Django Wang novice's question! I can't print it out from the long-range db.

# index.html
<tbody>
       {% {% for post in job_opening %}
        <tr>
             <td>{{ post.title }}</td>
             <td>{{ post.target }}</td>
             <td>{{ post.department }}</td>
             <td>{{ post.period }}</td>
             <td> Button</td>
         </tr>
        {% {% endfor %}
</tbody>

# view.py
def index(request):
    template = loader.get_template('mainapp/index.html')
    post = job_opening.objects.all()
    context = {'post' : post}
    return render(request, 'mainapp/index.html', context)

# models.py
class job_opening(models.Model):
    title = models.CharField(max_length=200,verbose_name='title')
    target = models.CharField(max_length=50)
    department = models.CharField(max_length=10)
    period = models.CharField(max_length=50)
    content = models.TextField()

    def __str__(self):
        return self.title
