grails-3.0

问题 I have the following Domain class with derived property lowercaseTag . class Hashtag { String tag String lowercaseTag static mapping = { lowercaseTag formula: 'lower(tag)' } } If I run the following unit test, it will fail on the last line, because lowercaseTag property is null and by default all properties have nullable: false constraint. @TestFor(Hashtag) class HashtagSpec extends Specification { void "Test that hashtag can not be null"() { when: 'the hashtag is null' def p = new Hashtag

问题 So I downloaded Grails 3 M1 and created a project. There's no DataSource.groovy, even after the MySQL driver was added to the dependencies - I thought maybe it will see the driver and know a DataSource.groovy is needed. Secondly, plugins. I found the Grails 3 plugin page (https://github.com/grails3-plugins) How does one go about installing these? Is there a new repository? E.g. the newest Scaffolding plugin on Maven is from March 2014. Will the older plugins still work? Thanks. 回答1: Starting

问题 It looks like IntelliJ's (Ultimate EAP 15) support for Grails 3 is in the early stages yet. If I do Run -> Debug 'Grails:My App' , I'm able to launch an app from inside IntelliJ, I can set breakpoints and it works as expected. If I make changes however, I see in the console that the file is recompiled, but when I hit reload in the browser, I don't see the changes reflected there. I have to stop and restart the app in IntelliJ before I see them. Anyone know how I can get the auto-reloading

问题 I'm almost certain this is a stupid question but I do not know the answer to it :) I'm in the process of upgrading a project of mine from Grails 2.5 to 3 and trying to get to grips with the new inline plugin structure, the old way was working fine but struggling to get the new way working. I have a directory structure as follows: / /settings.gradle /myApp #contains a grails 3 application /myPlugin1 #contains a grails 3 plugin /myPlugin2 #contains a grails 3 plugin /settings.gradle contains:

问题 There's documentation on IntelliJ's website for creating a new Grails project, but importing a project is more sketchy and I cannot get it to work for me. If I tell IntelliJ to import a new project, and point it to my project directory, it does not recognize it as a Grails project. After the project imports, I can go to the Project menu, right click on the project and go to "add Framework support..." and select Groovy, but IntelliJ still does not recognize my project as a Grails project.

问题 It appears that the spring reloading causes errors with JDK 8u40 in Grails 3.0.0.M2. Can I disable the reloading in development mode? Is there a key to set in the build.gradle or in the application.yml? 回答1: Not sure if it helps in above case. I use below over grails 2.3.8 to disable auto compile. grails -Dserver.port=8090 -Dserver.env=development -Denable.jndi=true -Ddisable.auto.recompile=true run-app where disable.auto.recompile=true disables autocompile and autoreload of changes . server

问题 In grails 3 application, I see that new java.time classes are persisted to database. Dynamic queries and create criteria works. However, I am wondering if there is some better way how to store these time data to database. When I look to database I see some binary data, it seems it just serialize the time objects. Is there any similar plugin as joda-time-plugin or is there any way how to configure database mapping for java.time classes? 回答1: Edit : Grails 3.1.1 has hibernate 5 so this is not

问题 I am trying to create a simple Grails 3 project and got stuck with something really simple. So I want my data source properties to come from VM options that I set in my IntelliJ IDE. Before in Grails 2.x, I just used to do something like: environments { development{ //Database connection properties def dbserver = System.properties.getProperty('dbserver') def dbport = System.properties.getProperty('dbport') ............ dataSource { url: "jdbc:sqlserver://${dbserver}:${dbport};databaseName=$
