We are going to allow users to bookmark images from external websites. The user will provide the URL of the image, a title, and optional description. Our application will download the image and create a new Image object in the database.
Let's start by building a form to submit new images. Create a new forms.py file inside the images application directory and add the following code to it:
from django import forms
from .models import Image
class ImageCreateForm(forms.ModelForm):
class Meta:
model = Image
fields = ('title', 'url', 'description')
widgets = {
'url': forms.HiddenInput,
}As you can see, this form is a ModelForm built from the Image model including only the title, url, and description fields. Our users are not going to enter the image URL directly in the form. Instead, they are going to use a JavaScript tool to choose an image from an external site and our form will receive its URL as a parameter...
