changing standard relationships

[monicaDC]

Hi there!
I need to change the contacts-to-opportunities relationship to one-to-one. How would I go about doing this? Please advise. thank you in advance.

Cheers!
Monica

Hi monica you probably would need to change many fields to do this, isn't it easyer just to add the account's name on the detail view and remove the subpanel?

the standard relationship between opportunities and contact I can find is the one in metadata/opportunities_contactsMetaData.php

I think you can override this in custom changing the relationship_type to "one-to-one"

Something like this:
In custom/Extension/modules/Opportunities/Ext/Vardefs/{name_you_want}.php

$dictionary["Opportunity"]["relationships"]['opportunities_contacts'] = array(
'lhs_module' => 'Opportunities',
'lhs_table' => 'opportunities',
'lhs_key' => 'id',
'rhs_module' => 'Contacts',
'rhs_table' => 'contacts',
'rhs_key' => 'id',
'relationship_type' =>'one-to-one'
);

Perhaps even could work only writing the line of relationship_type like this:
$dictionary["Opportunity"]["relationships"]['opportunities_contacts']['relationship_type'] = 'one-to-one';
