### Dynamic Script Integration Points

### Function Dictionary

Sometimes you have a set of values, and for a given value you want to run a certain function. Rather than a big if-then-else clause, consider putting anonymous functions into a dictionary:

```
// String - Func dictionary for values that come from the well record.

var m_wellInitVals = dict[string, object](
    '187197' : w => DateTime.Now.Date, // TODAY
    '190823' : w => w.WellStatusList.LastOrDefault()?.TotalDepth, // TDEPTH
    '190824' : w => w.WellStatusList.LastOrDefault()?.PlugbackDepth, // PBTD
    '695979' : w => w.WellStatusList.LastOrDefault()?.Perforations, // PERFS
    '700013' : w => w.Route?.RouteName, // ROUTE
    '700012' : w => w.Facility?.FacilityName // FACILITY
);
```

```

// String - Func dictionary for values that come from the well svc proxy.

var m_proxyInitVals = dict[string, object](
    '700017' : p => p?.dgm_updated, // DGM_UPDATE_DATE
    '700008' : p => p?.open_perf_status, // PERF_STATUS
    '695979' : p => {
	var top = p?.open_perf_top;
	var bot = p?.open_perf_bottom;
	if top and bot {
	    return string.Format('{0}-{1}', top, bot);
	}
    }, // PERFS
    '707035' : p => p?.open_perf_shots, // PERF_SHOTS
    '695977' : p => p?.gl ? 'GL' : 'KB', // REF_DATUM
    '697919' : p => p?.gl ? p.gl : p?.kb, // REF_ELEV
    '705626' : p => p?.prod_tube_date, // CASING_UPDATE_DATE
    '190827' : p => p?.prod_tube_od, // CASING_OD
    '193184' : p => p?.prod_tube_wt, // CASING_WEIGHT
    '707932' : p => p?.prod_tube_joints, // CASING_JOINTS
    '194068' : p => p?.prod_tube_top, // CASING_TOP
    '194069' : p => p?.prod_tube_bottom, // CASING_BOTTOM
    '702703' : p => p?.tube_tube_date, // TUBING_UPDATE_DATE
    '190667' : p => p?.tube_tube_od, // TUBING_OD
    '702702' : p => p?.tube_tube_wt, // TUBING_WEIGHT
    '194315' : p => p?.tube_tube_grade, // TUBING_GRADE
    '695970' : p => p?.tube_tube_joints, // TUBING_JOINTS
    '707477' : p => p?.tube_tube_top, // TUBING_TOP
    '707478' : p => p?.tube_tube_bottom // TUBING_BOTTOM
);
```

```

// Runs when the field is first added to the form.

def initWellSvcField(form, f) {
    var well = getWell(form);
    var p = getWellSvcProxy(well);
    var val = null;
    each k, func in m_wellInitVals {
	if f.IsField(k) {
	    val = func(well);
	    break;
	}
    }
    if null == val or val == '' {
	each k, func in m_proxyInitVals {
	    if f.IsField(k) {
		val = func(p);
		break;
	    }
        }
    }
    if null != val {
        f.SetValue(val);
    }
}
```
