bob = Trello::Member.find("bobtester")

# Print out his name
puts bob.full_name # "Bob Tester"

# Print his bio
puts bob.bio # A wonderfully delightful test user

# How about a list of his boards?
bob.boards

# And then to read the lists of the first board do :
bob.boards.first.lists

# With bob
pp bob.boards # Will pretty print all boards, allowing us to find our board id

# We can now access it's lists
pp Trello::Board.find( board_id ).lists # will pretty print all lists. Let's get the list id

# We can now access the cards of the list
pp Trello::List.find( list_id ).cards

# We can now access the checklists of the card
pp Trello::Card.find( card_id ).checklists

# and so on ...

# First get your checklist id
checklist = Trello::Checklist.find( checklist_id )

# At this point, there is no more ids. To get your checklist item,
# you have to know it's position (same as in the trello interface).
# Let's take the first
checklist_item = checklist.items.first

# Then we can read the status
checklist_item.state # return 'complete' or 'incomplete'

# We can update it (note we call update_item_state from checklist, not from checklist_item)
checklist.update_item_state( checklist_item.id, 'complete' ) # or 'incomplete'

# You can also use true or false instead of 'complete' or 'incomplete'
checklist.update_item_state( checklist_item.id, true ) # or false
