QUESTION
I'm trying to build a website for tv series using Django framework, I put in the models.py all kinds of details about that show and a JSONField to define the number seasons and episodes in each season.
Example: { "s1" : 15 , "s2" : 25 , "s3" : 23}
I made a dropdown in the template where the series is playing so the user can select the episode
the problem starts when I try to access the values of the keys in the JSON object passed.
I tried that:

I want to save a model instance with JSON dict with integer keys, like {2: 3}.
But after saving my dict turns into {"2": 3}. Is there any way to save integer keys into JSON?
ANSWER

{2: 3}.
That is not possible: the JSON specifications say that keys are always strings. The JSON serializer in Python will convert the keys to their string counterparts (perhaps it was more appropriate to raise an error in that case).
If all keys are integers, you could make a subclass of a JSONField that will automatically cast the keys to ints, for example:

Install jsonfield
You can use jsonfield like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
