这是django rest_framework API我为restourant创建了这个api.这是menu api .我想把menu.json的数据保存到我的数据库，但是我不能.你能给予我一些建议把json数据保存到我的模型吗？

File "C:\Users\OSMAN MERT\Desktop\menu\menu_core\api\models.py", line 36, in store_json_data
        meal, created = Meal.objects.get_or_create(name=meal_data.get('name', ''))
    AttributeError: 'str' object has no attribute 'get'

我该怎么解决？我需要你的帮助？
models.py

from django.db import models
    import json
    # Create your models here.
    
    class Meal(models.Model):
        id = models.AutoField(primary_key=True)
        name = models.CharField(max_length=100)
        is_vegetarian = models.BooleanField(default=False)
        is_vegan = models.BooleanField(default=False)
    
    class Ingredient(models.Model):
        id = models.AutoField(primary_key=True)
        name = models.CharField(max_length=100)
        groups = models.CharField(max_length=100)
    
    class Option(models.Model):
        id = models.AutoField(primary_key=True)
        ingredient = models.ForeignKey(Ingredient, on_delete=models.CASCADE)
        name = models.CharField(max_length=100)
        quality = models.CharField(max_length=100)
        price = models.FloatField()
        per_amount = models.CharField(max_length=100)
    
    class MealIngredient(models.Model):
        id = models.AutoField(primary_key=True)
        meal = models.ForeignKey(Meal, on_delete=models.CASCADE)
        ingredient = models.ForeignKey(Ingredient, on_delete=models.CASCADE)
    
    
    
    
    path = r"C:\Users\OSMAN MERT\Desktop\menu\menu_core\menu.json"
    
    def store_json_data(json_data):
        for meal_data in json_data:
            meal, created = Meal.objects.get_or_create(name=meal_data.get('name', ''))
            if not created:
                meal.is_vegetarian = meal_data.get('is_vegetarian', False)
                meal.is_vegan = meal_data.get('is_vegan', False)
                meal.save()
            for ingredient_data in meal_data.get('ingredients', []):
                ingredient, _ = Ingredient.objects.get_or_create(name=ingredient_data.get('name', ''), meal=meal)
                for option_data in ingredient_data.get('options', []):
                    option, _ = Option.objects.get_or_create(quality=option_data.get('quality', ''), ingredient=ingredient)
                    option.price = option_data.get('price', 0)
                    option.save()
    
    def load_json_file(path):
        with open(path) as json_file:
            json_data = json.load(json_file)
            store_json_data(json_data)
    
    load_json_file(path)

这是来自menu.json的一些数据，并非所有代码都包含在其中。menu.json
