Django Search functionality: form returns None-CodePudding

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>

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)

CodePudding user response：

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)
```

CodePudding user response：

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)
