked to the UtilElement Table properly filtered. This will show a list of objects and will have same functionality of all table-linked text fields.
I'm creating a table that displays information from a MySQL database, I'm using foreignkeys all over the place to cross-reference data.
Basically I have a datagrid with a column named 'system.' The system is an int that represents the id of an object in another table. I've used lableFunction to cross-reference the two and rename the column. But now sorting doesn't work, I understand that you have to create a custom sorting function. I have tried cross-referencing the two tables again, but that takes ~30sec to sort 1200 rows. Now I'm just clueless as to what I should try next.
Is there any way to access the columns field label inside the sort function?
public function order(a:Object,b:Object):int
{
var v1:String = a.sys;
var v2:String = b.sys;
if ( v1 < v2 ){
trace(-1);
return -1;
}else if ( v1 > v2 ){
trace(1);
return 1;
}else {
trace(0);
return 0;
}
}
One way to handle this is to go through the objects you received and add the label as a property on each of them based on the cross-referenced id. Then you can specify your label property to display in your data grid column instead of using a label function. That way you would get sorting as you'd expect rather than having to create your own sort function.
The way that DataGrids, and other list based classes work is by using itemRenderers. Renderers are only created for the data that is shown on screen. In most cases there is a lot more data in your dataProvider than what is seen on screen.
Trying to sort your data based on something displayed by the dataGrid will most likely not give you the results you want.
But, there is no reason you can't call the same label function on your data objects in the sortFunction.
One way is to use the itemToLabel function of the dataGrid:
var v1:String = dataGrid.itemToLabel(a);
var v2:String = dataGrid.itemToLabel(b);
A second way is to just call the labelFunction explicitly:
var v1:String = labelFunction(a);
var v2:String = = labelFunction(b);
In my experience I have found sorting to be extremely quick, however you're recordset is slightly larger than what I usually load in memory at a single time.
