从模板传递对象以使用Django进行查看 [英] Passing objects from template to view using Django
问题描述
我试图找出以下应用程序的架构：
I am trying to figure out the architecture for the following app:
- 给用户一张桌子。
- 每个表单元格都有几个用户填写的字段。
- 有一个常规提交按钮：点击所有输入数据（连同一些计算
以下是以下问题：
-
我可以将数据结构组织为一组对象，方法是每个对象都对应一个表单元格，而主对象将最终传递给Django视图，将会是一组这些对象？
Can I organize the data structure as a set of objects in a way that each object will correspond to a table cell, whereas the Master object, that will eventually be passed to the Django view, will be a set of those objects?
如果是这样，如何从模板传递主对象以查看使用Django？
If so, how to pass the Master object from a template to view using Django?
谢谢。
推荐答案
<强> 1。可以在HTML / JS中创建一个对象，其成员将包含字段中的数据？
您不能在html / JS中创建对象，但是您可以构建代码以在Django中显示或请求数据。
You can't create an object in html/JS, but you can build your code up to display or request data from an object in Django.
举个例子，你有一个模型Foo
Say for example, you have a model Foo
class Foo(models.Model):
GENDER = (
('F', 'Female'),
('M', 'Male'),
)
name = models.CharField(max_length=150)
gender = models.CharField(max_length=1, choices=GENDER)
您的模板看起来像这样
<body>
<form action="?" method="post">
<table>
<tr>
<td>Name</td>
<td><input type="text" name="name" maxlength="150" /></td>
</tr>
<tr>
<td>Gender</td>
<td>
<select name="gender">
<option value="F">Female</option>
<option value="M">Male</option>
</select>
</td>
</tr>
</table>
<input type="submit">
</form>
</body>
如果您填写字段并单击提交，那么您可以处理视图中的数据。 / p>
If you fill in the fields and click submit, then you can handle the data in your view.
def add_foo(request):
if request.method == "POST": # Check if the form is submitted
foo = Foo() # instantiate a new object Foo, don't forget you need to import it first
foo.name = request.POST['name']
foo.gender = request.POST['gender']
foo.save() # You need to save the object, for it to be stored in the database
#Now you can redirect to another page
return HttpResponseRedirect('/success/')
else: #The form wasn't submitted, show the template above
return render(request, 'path/to/template.html')
最后一点也回答了问题2，我想。希望这有帮助。
That last bit also answered question 2, i think. Hope this helps.
