Dropdown in Django Model

问题

I want to create a field in Django models.py which will render as a dropdown and user can select the options from there.

If I have 5 choices:

• GREEN
• BLUE
• RED
• ORANGE
• BLACK

How should I write my code in models.py and Forms.py so that the template renders it like a dropdown element?

回答1:

Specify CharField or IntegerField with choices option in your model https://docs.djangoproject.com/en/1.8/ref/models/fields/#choices and use ModelForm https://docs.djangoproject.com/en/1.8/topics/forms/modelforms/.

回答2:

From model to template :

models.py

COLOR_CHOICES = (
    ('green','GREEN'),
    ('blue', 'BLUE'),
    ('red','RED'),
    ('orange','ORANGE'),
    ('black','BLACK'),
)

class MyModel(models.Model):
  color = models.CharField(max_length=6, choices=COLOR_CHOICES, default='green')

forms.py

class MyModelForm(ModelForm):
    class Meta:
        model = MyModel
        fields = ['color']

views.py

class CreateMyModelView(CreateView):
    model = MyModel
    form_class = MyModelForm
    template_name = 'myapp/template.html'
    success_url = 'myapp/success.html'

template.html

<form action="" method="post">{% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Create" />
</form>

or to display your select field only :

{{ form.color }}
