Question

When a link is clicked ( Which is generated from a search result ) , it should take the name/primary key of that particular data to a view . I have read through the documentation of URL dispatcher , but haven’t got a concrete idea of how to pass the primary key of a certain row of a table to another view .

Any help is much appreciated .

Till now I have done this .

def that_view ( request , num) 
---view code 

search is generating a particular Url . When I click on that , the primary key should pass to this that_view to be processed to view the data .

Is this the right way to do it , if yes how exactly should I modify my urls.py and also the template that generates the data search (i.e the url) .

You might ask me to read the documentation , again and again . But I did . No help . Any code snippet of any kind ( even a link to such, and not a link to the documentation ) would help .

This is my views .

def map_search(request):
     lcount = Open_Layers.objects.all()

     form = SearchForm()
     if request.method == 'POST': 
            form = SearchForm(request.POST) 
            if form.is_valid():
            data = form.cleaned_data
                    val=form.cleaned_data['LayerName']

            a=OsmLayers()
                        b=Open_Layers()
            c=Sdr_Layer()
                        data = []
            data1=[]
            data2=[]
            data3=[]
            data1 = OsmLayers.objects.filter(Layername__icontains=val)
            data2 = Open_Layers.objects.filter(Layer_name__icontains=val)
            data3 = Sdr_Layer.objects.filter(layer_name__icontains=val)
            data.append(data1)
            data.append(data2)
            data.append(data3)  

            return render_to_response('searchresult.html', {'data':data})



        else:
            form = SearchForm()
     else:
        return render_to_response('mapsearch.html', {'form':form})

you just need to pass your “num” via the url.

in your urls.py:

(r'example_path/(?P<num>\w+)/$', that_view),

then inside your view, you can use the num variable as long as you want
