Hello,

I am struggling with this kind of structure :

{  
“out.results”: [  
{  
“\_ansible\_item\_result”: true,  
“\_ansible\_no\_log”: false,  
“\_ansible\_parsed”: true,  
“changed”: false,  
“exitcode”: “NoChangeNeeded”,  
“feature\_result”: ,  
“item”: “A”,  
“restart\_needed”: false,  
“success”: true  
},  
{  
“\_ansible\_item\_result”: true,  
“\_ansible\_no\_log”: false,  
“\_ansible\_parsed”: true,  
“changed”: false,  
“exitcode”: “NoChangeNeeded”,  
“feature\_result”: ,  
“item”: “B”,  
“restart\_needed”: false,  
“success”: true  
},  
{  
“\_ansible\_item\_result”: true,  
“\_ansible\_no\_log”: false,  
“\_ansible\_parsed”: true,  
“changed”: false,  
“exitcode”: “NoChangeNeeded”,  
“feature\_result”: ,  
“item”: “C”,  
“restart\_needed”: false,  
“success”: true  
},  
{  
“\_ansible\_item\_result”: true,  
“\_ansible\_no\_log”: false,  
“\_ansible\_parsed”: true,  
“changed”: false,  
“exitcode”: “NoChangeNeeded”,  
“feature\_result”: ,  
“item”: “D”,  
“restart\_needed”: true,  
“success”: true  
}  
]  
}

And I want to catch if restart\_needed is true … any help is welcome.

Regards

What you need to use here is selectattr and equalto from jinja2:

results\>selectattr(‘restart\_needed’, ‘equalto’, true)|list|length

If my memory is correct, `equalto` was not added until jinja2 v2.8

Actually that can be simplified, I completely forgot that the default for selectattr is to check if the value is true.

So:

results\>selectattr(‘restart\_needed’)|list|length

That doesn’t even require the `equalto` test.

thanks it works fine !!

PS : Do you know how to put jinja code in task/role/play ? or do you have to put it in default.yml files ?
