Re: Problems with dumpdata/loaddata

Hi.

Maybe it would be useful to create ticket to document this behavior in
Django documentation.

Re: Problems with dumpdata/loaddata

[Matthijs Kooijman]

Hey folks,

I'm replying to an old thread about a problem with "manage.py loaddata" 
generating a BOM (byte-order-mark) that "manage.py dumpdata" refuses to 
load. I just ran into this same problem and found that, in my case, the 
problem is not "loaddata", but powershell which I was running under. 
Apparently powershell adds a BOM when redirecting output. For example, a 
simple "echo foo > somefile" also adds a BOM. Seeing the original poster 
was also using Windows, perhaps he was also using powershell (the regular 
Windows cmd.exe does not seem to have this behaviour).

For me, the solution was to just use a different shell, or use the 
"--output" option to dumpdata.

[jorrit787]

I jus tested it again and it happens even without opening the file in an 
editor first. Would that be a bug then?

Re: Problems with dumpdata/loaddata

[Ramiro Morales]

It shouldn't. Are you sure you haven't opened and saved the json file with
a text editor that might be adding the BOM, e.g. Notepad before running
loaddata?

Re: Problems with dumpdata/loaddata

[jorrit787]

Opening the JSON file in Notepad++ certainly gives some insight... It says 
it's encoded in USC-2 LE BOM. Converting it to UTF-8 with BOM in Notepad++ 
solves the problem.

Question though, why does dumpdata create files with an encoding that can 
not be used out of the box with loaddata?

Re: Problems with dumpdata/loaddata

[ludovic coues]

I believe the json file start with 0xff 0xfe, which mark the file as
UTF-16. The problem is that these two character are invalid at the
beginning of a json file.
The problem have the same root for the xml. UTF-16 file but it pretend
it is utf-8 encoded.

These problems might go away on another OS or with python 3.
Another solution might be to open the file with notepad++ and save as
utf-8, without BOM.

Re: Problems with dumpdata/loaddata

[jorrit787]

Thank you for the replies. *members* and *posts* are the names of my apps.

The first line of the XML file when I open it in Notepad says:



The JSON file has no distinguishable first line, it just starts right away 
with the data.

Your apps are called members and posts, or those are the names of the

Re: Problems with dumpdata/loaddata

[ludovic coues]

Both error look like encoding error.
In the JS file, it look like there is a byte order mark at the start
of the file.
The first line of both file might help to understand the error.

Problems with dumpdata/loaddata

[jorrit787]

I want to dump and load data for two apps that I have. Using dumpdata works 
fine:

python manage.py dumpdata members posts > data.json

or

python manage.py dumpdata members posts --format=xml > data.xml

However, when I try to load the same data back with loaddata I get the 
following errors:

What gives?

The example you quote isn't particularly abstract - it's telling you
exactly what to type. You need to type "python ./manage.py loaddata
blah", where blah is the name of your fixture. The two top hits for
"loaddata" on the Django documentation search:

http://docs.djangoproject.com/en/dev/ref/django-admin/?from=olddocs#loaddata-fixture-fixture
http://docs.djangoproject.com/en/dev/howto/initial-data/

both tell you exactly how fixture names are determined.

We might be able to provide a little more help if you are a little
more clear about what you have done, and what errors (if any) you are
seeing. You say you have successfully used dumpdata - what did you
type, what output did you see, and what did you do with that output?

Yours,
Russ Magee %-)

Problems with dumpdata/loaddata

[Gary Thomas]

I'm trying to use the admin interface to dump & restore my database,
without much luck.  I can dump the data fine, but I've had no success
loading it back in.

Could someone list the commands to do this?  The actual commands is
what
I'm looking for (not present in the docs) - something that I can type
and see work,
not abstract things like 'python manage.py loaddata '...

Thanks for the help
