Hi, I''m trying to use number_to_currency in one of my models, but i''m getting the following error: undefined method `number_to_currency'' for #<Product:0x396d680> Obviously, my Product model can''t access number_to_currency -- is there something I need to do to make it available? Thanks so much for your assistance. -- Posted via http://www.ruby-forum.com/.
The "number" helpers are only available in your view.

As previously stated, those are view helpers. Models really shouldn''t have any formatting data in them at all... your view layer should do that for you. But explain why you want to do number_to_currency in the model (remember this renders a string) and there may be a way to solve your problem. You *can* get number_to_currency working in the model -- I''ve done it before but it''s not a good approach.

I have a Product model with min_price and max_price properties. In many places throughout the site, I need to display a price range. I had this in my application_helper: def get_price_range(min,max) if min == max price_range_text = number_to_currency(max) else price_range_text = number_to_currency(min)+ '' - '' + number_to_currency(max) end end But I thought it would be nice to make this an accesible value on my Product model, so in my view I could just say <%=product.price_range%> as opposed to <%=get_price_range(product.min_price,product.max_price)%> So I tried adding this to my Product Model: def price_range if self.min_price == self.max_price price_range_text = number_to_currency(self.max_price) else price_range_text = number_to_currency(self.min_price)+ '' - '' + number_to_currency(self.max_price) end end But apparently I shouldn''t be doing this? -- Posted via http://www.ruby-forum.com/.
Your helper approach is the way to go actually. That''s what helpers are
for.
But make it a little easier to use by just explicitly returning the sring at
the end of the mod
def get_price_range(model)
if model.min == model.max
price_range_text = number_to_currency(model.max)
else
price_range_text = number_to_currency(model.min)+ '' - '' +
number_to_currency(model.max)
end
price_range_text
end
Then your helper works like
<p>Price range: <%=get_price_range @product %></p>
Perfectly appropriate. Way to go.
