specify column name

[andresgr]

Hi.

I'm trying to map legacy database.

One of the tables has a column named "rteFinal".

If i create a domain class with a property called "rteFinal" grails
(0.4 recent download) translates it to "rte_final".

Can i specify column name (something like withColumn="rteFinal")
without creating all hibernate mapping by hand?

Thanks.

If I'm not mistaken this is not supported at the moment, but definitely
would be nice to have "custom" mapping options be available in domain
classes kind of like the association mappings e.g. "hasMany",
"belongsTo", so there would be no need to write custom hibernate mapping
XML.

I don't remember from the top of my head: how does ActiveRecord do it?

Just thinking out loud. How about something like this:

class Person {

    String firstName
    String lastName
   
    def static table = 'person_tbl'
   
    def static columnMappings [firstName:first_nm, last_name:last_nm]
   
}

You can specify table name already with:

static withTable = "xxx"

so maybe what we need is aslo something like

static withColumnNames [...]

Ah OK.

+1 for "withColumnNames" map.

Also how about "withSequence" for sequence id generation strategy?

Hello all,

I be study grails code,  in
GrailsDomainConfiguration.secondPassCompile()  method use  
GrailsDomainBinder.bindClass(domainClass, super.createMappings());.

Why GrailsDomainBinder is global class?? i can't change it to use uuid
strategy id.

I think GrailsDomainConfiguration receive GrailsDomainBinder in the
contructor, in this way i can change it.

Or its is possible in another way???

obs: sorry my english.

Agnaldo

The implementation of GrailsDomainBinder is similar to those within
Hibernate core. They are not designed to be extended. If you want the
ability to generate a uuid mapping then there would have to be a
proposal about how that would look in GORM and then we coulld go from
there

Cheers
