I'm creating a clone of fiverr.com as a project.
There's a header in my base.html with category titles that if I click, should filter out only the gigs in the relevant category for display.
What happens is that it always redirects to home regardless. I have done some testing and believe it should be because of the KeyError, and no link is passed to the function correctly.
Code below:
views.py
def category(request, link):
categories = {
"Graphics & Design": "GD",
"Digital & Marketing": "DM",
"Video & Animation": "VA",
"Music & Audio": "MA",
"Programming & Tech": "PT"
}
try:
gigs = Gig.objects.filter(category=categories[link])
return render(request, 'home.html', {"gigs": gigs})
except KeyError:
return redirect('home')
models.py
class Gig(models.Model):
CATEGORY_CHOICES = (
("GD", "Graphics & Design"),
("DM", "Digital & Marketing"),
("VA", "Video & Animation"),
("MA", "Music & Audio"),
("PT", "Programming & Tech")
)
title = models.CharField(max_length=500)
category = models.CharField(max_length = 2, choices=CATEGORY_CHOICES)
description = models.CharField(max_length=1000)
price = models.IntegerField(default=6)
photo = models.FileField(upload_to='gigs')
status = models.BooleanField(default=True)
user = models.ForeignKey(User)
create_time = models.DateTimeField(default=timezone.now)
def get_absolute_url(self):
return reverse('my_gigs')
def __str__(self):
return self.title
base.html (where the links are - tried another way of getting the same link for Graphics & Design, but results were similar)
<nav class="navbar navbar-light bg-faded">
<div class="container">
<ul class="nav navbar-nav">
<li class="nav-item active">
<a class="nav-link" href='category/graphics-design'>Graphics & Design <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="{% url 'category' 'digital-marketing' %}">Digital Marketing</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{% url 'category' 'video-animation' %}">Video & Animation</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{% url 'category' 'music-audio' %}">Music & Audio</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{% url 'category' 'programming-tech' %}">Programming & Tech</a>
</li>
</ul>
</div>
</nav>
urls.py
url(r'^category/(?P<link>[\w|-]+)/$', views.category, name='category'),
Answer
The view is receiving a slug value in link parameter. So, you should redefine the categories dictionary:
def category(request, link):
categories = {
"graphics-design": "GD",
"digital-marketing": "DM",
"video-animation": "VA",
"music-audio": "MA",
"programming-tech": "PT"
}
...
