default text for foreign key in form in django

I know that is the simple question but I have trouble with this I have a table that shows colors and I used this as foreign key in Post table

class Post(models.Model):
    """docstring for Post"""

    user = models.ForeignKey(settings.AUTH_USER_MODEL, default=1 )
    slug = models.SlugField(unique=True)
    post_title = models.CharField(max_length=50, help_text="write about your product")
    color=models.ForeignKey(Color)
    phone=models.CharField(max_length=20)

now when I want to show the form of Post to show the first row like this in color field in form page

now I want to show choose color instead of --------.

In your model form, you can use __init__() to initialize your form. Something like:

from django import forms
from .models import Post

class PostForm(forms.ModelForm):
    class Meta:
        model = Post
        fields = ('post_title', 'color')  # fields to show in your form

    def __init__(self, *args, **kwargs):
        super(PostForm, self).__init__(*args, **kwargs)
        self.fields['color'].empty_label = "Choose color"

By default the widget used by ModelChoiceField will have an empty choice at the top of the list. You can change the text of this label (which is "---------" by default) with the empty_label attribute, or you can disable the empty label entirely by setting empty_label to None

Docs

Ex:

field1 = forms.ModelChoiceField(queryset=..., empty_label="(Choose color)")
