    <p>How can I initialize a <code>static</code> variable with a value defined in <code>config.groovy</code>?</p> <p>Currently I have something like this:</p> <pre class="lang-js prettyprint-override"><code>class ApiService { JSON get(String path) { def http = new HTTPBuilder("${grailsApplication.config.grails.api.server.url}") ... } JSON get(String path, String token) { def http = new HTTPBuilder("${grailsApplication.config.grails.api.server.url}") ... } ... JSON post(String path, String token) { def http = new HTTPBuilder("${grailsApplication.config.grails.api.server.url}") ... } } </code></pre> <p>I don't want to define the <code>http</code> variable inside each method (several GET, POST, PUT and DELETE). </p> <p>I want to have the <code>http</code> variable as a <code>static</code> variable inside the service.</p> <p>I tried this without success:</p> <pre class="lang-js prettyprint-override"><code>class ApiService { static grailsApplication static http = new HTTPBuilder("${grailsApplication.config.grails.api.server.url}") JSON get(String path) { http.get(...) ... } } </code></pre> <p>I get <code>Cannot get property 'config' on null object</code>. The same with:</p> <pre class="lang-js prettyprint-override"><code>class ApiService { def grailsApplication static http ApiService() { super() http = new HTTPBuilder("${grailsApplication.config.grails.api.server.url}") } JSON get(String path) { http.get(...) ... } } </code></pre> <p>Also I tried without a <code>static</code> definition, but the same error <code>Cannot get property 'config' on null object</code>:</p> <pre class="lang-js prettyprint-override"><code>class ApiService { def grailsApplication def http ApiService() { super() http = new HTTPBuilder("${grailsApplication.config.grails.api.server.url}") } } </code></pre> <p>Any clue?</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.
