[FIXED] Django admin select dropdown

Issue

I have a field in my model called day. I want in the admin area to have a pre populate dropdown for this field instead of the text input. I have search and cant find a solution.

<select name="day" id="day">
  <option value="Monday">Monday</option>
  <option value="Tuesday">Tuesday</option>
  <option value="Wednesday">Wednesday</option>
  <option value="Thursday">Thursday</option>
</select>

Model:

class Timetable(models.Model):

    gym_class = models.ForeignKey('GymClass', on_delete=models.CASCADE)
    start_date = models.DateField()
    end_date = models.DateField()
    day = models.CharField(max_length=12)
    time_slot = models.CharField(max_length=12)
    trainer = models.ForeignKey('Trainer', on_delete=models.CASCADE)

    def __str__(self):
        return self.gym_class.name

admin.py:

from django.contrib import admin
from .models import GymClass, Category, Trainer, Timetable

admin.site.register(GymClass)
admin.site.register(Category)
admin.site.register(Trainer)
admin.site.register(Timetable)

Solution

You are looking to modify ModelForm that is used in your admin. We change widget that is used by day, so instead of text <input> it will show <select>.

class TimetableForm(forms.ModelForm):
    class Meta:
        fields = '__all__'
        model = Timetable
        widgets = {
            'day': forms.Select(choices=[('Monday', 'Monday'), ('Tuesday', 'Tuesday'), ('Wednesday', 'Wednesday'), ('Thursday', 'Thursday')]),
        }


class TimetableAdmin(admin.ModelAdmin):
    form = TimetableForm


admin.site.register(Timetable, TimetableAdmin)
