Keys method with (dotted=True) gives multiplication of the same key

[aviveh21]

Bug of keys in Box:

When you use keys() method in a "dotted" situation, meaning we have a tree of keys in a Box, and you want to get the keys of a given node, one can notice that we get back a list of keys that are multiplicated if the value of a key is a list. (and the multiplication is by the lengh of the list)

For example:

 

b = Box({
"Animals" : {"Land_animals" : ["Lion", "Elephant"], "Sea_animals" : ["Dolphin", "Shark"]},
"Trees" : ["Palm_tree", "Coconut_tree"]
}, box_dots = True)

 

When you are using keys = b.keys(dotted = True) you get -

['Animals.Land_animals[0]',
'Animals.Land_animals[1]',
'Animals.Sea_animals[0]',
'Animals.Sea_animals[1]',
'Trees[0]',
'Trees[1]']

and we can see the multiple occurances of the keys (with indexes of their number of values), and the method len(keys) would have wrong answer - 6 instead of 3.

The output which I thought would be right is: ['Animals.Land_animals', 'Animals.Sea_animals', 'Trees']

 

A workaround is to add to the box this:

box_intact_types = (tuple,list)

so that lists wouldn't be converted, and than it works fine.

This is actually working as intened to allow you to go recursivly through Box or BoxLists as well. For example:

from box import Box

b = Box({
"Animals" : {"Land_animals" : ["Lion", "Elephant"], "Sea_animals" : ["Dolphin", "Shark"]},
"Trees" : [{"name": "Palm_tree"}, {"name": "Coconut_tree"}]
}, box_dots = True)

print(b.keys(dotted=True))
#   ['Animals.Land_animals[0]', 'Animals.Land_animals[1]', 
#    'Animals.Sea_animals[0]', 'Animals.Sea_animals[1]', 'Trees[0].name', 'Trees[1].name']

for key in b.keys(dotted=True):
    print(b[key])

Shows:

Lion
Elephant
Dolphin
Shark
Palm_tree
Coconut_tree
