Filtering GORM objects based on attribute grails

Question

I have a filter, for example lets assume the name John Doe is who a user is searching for.

I have the following domain object structure: Company--->Employee--->Name. Where employee is an attribute of company, and name is an attribute of employee. Now, the filter is for the name attribute, but I need to keep a reference to the Company. So for example I did:

companyList.events.each {
if(it.employee!=null){
      if(it.employee.name.toString().toLowerCase().contains(filter)){  
         filterSet.add(it)
      }
}

Unfortunately, this operation is very slow for 1500 entries. However if I do something like,

def searchResults = Company.findAll{
    employee.name == filter
}

It is very fast, but I need the filter to get matched with partial names (i.e. saying Joh would still match John Doe. I know there is an operation called like but I have been unsuccessful using it.

Any help would be really appreciated.

Answer 1

I suggest you look at using criteria. So in this case you could do this:

def filter = 'joh'
def searchResults = Company.createCriteria().list() {
  employee {
    ilike('name', "%${filter}%")
  }
}

Answer 2

Try this:

Company.findAll ("from Company c where c.employee.name like '%'| |:filterName| |'%'", [filterName: yourFilterName])

This query has to be fast.
