First of all, I am new to both Grails and Vaadin, I'm trying to make it work according to docs. I am using Grails 2.2.4 and Vaadin 7.1.8.2. I installed the plugin using:
$ grails install-plugin vaadin 7.1.8.2
and put the plugin into BuildConfig.groovy:
compile ':vaadin:7.1.8.2'
I have made a basic Vaadin UI that works (even generated from Eclipse designer - great stuff), I can modify it and it auto-reloads. Fine. I got the URL mapping set in VaadinConfig.groovy so that I can use the traditional Grails CRUD controllers as well as my Vaadin UI:
mapping = [
"/vaadin": "app.MyUI"
]
contextRelativePath = "/vaadin"
I was hoping I could use the Vaadin-style CRUD scaffolding of domain classes as in http://mckenfra.github.io/grails-vaadin-plugin/source-code/docs/ref/Command%20Line/generate-vaadin-all.html but I can't generate it:
$ grails generate-vaadin-all "*"
| Script 'GenerateVaadinAll' not found, did you mean:
1) GenerateAll
2) GenerateViews
3) GenerateController
4) DbmGenerateChangelog
5) DbmGenerateGormChangelog
I'm getting the same if I try generate-vaadin-views or generate-vaadin-controllers. What could I be doing wrong ?
Thanks
You can try RefreshDependencies before GenerateVaadinAll.

I have a large number of Grails 2.5 applications that I want to upgrade to Grails 5, but have been unable to get the configuration to work. In particular, I want my plugin to set up the data source and Spring Security configuration as it did in Grails 2.5.
In my Grails 2.5 applications, I was able to add files to the configuration by adding this code to the top of Config.groovy.
if (!grails.config.location || !(grails.config.location instanceof List)) {
grails.config.location = []
}
grails.config.location << ["classpath:jcc-server-config.properties"]
grails.config.location << ["classpath:SecurityConfig.groovy"]
But this doesn't work in Grails 5. I've tried adding an application.groovy file, but everything defined in the application.yml seems to be set in stone. Has anybody found a way to add a Groovy file to the Grails configuration that will override or add to the settings in application.yml? YAML will not do because I have logic embedded in the configuration to make it work correctly in different environments.
Thanks.
Did you remember to include the external-config dependency? i.e.
implementation 'dk.glasius:external-config:3.0.0'
Re' your question on accessing config values this way, there should be no difference, in my apps I get to the config either via grailsApplication.config, or if grailsApplication isn't immediately available(e.g. classes under src), then with Holders, i.e. Holders.grailsApplication.config.
Grails 5 is using the fields-plugin (as stated in the scaffolding plugin and I see it in the Intellij-IDEA Grails-View of my project under plugins).
But how can I install the fields-plugin templates?
Even in the GitHub-sources I could only find the templates for _embedded, _list and _table.
what am I missing?
(The reason for all that is, that I want to know, how the inList constraint is handled in a g:select. I know it's working, but if I try it the "old-fashioned" way with
from=${MyDomain.constraints.myField.inList}
grails throws errors Cannot get property 'myField' on null object
Please correct me if I'm wrong, but the delivered plugin has no other template files as the mentioned ones, the base "template" is done through the taglib and you can override with "self-made" tag-gsps in views.
But I would like to see some documentation, which variables you could use in own template-files... or did I miss it?
The constraints attribute has changed to constrainedProperties.
I'am new to grails, I wanted to make use of Dynamic Controller Plugin (http://grails.org/plugin/dynamic-controller) in my project.
I am using grails version 3.2.11
I've added the dependency as directed on the page. It downloads the dependency in the form of zip, I can see it in External libraries. But when I am trying to import two classes (as directed on http://burtbeckwith.com/blog/?p=1041 Linking to existing Controller Actions
approach)
import com.burtbeckwith.grails.plugins.dynamiccontroller.ControllerClosureSource
import com.burtbeckwith.grails.plugins.dynamiccontroller.DynamicControllerManager
it gives " unable to resolve class" error. Please suggest what am I doing wrong here. Thanks!
You're trying to install a Grails 2 plugin in a Grails 3+ app, but that's not possible since they're not compatible. Grails 2 plugins must be upgraded and reworked to be used in Grails 3, and there's no plan to do so for this plugin.
I would say take a look at the URL Mappings & Embedded variables in the grails documentation.
https://docs.grails.org/3.2.11/guide/single.html#embeddedVariables
For example:
static mappings = {
"/blog/$topic"(controller: "blog")
}
which gives you a feeling like you are dynamically declaring actions.
