Save user who submitted form(django)
Question
So I'm creating a reporting app for my organization I want to be able to save the user that submits the report. Problem is if I use the models.ForeignKey(User,on_delete=models.PROTECT) method on my model I get a drop down for all the users which is not what I want.
models.py
class Report(models.Model):
id = models.UUIDField(primary_key=True,default=uuid.uuid1,editable=False)
department = models.ForeignKey(Company,null=True,on_delete=models.SET_NULL)
user= models.ForeignKey(User,on_delete=models.PROTECT)
submission_date= models.DateField(auto_now=True) #invisible to user
submission_time = models.TimeField(auto_now=True) #invisible to ,user
date = models.DateField(default=now,blank=False)
time = models.TimeField(default=now,blank=False,help_text="hh:mm:ss")
location = PlainLocationField()
building = models.ForeignKey(bld,null=True,on_delete=models.SET_NULL)
size = models.PositiveIntegerField()
notes = models.TextField(blank=True)
def __str__(self):
return f'{self.date} {self.time} ({self.company})
form.py
from django.forms import ModelForm, fields
from django.shortcuts import redirect
from django.urls.conf import include
from .models import Report
from django import forms
from location_field.forms.plain import PlainLocationField
class ReportForm(forms.ModelForm):
class Meta:
model = Report
fields = '__all__'
location = PlainLocationField()
def redirect():
return redirect("Report")
views.py
from django.forms import fields
from django.forms.forms import Form
from django.http import request
from django.http.request import HttpRequest, validate_host
from django.http.response import HttpResponse, HttpResponseRedirect
from django.shortcuts import render,redirect
from django.urls.base import reverse
from django.views.generic.base import TemplateView
from django.contrib.auth import authenticate, login
from django.contrib.auth.mixins import LoginRequiredMixin
# Create your views here.
from .forms import ReportForm
from .models import Report
from django.views.generic.edit import CreateView, UpdateView, DeleteView
class ReportCreate(LoginRequiredMixin,CreateView):
Template = "templates\reports\report.html"
model = Report
fields = '__all__'
def form_valid(self, form):
return super().form_valid(form)
def get_success_url(self):
return reverse('Report')
def home(request):
return render(request,"users/home.html")
EDIT: templates/report_form.html
{% extends "base_generic.html" %}
<head>
</head>
<body>
{% block content %}
<form action="" method="post" onsubmit="return True">
{% csrf_token %}
<table>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<input type="hidden" name="user" value= "{{ request.user }}">
{{ form.as_table }}
{{ form.media }}
</table>
<input type="submit" value="Submit">
</form>
{% endblock %}
</body>

There's a few of ways to go about this.
You can add blank=True to user model field and assign the user when overriding the form_valid method:
def form_valid(self, form):
form.instance.user = self.request.user
form.instance.save()
return super(ReportCreate, self).form_valid(form)
Or, render the user form field as a hidden field and pre-populate it:
<input type="hidden" name="user" value="{{ request.user }}

try to use model.CASCADE instead of model.PROTECT .
