taking this into consideration and spending what seems like for ever
scouring the internet and reading articles, even going over the tutorial
I go thris from I have come to the conclusion that it is a few things.
One:
module CommentsHelper
def nested_comments(comments)
comments.map do |comment, sub_comments|
render(comment) + content_tag(:div, nested_comments(sub_comments),
:class => 'nested_comments')
end.join.html_safe
end
end
the code should display something like this when I rendered out
comments,
before it could do comments.map
{ #<TreeNode id: 100018, name: "Stinky", ancestry: nil>
=> { #<TreeNode id: 100019, name: "Crunchy", ancestry: "100018">
=> { #<TreeNode id: 100020, name: "Squeeky", ancestry:
"100018/100019">
=> {}
}
}
}
except it doesn't, I get
{ #<TreeNode id: 100018, name: "Stinky", ancestry: nil>}
{ #<TreeNode id: 100019, name: "Crunchy", ancestry: nil>}
{ #<TreeNode id: 100020, name: "Squeeky", ancestry: nil>}
{}
So there’s something wrong with the helper even when its the same as the
example tutorial I was following
Two:
parent_id is apparently an attribute of comments, how ever in the
example I followed they did not have to assign it as a accessible
attribute, where as I do - else I get an error - plus there is no column
for parent_id - as there ins't suppose to be one, just ancestry and an
index of ancestry - which I have tripple checked
How ever with all that said the code seems to work. so I kept moving on
- One of the other issues after playing with the code is the helper
method.
if I take this:
module CommentsHelper
def nested_comments(comments)
comments.map do |comment, sub_comments|
render(comment) + content_tag(:div, nested_comments(sub_comments),
:class => 'nested_comments')
end.join.html_safe
end
end
and replace the nested_comments(sub_comments) with 'hello' I get
[commnet]
hello
[comment]
hello
So with that new information. what else should I be looking for? I have
red all the documentation I can, poured over examples, read he out put a
thousand times. I have printed out comments, I have tried different
styles such as @tasks.comments - as comments belong to tasks. and still
I am lost.
