I try to follow the ideas, but i feel like taking the dirty way.
Here's my work:
Because i can't replace the modelform created by the admin for the
"Data" model with a standard form as the Django docs says, i created a
view to replace the "add" view generated by the admin and put a
standard form:
class DataAdmin(admin.ModelAdmin):
change_form_template = 'admin/data/data/change_form.html'
def get_urls(self):
urls = super(DataAdmin, self).get_urls()
my_urls = patterns('',
('^add/$',
self.admin_site.admin_view(self.add_view)),
)
return my_urls + urls
def add_view(self, request, extra_content=None):
FormInput = DataInput()
context = {'form': FormInput}
return super(DataAdmin, self).add_view(request,
extra_context=context)
And the form is:
import csv
from datetime import datetime
class DataInput(forms.Form):
file = forms.FileField()
place = forms.ModelChoiceField(queryset=Places.objects.all())
def save(self):
records = csv.reader(self.cleaned_data["file"])
for line in records:
input_data = Data()
input_data.place = self.cleaned_data["place"]
input_data.time = datetime.strptime(line[1], "%m/%d/%y %H:
%M:%S")
input_data.data_1 = line[2]
input_data.data_2 = line[3]
input_data.data_3 = line[4]
input_data.save()
In the template are the "multipart/data" and "csrftoken" orders.
But again... this is a karma.... the IntegrityError: datas_data.time
may not be NULL
As i say at the beginning, i feel like taking the dirty way, and
obviously not seeing something.
Regards!
