HTTP GET request in Grails with urls
grails,httprequest,grails-controller
I have found the perfect solution right here: Grails pass data to view from controller in PropertiyController.groovy: def index = { def parameter = request.getParameter("address") } and: def create() { def address = params.address; render(view: "form", model:[viewAddress:address]); } The only thing to change additional is to give the input-field the...
grails transactional controller, handling exceptions
If you have the code inside a controller action, you have to keep an eye on 2 things: transactionality (with try/catch/finally etc) what should the action return/render in case of TX-success/-failure. It's complicated enough, so you should put the service calls into another service method, where you have to deal...
Grails validation over own domain
hibernate,grails,grails-domain-class,grails-controller,grails-validation
I'd probably use something like this: validator: { val, obj -> if (obj.recipients.findAll{invoiceType == 'O'}.size() > 1) return "invoiceRecipient.original.max.exceed" This way you should be able to prevent Hibernate from trying to flush dirty objects and in the process revalidate this object....

Grails controller saves the domain item anyways
hibernate,grails,grails-controller
The best way to do this is not to use discard() but instead to use transactions and the native transaction features of your database. I would recommend moving the logic into a service (separating your controller flow code and the logic of your application. Example: class GroupService { @Transactional void...
ERROR context.GrailsContextLoader - Error initializing the application
The problem was with the instance variable def usr = DbUser.findByLoginNameIlike(session.username) // Find DbUser reference to the current user When DashboardController is instantiated, it tries to execute the above line where no session is stored yet (session.username is NULL). Moving this piece of code inside the methods solved the problem....
Grails controller URL not found
grails,model-view-controller,gsp,grails-controller
In your controller put your code like below and see what happens. render( view: "/foo/foo", model: ) If your controller name and the view folder are same then you dont need to give /foo/foo. Just writing "foo" should be fine. PS. I have not tried this now, but it should...

Grails - Saving rejected null even though parameter initialized
grails,null,save,grails-domain-class,grails-controller
Well I managed to solve it... Apparently new DeviceUsage(device: deviceInstance, user: User.get(user), start: new Date(), end: null) leaves start null for whatever reason, so adding du.start = new Date() at the next line fixed it...
How can we get GroovyfirstRowResult to just list values, and not the column headers and without flower braces when shown in .gsp view?
grails,groovy,gsp,grails-controller,grails-services

Update template inside a view rendered from another controller
ajax,grails,render,gsp,grails-controller
I don't think I entirely understand your question, but I think the source of your confusion is that the way you are naming things doesn't follow regular conventions and you're not using the right tools for the job. Let me explain... The methods on Controllers are called Actions. They send...
Filter 'belongsTo' results
grails,groovy,gorm,grails-domain-class,grails-controller
If you want to get all the entries that are active, change the from attribute to: from="${Pagadora.findAllByActivo(true) [sort: 'nombre', order: 'asc']}" This is a dynamic finder. Jeff points out in the comments that the boolean parameter here can be omitted (see examples for findAllBy). If you want to get all...
Grails Controller and URL Mapping Magic
grails,grails-controller,url-mapping,grails-3.0
Grails has the possibility to declare namespaces for Controllers. With this, you can put all your controllers under the namespace 'app', which should result in exactly your second question. See docs for more details. The security restriction then be accomplished with normal spring security settings (@Secured e.g)....

Grails: What is the difference between using actionName and pageScope.actionName inside taglibs?
grails,grails-2.0,gsp,taglib,grails-controller
pageScope. As for the usage in your company code, I guess it depends on how long ago it was written. Referring to docs in 2010 like: grails_pagescope_variable_in_gsps_and_taglibraries and overriding-plugin-templates-in-grails-application there are a few more around people were using it then, can't comment on if it was essential back then.
Grails\Groovy Syntax Sugar not being added in Webflow integration tests on commmand line

Looks like it was test pollution as evidenced by my edit 'When I run the test via command line by itself the test will pass, but if I run all the integration tests it fails'. Turns out other integration tests where using @TestFor and @Mock in them, which you should...
