[django-users] How to dynamically set crop processor parameters in django-imagekit ?
Hi,
I am using django-imagekit to crop images.
I have this model:
*from imagekit.models import ImageSpecField*
*from imagekit.processors import Crop*
*class Image(models.Model):*
*x1 = models.IntegerField(blank=True, default=0)*
*y1 = models.IntegerField(blank=True, default=0)*
*height = models.IntegerField(blank=True, default=0)*
*width = models.IntegerField(blank=True, default=0)*
*image_file = models.ImageField(upload_to='images/')*
*
*
*cropped_image = ImageSpecField(*
*[Crop(width=171, height=82, anchor=None, x=-224, y=-283)],*
*image_field='image_file',*
*format='JPEG', options={'quality': 90})*
How can I use the object's attributes x1, y1, width and height as
parameters to Crop processor ?
Regards,

Re: [django-users] Error when registering a new user - Django 1.5
I did it and aparently it worked:
*# forms.py*
*class UserCreateForm(UserCreationForm):*
*
*
*
def clean_username(self):
username = self.cleaned_data["username"]
try:
self._meta.model._default_manager.get(username=username)
except self._meta.model.DoesNotExist:
return username
raise
forms.ValidationError(self.error_messages['duplicate_username'])
*
*
*
*class Meta:*
*model = get_user_model()*
*fields = ('email', 'password1', 'password2', 'first_name',
'last_name', 'bio', 'username')*
*
*
From:
https://groups.google.com/forum/?fromgroups=#!topic/django-users/kOVEy9zYn5c
Should not it be the UserCreationForm standard?

[django-users] Error when registering a new user - Django 1.5
Hi,
I am getting an error when registering a new user in a Django 1.5 app.
It is the postgres' log:
*BRT ERROR: relation "auth_user" does not exist at character 280*
*BRT COMMAND: SELECT "auth_user"."id", "auth_user"."password",
"auth_user"."last_login", "auth_user"."is_superuser",
"auth_user"."username", "auth_user"."first_name", "auth_user"."last_name",
"auth_user"."email", "auth_user"."is_staff", "auth_user"."is_active",
"auth_user"."date_joined" FROM "auth_user" WHERE "auth_user"."username" =
E'teste'*
*
*
My code is very simple:
*
*
*# models.py*
*class User(AbstractUser):*
*bio = models.CharField(max_length=255, blank=True, null=True)*
*objects = UserManager()*
*# forms.py*
*class UserCreateForm(UserCreationForm):*
*class Meta:*
*model = get_user_model()*
*fields = ('email', 'password1', 'password2', 'first_name',
'last_name', 'bio', 'username')*
*# views.py*
*class UserCreateView(CreateView):*
*form_class = UserCreateForm*
*model = get_user_model()*
*
*
I think that UserCreationForm yet search for auth_user table.
A possible solution would be this:
*# models.py*
*class User(AbstractUser):*
*bio = models.CharField(max_length=255, blank=True, null=True)*
*objects = UserManager()*
*class Meta:*
* db_table = u'auth_user'*
But i would like to use a correct Django 1.5 approach to register a new
user.
Can anyone spot the problem?
Regards,
Leonardo

Re: define form in yaml file
