QUESTION
I am pretty confused what happens with my code.
The tool I wrote, accepts uploaded CSV files and parses some to get some data.
To have a init state for my useres I globally declared emptyUser with default values.
When I run my script and upload a file, emptyUser gets updated with data, which should never happen.
When I do not process any data, but output the emptyUser straight away, the object is empty as expected.
The 2nd thing is, that all users have the same data at the end, which is also the same data as in emptyUser
Could someone explain to me why the object gets filled even when I never change the content of it and why all users have the same content as well?
...ANSWER
Answered 2022-Apr-07 at 18:34Recall that in JavaScript, objects are passed by reference. Quoting MDN docs,
Objects are a reference type. Two distinct objects are never equal, even if they have the same properties.
Whenever you push an object to an array, you're actually pushing its reference and any changes to one of its properties will propagate to all occurrences of that object in the array.
In this case, the same emptyUser is being added to users array in some users[attacker] = emptyUser lines. The immediate fix is to instantiate a new object each time you use emptyUser. Luckily, with the spread syntax (...), you're able to perform a copy of all the properties onto the new reference.
It might be a better way of doing it in terms of refactoring, but changing all the occurrences of raw emptyUser to users[attacker] = {...emptyUser} should solve the problem right off the bat.
QUESTION
I created a typescript react component FormInput for my form. This component uses the MUI framework and react-hook-form. The problem is that I can't set the correct type in my component for param "control". I temporarily consolidated it with the use of type any.
Input type into props control is type Control.
In documentation react-hook-form is that param control?: Control | undefined
I think that the solution is to use generic.
This is my react input component:

Answered 2021-Dec-30 at 08:53I think the documentation is pretty clear that you have to use your form values as a type.
QUESTION
I use in Reactjs library material-table. I have for one column button for add image using dialog. It work good for add new row but if i want edit row after open dialog is closed edit of row. I think that problem can be cause with rerender.
After click at button is opened dialog for add image but edit of row is ended and i cant save change.
...ANSWER
Answered 2021-Nov-02 at 02:52You are correct, issue happen since you are trigger rerender on each state update, this happen when the columns provided to material table are static, but contain functions which update on every render, resetting the table state. Provide a stable function or column reference or an row id to prevent state loss.
So, you fix is:

QUESTION
I have created a page with some checkboxes and I want that the values of the checkboxes checked should be displayed in an array. the checkbox value should be removed if we uncheck the checkbox and added if it is checked. So far I have this code that gives only a single value in the array but I need all the checked values in one array.
...ANSWER
Answered 2021-Sep-30 at 15:26I tried to recreate the above code and found 2 possible solution. 2nd one where logic is handled in App.js is not recommended.
But you can use the 2nd option by creating state in App.js and handling the logic in another component.
I would suggest using redux when you have to use single state in more than 2 child componen.
- Logic handled in a separate component
App.js

I am quite new new Flask and Blobs in general, but I've been trying for some time to send a .wav file from my frontend to my backend. In general it seems like I should put the file into a FormData(), and send a post-request to the backend.
Here is my frontend code:

Answered 2020-Oct-24 at 10:20I finally found a solution. The problem was in the axios-request. I transformed it to a fetch-request, and then everything worked out. Here's the working request from the frontend:

I am not able to upload multiple files using Material UI dropzonze.
The API works fine with postman.
This is my console when I log the formData:

When I log files1.files, I get this:
ANSWER
Answered 2020-Aug-30 at 17:33I figured the solution out by appending the files as a value of formData function one by one with the same key (i.e. images) instead of sending the the array of images at once as a value with the key (i.e. images).
So essentially, I did this:

I've also looked at the documentation of the Material UI Dropzone, without any luck
...ANSWER
Answered 2020-Aug-06 at 15:54You can use DropzoneAreaBase which allows you to fine tune the component. You can control the files list via passing the files in the fileObjects array and updating in the onAdd/onDelete using your logic.
Note, you can play around with the snackbar to not show anything when an existing file was added, I'll leave this up to you.
