Haneef S Post an attachment on a chatter group automatically using Trigger
Hello All,
I have a requirement to write a trigger and also I am new to salesforce.
Can anyone pls help me
Requirement is:
I have custom object say test__c which is also having notes and attachments related list on it.
when a field called "state__c" is updated to "complete" on test__c object then an attachment(in notes & attchments section) starting with "abc-xxxx" needs to be posted automatically in a group called "my chatter".
My code is:
trigger AttachmentTriggger on Attachment (after insert) {
Map<Id,Id> testAttachmentMap = new Map<Id,Id>();
set<Id> testIds = new set<Id>();
for(Attachment att : Trigger.New)
{
if(att.ParentId.getSobjectType() == test__c.SobjectType){
accountAttachmentMap.put(att.ParentId,att.Id);
}
}
//fetching the account to check the condition
List<test__c> testList = new List<test__c>();
testList =[select id,state from test__c where Id IN : testAttachmentMap.keySet()];
//checking if account is meting the required condition
for(test__c testatt : testList){
if(testatt.state='completed'){
testIds.add(testatt.Id);
}
//add code here to post attachments in group
}
Any help much appreciated.
Thanks

In your case you need to write code on test__c object instead of Attachment.
Please try below code and take care any syntax, object error if any as i do not know exact object and field name of your instance.
-----------------------------------------
trigger AttachFileToTestObjectFeed on test__c (after update) {
List<String> testIdList = new List<String>();
for (test__c newTest : Trigger.New) {
// only completed one
if(newTest!=null && newTest.state__c='complete'){
testIdList.add(newTest.Id);
}
}
// query all attachment for test__c.status='complete'
List<Attachment> attachmentList = [Select Id,ParentId,Body,Name from Attachment where ParentId=:testIdList];
list<FeedItem> listOfFeedFiles = new List<FeedItem>();
if(Trigger.isAfter){
for(Attachment attachment : attachmentList){
//Adding a Content post
FeedItem post = new FeedItem();
post.ParentId = attachment.ParentId; //eg. test__c id
post.Body = 'Attachment added';
post.Type = 'ContentPost';
post.ContentData = attachment.body;
post.ContentFileName = attachment.Name;
post.Title = attachment.Name;
listOfFeedFiles.add(post);
}
}
if(listOfFeedFiles!=null){
insert listOfFeedFiles;
}
}

Please let me know if it works for you.

Please see My code:
trigger accounttrigger on account (after update) {
List<String> accountlist = new List<String>();
for (account newTest : Trigger.New) {
// only completed one
if(newTest!=null && newTest.state__c='completed'){
{
accountlist.add(newTest.Id);
}
}
// query all attachment for account.status=completed
List<Attachment> attachmentList = [Select Id,ParentId,Body,Name from Attachment where ParentId=:accountlist];
list<FeedItem> listOfFeedFiles = new List<FeedItem>();
if(Trigger.isAfter){
for(Attachment attachment : attachmentList){
//Adding a Content post
FeedItem post = new FeedItem();
post.ParentId = attachment.ParentId; //eg. account id
post.Body = 'Attachment added';
post.Type = 'ContentPost';
post.ContentData = attachment.body;
post.ContentFileName = attachment.Name;
post.Title = attachment.Name;
listOfFeedFiles.add(post);
}
}
if(listOfFeedFiles!=null){
insert listOfFeedFiles;
}
}
}
Please see the error below:
I am facing this error .
Thanks in advance
if(newTest!=null && newTest.state__c=='completed'){
Second and third is problem. To make work reduce your class api to 34.0.
Thank you so much.. this is working for me.. Marking this as best answer.
Thanks,
