Django，外键没有被会话数据填充

Question

我试图用登录的用户填写我的外键(雇主)，但我看到了很多方法，但他们没有为我工作，有人知道我做错了吗?我该怎么补救呢?

视图:

class JobCreate(CreateView):
model = Job
form = JobCreateForm()
form_class = JobCreateForm
context = {}
success_url = reverse_lazy('jobsview')
def POST(self,request):
if request.method == 'POST':
form = JobCreateForm(request.POST)
if form.is_valid():
job = form.save(commit=False)
job.employer = request.user
job.save()
context = {}
return render(request, 'jobs/jobs.html',context)
else:
context = {}
return render(request, 'jobs/job_form.html',context)

模型:

class Job(models.Model):
employer = models.ForeignKey(User, related_name='employer', on_delete=CASCADE,blank=True)
employees = models.ManyToManyField(User, related_name='employees2user',null=True,blank=True)
title = models.CharField(max_length=200,)
description = models.CharField(max_length=200,null=True,blank=True)
category_id = models.ManyToManyField(Category,blank=True)
skill_id = models.ManyToManyField(Skill,blank=True)
approved = models.BooleanField(default=False)
# img = models.ImageField(null=True, blank=True)
created_at = models.DateTimeField(auto_now_add=True)

def __str__(self):          # Default value
return self.title

HTML:

{% extends "jobs/layout.html" %}
{% block content %}
<h3> Job</h3>
<div class="container">
<div class="jobform">
<form action="" method="POST">
{%csrf_token%}
{% for field in form %}
<label for="{{field.id_for_label}}">{{field.html_name}}</label>
{{field}}
{% endfor %}
<p>Ctrl in houden om meerder te selecteren</p>
<button type="submit" class="btn btn-dark btn-space">Submit</button>
</form>
</div>
</div>
{%endblock%}

在views方法中，尝试替换

job = form.save(commit=False)
job.employer = request.user
job.save()

self.object = form.save(commit=False)
self.object.employer = self.request.user
self.object.save()

还有，context{}的目的是什么?

你能直接把它放在form_valid方法里面吗?这样干净多了。

def form_valid(self, form):
self.object = form.save(commit=False)
self.object.employer = self.request.user
self.object.save()
return super(JobCreate, self).form_valid(form)
