Constants values and best practices

Good day! 
How are you? 
I have the following situation: 

In more than one django project I come across the situation where I need to define a model that has a State.
So what I usually do is: 

# Pseudo code here 

def State (models.Model): 
     name = models.CharField () 

def Purchase (models.Model): 
     # Fields various (name, descrption, etc) 
     State = models.ForgeinKey (State) 
     # More fields ... 
    
The problem arises when I want to do things like: 

if (Purchase.State_id == 1): 

    # Do stuff 


my way to fix it so far was to define a const.py and do something like: 

if (== Purchase.State_id Const.STATE_EGGS): 

    # Do stuff 

Because the state 1 is "eggs", but because I add in my local, but if another dev adds in staging, as that uniformity is maintained? 
It should create a process that creates the updates as new constants was defined? 
There are best practices for this? 

Ideas? Advice? 

Thank you very much for reading =) 

regards, 
Julian.
