Can't assign account to Contact

Question

For a visualforce page, in my constructor i'm assigning a variable and retrieving an account from an associated opportunity - when I do a system.debug I get the details I want:

myObject__c myObject = [SELECT etc... ];
System.debug(myObject.opportunity__r.account);

Output:

Account:{Name=Traffic, BillingStreet=Example 34, BillingCity=Example, BillingCountry=Example, BillingPostalCode=D-80807, Website=www.google.com, Id=003N000000iTbKxXXX, CurrencyIsoCode=USD}

But, when I try to save a contact using a save function, and assign this account, the contact is saved, but it doesn't have any account saved to it.

Contact newContact = new Contact();
newContact.FirstName = contactFirstName;
            newContact.LastName = contactLastName;
            newContact.Title = contactJobTitle;
            newContact.Email = contactEmail;
            newContact.Phone = contactPhone;
            newContact.Account = myObject.opportunity__r.account;
            newContact.event__c = myObject.opportunity__r.expo__r.show__c;

            insert newContact;

Everything else is assigned but there is nothing for account, but when I debug the same variable, it displays the required information. Why is this happening?

Answer 1

Contact's Account accepts an ID field (the correct field to use is AccountId), try the following query:

Contact newContact = new Contact();
newContact.FirstName = contactFirstName;
        newContact.LastName = contactLastName;
        newContact.Title = contactJobTitle;
        newContact.Email = contactEmail;
        newContact.Phone = contactPhone;
        newContact.AccountId = myObject.opportunity__r.account.Id;
        newContact.event__c = myObject.opportunity__r.expo__r.show__c;

        insert newContact;

You were trying to set the entire Account object to the Contact's Account field.

Answer 2

You are giving wrong API name here. Correct API name is AccountID. So change this line

newContact.AccountId = myObject.opportunity__r.accountID;
