fix list field accept dict parameter bug

[Friday21]

when I use List field with nested object field, I find out when the client pass the object filed(not as list), the parameter check didn't throw parameter error(400), so I got a json object in my view layer, that is not what I expected, thus trigger a bug。

Thanks for contributing! Could you please provide some example code to reproduce the issue in the same way you encountered it?

I think the test case I add in test_format_error has already include one example

I see the test case (thank you for that), however it's not a full example of the use case that you described. Calling the format method on a field directly is very different to how it is used when receiving a POST payload

OK, so here is my example in real project(change some name to hide work info):

first, the input model definition:

time_fields = api.model('TimeInput', {
    'id': fields.Integer(required=True, description='ID'),
    'time_area_list': fields.List(fields.List(fields.Integer), required=True,
                                  description='time area, ex： [[t1, t2], [t3, t4], [t5], [t6, t7]...]')
})

test_list_fields = api.model('TimelistInput', {
    'list_time': fields.List(fields.Nested(time_fields), required=True),
})

and, here is the code in the rest api code:

@time_api.route('/beat', methods=['POST', 'PUT'])
class TimeResource(Resource):
    @time_api.expect(input.test_list_fields)
    def post(self):
        """"""
        payload = self.api.payload
        time_list = payload.get('list_time')
        print(time_list)
        return response(ResponseCode.SUCCESS, msg='success')

and then, I send request through postman with list_time field as list of object

this works as expected. then I send list_time field as object:

it should have return parameter error, but it didn't, it just pass on. the print info is below:
