Display concat fields in relationship

[lenah]

Greetings,

First of all, I want to say that Xataface is awesome! It's very flexible and provides so many options for customization. Bravo!

Now the question: I have a many-to-many relationships between two tables (person and assignment) and an associative table to store the relationship (person_assignment). Here is the simified table structure:
person(pid, firstname, lastname)
assignment(aid, description)
person_assignment(pid,aid)

I defined the relationship in my assignment folder using SQL and the relationship tab works fine.

In the details>edit tab, I use checkbox to allow users to assign the current assignment to multiple people. Currently, the field value for the checkbox is the person's first name. Is it possible to have a concat field value, such as concat(lname, " ", fname)?

Thanks!

Lena

If you implement the getTitle() method on the target table of the relationship to display both names, that should do the job:

Code: Select all

function getTitle(&$record){
    return $record->val('fname').' '.$record->val('lname');
}

Hello Steve,

Thanks for your prompt reply. I have tried your solution. The field names are concatenated in the person tab but the checkboxs in assignment tab still display only the first name

This is how I declared my personname field in fields.ini in assignment folder:
[personname]
widget:type=checkbox
transient=1
relationship=personassignment

I declared personassignment in my relationships.ini:
[personassignment]
__sql__ = "SELECT * FROM person_assignment pa JOIN person p ON pa.pid = p.pid WHERE pa.aid = '$aid'"

I tried implemeting a delegate class on my assignment tab
<?php
class tables_assignment {
function personname__display(&$record){
return $record->val('firstname').' '.$record->val('lastname');
}
}
?>
But it still doesn't work

So your relationship goes from the assignment table to the people table (i.e. it is showing the people that are related to a certain assignment).

Your getTitle() method should be defined in the people delegate class.

This is my person.php
<?php
class tables_person {
function getTitle(&$record){
return $record->val('firstname').' '.$record->val('lastname');
}
}
?>

The title of the record does change to include both last name and first name but the field display of the check box does not

OK.. it is possible that this is a case where you need to use the titleColumn() method instead.

The titleColumn has the same effect as getTitle() (it customizes the columns you mean to use as the title for a record). The difference is that titleColumn() is used when obtaining the title on an entire set of records without having to load the whole record into memory. It uses a different syntax also as it is meant to assist in SQL queries.

e.g.

Code: Select all

function titleColumn(){
    return "concat(firstname,' ',lastname)";
}


It should return a string that can be used as a column identifier in the select clause of an SQL query.

(This method goes in your people delegate class).