And the topic variable is accessible through GrailsParameterMap params object # controller.
With this you can construct url like:
www.mysite.com/blog/football
www.mysite.com/blog/tvshow
www.mysite.com/blog/etc
Edit: you can also take a look at Dynamic Controller and Action Names [https://docs.grails.org/3.2.11/guide/single.html#_dynamic_controller_and_action_names]
i've been looking several guidance about this in Grails official documentation site here
but still i couldn't make it runs well.
Supposed i created two plugin. myplugin-a and myplugin-b .
Each plugin had their own bootstrap that will execute when main app which install those plugins runs. I had include this line of code in MypluginBGrailsPlugin.groovy
def loadAfter = ['myplugin-a']
but still the plugin runs the bootstrap on each plugins with the following order :
myplugin-b -> myplugin-a .
Did i miss something here ?
Any help would be appreciated
You need to use the camel-case syntax of the plugin name: def loadAfter = ['mypluginA']. See https://github.com/grails-plugins/grails-hibernate-plugin/blob/master/HibernateGrailsPlugin.groovy for an example in the Hibernate plugin
Update: as of Grails 1.3.6 one has access to the full domain from Gant scripts.
From the Grails 1.3.6 release notes:
You can now run one or more Groovy scripts from the commandline using the run-script command, e.g.
grails run-script [path-to-script-1] [path-to-script-2]...[path-to-script-n]
This works around the issue in Gant scripts where you can't conveniently access application classes since they're not available in the classpath when the scripts start.
Hi all,
I am new to using Grails (in a real project) and I have a one-off script I need to execute that reads a file and then populates my database.
I wanted the script to run in the context of my grails app, so I used the create-script command. I now understand that makes it a 'Gant' script. The reason for doing so was that I thought it would allow me easy access to all the grails domain good-ness, so that i would be able to do something like this easily:
Car car = new Car(model: 'bar', brand: 'Ford')
car.save()
Here, Car is one of my domain classes and the strings 'bar' and 'Ford' I have retrieved from my file.
The start of my script looks like this:
import com.foo.Car
grailsHome = Ant.project.properties."environment.GRAILS_HOME"
includeTargets << new File ( "${grailsHome}/scripts/Bootstrap.groovy" )
target(main: "a script for storing cars") {
depends(bootstrap, classpath) // code dealing with the file with cars follows
Surprisingly, groovy gives me a java.lang.NoClassDefFoundError: com.foo.Car when I execute the script with the command grails LoadCars
Am I taking the wrong approach, or is there something more simple I am doing wrong?
Any help is appreciated
i know the scripts are useful, and I will probably get hate mail for even suggesting it, but I have just incorporating this kinda of stuff directly into my application in the past.
I have a flag set in my configuration which indicates if the data should be bootstrapped, if so, the bootstrap code looks for a comma delimited file at startup and calls a service method to load up the data.
I've updated the grails run-script Gant script (referred to by Jared above) to work with grails 1.3.5. I'd been meaning to do it for a while, but this question nudged me into finally getting around to it).
Just download the script described in the post, save it in your grails "scripts" directory and you can then run your own groovy script to bootstrap data with:
grails run-script script-path/boostrapMyDataIntoApp.groovy
I've had to do this and you have to create a special script to allow you to access GORM from a standard grails script. See this question for more info. I'm not sure what the current status of the script is under grails 1.3 but the author of the script posted in the comments.
Hans, there are several choices here, assuming you are not out to polish the GANT scripting chops 8^)
So assume that you are doing some integration-mode TDD, correct?
Have you looked into the db-stuff plugin? Actually that one leverages the open source package (extension of the JUnit project) called dbUnit, which is also an outstanding choice, for both Java and Groovy projects.
*db-stuff <0.3.0> -- db schema managment and data import/export. Generate generic schema files and import or export base/seed/test data into your database.
I have traditionally done this as well in the BootStrap depending on the environment - and I try to never let those domain assumptions / constraints get too far out of synch. with my schema.
Here's the canon I'm talking about :
class BootStrap {
def init = { servletContext ->
if (GrailsUtil.environment.equals( GrailsApplication.ENV_DEVELOPMENT )) {
log.info( "Loading sample data for 2010 models..." );
new Car( manufacturer: new Manufacturer( name: "Toyota" ), model: "Prius" )
new Car( manufacturer: new Manufacturer( name: "GM" ), model: "Volt" )
//...
