Re: Given a resource URI, how to find out which group it belongs to in wro4j

[Alex Objelean]

The WroModel can be accessed using WroModelFactory. 

You can inspect the model by iterating on available groups collections and find if a particular resource is part of the group. 

If you find it useful, the WroModel will be added a new method: List<Group> getGroupsOfResource(Resource resource);

Thank you. It would be easier with an api instead. Will update you how it goes. Thanks again.

Ok, I'll add a new method which will expose this information in WroModel.

Cheers,

Hi,

How can I access the WroModel from a spring bean ? I was using the following code and it is erroring out saying "No context associated with CURRENT request cycle!";

      ServletContextAttributeHelper helper =  new ServletContextAttributeHelper(m_context);
        WroManagerFactory wroManagerFactory = helper.getManagerFactory();
        WroManager wroManager = wroManagerFactory.create();    // This is the line where error is occuring !


        WroModelFactory wroModelFactory = wroManager.getModelFactory();
        WroModel wroModel = wroModelFactory.create();
        Collection<Group> groups = wroModel.getGroups();
        for (Group group : groups) {
            List<Resource> resources = group.getResources();
            for (Resource resource : resources) {
                m_map.put(resource.getUri(), group.getName());
            }
        }

Thank you.

Every operation performed by wro4j requires to access the Context object (the one which contains details about current request). The model can be inspected only during the request. You can find more details on this page: http://code.google.com/p/wro4j/wiki/WroServletContextListener  (@see AddWroContextFilter to web.xml section).

It is possible to access the model outside the request filter, but it won't be the same instance used by wro4j. You can build it using XmlModelFactory and loading from the location where the wro.xml is stored or GroovyModelFactory for loading wro.groovy file. Find more about model on wiki: http://code.google.com/p/wro4j/wiki/WroModel

Cheers,

Hi,

Making your bean request or session scoped should help.

That's true, but you still have to map WroFilter to /* or similar in order to make the Context available.
