I'm trying to use sObject to dynamically change Name field objects across while organization.
I've tried using SomeId.getSObjectType().newSObject(SomeId) to create the sObject, but when I try to change the Name field I have error
Variable does not exist: Name
Map<Id, string> idsToUpdate = new Map<Id, string>();
// Put the Id's and associated name values in the map
List<SObject> sObjectsToUpdate = new List<SObject>();
foreach(Id idToUpdate : idsToUpdate.keySet) {
SObject o1 = idToUpdate.getSObjectType().newSObject(idToUpdate);
o1.Name = idsToUpdate.get(idToUpdate);
sObjectsToUpdate.add(o1);
}
update sObjectsToUpdate;
As I can see other posts, this is the way of creation dynamic update of objects.
Any idea why this happens?
Not all objects have a name field, you should check for the existence of the name field before trying to set the field also you must use the put method
Map <String, Schema.SObjectField> fieldMap = o1.getSobjectType().getDescribe().fields.getMap();
if(fieldMap.containsKey('Name')){
o1.put('Name', 'Test');
}

I have a requirement to make to make a file private and be available to only the user whose role name consists the name of the file for a specific custom object. For this I am trying to retrieve from Content Document Link with the custom object name LinkedEntity.Type and ContentDocumentid as filters, when I hard code the ContentDocumentid it is working fine but when I try to dynamically provide the ContentDocumentId then the query is not returning any result. I am adding a snippet of my code. Please Help!!. Thanks
List<Id> listOfConDocuId = new List<Id>();
for(ContentVersion cv: Trigger.new){
if((!cv.Title.contains('product proposal')) || (!cv.Title.contains('final')) || (!cv.Title.contains('packet')))
listOfConDocuId.add(cv.ContentDocumentId);
}
Map<Id, Project__c> mapOfProjectId = new Map<Id, Project__c>([SELECT Id FROM Project__c]);
Set<Id> setOfProjectId = mapOfProjectId.keySet();
List<ContentDocumentLink> LinkedProject = [SELECT ContentDocumentId, LinkedEntityId, ContentDocument.Title FROM ContentDocumentLink where LinkedEntityId in :setOfProjectId and LinkedEntity.Type='Project__c' and ContentDocumentId IN :listOfConDocuId];`
I don't think it's necessary to add a WHERE clause for both ID and TYPE. Id should be enough. As far as restricting files to only users with certain roles, have you tried sharing the Custom Object (Project__c) with only those users and then simply linking the files to that Custom Object record with Inferred Permission?

Very new to Apex and never touched java, basically what I am trying to do is delete all records then insert records inside multiple custom objects. Bellow is my code for just the deleting part but I have no idea how to get this working. Once I know how to get it working I can then put it inside a lop etc I just need the basics running first.
List<String> myList = new List<String> {'More_Info_Request__c'};
String foo = myList.get(0);
List<More_Info_Request__c> existing = [SELECT Id From :foo ];
delete existing;
Any help would be amazing
for future me or future human this is how I fixed it:
List<String> objectNames = new List<String> {'More_Info_Request__c', 'Object1__c', 'Object2__c'};
for (String objectName : objectNames) {
List<SObject> existing = Database.query('select id from ' + objectName);
delete existing;
}
in my visualforce page i have some campaign object first user select an object then there is a multi picklist. in this picklist there is Label for all the fields user selects some fields then i have to show the value of these fields in the selected campaign object
for showing multiple picklist my apex function is
public List<SelectOption> getOptionalFields(){
Map <String, Schema.SObjectField> fieldMap= Campaign.sObjectType.getDescribe().fields.getMap();
List<SelectOption> fieldsName =new List<SelectOption>();
for(Schema.SObjectField sfield : fieldMap.Values())
{
schema.describefieldresult dfield = sfield.getDescribe();
fieldsName.add(new SelectOption(dfield.getName(),dfield.getLabel()));
}
but i have no idea how to show value for the the field
for exmple i have object instance like
Campaign c;
now i have to get value of any field whose Name is in string form.how to get corresponding value for that field.one solution is just write like
say
String fieldName;
and use multiple if
if(fieldName=='Name')
c.Name=
if(fieldName=='Id')
c.Id=
is there any other convenient method??please explain!!
You need to read about "dynamic apex". Every "concrete" sObject (like Account, Contact, custom objects) can be cast down to generic sObject (or you can use the methods directly).
