[Facebooker-talk] view problem

[kevin lochner]

I was wrong, it's not just in the view, it's a problem in the  
controller as well.

This may be considered a bug - if the user location is empty, the  
object returned by user.location is a string,
so calling user.location.city throws an exception.

In my controller I iterate over users with the following:

 > friends.each do |f|
 >   logger.warn "class: #{f.current_location.class}"
 >   logger.warn "location: #{f.current_location}"
 >    if f.current_location
           logger.warn "city: #{f.current_location.city} \n"
 >    end
 > end

and I get the following output:

 >class: Facebooker::Location
 >location: #<Facebooker::Location:0x7fe614b68eb8>
 >city:

 >class: Facebooker::Location
 >location: #<Facebooker::Location:0x7fe614b67b58>
 >city: Ann Arbor

 >class: String
 >location:
 > NoMethodError (undefined method `city' for "":String):

and for verification i dumped the hash from which the user was  
populated:
 > nameJeff  
SmithuidXXXXXlocaleen_USfirst_nameJeffcurrent_locationlast_nameSmith
