Django – User Search

I’m trying to filter ListView based on post method from search bar in my basetemplate. So making it works like:

 Insert name --> SearchBar-->GET Method-->SearchView class(in views.py)--> render html with usernames.

I have done this, but it wont work. Could you please tell me what I’m doing wrong?

views.py in my user app

class SearchView(ListView):
    model = User
    template_name = 'blog/list_of_users.html'
    context_object_name = 'all_search_results'

    def get_queryset(self):
       result = super(SearchView, self).get_queryset()
       query = self.request.GET.get('search')
       if query:
          postresult = User.objects.filter(username__contains=query)
          result = postresult
       else:
           result = None
       return result

urls.py in my blog app

path('users_search/?search=<str:username>', user_view.SearchView.as_view(), name='user_search'),

search form in html

  <form class="example" method="GET">
                <input type="search" placeholder="ユーザー検索..." name="user_name">
                  <button type="submit">
                    検索
                  </button>

rendered html with user names

{% for result in all_search_results %}
   {{ result.username }}
{% empty %}
   add something to show no results
{% endfor %}

Answer

override get_context_data method

def get_context_data(self, **kwargs):
    context = super().get_context_data(**kwargs)
    user_name = self.request.GET.get('user_name', '')
    context['all_search_results'] = User.objects.filter(username__icontains=user_name )
    return context

In your template

<form class="example" method="GET">
    <input type="text" placeholder="ユーザー検索..." name="user_name">
    <button type="submit">
        検索
     </button>
</form>

{% for result in all_search_results %}
   {{ result.username }}
{% empty %}
   add something to show no results
{% endfor %}

Update:

in template, <input ........... name="search">

in views, user_name = self.request.GET.get('search', '')
