Implementing views with template in django - django

Question

I'm struggling to show on a webpage some model objects I created from the admin pages on my site.
I combed through the relevant django tutorial page but nothing I've tried works to show the model objects on the page.
Here is my models.py:
from django.db import models
from datetime import datetime
from datetime import timedelta
# Create your models here.
def get_deadline():
return datetime.today() + timedelta(days=3)
class JobPost(models.Model):
created_at = models.DateTimeField(auto_now_add=True, blank=True)
deadline = models.DateField(default=get_deadline)
wordcount = models.IntegerField()
jobtaken = models.BooleanField(default=False)
# client = models.User.username
class Meta:
ordering = (
# ("jobtaken"),
("-created_at"),
)
def publish(self):
self.pub_date = timezone.now()
self.save()
def __str__(self):
return "Job #{}".format(self.pk)`
views.py:
from django.shortcuts import render
from django.views.generic import TemplateView
#from django.contrib.auth.decorators import staff_member_required
from .models import JobPost
from django.utils import timezone
# Create your views here.
# #staff_member_required()
# class JobBoardView(TemplateView):
# template_name = "jobs.html"
# posts = JobPost.objects.filter(published_date__lte=timezone.now()).order_by('pub_date')
#changed published_date to pub_date in .models
def jobs(request):
#posts = JobPost.objects.filter(published_date__lte=timezone.now()).order_by('published_date')
latest_post_list = JobPost.objects.order_by('-pub_date')
context = {
'deadline': deadline,
'created_at': created_at,
'wordcount':wordcount,
'jobtaken':jobtaken,
'JobPost':JobPost,
'latest_post_list':latest_post_list,
}
return render(request, 'jobs.html', context=context)
urls.py:
from django.contrib import admin
from django.urls import path, re_path, include
from django.conf.urls import url
from django.contrib.auth import views as auth_views
from jobboard import views
from login import views
urlpatterns = [
path('admin/', admin.site.urls),
#re_path(r'^login/$', auth_views.login(template_name = 'accounts/login.html'), name='login'),
re_path(r'^signup/$', views.signup, name='signup'),
path('login/', include('login.urls')),
path('', views.index, name='index'),
path('accounts/', include('django.contrib.auth.urls')),
path('users/', include('users.urls')),
path('users/', include('django.contrib.auth.urls')),
path('jobs/', views.jobs, name='jobs')
]
Here is my template(jobs.html):
{% extends "base.html" %}
{% block content %}
{% if latest_post_list %}
<ul>
{% for post in latest_post_list %}
<li>{{ JobPost }}</li>
{% endfor %}
</ul>
{% else %}
<p>No posts are available.</p>
{% endif %}
{% endblock content %}
I tried various templates, including some really simple ones to test, e.g.
{% if latest_post_list %}
<p>hello</p>
{% else %}
<p>No posts are available.</p>
{% endif %}
but everything I try returns the 'else' part of the if statement. Nothing will show the objects on the webpage.

Answer 1

You have a made a few mistakes which I will list below:
Your query method is wrong. It should be:
latest_post_list = JobPost.objects.all().order_by('-pub_date')
or
latest_post_list = JobPost.objects.filter(something=something).order_by('-pub_date')
2. latest_post_list is not an object, it is a query of JobPost objects. If you wish to iterate them in the template, you can just pass it to the template and do the iteration from the query. However,
context = {
'deadline': deadline, # you cannot access deadline (which deadline?)
'created_at': created_at, # same as above
'wordcount':wordcount, # same as above
'jobtaken':jobtaken, # same as above
'JobPost':JobPost, # You are sending the class to the template which is wrong
'latest_post_list':latest_post_list, # the only thing you need!
}
If you wish to loop through the objects of the query in the back-end, you have to do the following:
for post in latest_post_list:
print(post.deadline) # will print the deadline of each JobPost one by one
If you wish to loop through the objects of the query and display them in the template, you have to do this:
{% for post in latest_post_list %}
<p>{{ post.deadline }} - {{ post.created_at }}</p>
{% empty %}
<p>There is no post yet!</p>
{% endfor %}
There is no need to user if in the backend or use {{ JobPost }}. if the query is empty, the {% empty %} will be effective.

RoboBear was correct, it was a name collision in the urls.py file. This fixed the error:
change to from jobboard import views as job_views and change the url line to path('jobs/', job_views.jobs, name='jobs').
Changing this raised exceptions in the views.py file for all the context dictionary entries except for
context = {
'latest_post_list':latest_post_list,
}
as Ramtin suggested.
Then I changed the template to
<ul>
{% for post in latest_post_list %}
<li>{{ post }}</li>
</ul>
{% empty %}
<p>No posts are available.</p>
{% endfor %}
as Ramtin suggested.
