How to save data from form FileField to DB Django - django

Question

I have a model and have added a Form FileField to take a file and save all their contents for a particular object. The content from the file should be read, parsed, and stored to synonym_name of the model.
model.py
molecule = models.ForeignKey('MoleculeDictionary', blank=False, null=False)
synonym_type = models.ForeignKey('SynonymType')
synonym_name = models.CharField(max_length=50, blank=True)
def __unicode__(self):
return u'%s' % (self.synonym_name)
And this is how I add Form field to the models(admin)page.
form.py
from django.forms import ModelForm
from django.forms import *
import pdb
import os
from django.core.files.uploadedfile import SimpleUploadedFile
from django.core.files import File
from idg.models.molecule_synonym import MoleculeSynonym
class MoleculeSynonymForm(ModelForm):
file_upload = FileField(required=False)
print "YES"
def save(self, commit=True):
print 'saving...'
file_upload = self.cleaned_data.get('file_upload', None)
file_upload.seek(0)
with open("../../Downloads/model_file_upload.txt", 'r') as f:
model_file = File(f)
names = model_file.read()
print(names)
form = MoleculeSynonymForm(names)
return super(MoleculeSynonymForm, self).save(commit=commit)
#
class Meta:
model = MoleculeSynonym
I have two questions:
How should I save the names to the Synonym_name for a chosen synonym_type and molecule. I use sqlite. My current code doesn't throw any errors other than:
The molecule synonym "" was added successfully.
How do I get the "full path for the file" without hardcoding them in the open statement.
Update: tried this :
I know this could be downright stupid :
try:
synonym_name = MoleculeSynonym.objects.create(synonym_name=names)
except:
synonym_name = None
print synonym_name
synform = MoleculeSynonymForm(instance=synonym_name)
print statement prints None.

I dont get what you are trying to this but if this helps have a look:
class MoleculeSynonymForm(ModelForm):
file_upload = FileField(required=False)
class Meta:
model = MoleculeSynonym
def clean_file_upload(self):
file_upload = self.cleanded_data['file_upload']
if file_upload:
model = YourModel()
model.file = file_upload
model.save()
else:
raise errors
Replace YourModel with your model and file with your model file field.
