Django administration provides three buttons for submitting the currently edited object. Each of them has a unique name and depending on the name that is sent to the server, the specific action is performed. I see this as an ugly solution and prefer to have a choice field in the form which would render as submit buttons with different values. Then the values would be checked instead of the names. Therefore, I created the `MultipleSubmitButton` widget. When `<input type="submit" value="Go" />` is used, the value sent to the server always matches the text on the button, but if `<button type="submit" value="go">Go</button>`, the value and the human representation might differ.
To use the `MultipleSubmitButton` widget, pass it to the widget parameter of a `ChoiceField` like this:
SUBMIT_CHOICES = (
('save', _("Save")),
('save-add', _("Save and Add Another")),
)
class TestForm(forms.Form):
do = forms.ChoiceField(
widget=MultipleSubmitButton,
choices=SUBMIT_CHOICES,
)
When you print `{{ form.do }}` in the template, the following HTML will be rendered:
<ul>
<li><button type="submit" name="do" value="save">Save</button></li>
<li><button type="submit" name="do" value="save-add">Save and Add Another</button></li>
</ul>
When you submit this form and check the validity of it, `form.cleaned_data['do']` will return "save" or "save-add" depending on the submit button clicked.
HTML allows an option in a <select> to be disabled. In other words it will appear in the list of choices but won't be selectable. This is done by adding a 'disabled' attribute to the <option> tag, for example:
`<option value="" disabled="disabled">Disabled option</option>`
This code subclasses the regular Django Select widget, overriding the render_option method to allow disabling options.
Example of usage:
class FruitForm(forms.Form):
choices = (('apples', 'Apples'),
('oranges', 'Oranges'),
('bananas', {'label': 'Bananas',
'disabled': True}), # Yes, we have no bananas
('grobblefruit', 'Grobblefruit'))
fruit = forms.ChoiceField(choices=choices, widget=SelectWithDisabled())
Widget for editing CommaSeparatedIntegerField with a set of checkboxes. Each checkbox corresponds to single integer value. So, choices should be pre-defined for widget.
**Example**
Assume, we need a registration form for some event with time frame for 3 days, starting at Monday. User can select any of 3 days, so we need to show 3 checkboxes.
Here's the basic example for such form:
class EventRegistrationForm(forms.Form):
days = forms.CharField(widget=NumbersSelectionWidget(
['Mon', 'Tue', 'Wed'], range(1, 4)))

- widget
