I want to check a list contains a specific string .

before checking all entries in list as well as sting should be in. lowercase

I tried like this

 def venueName = params.name

 def venueNameLists = Venue.executeQuery("select name from Venue")

  if(venueNameLists.toLowerCase().contains(venueName.toLowerCase())){

            error = true;

            log.debug("save :: duplicate name")

            flash.message = "Venue name already exist";

            render(view: "create", model: [venueInstance: new Venue(params)])

            return

        }

gives error

  No signature of method: java.util.ArrayList.toLowerCase() is applicable for argument types: () values: . Stacktrace follows:



  groovy.lang.MissingMethodException: No signature of method: java.util.ArrayList.toLowerCase() is applicable for argument types: () values: 

I agree with aiolos: use constraints or try to find instance by name ignore case. But to fix this your way try *.(star-dot) operator:

venueNameLists*.toLowerCase().contains(venueName.toLowerCase()) 

If you would like to check a duplicate entry before saving an element, use constraints on your domain class. Here you could use unique constraint or implement your own if you need it case insensitive.

If you need to check it manually, try this:

def venueWithNameFromParams = Venue.findByNameIlike(params.name) // ignore case

if(venueWithNameFromParams){

    // venueName is in venueNameList

} 

If you were looking how to check if multiple strings contains a word, while ignoring case-sensitive, use (?i) on a regex of words.

For example, the following will be positive condition:

word = "YES"

word.matches(/(?i)yes|ok|true/)
