Overview
The purpose of this lesson is explain the Actions in Wayfast. This “Actions” are events that allow us to interact with our Project DB. To make this connection, it’s mandatory to associate an action with a control. In previous tutorialslessons, we analyzed how to create controls and how they are connect to dataset. Actions will be connected to those entities when the application user has to interact with the interface. These actions are events that allow us to interact with our Project database. We can establish a connection between any action with a control.
Actions
Preconditions
We need to create a Dataset and Controls in our project’s page:
Inputbox: This control will allow us to insert data into our Project DB
Button: This control will trigger the insert and it should be connected to the Action that we are going to create
Grid_column: This control will display the values that we have stored into our Project DB
...
This is Let’s review the Page’s page’s structure in preview on the Application to verify how the application is depicted in developer environment.
...
Also a Stored Procedure is needed to save the input information in the frontend
...
.
See that the @Data1 and @Data2 are connected to the inputbox controls and the grid_column controls previously created in Wayfast. Once that the Stored Procedure is created, we can go back to Wayfast application and synchronize the SP Stored Procedure in the environment.
| Code Block | ||
|---|---|---|
| ||
CREATE PROCEDURE spHola_Mundo_AccionesTest_Insert
@Data1 nvarchar(50)
@Data2 nvarchar(50)
AS
BEGIN
INSERT Hola_Mundo_AccionesTest(Data1,Data2)
SELECT @Data1, @Data2
END
GO |
Click on “End Task” button related to Project’s requirement. This step is only needed for synchronization of the new Table and Stored Procedure generated in DB.
...
Now we have the new objects available in Wayfast Application to associate with Controls and Actions.
...
How to create new Action?
Return to Page’s information details.
...
Click on “Button” link and select “Actions” tab. Then click on “New Action” button to generate this new relation.
...
A new popup is displayed on screen.
...
Finally choose the instance (environment) where we are going to apply the Actions setting.
Click on “Accept” and the new action is created and connected to the Application.
If you want to check the new action under the application, let’s click on “Preview” button on the page and input new values. Then click on “Add” button which is the control associated to the action.
...
| Info |
|---|
We can verify in the DB that the table has the new input values inserted through the app. |
How to update Dataset with new Action created?
If the action created and linked to the control (button) is updating the DB but the new data is not displayed on screen in at the moment that we insertedwas logged, we need to check how the new action is connected to the Dataset.
Click on “Edit” icon related to Dataset dataset in Page’s detail.
...
A popup is displayed with dataset information. Turn to “Data Binding” tab
...
Focus on “Control run” field and search by the “Button” control that trigger the insert into our DB and database. Then click on “Add Relationship” button. This interaction will update the input data on page in real time.
...
Click on “Preview” button again on Page
Input new data and click on “Add” button. Every time that we click on the button, the Dataset will be executed and consequently, the information will be refreshed in the grid.
Recap
In the first part, we reinforced revised the preconditions to create pages with a basic structure (dataset and controls) and then we learnt about how to create new action items and how they actions that can be related to these Controls previously createdadded. In the second part, we verified how the interaction is executed in the application environment and how this can be edited to adjust the interaction regarding what we display and what we insert in the DBdatabase.
