QUESTION
I have a React form for user login, everything works fine except for a setting a successful or unsuccessful message. Once i login, i set the value of a useState variable [res, setRes] to either successful or usuccessful depending on whether the user is registered or not. Problem is, even if the user is registered and username and password is correct, i get the message "invalid credentials" at least and most once. Subsequent calls from the same user result in the correct message being displayed. I searched and found that state is one step behind, and the solution is to use useEffect, but i am already using it. Can anyone help me figure out what the problem is? Code is as follows
ANSWER
Answered 2021-Jan-10 at 22:11The useEffect hook is always called when a component mounts, and after that every time a value in its dependency array changes. Since an empty object is presumably not a valid log in, you're always going to get an unsuccessful attempt when the component mounts. You could do some simple validation like:
QUESTION
I have a firestore with lessons, see the picture below, I get from the firestore the title property from each object and display it in the browser, but everytime I refresh the website the lessons are sorted by how they want, why is that happening? I want to sort them how I want, I want to start with 'Introduction' and so on, how can I do that? I think the orderBy() is not working here.
As you see in the image above, the order in the firestore is alphabetical, but in my page is sorted by its own, see the picture below.
I want the result to be by in a specific order, for example we have the following titles, these titles are from the firestore: "Display", "Introduction", "Alignment", my problem is that these 3 titles are in a new order every time I refresh the website, I want them to be: "Introduction", "Alignment", "Display". In my case I have more titles but this is what's happening, I don't know how to align them how I want or even alphabetical if is possible.
Below is the code that I used to get the data from firestore:
...ANSWER
Answered 2020-Nov-27 at 18:14If you use sort without any argument, it will sort array elements alphabetically. It looks like your array elements are arrays, which will end with unexpected behaviors. Use sort argument to ensure it uses your own sorting rules. For example:

QUESTION
I'm trying to accomplish something in React using hooks that I've done many times in Vue but can't seem to figure out how to do it. I want to have a function fire when a certain variable updates, however I want the function to involve other variables as well.
The code below is functionally the exact same, but my linter tells me the react version is wrong because the res hook should include input as a dependancy. What if I don't want the console to fire when input is changed, but only when res changes?
Thank you for any help!

Answered 2020-Feb-07 at 08:13Linter rules and React hook rules in particular exist to prevent common mistakes. If you believe the code is working as intended, a rule can be disabled:

QUESTION
I need to change the limits of widgets on a tkinter GUI and need to dynamically change them once the GUI is open and running.
For example, a scale widget's lower and upper limit needs to change once the GUI is running.
I have tried the various destroy() and forget() methods to delete the widget and replace the original one but I feel like this is not the best way to do it.
I have also tried just creating another instance of the widget in the hopes the original disappears but unsurprisingly this did not work either (I had to give it a go to find out what would happen).
Is there a better way of doing this that I'm missing or should I forget() said widget and create a new instance of the widget?

QUESTION
I´m pretty new in android. I have made communication between two Apps with BroadcastReceiver and intentServices . The thing is, I want to send information to the app2 from app1. In app1 I need to access a variable which is in MainActivity.class , I need to send it to servicev.class (the service where the intent is handled) but the variable "res" is null when I access it, why does that happen? (App2 calls app1 onHandleIntent and it breaks in res.getOtp() ) I try to create an extra setter getter class and also an intent but getIntent() does not work inside onHandleIntent... how can I achieve to pass res.getOTP (string) ? I really dont want to use SQLite
servicev:
...ANSWER
Answered 2018-Apr-16 at 19:19You are trying to instantiate a new MainActivity which is not the same as the running activity but a new instance.
If you need your IntentService to be able to get data from a running Activity you have options such as using SharedPreferences or SQLite. Instead of keeping the data in memory try to persist it in some database in the onCreate and then try to read it from the storage during handleIntent
