import error, 'get() keywords must be strings'

I’m having trouble getting a form to accept data on import. Currently testing csv format file; get same errors with xls file.

sample from import.csv:

jid,project_code,collab_id,sample_code,sequencing_type
JMQN3H,AAST,42567,ST,1
JO2FT1,AAST,43267,ST,1

The error coming out is get() keywords must be strings.

django error log:

Line number: 1 - get() keywords must be strings
OrderedDict([('jid', 'JMQN3H'), ('project_code', 'AAST'), ('collab_id', '42567'), ('sample_code', 'ST'), ('sequencing_type', '1')])
Traceback (most recent call last):
File "/var/www/django/jid_generator/lib/python3.4/site-packages/import_export/resources.py", line 356, in import_data
instance, new = self.get_or_init_instance(instance_loader, row)
File "/var/www/django/jid_generator/lib/python3.4/site-packages/import_export/resources.py", line 186, in get_or_init_instance
instance = self.get_instance(instance_loader, row)
TypeError: get() keywords must be strings

I tried putting the values in csv file inside quotes. I tried modifying the admin, form and the Resource widgets.

admin.py:

"""ImportExport Resource"""
class DetailResource(resources.ModelResource):
    jid = fields.Field(
        default=generate_Jid(prefix='J'),
        readonly=True,
        widget=widgets.CharWidget(),
        )
    project_code = fields.Field(column_name='project_code', attribute='project_code',
        widget=widgets.ForeignKeyWidget(ProjectCode, 'code'),
        )
    sample_type = fields.Field(
        widget=widgets.ForeignKeyWidget(SampleType, 'code'),
        )
    sequencing_type = fields.Field(
        widget=widgets.ForeignKeyWidget(SequencingType, 'code'),
        )
    collab_id = fields.Field(
        widget=widgets.CharWidget(),
        )

    class Meta:
        model = JIdDetail
        all_fields = ( 'jid', 'project_code', 'collab_id',
                'sample_type', 'sequencing_type', )
        import_id_fields = ( 'jid', )
        fields = all_fields
        export_order = all_fields

@admin.register(JIdDetail)
# class JIdDetailAdmin(admin.ModelAdmin):
class JIdDetailAdmin(ImportExportModelAdmin):
    resource_class = DetailResource

    # has_add_permission removes the individual 'add' admin action
    # def has_add_permission(self, request):
        # return False

    form = JIdDetailForm
    actions_on_top = False
    actions = None
    all_fields = ( 'jid', 'project_code', 'collab_id',
            'sample_type', 'sequencing_type', )
    fields = ( all_fields, )
    list_display = all_fields
    search_fields = all_fields
    readonly_fields = ( 'jid' ),
    list_filter = ( 'sample_type', 'sequencing_type', 'project_code' )
    ordering = ['creation_date', 'project_code', 'sequencing_type']

forms.py:

class JIdDetailForm(forms.ModelForm):
    class Meta:
        model = JIdDetail
        fields = ( 'jid', 'project_code', 'collab_id',
                'sample_type', 'sequencing_type', )
        readonly_fields = ( 'jid' ),

        # widgets = {
            # 'jid': forms.TextInput(attrs={'size':'6'}),
            # 'collab_id': forms.TextInput(attrs={'size':'40'}),
            # }

models.py

class JIdDetail(models.Model):
    verbose_name = 'J Id Detail'
    jid = models.CharField('J ID',
            max_length=6, blank=False,
            help_text="A unique ID string for every sample.",
            unique=True,
            )
    project_code = models.ForeignKey(ProjectCode, to_field='code')
    collab_id = models.TextField('Collaborator ID', blank=False,
            help_text="Collaborator sample ID."
            )
    sample_type = models.ForeignKey(SampleType, to_field='code')
    sequencing_type = models.ForeignKey(SequencingType, to_field='code')
    creation_date = models.DateTimeField(auto_now_add=True)

Any tips on how to troubleshoot this?

Thanks! -Benjamin-

Works very well! Thanks for your assistance! It’s all in the attribute’s. Need to search docs for them and figure out what they’re used for now. 😃
