How can I retrieve and handle an object set in Slate that was passed through from a Workshop module via an iframe widget, especially when dealing with a large number of objects?

To retrieve and handle an object set in Slate that was passed through from a Workshop module via an iframe widget, follow these steps:

1. Use slate.getMessage to get the filter payload. The code snippet for this step is:

   const payload = {{slEventValue}};
   return payload["workshop_variable_name"]
   

2. Set a Slate variable with the payload for the filter spec.

3. Query the object set service with the following body, replacing {{slate_var}} with your variable name:

   {
       objectSet: "{{slate_var}}",
       pageSize: 50
   }
   

   This will return a list of RIDs (resource identifiers).

4. Use a TypeScript function to retrieve your objects with all properties. The code snippet for this step is:

   Objects().search().yourObject(listOfRids).allAsync()

Note that there is a 100,000 object limit for Objects().search(). If your object set is larger than the pageSize, you'll need to handle pagination by creating a function to go through each paged result. The pageSize can be adjusted based on the number of objects you expect to retrieve and what can be handled by the object service and a user's network.

Why isn't the query running when called from a function, despite running successfully through the UI?

To make the query run when called from a function, you need to either enable "Automatically run this query when the app loads and when its dependencies change" in the query's configuration, or configure an action that triggers the query using Slate events.

What is the best way to embed a single button built in Slate into a Workshop application and adjust the dimensions between the Slate canvas, the button, and the Workshop widget?

You could try different styling options in Slate, such as the iframe and button width, and the styling in Workshop, like widget width/height until the desired output is achieved. If the canvas is too large, you can set the styling on the canvas in Slate to disable scrolling with the following CSS: sl-app-canvas { overflow: hidden; }.

How can I implement a real-time countdown timer in Slate that updates every second?

To implement a real-time countdown timer in Slate that updates every second, you can create a dummy query and configure it to rerun every second.

How can I change a line in a line chart from solid to dashed using CSS?

To change a line in a line chart from solid to dashed, you can create a CSS class and apply the 'stroke-dasharray' property to it. Here's an example of the CSS code you could use:

Copied!
1
2
3
.myCSSClassForLine {
 stroke-dasharray: 4 1 2;
}

Then, you need to ensure that this class is applied only to the specific line you want to be dashed by using the correct selector. You may need to inspect the HTML to find the ID or class of that particular line. Both the dataset name and the series get added as classes, which can be used for targeting the specific line.

The map widget in Slate fails to recognize the JSON string stored in an object property and throws the error message "Please enter valid json". How can this be fixed?

The problem can be solved by declaring a function in the Slate application that parses the JSON. For example, return {{object.property}}.map(str => JSON.parse(str)). The parsed value can then be used in the map widget.

How do I redirect to relative URLs in Slate?

A feature has been recently released where you can access the base URL via {{$global.window.origin}} and use it to construct your redirect URL. Alternatively, you can use JavaScript to dynamically get the base URL by running window.location.origin, and then construct your full URL for redirection. This can be done by creating a small invisible code sandbox that runs on Slate load and returns the value to a variable.

Will a query automatically rerun if the input changes?

Yes; by default, functions, queries, and widgets will re-run when their dependencies change. You can override this for the Queries using the configuration panel. An alternative method would be to trigger a re-calculation from an event, such as a button press. Use the events configuration panel in order to configure this.
