  1. PODjango pagination error
    text
    copied!<p>I have created a Django application. There is a filtering functionality in my application. The filtered data is shown in a separate page.</p> <p>Now I want to give Django Pagination to the filtered list page. While doing it, I came into this error. The pagination is shown at the bottom of the page with showing the correct number of pages NEXT.</p> <p>But while clicking on the 'Next Page' in paginator it redirects me to my home page (/employeeList).</p> <p>I suppose it is because of an <code>HttpResponseRedirect (return HttpResponseRedirect('/employeeList'))</code> I give inside the <code>filter()</code> which is used in some cases. I will paste my filter() and the HTML for pagination.</p> <pre><code>def filter(request): val2='' val3='' newData='' if request.GET.has_key('choices'): val2=request.GET.get('choices') if request.GET.has_key('textField'): val3=request.GET.get('textField') if request.POST: val2=request.POST.get('choices') val3=request.POST.get('textField') if val2=='Designation': newData = EmployeeDetails.objects.filter(designation=val3) flag=True elif val2=='Name': newData = EmployeeDetails.objects.filter(userName__icontains=val3) flag=True elif val2=='EmployeeID': newData = EmployeeDetails.objects.filter(employeeID=val3) flag=True elif val2=='Project': newData = EmployeeDetails.objects.filter(project=val3) flag=True elif val2=='DateOfJoin': newData = EmployeeDetails.objects.filter(dateOfJoin=val3) flag=True else: return HttpResponseRedirect('/employeeList') if request.POST.get('sortAscendValue'): newData = newData.order_by('userName') elif request.POST.get('sortDescendValue'): newData = newData.order_by('-userName') paginator = Paginator(newData, 10) try: page = int(request.GET.get('page', '1')) except ValueError: page = 1 try: contacts = paginator.page(page) except (EmptyPage, InvalidPage): contacts = paginator.page(0) return render_to_response('filter.html',{'newData':newData,'emp_list': contacts,'val2':val2,'val3':val3,'flag':flag,'emp_list': contacts}) </code></pre> <p><strong>filter.html</strong></p> <pre><code>&lt;div class="pagination" &gt; &lt;span class="step-links"&gt; {% if emp_list.has_previous %} &lt;a href="?page={{ empl_list.previous_page_numbe }}"&gt;Previous&lt;/a&gt; {% endif %} &lt;span class="current"&gt; Page {{ emp_list.number }} of {{ emp_list.paginator.num_pages }}. &lt;/span&gt; {% if emp_list.has_next %} &lt;a href="?page={{ emp_list.next_page_number }}"&gt;Next&lt;/a&gt; {% endif %} &lt;/span&gt; &lt;/div&gt; </code></pre>
