Print all properties of an App Engine Model

I\'m trying to find a way to easily loop through a Google App Engine (Python) Model and to print out each property and the property name.

I'm trying to find a way to easily loop through a Google App Engine (Python) Model and to print out each property and the property name.

This is how I'm trying it, and after some research I realize I can't next variables in each other. Is there a way to do this with filters or a way to return all of the values of the properties of a Model?

Thanks

templateargs = {'properties':MyModel.properties(), 'user1':MyModelObj, 'use开发者_C百科r2':MyModelObj}


{% for property in properties %}
    Property: {{property}}
    User1:  {{user1.{{property}}}}
    User2:  {{user2.{{property}}}}
{% endfor %}


Take a look at how this to_json method grabs all the property values on a Model instance, it should point you in the right direction.


After some more research I realized the proper way to do this was with gettattr. I used a filter along the lines of:

@register.filter 
def mygetattr(obj, name): 
    return getattr(obj, name) 

As suggested here


Try:

vars(user1)[property]

See Built-in Functions.html#vars for a short explanation of how vars returns a dictionary of the instance variables.
