Elasticsearch template not creating new index in elasticsearch 1.7

I have created a index template and inserted it in my local elasticsearch store. Using the following command:

curl -XPUT localhost:9200/_template/media_template -d '
{
    "template" : "media_*",
    "mappings" : {
        "properties": {
           "media-type": {
                "type": "string"
            }
        }
    }
}

I have installed Elasticsearch-head and can go into the Info>Templates and see that my template was indeed created. I am under the assumption that once I have a template then I can insert into any index with a name that fits within the regex of media_* even if that index does not yet exist. I want to be able to auto create indexes using the index template.

When I attempt to insert a record into an index that is not yet created, but is a valid regex of media_*, I get an error. Below is the insert statement that I call and after that is the error.

$ curl -XPOST 'http://localhost:9200/media_2016_03_25/1' -d '
{
 	"media-type" : "audio"
}
'

Error: 

{
  "error": "MapperParsingException[mapping [properties]]; nested: MapperParsingException[Root type mapping not empty after parsing! Remaining fields:   [media-type : {type=string}]]; ",
  "status": 400
}

What am I doing wrong? Am I misunderstanding index templates? Should they be able to auto create the index if it does not exist and is compliant with the template specification?

I am running elasticsearch 1.7

you need to specify which type you are applying your mapping to and what's the type of your document when you are creating it.

Try this : 

curl -XPUT localhost:9200/_template/media_template -d '
{
    "template" : "media_*",
    "mappings" : {
        "my-document-type" : {
            "properties": {
               "media-type": {
                    "type": "string"
                }
            }
        }
    }
}

Then this to create your document :

$ curl -XPOST 'http://localhost:9200/media_2016_03_25/my-document-type/1' -d '
{
    "media-type" : "audio"
}
'
