Gantt batch updates

[Al]

I have config like this:

 

<ganttdatasource ref="ganttdatasource1"
                        :transport-read="ganttRead"
                        :transport-update="ganttUpdate"
                        :transport-create="ganttCreate"
                        :transport-destroy="ganttDestroy"
                        :transport-parameter-map="parameterMap"
                        :transport-submit="ganttSubmit"
                        schema-model-id="id"
                        :schema-model-fields="fields">
</ganttdatasource>

 

From what I can tell from the docs if transport-submit is defined then the create/update/destroy functions should not be fired and all should be batched up into a single call to transport-submit, but this does not happen: transport-submit is never called and transport-update etc. are all called as normal.

Is this a bug or do I misunderstand the operation?

Hi Al,

To batch multiple changes in one, you have to set the batch property of the dataSource to true. Here is a StackBlitz example demonstrating the usage of the mentioned property. If you move the "Software validation" task, you will see that only one request will be sent to the backend but this request contains the changes made in all "Software validation" subtasks.  

Can you check if after adding the discussed above property, the Gantt will start working as expected in your application?

Thanks Petar, setting the batch prop seems to do the trick (I am sure I had tried that before but obviously I was doing something wrong).

 

So the behaviour seems to be that all updates are sent together in one array when batch is true, either to the separate transport-reate/update/destroy handlers, or, if transport-submit is set, then all updates are sent to that handler
