Is that possible to read data from Database into Config.groovy?

Question

I need to to read data from database to be read into Config.groovy.

Is that possible to get data from Database into Config.groovy?

Answer 1

No it is not possible. In the sequence of events when a Grails application is starting up the Config.groovy is processed before the Datasource is made available to the application.

Without knowing what you are trying to accomplish I can't make a suggestion on how else to approach this issue.

Updated (based on comment)

In your comment you explain that you are trying to use the feature switch plugin (which is designed to be run time and not persistent). Looking at the source code for the plugin you should be able to make your own service that will load the settings from the database and toggles/updates the feature switch settings. Here is just a simple sketch/example:

package example

import org.springframework.beans.factory.InitializingBean

class MyExampleService implements InitializingBean {
  def grailsApplication
  void afterPropertiesSet() {
    // here is where you would do whatever you needed to load the settings
    grailsApplication.config.features['somefeature'].enabled = true
    grailsApplication.config.features['otherfeature'].enabled = false
  }
}

That should at least give you an idea.

Alternatively you could just write it all in Bootstrap.groovy which can access the datasource/GORM as well.
