Fix map slider on location modal not updating on zoom

[nstjean]

Hi, this is a first-timers-only issue. This means we've worked to make it more legible to folks who either haven't contributed to our codebase before, or even folks who haven't contributed to open source before.

If that's you, we're interested in helping you take the first step and can answer questions and help you out as you do. Note that we're especially interested in contributions from people from groups underrepresented in free and open source software!

We know that the process of creating a pull request is the biggest barrier for new contributors. This issue is for you 💝

If you have contributed before, consider leaving this one for someone new, and looking through our general help wanted issues. Thanks!

🤔 What you will need to know.

Nothing. This issue is meant to welcome you to Open Source :) We are happy to walk you through the process.

📋 Step by Step

• 🙋 Claim this issue: Comment below. If someone else has claimed it, ask if they've opened a pull request already and if they're stuck -- maybe you can help them solve a problem or move it along!

• 📝 Update the file _form.html.erb in the plots2 repository (press the little pen Icon) and edit the line as shown below.

See this page for some help in taking your first steps!

Just after this code here:

plots2/app/views/locations/_form.html.erb

Lines 108 to 110 in fd5683d

	var slider = $('#ex1').slider()
	.on('slide', changeZoom)
	.data('slider');

Right after line 111 add this code:

      blurredLocation.map.on('zoomend', function() {
        let zoom = blurredLocation.map.getZoom();
        $('#ex1').slider('setValue', zoom);
      })

This will make the slider respond to when the map zooms in and out!

• 💾 Commit your changes

• 🔀 Start a Pull Request. There are two ways how you can start a pull request:

1. If you are familiar with the terminal or would like to learn it, here is a great tutorial on how to send a pull request using the terminal.

2. You can also edit files directly in your browser and open a pull request from there.

• 🏁 Done Ask in comments for a review :)

@nstjean Can I take up the issue if it has not been completed ?

[nstjean]

@DevchamploO Are you still working on this? Do you need any help?

I’m still working on this. I am work at the moment but will shoot for making a pull request this evening.

@DevchamploO Ok, great, thanks! Just wanted to check in! :)

I am having trouble running the app on my machine. When I run the passenger start command and navigate to localhost:3000 I receive an error that says ‘home/dev/repos/plots2/app/public/index.html’ is not found (2: no such file or directory) with a 404 error in chrome. It appears that it can not locate the correct path. I’m not sure why this is happening. I am using ubuntu 18.04 (wsl).

I'm not very familiar with install errors, I did a quick search and couldn't find anything that mentions that problem. I'm going to find someone who can help you with that!
In the meantime go through these instructions and make sure you didn't miss a step (because that happened to me when I installed everything!): https://github.com/publiclab/plots2#installation
You can also read through this thread for anything that might help: #3840

 I have not been able to resolve the issue I have been having. Everytime I try to run the server I get the same or similar error. I don’t think it is an installation error because when I add an index file it works fine. I have tried reinstalling but the issue persists. I think the problem lies somehow with PATH configuration. Since I am not sure when I can get this resolved I think that it is best to reopen the issue for someone else to work on it who is not experiencing these challenges.

@DevchamploO I'm sorry you're having problems! It does sound like a PATH issue. :(

After looking at the code for this page I believe I accidentally already completed this in #6957 where I was testing it. Oops!
