Re: How to load data to auth_permissions from initial_data.json when the auth_groups is also loaded from fixture?

[Jason]

I'm investigating this as well. I just read that using the natural
keys dumpdata option might help.

How to load data to auth_permissions from initial_data.json when the auth_groups is also loaded from fixture?

[ycseattle]

Hi, 

In my application, I have fixed groups (like admin, staff, subscribers) 
etc, and this data in auth_groups is not intended to change in the program, 
so I am loading them in initial_data.json. I also want to load data into 
auth_group_permissions as the application is not expected to change it. The 
problem is that I noticed the table auth_permissions is generated by 
Django, so the permissions IDs will be dynamic (especially when I add new 
models as it seems the permissions are ordered by the model names). Is 
there a way to load my definition of group permissions through 
initial_data.json, or am I stuck with running a piece of code to do this? 

Thanks,
Yi

The OP clearly doesn't understand why though, see his other thread on
this topic.

Your browser is a careful beast. It won't allow a webpage loaded from
the internet zone to load things from the local zone, as That Would Be
Bad. When you 'double click' the file and 'it works', what is actually
happening is that the webpage is loaded from the local zone, and so
access is allowed.

Also, Django is a web app. This means that most users who use your
site will not be using it from your desktop, so they would not be able
to access files on your local machine. Therefore, you need to provide
a way to serve these files over HTTP, so that other users can access
them. See the link in Daniel's reply on how to do this.

Cheers

Tom

No, you can't do that. Why would you want to? Your users aren't going to 
have that file on their machines, so what's the point of referencing a local 
file path?

You serve the content through your webserver, with an http:// protocol. In 
development, you can do this through Django's development server:

Re: how to load data?

[Reiner]

Fields seperated with \t sounds a bit like a CSV export right? I
needed to import CSV too, so I used the csv module to parse the file
and then django models to store it in the database, no custom sql
needed.

# set up django environment
[ ... ]
import csv
reader = csv.reader(open('file.csv', 'r'), delimiter=r'\t',
quotechar='"')
for row in reader:
   myapp.mymodel.objects.create(
  pk=row[0],
  title=row[1],
  ...
   )

If it's an actual db dumb (aka SQL) you can just give it strait to the db.
Otherwise you'll probably need to write a script to parse it and create
objects and save them.

What kind of files are these? If they are existing legacy data files, 
you'll have to write some sort of de-serializer to translate them to fit 
your model(s).

If the file happens to be one of the serialization formats that Django 
already knows how to deal with, you might be able to use Django's 
serialization somehow.

But some more specifics on your data format will allow us to help you more.
