    <p>I am new to grails and I have a question about limiting a query result: domain User:</p> <pre><code>class User { String login String password String fname String lname String role = "user" static constraints = { login (size:5..15, blank:false, unique:true, matches:"[a-zA-Z0-9]+") password (size:5..15, blank:false) fname (blank:false) lname (blank:false) role (inList:["user", "admin"]) } String toString(){ fname &amp; " " &amp; lname } static mapping = { cache true columns { fname type:'text' lname type: 'text' password type:'text' login type:'text' } } } </code></pre> <p>my GSP page snippet that displays the results:</p> <pre><code>&lt;g:each in="${userInstanceList}" status="i" var="userInstance"&gt; &lt;tr class="${(i % 2) == 0 ? 'odd' : 'even'}"&gt; &lt;td&gt;&lt;g:link action="show" id="${userInstance.id}"&gt; ${fieldValue(bean: userInstance, field: "id")}&lt;/g:link&gt;&lt;/td&gt; &lt;td&gt;${fieldValue(bean: userInstance, field: "login")}&lt;/td&gt; &lt;td&gt;****&lt;/td&gt; &lt;td&gt;${fieldValue(bean: userInstance, field: "fname")}&lt;/td&gt; &lt;td&gt;${fieldValue(bean: userInstance, field: "lname")}&lt;/td&gt; &lt;td&gt;${fieldValue(bean: userInstance, field: "role")}&lt;/td&gt; &lt;/tr&gt; &lt;/g:each&gt; </code></pre> <p>I call the controller with this code, in separate gsp view:</p> <pre><code>&lt;g:link class="users" controller="user" params="[sort:'fname',order:'desc']" action=""&gt;Manager Users&lt;/g:link&gt; </code></pre> <p>My question is, how do I call the domain and display the results according to the following criteria: first, if the Role is admin, display everything. If the role is not admin, only display the results of certain login value (ie, just show the results where the login = the current user)</p> <p>Thanks for your help! jason</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
