Re: Pulling in another table in a find query

Hi there,

No, properties do not have an associated area ID. Properties are located via their location_id.

Area ID's are used in another portion of the site but in this case it is necessary to do a search on area's instead of locations.

Lemme give the full picture to explain it more...

Properties are located by a location ID pointing to a location table which has the geomeotric points store in it. Those are single addresses of each property.

Now agencies can request "channels" where they can purchase different suburbs. Those suburbs are stored in the areas table and assigned to each channel via a join areas_channels.

What I need to accomplish now is I need to be able to search for all properties that belong to an agencies channel that are in the channel's areas they have purchased. Hence the area not being directly related to the properties.

I can't assign an area_id to a property as the area has nothing to do with the property.

I'm thinking I may need to do some custom sql magic here....

inside a certain area id.

Property belongsTo Area. That is, the properties table should have an
area_id column.
