小编Pra*_*edi的帖子

我有以下型号:

class Stop(models.Model):
    name = models.CharField(max_length=50)
    point = models.PointField()
    objects = models.GeoManager()

我想从北到南排序.我该怎么做呢？ Stop.objects.order_by('point')他们从西向东排序.

谢谢.

这是我的完整模型:

from django.contrib.gis.db import models
from django.core.urlresolvers import reverse

class Stop(models.Model):
    gtfs_stop_id = models.IntegerField(db_index=True, unique=True)
    name = models.CharField(max_length=50)
    point = models.PointField()
    parkings = models.GeometryCollectionField(null=True, blank=True)
    objects = models.GeoManager()

    def get_absolute_url(self):
        return reverse('core:stop', args=(self.id,))

    def __str__(self):
        return self.name

我想在同一行上显示两个表单字段，而不是一个接一个。

目前，我得到：

Choice a theme :
   . Datasystems
   . Cameroun

但我想显示这个表格，如：

Choice a theme:
       . Datasystems                    . Cameroun

我的.html 文件看起来像：

{% extends 'Base_Configurations.html' %} 
{% load staticfiles %} 
{% load static %} 
{% block title %}
    <h3> <span class="glyphicon glyphicon-file"></span> Choix du thème DatasystemsEC </align> </h3>
{% endblock %}

{% block content %}

    <form class="form" method='POST' action=''> {% csrf_token %}
        <br></br>
        {{ form }}
        <br></br>
        <input class="button" type="submit" value="Valider le thème" />
    </form>

{% endblock %}

我还有一个.css …

我正在尝试在Django中安装django-oauth2-provider.在安装和配置settings.py之后,在迁移期间,我收到的错误如下:

Django 新手，感觉我快要弄清楚我哪里出错了。我一直试图将上下文传递给我的模板，但无济于事。在模型中，我有：

class Rate(models.Model):
    name = models.CharField(max_length = 140)
    ratings =  GenericRelation(Rating, related_query_name= 'object_list')

    def __str__(self):
        return self.id

在视图中，

def RateList(request):
    queryset = Rate.objects.filter(ratings__isnull=False).order_by('ratings__average')
    context= {
        "object_list": queryset,
        "title": "List"
    }
    return render(request, 'UploadApp/upload.html', context)

最后，在我的模板中，我{% ratings object_list %}按照文档将 HTML 放入了 HTML 中。不确定我是否只是忽略了一些小细节，但是'str' object has no attribute 'meta'当我尝试加载页面时出现错误。任何帮助表示赞赏，我在拉头发阶段
