I am trying to implement copy / paste functionality on my folders in jstree.
The problem is that, in the paste event when i access the parent id, it gives me the id of the old parent node of the folder.
I need the new parent_id of the node where the folder is pasted to.
When i implement a cut event followed by a paste event, I am able to get the new parent_id by retrieving it in the paste event, but unfortunately I am not able to get the same for copy/paste .
How can I get new parent_id ?
Please let me know. Thank you. I appreciate your help!
The log statements in the code is as follows:
.on('copy_node.jstree', function (e, data) {
console.log(" copy event ");
console.log(" type : "+data.node.type);
console.log(" id : "+data.node.id);
console.log(" text : "+data.node.text);
console.log(" new parent id : "+data.node.parent)
}).on('paste.jstree', function (e, data) {
console.log(" paste event ");
console.log(" parent id : "+data.node[0].parent);
console.log(" parents id : "+data.node[0].parents);
console.log(" tree node id : "+data.node[0].id);
console.log(" type : "+data.node[0].type);
})
The output seen is as follows:
copy event
type : default
id : j1_5
text : New node
new parent id : j1_2
paste event
parent id : j1_1
parents id : j1_1,#
tree node id : j1_4
type : default
Please NOTE: I am getting new parent_id in the copy event i.e 'j1_2' but I am unable to get it in the paste event. I want this new parent_id in order to persist in the db. The paste event shows parent_id as 'j1_1' which is the old parent_id of the copied node.
In paste event you can find id of the old parent here: data.node[0].original.parent (I assume you are pasting one node, hence node[0]).

data.parent gives me the new parent node id.

So i have written a trigger to prevent user from entering more than one opportunity product to the same opportunity, but the problem is when he adds more than one opportunity product at the same time, my trigger does not fire, salesforce takes it as one product.
What can i add to my trigger to fix this ?
My trigger :
trigger OpportunityLineItemBeforeInsert on OpportunityLineItem (before insert) {
Set<Id>opportunityIds = new Set<Id>();
// get all parent IDs
for(OpportunityLineItem i : trigger.new)
{
opportunityIds.add(i.OpportunityId);
}
// query for related Olis (Opportunity Line Items)
Map<Id, Opportunity> opps = new Map<Id, Opportunity>([SELECT ID,
(SELECT ID
FROM OpportunityLineItems)
FROM Opportunity
WHERE ID IN :opportunityIds]);
for(OpportunityLineItem i : trigger.new)
{
if(opps.get(i.OpportunityId).OpportunityLineItems.size()>0)
{
i.addError('Your Message');
}
}
}
Thank you in advance.
I would probably ignore anything related to the Oppty.
You want only one product created, so on creation, either the number of LI is 0 and you can create exactly one, or it' snot 0 and you can't create any.
I would just create a rollup field on the Oppty, count the products. If the count != 0, then fail the validation. If count = 0, then count the Olis in trigger.new and if !=1, fail.
Instead of writing code to do this you should instead create a field on products that stores the id of the parent opportunity, make that field unique, and populate the value via workflow or process builder with the id of the parent opportunity. That way if a second product gets added the unique constraint would fire and prevent the record from being inserted.
Another option would be to create a rollup on opportunity to count the number of opportunity products, then add a validation rule that show an error if the number of products > 1. The advantage of doing it this way is that you get to set the error message as opposed to the generic duplicate error message with the first option.
I am trying to create a trigger in APEX, when an custom textfield of an custom sObject gets updated with products (means, when new products get insert or existing one get deleted).
How can I compare in APEX the Trigger.Old values with the Trigger? New values of this field in order to start the Trigger.
