Re: Integrity Error: column username is not unique

If the user is marked as deleted and we want to do soft delete.What can we do to have the username available again for use. Can we just mask the deleted usernames with some random string so that the actual username can be used? On Sunday, June 24, 2012 10:36:02 AM UTC-4, Dhivya wrote: > > Hi,

Re: Integrity Error: column username is not unique

Hi, username field in django.contrib.auth.User model is unique. Probably, the username you are trying to save already exists. In your view, you might want to check, try: username = User.objects.get(username=form.cleaned_data['username']) except ObjectDoesNotExist: #create user new

Re: Integrity Error

While we're at it, here are a few suggestions. So long as you can, you should use unicode inside python code. The main logic would be that input should be converted to unicode as soon as possible, and that output should be encoded (likely to UTF-8) as late as possible. Consequently, you might

Re: Integrity Error

Actually, the line "invoice = models.ForeignKey(Invoice)" tells Django "An invoice item should always be attached to an invoince". You must realize that models are what they claim to be... models. They are not items of their own, they just define how you would model a particular item in your

Re: Integrity Error

Thanks Thomas your are right concerning the sum there is no need for that. But you say: Your invoice items have no invoice attribute, as the error says. Isn't this line which defines the attribute ? invoice = models.ForeignKey(Invoice) Thanks Torsten On 26 Aug., 11:41, Thomas Orozco

Re: Integrity Error

Your invoice items have no invoice attribute, as the error says. By the way, although I'm not sure of what you're trying to achieve, let me point out that there is not really a need for a sum field in your invoice as you can just sum all the invoice items' amount (and respect the DRY principle -

Re: Integrity Error with generic relation using ContentType

Well, there are some ways around it if you use dumpdata/loaddata statements. But for initial fixtures, it causes trouble. When the DB is created, django will dynamically try to populate the content-types table. But if you are already putting data into that table, the primary keys will clash. When

Re: Integrity Error with generic relation using ContentType

Are you using your own fixtures (like initial_data.json)? Is it possible that in your initial_data.json ( or whatever fixture you're using) that you're including entries into the content_types table? You should probably remove that from your fixtures and let django build the content types

Re: Integrity Error on chained FKs

Daniel, thanks for pointing that out, the amended code now does what it was supposed to do. makes perfect sense when you explained it. i already had the slug and user excluded, which is why it allowed me to add them but didn't validate them im guessing. chained fk's was down to the error

been playing with this some more and i still can't work out what ive done to cause this issue. as i see it, when saving a Venue, the Survey model which is FK'd to the Venue is complaining that the user_id isn't set. However there is nothing being saved by the Survey model, so why is it even

Re: Integrity Error on chained FKs

The error you are getting has something to do with your user field in the Venue model, which based from your models cannot be null. How are you associating a user to it? On Mar 25, 7:45 pm, shofty wrote: > I've got the following models. > > class UserProfile(models.Model): >

Re: Integrity error handling

In your form sub-class class you'll need to override the clean method to check for duplicate entries and raise a validation error if they exists: from somewhere import models from somewhere import forms class myForm(forms.ModelForm): some_unique_field = forms.CharField() class

I've looked into this further, and it looks like it's actually an issue with PostgreSQL, not django. The field I'm querying is of type inet, and I'm inputting an IPv6 address. However, it appears that in PostgreSQL (running version 8.3.5) IPv6 addresses only match a query when the string being

Re: Integrity Error, regarding NULL values

Hey Tim, Yeah, I understand what you mean, but I thought that django used "" by default and not NULL. That's why I defined in my model to allow blank, and not include null=True. Part of the model is this: class Factor(meta.Model): 20 first_name = meta.CharField(maxlength=25)
