    text
    copied!<p>I followed the instruction here: <a href="http://www.grails.org/doc/latest/guide/7.%20Validation.html" rel="nofollow">http://www.grails.org/doc/latest/guide/7.%20Validation.html</a></p> <p>and added into <strong>config.groovy</strong>:</p> <pre><code>grails.validateable.classes = [liningtest.Warm'] </code></pre> <p>Then added in <strong>src/groovy/Warm.groovy</strong> (it's a non-persistent domain class):</p> <pre><code>package liningtest import org.codehaus.groovy.grails.validation.Validateable class Warm { String name; int happyCite; Warm(String n, int h) { this.name = n; this.happyCite = h; } static constraints = { name(size: 1..50) happyCite(min: 100) } } </code></pre> <p>But it just doesn't work (both "blank false" &amp; "size: 0..25") for the "hasErrors" function. It always returns false, even when the name is > 25.</p> <p>Is this a Grails bug, if yes, is there any work-around?</p> <p>I'm using Grails 1.3.3</p> <p><strong>UPDATE</strong>: I have updated the simplified code. And now I know that constraint "size" can't be used with "blank", but still does not work.</p> <p>My test class in <strong>test/unit/liningtest/WarmTests.groovy</strong></p> <pre><code>package liningtest import grails.test.* class WarmTests extends GrailsUnitTestCase { protected void setUp() { super.setUp() } protected void tearDown() { super.tearDown() } void testSomething() { def w = new Warm('Hihi', 3) assert (w.happyCite == 3) assert (w.hasErrors() == true) } } </code></pre> <p>And the error I got:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8" ?&gt; &lt;testsuite errors="1" failures="0" hostname="evolus-50b0002c" name="liningtest.WarmTests" tests="1" time="0.062" timestamp="2010-12-16T04:07:47"&gt; &lt;properties /&gt; &lt;testcase classname="liningtest.WarmTests" name="testSomething" time="0.062"&gt; &lt;error message="No signature of method: liningtest.Warm.hasErrors() is applicable for argument types: () values: [] Possible solutions: hashCode()" type="groovy.lang.MissingMethodException"&gt;groovy.lang.MissingMethodException: No signature of method: liningtest.Warm.hasErrors() is applicable for argument types: () values: [] Possible solutions: hashCode() at liningtest.WarmTests.testSomething(WarmTests.groovy:18) &lt;/error&gt; &lt;/testcase&gt; &lt;system-out&gt;&lt;![CDATA[--Output from testSomething-- ]]&gt;&lt;/system-out&gt; &lt;system-err&gt;&lt;![CDATA[--Output from testSomething-- ]]&gt;&lt;/system-err&gt; &lt;/testsuite&gt; </code></pre> <p><strong>UPDATE 2</strong>: When I don't use Unit test, but try to call <strong><em>hasErrors</em></strong> in the controller, it runs but return false value. (hasErrors return false with Warm('Hihi', 3) ). Does anyone has a clue?</p> <p><strong>UPDATE 3</strong>: I followed Victor way, and now the problem is solved if I call validate() before hasErrors(). But I still don't understand, why "grails generate-all" controllers doesn't have to call validate() before using hasErrors()?</p>
