Comments about the new Array List component

[luxray]

Great new feature! This was always a headache for me

[George]

Well if you haven’t add any items to it or assigned a value it will be empty of course

[Notum]

Looks like contains doesn’t work:

[Teodor]

Contains looks for direct values, not properties of objects.

[Notum]

Could you please explain a bit more?
Or give some examples?

[Teodor]

Arrays can contain strings list:

{
    "myarray": [
        "San Francisco",
        "Boston",
        "Amsterdam",
        "Paris",
        "Tokyo"    
    ]
}

or objects:

"myarray": [
    {
        "city": "San Francisco"
    },
    {
        "city": "Boston"
    },
    {
        "city": "Amsterdam"
    },
    {
        "city": "Paris"
    },
    {
        "city": "Tokyo"
    }
]

So ["San Francisco","Boston","Amsterdam","Paris","Tokyo"] (first example) contains Paris

But [{"city":"San Francisco"},{"city":"Boston"},{"city":"Amsterdam"},{"city":"Paris"},{"city":"Tokyo"}] does not.

There is already a formatter for this. Why create a module?

[aschoijett]

1. I’m really looking forward to trying this new functionality! As said before, a much needed addition.

2. As @sid said, all this s/b documented fully. I’d like to add “and ideally, not in the forum”.

3. A really minor suggestion: to avoid redundancy, call the component only by the word “array” (or list, if you prefer). No need to call it “array list”.

Think of an invoice embedded in an email.

In other words, something that we have been asking for since the birth of Wappler.

[sid]

Oh no, I am just talking about the array list contains module.
The complete set of modules is actually great and very useful.

@aschoijett

and ideally, not in the forum

@ben

Think of an invoice embedded in an email.

I haven’t tried the new feature yet, but I have no doubt it will be very useful. However, I wouldn’t expect it to make it easier to embed an invoice in an email. Would it be very different to putting line items + some HTML into a variable, using a repeat, and incorporating the variable into the email?

[Teodor]

Actually a lot easier and cleaner than using repeats, variables with global names etc.

Working with Server Connect Array Lists

Intro The Server Connect Array List component allows you create and manipulate Array Lists easily with Server Connect actions. You can add items to an array, join multiple sources, remove and set arbitrary items, keep simple or complex objects or collections in an Array List. It’s also easy to use it as a string builder, when you need multi lines strings. Basics In order to be able to add items to an array you first need to define the array. The Array List actions are located in the Data Man…

@Sid: found it, thanks.

[Heather_Mann]

Very exciting update. Thanks guys!!

[aschoijett]

Quick question:
Is there a reason for the steps under Data Transformation (Add Columns, Rename Columns, Filter Columns, Join, which too seem to be related to arrays), to be placed in a different folder as the 14 components announced with the 5.3.3 release?

I found that you can access the posting from the DOCS link Wappler Documentation - Working with Server Connect Array Lists

the images do not show properly. See an excerpt here:

This does not happen if I access it from the FORUM using this link:

Fixed.

The screenshots seem to have become ‘unfixed’.
