Question

下面是简单的数据库模式,即:

class Notes(db.Model):
  text = db.StringProperty(multiline=True)
  date = db.DateTimeProperty(auto_now_add=True)

现在,在导游手里,我向模板发送所有说明如下:

class MainPage(webapp2.RequestHandler):
  def get(self):
    notes = Notes.all()
    self.render_template("index.html", { notes :notes})

{% for note in notes %}
<p>  
 {{ note.text }} <br>
 {{ note.date }} <br>
 (<a href ="edit/{{note.key.id}}">edit </a>)
{% endfor %}

But the trouble is, i dont see anything printed, in place of note.key.id As per the docs over here key class represents a unique key for a database entity and this has a method id, its a numeric value. for a single note from the collection of notes i want the id of the note.

如果一使用django轮机,一则有以下数值:{附注.key.id <>code>印刷,但附有jinja2。 i 随行。



如何做到这一点?

Answer 1

取代<代码>href 符合以下规定:

(<a href ="edit/{{note.key().id()}}">edit </a>)

这足够了。
