Question
I have a form that allows me to add to a multi list using js. I want to be able to post all the data in that list to my bottle server, but I am not able to get any of the data in there. How do I get all the items in my statement to be posted to server.py? How do I access this post data once it is posted?
Relevant code:

Russian@bottle.route('/saveList', method='POST')
def save_list():
forms = bottle.request.get('the_list')
print forms # returns 'None'
return bottle.redirect('/updatelist') # just redirects to the same page with a new list
list.tpl
<select multiple="multiple" id="the_list" name="the_list">
%for item in my_ list:
<option>{{item}}</option>
%end
</select>
EDIT:
I am trying to get the whole list, not just the selected values. The user adds to the multi by way of textfield, button, and JS; so I want to get all the values (or all the new values).
EDIT 2:
I used the answers provided along with some js to get the desired result:
$('.add_to_the_list').click(function (e) {
...
var new_item = $('<option>', {
value: new_item_str,
text: new_item_str,
class: "new_item" // the money-maker!
});
...
function selectAllNewItem(selectBoxId) {
selectBox = document.getElementById(selectBoxId);
for (var i = 0; i < selectBox.options.length; i++) {
if (selectBox.options[i].className === "new_item") { // BOOM!
selectBox.options[i].selected = true;
}
}
}
...
$('#submit_list').click(function (e) {
selectAllNewBG("the_list")
});
Solution
You were close; just try this instead:
all_selected = bottle.request.forms.getall('the_list')
You'll want to use request.forms and getall. request.forms returns a MultiDict, which is the appropriate data structure for storing multiple selected options. getall is how you retrieve the list of values from a MultiDict:
for choice in all_selected:
# do something with choice
or, more simply:
for selected in bottle.request.forms.getall('the_list'):
# do something with selected
OTHER TIPS
To get multiple values back use .getall. Here is the code I was able use this with.
import bottle
@bottle.route('/saveList', method='POST')
def save_list():
forms = bottle.request.POST.getall('the_list')
print forms
return bottle.redirect('/updatelist')
@bottle.route('/updatelist')
@bottle.view('index')
def index():
return {}
bottle.run()
The HTML
<html>
<body>
<form method="post" action="http://localhost:8080/saveList">
<select multiple="multiple" id="the_list" name="the_list">
<option value="1">Item 1</option>
<option value="2">Item 2</option>
<option value="3">Item 3</option>
</select>
<input type="submit" />
</form>
</body>
</html>
The output to stdout looks like:
127.0.0.1 - - [22/Mar/2014 13:36:58] "GET /updatelist HTTP/1.1" 200 366
['1', '2']
127.0.0.1 - - [22/Mar/2014 13:37:00] "POST /saveList HTTP/1.1" 303 0
127.0.0.1 - - [22/Mar/2014 13:37:00] "GET /updatelist HTTP/1.1" 200 366

First time selected two objects, second time didn't select any.
