Hi all,
another update on the GeoGateway Django App. This week I've focused on state
management with Vuex and developing a modular and lightweight method for adding
KML map layers to the Leaflet map. I've opted to use Vuex to make communication
between child components easier. I've also removed Vue as a CDN (in favor of
Vue CLI + Webpack) and and fully separated the Vue frontend and Django backend.
The boilerplate code is significant but I now have a stable development
environment that can be deployed quickly.
A question I'm considering:
* What is the best way to implement file upload in an Airavata Django app.
Django has a relatively straight-forward method but it might not be the best in
our case
*
https://simpleisbetterthancomplex.com/tutorial/2016/08/01/how-to-upload-files-with-django.html
Generally, I'm wondering if this problem should be handled locally by the
application rather than communicating with Airavata.
Some things I've learned:
* If the application is going to have more than 10 Vue components,
implement a Vuex store from the start
* vue2-leaflet is not extensible enough for large GIS applications that
require customized map layers
* Webpack configuration can be painful and a boilerplate for future Django
+ Vue + Webpack applications will be helpful
Please reply with any comments or questions. Any recommendation regarding file
uploads would be appreciated. Thank you!

Subject: Project Update and Questions
Hi all,
This summer I am working on developing a GeoGateway Django app for the Airavata
Django Portal. So far I have developed a skeleton of the app and integrated
Vue.js for the frontend UI components. At this stage I'm looking for input on
some of the choices I've made and if any of them should be adjusted.
* Leaflet and Vue.js (over Google Maps and React.js)
* It seems at this scale that a modular app rather than Vue.js style SPA
makes more sense (although some of the other Airavata GIS applications are
mostly SPA)
There are a lot of style choices to be made and many I'm likely still unaware
of, so any tips on structuring and organizing a project like this will be
helpful.
I also have a couple questions I've accumulated about Django for anyone willing
to help:
* When working with a custom Django app in the Airavata Portal, should I
redefine the MEDIA_ROOT directory in the apps.py file? Is there a precedent for
changing variables like this defined in the project-wide settings.py file on a
per-app basis?
* I'm finding that {% include .....html %} works perfectly but {% extends
....html %} does not. I use the block/endblock syntax with unique names but the
content doesn't show up. Is there a reason I should use extends over include?
Thanks for reading.
