Re: Django 1.8 data migrations not able to locate related collections

[Pavel Kuchin]

Hi A Lee,

Can't say for sure but probably it is because your related_name is not 
unique in core/migrations/0001_initial.py 
(https://github.com/virtualcommons/vcweb/blob/develop/vcweb/core/migrations/0001_initial.py#L647,
 
https://github.com/virtualcommons/vcweb/blob/develop/vcweb/core/migrations/0001_initial.py#L208)
 
And based on django documentation the related_name must always be unique 
(https://docs.djangoproject.com/en/1.8/topics/db/models/#be-careful-with-related-name)

It is just an assumption.

Yours sincerely,
Pavel

Well then why do you get it from socket.gethostname() ? Just set it to 
‘localhost’.

Re: Error : socket.gaierror: [Errno -5] No address associated with hostname

 socket.gethostname()

Return a string containing the hostname of the machine where the Python 
interpreter is currently executing ie in python documentation
so ie used gethostname()

Re: Error : socket.gaierror: [Errno -5] No address associated with hostname

[François Schiettecatte]

I know what socket.gethostname() does, we still dont know what it returns on 
your setup. And the exception you get is about the host name. Note that a host 
can have multiple host names and socket.gethostname() only returns one, which 
may not be the one you want to use. By default a machine will have the host 
name ‘localhost’ which is a loopback, but it may have others if it is part of a 
network.

managed=False ignored by migrate

[Drew Ferguson]

Hi

Trying to use a legacy database with Django
1.8 (specifically Django-1.8-py2.py3-none-any.whl with python2.7)

I followed the steps in
https://docs.djangoproject.com/en/1.8/howto/legacy-databases/

i.e. "python manage.py inspectdb" and tidyup the resulting models file

However when I run "python manage.py migrate" it insists on trying to
create one of the tables; since the table already exists, it crashes
leaving the django tables incorrectly built so I cannot start
django at all i.e. "django_session" does not exist

In a previous iteration I had django running fine but it always wanted an
"id" field to exist in tables even though there was another field had
"primary_key=True" set

Is there some trick I am missing or maybe I should not be using 1.8 just
yet

Re: managed=False ignored by migrate

Erk!

My own fault unfortunately, apologies for the noise

Some files had gotten left in a migration folder in an app; causing all
sorts of confusion evidently

All well now...

Difficulty in using windows azure blob services for my project !!

[livelikehimanshu12]

Hello friends !!
So my project requires me to store images on blob service of windows azure 
.I am using django in visual studio express . I even have an azure account..
So I wrote the code using a lot help from internet (I was total beginner to 
django when I started this project ) . My code works perfectly fine for 
django admin interface i.e. my images are getting stored on azure blobs 
online and using the stored URL(in my models field) I am able to access it 
also.
I followed this url   https://pypi.python.org/pypi/azurepython3/1.7.7

But the problem comes when I am creating my own form which will take image 
As input from user and upload it to my account's blob service !
The image is not getting stored !! I don't know what's wrong with my code !!
It was working well when I was working with django default filesystem .The 
same models.py works for admim interface but for my normal GUI it is not 
working !!

One more thing , I created my form as we do in normal HTML and I am not 
using django form class !!
Plzz help me !! I am totally stuck .
I am a newbie in django !!

This isn't how to handle uploaded files - file data is stored in
request.FILES. There is a section in the documentation explaining the
simple file upload case, see here:

https://docs.djangoproject.com/en/1.8/topics/http/file-uploads/#basic-file-uploads

You would be well advised to use a ModelForm to process data that you
post to a view in order to create items:

https://docs.djangoproject.com/en/1.8/topics/forms/modelforms/#module-django.forms.models

and use an ImageField to process the file:

https://docs.djangoproject.com/en/1.8/ref/forms/fields/#imagefield

Cheers

Tom

Hi A Lee,

I think I've seen that one before. Can you check if the fix 
for https://code.djangoproject.com/ticket/24573 resolves the issue?

DurationField with default value

[Mathijs Jonker]

Hi,

I'm trying to figure out how to use a default value with a duration field.

When I use *time_passed = models.DurationField(default=0)*:

  * Migrations work
  * Form defaults *don't* work *'int' object has no attribute
'total_seconds'*

When I use *time_passed = models.DurationField(default=timedelta())*:

  * Migrations *don't* work *ValueError: Cannot serialize:
datetime.timedelta(0)*
  * model default works

So what is the right way to use a default value on duration field or is 
this a bug?
(stackoverflow question: 
http://stackoverflow.com/questions/29699857/django-durationfield-default-value)

With kind regards,
mjonker

"RuntimeError: Error creating new content types."

