Grails & 'Grails in Action' - some notes & comments

I have just started playing with grails.

I am using 'Grails in Action' as my reference.

My current version of grails is 1.3.4

I am using the STS eclipse IDE with their built in grails plugin

Here are some initial notes on GOTCHAs I have found with the book and grails itself.

NB I will continue to update this one page with other gotchas, instaed of creating many pages.

Comments on 'Grails in Action'

1) p28, list 1.22

'render' should be 'response.outputStream <<'

2) logo.png & snazzy.css are needed for chapt 1 & can be got from github

Comments on Grails 1.3.4

1) can not create integration tests - getting error

Error executing script CreateIntegrationTest: No such property: type for class: CreateIntegrationTest

No such property: type for class: CreateIntegrationTest

edit the file scripts/CreateIntegrationTest.groovy in your grails installation

and add the line

def type = "Tests"

after the line

depends(checkVersion, parseArguments)

solution from http://jira.codehaus.org/browse/GRAILS-6606

NB this is fixed in 1.3.5

2) when running the test via 'grails test-app' the url for the report is incorrect

and is missing the trailing 's' from the URL

edit the file scripts/_GrailsTest.groovy line 402 and add a space after the the closing brace of testReportsDir and before the double quote

msg += " - view reports in ${testReportsDir} "

3) 1.3.5 bug - add a contraint that specifies the size of the field then it does not check for null.

IE This will allow a nulll value in name:

static constraints = {
   name (size:3..8)
 }

The work around is to do this:

static constraints = {
  name (size:3..8, blank:false)
}

bug GRAILS-6821 has been raised on version 1.3.5
