In Lawson v10, Admin users would have direct access to system logs but in the cloud, you’re access is limited to FTP access.

Problem: Reviewing IOS and LADB logs live is more difficult through FTP since you’re unable to download or view a file that is currently being written to. To get around this you simply use the copy line command or cp.

 

To understand this process, follow the steps below:

Step 1: Open LID and connect to the Lawson environment you want to access logs from.

 

Step 2: Go to %LAWDIR%\system directory

 

Step 3: Create a new folder in %LAWDIR%\system directory, command is: mkdir temp_logs (this will create a folder called temp_logs)

 

Step 4: In %LAWDIR%\system type this command (change based on your log names):

cp *ios_lsapp*.log temp_logs

 

Step 5: Go to %LAWDIR%\system\temp_logs and run the ls command to view your copied log files or simply download them from the FTP.

This node is used to parse a JSON response from a file or a web service call.  The input can be any JSON text, such as the result from a web service call or output from a file.

On the output tab, you can select a sample document that will help building the variable list.  When you click “Set Variable”, you can see all the variables that are available from the sample document, and you can export those variables so that they can be copy and pasted in assign nodes.

AWS has SES (Simple Email Service) which is used to help developers create notification emails. In order to use this feature, you must create a template for an email and then you can send emails. Currently, there is no way to create a template in the AWS console. One of the ways to create one is by using a Node script. You first need to have:

1. Node installed on your computer
2. An AWS account with access & secret keys
   

You will want to enter your account information where the red highlights are. Then you must add a template name (name you will be using when calling template), htmlPart (text in the email in html form), subject (the greetings), and text part (The email body that will be visible to recipients whose email clients do not display HTML).

 

Run the script and check if your template is in your AWS SES dashboard.

If you are writing code and you want a user to manipulate data using methods you create but also don’t want the user to be able to manipulate data directly. One way you can go about this is through functional programming. Say you want to have an object that has the ability to move right and left with a starting position at 0. You might build out something like this:

const walker = {
    position = 0,
    right: function() {
        this.position++
    },
    left: function() {
        this.position–
    }
}

Then you call the function, walker.right() to move right and walker.left() to move left. However the way this is set up, a person can redefine the position variable by just directly changing it I.e. walker.position = 20. This is not good because the walker will be teleporting without ever hitting positions 1-19. So how do you stop a user from directly changing a variable that you don’t want them to change. An easy way to make this a private variable, is to make a function that return an object with only the method you want them to use. For example:

function walker() {
    let position = 0,
    return {
        right: function() {
            this.position++
        },
        left: function() {
            this.position–
        }
    }
}

const ben = walker()
ben.right()

I made a new variable called “ben” from the walker function. The way this is set up a user can no longer directly change the position property.
