在 django 中实现搜索

Question

我有这个 html 搜索表单，我想将它链接到我的搜索视图以使其工作。

<form class="navbar-form navbar-left" role="search" >
    <div class="form-group">
        <input type="text" class="form-control" placeholder="Search" action = "/search/">
    </div>
    <button type="submit" class="btn btn-default">Submit</button>
</form>

这里是视图。

def searchResults(request, drname):
    # drname = request.GET.get('drname')
    doctors = Doctor.objects.filter(name__contains=drname)
    clinic = Doctor.objects.filter(clinic__name__contains=drname)
    d = getVariables(request)
    d['doctors'] = doctors
    d['doctors_by_clinic'] = doctors
    return render_to_response('meddy1/doclistings.html',d)

urls.py

url(r'^search/(?P<drname>\w+)/$', views.searchResults, name='searchResults'),  

Answer 1

1. HTML。 <form> 必须有 action 属性，而不是 <input>。另外，将搜索字符串作为 get 参数发送，不要将其包含在 url 中（将 name 属性添加到 <input>）：

   <form class="navbar-form navbar-left" role="search" action="/search/">
       <div class="form-group">
           <input type="text" class="form-control" placeholder="Search" name="drname">
       </div>
       <button type="submit" class="btn btn-default">Submit</button>
   </form>
   

2. urls.py。删除这部分(?P<drname>\w+)/:

   url(r'^search/$', views.searchResults, name='searchResults'),
   

3. views.py。从GET参数获取搜索字符串：

   def searchResults(request):
       drname = request.GET.get('drname')
       doctors = Doctor.objects.filter(name__contains=drname)
       clinic = Doctor.objects.filter(clinic__name__contains=drname)
       d = getVariables(request)
       d['doctors'] = doctors
       d['doctors_by_clinic'] = doctors
       return render_to_response('meddy1/doclistings.html',d)
   

Answer 2

action 进入 form 元素，而不是输入。
