I really wish I could give some useful information in the terms of a
traceback so others may have an idea what is happening to me but I'm
completely serious when I say I don't even get a traceback right now. Here
is the break down of what I did to give an idea of how I ended up at this
point, hopefully. I will continue to try to iterate upon this discussion as
well through observations to try to work on my own or with others to get
down to the cause of the issue.
First with a clean and empty database I ran the migrate command and
everything went fine. There were no issues as it ran through:
(zcosystem)jjs-macbook-pro:athletesunited JJZ$ python manage.py migrate
*Operations to perform:*
* Synchronize unmigrated apps: *colleges, ads, debug_toolbar, comments,
communities, main, athletes, ad_manager
* Apply all migrations: *admin, contenttypes, sites, auth, sessions

Applying auth.0001_initial...* OK*
Applying admin.0001_initial...* OK*
Applying sessions.0001_initial...* OK*
Applying sites.0001_initial...* OK*
Next up I called to create a super user and that went fine as well:
(zcosystem)jjs-macbook-pro:athletesunited JJZ$ python manage.py
createsuperuser
Username (leave blank to use 'jjz'):
Email address:
Password:
Password (again):
Superuser created successfully.
Then I ran the makemigrations command for the respective apps and their
models that I wanted to have:
(zcosystem)jjs-macbook-pro:athletesunited JJZ$ python manage.py
makemigrations colleges
*Migrations for 'colleges':*
*0001_initial.py*:
- Create model College
- Create model CollegeEvent
(zcosystem)jjs-macbook-pro:athletesunited JJZ$ python manage.py
makemigrations ads
*Migrations for 'ads':*
*0001_initial.py*:
- Create model Ad
- Create model Partner
- Add field partner to ad
(zcosystem)jjs-macbook-pro:athletesunited JJZ$ python manage.py
makemigrations comments
*Migrations for 'comments':*
*0001_initial.py*:
- Create model Comment
- Create model CommentFlag
- Alter unique_together for commentflag (1 constraint(s))
(zcosystem)jjs-macbook-pro:athletesunited JJZ$ python manage.py
makemigrations communities
*Migrations for 'communities':*
*0001_initial.py*:
- Create model City
- Create model Community
- Create model CommunityPost
- Create model Country
- Add field country to communitypost
- Add field user to communitypost
(zcosystem)jjs-macbook-pro:athletesunited JJZ$ python manage.py
makemigrations main
*Migrations for 'main':*
*0001_initial.py*:
- Create model TeamMember
(zcosystem)jjs-macbook-pro:athletesunited JJZ$ python manage.py
makemigrations athletes
*Migrations for 'athletes':*
*0001_initial.py*:
- Create model Athlete
- Create model RegistrationProfile
Up until this point I had no concerns, things seemed to be working as
expected, but what happened next stunned me. The migrate command hung it
just sat there seemingly doing nothing. I hit command c to cancel because
I'm on a mac thinking maybe I had done something wrong and it wouldn't
happen again but it continues.
I tried to run runserver next:
(zcosystem)jjs-macbook-pro:athletesunited JJZ$ python manage.py runserver
Performing system checks...
System check identified no issues (0 silenced).
^C(zcosystem)jjs-macbook-pro:athletesunited JJZ$ python manage.py migrate
^C
As you can see it hung and I had to cancel and hit command c on both
runserver and the following migrate.
Sorry for the wall of text but I just want to put this all out there in
case it gives any awareness. Anyways, here is my speculation to what is
causing the "endless loop" within my models, I say this because I didn't
have this issue up until I started messing with this part of my models.
Here is one of those models (because it has the user FK):
# College Event
class CollegeEvent(models.Model):
collegeid = models.CharField(max_length=30)
user = models.ForeignKey('athletes.Athlete', verbose_name=_('user'),
blank=True, null=True, related_name="%(class)s_events")
creatorname = models.CharField(max_length=30)
creatorurl = models.CharField(max_length=30)
ispublished = models.BooleanField(default=False)
name = models.CharField(max_length=30)
description = models.TextField()
startdate = models.CharField(max_length=30)
enddate = models.CharField(max_length=30)
attendees = models.ManyToManyField(settings.AUTH_USER_MODEL, null=True,
blank=True)
objects = models.Manager()
ceobjects = CollegeEventManager()
def __unicode__(self):
return self.name
def get_creator_full_name(self):
return self.user.first_name + " " + self.user.last_name
The key line being:
user = models.ForeignKey('athletes.Athlete', verbose_name=_('user'),
blank=True, null=True, related_name="%(class)s_events")
I thought maybe it couldn't migrate this because of the FK to Athlete, even
though I used this declaration before my understanding is it includes that
model in the FK. I tried importing the the athlete model from the database
above this definition but there was still no output or change in the issue.
What I'm saying is before this line is the way it is above I had a
foreignkey to settings.AUTH_USER_MODEL. But the funny thing is I actually
had that definition commented out in my settings.py. The reason being I
thought I needed to go that route originally with my Athlete django users
but then realized I would just use a one to one field to a django user.
Thus why I changed it to 'athletes.Athlete'.
# Athlete User
class Athlete(models.Model):
athleteuser = models.OneToOneField(User)
athleteavatar = models.ImageField("Profile Pic", upload_to="images/",
blank=True, null=True, default='images/None/no-img.jpeg')
athletebirthday = models.DateField()
athleteurl = models.CharField(max_length=30, unique=True) #
Must limit to a-z && A-Z && and 0-9 chars, validators=[validate_slug]
athletecommunities = models.ManyToManyField('communities.Community')
athletecolleges = models.ManyToManyField('colleges.College')
I wish I could give more information but I simply can't think of anything
else right now that could be relevant. It's funny because I saw this:
- Modified migrations dependency algorithm to avoid possible infinite
recursion.
on the new release notes:
https://docs.djangoproject.com/en/1.7/releases/1.7.1/
and it honestly seems to sound exactly like that. It seems like some sort
of infinite recursion or something similar it can't get out of it. It can't
identify the issue it gets thrown through and so it sits there endlessly.
And yes again I am using 1.7.1, I just updated the other day.
Thanks a lot,
JJ Zolper
