在HTML中用Django框架查询MYSQL

Question

我正在用Django框架和googleapi+MYSql构建一个站点。目前，我把数据库中所有数据项的纬度和经度显示在热图图层上

我需要能够过滤我的数据，以完善我的显示。e、 g-我想按“Slip”和“trip”等类型过滤HazardInside.title

这个过滤器将需要能够同时过滤许多其他要求，如日期和天气条件。e、 g title=“Slip”+weather=“Wet”+日期之间（dd/mm/yy-dd/mm/yy）

我当前的问题是成功地创建一个视图，该视图从我的dB请求新数据并将其解析到我的HTML页面

型号.py

class HazardInside(models.Model):

    title = models.CharField(max_length=50)
    description = models.CharField(max_length=250)
    incident_date = models.DateField(auto_now=False)
    lat = models.FloatField(max_length=25, default=0.00000)
    lng = models.FloatField(max_length=25, default=0.00000)
    room_number = models.CharField(max_length=25)
    floor = models.CharField(max_length=10)

    def __unicode__(self):
        return self.title


class InjuryInside(models.Model):

    title = models.CharField(max_length=50)
    description = models.CharField(max_length=250)
    incident_date = models.DateField(auto_now=False)
    lat = models.FloatField(max_length=25, default=0.00000)
    lng = models.FloatField(max_length=25, default=0.00000)
    room_number = models.CharField(max_length=25)
    floor = models.CharField(max_length=10)

    def __unicode__(self):
        return self.title

视图.py

from django.shortcuts import render, HttpResponse
from qutheatmap.models import Markers, HazardInside, InjuryInside
from django.template import RequestContext
from django.shortcuts import render_to_response

def home(request):
    marker = Markers.objects.all()
    hazardinsides = HazardInside.objects.all()
    injuryinsides = InjuryInside.objects.all()

    mapdata = {
        'markers': marker,
        'hazardinsides': hazardinsides,
        'injuryinsides': injuryinsides
    }

    return render(request, 'heatmap/map.html', mapdata)

def search(request):
    query = request.GET.get('type')
    try:
        query = char(query)
    except ValueError:
        query = None
        hazardinsides = None
    if query:
        hazardinsides = HazardInside.objects.get(title=query)
    context = RequestContext(request)

    mapdata = {
        'markers': marker,
        'hazardinsides': hazardinsides,
        'injuryinsides': injuryinsides
    }

    return render_to_response('heatmap/map.html', {"hazardinsides": hazardinsides,}, context_instance=context)

在我的html中

<form method="get" action="http://localhost:8000/qutheatmap/">
  Search:<input type="text" name="type" id="id_q" value="{{ query }}"/>
  <input type="submit" value="Search" />
</form>

我用我有限的Django知识尝试了几种不同的方法，但没有效果，例如：

1. Django form to query database (models)
2. Querying a django DB with model forms

编辑：

网址

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^$', views.home),
    url(r'^$', views.search),
]

URL配置

from django.contrib import admin
from django.conf.urls import url, include
from qutheatmap import views

urlpatterns = [
    url(r'qutheatmap/', include('qutheatmap.urls')),
]
