将参数从模板传递到Django中的视图

Question

A Django noob here. I'm stuck with my problem regarding exporting csv in django. I'm currently successfully exporting a csv file containing all the objects(Product) in the database using this function in views.py of my Model Product.

def export_csv(request):

    response = HttpResponse(content_type='text/csv')
    response['Content-Disposition'] = 'attachment; filename="product-inventory.csv"'

    writer = csv.writer(response)
    writer.writerow(['Product Name', 'STATUS'])

    products = Product.objects.all().values_list('name', 'status')

    for product in products:
        writer.writerow(product)

    return response

This is in my template

<a class="export-btn" id="test" href="{% url 'export_csv' %}">Export</a>

And this is the url.py

url(r'^export/csv$', product_views.export_csv, name='export_csv')

The question is how can I change dynamically the Product.objects.all() in my export_csv function so that it will be equal to the product list obtained from the user using search (using request.GET in another function)?

Thanks in advance.

Answer 1

Try to add in template form:

<form method="GET" action="">
     <input type="text"  name="q" placeholder="Search">
     <input type="submit" value="Search">
 </form>

Now in view you can get search value and filter products:

search = request.GET.get('q')
products = Product.objects.filter(name__icontains=search).values_list('name', 'status')
