How should I POST and serialize and array of arrays with DRF? - django

Question

I'm having an issue POST-ing a JSON object that contains and array of arrays and deserializing it using Django Rest Framework.
The idea here is that there can be a dynamic number of players (players: 2) and a list of lists/array of arrays of weapons that the players have (player_weapons [[], []]).
//javascript on client
var post_data = {
players: 2,
player_weapons: [
["sword", "shield"],
["mace", "slingshot"],
]};
var results = jQuery.post( url, post_data );
#serializers.py
class GameSerializer(serializers.Serializer):
players = serializers.IntegerField(min_value=1)
player_weapons = serializers.ListField(
child=serializers.ListField(
child=serializers.CharField(min_length=1, allow_blank=True),
min_length=0,
required=False),
min_length=0,
required=False
)
The request.POST I get is:
<QueryDict: {'runs': ['1000'], 'additional_players': ['2'],
'player_weapons': ['sword,shield', 'mace,slingshot']}>
What's really weird is that when I do request.POST['player_weapons'] I get:
mace,slingshot
whereas I'm expecting/hoping to get:
[['sword', 'shield'], ['mace', 'slingshot']]
Any help on how I should be structuring the POST and handling it in DRF would be awesome.

Thanks to RishiG for the help here.
Problem was that I wasn't specifying the contentType in the request. I slightly modified it to use jQuery's ajax request:
var posting = jQuery.ajax({
url: url,
type: "POST",
data: JSON.stringify(post_data),
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function(){
}
});
