Jinja templates not working in superset 1.0 rc1

Queries using Jinja variables are not working anymore in Superset 1.0 rc1.

For instance I have a dataset defined as follows :

{% set title_target = ' "'  + filter_values("title_target", 'Joker')[0] + '" ' %}
{% set title_type =  'title' %}

{% if filter_values('title_target_original')|length > 0 %}
    {% set title_target =  ' "'  + filter_values("title_target_original", 'Joker')[0] + '" ' %}
    {% set title_type =  'title_original' %}
{% endif %}


SELECT {{title_target}} AS title_to_display

I use to work well but now I receive the following error:

Error: (1064, 'You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near \'%\n set title_target = \' "\' + filter_values("title_target", \'Joker\')[0] + \'" \' \' at line 4')

If I move the Jinja parameters in the “template parameters” section:

I receive the following error: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)

@lilila I’m not able to reproduce the first case - I assume you’ve enabled the template processing feature flag?

FEATURE_FLAGS = {
    "ENABLE_TEMPLATE_PROCESSING": True,
}

See #11172

I think the correct place with docker nowadays is here:
