Grails external config file path - grails

I'am about to set up a external config file. So I'm using the grails plugin
compile "org.grails.plugins:external-config:1.1.1"
I create the application.groovy that looks like this
grails.config.locations = [
"/Users/username/application.properties"
]
And my application.config file is exactly in this place. By creating a normal file i have access to it and can read out of it.
In my file i have three key value pairs like
firstkey=first
secondkey=second
thirdkey=third
Still this keys does not get added to my config file.
In the class which is placed in the src directory i am able to call the config like this
Holders.config
//No result on calling one of the keys
Holders.config.thirdkey
Has anyone an idea what I have to do additional

grails.config.locations takes spring resource patterns
Try
grails.config.locations = [
"file:///Users/username/application.properties"
]
If the file is in the home directory of the user under which the app is running. You can even use
grails.config.locations = [
"~/application.properties"
]
The examples are already there in docs here
You can enable debug log level for logger grails.plugin.externalconfig. And it will log messages if any of your configured external config file is not found.
logger("grails.plugin.externalconfig", DEBUG, ["STDOUT"])

grails 2.5 does not read properties from home dir when added to grails.config.locations

At the top of config.groovy is this line (now uncommented):
grails.config.locations = [ "file:${userHome}/.grails/${appName}-config.properties"]
So we created a properties file on windows in our home dir /.grails, which contains these lines for the database migration plugin:
contents of c:\Users\me\.grails\myapp-config.properties:
grails.plugin.databasemigration.updateOnStartContexts=XXX
grails.plugin.databasemigration.updateOnStart=true
we restart the app, it completely ignores these values.
If however, we change to a groovy file thusly:
grails.config.locations = [ "file:${userHome}/.grails/${appName}-config.groovy"]
And create the following file: c:\Users\me.grails\myapp-config.groovy
grails.plugin.databasemigration.updateOnStartContexts = 'XXX'
grails.plugin.databasemigration.updateOnStart = true
It works perfectly. It seems it is not possible to use property files with the database migration plugin at least.
However, we need to be able to change these values on production (tomcat + war), which we assume cannot compile groovy files, so wont work.
Luckily, the below part does actually work:
if (System.properties["${appName}.config.location"]) {
grails.config.locations << "file:" + System.properties["${appName}.config.location"]
}
But we would really like to get the home dir version working, so we dont have to worry about system properties and command line arguments in our dev environments.
Any ideas?
change the path separator for windows from / to \
try to put the complete path in locations to check the file can be read

Grails configuration ConfigSlurper

I want to separate config files into few small parts. In Config.groovy I have defined grails.config.locations array to point these files:
grails.config.locations = [
"classpath:config.properties",
"classpath:some-config.groovy",
]
And then I am checking configuration map by accessing: grailsApplication.config
The first configuration file is Java properties file, which loads properly:
config.properties
grails.serverURL=http://localhost:8080/selly
..
The second one is .groovy file which in reference to the documentation (http://grails.org/doc/latest/guide/conf.html#configExternalized) should be loaded from automatically parsed ConfigSlurper file format:
some-config.groovy:
app {
testvar {
foo = true
}
}
But grailsApplication.config.app does not exists (no field in debug and println returns empty map [:]).
Can anyone give an example of loading groovy files?
Files are placed in: grails-app\conf\, for example grails-app\conf\config.properties
It looks like you've configured both files correctly. grailsApplication.config.app might be null simply because it is not a leaf node, have you tried grailsApplication.config.app.testvar.foo?

Can I split config.groovy file of grails?

As there is sensitive code in the config.groovy file, I am afraid that my friends will commit with bugs in this file. When getting svn update, we too will get the buggy config code.
Can i split the code at config.groovy in such a way that the sensitive code remains untouched and the other can be changed frequently?
Inside your main config file you are able to access this variable:
grails.config.locations
It is a list of configuration file locations to which you can add your own files:
grails.config.locations << 'file:MyConfigFile.groovy'
These files will then be added to your configuration.
For a more elaborate setup see this blog post:
http://www.pasopas.nl/2012/loading-grails-configuration-files-update/
Similar to Marijn's answer. This is how I usually set up my Config.groovy. I still use it for some settings, but anything environmentally (deployment location or individual machine) changing can override any settings in the Config.groovy.
Config.groovy >>>>
grails.config.locations = [
"file:../app-config/myapp-dataSource.groovy",
"file:../app-config/myapp-config.groovy"
]
environments {
development {
grails.config.locations = [
"file:../myapp-config/myapp-dataSource.groovy",
"file:../myapp-config/myapp-config.groovy",
"file:${userHome}/myapp-config/myapp-dataSource.groovy",
"file:${userHome}/myapp-config/myapp-config.groovy"
]
some.config.setting=true
}
}
file:${userHome}/myapp-config/myapp-config.groovy >>>>
some.config.setting=false

How do I derive physical path of a relative directory inside Config.groovy?

