CRDS Submission tool for INS scientists
This site uses Django, a Python package for web development. Django has a bit of a learning curve, and some of the tutorials just dive in without giving you the Big Picture of what the package is doing for you. One of the best explanations I've seen is in the Mozilla Django tutorial, especially this section: What does Django code look like?. Otherwise, I used tutorials by Corey Schafer, of which this is the first.
To use the code, clone this repository and then, from the top-level directory of the project (in which there should be a file named manage.py), type
% python manage.py runserver
This will start a simple server that is used to serve up the Django page.
In your browser, enter the URL http://127.0.0.1:8000/submit_reference_file/
This gets handled by the file ins_submit/urls.py in the first line of urlpatterns:
path('submit_reference_file/', include('submit_reference_file.urls')),
This delegates the URL of the SITE (ins_submit) to the APPLICATION (submit_reference_file).
We can look in the file ins_submit/submit_reference_file/urls.py to see that the path with an empty string in the submit_reference_file application is handled by the entry 'index' in views.py:
from django.shortcuts import render
from django.http import HttpResponse
from django.template import loader
# Create your views here.
def index(request):
template = loader.get_template('submit_reference_file/index.html')
return HttpResponse(template.render({}, request))
This delegates the work of displaying the page to a template. This is stored in
ins_submit/submit_reference_file/templates/submit_reference_file/index.html
This is the file that actually contains the html that gets rendered when we load this page.
The file index.html was created by hand modeled extensively on the file
crds-server/sources/interactive/templates/batch_submit_reference_input.html
and doesn't actually do anything, but potentialy the items in double braces can get passed to a handler routine that will live in the submit_reference_file/models.py file.
