there is my sls file:
{% set java_script_path = salt['pillar.get']('script_path', default='/opt/java-app') %}
{% if salt['pillar.get']('script_path') %}
{% set file = {{ java_script_path }}/startup.sh %} ## seem this line have Jinja syntax error
{% if salt['file.file_exists']('{{ file }}') %}
cmd.run:
- name: mv {{ java_script_path }}/startup.sh {{ java_script_path }}/startup.sh.backup-$(date +"%Y-%m-%d-%H-%M-%S")
{% endif %}
{% endif %}
is using salt['pillar.get']('script_path') can not split other string?
example: name: {{ salt['pillar.get']('script_path') }}/startup.sh will raise error like: failed: Jinja syntax error: expected token ':', got '}' how can i fix ?
can you help me to fix my sls file to work?
{% already starts a Jinja context. You do not need to try to start another one with {{.
{% set file = java_script_path ~ "/startup.sh" %}
It was expecting a : because { starts a dict literal.
In simple use case such as shown in your question, you might not even need to set another variable at all. We could directly use {{ java_script_path }}/startup.sh in the if condition. Like below:
{% if salt['file.file_exists']("{{ java_script_path }}/startup.sh") %}
cmd.run:
- name: mv {{ java_script_path }}/startup.sh {{ java_script_path }}/startup.sh.backup-$(date +"%Y-%m-%d-%H-%M-%S")
{% endif %}
You could also reconsider using command to backup the file, and use an appropriate Saltstack module instead.

I have a use case where I would like to define the name of a macro and then apply it to one column.
A simplified example could be as follows. I have two macros defined that I want to call dynamically in my model (both take one column as an input):
cast_to_string
convert_empty_string_to_null_value
Now, I want to call them dynamically. See the example below
{%- set macro_names = ["cast_to_string", "convert_empty_string_to_null_value"] -%}
select
{% for macro_name in macro_names %}
-- this should dynamically be evaluated to `{{ cast_to_string(my_column) }}`
-- and `{{ convert_empty_string_to_null_value(my_column) }}`
{{ macro_name(my_column) }}
{% endfor %}
from my_model
However, this will throw an error saying that a string is not callable.
I also tried using {% raw %} {{ {% endraw %} to escape brackets, but that didn’t work either.
So, my question is, if there is a way to dynamically call macros in jinja/dbt?
I think it should work if you remove the quotes :
{%- set macro_names = [cast_to_string, convert_empty_string_to_null_value] -%}
So that jinja doesn't interpret it as string and you can use it as a Callable
I achieve it using this example :
{%- set macro_names = [print_lower, print_upper] -%}
{% for macro_name in macro_names %}
{{ macro_name("test") }}
{% endfor %}
and
{% macro print_lower(string) %}
{{ print(string|lower) }}
{% endmacro %}
{% macro print_upper(string) %}
{{ print(string|upper) }}
{% endmacro %}
I have a template folder containing a file.j2 , e.g
{% set summary %}
{% if summary %}
{{ summary }}
% endif %}
{% endset %}
I would like to use this summary variable in my yaml file but I can't seem to be able to find the information on how to reference the j2 file in the yaml file
Can I do this?
template: file.j2
summary: '{{ summary }}'
Any suggestions are greatly appreciated!
I am configuring a Jinja template in Cisco DNAC Template editor to provision new switches. The problem I am having is getting Jinja to split the string variable within the Cisco Template tool. I tried using this split command.
{% set list1 = variable1.split(';') %}
This works fine if I hard code in the {{ HOSTNAME }} variable, for example using ABC-DEF-111-AS-10-11-12-13
{# {% set hname = '{{ HOSTNAME }}' %} #}
{% set hname = 'ABC-DEF-111-AS-10-11-12-13' %}
Device name is {{ hname }}
{% set list1 = hname.split('-') %}
{% for list in list1 %}
<p>{{ list }}</p>
{% endfor %}
The campus is {{ list1[0] }}
The building is {{ list1[1] }}
Room number is {{ list1[2] }}
Switch type is {{ list1[3] }}
IP address is {{ list1[4] }}.{{ list1[5] }}.{{ list1[6] }}.{{ list1[7] }}
However, when I use the {{ HOSTNAME }} variable to input the hostname, the split command will not split the hostname, instead it passes the hostname through in its entirity within {{ list1[0] }}. This happens even if I use the variable directly within the split command, for example.
{% set list1 = '{{ HOSTNAME }}'.split('-') %}
I have also tried splitting the resultant {{ list1[0] }} but it too just passes the hostname on through in its entirety.
I am not sure if this is a problem with the version of Jinja used in the Template Editor because I get a systax error when ever I tried using this split command:
{% set item1, item2 = variable1.split(';') %}
Is there away to get {{ HOSTNAME }} split? What am I missing?
The solution is that I should change the variable into a statement like this:
{% set list1 = **HOSTNAME**.split('-') %}
I want to check if a specific version of a program is already installed.
Therefore, I got a state file:
{% set rvs = ['1113','1278'] %}
{% for rv in rvs %}
{% if ('r{{ rv }}' not in grains.get('cat12', [])) %}
... install it ...
{% else %}
... do nothing ...
{% endif %}
{% endfor %}
In my grains I have:
cat12:
- r1113
I would expect that '1278' is installed and list item '1113' triggers nothing, but even that is installed again...
There's no such syntax as using {{ and }} inside {% and %}. What's inside {% and %} is already Jinja. Just concatenate the string literal and the string variable with the ~ operator.
{% if 'r' ~ rv not in grains.get('cat12', []) %}
Or you can use the format filter:
{% if 'r%s'|format(rv) not in grains.get('cat12', []) %}
I have been trying to create a site with Github and I'm new to the whole thing. I have been struggling with a piece of code that has been giving me some headache:
{% for item in site.static_files %}
{% if item.path contains '/archive' %}
{% if item.path contains 'index.html' == false %}
{% assign split_path = item.path | split: '/' %}
<p>{{item.path}}</p>
{% assign filename = split_path.last %}
<p>{{ filename }}</p>
{% endif %}
{% endif %}
{% endfor %}
This generates the following error:
Error:
Liquid Warning: Liquid Syntax Error (line 5): Expected end_of_string but found comparison in "item.path contains 'index.html' == false" in archive/index.html
Can anyone help?
Replace:
if item.path contains 'index.html' == false
With:
unless item.path contains 'index.html'
Liquid's getting confused.