It would look something like this:
Trigger NameOfTrigger on CustomSObject__c (after update){
/*there is already an existing list of products that get insert into the custom textfield (probably as Strings)
*/
List <String> textList = new List <String> ();
/*PseudoCode: if the textfield got updated/has changed, copy from every entry of this textfield (entry = product name as a string) and copy fieldX into another sObject
*/
if(CustomSObject.field(OldValues) != CustomSObject.field(NewValues)){
for (String product : textList){
//Trigger e.g. copy the values of a certain field of p and paste them in another sObject
}
Could somebody help me with the syntax?
You can utilize inbuilt Trigger.new and Trigger.old to get the latest and old values of any record. These lists can be used to achieve what you're looking for.
Sample example would be:
Trigger NameOfTrigger on CustomSObject__c (after update){
for(CustomSObject__c customObject : Trigger.new) {
// get old record
CustomSObject__c oldCustomObject = Trigger.oldMap.get(customObject.Id);
// compare old and new values of a particular field
if(customObject.fieldName != oldCustomObject.fieldName){
//Trigger e.g. copy the values of a certain field of p and paste them in another sObject
}
}
}
See documentation of Trigger.new & Trigger.old
i want to create Customer diary on the base of customerID that present in customer table.
In customerID field i want dropdown list having list of CustomerId's that are present in database
How can i do that ? can someone help me please
var _objAllCustomerIds = null;
using (AdventureWorksEntities context = new AdventureWorksEntities())
{
_objAllCustomerIds = context.MyCustomers.Select(customer => customer.Id).ToList();
}
//where AdventureWorksEntities is your DBcontent containing all your entities
//MyCustomers is the entities representation of your customer table
if this is in your .aspx file
then in your .aspx.cs file (assuming you're using code behind) you'd get the list of customer IDs and then bind that list to this dropdown.
Does this answer from another question help?
How to bind the selected value of a DropDownList
Need some advise on how to populate a lookup field (contact) via apex trigger
I've created a lookup field called Contact__c on Idea object.
I would like to populate the Contact__c with the createdby User if it was originated from the web (CreatedBy.Contact.Account.Name == "Web Ideas") and leave it empty for internal idea creation.
I have read up and created the following trigger and was able to save and run. However, upon saving the idea record, i am getting an error : UpdateContactonComplaints: data changed by trigger for field Contact: id value of incorrect type: 005N0000000l9iMIAQ
trigger UpdateContactonComplaints on Idea (before insert, before Update) {
list<id> oid = new list<id>();
for(Idea o: trigger.new){
oid.add(o.id);
}
map<id, Idea> ExtendU = new map<id, Idea>(
[select CreatedbyID from Idea where id in: oid]);
for(Idea o: trigger.new){
o.Contact__c = ExtendU.get(o.id).CreatedbyID;
}
}
In the Trigger, the user id(id of the User who created the idea) is assigned to Contact custom lookup field).
So, it throws an error, data changed by trigger for field Contact: id value of incorrect type:
I created a custom object XtendedUser which has an id and Name.
I created a custom lookupfield on Opportunity called "XtendedUser__c" which links the opportunity to the corresponding XtendedUser record.
Now I made it so that the name of an opportunityowner corresponds to the name of an XtendedUser-record, so I want the trigger to autopopulate the custom lookup field "XtendedUser__c" on the opportunity with the id of the corresponding XtendedUser-record of which the name matches the name of the opportunityowner.
I never wrote a trigger, always worked with workflows and fieldupdates, but I've got to make this work. So if you could please help me with this? I would be extremely greatfull!
Thanks in advance
You should use a map to link the records and retrieve the value before the insert of a new record and before the update of an existing record. This technique will also allow you to bulk update all your records. It should be something like:
trigger ExtendedUser__c on Opportunity (before insert, before Update) {
list<id> oid = new list<id>();
for(opportunity o: trigger.new){
oid.add(o.id);
}
map<id, ExtendedUser__c> ExtendU = new map<id, ExtendedUser__c>(
[select name from ExtendedUser__c where id in: oid]);
for(opportunity o: trigger.new){
o.name = ExtendU.get(o.id).name;
}
}
