Question

Multiple callbacks

Hello,

I need to make a button visible based on a few conditions

1. If current user contact record has a lookup value of "Approver"

and

2. If account record of the current user contact has lookup value "Enterprise"

Since there are 2 tables to be queried, I understand I need to use callbacks and chaining. This does not seem to work well for me. I have also tried passing a callback function within a callback function, but still its not working well. Can someone please give an example of multiple callbacks?

Thanks

There's no need for the multiple callbacks since this can be done in a single ESQ query. For example, the ESQ below retrieves both the current user's Type value as well as the current user's account Type value in the same call.

var esq = Ext.create("Terrasoft.EntitySchemaQuery", {
    rootSchemaName: "Contact"
});
 
esq.addColumn("Type");
esq.addColumn("Account.Type", "AccountType");
 
esq.getEntity(Terrasoft.SysValue.CURRENT_USER_CONTACT.value, function (result) {
    if (result.success) {
        var conType = result.entity.values.Type,
            accType = result.entity.values.AccountType;
 
        if ((conType &amp;&amp; conType.displayValue == "Approver")
            &amp;&amp; (accType &amp;&amp; accType.displayValue == "Enterprise")) {
            // do something
        }
    }
}, this);

However, to nest a ESQ in a callback of another ESQ it would look like this:

var esq = Ext.create("Terrasoft.EntitySchemaQuery", {
	rootSchemaName: "Contact"
});
 
esq.addColumn("Type");
esq.addColumn("Account");
 
esq.getEntity(Terrasoft.SysValue.CURRENT_USER_CONTACT.value, function (result) {
    if (result.success) {
        var conType = result.entity.values.Type,
            account = result.entity.values.Account;
        if (conType &amp;&amp; conType.displayValue == "Approver") {
            var esq = Ext.create("Terrasoft.EntitySchemaQuery", {
                rootSchemaName: "Account"
            });
 
            esq.addColumn("Type");
 
            esq.getEntity(account.value, function (result) {
                if (result.success) {
                    var accType = result.entity.values.Type;
                    if (accType &amp;&amp; accType.displayValue == "Enterprise") {
                        // do something
                    }
                }
            }, this);
        }
    }
}, this);
