Click button in table and redirect to same page

Question

I have a view:

class ProductList(SingleTableView):
    model = Product
    template_name = "app/product_list.html"
    table_class = ProductTable

where in every row there is a button that should perform function():

class ButtonColumn(tables2.Column):
    empty_values = list() 
    def render(self, value, record): 
        return mark_safe(f"""<a href="/link/{record.id}/"><button class="btn btn-info">link</button></a>""")

this ButtonColumn provides a button and once it is clicked:

    path("link/<int:pk>", views.LinkView.as_view(), name="link"),

And the corresponding view:

class LinkView(TemplateView):
    model = Product
    template_name = "app/product_list.html"

    def get_success_url(self):
        return reverse_lazy('product-list')

    def get_context_data(self, **kwargs):
        context = super(LinkView, self).get_context_data(**kwargs)
        function[kwargs] # <------------------
        context["table"] = Product.objects.all()
        return(context)

My problem is with the Linkview - I want it to perform function with some URL transmitted paramters and return to the former page (app/product_list.html). How can I achieve this?

Answer 1

Modify the ButtonColumn like this

class ButtonColumn(tables2.Column):
    empty_values = list() 
    def render(self, value, record): 
        return mark_safe(f"""<a href="/link/{record.id}/?price=10"><button class="btn btn-info">link</button></a>""")
# There is no need to mention these query parameter in path. 

The path will remain the same. No need to change anything.

    path("link/<int:pk>", views.LinkView.as_view(), name="link"),

In you ListView, you would use self.request.GET.get("param1", "") where param1 is the URL transmitted parameter and "" is the default value.

    def get_context_data(self, **kwargs):
        context = super(LinkView, self).get_context_data(**kwargs)
        param1 = self.request.GET.get("param1", "")
        # OR
        function(self.request.GET) # extract required params in the function
        function[kwargs] # <------------------
        context["table"] = Product.objects.all()
        return(context)

Note: Get is a dictionary

To redirect,

from django.shortcuts import redirects

# In your LinkView override get method
class LinkView(TemplateView):
    def get(self, request, *args, **kwargs)
        return redirect('some/url')
