Re: Why I can't pass anything to my html? Django 2.1
The content for the `render` method is supposed to be a
dictionary:
https://docs.djangoproject.com/en/2.1/topics/http/shortcuts/#optional-arguments
So change it to this render(requset, "FrounterWeb/body.html",{'tank': tank})
Also in the template file you want to display the properties of the ORM
(tank_system) object I guess, change them to {{tank.EC}},
{{tank. temp}}, respectively.
Hope it helps!

Re: Passing values from Python to Javascript
It is going to be like following.
In HTML (doesn't have to be div of course any HTML tag can get data
attribute:
...
Then in JS:
var dataElement = document.getElementById('backend-to-js-name');
var name = dataElement.dataset.name;
console.log(name);
Check it out "data" attributes
here:
https://developer.mozilla.org/en-US/docs/Learn/HTML/Howto/Use_data_attributes

Re: Passing values from Python to Javascript
As you can guess this is general problem for all backend languages for
passing data to JS.
AFAIK the standard practice is attaching the value to a DOM element as
"data" property and using fetching the value from that element in your JS.
If it is a primitive value it is easy to do so, if it is relatively complex
structure, e.g. dictionary of classes etc. you can create a string
representation of it (maybe in JSON format) and pass it to the template.
Check out this link's method #4, it is on .NET but the idea is the
same:
https://blog.mariusschulz.com/2014/02/05/passing-net-server-side-data-to-javascript.
Hope it helps!

Re: First Django app tutorial
It will be a bit generic help: To understand what's going wrong with your
code when you expect other type of behavior you can use debugging tools
like: pdb or (if you use an IDE like pycharm) build-in IDE debugger
(https://www.jetbrains.com/help/pycharm/debugging-django-templates.html,
https://www.jetbrains.com/help/pycharm/debugging-django-templates.html).
I believe you'll get to the root cause of the problem faster with debugger
use.
