I don't know the details, but this can be accomplished. There is a type of "many-to-many" in your relationship types on the cfproperty tag. Also, there is a linktable attribute that you use. So I'm pretty sure it can handle it, you just have to set it up. Look up many-to-many relationships in the documentation. Don,

Thus I still have to know SQL to work with a database and ORM is rapidly becoming useless to me. After extensive googling I have come to the conclusion that ORM can not handle pivot tables.

Is there a fix for this? Thanks. The release notes are out for CF 9.0.1 and it does not seem to include a fix for passing null values from Flex to a CF ORM object that I mentioned Feb. 19, above.

I have a table with volunteers, a table of organizations, then a pivot table to match up volunteers to organizations. A volunteer can belong to more than 1 organization. I'm thinking I have to make an association from volunteers to pivot and pivot to organizations. Should that work so that when I pull up a volunteer I will see all organizations they belong to and if I pull up an organization I will see all volunteers for that org?

If you have set cascade="save-update" or "all" on the one-to-many relationship, then the EntitySave call on the parent will automatically be cascaded to the child objects. If there is no cascade defined, then you need to call EntitySave on the child objects as well. p.s : In case you are not aware, there is a google group for CF-ORM at http://groups.google.com/group/cf-orm-dev/ which is quite active and you can ask all your ORM related questions there as well.

Or do I have to save each child entity separately ? For example... cust = EntityNew("Customer"); cust.firstname ='Ted'; cust.lastname="Williams'; item1=EntityNew("Item"); item1.name='boots'; item1.setCust(cust); cust.addItem(item1); item2=EntityNew("Item"); item2.name='hat'; item2.setCust(cust); cust.addItem(item2); EntitySave(cust); // Will this persist the cust along with the related items to the database , or do I have to do a seperate entitysave for each item as well ? Hi Rupesh,

Quick question…. if I have the one-to-many mappings done with inverse set on the child object in the parent, shouldn’t I just be able to do an entitysave on the parent object and let ORM take care of saving the children objects ? Or do I have to save each child entity separately ?

For example…

cust = EntityNew(”Customer”);
cust.firstname =’Ted’;
cust.lastname=”Williams’;
item1=EntityNew(”Item”);
item1.name=’boots’;

item1.setCust(cust);
cust.addItem(item1);

item2=EntityNew(”Item”);
item2.name=’hat’;

item2.setCust(cust);
cust.addItem(item2);

EntitySave(cust);
// Will this persist the cust along with the related items to the database , or do I have to do a seperate entitysave for each item as well ?

Couple of options
- EntityLoad(’Artist’, {lastName=”blahblah”});
- ORMExecuteQuery(”from Artist where lastName=?”, [lastName]);

Check the documents for EntityLoad and ORMExecuteQuery.
