iBlog | 晚黎的个人博客，代码完全开源，喜欢就给个star吧！

I'm new with typescript, so I was creating a blog-app in which user can write blog(only text) with title and blog body. When, Add button is clicked blog should be added to blogs array and user should be redirected to Blogs page.

Problem: When Add button is clicked blog is added to array but user is not redirected.

Below is code:

Add.tsx

I built a blog web app a few months back. It worked correctly back then but, upon revisiting it now, the blogs will not load with a GET fetch request. I'm given an "internal server error" in Postman and "Uncaught TypeError: blogs.map is not a function" in my console.

I've updated npm and its dependencies, and resolved all errors marked in red in my code editor.

I've dug around SO and the internet, and it seems like the only solution I can find is "you're type'ing the fetched data as a 'string' when you need to type it as an 'Array' - but I've type'd mine correctly.

My code:

Home.tsx

I am working on a POC where I am trying to change the transaction log files in MySQL 8.0. From my findings, I think ib_logfile0 and ib_logfile1 are the files that I should be concerned with (Are there any other files that I should be considering ?). In order to do that, based on the instructions on this page, I am trying to do the following :

1. Stop mysql.sudo systemctl stop mysql
2. Add the line innodb_log_group_home_dir = "/media/newdisk/iblogs" in /etc/mysql/mysql.conf.d/mysqld.cnf
3. Start mysql. sudo systemctl start mysql

However, this did not seem to work. The start in Step 3 is failing. I have tried the following but none of these helped.

• a. restarted apparmor : sudo systemctl restart apparmor
• b. /media/newdisk is where I have the external disk. I created the iblogs directory and assigned RWX(777) permissions on it.
• c. sudo chown -R mysql:mysql /media/newdisk
• d. I have considered moving the ib_logfile0 and ib_logfile1 currently in /var/lib/mysql(default datadir) to /media/newdisk/iblogs

Should I also consider adding an alias in the apparmor cnf ? If yes, I dont quite get what should be my alias. Some examples I have taken a look at has the entire data directory pointing to the new location as a result of which they have set the alias for /var/lib/mysql to the new directory. But I am only concerned with the ib_logile*.

Tried the above approach using this solution ,but that did not work.

My function in views.py is:
