I'm beginner on Django.
I have a project with the following models:
My Articles models:
class Post(models.Model):
title = models.CharField(max_length=200)
slug = models.SlugField(max_length=160)
content = models.TextField()
image = models.ImageField(upload_to=upload_location)
timestamp = models.DateTimeField(auto_now=False, auto_now_add=True)
updated = models.DateTimeField(auto_now=True, auto_now_add=False)
categorie = models.CharField(max_length=200)
categorie = models.ForeignKey('categorie.Categorie')
publier = models.BooleanField()
My Portfolio categories models which is linked with my Article Model:
class Categorieport(models.Model):
title = models.CharField(max_length=200)
article = models.OneToOneField('posts.Post')
And finally, my portfolio models with all the photos:
class Portfolio(models.Model):
title = models.CharField(max_length=200)
image = models.ImageField(upload_to=upload_location)
timestamp = models.DateTimeField(auto_now=False, auto_now_add=True)
updated = models.DateTimeField(auto_now=True, auto_now_add=False)
categorieportfolio = models.ForeignKey('Categorieport')
In one view and one template, i'd like to display information concerning the article and the portfolio related to the article.
I wrote the following view:
def portfolio(request, article=None):
portfolio = get_object_or_404(Categorieport, article=article)
image_portfolio = portfolio.portfolio_set.all()
return render(request, 'portfolio1.html', {'portfolio': portfolio, 'image_portfolio': image_portfolio})
And the following templates:
<div class="titre-display">
<h2>{{ portfolio.article.timestamp|date:"d E Y" }} / {{ portfolio.article.categorie}} </h2>
<h1>{{ portfolio.article.title}}</h1>
</div>
<div class="content-display">
<div class="content-display-main">
<div class="content-display-main-portfolio">
<div class="image-portfolio">
<a class="example-image-link" href="{{ image_portfolio.image.url }}" data-lightbox="example-set" data-title="{{image_portfolio.title}}">
</a>
I can access to information from my article but i can't access information from my portfolio. I tried it with the shell, and it works. I can't figure out why it doesn't work in my view and template.
Do you have any idea?
Thank you in advance

Try this:
# views.py
def portfolio(request, article=None):
# first get the Post instance with slug = article (I'm assuming article passed as url argument, is a slug)
post = get_object_or_404(Post, slug=article)
# get the Categoriepost object based on a specifi article
categorie_port = get_object_or_404(Categorieport, article=post)
# image_portfolio is a QuerySet (that is a list of Portfolio objects)
image_portfolio = categorie_port.portfolio_set.all()
return render(request, 'portfolio1.html', {'portfolio': categorie_port, 'image_portfolio': image_portfolio})
Leave your HTML as is.
Your image_portfolio is a querySet, that's means is some kind of list, you have to use a loop to access the items and them access the properties:
<div class="content-display">
<div class="content-display-main">
<div class="content-display-main-portfolio">
<div class="image-portfolio">
{% for item_img in image_portfolio %}
<a class="example-image-link" href="{{ item_img.image.url }}" data-lightbox="example-set" data-title="{{item_img.title}}"></a>
{% endfor %}
Hi thank you all for your answer.
So, I used a for loop for solving my case as mentioned previously.
Below, my code:
<div class="titre-display">
<h2>{{ portfolio.article.timestamp|date:"d E Y" }} / {{ portfolio.article.categorie}} </h2>
<h1>{{ portfolio.article.title}}</h1>
</div>
<div class="content-display">
<div class="content-display-main">
<div class="content-display-main-portfolio">
{% for photo in image_portfolio %}
<div class="image-portfolio">
<a class="example-image-link" href="{{ photo.image.url }}" data-lightbox="example-set" data-title="{{photo.title}}">
{% thumbnail photo.image "300x300" crop="center" as im %}
<img class="example-image" src="{{ im.url }}" alt=""/>
{% endthumbnail %}
</a>
<p>{{photo.title}}</p>
</div>
{% empty %}
<p>Aucun portfolio.</p>
{% endfor %}
</div>
</div>
And my views:
def portfolio(request, slug=None, article=None):
slug = get_object_or_404(Post, slug=slug)
portfolio = get_object_or_404(Categorieport, article=article)
image_portfolio = portfolio.portfolio_set.all()
return render(request, 'portfolio.html', {'portfolio': portfolio, 'image_portfolio': image_portfolio})
Thanks again for your help
