Hello,
I am really struggling with the forms in django. Its very nice that we
get simple forms, including validation, for free, but we don't seem to
get anything else. I understand that it is possible to write a custom
manipulator, but it is completely undocumented, and I'm struggling with
getting one working. What's more, I can't see any way to make a custom
manipulator dynamic at all. That is, I'd like to create forms, with a
little javascript button that says "Add More Fields". I'll give an
example.
Lets say I have a photo gallery application, with these models:
class Gallery(models.Model):
def __str__(self):
return self.client+" - "+self.name
added = models.DateTimeField(auto_now=True)
name = models.CharField(maxlength=75)
description = models.TextField(null=True)
class Composite(models.Model):
gallery = models.ForeignKey(Gallery, db_column='gallery')
added = models.DateTimeField()
name = models.CharField(maxlength=75,core=True)
description = models.TextField()
fullsize =
models.ImageField(upload_to=os.path.join(settings.SITE_ROOT,settings.MEDIA_RELATIVE_PATH),height_field=True,
width_field=True)
thumbnail =
models.ImageField(upload_to=os.path.join(settings.SITE_ROOT,settings.MEDIA_RELATIVE_PATH),height_field=True,
width_field=True)
I know these models probably aren't perfect, but I'm new to this. And,
at any rate, this still gives me a good base for explaining what I'm
trying to do.
So, now, I want to make a form for adding photos to the gallery.
There's no way that I want to make my users submit one image at a time
to this gallery. In fact, I'd like to give my user the ability to add
as many (or as few) images to their gallery as they like. So, I'd like
to have a form that starts out with, say, 5 image upload forms, and
then has a little js button next to it, that adds another upload form,
to a limited point of say, 20 (but that should be variable, to my
liking, too).
Can I do this with django? I know that I need a custom manipulator.
But, I have NO idea where to start. A tutorial, or some code would be
great. I have read the django code, and its really not helping. So,
please, help me get started!
