Django Dumpdata Unable To Serialize Database
Django dumpdata Unable to serialize database: Could not decode to UTF-8 column. February 20, 2017, at 3:33 PM. I have a sqlite db which I want to dump. I use the command $ python manage.py dumpdata dump.json. Dec 04, 2013 Not really, managed=False only means Django won't create / modify the table. By having this model in your code Django still expects there to be a table and that table is not there. By having this model in your code Django still expects there to be a table and that table is not there.
$ python manage.py dumpdata CommandError: Unable to serialize database: relation 'corsheaderscorsmodel' does not exist LINE 1.smodel'.' Id', 'corsheaderscorsmodel'.' Cors' FROM 'corsheade. Manually running makemigrations also doesn’t help, because there is no migrations module exists under corsheaders. I know from the sources that it is optional (and undocumented!) to use a model for whitelisting, but bricking management commands is not a Good Way To Go™ Adding corsheaders/migrations/init.py solves the problem, though.
Hi All, I'm trying to dump the contents of a table which is the mapping for a many-to-many field. The table is called Part and it has a ManytoManyField called categoryid. When I run python manage.py dumpdata store.partcategoryid file.json I get the error Error: Unable to serialize database: Category matching query does not exist.
I have validated that all values in the table are valid. The table is defined as follows - id: integer PRIMARY KEY unipartid: integer categoryid: integer Also, when I run dumpdata on the table (python manage.py dumpdata store.part file.json), the data is dumped without an error message but the categoryid field is consistently empty in the output. Any thoughts on what I'm doing wrong?

Natasha Baker Hm, I think the functionality to do this - at least if I understand correctly what I read here: I'd be fine dumping the data for the entire app - but the reason I did it this way is because when I do this, the categoryid field is empty for all parts in the Part table. If I look at the database contents, it should not be blank - so not sure why that's happening. So that's why I wanted to delve deeper.

If I look at the database contents, it should not be blank - so not sure why that's happening. So that's why I wanted to delve deeper. So maybe my actual question should be why is the categoryid many-to-many field showing up blank consistently when I do a dumpdata??

Thanks, Natasha - You received this message because you are subscribed to the GoogleGroups 'Django users' group. Melvyn Sopacua No it doesn't.
It can take a app.model name as well and is more commonly used, since the primary use case for dumpdata is to provide seeds for semi-static data, like a categories table. This misses a unique index on (unipartid, categoryid) but doesn't explain the issues you're seeing. Any chance we can see the actual models and one broken record as outputted by dumpdata? - Melvyn Sopacua - You received this message because you are subscribed to the Google Groups 'Django users' group.
