Hi I am letting the user upload multiple images per project but so far the images are not displayed. In projects.html all projects should be displayed and the title and the describtion work so far. But the main-image doesn´t show up. In single-project all images should be displayed.
What do I have to change in my models.py?
Thanks in forward
models.py
class Project(models.Model):
title = models.CharField(max_length=200)
describtion = models.TextField(null=True, blank=True)
id = models.UUIDField(default=uuid.uuid4, unique=True, primary_key=True, editable=False)
class ProjectImage(models.Model):
project = models.ForeignKey(Project, on_delete=models.CASCADE)
featured_images = models.FileField()
forms.py
class ProjectForm(ModelForm):
featured_images = forms.ImageField(widget=ClearableFileInput(attrs={'multiple':True}))
class Meta:
model = Project
fields = ['title', 'describtion', 'featured_images']
views.py
def createProject(request):
form = ProjectForm()
if request.method == 'POST':
form = ProjectForm(request.POST)
images = request.FILES.getlist('image')
if form.is_valid():
project = form.save()
for i in images:
ProjectImage(project=project, image=i).save()
context = {'form':form}
return render(request, 'projects/project_form.html', context)
def projects(request):
projects = Project.objects.all()
context = {"projects":projects}
return render(request, 'projects/projects.html', context)
def project(request, pk):
projectObj = Project.objects.get(id=pk)
return render(request, 'projects/single-project.html', {'project':projectObj})
projects.html
{% for project in projects %}
<div class="column">
<div class="card project">
<a href="{% url 'project' project.id %}" class="project">
<img class="project__thumbnail" src="{{project.featured_images.url}}" alt="project thumbnail" />
<div class="card__body">
<h3 class="project__title">{{project.title}}</h3>
<h3 class="project__title">{{project.price}} €</h3>
</div>
</a>
</div>
</div>
{% endfor %}
single-project.html
<h3 class="project__title">{{project.title}}</h3>
<h3 class="project__title">{{project.price}} €</h3>
<h3 class="singleProject__subtitle">Infos zum Produkt</h3>
{{project.describtion}}
project_form.html
<form class="form" method="POST" enctype="multipart/form-data">
{% csrf_token %}
{% for field in form %}
<div class="form__field">
<label for="formInput#text">{{field.label}}</label>
{{field}}
</div>
{% endfor %}
<input class="btn btn--sub btn--lg my-md" type="submit" value="Submit" />
</form>
To access the images of a project, you need to use the related manager in your templates:
projects.html
{% for project in projects %}
<div class="column">
<div class="card project">
<a href="{% url 'project' project.id %}" class="project">
<img class="project__thumbnail" src="{{project.projectimage_set.all.0.featured_images.url}}" alt="project thumbnail" />
<div class="card__body">
<h3 class="project__title">{{project.title}}</h3>
<h3 class="project__title">{{project.price}} €</h3>
</div>
</a>
</div>
</div>
{% endfor %}
I assumed that by "main-image" you mean the first image of the project.
single-project.html
<h3 class="project__title">{{project.title}}</h3>
<h3 class="project__title">{{project.price}} €</h3>
<h3 class="singleProject__subtitle">Infos zum Produkt</h3>
{{project.describtion}}
{% for projectimage in project.projectimage_set.all %}
<img src="{{projectimage.featured_images.url}}"/>
{% endfor %}
To avoid the N+1 query problem, you can also change the query in your view:
views.py
def projects(request):
projects = Project.objects.all().prefetch_related('projectimage_set')
context = {"projects":projects}
return render(request, 'projects/projects.html', context)

I am trying to upload multiple files in Django form. I followed multiple methods. I am successful via models to views but I want via models to forms to views.

There is some problem, I'm trying to update the product on the client by making changes and clicking on the update button - my page is refreshing w/o updating info, so the product has the same data as before. But in the logs, the status code of the GET request is 200 and shows the updated object in the database. When I try to update through the admin Django dashboard, everything works successfully, the problem is only on the client side of the web application. What issues can there be?
Thank you in advance!

