Commands

Create snippets of code that work across the Jetveo application. Allows for direct data manipulation inside application database.

Testing is also available. See Test in the upper right of the App Builder screen. See below for more information.

Creating a new a command​

General​

  • Name - name of a command, shown in a list of commands
  • Code identifier - code identifier of the command used internally and when logging application errors
  • Type - type of a Business command
    • Custom command - has it's own input model and it's own page that allows app user to fill it's model values
    • Entity command - a command executed on a specific entity record
    • Entity batch command - a command executed on a collection of entity records
    • Child entity command - a command that needs both entity and it's parent references
    • Child entity batch command - a command executed on a collection of entities that has a reference to parent entity
  • Result type - result of the command. Allows for creating Data grids or Documents from command results.

UI​

  • Default title for action button - default label used on a new Action button and on a Custom command page
  • Default icon for action button - default icon used in a label of a new Action button and on a Custom command page

Security​

  • Execution condition - security condition that needs to return true for the command to be executed

Custom Command Input Model​

Lets you set up a custom input Model for the command.

First, go to the "Model" tab and define Model's Attributes and References. You can use Inherited aspects. Attribute and reference values can be sent to a command through Parameters (that you set up when creating an Action button), or from command Page accessible to application user.

To set up such page, go to the "View" tab. As with any other view, select a layout and populate it with Data fields and/or Elements.

Using a command​

Business commands can be attached to different places or events depending on their type:

Entity commands:​

  • Entity pages (page Actions)
  • Entity page tab (page Actions)
  • List page (as a command or batch command)
  • Data grid (as a command or batch command)
  • Entity events (on created, on deleted, on attribute updated)

Child entity commands:​

  • Data grid (command, batch command)
  • Child Entity events (on child created, on child deleted, on child modified)

Custom commands:​

  • Entity pages (page Actions)
  • Entity page tab (page Actions)
  • List page (page Actions)
  • Application menu item (they have their own page)
  • API endpoint to allow 3rd party integration
  • Scheduled events

Command results​

Command results let you show or save result of a command.

Data grid result​

Custom command with a Data grid report result must return a new Data grid. It shows on a page that opens after the command execution and lets app users to save the result as .XLS file.

In the following example we create a Data grid that lists application users and their emails:

return new ReportResult(new ReportResult.Column[ ] { new ReportResult.Column("Name"), new ReportResult.Column("Email") },
        App.Security.Users.Select(u => new ReportResult.Row(u.Name, u.Email)));

Document result​

Custom command with Document result must return a new object of type DocumentResult.

In the following example, we use Razor + HTML template to render a new html page and then create a byte stream out of it to allow app users to save it:

    var htmlTable = App.Templates.HtmlReport.Render(templateModel);
    var tableBytes = Encoding.UTF8.GetBytes(htmlTable);

    return new DocumentResult("report.html", tableBytes);

Test Command Interface​

Commands can be tested directly inside the interface. This allows a code-run loop, with defined input values, where the user can edit on-the-fly for immediate results.

For example, the screenshot below shows code for a test email (left), the Configuration for a test to send the email (upper right), and the results (lower right).

Jetveo App Builder

The code needs to include the proper coding to define the logs that are to be generated. The instance and Model needs to be configured. Click “Run” to get the results.
