    Mapping is coming along nicely. Today I got markers to move by clicking the map, serializing changes to geo-json for saving, and integrated leaflet-geosearch. 

    Next I'd like to automatically fill in the address when available, but in order to do so, I must first normalize the Nominatim addressdetail response to match up with my fields.

    A look at moving and searching for locations

     After making it so I can update my location for an entry, I started to integrate Leaflet, rather than use the default GeoDjango OSM widget. It's my first time working with Leaflet, so it's a bit slow going.

    I've managed to get basic display of the map working as well as clicking to move the point. I think if I can get the point to be powered by some GeoJSON in a hidden textarea, I should be able to once again set and update locations on entries.

    Leaflet in Tanzawa

  • The Week #35

    by


    • The biggest thing to happen this week was Leo graduating from from the "higkari-gumi" at his pre-pre-school. I couldn't attend, but saw a small video. He was so proud of himself. He got a cool medal, a hat, and a certificate that we've framed. He starts pre-school full-time at the same school next month – he's so ready for it. My only concern is keeping his english ability when he's playing in Japanese all day. His output in English is already "behind" that of his Japanese (as expected, since we live in Japan) – I just hope it just doesn't regress.

    • We're finally back down to double-digit covid cases in Kanagawa again. We haven't been in this range since probably November or December. We're not out of the woods yet, but starting to see light at the end of the tunnel. If only they could speed up the vaccinations here, they're off to a snail pace.

    • In my entire life I've owned 3 suits. 2 suits I got when I first graduated from the Men's Warehouse and became way too big for me once I moved to Japan ( it's common for people to lose weight when they move to Japan because a combination of smaller portion sizes and taking trains/buses everywhere instead of driving). Those 2 suits fell apart almost immediately. The other suit I got as a replacement for my sister-in-law's wedding 11 or 12 years ago. The white shirt I bought with it was getting pretty gross so I went out and replaced them this week. I don't think I've ever owned this many dress shirts at a single time. Now I just need an occasion to wear them. (Even as a salaryman, I never wear a suit - even when going in to the office (which I haven't for over a year)).

    • I'm starting to blog (even more) with Tanzawa. As it gets more feature complete it's easier for me to blog with it than it is Wordpress.

    • Around a month ago I bought tanzawa.blog. It will be the home of the Tanzawa project (maybe hosting???) once it's ready for release general consumption. In the mean time, I've redirected tanzawa.blog to tanzawa.jamesvandyne.com

    I got locations saving to notes properly. Next up allowing you to update locations when editing an entry. When saving I initially ran into the following error:

    spatalite no such function: lwgeom_version

    The issue was that Django's PointField default projection is 4326, which is used for spherical references e.g. Google Earth. However, I'm displaying a flat service (an OSM Map), which uses a different projection 3857.  I fixed this by changing my database to match my most common display.

    from django.contrib.gis.db import models as geo_models
...
point = geo_models.PointField(geography=True, srid=3857)

    First steps in displaying location in the Tanzawa admin interface. Default point is Mount Tonodake in the Tanzawa mountain range. Still using the default OSM map included with GeoDjango.

    I imagine this will be a Leaflet powered map in the end. I've got a couple of different ideas surrounding the location interface:

    1. 1. I'm probably not going to display the full address form and instead have a single unified search form + map when no location is set.
    2. 2. Once an address is set, I may show it in plain text below the map. Perhaps there with an "edit" link to manually override the address for whatever reason.
    3. 3. I'll probably do an initial release as-is (using OSM) and then focus one of my later sprints on really polishing the mapping interface.