Object o = c.get(fieldName);
String returnValue = String.valueOf(o);
There are some useful examples on dynamic get and set methods on Salesforce-dedicated site: https://salesforce.stackexchange.com/questions/8325/retrieving-value-using-dynamic-soql https://salesforce.stackexchange.com/questions/4193/update-a-records-using-generic-fields (second question is a bit more advanced)
You'll still need to somehow decide when to return it as String, when as number, when as date... Just experiment with it and either do some simple mapping or use describe methods to learn the actual field type...
Here my code for apex trigger.
trigger LeadTrigger on Lead (after insert)
{
if(Trigger.isInsert){
for(Lead newLead: Trigger.new)
{
//newLead.RecrodTypeId //'Give value of record type id.
//newLead.RecordType.Name //'Null'
}
}
}
Why "newLead.RecordType.Name" returns null?
The lists of objects available in triggers only have values for the fields on the object the trigger is running on. No relationships are traversed, only the IDs of the lookup records are included.
Therefore, to pull in any extra information you need to from related objects needs to be queried for.
You'll want to do something like this:
trigger LeadTrigger on Lead (after insert) {
map<id, RecordType> mapRecordTypes = new map<id, RecordType>();
if(Trigger.isInsert) {
for(Lead newLead: Trigger.new) {
mapRecordTypes.put(newLead.RecordTypeId, null);
}
}
for(RecordType rt : [select Id, Name from RecordType
where Id in : mapRecordTypes.ketSet()]) {
mapRecordTypes.put(rt.Id, rt);
}
for(Lead newLead : Trigger.new) {
string recordTypeName = mapRecordTypes.get(sLead.RecordTypeId).Name;
}
}
This is probably because some of your leads that just got inserted don't have record types associated with them. This is normal. You can enforce that record type selection is mandatory through configuration, if that's what you're looking for.
[EDIT]
Now I think I understand the issue (from your comment). The reason is that since you're in a trigger, the associated RecordType referenced object is not available. The RecordTypeId will always be available since it is literally part of the trigger object as an Id. However, child objects (referenced objects) will not be available to simply reference from within a trigger. To do this you need to create a map of the referenced object in question by doing an additional SOQL call WHERE Id IN: theIdList.
From Apex, not in a trigger, you need to specifically call this field out from your SOQL like this:
List<Lead> leads = [SELECT Id, RecordType.Name FROM Lead];
What just happened there is that the child object, the RecordType in this case, was included in the query and therefore available to you. By default a trigger will not have all of your child objects pre-selected and therefore need to be selected afterwards from within the trigger or class called by the trigger:
List<Id> recIds = new List<Id>();
for(Lead l : leads)
{
recIds.add(l.RecordTypeId);
}
List<RecordType> rt = [SELECT Id, Name FROM RecordType WHERE Id IN :recIds];
Map <Id, String> idRecNameMap = new Map<Id, String>();
for(RecordType r : rt)
{
idRecNameMap.put(r.Id, r.Name);
}
// And finally...
for(Lead l : Trigger.new)
{
String tmpRecordTypeName = idRecNameMap.get(l.RecordTypeId);
}
I did not test this code but I think it look ok. Hope this makes sense.
you can't get extra information on the related objects from this trigger. if you want to get more information you need to make query for other objects.
List<RecordType> records = [SELECT Id, Name FROM RecordType WHERE Id = newLead.RecrodTypeId];
string myname = records[0].name;
but remember that you shouldn't make a query in for loop. so if you wanted to do it in the right way go for Adam's solution.
Put some system debug inside the loop and check your system debug logs for more information
system.debug('lead:' + newLead);
inside the for loop and see what is being passed in. You may find that it is null.
We cant really give you a good answer without knowint the rest of your set up.
I'm currently using a Gwt CellTable, bound to my GAE/Objectify backend via RPC calls.
All right now! :-)
Then I want to sort columns, so I read http://code.google.com/intl/it-IT/webtoolkit/doc/latest/DevGuideUiCellTable.html#columnSorting
The Async Remote sorting sections shows very well how to get sorting into my AsyncDataProvider but... how can I retrieve the name of the column the user wants to sort?
It shows this code: ColumnSortList sortList = table.getColumnSortList();
But how can I get String names from that? I simply want to know "surname" or "soldDate", the name of the field the column is bound to! Then I will pass it to my rpc service, and use it to sort data server-side query(...).order(<field_name>)
Am I missing something?
