python - Django 搜索表单返回整个模型

Question

我正在尝试使用 Django 为基于类的 View 创建一个简单的搜索表单。一切似乎都有效，除了搜索结果返回整个模型，所以显然搜索/过滤器不起作用。在阅读了这里的一堆教程和问题后，我无法弄清楚为什么。

models.py:

class surveys(models.Model):
    FAN = models.SlugField(max_length=100, blank=True, null=True)
    Location = models.CharField(max_length=200, blank=True, null=True)

    def __str__(self):
        return self.FAN

    def get_absolute_url(self):
        return reverse('survey-detail', args=[str(self.FAN)])

views.py:

class Search(generic.ListView):
    template_name = 'datalibrary/search.html'
    model = surveys

    def get_queryset(self):
        try:
            name = self.kwargs['name']
        except:
            name = ''
        if (name != ''):
            object_list = self.model.objects.filter(FAN__icontains == name)
        else:
            object_list = ''
        return object_list

class SearchResults(generic.ListView):
    template_name = 'datalibrary/search_results.html'
    model = surveys

search.html:

{% extends "base_generic.html" %}

{% block content %}
    <form method="get" action="/results/" class="navbar-form pull-right">
        <input type="text" id="searchBox" class="input-medium search-query" name="search" placeholder="Search">
        <input type="submit" class="btn" value="Search" >
    </form>
{% endblock %}

search_results.html:

{% extends "base_generic.html" %}

{% block content %} 
    {{ object_list }}
{% endblock %}

urls.py:

urlpatterns +=[
    path('search/', views.Search.as_view(), name='search'),
    path('results/', views.SearchResults.as_view(), name='search-results'),
]

知道为什么 object_list 返回模型中的所有值，而不是根据输入进行过滤，即使没有输入也是如此？

你有name = self.kwargs['name']，它没有得到任何'name'，对于搜索来说，更好的方法是将输入的名称作为查询并显示结果。

class Search(generic.ListView):
    template_name = 'datalibrary/search.html'
    context_object_name = 'all_search_results'

    def get_queryset(self):
        result = super(Search, self).get_queryset()
        query = self.request.GET.get('search') #your input name is 'search'

        if query:
           object_list = surveys.objects.filter(FAN__icontains=query) #or FAN__contains
           result = object_list
        else:
           result = None    # When no result found

        return result

在 HTML 中，

{% extends "base_generic.html" %}

 {% block content %}
  <form method="get" action="/results/" class="navbar-form pull-right">
     <input type="text" id="searchBox" class="input-medium search-query" name="search" placeholder="Search">
     <input type="submit" class="btn" value="Search" >
  </form>



  {% for result in all_search_results %}
       {{result.add_according_to_the_model}}
  {% empty %}
        <p> No Results <p>
  {% endfor %}

   {% endblock %}

您可以在同一页面中显示搜索结果。但是，如果您需要，那么您可以使用不同的 html。
