how to implement search that can access complete database in Django

Question

My views.py

class SearchView(TemplateView):
    template_name = 'search.html'

    def get(self, request, *args, **kwargs):
        q = request.GET.get('q', '')
        self.results = Item.objects.filter(title__icontains=q)
        return super().get(request, *args, **kwargs)

    def get_context_data(self, **kwargs):
        return super().get_context_data(results=self.results, **kwargs)

My urls.py

url(r'^search/$', SearchView.as_view(), name='search')

My search.html

{% extends 'base.html' %} {% load static %} {% block content %}

<body>
    <h1>Search Result</h1>
    <ul>
        {% for item in q %}
        <li>
            {{ q.title }}, {{ q.price }}
        </li>
        {% endfor %}
    </ul>

</body>
{% endblock%}}

My nav.html

<form method="GET" action="{% url 'core:search' %}">

This is the code that i used but due to some missing or error in this above code i can't get any data if i make any search in my website, Can some one please tell me what is the mistake i have done. Thank you.

My Models.py

class Item(models.Model):
    title = models.CharField(max_length=50)
    category = models.ForeignKey(Category, on_delete=models.CASCADE)
    model_no = models.CharField(max_length=100)

I think you should use {{ item.title }}, {{ item.price }} in the template instead of {{ q.title }}, {{ q.price }} — Siva Sankar

My Models.py code class Item(models.Model): title = models.CharField(max_length=50) category = models.ForeignKey(Category, on_delete=models.CASCADE) model_no = models.CharField(max_length=100) — I.SRI RAM

why are you using products in this line: {% for item in products %}, where is it coming from? — Siva Sankar

try this:

    def get_context_data(self, *, object_list=None, **kwargs):
        context = super().get_context_data(**kwargs)
        context['results'] = self.results
        return context

in html

{% extends 'base.html' %} 
{% load static %} 

{% block content %}

<body>
    <h1>Search Result</h1>
    <ul>
        {% for item in results %}
        <li>
            {{ item.title }}, {{ item.price }}
        </li>
        {% endfor %}
    </ul>

</body>
{% endblock%}}

should i change any thing in my urls.py or not.

OlegТ Over a year ago

write this: url('search/', SearchView.as_view(), name='search') You have to get your "q" in get() function from somewhere, so that the url must be something like 'search/?q=abc'.

I tried to execute the changed code but it is showing error at context in views.py
