Good to hear. I've opened ticket #4459 to address the problem; I've got some ideas on how to fix the issue, but I need to have a closer look.

I have seen this error before. That time, it wasn't (technically) due to a fault in the serializer - it was caused by a model overriding the save() method. In the overridden save() method, there a query was performed on the database, but the required objects had not yet been loaded. Are you overriding save() in any of your models (in particular, anything querying StaticPage model? The only workaround I know of for this is to do your dump in stages, so that the data required by the query in the save() method is available at the time the saved object. However, this approach isn't always possible (depending on the circular relationships in your data).

Migrate data between computers
Hello, I would like migrate data from my Django project on notebook (computer1) to another machine (computer2). To perform this, I follow this steps: 1) On computer1 I call ./manage.py dumpdata > all.json 2) On computer2 I setup exactly same version of my Django project. Next I call ./manage.py syncdb which create all necessary DB tables and (unfortunately for me) all fixtures+initial data (like auth_permission, django_site, admin user, etc). 3) Because all.json file contains all data from computer1, I call ./manage.py sqlflush on computer2. This give me SQL statements, which I used to "clear" all data from fresh database on computer2. 4) Now I could call ./manage.py loaddata ./all.json Is this approach correct? I ask you for this, because I have problem to load data on computer2. My effort ends with error message: [EMAIL PROTECTED] app $./manage.py loaddata all.json Loading 'all' fixtures... Installing json fixture 'all' from absolute path. Problem installing fixture 'all.json': StaticPage matching query does not exist. I don't know what I should do now. Even, if I set --verbosity 2 to ./manage.py I don't get any usefull information what is wrong. Is it possible to found somehow where is the problem? Note: I used unicode branch [5387] on both computers, but I supposse, that this is some general problem Regards Michal --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
