I have a following domain class:
class User {
static hasMany = [roles:String]
}
I would like to find every user which has role ROLE_ADMIN
. Is there any possibility to do that with dynamic finders? user.findAllByRoles('ROLE_ADMIN')
seems to give me an error.
UPDATE: it is quite easy to query association where Class A
has a list of class B
instances and both A
and B
are domain classes. But here class A
is a domain class and class B
is a simple Java string.
The code for querying association containing list of another domain objects would look like this:
`User.findAll { roles { role_name=='ROLE_ADMIN' } }`
What i am looking for is a way to specify the value of a String, for example:
`User.findAll { roles {THIS_VALUE=='ROLE_ADMIN' }}`
UPDATE 2: as far as i have found it is not possible to use criteria with collections of primitive types. It is possible to use HQL though:
User.findAll("from User a where :roles in elements(roles)",[roles:'ROLE_ADMIN'])
However it is not as usefull as a findAll
or where
query. I cannot chain findAll
methods so defining other methods that for example: get ROLE_ADMIN
users with username like 'xxx' requires rewriting whole HQL
query. Maybe it is possible to express above HQL
condition in form of a where
expression?
Maybe you can do something like:
if you have already a user list (userList)
def list = userList.findAll { user -> user.roles =~ 'ROLE_ADMIN' }
Hope this help!
I have the same problem How to find records by value in their association property via DetachedCriteria
I made some investigation and, as I found, it's impossible. The GORM DSL itself doesn't have any method to check that value contains in association. It conains oly that criterias that are in SQL: AND
, OR
, IN
.
But! You can join association as table in criteria Querying by Association Redux
