- if (typeof(person) == 'undefined')
    input(type="text", name="person[Name]")
  - else
    input(type="text", name="person[Name]", value="#{person.Name}")

Is there any way to write this inline? I have an option select and I don't want to do a conditional statement for 30+ values to select the right option.

You could use mixins

mixin safeInput(person, property)
  - if (typeof(person) == 'undefined')
    input(type="text", name="person[#{property}]")
  - else
    input(type="text", name="person[#{property}]", value="#{person[property]}")

Then

mixin safeInput(person, 'Name')
mixin safeInput(person, 'Email')
...

conditional statement should do

input(type='text', name='person[Name]', value= (person?(person.name?person.name:''):''))

however, by design we can always pass a person? this way there is no parison required. Code would be something like

input(type='text', name='person[Name]', value= person.name)

You can short circuit as follows:

input(type="text", name="person[Name]", value="#{person && person.Name}")

When the value is undefined or null, the attribute will not be shown. This should work:

input(type='text', name='person[Name]', value= person && typeof(person))
