TemperatureView | TemperatureView : 自定义 View ，用来显示温度的变化

I'm new to asking on StackOverflow and to Django so I'm sorry if I made any mistakes.

So far, I have a basic API with Django and REST Framework. I want to return just the last object that was added to the database, which could be done with the highest ID.

This is the models.py:

When I make a call to the DarkSky API, for certain locations, my onResponse and onFailure methods are not triggered. I've tested tons of locations in the US, and everything is fine. I tested London, and that was fine, but when I test Chennai, India, neither method is triggered. I also tested the URL being called and there is a response when I put it into a web browser, but it's not triggering the onReponse() method in the app.

I've seen some people say it's because the call is asynchronous, but I don't know why it would work with 100% consistency for certain cities but not others.

Calling class:

Description:

I have an view that is called every second to display temperature data to temperature.html from the backend of my project. In order for it to fulfill its purpose it needs an variable which will be passed through render to the template, where i want it to be used as an Javascript variable in order to update the canvas-gauge that I am using within the template to display temperature data.

Problem: My view is being called through the console at the correct interval, so that is not the issue. However, what is not happening is the variable is not being passed through to the template at all. I have tried to have the template display the variable to see if the variable is at least being sent to the template. Answer: It is not reaching the template at all, variable outputs "undefined". I have passed forms in this manner through my other views in the same way I am attempting to pass this variable, and it works correctly. I do not understand where I am mistaken with my template/view. I have researched for at least 6 hours in attempt to find the solution and clearly I have not found an solution relevant to what I need. From what I've read it seems the way I am passing my variable is correct. However, I am relatively new to Django, so there are components to the matter that I don't quite understand yet.

I'm trying to retrieve certain JSON data from a webserver, which I want to use to display a certain value in an android app. The request is successful (as in, the data is retrieved from the server), but when I want to actually use the JSON, I get the error org.json.JSONObject cannot be converted to JSONArray. The JSON retrieved has the following structure:
