Undefined in front and at the end when passing a link inside a variable on Jade and Node.js

I am using express and Jade. When i pass variable that contains a link i get undefined in front and at the end of the url. What is this problem and how can i solve it?

The same problem as here : Express image upload and view in jade but it's not answered there.

Jade code:

block content
h1= title
p Your photos
#photos
img(src=#{purl})
p #{photo.title}

Rendering code

res.render('./user/show', { title: 'photos',photo: photo, purl: purl)});

purl is the variable of the link which when i console log just above the render appears as should and the photo.title appears too normally.

UPDATE

It's a JADE problem as with EJS everything works great.... Guess for a small problem i'll have to switch.. If anyone comes up with a solution, you're welcome.

First off, before res.render() add a console.log(purl);

You want to rule out that the variable is not undefined before it even reaches the Jade template.

In your jade, your image src does not need #{} around the purl variable. Try this:

img(src=purl)

You only need #{} when you are inside a text string and want to refer to javascript varaibles.

If you really wanted to, it could be written as img(src='#{purl}')

Your paragraph could also be written as:

p= photo.title

Where the = means the following is interpreted as javascript. No need for #{}.

If you wanted to mix text with the photo title using #{} works like a charm.

p #{photo.title} lorem ipsum
