A question on lists and sorting, to prepare for a template
I have a views code that produces a dictionary like the one below, and
I want to get them in order in accordance to the keys within the
dicts; how can one do that?
Example:
{'Breakfast':[{'day':'1', 'main_course':'pancakes', 'beverage':'milk'},
{'day':'3', 'main_course':'cereal', 'beverage':'orange_juice'},
{'day':'2', 'main_course':'waffles', 'beverage':'milk'}], 'Supper':
[{'day':'1', 'main_course':'spaghetti', 'beverage':'water'},
{'day':'2', 'main_course':'pork_chop', 'beverage':'water'},
{'day':'3', 'main_course':'grilled_cheese', 'beverage':'water'}]}
In this dictionary, I am not worried if breakfast and supper are not
in order, but I do care if the days are not ordered, as I am putting
them into a script that "branches out" information, like a treeview.
Is it possible to do what I want to do?

Need a little more help with for loops
When I use the below code, the first item is "treed" like it is
supposed to be. However, when I try to put in additional branches at
the same "level", the information from the previous loops stays, thus,
when a new branch is looped, it will contain information of all
branches before it.
Here's a truncated version of the dictionary:
##
switch_info = {'Router': {'1': {'av_ports': [], 'serial':
'XXX', 'model':
'WS-SVC-FWM-1', 'ports': '6', 'card': 'Firewall Module'}, '9':
{'av_ports': [{'status': 'disabled', 'description': ' ', 'duplex':
'full', 'type': 'No Connector', 'VLAN': '1', 'speed': '10G', 'port':
'Te9/1'}, {'status': 'disabled', 'description': ' ', 'duplex':
'full', 'type': 'No Connector', 'VLAN': '1', 'speed': '10G', 'port':
'Te9/2'}], 'serial': 'XXX', 'model': 'WS-X6708-10GE', 'ports':
'8', 'card': 'CEF720 8 port 10GE with DFC'}}, 'Switch': {'1':
{'av_ports': [{'status': 'notconnect', 'description': ' ', 'duplex':
'full', 'type': 'No X2', 'VLAN': '1', 'speed': '10G', 'port':
'Te1/1'}, {'status': 'notconnect', 'description': ' ', 'duplex':
'full', 'type': 'No X2', 'VLAN': '1', 'speed': '10G', 'port':
'Te1/2'}, {'status': 'inactive', 'description': ' ', 'duplex':
'full', 'type': 'No Gbic', 'VLAN': '1', 'speed': '1000', 'port':
'Gi1/3'}, {'status': 'inactive', 'description': ' ', 'duplex':
'full', 'type': 'No Gbic', 'VLAN': '1', 'speed': '1000', 'port':
'Gi1/4'}, {'status': 'inactive', 'description': ' ', 'duplex':
'full', 'type': 'No Gbic', 'VLAN': '1', 'speed': '1000', 'port':
'Gi1/5'}, {'status': 'inactive', 'description': ' ', 'duplex':
'full', 'type': 'No Gbic', 'VLAN': '1', 'speed': '1000', 'port':
'Gi1/6'}], 'serial': 'XXY', 'model': 'WS-X4516-10GE', 'ports':
'6', 'card': 'Sup V-10GE 10GE (X2), 1000BaseX (SFP)'}}}
#
and here is the template code:

function treeInit() {
tree = new YAHOO.widget.TreeView("treeDiv1");
var root = tree.getRoot();
{% for switches in switch_info %}
var tmpNode = new YAHOO.widget.TextNode("{{switches}}", root,
false);
{% for key, value in switch_info.Router.items %}
var tmpNode1 = new YAHOO.widget.TextNode(" {{value.card}}",
tmpNode, false);
{% for item in value.av_ports %}
var tmpNode2 = new YAHOO.widget.TextNode("{{item.port}}
{{item.duplex}}", tmpNode1, false);
{% endfor %}
{% endfor %}
{% endfor %}
{% for key2, value2 in switch_info.Switch.items %}
var tmpNode1 = new YAHOO.widget.TextNode("{{value2.card}}",
tmpNode, false);
{% for item in value2.av_ports %}
var tmpNode2 = new YAHOO.widget.TextNode("{{item.port}}
{{item.duplex}}", tmpNode1, false);
{% endfor %}
{% endfor %}
tree.draw();
YAHOO.util.Event.addListener(window, "load", treeInit);
}
{% block content %}
I had to modify it so that the first loop was isolated from the other
loops, but I'm still not sure why these loops do not do the same thing
as the code in the original post.
Anyway, is it possible to make a clean slate for every "branch", or is
there a hiccup in the for loops that can be fixed?

