我有一个模板:

    ...
    <form action="/reportform/" method="post">
    <p><label>Aircraft system:</label>
    <br>{{ Querry.system }}
    ...

它看起来像这样

如何为此框设置尺寸选项？例如,10.

class Report(models.Model):
    precursor = models.ManyToManyField(Precursor)

class ReportAdmin(admin.ModelAdmin):
    def formfield_for_manytomany(self, db_field, request, **kwargs):
        ops_area = Report.objects.get(id=???????).ops_area
        print id
        print ops_area
        if db_field.name == "r_precursor":
            kwargs["queryset"] = Precursor.objects.filter(ops_area=ops_area)
            print kwargs
        return super(ReportAdmin, self).formfield_for_manytomany(db_field, request, **kwargs)

如何给出def formfield_for_manytomany可编辑对象的id？

我有一个模型、视图和模板：

模型

class Peoples(models.Model):
    l_name = models.CharField(max_length=50)
    f_name = models.CharField(max_length=50)
    m_name = models.CharField(max_length=50)
    tab_number = models.CharField(max_length=5)
    birthday = models.DateField(null=True, blank=True)
    post = models.CharField(max_length=250, blank=True)
    workplace = models.ForeignKey(Workplace, null=True, blank=True)
    skill = models.CharField(max_length=20, blank=True)
    dopuska = models.TextField(blank=True)
    srok_dopuskov = models.DateField(null=True, blank=True)
    photo = models.ImageField(upload_to='img',blank=True)
    class Meta:
        ordering = ('l_name',)
    def __unicode__(self):
        return self.l_name
    def age(self):
        import datetime
        return int((datetime.datetime.now() - self.birthday).days / 365.25  )
    age = property(age)

看法

def view_persone(request, tab_number):
    return direct_to_template(request, 'person.html', {
       'persone': Peoples.objects.filter(tab_number=tab_number),
    })

模板

{% for …

我有两节课:

class People
    name = CharField()

class Equipment
    name = Charfield()
    responsible = ForeignKey(People)

并查看:

def persone_detail(request, tab_number):
    return direct_to_template(request, 'person.html', {
       'persone': Peoples.objects.filter(tab_number=tab_number)

我怎样才能显示模板的名称从设备？

我有一个变量:

x = 4

我有一个清单:

list = [{'name': u'A', 'value': '1'}, {'name': u'B', 'value': '4'}, {'name': u'C', 'value': '2'}]

如何排除/删除列表中value = x的元素？

是否可以使用机器人更改不和谐服务器所有者的昵称？

更新。我有电子服务器。我想给我的机器人更改我昵称的权利。我可以这样做吗？
