Adding multiple 'category' to properties, services and events

Adding multiple 'category' to properties, services and events

Hello,

Is it possible to add/set multiple category to same property or service? When we define a property in a Thing, there is a provision also to add a Category (which is helpful in organising and searching), so I would like to know if I can put a property/service in multiple category? If yes, then how?

To better understand what I mean please refer the attached screen shot. So in the screen shot I have 2 properties, property t1 has (better to say, I tried to put) category as POLLED, PLOTTABLE while t2 has category as POLLED. What I would want is when I call the service (generic service) 'GetPropertyDefinitions' with category parameter as POLLED, I should get both t1 and t2 (right now I am only getting t2) and when I call the same service with category parameter as PLOTTABLE, I should get only t1 (right now I am getting nothing).

Please suggest if that's possible.

Thanks in advance

Regards

Aditya Mittal

Hello @mneumann,

I got what I was looking for. I should say it was very nearby, but I couldn't just see it :-)

The way to get/read the category of a property is:

me.GetNamedProperties({propertyNames:{"items":["myProp1"]}}).dataShape.fields["myProp1"].category;

Thanks for your support.

Hi,

the Category seems to be based on a STRING variable.

http://support.ptc.com/help/thingworx_hc/thingworx_8_hc/en/#page/ThingWorx%2FHelp%2FComposer%2FThing...

 

I don't think that it will split it into arrays - but it will just consider it as a whole.

It might be an option to write a custom service, which is based on the GetPropertyDefinitons (get back all of them) and then split the Category and filter for the split values.

 

Cheers,

Michael

Hi Michael,

Thanks for your reply. Continuing on your suggestion do you know how can I read the category of a Property? I mean when I checked, I think I found that 'category' field does not belong to aspects. For your reference I am attaching the Property definition from XML, and there since I didn't find category as aspects.category unlike other fields such as 'aspect.isLogged' or 'aspect.isPersistent' so I am thinking that maybe I cannot read category using aspects. I am not sure if my assumption is correct or not.

 

<PropertyDefinition aspect.cacheTime="0.0" aspect.dataChangeType="VALUE" aspect.isLogged="false" aspect.isPersistent="false" aspect.isReadOnly="false" baseType="STRING" category="POLLED PLOTTABLE" description="" isLocalOnly="false" name="t1" ordinal="1"/>

Thanks

Aditya

Hi @amittal-3

you would need this service output and pass it to another service which is then using the

https://www.w3schools.com/jsref/jsref_split.asp split() Method on the category.

With this result you can operate on the category array - e.g. to check or return individual categories.

 

The output of the new custom service can then be used instead of the original GetPropertyDefinitons.

 

Cheers,

Michael

Hello @mneumann,

Thanks for your reply. When you said - 


you would need this service output


what do you mean by "this"? Were you trying to point to some service by which I can get the category of the propert(y/ies)? Because what you said about using the 'split' method, will be helpful once I am able to read the category aspect of the property.

In my previous post what I meant to ask was how can I read/get the category of any property, using some service. To be more specific to get the 'units' aspect of a property I can get it as - 

me.GetNamedProperties({propertyNames:{"items": "myProp1"}}).dataShape.fields[selectedParam].aspects.units

so in similar way how can I read/get 'Category' aspect?

Thanks in advance for bearing with me!!

Aditya

Sorry @amittal-3

thanks for explaining it again - I think I misunderstood something in the beginning.

I'll try to see what can be done here and come back to you.

Hi @amittal-3

That's quite clever. Nice to see it's working for you.

As there isn't really a intuitive default service to retrieve the Category, I've also opened an internal enhancement request with Product Management / R&D to assess if such a service could be implemented in any of the future releases.

 

Cheers,

Michael
