I have been reading tango_with_django tutorial, and when I managed to get to part 7, I was stucked.
When I added this code
from django.template.defaultfilters import slugify
class Category(models.Model):
name = models.CharField(max_length=128, unique=True)
views = models.IntegerField(default=0)
likes = models.IntegerField(default=0)
slug = models.SlugField(unique=True)
def save(self, *args, **kwargs):
self.slug = slugify(self.name)
super(Category, self).save(*args, **kwargs)
def __unicode__(self):
return self.name
I've got this

After I removed this code, I still get same error message while trying to do
python manage.py migrate
After I deleted database with
python manage.py flush
And entered
python manage.py migrate
I also got the same error.
What's going on?
try rolling back the migration to the previous state. Assuming this is your first migration - lets roll back to zero
python manage.py migrate category zero
slug logic can get a bit complex
despite names being different they can have the same slug
e.g.
Name: Foo Bar
Slug: foo-bar
Name: foo bar
Slug: foo-bar
Name: Foo Bar
Slug: foo-bar
Name: Foo! Bar
Slug: foo-bar
...you get the idea
you defiantly want unique slugs to make url access nice
e.g. domain.com/category/1234 (using id)
vs domain.com/category/foo-bar
have a look at AutoSlugField which will do lots of the hard work for you in terms of making unique slugs

I am very new to django(version 1.11).I am trying to make a shoppingwebsite and i am confused in creating Order model.
In here you can see my first (version 1) models.py
from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.contrib.postgres.fields import ArrayField

price = models.IntegerField(default=0)
image = models.ImageField(upload_to='product_image',blank=True)
vojood = models.BooleanField(default=False)
unique = models.CharField(max_length = 100 ,default='')
typ = models.CharField(max_length = 100 ,default='')

return self.name

arrived = models.BooleanField(default=False)
basket = ArrayField(models.CharField(max_length=300,default=''),default=list)
def __str__ (self):
return self.username
After python manage.py makemigrations when i tried to migrate the new field (arrayfield) with python manage.py migrate i got a very long error . So the last line was django.db.utils.OperationalError: near "[]": syntax errorSo i deleted the new field(arrayfield) and again i used makemigrations but the error during migrate did not change.And now i cant migrate any field with any type!
And here is my Error :

I also changed the name of array field from prds to basket but you can see in the error the name did not change !!!!! And it runs 0005_order_prds despite the last created migration is 00013_etc !
I think your problem is that you are using a SQLite database, you need to use a Postgres database - see this similar question.
I'm designing an Application where username will be an AutoIntegerField and unique.
Here's my model.
class ModelA(models.Model):
username = models.BigAutoField(primary_key=True, db_index=False)
user_id = models.UUIDField(default=uuid.uuid4, unique=True,
editable=False)
Initially, I wanted user_id to be a primary_key, but I can't create an AutoField which is not primary_key. As a result, I'd to let go off user_id as primary_key and assigned username as the primary key.
Now, when I run the migrations, it throws an error saying,
django.db.utils.ProgrammingError: operator class "varchar_pattern_ops" does not accept data type bigint

I think the issue is that you still have an old index on your username field that clashes with the new type. The db_index=False argument has no effect because primary_key=True always generates an index.
You might be able to solve this by removing primary_key=True, creating a migration, and then re-adding it and creating another migration. Alternatively, you can do it by hand by dropping and re-creating the index. If you want to go down that path, consult this answer.
If your project is still in an early stage and you don't have any valuable data, you can take the easy way out and drop any tables related to your users app or even the complete database, delete all migrations in the users app and create them from scratch.
in my case I was connecting django to postgres at localhost pgadmin
first deleted all the migrations except default one and also in the pycache
then just run python manage.py makemigrations and python manage.py migrate in your terminal
my app named mainsite
I have the table class named Weather in models.py
class Weather(models.Model):
tpr = models.CharField(max_length=5)
wet = models.CharField(max_length=5)
ur = models.CharField(max_length=5)
li = models.CharField(max_length=5)
observe_time = models.DateTimeField(default=None)
I don't want my observe_time set any deafult value
So I set to None .
I have made migrations.
when I made migrate

I don't know what caused this error.
thx.
In order for this to work you should also make this field nullable and blankable, like this:
observe_time = models.DateTimeField(default=None, blank=True, null=True)
or omit default=None completely, like this:
observe_time = models.DateTimeField(blank=True, null=True)
Also, after that, don't forget to delete the previous migration file and run makemigrations and migrate again.
here its my model code
class student(models.Model):
name = models.CharField(max_length=100)
age = models.IntegerField()
available = models.BooleanField(default=False, blank=True)
In above model available is my new field, now I want to migrate database but it give me error, when I'm run following command
python manage.py migrate
Operations to perform:
Apply all migrations: student

something wrong here please give me a solution for above problem.
I had this issue, when I wanted to change a field to be non-nullable, but there were already data in the database, where this value was null, which brought the conflict. I was able to resolve it by
Add the nullable field.
migrations.AddField(
model_name='mymodel',
name='new_field',
field=models.OneToOneField(to='app.OtherModel', null=True, default=None),
preserve_default=False,
),
Use RunPython to populate the fields of the existing data with something that made sense
migrations.RunPython(fix_null_fields)
Finally alter the field to be non-nullable
migrations.AlterField(
model_name='mymodel',
name='new_field',
field=models.OneToOneField(to='app.OtherModel'),
preserve_default=True,
),
This seemed to work for me without any trouble. For more information, look into Migrations and Migration operations
So I am using south for my django project, and have been changing some model logic. I changed a bunch of things, but regardless, my model looks like this now:
class Group(models.Model):
'''table of organizational groups'''
group_id = models.AutoField(primary_key=True)
group_name = models.CharField(max_length=100,unique=True) #name of group as string
icon_path_clicked = models.CharField(blank=True,max_length=255) #location icon is stored
icon_path_unclicked = models.CharField(blank=True,max_length=255) #location icon is stored
group_description = models.CharField(max_length=255) #description of the group
is_active = models.BooleanField(default=True)
date_created = models.DateTimeField(auto_now_add=True)
now previously, both icon_path_clicked and icon_path_unclicked had unique=True, but I took that out, yet when I try and migrate, I get the following error:
django.db.utils.IntegrityError: could not create unique index "everything_group_icon_path_clicked_key"
DETAIL: Key (icon_path_clicked)=() is duplicated.
why is it still treating this as if I no longer have that field as unique?
