How can I write this code correctly in Groovy / Gorm?
I have a PageComponent domain class that has many Content 's. I want to see if a particular PageComponent contains a Content with a specfific key .
I thought I could say:
def pageComponent = PageComponent.get(1);
if (pageComponent.contents.findByKey("textnode") {
// update
} else {
// insert
}
At the moment, I'm using this instead. Not very elegant...
def pageComponent = PageComponent.get(1);
def content = Content.withCriteria {
eq "pageComponent.id", pageComponent.id
eq "key", "textnode"
}
您还可以使用动态查找器:
Content.findByPageComponentAndKey(pageComponent, "textnode")
