Jade Templates - Dynamic Attributes

I want to create attributes on the fly for some html elements. In my case I'd like to set (or not) a disabled attribute according to `user.role`. So, if `user` has permission to edit some field, I do not want to put disabled attribute on the element. Otherwise, I do want it. I know that I can do this with these approaches: - Approach 1 - Use Conditionals ``` if (user.role === 1) input(type='text', name='foo') else input(type='text', name='foo', disabled) ``` - Approach 2 - Plain HTML ``` - var disabledAttr = (user.role === 1) ? "disabled" : ""; | <input type="text" name="foo" #{ disabledAttr} /> ``` Approach 1 is bad because I need to repeat some code. With Approach 2 I do not need to repeat code but I have to use plain HTML instead of Jade markup. I tried something like this: ``` input(type='text', name='foo', #{ disabledAttr} ) ``` But jade generates the following code: ``` <input type="text" name="foo" disabledattr="" /> ``` Any better idea?
