jlubcke / tri.query Goto Github PK

tri.query makes it easy to implement searching and filtering in your Django app.

Major features:

• Generate simple filtering GUIs easily while at the same time:
• Supply your views with advanced query languages
• Query language can be used stand alone without the GUI parts
• Highly customizable GUI based on tri.form

Simple view that allows the user to search for a car by choosing the make from a drop down, and search for specific model in the advanced mode:

class CarQuery(Query):
    make = Variable.choice(
        choices=['Toyota', 'Volvo', 'Ford'],
        form_field__show=True)  # Display this field in the simple style GUI
    model = Variable.text()

def cars(request):
    query = CarQuery()
    cars_query_set = query.request_to_q(request)
    form = query.form()
    return render(
        template_name='cars.html',
        context_instance=RequestContext(request, {'query_form': form, 'cars': cars_query_set}))

<!-- cars.html -->
{% include "tri_query/form.html" with form=query_form %}

<ul>
    {% for car in cars %}
        <li>{{ car }}</li>
    {% endfor %}
</ul>

After switching to the advanced mode:

Programmatically call the search API:

query = CarQuery()
cars_query_set = query.parse('make=Toyota and (make=1991 or make=1992)')

You need tox installed then just make test.
