Hey everyone! Super happy with ServerSideComponents, but either I don't really get them or something is missing. I'm needed to hand over some values from the view to the component, so as suggested I used componentFromState. The problem is that I don't really want to fill the state but give it some props (like in React). So because I fill the state from the view, and I need to have a initialState my values would always be set to the initial state after an action handler executed. To not "loose" the state value that is filled from the view, I added it to the callServerAction like this:
<input data-gco2={tshow gCo2} class="range" type="range" min={tshow minValue} max={tshow maxValue} step={steps} value={inputValue value} oninput="callServerAction('SetCommonConsumptionValue', { newValue: parseFloat(this.value), newGCo2: parseFloat(this.dataset.gco2) })" />In this case I don't want gco2 to be reset so I add it to the callServerAction and after set it again in the action handler:
action state SetCommonConsumptionValue {newValue, newGCo2} = do
state
|> set #value newValue
|> set #gCo2 newGCo2
|> pureSo, do I use it wrong or should ServerSideComponents provide the possibility to hand over static values ("props" like in React)?
props style of initialization that you mention. I had success with the pattern shown in this digitallyinduced/ihp#936. It seems that this pattern works now, although I'm not working on that part of the app at the moment and haven't tested it so much since.At the time, I couldn't see this pattern mentioned in the documentation.
Hope this is helpful. As I said, I may be missing some context so be careful I don't send you on an incorrect path for your project.

hi, qq, is there a way to use custom newtype records as field types on database records ?
e.g. I want to have a newtype Money = Money { amount :: Double } type for a specific column.
Why? to give it special format, so it can render as $100,000,000 instead of 1.0e8

Hi everyone, how do I make dynamic meta data in the head of the html layout?
<head>
<title>Beef CO2 Footprint</title>
<meta property="og:title" content="Beef CO2 Footprint" />
<meta property="og:type" content="data" />
<meta property="og:description" content="The CO2 Footprint of beef is about 67kg CO2 per 1kg of beef." />
<meta property="og:url" content="https://domain.com/beef/" />
<meta property="og:image" content="https://domain.com/beef/image.jpg" />
</head>The title I got working with setTitle, but what about the rest?

Hello everone!
So, I have the following schema:
Table: Item
Columns: ItemID, Name
Table: Tag
Columns: TagID, Name
Table: ItemTag
Columns: ItemTagID, ItemID, TagIDFor the Index view of Items, I want to render each Item with its respective Tags.
Does IHP have an inbuilt fn (similar to collectionFetchRelated) which I can use here?

Hello everyone! So I'm switching from Bootstrap modals to IHP Modals in my codebase and I have this query:
I've a few modals which are being called from different views and based on where they are being called from, I want to set jumpToAction and modalCloseUrl dynamically so that the backdrop will have that respective view. What's the best possible way to achieve this?
The only approach I can think of is passing a variable in the action itself and use that accordingly..
