ProgrammingError relation "uploader_email" does not exist - django

Created a new model called Email, but using makemigrations and migrate I am getting no changes detected. Upon runserver, I get the following error:
ProgrammingError at /admin/uploader/email/
relation "uploader_email" does not exist
LINE 1: SELECT COUNT(*) AS "__count" FROM "uploader_email"
I have tried every suggestion on stackoverflow, I have:
Deleted migrations files
ran migrate --fake and --fake-initial
migrate uploader (calling the app specifically)
Nothing is working, the DB simply will not be modified.
Any ideas?

You can use from django get_image_dimensions:
from django.core.files.images import get_image_dimensions
class CauroselImageForm(forms.ModelForm):
...
def clean(self):
width, height = get_image_dimensions(self.cleaned_data.get('image'))
if width < 1300 or height < 400:
raise forms.ValidationError("Image dimensions is too small, minimum is 1300x400")
return cleaned_data
Method get_image_dimensions is using python PIL (Python Imaging Library).
get_image_dimensions returns the (width, height) of an image, given
an open file or a path. Set 'close' to True to close the file at the
end if it is initially in an open state.

Django error: invalid literal for int() with base 10: b'01/12/1990'

I have created a Profile and Blog model in my Django application.
Here is the models.py file below:
from django.db import models
# Create your models here.
class Profile(models.Model):
name = models.CharField(max_length=30)
description = models.TextField()
number = models.CharField(max_length=10)
dob = models.DateField()
class Blog(models.Model):
title = models.CharField(max_length=30)
content = models.TextField()
blog_document = models.FileField(upload_to='documents/', null=True, blank=True)
And in my admin panel, for profile model: I want to view two or more columns in the table, something like this:
However this line is giving me the error since I do not know how to present more than one column appear in the Profile table:
def __str__(self):
return '%s %s' % (self.name, self.number)
What would be the correct solution for implementing two or more fields in the Profile table(admin panel).
Update
class ProfileAdmin(admin.ModelAdmin):
list_display = ('name', 'description', 'number', 'dob')
admin.site.register(Profile, ProfileAdmin)
class BlogAdmin(admin.ModelAdmin):
list_display = ('title', 'content')
admin.site.register(Blog, BlogAdmin)

Model thinks my string is tuple and won't save

I have a model that I'm trying to override save on, but when I pass the information it thinks the string is a tuple, and won't save the information in the model. The particular field I'm pulling in is a single line address that looks like this: 3107 Eric Motorway, Lake William, GU 71954, but my model thinks the commas are a tuple. I've tried casting it to a string and everything.

Your __str__ is a tuple. Your version:

You can try something like
def __str__(self):
return "%s %s %s" % (self.po_number, self.pu_customer, self.del_location)
and it should work just fine :)

Your form takes request_client_id as the first argument. Therefore you must pass request_client_id every time the form is submitted, including when you do a post request.
if request.method == 'POST':
form_order = OrderCreateForm(request_client_id, request.POST)
change your form like this:
BLANK_CHOICE = ((0, '---------'),)
class OrderCreateForm(forms.ModelForm):
tag_from = forms.MultipleChoiceField(label='Tags')
tag_to = forms.MultipleChoiceField()

model = Order

django-mptt ValueError: Cannot use None as a query value

Trouble was here:
class MPTTMeta:
order_insertion_by = ['id']
I changed 'order_insertion_by' field to another (to 'created' in my example) and it began to work
I found the cause of this error by using the "node_order_by" attribute when referencing a field using auto_now in a MP_node subclass....
Class Tree(MP_Node):
name = models.CharField(max_length=45)
last_modified = models.DateTimeField(auto_now=True)
node_order_by = ['last_modified']
Commented out node_order_by or using a different field and the error went away. I think the issue is that Treebeard is trying to figure out where to insert the child record and it doesn't have a date yet for the new record.
