Pagination In Django - The Original Query String Gets Lost

I use the code from the documentation to paginate the data: try: data = paginator.page(request.GET.get('page')) except PageNotAnInteger: page = 1 data = paginator.page(

Solution 1:

You can access parameters from your request directly in your template if you activate django.core.context_processors.request in your settings. See https://docs.djangoproject.com/en/1.7/ref/templates/api/#django-core-context-processors-request

Then you can access parameters in your template directly. In your case you'll need to filter page parameter. You could do something like this:

href="?page={{ data.next_page_number }}{% for key, value in request.GET.items %}{% if key != 'page' %}&{{ key }}={{ value }}{% endif %}{% endfor %}"

Solution 2:

Another possible solution can be to construct parameters list in your view. Pros: you can use clean and expressive methods on QueryDict.

It will be look like this:

get_copy = request.GET.copy()
parameters = get_copy.pop('page', True) and get_copy.urlencode()
context['parameters'] = parameters

That's it! Now you can use your context variable in template:

href="?page={{ paginator.next_page_number }}&{{ parameters }}"

See, code looks clean and nicely.

note: assumes, that your context contained in context dict and your paginator in paginator variable

Solution 3:

The easy way would be to include those variables in your template:

<ahref="?var1={{var1}}&var2={{var2}}&page={{ data.next_page_number }}">next</a>

Just add var1 and var2 to your context.

That's if the query string variables are originated from your backend. If they're coming from the front-end/external, you could use something like How can I get query string values in JavaScript? in your template and either edit the template vars directly or pass the values to your backend.

Solution 4:

Similar to YPCrumble's answer, the following snippet works for me. But the template files could get pretty crowded when there are multiple parameters.

<ahref="?p={{ page }}{% if search %}&search={{ search }}{% endif %}">{{ page }}</a>

Note that you must know the parameter names when apply this solution, so it may not fully satisfy your need.
