Help with Apex Trigger for Contacts

Hello -

I have a new trigger in place to prevent users from deleting of contacts from our environment.

Here is a copy of my code:

trigger DeletePrevention on Contact (before delete) {

    for (Contact mo : Trigger.old) {

        mo.addError('Youre Not Allowed to Delete Client Contacts');
    }
}

However, I need to figure out to restrict this to ONLY one RecordType of Contact ('Client').

Any suggestions or help would be greatly appreciated.

Thanks!

Hi Chris,
Please try following code.
trigger DeletePrevention on Contact (before delete) {
    //Retrive Client Record Type Id
    public  Id clientRecordTypeId = Schema.SObjectType.Contact.getRecordTypeInfosByName().get('Client').getRecordTypeId();

    for (Contact mo : Trigger.old) {

        if(mo.recordTypeId != null && (clientRecordTypeId !=null &&  clientRecordTypeId == mo.recordTypeId))
        {
         mo.addError('Youre Not Allowed to Delete Client Contacts');
        } 
    }
}

Please try below code. I hope that will help you. 
trigger DeletePrevention on Contact (before delete) {

	Set<String> setId = new Set<String>();
    for (Contact mo : Trigger.old) {
		setId.add(mo.id);
	}	

	List<Contact> lstContact = [select id,recordType.Name from Contact where id in : setId];
	
    for (Contact mo : lstContact) 
	{
		
		if(mo.recordType.Name =='Client')
		{
			mo.addError('Youre Not Allowed to Delete Client Contacts');
		}	
    }
}

Please let us know if this will help you.

Thanks Vivek and Amit, both work great!

However, I'm running into an issue with my Apex class (test coverage) needed to deploy the trigger to production. 

If possible, can you help?

               Test.startTest();
               try{
               Id clientRecordTypeId = Schema.SObjectType.Contact.getRecordTypeInfosByName().get('Client').getRecordTypeId();
               Account Acct = new Account(Name = 'Test');
