Django Search functionality: form returns None - django

Question

i am trying to build a django search functionality for my app but the input form keeps returning a none
views.py
def search(request):
if request.method == 'POST':
query = request.POST.get('text')
houses = Product.objects.filter(name__contains='query')
context = {
'houses':houses,
}
return render (request, 'searchresult.html', context)
search.html
<form>
<input type='text' placeholder='search houses>
<button type='submit'>Search</button>
</form>

Answer 1

First off, your python indentation is invalid, and your HTML is also invalid on the input line. I will assume this is a typo in the question, but if not, you have issues there.
Your main problem is the filter for houses:
houses = Product.objects.filter(name__contains='query')
is looking for a name containing the string "query". You need the variable you've just defined.
houses = Product.objects.filter(name__contains=query)

Answer 2

You have an indentation issue in the code you have posted.
You need to add action and method in your Form.
<form action="/url_of_search/" method="post">
Missing quote in input line.
<input type='text' placeholder='search houses'>
You need to use query instead of 'query' in the filter.
Product.objects.filter(name__contains=query)

Answer 3

Things missing in html code:
form action attribute
form method attribute
input field name attribute
<!-- add form attributes method and action -->
<form method="POST" action="{% url '<url_name>' %}">
<!-- add input attribute name to identify the field and pass the value in request body -->
<input type='text' placeholder='search houses' name='search_text'>
<button type='submit'>Search</button>
</form>
update views for search
def search(request):
if request.method == 'POST':
# use input field name to get the search text
query = request.POST.get('search_text')
houses = Product.objects.filter(name__contains=query)
context = {
'houses':houses,
}
return render (request, 'searchresult.html', context)
