Jinja2: Add new key/value items inside a for loop statement - for-loop

Question

I want to append new key/value item to a hash inside a jinja2 for loop. Until now i have only been able to append a static entry, but i would like to add a test depending on the current element.
My data set looks like:
people:
- forename: John
name: Doe
gender: M
- forename: Jane
name: Doe
gender: F
I want to dump something like:
Hello Mr John Doe
Hello Ms Jane Doe
I can do something like :
{% for person in people -%}
Hello {{ 'Ms' if person.gender=='F' else 'Mr' }} {{ person.forename }} {{ person.name }}
{% endfor -%}
but i find this syntax awkward, especially if i have to repeat the test many times.
My idea is to add a title key to my data and i am trying to do it inside the for statement.
Jinja accept the combine filter for that:
{% for person in people | map ('combine', { "title": 'M.'} ) -%}
Hello {{ person.title ~ ' ' ~ person.forename ~ ' ' ~ person.name }}
{% endfor -%}
And i can also add a test to choose the correct title:
{% for person in people | map ('combine', { "title": 'Mr'} if 1==1 else { "title": 'Ms'}) -%}
Hello {{ person.title ~ ' ' ~ person.forename ~ ' ' ~ person.name }}
{% endfor -%}
But i have been unable to acces to the current person, i have tried thinks like person.gender=='M', self.gender=='M', this.gender=='M', but without success.
Is there any way to do it ?
Thanks !

Answer 1

I am answering my question since i finally have found a way to do it.
The key is to filter the people array with selectattr, then to apply the combine and do it again for the rest of the array.
{% for person in people | selectattr("gender", "equalto", "F") | map('combine', { 'title': 'Ms' }) +
people | selectattr("gender", "equalto", "M") | map('combine', { 'title': 'Mr' }) -%}
Hello {{ person.title }} {{ person.forename }} {{ person.name }}
{% endfor -%}
The for statement is of course more complex, but the loop body is straightforward.
