Macro challenge, something is not right in my code

Hello everybody.

As you may guess I am struggling with the macro challenge.

First of all here is my code:

{% macro hide_email(User) %}
  {% split_email = user.email.split('@') %}
  {% hidden_email = split_email[0][0] %}
  {% for letter in split_email[0][1:]: %}
    {% hidden_email += '*' %}
  {% endfor %}
  {{ hidden_email + '@' + split_email[1] }}
{% endmacro %}

I am pretty positive I am getting the right value for the user.email as I have tested the steps in the terminal but I am not able to pass the code challenge.

I am not 100% sure but I think it has to be something in the connection between files: what I mean by this is if I need to change something else in the other file or maybe using wrong names in my code.

I have watched the video a few times now but unfortunately since we do not have access to the user.html file I can't really figure out where I am going wrong here.

Any idea / hints ?

Much appreciated Ty

Vittorio

lunch.py 
from flask import Flask, render_template

app = Flask(__name__)

@app.route('/')
def index():
    class User:
        email = None
    user = User()
    user.email = 'kenneth@teamtreehouse.com'
    return render_template('user.html', user=user)
templates/macro.html 
{% macro hide_email(User) %}
  {% split_email = user.email.split('@') %}
  {% hidden_email = split_email[0][0] %}
  {% for letter in split_email[0][1:]: %}
    {% hidden_email += '*' %}
  {% endfor %}
  {{ hidden_email + '@' + split_email[1] }}
{% endmacro %}

Hi Vittorio,

I assume you are dealing with the Macros challenge:

http://teamtreehouse.com/library/build-a-social-network-with-flask/takin-names/macro

..and are trying to find out what code you need to put in the "templates/macro.html" tab.

Have you looked at this other forum thread dealing with the same challenge:

https://teamtreehouse.com/forum/create-a-macro-hideemail

I found Dan Johnson's answer code (which uses 'set' to bypass the need to use a for...endfor loop) to be especially helpful:

{% macro hide_email(user) %}
{%- set handle, domain = user.email.split("@") -%}
{%- set hidden = handle[0] + ("*" * handle[1:]|length) -%}
{{ hidden + "@" + domain }}
{%- endmacro %}

Hello James.

Ty for your reply.

Yes I am dealing with that challenge and I have seen the other 2 threads related to it.

I pretty much understand those, but I can't figure out what I did wrong as I think my code delivers the same output...

The code challenge does not accept it as good, so I went wrong somewhere and would like to understand where.

;)

The challenge has been updated to show the macro output in the preview pane. Hopefully that'll help you see what's going on.

Thanks Kenneth.

That helps out a lot in understanding that the syntax changes in jinja2.

At least this is what I understood.

Well done, I think you deserve more than 7000 points

:-D
