Do not allow to save links with an empty title

[danilax86]

When it was possible to do so, a link looked super weird in a list view and you were not able to click on a link and visit one.

Here is a screenshot:

So, I decided to make a custom rule for garde. Now it looks like this:

A better feature may become to create a somewhat title fetcher, when title is empty. A client sends get request and parses response body by looking for <title> tag, if there is none, finds a <h1> and so on. If nothing else found a message returned and users are asked to provide a title themselves.

Thanks! Automatically fetching the title is already being worked on in #63.

Could you run cargo fmt to format your changes?

[danilax86]

@raffomania done

upd: made cargo fmt, empty line was added, force pushed, but nothing changed in github when looking at a diff. Strange..

[raffomania]

I can see the change in the diff - do you have the "hide whitespace changes" setting on?

[raffomania]

The lints are still failing - please run just lint (or cargo clippy -- -D warnings) to see the errors and instructions on how to fix them.

Tip: You can run just ci-dev to catch almost all errors that would make the CI fail, locally, before pushing :)

@raffomania Thank you for tips!

I couldn't beat garde's impossibility to create a custom rule without context. I mean, I did with providing an empty context, but linter was suggesting do not pass context by reference, but by value, which breaks fn(&T, &<T as Validate>::Context) -> garde::Result as being said: https://github.com/jprochazk/garde?tab=readme-ov-file#custom-validation

I found a solution with garde's required rule. Changed type of title to Option<String> and dug around templates a bit. Have a look: danilax86@ae4d40b

Tell me, please, which solution do you like most

[raffomania]

Great initiative! Using an option is a creative solution. I think the custom validator is more straightforward and easier to understand. Bypassing the clippy lint is totally justified here. Thanks for your contribution!