UPD: interesting stuff here: http://groups.google.com/group/google-web-toolkit/browse_thread/thread/77a0eaf8086218a6/effb8d3abe69270b#effb8d3abe69270b
You can keep a list of column names ordered as they are in the table:
List<String> columnNames = new ArrayList<String>();
table.addColumn(surnameColumn, "surname");
columnNames.add("surname");
// add the other columns
Then when you need to get the sort column name:
String sortColumnName;
ColumnSortList sortList = table.getColumnSortList();
if (sortList != null && sortList.size() != 0){
Column <MyEntity, ?> sortColumn = (Column <MyEntity, ?>)
sortList.get(0).getColumn();
Integer columnIndex = table.getColumnIndex(sortColumn);
sortColumnName = columnNames.get(columnIndex);
}
// do your rpc call
*where MyEntity is your data object displayed in the cell table.
A bit late to the party, but here's a more straight-forward solution based off of the current documentation (see section 'ColumnSorting with AsyncDataProvider').
When we're adding our columns we can simply set the dataStoreName:
TextColumn<MyData> surname = new TextColumn<MyData>() {
...
}
surname.setSortable(true);
surname.setDataStoreName("surname"); // Set the column name
table.getColumnSortList().push(surname);
table.addColumn(surname, "Last Name"); // eg. A different name for the UI
Then we can retrieve the column's dataStoreName later when sorting:
#Override
protected void onRangedChanged(HasData<MyData> display) {
...
ColumnSortList.ColumnSortInfo info = table.getColumnSortList().get(0);
String sortColumn = info.getColumn().getDataStoreName(); // Get the column name
boolean sortIsAscending = info.isAscending();
rpcService.requestMyData(
sortColumn,
sortIsAscending,
new AsyncCallback<ArrayList<MyData>>() {...}
);
...
}
Using this method we can pass the column name directly to our RPC method. It even allows us to use a different name (eg. the database column name) than the column name used on the UI/client side.
I have used something like this as an application column object.
public class ScrollTableColumn
{
// --------------------------------------------------------------- Field(s)
private int sequence;
private Column column;
private Header header;
private int size;
private int calculatedSize;
private boolean show;
private PartialColumn partialColumn;
private ColumnNameEnum columnName;
}
Now create a HashMap of the above as follows:
Map<Column, ScrollTableColumn> columnMap
= new HashMap<Column, ScrollTableColumn>();
Add all the columns as you create them both in the ScrollTableColumn and in the columnMap.
Finally you can get the required name as:
ColumnSortList sortList = dataTable.getColumnSortList();
Column<?, ?> column = sortList.get(0).getColumn();
ColumnNameEnum = columnMap.get(column);
String name = ColumnNameEnum.getName();
The proper way is to extend the base column class which will allow you to override cell rendering, pass in column configuration via your constructor, and most importantly set the DataStoreName which is where you should store the field name for the column. Lastly you should not reuse the onrangechanged fire, but access the columnsort handler directly by overriding it. on range change and column sort handler should call some type of method that you have to update your grid. I call mine updateGrid for sanity. This allows you to set any grid parameters used by your async request to specific sort column and direction. The main reason you want to use column sort handler is to access the ColumnSort event which contains your sort direction information
your column class that extends the base GWT column. You can also extend date or number columns too.
public GridStringColumn(String fieldName, String text, String tooltip, boolean defaultShown, boolean sortable, boolean hidden) {
super(new TextCell());
setDataStoreName(fieldName);
this.text_ = text;
this.tooltip_ = tooltip;
this.defaultShown_ = defaultShown;
setSortable(sortable);
this.hidden_ = hidden;
}
create your handler
dataGrid.addColumnSortHandler(new DataGridSortEvent());
your sort event class
protected class DataGridSortEvent implements ColumnSortEvent.Handler {
#Override
public void onColumnSort(ColumnSortEvent event) {
ColumnSortList sortList = dataGrid_.getColumnSortList();
if (sortList != null && sortList.size() > 0) {
Column<T, ?> sortColumn = (Column<T, ?>) sortList.get(0).getColumn();
LOG.info("col_sorta: " + event.isSortAscending());
LOG.info("col_index: " + sortColumn.getDataStoreName());
updateDataList();
}
}
}
updateDataList is your method you use to make the actual AJAX request to your server side. rather then logging you sould store this info in private members of your datagrid class so that your request can parameterize them.
you could also make this work for local caching too, just make a copy of the data from your server locally then return a sorted collection of that cached collection, rather then calling the updateDataList method.
Now you do not need to store a separate list for just string names, which is waste of memory not to mention a synchronicity issue if the column order is change from user interaction or whatever.
