I'm having problems writing template for custom controls (a bootstrap
button bar) using optgroup.
the problem is that optgroup is not grouping choices without groups, this
makes very hard to create several button bars that grouped togheter:
{{{
from django.forms.widgets import ChoiceWidget
w = ChoiceWidget(choices = [
("one", 1),
("two", 2), [
"italian", (
("uno", 1),
("due", 2)
)
]
])
}}}
now see how choices are grouped from optgroup:
{{{
import json
print(json.dumps(w.optgroups("name", "one"), indent = 4))
}}}
{{{
[
[
null,
[
{
"name": "name",
"value": "one",
"label": 1,
"selected": true,
"index": "0",
"attrs": {
"checked": true
},
"type": null,
"template_name": null
}
],
0
],
[
null,
[
{
"name": "name",
"value": "two",
"label": 2,
"selected": false,
"index": "1",
"attrs": {},
"type": null,
"template_name": null
}
],
1
],
[
"italian",
[
{
"name": "name",
"value": "uno",
"label": 1,
"selected": false,
"index": "2_0",
"attrs": {},
"type": null,
"template_name": null
},
{
"name": "name",
"value": "due",
"label": 2,
"selected": false,
"index": "2_1",
"attrs": {},
"type": null,
"template_name": null
}
],
2
]
]
}}}
this means that if choices are flats (no groups) you are getting a number
of groups that is the same of the number of choices, and in order to fix
this you need to use the grouping filters on the template in order to
regroup choices.
I think this is a bug, and flat choices should be grouped together as None
by optgroup method
thanks
