• grails services :: multiple projects

  - by naveen

  PROBLEM : I have multiple grails projects (lets say appA, appB and appC) : services to be precise I want to run them in a single grails-app.. probably a war deployment, how can i do this? REQUIREMENTS : I want this to be a single app since i am deploying it on cloud and i don't have enough memory to hold all these service instances individually. The reason for multiple grails project is scalability. So that if later on i want to run 10 instance of appA, 3 instance of appB, and 1 instance of aapC; i should be able to do that. EDIT : Can i use something like 0mq, will that be helpful in keeping the services separated from each other. How will i package my service? And reading the docs of 0mq seems that it can work with both inprocess and external process. Will async grails requests on HTTP work with 0mq in process/ external mq calls. Haven't used 0mq, but from the initial doc it seems to work. Need some experience calls in this scenario. Are there any other alternatives or mq alternatives?

• Grails GORM (Hibernate) query

  - by bsreekanth

  Hello, I'm trying to do the below sql statement in GORM select * from table1 where table1.x not in (select x from table 2 where y='something'); so, I have two tables, and needs to find the entries from table 1 which are not in table 2. In Grails def xx= table2.findByY('something') def c = table1.createCriteria() def result= c.list { not ( in('x', xx) ) } the syntax is wrong, and I'm not sure how to simulate not in sql logic. As a learning point, if someone can also tell me why minus (-) operator in grails/groovy doesn't work with list. I tried getting x and y seperately, and doing x.minus(y), but it doesn't change the list. I saw an explanation at http://stackoverflow.com/questions/1754576/groovy-on-grails-list-not-working , but I would expect the list defined are local. thank you so much.

• How do I return an Array from grails / jdo to Flex

  - by mswallace

  this seems really simple but I haven't gotten this to work. I am building my app with grails on google app engine. This pretty much requires you to use JDO. I am making an HTTP call from flex to my app. The action that I am calling on the grails end looks like so def returnShowsByDate = { def query = persistenceManager.newQuery( Show ) def showInstanceList = query.execute() return (List<Show>) showInstanceList } I have tried just returning "hello from grails" and that works just fine. I have alos tried the following return showInstanceList the JDO docs say the query.execute() returns a collection. Why I cant just return that to Flex I have no clue. Any thoughts?

• Maintaining both sides of self-referential many-to-many relationship in Grails domain object

  - by Ali G

  I'm having some problems getting a many-to-many relationship working in grails. Is there anything obviously wrong with the following: class Person { static hasMany = [friends: Person] static mappedBy = [friends: 'friends'] String name List friends = [] String toString() { return this.name } } class BootStrap { def init = { servletContext -> Person bob = new Person(name: 'bob').save() Person jaq = new Person(name: 'jaq').save() jaq.friends << bob println "Bob's friends: ${bob.friends}" println "Jaq's friends: ${jaq.friends}" } } I'd expect Bob to be friends with Jaq and vice-versa, but I get the following output at startup: Running Grails application.. Bob's friends: [] Jaq's friends: [Bob] (I'm using Grails 1.2.0)

• Persist url parameter throughout grails app

  - by avelis

  Essentially I am looking to have a url query parameter persist throughout the life of the grails application (POST or GET). ex. http://localhost:8080/demo/controller/action/?myParam=foobar I have tried a couple routes. Dynamic method overriding redirect and customizing application tags for createLink. However, since I also use grails webflows it doesn't quite get every single URL. I also tried using a groovy servlet (groovlet) to capture every URL and append the query parameter. The last attempt hasn't been very successful. Am I missing an obvious component to grails? Am I on the right track? Is there another avenue I haven't explored yet? Thanks in advance

• Trouble enabling Grails logging

  - by Dave

  I have this logging configuration in my Config.groovy file. This is a development environment, started as such. I have verified the file exists and there are 775 perms on the file, but nothing is getting output to the file. // set per-environment serverURL stem for creating absolute links environments { production { grails.serverURL = "http://www.changeme.com" } development { grails.serverURL = "http://localhost:8080/${appName}" logFilePath = "/Users/davea/Tomcat/logs/log4j.log" } test { grails.serverURL = "http://localhost:8080/${appName}" } } // log4j configuration log4j = { console name:'Appender1', layout:pattern(conversionPattern: '%-4r [%t] %-5p %c %x - %m%n') rollingFile name:'Appender2', maxFileSize:1024 * 1024, file:logFilePath, layout:pattern(conversionPattern: '%-4r [%t] %-5p %c %x - %m%n') root { debug 'Appender1', 'Appender2' } } Can anyone tell what's wrong with my configuration? Thanks, - Dave

• Custom Grails Environments?

