Hi,
I'm having some trouble setting up a fixture for a model (Dataset)
that has a many-to-one relation with another model, DataSource. My
initial try at this was to put "datasource_id": "1" (the "1" points to
a datasource fixture in another file) in the dataset fixture, but that
results in
"Problem installing fixture '/dev/myproject/myapp/fixtures/
datasets.json': Dataset has no field named u'datasource_id'". I
initially thought that the datasource_id field in the db wasn't being
created, but a look at the generated sql as well as a peek at the
database itself shows this not to be the case. The error instead seems
to refer to the model itself, which has the declaration:
"datasource = models.ForeignKey(DataSource)"
I tried changing the fixture line to "datasource": "1", but this
results in the stack trace below. Does anyone know how to set up this
fixture properly?
Thanks,
James