Re: Multiple for loops, alternating between key and value?
Thanks, Russ! Your solution worked fine, however, the format that I
will ultimately be given is different than the one I gave you, with it
being mostly dictionaries, rather than lists. Thankfully, I was able
to figure out the loops enough to get the structure nearly correct,
except for one thing.
When I use the below code, the first item is "treed" like it is
supposed to be. However, when I try to put in additional branches at
the same "level", the information from the previous loops stays, thus,
when a new branch is looped, it will contain information of all
branches before it.

Multiple for loops, alternating between key and value?
Hi all, first time poster, beginner Django user.
RIght now, I'm trying to build a page that telnets into two or more
switches, gathers the data from each switch, and puts the information
into a palatable form. I managed to get the information into a format
that I think is acceptable; a list of dictionaries that have
dictionaries with lists in them.
Here is a very slimmed down version of it, as the original would fill
too much space:
switch_info = [{'Router':[{'module':'1', 'type':'RJ45', 'av_ports':
[{'port':'fa1/1', 'duplex':'auto'}, {'port':'fa1/2',
'duplex':'auto'}]}, {'module':'2', 'type':'RJ45', 'av_ports':
[{'port':'fa2/1', 'duplex':'auto'}, {'port':'fa2/2',
'duplex':'auto'}]}]}, {'Switch':[{'module':'1', 'type':'RJ45',
'av_ports':[{'port':'fa1/1', 'duplex':'full'}, {'port':'fa1/2',
'duplex':'auto'}]}, {'module':'2', 'type':'RJ45', 'av_ports':
[{'port':'fa2/1', 'duplex':'auto'}, {'port':'fa2/2',
'duplex':'auto'}]}]}]
If you were to organize that better, you'd see that there are two
dictionaries within a list, Router and Switch. Each of those
dictionaries have a list of two dictionaries, comprised of module
information. And THOSE module dictionaries have a key that has a list
of information for each port. Rather complex, as you can see.
However, I want to use a treeview script that yahoo provides, and in
order to get all that information into the script, I will have to use
for loops.
I've gotten far enough to the point that the port information and
module information branch out correctly, but the two roots of the tree
are a problem. The roots are supposed to be the keys, Router and
Switch. However, all I've gotten so far is the actual dictionaries.
So, I want it to look like this:
###
-Router
||
|-1, RJ45
| ||
| |-fa1/1, auto
| ||
| |-fa1/2, auto
| |
| +2, RJ45
|
+Switch
Instead, it looks like this:
-{'Router': [{'av_ports': [{'duplex': 'auto', 'port': 'fa1/1'},
{'duplex': 'auto', 'port': 'fa1/2'}], 'type': 'RJ45', 'module': '1'},
{'av_ports': [{'duplex': 'auto', 'port': 'fa2/1'}, {'duplex': 'auto',
'port': 'fa2/2'}], 'type': 'RJ45', 'module': '2'}]}
| |
| 1, RJ45
|| |
|| |
|| fa1/1, auto
|| |
|| |
|| fa1/2, auto
||
|2, RJ45
|
+{'Switch': [{'av_ports': [{'duplex': 'full', 'port': 'fa1/1'},
{'duplex': 'auto', 'port': 'fa1/2'}], 'type': 'RJ45', 'module': '1'},
{'av_ports': [{'duplex': 'auto', 'port': 'fa2/1'}, {'duplex': 'auto',
'port': 'fa2/2'}], 'type': 'RJ45', 'module': '2'}]}
##
And here's the code within the template:
#
The code for the javascript tree can be found here:
http://developer.yahoo.com/yui/treeview/
var tree;
function treeInit() {
tree = new YAHOO.widget.TreeView("treeDiv1");
var root = tree.getRoot();
{% for switches in switch_info %}
var tmpNode = new YAHOO.widget.TextNode("{{switches|}}", root,
false);
{% for row in switches.Router %}
var tmpNode1 = new YAHOO.widget.TextNode("{{row.module}},
{{row.type}}", tmpNode, false);
{% for item in row.av_ports %}
var tmpNode2 = new YAHOO.widget.TextNode("{{item.port}},
{{item.duplex}}", tmpNode1, false);
{% endfor %}
{% endfor %}
{% for row in switches.Switch %}
var tmpNode1 = new YAHOO.widget.TextNode("{{row.module}},
{{row.type}}", tmpNode, false);
{% for item in row.av_ports %}
var tmpNode2 = new YAHOO.widget.TextNode("{{item.port}},
{{item.duplex}}", tmpNode1, false);
{% endfor %}
{% endfor %}
{% endfor %}
tree.draw();
###
Is there any possible way to have the first loop just display the key?
