get results from one view to another view in django

Question

I have two views. 1 gets results from search, 2 shows results in html file. I know I can combine 2 views to 1, after getting results and showing it. I need to separate two function because after getting results from 1, I can show it, using it with pagination and using it with next/back function I try to use request.session to get data from view 1 to view 2 but It fails View 1

def list_contract_test(request):
context = {}
if request.method == 'GET':
    query1= request.GET.get('search1')
    query2= request.GET.get('search2')
    submitbutton= request.GET.get('submit')
    if query1 is not None:
        lookups_contract= Q(contract__icontains=query1)
        lookups_name = (Q(name__icontains=query2.upper())|Q(name__icontains=query2.lower()))
        contract_posts= Contracts.objects.filter(lookups_contract,lookups_name).distinct()
        context['contract_posts'] = contract_posts
        request.session['contract_posts'] = contract_posts
        return render(request, "customer2.html", context)
    else:
        contract_posts= Contracts.objects.all()
        context['contract_posts'] = contract_posts
        return render(request, 'customer2.html', context)
else:
    return render(request, 'customer2.html')

View 2

def get_data(request):
    contract_posts_test = request.session['results']
    context['contract_posts_test'] = contract_posts_test
    return render(request, 'customer2.html', context)

In my template customer2.html

 {% for contract in contract_posts_test %}
                    <tr>
                      <td><a href="{% url 'contract_detail' contract_id=contract.contract %}">{{contract.contract}}</a></td>
                      <td>{{ contract.name }}</td>
                      <td>{{ contract.debt }}</td>
                      <td>{{ contract.created_at}}
                    </tr>
                  {% endfor %}

In my url

path("customer2/",get_data,name="get_data"),

The error shows:

...views.py, line 196, in get_data
            return render(request, 'customer2.html',results)
    else:
        return render(request, 'customer2.html')
#request.session['list'] = list_to_process
#list_to_process = request.session['list']
def get_data(request):
    contract_posts_test = request.session['results'] … #error this line
    #contract_posts_test = val1()
    context['contract_posts_test'] = contract_posts_test
    return render(request, 'customer2.html', context)
