Does anybody know what is the best approach to accessing a sql view through Grails (or if this is even possible)? It seems an obvious way of doing this would be to use executeQuery against the view to select a collection of rows from the view which we would not treat as a list of domain objects. However, even in this case it is not obvio...
I'm trying to mix-in a class in my Groovy/Grails app, and I'm using the syntax defined in the docs, but I keep getting an error. I have a domain class that looks like this: class Person { mixin(ImagesMixin) // ... } It compiles fine, but for some reason it won't work. The file containing ImagesMixin is located in my /src/groovy/...
There are essentially 2 places to define JavaScript functions in Grails, directly in a element on the GSP, and within a separate javascript source file under /web-app/js (for example, application.js). We have defined a commonly reused javascript function within application.js, but we also need to be able to generate parts of the functio...
Per an answer to a previous question (answer here: http://stackoverflow.com/questions/425294/sql-database-views-in-grails#427691), I have tried to use a domain class to represent a view in my database. This works wonderfully in most cases, however: I have a view with no single unique key. Let's say the underlying tables look like this: ...
I'm using Grails 1.1 beta2. I need to import a large amount of data into my Grails application. If I repeatedly instantiate a grails domain class and then save it, the performance is unacceptably slow. Take for example importing people from a phone book: for (each person in legacy phone book) { // Construct new Grails domain class f...
In a Grails domain class, how do I set the constraint for a String field so that its MySQL column type is TEXT or LONGTEXT? So far my best approach is to set the constraint's size: myTextField(size:0..65535) which results in TEXT myTextField(size:0..2147483646) results in LONGTEXT (2147483646 = 2^32 / 2 - 1 - 1) Is there a clean...

I'm doing my first experiments with Grails and am looking for a way to have fields represented by a combobox (such as one-to-one domain associations and numbers with a narrow range constraint) to be optional, i.e. there should be an empty entry in the combobox. How can this be achieved? I've tried both adding a nullable:true constraint ...
Let's say I have a class called Store that has many Employees. My RESTful listXML method looks like this: def listXML = { render Store.list() as XML } And the result looks like this: <stores> <store id="1"> <name>My Store</name> <employees> <employee id="1" /> </employees> </store> </store> My question is, how...
I am writing my first taglib as part of a plugin and I would like to document it. Adding javadoc (is there any place that documents groovydoc or is it really the same thing?) doesn't seem to work for non-methods. Specifically, is it possible to document the def mytag in: /** * This doc shows up */ class MyTagLib { static namespace ...

When using Grails 1.0.4 together with a MySQL the charsets of the auto-generated database tables seem to default to ISO-8859-1. I'd rather have everything stored as pure UTF-8. Is that possible? From the auto-generated database definitions: ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=latin1; Note the "latin1" part. ...

I'm writing a small Grails app, and I keep on getting StaleObjectStateException:s for about 1/10:th of the calls to "createfoo" when running the following rather simple code.
