Bonus Video: Intro to Leaflet

it would be awesome to expand this series with OpenStreetMap and Leaflet. Optional Mapbox, since there is a good free tier. I would love to see how a user could interact (with the map in the sense): * user can click on the map to store its position (i.e. for getting a delivery) * user can select a shop when clicking on a marker * shops can have a “delivery coverage” and users only select shops that delivers to his current location * delivery person gets route to follow (walking or by car)

This was a great tutorial. I really enjoyed the connection of the many different parts in this application: Postgres, Django, GeoDjango, Leafletjs. Plus the data source of overpass-turbo.eu was interesting and a great learning experience for me. I echo the comments of others to encourage more tutorials along this line. Thank you.

I ran into many problems setting up the virtual environment. I did a bunch of googleing to learn what a virtual environment is and how to change PATH variables, but then I discovered Anaconda. I was able to set up the virtual environment and complete the project using Anaconda. I think it was much easier while actually being more dynamic. I like QGIS, but they’ve changed their program downloads since you made this series, so you have to download the older QGIS editions for this process to work the way you have set up in the videos.

I really enjoied the series and learned a lot thank you!

ps one big issue with the venv that I ran into early on was using the command

“python venv myvenv”

and not

“python3 venv myvenv”

this is because in the video you display the former accross the screen, but then when you type in the video you use the latter. This took a long time for me to catch.

Thank you, that did what it said on the tin in terms of establishing the fundamentals of creating a Location based app with Django. I certainly enjoyed the style, detail and pace of the course. I feel confident that I can move forward from here in an informed manner.

My #1 takeaway - being introduced to overpass-turbo.eu What a great resource for grabbing geospatial data for my future projects!

Very pleased with myself for getting to the end and then the bonus of seeing an interactive map on the page :) Loved the way you explained the workings in some of the areas. Really helpful. Was hoping to see a bit more interaction with user input at the end but I guess that would make the course long - so maybe a part 2 for this would be nice.

Other thing I was wondering about is how you’d manage larger city files? I’m in Singapore so thought I’d download that but it warned me that it might be too big so I cancelled it. But how would you deal with that?

I had a couple of issues getting all the necessary components installed, especially the drivers - (for Windows). I even deleted everything and started again only to get the same error - then read comments from other students and found the answer. Best way to learn!

It would be nice to update this course with the latest versions available so the installation screens match and perhaps mention the different commands for different OS (where different).

Great project.

Thank you Jackie for this concious course. I echo with bultita’s third point. There are hundreds of tutorials in udemy or youtube for Django. But, it is difficult to find a good coures Django with GIS.

I think it would be very helpful to extend few more lectures on the models, how someone can enter longitutde, latitude data from Django admin, perhaps writing scripts to upload CSV/Json files with different sets of data.

Thank you for the great tutorial! I encountered just one issue on the final Leaflet portion:

        {% for shop in shops %}
            var circle = L.circle([{{ shop.location.y }}, {{ shop.location.x }}], {
                color: 'red',
                fillColor: '#f03',
                fillOpacity: 0.5,
                radius: 5
            }).addTo(map);
        {% endfor %}

My editor is expecting a js expression before the first ‘%’. Any suggestions? I’ve nested this within the same script tags as the map.

Hi @JoeFred is the code still working and is it just your editor complaining, or do you run into an error?

If it’s just an editor alert, then you can ignore it. It can be hard for an editor syntax highlighter (or linter) to figure out such nested languages. In this case it’ll have to understand HTML that contains Django templating language that contains JavaScript code, so that might just be too much for whatever plugin is trying to tackle it : )

If it’s not working as expected, can you describe in more detail what doesn’t work and what you see instead of the expected result?

VERY useful course!!!! Thank you! Is there any continuation on this topic??
