Insert the current user when creating an object in Database? [duplicate] - django

Question

I am writing an application which stores "Jobs". They are defined as having a ForeignKey linked to a "User". I don't understand how to pass the ForeignKey into the model when creating it. My Model for Job worked fine without a ForeignKey, but now that I am trying to add users to the system I can't get the form to validate.
models.py:
from django.db import models
from django import forms
from django.contrib.auth.models import User
class Job(models.Model):
user = models.ForeignKey(User)
name = models.CharField(max_length=50, blank=True)
pub_date = models.DateTimeField('date published', auto_now_add=True)
orig_image = models.ImageField('uploaded image', upload_to='origImageDB/', blank=True)
clean_image = models.ImageField('clean image', upload_to='cleanImageDB/', blank=True)
fullsize_image = models.ImageField('fullsize image', upload_to='fullsizeImageDB/')
fullsize_clean_image = models.ImageField('fullsize clean image', upload_to='fullsizeCleanImageDB/')
regions = models.TextField(blank=True)
orig_regions = models.TextField(blank=True)
class JobForm(forms.ModelForm):
class Meta:
model = Job
In views.py I was creating the objects as follows:
if request.method == 'POST':
form = JobForm(request.POST, request.FILES)
if form.is_valid():
#Do something here
I understand that this passes the form data and the uploaded files to the form. However, I don't understand how to pass in a User to be set as the ForeignKey.
Thanks in advance to anyone who can help.

Answer 1

A typical pattern in Django is:
exclude the user field from the model form
save the form with commit=False
set job.user
save to database
In your case:
class JobForm(forms.ModelForm):
class Meta:
model = Job
exclude = ('user',)
if request.method == 'POST':
form = JobForm(request.POST, request.FILES)
job = form.save(commit=False)
job.user = request.user
job.save()
# the next line isn't necessary here, because we don't have any m2m fields
form.save_m2m()
See the Django docs on the model form save() method for more information.

Answer 2

Try:
if request.method == 'POST':
data = request.POST
data['user'] = request.user
form = JobForm(data, request.FILES)
if form.is_valid():
#Do something here