[Christophe Pettus]

On Django 1.8, I'm encountering this error when attempting to apply migrations 
on the production system.  What's interesting is that it works fine on the dev 
system, and inspecting the django_migrations table, I don't see any 
(meaningful) differences between them (error text below).

There was a model added to the "catalog" application which is not being created 
in django_content_type.

Manually migrating contenttypes individually generates the same error.

Re: "RuntimeError: Error creating new content types."

[Christophe Pettus]

Digging into this a bit more, the specific exception is that it is trying to 
insert a contenttypes row with a null 'name' value.

The code in question is doing a get_or_create() on the contenttype object.  I 
assume it should be picking up the name from the name @property on the 
ContentType model, but I don't see that ever actually being called.

Re: annotate() questions

[Carsten Fuchs]

Hi Ramiro,

Am 2015-04-16 um 19:30 schrieb Ramiro Morales:

https://docs.djangoproject.com/en/1.8/topics/db/aggregation/#aggregations-and-other-queryset-clauses

"...When used with an annotate() clause, a filter has the effect of
constraining the objects for which an annotation is calculated. For
example..."

e.g.::

Store.objects.filter(books__pubdate__year=2014).annotate(min_2014_price=Min('books__price'),
max_2014_price=Max('books__price'))



That's a very good info, many thanks for pointing me there!

Initially I thought that this would only limit/filter the Store objects 
that are annotated ("a filter has the effect of constraining the objects 
for which an annotation is calculated"), but the subsequent section 
https://docs.djangoproject.com/en/1.8/topics/db/aggregation/#order-of-annotate-and-filter-clauses 
clearly (in hindsight) explains that it, in this order, effectively 
filters the book objects that are used for the annotation as well.


Now if only I knew how to obtain the actual book objects related to the 
min/max prices...


Many thanks and best regards,
Carsten

Re: "RuntimeError: Error creating new content types."

[Tim Graham]

The contenttypes name column was removed in Django 1.8. Could you retrieve 
the underlying exception before the RuntimeError is raised?

It's a bug that Django cannot serialize timedelta objects in migrations. It

Re: "RuntimeError: Error creating new content types."

[Christophe Pettus]

Well, django_content_type.name definitely in my database. :)  This is a project 
that was migrated from 1.6.

The underlying exception was a null value complaint about 
django_content_type.name; it appears as though (on the production database) it 
thought that the migration to remove had been applied, but in fact had not been.

Should squashmigrations produce a migration that could be improved by editing?

[Andrew Farrell]

Hi Folks,

I recently squashed 93 migrations down to 1 in order to improve the speed
at which tests ran. (5 tests took about 70 seconds to run before. Now they
take 13.) I noticed that the resulting migration had a large list of small
operations, mostly migration.AddField. What I have two questions:

1) Is it likely worth the effort to decrease the time it takes for the test
runner to spin up the test database by pushing these operations into just a
few and are there any tripwires I should be aware of in doing so?

2) I did need to re-order two CreateModel operations in order to get this
migration to run because a model was created before one on which it had a
ForeignKey relation. I suspect this of being a bug someone would have run
into already but a couple

 searches

show
one hasn't been filed don't turn up anything. Does this sound familiar to
anyone or should I file a new ticket?


This project is currently running
python=2.7.9
django==1.7.7

cheers,
Andrew

Re: Django 1.8 data migrations not able to locate related collections

[A Lee]

Hi Markus, thanks for the fast response! Yup, that did the trick. I had to
do some manual copypasta into the stable/1.8.x branch to get it to run but
it appears that was the issue.

Implementing a timeline of objects

[Vibhu Rishi]

Hi Folks,

I am playing around with Django and making a site for my motorcycling
group.

I am trying to implement a timeline view and thought I would share my
thoughts with you and get some feedback.

So far, I have a few models which can be user created. A user can add a
'bike' , or a 'place' or add 'tips' to the place. Now, I want this all to
be shown in a single flow on a page. Lets say the URL for this is
/timeline.

I am trying to figure out which is the best way to aggregate this data. So,
far I have been thinking of the following :
1. Create another object, which I can call "timeline" object, and when the
save for any of the above objects is called, I also create a 'timeline'
object, and populate with the pk and a choice_field item for the 3 models.
I don't particularly like this as if I want to add a new object, I will
need to make changes to multiple places.
2. I create a base model from which I derive these models. There are a few
common fields for the timeline view which create the base model. However, I
don't know how i can differentiate between the different model types when I
implement the view & Template.
3. If there is a way to chain the objects together in a view. In this case,
I don't have to change my current code much - but I could not figure out if
this can be implemented.  Essentially, i do a get on the different models
into a meta model , sort them by creation timestamp and render in the view.

What are your thoughts ?
