Django GenericRelation not working

[arthur . muchir]

I have the following model in my app, using the content-type django 
framework in version 1.6.1 :

class GenericMedia(models.Model):
limit   = models.Q(model = 'Image') | models.Q(model = 'Video') | 
models.Q(model = 'Other')
content_type= models.ForeignKey(ContentType, limit_choices_to = limit)
object_id   = models.PositiveIntegerField()
content_object  = generic.GenericForeignKey('content_type', 'object_id')

def __unicode__(self):
return u"%s" % os.path.basename(self.content_object.url.name)

def instance(self):
return self.content_object.__class__.__name__

class Media(models.Model):
description = models.CharField(blank = True, max_length = 500)
link= models.URLField(blank = True)
genericFK   = generic.GenericRelation(GenericMedia, 
content_type_field='content_type', object_id_field='object_id')

class Meta:
abstract = True

def __unicode__(self):
return u"%s" % os.path.basename(self.url.name)

def save(self, *args, **kwargs):
super(Media, self).save(*args, **kwargs)
generic_link = GenericMedia(content_object = self)
generic_link.save()

class Image(Media):
imgW = models.PositiveSmallIntegerField()
imgH = models.PositiveSmallIntegerField()
url  = models.ImageField(upload_to = 'mediamanager', height_field = 'imgH', 
width_field = 'imgW')

Everythings works fine, excepts the GenericRelation in my abstract Media Class.

In django documentation it is said that :
If you delete an object that has a GenericRelation, any objects which have a 
GenericForeignKey pointing at it will be deleted as well.

But my problem is that when I delete an image (wich extends Media), the 
GenericMedia pointing to it is not deleted.

If anyone has a solution, thanks !

How to approach this problem?

[César García Tapia]

I'm trying to solve a problem, but I have no idea how to face it. I need 
some help :-)

I have a model hierarchy like this:

class Task(models.Model):
name = models.CharField(max_length=255)
number_of_steps = models.IntegerField()

class StepGroup(models.Model):
task = models.ForeignKey(Task)
init_date = models.DateField()

class Step(models.Model):
group = models.ForeignKey(StepGroup)
name = models.CharField(max_length=255)

I must write a dialog where I create a number of Step Groups. An 
InlineFormSet looks the way to go, but as there are two levels of nesting, 
I don't know how to do that.

Besides, I need the usual stuff with forms: error control 
(form.name_of_field.errors), autopopulation when editing the Task, etc, so 
doing it manually with javascript and server-side handling of the POST 
request would be too complicated and error-prone.

This is the way I need the form (the number of steps in each group is set 
by the "number_of_steps" field in the Task model):

+---+
| STEP GROUP 1  |
|   |
| Init date: _  |
|   |
| Step 1:   |
| Step 2:   |
| Step 3:   |
|   |
+---+
| STEP GROUP 2  |
|   |
| Init date: _  |
|   |
| Step 1:   |
| Step 2:   |
| Step 3:   |
|   |
+---+
|   |
| +---+ |
| | Create step group | |
| +---+ |
+---+

Please, any kind of help, suggestion or link will be very appreciated :-)

django 1.6 When creating superuser in cmd.exe, why ask a password for three times?

[项楠]

django 1.6.1,python 3.3.3, windows 8.

I choose Substituting a custom User 
model,
 
and everything is ok except creating superuser at the beginning:

[image: enter image description here]

As you can see, django asked password for three times despite the success 
in creating the superuser., why?

this is the source code , if needed. 
Thanks.

Re: django 1.6 When creating superuser in cmd.exe, why ask a password for three times?

[Russell Keith-Magee]

Hi,

I can't check your source code (I haven't got a baidu account, which
appears to be a requirement for downloading the zip file you've provided),
but you should only be asked for your password twice.

My guess is that you've included "password" in your list of
REQUIRED_FIELDS. REQUIRED_FIELDS only needs to include user-added fields on
your own model - for example, if ever user must have a date of birth, you
can put the date_of_birth field in REQUIRED_FIELDS. You *don't* need to
include username, password, or any of the built-in fields that Django
provides as part of the base user model. Remove 'password' from
REQUIRED_FIELDS, and you should only get two requests for a password.

I can see why you've made this error - the documentation isn't clear on
this point. I've opened ticket #21726 [1] to make sure this is addressed.

It worked. Thank you. BTW, could you recommend a site for sharing files not

Re: django 1.6 When creating superuser in cmd.exe, why ask a password for three times?

[Russell Keith-Magee]

Glad to hear you could solve your problem.

As for sharing files without needing an account; two options I can think of:

 1) Github Gists (https://gist.github.com) are useful for sharing a small
number of files, especially source code. You can also update the files,
keep track of versions, receive comments and so on.

 2) Dropbox allows you to put files into a public folder and share a URL to
that file.

Both these services will require *you* to create an account, but the person
reading/receiving your files will not.

Hope that helps!

Yours,
Russ Magee %-)

NameError "SignUpAdmin"

[Eddie29]

Hi Guys, 
I am really new to Django and Python. I have recently started learning them 
from a course on Udemy and I got stuck on the first example, making a web 
app. I'm not sure what I have done wrong but when I run my Django server it 
comes up with a NameError. I think the app is supposed to handle user data, 
such as first name,last name and email. 
Thanks in advance :)

Hi Guys,
I am really new to Django and Python. I have recently started learning 
them from a course on Udemy and I got stuck on the first example, 
making a web app. I'm not sure what I have done wrong but when I run 
my Django server it comes up with a NameError. I think the app is 
supposed to handle user data, such as first name,last name and email.
I'm not familiar with the course, and haven't tried to set up your 
project to test.


But I can recommend that you start with the Django tutorial in the 
Django docs (whichever doc version matches the version of Django you are 
using). You might then find it easier to spot small problems in other 
projects such as when you go back to your course.

Thanks in advance :)

This error is a bit of a red flag -- it means that you've got mixed Python
byte code versions. Somehow, you've generated byte code using one version
of Python, and you're then running the code using a different version of
Python.

Unfortunately, I have *no* idea how you might have caused this problem. It
looks like you're running on a Mac, so it's possible that the system is
getting confused over whether system python is Python 3 or Python 2 --
you're invoking "python manage.py runserver" at the command line and
getting Python 3, but if some quirk of your environment is causing Python 2
to be the system default somewhere, you will get problems.

My suggestion here is to make sure you're running your code in a virtualenv
[1] -- that will make sure that the "local" Python is always clear. Using
virtualenv is good practice anyway for Python development, because it
isolates the dependencies of each project from each other.
