UndefinedError in jinja condition

{% if user.photo is defined %} 
{{ user.photo }}
{% else %}
#gravatar
{% endif %}

I am trying this code, but I am getting UndefinedError: 'user' is undefined in first line.

Everything works fine if i use this:

{% if user is defined %} 
{{ user.photo }}
{% else %}
#gravatar
{% endif %}

What is wrong with my first code?

Your user object isn't set, so test if both are present:

{% if user and user.photo %} 
    {{ user.photo }}
{% else %}
    #gravatar
{% endif %}

Just testing for boolean truthfulness should be enough.