I am trying to set up Weceem using the source from GitHub. It requires a physical path definition for the uploads directory, and for a directory for appears to be used for writing searchable indexes. The default setting for uploads is:
weceem.upload.dir = 'file:/var/www/weceem.org/uploads/'
I would like to define those using relative paths like WEB-INF/resources/uploads. I tried a methodology I have used previously for accessing directories with relative path like this:
File uploadDirectory = ApplicationHolder.application.parentContext.getResource("WEB-INF/resources/uploads").file
def absoluteUploadDirectory = uploadDirectory.absolutePath
weceem.upload.dir = 'file:'+absoluteUploadDirectory
However, 'parentContext' under ApplicationHolder.application is NULL. Can anyone offer a solution to this that would allow me to use relative paths?
look at your Config.groovy you should have (maybe it is commented)
// locations to search for config files that get merged into the main config
// config files can either be Java properties files or ConfigSlurper scripts
// "classpath:${appName}-config.properties", "classpath:${appName}-config.groovy",
grails.config.locations = [
"file:${userHome}/.grails/${appName}-config.properties",
"file:${userHome}/.grails/${appName}-config.groovy"
]
Create Conig file in deployment server
"${userHome}/.grails/${appName}-config.properties"
And define your prop (even not relative path) in that config file.
To add to Aram Arabyan's response, which is correct, but lacks an explanation:
Grails apps don't have a "local" directory, like a PHP app would have. They should be (for production) deployed in a servlet container. The location of that content is should not be considered writable, as it can get wiped out on the next deployment.
In short: think of your deployed application as a compiled binary.
Instead, choose a specific location somewhere on your server for the uploads to live, preferably outside the web server's path, so they can't be accessed directly. That's why Weceem defaults to a custom folder under /var/www/weceem.org/.
If you configure a path using the externalized configuration technique, you can then have a path specific to the server, and include a different path on your development machine.
In both cases, however, you should use absolute paths, or at least paths relative to known directories.
i.e.
String base = System.properties['base.dir']
println "config: ${base}/web-app/config/HookConfig.grooy"
String str = new File("${base}/web-app/config/HookConfig.groovy").text
return new ConfigSlurper().parse(str)
or
def grailsApplication
private getConfig() {
String str = grailsApplication.parentContext.getResource("config/HookConfig.groovy").file.text
return new ConfigSlurper().parse(str)
}

Using External Configuration File

I've added the code below to my Config.groovy file, however, in spite of having it I'm not able to access the external configuration properties in the Config.groovy file.
Does anyone how I can access the properties of the external configuration file within the Config.groovy file?
if (System.getProperty("CONFIG")) {
grails.config.locations << "file:" + System.getProperty("CONFIG")
} else {
grails.config.locations << "file:./${appName}-config.properties"
}
Note: I've tried using ${...} like I would in Spring configuration files, ConfigurationHolder.config, and grailsApplication to access the properties but none of these approaches work.
Thanks.
I think this would cause confusion due to the order the config files are loaded. I'm pretty sure at the time the Config.groovy is loaded, the external one hasn't been loaded yet.
So your "CONFIG" property is set in the external file, which is the name of the file that you want to load?
How I usually do this is just list all the files that I could use.
grails.config.locations = [
"file:../app-config/myapp-dataSource.groovy",
"file:../app-config/myapp-config.groovy"
]
environments {
development {
grails.config.locations = [
"file:../myapp-config/myapp-dataSource.groovy",
"file:../myapp-config/myapp-config.groovy",
"file:${userHome}/myapp-config/myapp-dataSource.groovy",
"file:${userHome}/myapp-config/myapp-config.groovy"
]
}
...
}
If the files do not exist they are just skipped. Files I believe are loaded in order, so anything in the ${userHome} dir, will override the previously set values. This is nice for development, as you can have machine local ways of changing settings, and not have to worry about these config changes being checked in.
#Nick Larson,
What you mentioned about CONFIG not loaded is not true. If CONFIG is a JVM parameter, set with -DCONFIG=xxxx, then it is set before config.groovy kicks in.
#Kin1,
You are using file: protocol for accessing the property file. Are you trying to access this in a WAR or EAR file or is it a file based system.
In a WAR or EAR file you need to use classpath: for the file, file: does not work. Also, you have to make sure to actually copy the Groovy file(not compiled class file) in the classpath. We do it on WAR create event and the build process copy the config file into one of the classpath location.
Hope this helps.
Add the below line in config.groovy
grails.config.locations = [ "classpath:grails-app-config.properties"]
environments {
development {
grails.logging.jul.usebridge = true
grails.config.locations = ["file:C:\\conf\\externalfile.groovy"]
}
production {
grails.logging.jul.usebridge = false
grails.config.locations = ["file:/opt/config/externalfile.groovy"]
// TODO: grails.serverURL = "http://www.changeme.com"
}
}
If you want to access any property from external configuration(config.groovy) then just declare the property like
property = property value eg:(ImagePath = "C:\\Users\\Saved Pictures")
access it like grailsApplication.config."property"
eg:(grailsApplication.config.ImagePath)
NOTE: dont use def just a property and its value.
