Hi, I've got an entity including a one numeric field. Now, I would like to sum values of this entity for all it's records. How can I do it? Thanks in advance for help.

Hi,

in WebRatio 6.1 you can define the Aggregate/Imported Attributes directly on the unit. You can see an example in the WebRatio Release Notes (Help > WebRatio Release Notes)

If you prefer write and execute a custom query, you can add a Query Unit to your model. For more details you can read this article: Getting started with the Query Unit

There is another way, in fact you can refer to this article of our wiki: The derivation in the data model

In this case you can use a Calculated Attribute.

Thank you Alberto. Extending the question, I currently have a simple list each showing a particular aggregation of attributes. How can I add text after each aggregated result for example, '64 people have subscribed'. 64 being the only result being shown currently. Am I using the wrong view component?

Thanks,
Arjun
