Passing a block to gsub

Rails
1

Hello,

So I have a product description field and in that product description
field every time I have the @ symbol followed by a product id the
following method will replace the @ sign with the products permalink
in a format. The code below works.

def product_description(product)
product.description.gsub(/@(\w+)/m) do |w|
ws = Product.find_by_id("#{$1}")
%{}
end
end

However now I want to be able to be able to give it two options, the @
and the @c. the @ sign will associate it with a product id and the @c
will associate it with a category id. So I tried the following bellow
but I can only get one or the other to work, I can not get them to
work at the same time.

def product_description(product)
product.description.gsub(/@(\w+)/m) do |w|
ws = Product.find_by_id("#{$1}")
%{}
end
product.description.gsub(/@c(\w+)/m) do |w|
ws = Category.find_by_id("#{$1}")
%{}
end
end

If anyone has some suggestions I would greatly appreciate it. Thanks
in advance.

Well, I finally figured it out, might as well post it just in case
anyone else is trying to do the same thing. Below is the code.

converts @ signs into product links and category links

def product_description(product)
product.description.gsub(/@(\w+)/m) do |w|
if #{$1} =~ /p(.*)/
wp = Product.find_by_id(“#{$1}”.delete “p”)
%{}
else
wt = Taxon.find_by_id(“#{$1}”.delete “t”)
%{}
end
end
end

Pretty much what this allows me to do is I can take a text field and
automatically add links to words for example;

this is a test, this is a link to a @p30 product, and this is a
link to a @t45 category

That way it makes my admin views a little bit cleaner and eventually I
will add a rescue feature so if that product or category has been
deleted i wont have any broken links through out the site.
