unsupported format character '_' (0x5f) at index 1
django, python
Solution
Looks like you're trying to use standard C-style string interpolation, but you're missing the actual formatting characters.
template_name = "%s_%s_details.html"
Problem
I am trying to get the dynamic class name in django class based view . Here is my class . ``` class ProductDetailView(TemplateView): template_name = "%_%_details.html" def get_template_names(self,tmp_name,tmp_name2): return [self.template_name % tmp_name,tmp_name2] def get_context_data(self, **kwargs): context = super(ProductDetailView, self).get_context_data(**kwargs) platform = self.request.GET.get('platform') if platform == "AMAZON": asin = self.request.GET.get('asin') if asin: #products = amazon.search(Keywords=q, SearchIndex='All') products= amazon.lookup(ItemId=asin) template_name = self.get_template_names('amazon','product') context['products'] = products ``` I want to accees the template amazon_product_details.html . I am getting the error `unsupported format character '_' (0x5f) at index 1` while accessing the above view . I tried urlib quoting also but that also doesn't work . Please do let me know what might I am doing wrong here .
