React - Each child in a list should have a unique “key” prop

Asked 2021-Jun-16 at 03:48

I am working on a React Web Application Where I fetch and display student data from an API and I keep getting the error,

Warning: Each child in a list should have a unique "key" prop. Check the render method of Accordion

Accordion.js being one of my components of my Web Application

Any Help to fix this issue would be appreciated :)

I have tried passing a key prop with an id to the Accordion component from a parent component, but that did not seem to work. Could it be that I need to pass a key in my test score paragraph?

You have included fetching function in the component as it is, so it fires every time component being rendered. You better to include fetching data in useEffect hook just like this:

My chainlink request isn't getting fulfilled?

Asked 2021-Jun-16 at 00:09

Can someone help me investigate why my Chainlink requests aren't getting fulfilled. They get fulfilled in my tests (see hardhat test etherscan events(https://kovan.etherscan.io/address/0x8Ae71A5a6c73dc87e0B9Da426c1b3B145a6F0d12#events). But they don't get fulfilled when I make them from my react app (see react app contract's etherscan events https://kovan.etherscan.io/address/0x6da2256a13fd36a884eb14185e756e89ffa695f8#events).

Same contracts (different addresses), same function call.

Here's the code I use to call them in my tests

Remove your agreement vars in MinimalClone.sol, and either have the user input them as args in your init() method or hardcode them into the request like this:

Firebase calls like this are asynchronous, meaning they don't return immediately. In Javascript, you can deal with this in a couple of different ways, using async/await or Promises.

Here's an example using a Promise:

How to make an axios get request on page load, then render a am4chart with that data?

Asked 2021-Jun-15 at 22:40

I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.

I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.

Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.

QUESTION

React Native - Justify Content not Working

Asked 2021-Jun-15 at 21:59

I've been struggling with this all over my react-native app, so I set up a very simple example of it in codesandbox which you can view here:

https://codesandbox.io/s/elastic-star-5754q?file=/src/App.js

Within the View with the green background, all of the internal views are centered horizontally within their respective spaces as I would expect thanks to the "alignItems: center" style property. I would expect that I could also center them vertically within their spaces by setting "justifyContent: center", but that doesn't seem to work for me.

Am I fundamentally misunderstanding something?

...

ANSWER

Answered 2021-Jun-15 at 21:59

The problem is that you are not aligning the text within the individual Views. Your example mistakenly aligns the inner View elements within the larger View element rather than aligning the text.

To center-align the text vertically within their Views you just need to add justifyContent: "center" to those individual three green Views.

Here's an example: https://codesandbox.io/s/recursing-kirch-n8one?file=/src/App.js:393-417

To further explain why you were experiencing the issue you did, see this screenshot with boxes outlining the space the elements were taking up on-screen:

You can see the inner Views are only taking up the needed width of the text elements inside, but are using the max height available to them.

ANSWER

Answered 2021-Jun-15 at 20:51

You seem to be confusing useState with the class component's state.

Running setState({ testInfo: testInfoArray }); sets the entire state to { testInfo: testInfoArray }, removing state.selectedParagraph entirely, causing it to be undefined.

You'll want to use useState multiple times, like this:

From what it looks like, options is actually an array of objects rather than just an object. So all you would need to do is map over the options variable. You are currently using Object.keys which is what you use if you are wanting to iterate over the keys in an object.

QUESTION

keep the data in app even when i navigate to other pages and back

Asked 2021-Jun-15 at 20:35

I'm using React and Next.js with Firestore. On one page I get data from Firebase with useEffect only once the page is rendered. But since the get is kind of costly (lots of read), I want to persist the data fetched even when the user navigates to other pages and back to this page, so that I don't need to fetch again. How can I do that? Thanks!

...

ANSWER

Answered 2021-Jun-15 at 19:03

There are multiple ways but one good way would be to use Context, create a data store context which would store your data and then you can read from it as a single source of truth.
