Angular in Dashboard - repeating buttons

[hazymat]

I have this template node, where the table rows repeat with the number of parameters in msg.Notify.

I'd also like to include a button for each row, that simply sends a message out that can be used to update the object in context, or whatever.

I've studied @TotallyInformation's excellent primer but can't quite work out how to do it.

<h1>Notification List</h1>
<table>
<tr style="font-weight:800;"><td>ID</td><td>Start</td><td>Title</td><td>Text</td></tr>
<tr ng-repeat="(key, value) in msg.Notify">
    <td>{{key}}</td>
    <td>{{value.Starttime}}</td>
    <td>{{value.Title}}</td>
    <td>{{value.Message}}</td>
</tr>
</table>

[TotallyInformation]

Are you able to share some data? With the example you've given, msg.notify would need to be an object:

msg.notify = { 
    key1: { Starttime: ....., Title: ......, Message: ..... },
    key2: { ..... }
}

[hazymat]

Hi, yes it is.

I have loaded it from global context into the message object, and here's what the message object looks like (debug from the output):

{"_msgid":"cee7f04b.6a931","topic":"","payload":1569872000671,"Notify":{"RearPumpFail":{"Title":"REAR SUMP ALARM","Message":"The rear sump says it's flooding","Priority":5,"Recipient":[],"Validity":"Start","ID":"RearPumpFail","Acknowledged":false}}}

The display of existing data in rows works, but I'd just like to work out how to post data out using a button for each row

[TotallyInformation]

Ah, I must be tired as I completely skipped over the button part!

Something like:

<button ng-click="node.send({payload:'plink', topic: key})">
    Send
</button>

within the tr tags?

I rarely use Anglular these days.

@TotallyInformation

Send

Ahh, I didn't realise you could insert node.send like that.

I've tried it though, and unticked the option in template node to "pass messages through" (so I don't get stuff that is sent to the input of the template) but nothing comes out when I click it. Any ideas? Thanks

[TotallyInformation]

I didn't remember the syntax correctly. Actually the answer is in my article:

<md-button ng-click="send({payload: 'Hello World'})">
    Click me to send a hello world
</md-button>

[hazymat]

@TotallyInformation

Click me to send a hello world

That works, thanks so much. Also thank you for that article you wrote. Over the last 3 months I have returned to view a number of times (although clearly most of it hasn't sunk in to my brain yet!)

Really looking forward to getting in to uibuilder, once I can get my head around it

Any idea how I would go about getting the output to relate to the row in question?

e.g. something like

<td><md-button ng-click="send({payload: '{{key}}=hello'})">Ack</md-button></td></tr>

(my addition of {{key}} results in getting this output:
payload: "{{key}}=hello"

as opposed to
payload: "RearSumpFail=hello" (or whatever the key in question was)

EDIT: just worked that out. I inserted key without the moustache syntax like so:

<td><md-button ng-click="send({payload: key+'=hello'})">Ack</md-button></td></tr>

@hazymat

thank you for that article you wrote

No problem, glad it has helped. I often write those because I know that I won't remember next time I need to do something.

Just install it, add a node to a flow with an inject and a debug - the "vue" example even does that for you, use the examples section of the import menu. Then open the resulting page. Then work step-by-step through the front-end javascript - it is nowhere near as complex as it looks.

Or try this nice little example:

Which produces a really simple page that shows a quote taken from a quote API. I must remember to put this into the examples for the next release.

It really is amazing what you can build really simply with VueJS and bootstrap-vue:

Ohh my, @TotallyInformation this is beautiful, could you point us to any code stubs that we can get a fast start - specially on the buttons?

[TotallyInformation]

Hi. The node's WIKI page contains loads of examples, there are also some in the flows library.

The buttons are bog-standard bootstrap-vue, you can change the colour dynamically, in the image, I use green and amber which are both standard colours in bootstrap. The flame icon is an SVG version of a Font Awesome icon if I remember correctly, you can download that from their website. The nav header and tab bar are all standard bootstrap-vue.

All very easy to do thanks to VueJS and bootstrap-vue - and Node-RED of course

Thank you
