Re: "django.db.models.query.QuerySet" vs "django.db.models.QuerySet"

[Tim Graham]

Either way is okay; the original location isn't deprecated. I'd use the 
"convenience" import in django.db.models if it were me.

upload zip or rar files

[dk]

I set up a form to upload files,  and every thing works fine,   the only 
problem is when I am in the webpage and I click the button to choose the 
file I want to upload doesn't show or zips, or rars.  I try playing with 
the input tag accept, from all the type of zips,  to leave it open to 
upload what ever file.

I try it in Firefox, chrome and IE,   I am missing something?

"django.db.models.query.QuerySet" vs "django.db.models.QuerySet"

[Ilya Kazakevich]

In Django 1.6 it QuerySet was in package "django.db.models.query.QuerySet". 
But since 1.7 it also may be imported with "django.db.models.QuerySet".

Is "django.db.models.query.QuerySet" deprecated since 1.7? What is the 
"official" way to import QuerySet? I can't find any documentation regard 
this subject.

It's probably because of the ',' at each line end.
I think genus_id became a tuple of fields, remove them and try again :)

Much thanks for responding to my cry for help!  I will make the 
suggested changes and correctionns. Thanks much.


Actually, I did adhere  to Django's typical  workflow as you hinted to:

python manage.py  makemigrations 
python manage.py migrate

But when I examined the 0001_initial.py file in the migrations folder:



from django.db import models, migrations


class Migration(migrations.Migration):

dependencies = [
]

operations = [
migrations.CreateModel(
name='ActiveContracts',
fields=[
('id', models.AutoField(serialize=False, verbose_name='ID', 
primary_key=True, auto_created=True)),
],
),
migrations.CreateModel(
name='AddressBook',
fields=[
('id', models.AutoField(serialize=False, verbose_name='ID', 
primary_key=True, auto_created=True)),
],
),
migrations.CreateModel(
name='Agents',
fields=[
('id', models.AutoField(serialize=False, verbose_name='ID', 
primary_key=True, auto_created=True)),
],
),
migrations.CreateModel(
name='ArchivedContracts',
fields=[
('id', models.AutoField(serialize=False, verbose_name='ID', 
primary_key=True, auto_created=True)),

),
migrations.CreateModel(

Re: Platform.sh alternative for Django?

[Aaron C. de Bruyn]

Heroku is another paid alternative.

For myself, I purchase a $5/mo digital ocean server and install
'dokku' (https://github.com/progrium/dokku) so I can 'git push'.

For automated builds I use Drone CI (https://github.com/drone/drone)
which can also be installed on the same (or a separate) server.

If you need more and more resources as things grow (Redis, Postgres,
MySQL, etc...) you can either spin up additional cheap servers, or
'grow' your existing servers.

Django inlineform not adding cinema field info on save

[drifter]

I have a inline form which looks like the snapshot above but when I save 
the "Cinema, Movie type and Price" doesn't get added to the additional 
fields (each starts time is another instance of the field). For example the 
second line with 2015-10-02 Cinema2 will only be saved on the instance of 
Show 11:00so it only saves on the first instance.

This is the model Show:

class Show(models.Model):

MOVIE_TYPES = (
('2', '2D'),
('3', '3D'),
)

CINEMAS = (
('C1', 'Cinema 1'),
('C2', 'Cinema 2'),
('C3', 'Cinema 3'),
('C4', 'Cinema 4'),
)

movie = models.ForeignKey('Movie', related_name='shows')
venue = models.ForeignKey(Venue)
old_details = models.TextField(blank=True, editable=False,)
starts = models.DateField(db_index=True,)
starts_time = models.TimeField(db_index=True,)
couple_price = models.IntegerField(blank=True, null=True)

Re: Admin: Unknown fields

[Gergely Polonkai]

Hello,

I suspect you didn't make/run migrations:

python manage.py makemigrations
python manage.py migrate

The first command creat the so-called migration files that are required to
update the database by adding new tables and fields, while the second one
does the actual upgrade.

Also, allow me some comments.

You may want to omit genus_id from your model, as it gets created
automatically anyway. One field less to manage while you write your code.
Of course, it's up to you.

The second one is your choice field. By convention, Django people do it
this way:

EXAMPLE_CHOICES = (
('short code to store in DB', 'long text to display'),
…
)
field = models.CharField(choices=EXAMPLE_CHOICES)

My main point here other than conventions is that "short code" won't get
displayed for the user, so make your choice list based on this.

Third, eggplant is Solanum if I recall well :)

Best,
Gergely