You have forgotten to pass POST method you are using GET.

I want to add comments form a specific html which has it's separate views and models and I don't want to create a new form.html just to display the form and its views. But I'm stuck. I can add comments manually from the admin page and it's working fine, but it seems that I have to create another url and html file to display the comment form and for users to be able to add comments(btw I'm trying to build a sports related website). Thanks in advance!

You don't have to.
In your HTML, take out the anchor tag, you only need the submit button.
<form method="POST">
{% csrf_token %}
<div class="bg-alert p-2">
<div class="d-flex flex-row align-items-start">{{ form.body }}</div>
<div class="mt-2 text-right"><button class="btn btn-primary btn-sm shadow-none" type="submit">
Post comment</button><button class="btn btn-outline-primary btn-sm ml-1 shadow-none" type="button">Cancel</button></div>
</div>
In your views.py, do this.
def view_that_loads_the_page(request, news_id):
news = Transfernews.objects.get(id=news_id)
form_class = CommentForm(request.POST or None)
if form_class.is_valid():
# save both news and logged in user
form.instance.transfernews = news
form.instance.user = request.user
# save form.
form_class.save()
# returns to the same page
return HttpResponseRedirect(request.path_info)
return render(request, "your_html.html", {"form" : form_class})
I've been trying to display the exact values of model with ManyToMany relation but I just couldn't, all what I've achevied is receiving QuerySet
<QuerySet [<Stack: PHP>, <Stack: js>]>
by adding to template tags
{{ brand.technologies.all }}
But I would like to receive and display 2 fields, name and icon. I've tried with some loops like
{% for brand in brands %}
{% for technologies in brand.technologies.all %} {{ technologies.name }} {{ technologies.icon }} {% endfor %}
{% endfor %}

I don't understand why you've suddenly added an outer loop through brands. You don't have anything called brands, and you're successfully accessing all the other data via brand. Just continue to do so, and drop the outer loop.
<div class="technologies-wrapper">
{% for technologies in brand.technologies.all %} {{ technologies.name }} {% endfor %}

I try to add follow button in django with Getstream.io app.
Following the getstream tutorial, django twitter, I managed to create a list of users with a functioning follow button as well as active activity feed. But when i try add follow button on user profile page, form send POST but nothing happends later.
I spend lot of time trying resolve this, but i'm still begginer in Django.
Code:
Follow model:
class Follow(models.Model):
user = models.ForeignKey('auth.User', related_name = 'follow', on_delete = models.CASCADE)
target = models.ForeignKey('auth.User', related_name ='followers', on_delete=models.CASCADE)
created_at = models.DateTimeField(auto_now_add = True)
class Meta:
unique_together = ('user', 'target')
def unfollow_feed(sender, instance, **kwargs):
feed_manager.unfollow_user(instance.user_id, instance.target_id)
def follow_feed(sender, instance, **kwargs):
feed_manager.follow_user(instance.user_id, instance.target_id)
signals.post_delete.connect(unfollow_feed, sender=Follow)
signals.post_save.connect(follow_feed, sender=Follow)
Views:
def user(request, username):
user = get_object_or_404(User, username=username)
feeds = feed_manager.get_user_feed(user.id)
activities = feeds.get()['results']
activities = enricher.enrich_activities(activities)
context = {
'user': user,
'form': FollowForm(),
'login_user': request.user,
'activities': activities,
}
return render(request, 'profile/user.html', context)
def follow(request):
form = FollowForm(request.POST)
if form.is_valid():
follow = form.instance
follow.user = request.user
follow.save()
return redirect("/timeline/")
def unfollow(request, target_id):
follow = Follow.objects.filter(user=request.user, target_id=target_id).first()
if follow is not None:
follow.delete()
return redirect("/timeline/")
Forms:
class FollowForm(ModelForm):
class Meta:
exclude = set()
model = Follow
Urls:
path('follow/', login_required(views.follow), name='follow'),
path('unfollow/<target_id>/', login_required(views.unfollow), name='unfollow'),

{% if request.user in User.followers.all %}