  - by tinny

  I have been developing several Grails applications over the past couple of years. I am increasingly finding that the three grails environments (dev, test, prod) aren't enough to satisfy my needs. The more "enterprisey" your application gets, the more environments you tend to have. I tend to use 6 environments for my development cycle... DEVA //My dev DEVB //Team mates dev CI_TEST //CI like Hudson QA_TEST //Testing team environment UAT_TEST //Customers testing environment PROD //Production Im wondering if there is a way to define custom Grails environments? I dont think there is, but the feature could be handy. The way I am getting around this right now is by externalising the config to a properties file. Id imagine that this is a pretty common requirement, so how have you been dealing with your environments?

• Grails application hogging too much memory

  - by RN

  Tomcat 5.5.x and 6.0.x Grails 1.6.x Java 1.6.x OS CentOS 5.x (64bit) VPS Server with memory as 384M export JAVA_OPTS='-Xms128M -Xmx512M -XX:MaxPermSize=1024m' I have created a blank Grails application i.e simply by giving the command grails create-app and then WARed it I am running Tomcat on a VPS Server When I simply start the Tomcat server, with no apps deployed, the free memory is about 236M and used memory is about 156M When I deploy my "blank" application, the memory consumption spikes to 360M and finally the Tomcat instance is killed as soon as it takes up all free memory As you have seen, my app is as light as it can be. Not sure why the memory consumption is as high it is. I am actually troubleshooting a real application, but have narrowed down to this scenario which is easier to share and explain.

• Grails multi column indexes

  - by Kimble

  Can someone explain how to define multi column indexes in Grails? The documentation is at best sparse. This for example does not seem to work at all: http://grails.org/GORM+Index+definitions I've had some luck with this, but the results seems random at best. Definitions that works in one domain class does not when applied to another (with different names of course). http://www.grails.org/doc/1.1/guide/single.html#5.5.2.6%20Database%20Indices Some working examples and explanations would be highly appreciated!

• Doing a generic <sql:query> in Grails

  - by melling

  This is a generic way to select data from a table and show the results in an HTML table using JSP taglibs. What is the generic way to do this in Grails? That is, take a few lines of SQL and generate an HTML table from scratch in Grails, including the column names as headers. <sql:query var="results" dataSource="${dsource}" select * from foo </sql:query (# of rows: ${results.rowCount}) <table border="1" <!-- column headers -- <tr bgcolor=cyan <c:forEach var="columnName" items="${results.columnNames}" <th<c:out value="${columnName}"/</th </c:forEach </tr <!-- column data -- <c:forEach var="row" items="${results.rowsByIndex}" <tr <c:forEach var="column" items="${row}" <td<c:out value="${column}"/</td </c:forEach </tr </c:forEach </table The solution to this was answered in another StackOverFlow question. http://stackoverflow.com/questions/425294/sql-database-views-in-grails IF SOMEONE WRITES A GOOD ANSWER, I'LL ACCEPT IT. I would like a 100% acceptance on all of my questions.

• URL Mapping prefix in Grails

  - by Furuno

  Recently, I'm trying to migrating my application from CakePHP to Grails. So far it's been a smooth sailing, everything I can do with CakePHP, I can do it with much less code in Grails. However, I have one question : In CakePHP, there's an URL Prefix feature that enables you to give prefix to a certain action url, for example, if I have these actions in my controller : PostController admin_add admin_edit admin_delete I can simply access it from the URL : mysite/admin/post/add mysite/admin/post/edit/1 mysite/admin/post/delete/2 instead of: mysite/post/admin_add mysite/post/admin_edit/1 mysite/post/admin_delete/2 Is there anyway to do this in Grails, or at least alternative of doing this?

• Teamcity and Grails

  - by WaZ

  Hi there, My current requirement is: I have to package my grails app and use teamcity for continuous build. The only problem is the build agents don't have groovy and grails installed (don't ask why) I want to package my app with Groovy and Grails directories and check in Git. So that there is no dependency. And the package has everything to run the app. Can anybody please help. Please let me know if you want me to rephrase my question.

• Can layouts be chosen by Grails controllers?

  - by maerics

  I'm building a CMS as a learning exercise in Grails and would like to give content managers the ability to choose between different HTML page structures (e.g. 2 column, 3 column, etc). Grails Layouts seem like a logical choice but is it possible for a Grails controller to explicitly name which layout will be used for rendering? Ideally there would be a layout option to the render method, per Ruby on Rails but I don't see anything like it. It seems like it might be possible using the applyLayout method by passing the name of the layout but this requires each GSP page to explicitly request layout (annoying overhead per-page) rather than using Layout by Convention. Any ideas?

