Re: Dynamically calculate distance > feasible with haystack?

Ok, so got further and at least it is working.  If anyone has any improvements to suggest, would be most welcome!

class OrganizationSearchView(FacetedSearchView, ):

    """

    Faceted browsing for organizations.

    """

    

    def __name__(self): 

        return "OrganizationSearchView" 

    def __init__(self, *args, **kwargs):

        super(OrganizationSearchView, self).__init__(*args, **kwargs)

        self.searchqueryset = SearchQuerySet().models(Organization).filter(client=True).facet('industry').facet('address_country')

        

        self.form_class=FacetedBrowserForm

        self.template='search/organizationsearch.html'

    def get_results(self):

        sqs = super(OrganizationSearchView, self).get_results()

        try:

            pnt = self.request.user.get_profile().location

            sqs = sqs.distance('location', pnt)

            sqs = sqs.order_by('distance')

        except:

            sqs.order_by('registration_date')

        

        return sqs

Hey!

First, thanks for a fantastic module!

I was hoping to use haystack for implementing a faceted browser, but one of my main requirements is that I should be able to sort by distance.  The use case is fairly straightforward: I have a set of places (which have a Point) and a logged in user (which also has a Point in the userprofile).  Depending on which user is currently logged in, I would like to calculate the distance from the Point of the user to each of the places in the set.

Is this feasible?  Using Geodjango, this is a no-brainer, but not sure about Haystack (as this is based on indexing?)

In order to play with this, I was trying to place the searchqueryset definition in the view (as there we have self.request.user), but did not manage to get that working yet by the way.  Am I missing something obvious for this?

And for ref., using Solr as backend.

Thanks!
