从django模型创建javascript对象（类） [英] Create javascript object (class) from django model

问题描述

我正在开发一个单页应用程序，将从大约十几个不同的django模型加载数据，允许用户操作数据，然后将所有更改保存回数据库。

我可以通过序列化查询集的结果来将django模型传递到模板。例如，我有一个模型Person：

  class Person（models.Model）：
 id = models.AutoField （primary_key = True）
 age = models.IntegerField（）
 name = models.CharField（max_length = 250）
  

现在，在我看来，我可以通过序列化将一个person对象传递给json格式的模板

  person_object = serializers.serialize（json，Person.objects.filter（id = 1））
  

b $ b

然后，在我的javascript：

  var someperson = {{data | safe}}; 
  

但是，我想在客户端创建一个如果Person是javascript类，而不是简单的json对象：

  var person2 = new Person（id = 5，age = 33m ，name =john）; 
  

我的javascript类是否有继承Django数据模型的方法？或者我需要在django和javascript之间手动重新创建我的数据模型？

解决方案

整个

  person ='new Person（id =％（id）s，age =％ ，name =％（name）s）'％
 {'id'：person_instance.id，....} 
   
 
然后将其作为上下文变量发送到模板，所以它看起来像这样
  var person2 = {{person}}; 
  
 
I am working on an single-page application that will load up data from about a dozen different django models, allow the user to manipulate the data, and then save all changes back to the database.

I can sort of 'pass' the django model to template by serializing a result from a queryset. For example, I have a model Person:
class Person(models.Model):
    id = models.AutoField(primary_key=True)
    age = models.IntegerField()
    name = models.CharField(max_length=250)
Now, in my view, I can pass a "person" object to the template in json format by serializing it
person_object = serializers.serialize("json", Person.objects.filter(id=1))
Then, in my javascript:
var someperson = {{ data|safe }};
However, I would like to be able to create a "new" person on the client side, as if the Person were a javascript class not simply a json object:
var person2 = new Person(id=5,age=33m,name="john");
Is there a way for my javascript "class" to inherit the Django data model? Or do I need to manually re-create my data models between django and javascript?
解决方案
You can put the in a string as a whole
person = 'new Person(id="%(id)s",age="%(age)s",name="%(name)s")' %
 {'id':person_instance.id , ....}
then send it to the template as a context variable , so it look like this
var person2 = {{ person }} ;
