Sling Model Binary Inject

Avatar

Level 10

Hi,

 

trying to adapt to resource class and i have a binary field with @inject. I try accessing the binary field and it says org.apache.sling.models.impl.injectors.ResourcePathInjector Could not retrieve resource at path {{the values stored at the variable }} for field {{property name}}. Since it is required it won't be injected.

 

So tried adapting to valuemapvalue,error is gone but the property is null  or does not exist

any inputs?

I would say adapt as resource or then read the binary property using InputStream.

I did the same but are you trying to say adapt the property as resource? Can you please elaborate and give some more details on how this can be done 

 

nodeA has property 

binaryprop binary value

 This is a binary property on a node say custom .. and custom is adapted as a resource . @arunpatidar  

with that, the value is null

apologies if I am not able to follow

Sure .. 

/content

  /xxx

    /page

       /jcr:content

          /par

              /samplenode(node)

                     (Not a node) binaryproperty binary binaryval

 

samplenode is adapted as a resource class

Hi Arun

thanks,
Maybe I didn state the concern well.. my concern is more of adapting the node samplenode of my:unstructured type to a resource class via sling model and getting the binary property Into it 

 

 

what i observed is that other custom properties injected were retrieved but not the binary, I had taken the route of creating init method within sling model and obtaining the binary by reading the property from node path again via resolver.getresource(node path)  

that worked but if I do a get on the binary property that does not work

Hi @NitroHazeDev 
could you please share your code which you are you using to retrieve Binary property inside init method?

Hi @arunpatidar    "samplenode" in the above structure is adapted to a resource, and its properties, path and binaryPath are injected..

 

@Model(adaptables = Resource.class,defaultInjectionStrategy=DefaultInjectionStrategy.OPTIONAL)
public class customModel {


@Inject
private String path;

 

@Self
private Resource resource;

@SlingObject
private ResourceResolver resolver;

 

@ValueMapValue(injectionStrategy=InjectionStrategy.OPTIONAL)
private Binary binaryProperty;

 

//Getters for the properties

 

@PostConstruct
protected void init() {

//use the getter to get the binary property or use this. and no //result

 

//alternatively use below and it works

content = resolver.getResource(resource.getPath()).adaptTo(Node.class).getProperty("binaryProperty").getStream();

}

}

@arunpatidar so in the above the injections or valuemap for binary does not seem to work 

kindly let me know

Hi @NitroHazeDev 
Please check https://stackoverflow.com/questions/16932789/accessing-resource-data-from-jcr-repo

 

You can try adapting to Property

@ValueMapValue(injectionStrategy=InjectionStrategy.OPTIONAL)
private Property binaryProperty;

Binary b = (null != binaryProperty) ? binaryProperty.getBinary() : null;
