QUESTION
I am following Colt Steele's React course. Sadly, the course is outdated so I chose to migrate to the latest versions of libraries myself.
Coming to the point, I am now facing this error where I am not able to extract URL params using the useParams hook in my functional component. I am pasting my code below for the community to check.
App.js
...ANSWER
Answered 2022-Feb-08 at 20:54The useParams
hook can only access the route match params of a Route
within the context of the Routes
component rendering it. App
is outside the Routes
component that renders a route rendering path='/palette/:id'
.
You can create a wrapper component to "sip" the id
route match param and do the filtering.
QUESTION
After entering the color name in the input field, when I submit the form, an error occurs :
TypeError: Cannot read property 'toLowerCase' of undefined (anonymous function) C:/Users/HP/Documents/WDB/React/Practice/colors-app/src/NewPaletteForm.js:117
...ANSWER
Answered 2021-Aug-12 at 06:18What you can do is check to see if the value
exists before calling toLowerCase.
Try using ?.
, like this
Instead of using value.toLowerCase()
use value?.toLowerCase()
.
That way if the value
is undefined or null, it won't call toLowerCase()
If paletteName
is the one failing you can use paletteName?.toLowerCase()
If you want to go completely safe you do

Install flat-ui
You can use flat-ui like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