• Grails - Language prefix in url mappings

  - by Art79

  Hi there im having problem with language mappings. The way i want it to work is that language is encoded in the url like /appname/de/mycontroller/whatever If you go to /appname/mycontroller/action it should check your session and if there is no session pick language based on browser preference and redirect to the language prefixed site. If you have session then it will display english. English does not have en prefix (to make it harder). So i created mappings like this: class UrlMappings { static mappings = { "/$lang/$controller/$action?/$id?"{ constraints { lang(matches:/pl|en/) } } "/$lang/store/$category" { controller = "storeItem" action = "index" constraints { lang(matches:/pl|en/) } } "/$lang/store" { controller = "storeItem" action = "index" constraints { lang(matches:/pl|en/) } } "/$controller/$action?/$id?"{ lang="en" constraints { } } "/store/$category" { lang="en" controller = "storeItem" action = "index" } "/store" { lang="en" controller = "storeItem" action = "index" } "/"(view:"/index") "500"(view:'/error') } } Its not fully working and langs are hardcoded just for now. I think i did something wrong. Some of the reverse mappings work but some dont add language. If i use link tag and pass params:[lang:'pl'] then it works but if i add params:[lang:'pl', page:2] then it does not. In the second case both lang and page number become parameters in the query string. What is worse they dont affect the locale so page shows in english. Can anyone please point me to the documentation what are the rules of reverse mappings or even better how to implement such language prefix in a good way ? THANKS

• Grails: Querying Associations causes groovy.lang.MissingMethodException

  - by Paul

  Hi, I've got an issue with Grails where I have a test app with: class Artist { static constraints = { name() } static hasMany = [albums:Album] String name } class Album { static constraints = { name() } static hasMany = [ tracks : Track ] static belongsTo = [artist: Artist] String name } class Track { static constraints = { name() lyrics(nullable: true) } Lyrics lyrics static belongsTo = [album: Album] String name } The following query (and a more advanced, nested association query) works in the Grails Console but fails with a groovy.lang.MissingMethodException when running the app with 'run-app': def albumCriteria = tunehub.Album.createCriteria() def albumResults = albumCriteria.list { like("name", receivedAlbum) artist { like("name", receivedArtist) } // Fails here maxResults(1) } Stacktrace: groovy.lang.MissingMethodException: No signature of method: java.lang.String.call() is applicable for argument types: (tunehub.LyricsService$_getLyrics_closure1_closure2) values: [tunehub.LyricsService$_getLyrics_closure1_closure2@604106] Possible solutions: wait(), any(), wait(long), each(groovy.lang.Closure), any(groovy.lang.Closure), trim() at tunehub.LyricsService$_getLyrics_closure1.doCall(LyricsService.groovy:61) at tunehub.LyricsService$_getLyrics_closure1.doCall(LyricsService.groovy) (...truncated...)

• Externalizing Grails Datasource configuration

  - by miek

  Grails 1.x allows using external configuration files by setting the grails.config.locations directive. Is there a similar approach available for externalizing the database configuration in Datasource.groovy (without setting up JNDI)? It would prove helpful to be able to configure DB credentials in a simple configuration file outside the application. Thanks in advance!

• PartialResultException when authenticating over LDAP with Acegi and Grails

  - by Benny Hallett

  I'm trying to setup our new Grails application to authenticate via LDAP. From the logs we can see that Acegi is binding to the LDAP store, then is able to find the user given the correct credentials, and finally begins searching for roles. The authentication fails due to a PartialResultException. I'm aware that the default LDAP provider in Acegi has an option to ignore PartialResultExceptions, but I'm not exactly sure how to turn that on in Grails.

• Custom string formatting in Grails JSON marshaller

  - by ethaler

  I am looking for a way to do some string formatting through Grails JSON conversion, similar to custom formatting dates, which I found in this post. Something like this: import grails.converters.JSON; class BootStrap { def init = { servletContext -> JSON.registerObjectMarshaller(String) { return it?.trim() } } def destroy = { } } I know custom formatting can be done on a per domain class basis, but I am looking for a more global solution.

• Result set mapping in Grails / GORM

  - by armandino

  I want to map the result of a native SQL query to a simple bean in grails, similar to what the @SqlResultSetMapping annotation does. For example, given a query select x.foo, y.bar, z.baz from //etc... map the result to class FooBarBaz { String foo String bar String baz } Can anyone provide an example of how to do this in grails? Thanks in advance.
