Create an integer field with a drop down box. Django Custom Widget?

I am trying to create an integer field connected with a drop down box to collect a time period from a user. From there i would like to store it in a table in some sort of readable format for the machine e.g 12W from that i can split the object and add 12 weeks on to todays date and fill a Due Date field.

For example

[12][Days]
    [weeks]
    [Months]

Would this be a customer widget? or is there a better way of completed it?

INT_CHOICES = [(x, x) for x in range(1, 60)]

in the model:

date_interval = models.PositiveIntegerField(choices=INT_CHOICES, default=1)

in the model form:

class SomeForm(forms.ModelForm):
class Meta:
    model = MyModel
    fields = ['x1', 'x2'..., 'date_interval']
    widgets = {'date_interval': forms.Select(choices=INT_CHOICES)

and that should do the trick.

I am a little surprised that the "forms.ChoiceField" in the answer above can works. See how to use forms choicefield inside modelform.

If you want just a form you could use 2 form fields, both of which are already present in Django, and their default widgets.

IntegerField (forms) + ChoiceField (forms) with choices something like [[0, "Days"],[1, "Weeks"],[2, "Months"],]

So it would look like:

class MyForm(forms.Form):
    amount = forms.IntegerField(label='Your name')
    units = forms.ChoiceField(choices=[[0, "Days"],[1, "Weeks"],[2, "Months"],])

If you want a model to store these 2 values separately, you could use (IntegerField (models) and some field of your preference with choices). Then use a ModelForm, so you will not need to define any fields on your form anymore.

In case you want even more machine-frieldly format than 2 separate values... Check whether your database can store intervals and consider using DurationField. However you will lose the possibility to automatically create neat form with 2 widgets.
