django-environ dictionary format

Question

I’m having a difficult time trying to understand how to write data to the .env file as to get a dictionary.

The docs say this:

dict (BAR=key=val;foo=1.1;baz=True) #environ.Env(BAR=(dict(value=unicode, 
cast=dict(foo=float,baz=bool)), {}))

In my .env file i have something like this

EMAIL=host=xx;port=xx;user=xx;pass=xx;tls=True

However, i really don’t know what to pass to the casting in the settings.py file

In casting up the .env file vars in settings file one need this structure for dictionaries for this particula case:

env = environ.Env(
      EMAIL=({
                'cast':{
                    'host':str,
                    'port':int,
                    'user':str,
                    'pass':str,
                    'tls':bool,
                }
               }, {})
    )

If an empty dictionary is supplied, then all the values will be cast as strings.

Two ways:

.env

DATA={"hello":"world"}

main.py

env = environ.Env()
environ.Env.read_env()

# Get the data

data = env.json("DATA")

type(data) # dict

.env

DATA=hello=world,hello2=world2

main.py

env = environ.Env()
environ.Env.read_env()

# Get the data

data = env.dict("DATA")

type(data) # dict

This works for me:

ENV:

# The value of the mockup user
AAA_MOCKUP_USER_OBJ={'is_authenticated'=True,'id'=888,'username'="sasha_test",'firstName'="Sasha",'lastName'="Rudan"}

common.py:

print(f"[common] AAA_MOCKUP_USER_OBJ={AAA_MOCKUP_USER_OBJ}")

printes well:

[common] AAA_MOCKUP_USER_OBJ={"{'is_authenticated'": 'True', "'id'": '888', "'username'": '"sasha_test"', "'firstName'": '"Sasha"', "'lastName'": '"Rudan"}'}
