[feature request]: Integrate Custom Error Pages

[ashutoshkrris]

Is there an existing issue for this?

• I have searched the existing issues.

Describe the feature.

Our application should be able to serve custom error pages whenever it encounters an error.

Problem/Motivation.

Currently, whenever a user encounters an error, the default error pages are shown to the user, which is boring.

Possible Solution/Pitch.

Create view functions in the routes.py file to handle errors and serve custom error page templates.
You can take reference from here

Anything else?

This is a backend-related issue, and any beginner who has little knowledge of Flask can also resolve it.

Note: This issue requires custom error pages templates. There is another issue #37. Once that is resolved, this issue needs to be worked on.

Hi @ashutoshkrris! I have some knowledge of Flask. May I be assigned this issue? I'll do my best!

[ashutoshkrris]

Yeah, you can work.
But the problem is, the issue depends on issue #37

For the time being, what you can do is return any custom error page. Later when the issue #37 is resolved, we can change it.
Assigning it to you, @taanguyen

Thank you @ashutoshkrris! If I get stuck, is dropping a comment here the best way to reach you? Do you have a discord for this repo by chance?

[ashutoshkrris]

You can drop your queries here, or if you wish you can create a discussion

I believe I'm done! Thank you for the helpful reference link, Ashutosh! Commit is here. I'll wait for @rachelcynthia to make a pull request.

@taanguyen I have made a pull request. I linked the pages to custom error routes for the time being. That will have to be deleted later and replaced with routes you designed.

[ashutoshkrris]

@taanguyen I have merged the PR made by @rachelcynthia
So, you are good to go now.

[taanguyen]

thank you both!

@ashutoshkrris, I tried to recreate the 405 error, but when I send a POST to localhost:5000/ (instead of a GET), I get a 302 and then a GET / request is made which returns a 200. Is that the expected behavior?

[ashutoshkrris]

Remove the trailing slash at the end of the URL and try.
A POST request is valid on the index page, because it has a contact form.
You can try a POST request on the Terms of Service Page.

I see the change as index now accepts GET and POST- thank you!
