How do I convert an array to string using the jinja template engine?

Question

I have an array element called "tags" and would like to convert the array of tags to strings separated by a blank space. But how do you do that in Jinja?

I have tried:

{{ tags|join }} 

Answer 1

Actually you are almost there, for join with space, just put it like this:

{{ tags|join(' ') }} 

see the jinja docs for more details
