I'm expanding my commented examples for myself to help this stuff stick. Thanks in advance for all the help :)


So it seems like there's no way to allow a user to create an object using both:

var('partyA' = party('', 0, 'Nokia', '123 Main Street', 'Atlanta', 'GA', '30341', 'active'))

and

var('partyA' = party(-active_status='activeX', -name= 'Nokia', -address='123 Main Street', -city='Atlanta', -state='GA', -zip='30341'))


by having the onCreate methods in my type below; it seems like I can only do 1 way or the other, not both.

Is that correct?



[
// define the CLASS (named "party")
define party => type {


// define Properties (aka local variables)
// data = define variables inside the type
// public = can be used outside the type and can be output on the page
// private = can only be called from methods defined within the owning type; can only be used inside the type and can NOT be output on the page
// protected = can be called from within the owning type or any type that inherits from that type; can NOT be output on the page
// ::string means assigned values must be text strings
// = '' means that if no default value is assigned, use '' (empty string) as the default value

data
protected tablename::string = 'party', // default tablename is party
public name::string = '',
public address::string = '',
public city::string = '',
public state::string = '',
public zip::string = '',
public active_status::string = '',
private id::integer = 0 // default ID is 0


// make status an alias for active_status)
public status() => { return .active_status }


// define METHODS


// _default_ onCreate method, with no data members, is added here to allow you to create the object WITHOUT REQUIRING default values; only need to add this default onCreate method IF any other onCreate methods exist

// means can create object like this:
// var('myParty' = party())
public onCreate() => {}


// define other public onCreate methods ONLY if you want to REQUIRE default values for each of the local variables when the object is created
// .'name' = #name means set the local variable value to the assigned default value if it exists

// add this onCreate method so can create object like this:
// var('partyA' = party('', 0, 'Nokia', '123 Main Street', 'Atlanta', 'GA', '30341', 'active'))

public onCreate(
tablename::string = 'party', // default tablename is PARTY
id::integer = 0, // default ID is 0
name::string = '',
address::string = '',
city::string = '',
state::string = '',
zip::string = '',
active_status::string = '') => {
.'tablename' = #tablename
.'id' = #id
.'name' = #name
.'address' = #address
.'city' = #city
.'state' = #state
.'zip' = #zip
.'active_status' = #active_status // use local variable name 'status' to access active_status
}



// ... = local variable called 'rest'
// this onCreate means can create object like this:
// var('partyA' = party(-active_status='activeX', -name= 'Nokia', -address='123 Main Street', -city='Atlanta', -state='GA', -zip='30341'))

public onCreate(...) => {
with i in #rest do => {
match(#i->name) => {
case('name')
.name = #i->value
case('address')
.address = #i->value
case('city')
.city = #i->value
case('state')
.state = #i->value
case('zip')
.zip = #i->value
case('active_status')
.active_status = #i->value
}
}
}
}
]
