Issue
I have two seperated models. One with two text fields and one for multiple images. Now I want to display the entire data in one html div. What do I have to change in the projects view and in projects.html?
models.py
class Project(models.Model):
title = models.CharField(max_length=200)
describtion = models.TextField(null=True, blank=True)
class ProjectImage(models.Model):
project = models.ForeignKey(Project, on_delete=models.CASCADE)
image = models.FileField(upload_to="products/")
forms.py
class ProjectForm(forms.ModelForm):
class Meta:
model = Project
fields = ['title', 'describtion']
class ProjectImageForm(forms.ModelForm):
class Meta:
model = ProjectImage
fields = ['image']
widgets = {
'image': ClearableFileInput(attrs={'multiple': True}),
}
views.py
def createProject(request):
form = ProjectForm()
form2 = ProjectImageForm()
if request.method == 'POST':
form = ProjectForm(request.POST)
form2 = ProjectImageForm(request.POST, request.FILES)
images = request.FILES.getlist('image')
if form.is_valid() and form2.is_valid():
title = form.cleaned_data['title']
describ = form.cleaned_data['describtion']
project_instance = Project.objects.create(
title=title, describtion=describ)
for i in images:
ProjectImage.objects.create(project=project_instance, image=i)
context = {'form': form, 'form2': form2}
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)
projects.html
{% for project in projects %}
<div class="column">
<div class="card project">
<img class="project__thumbnail" src="{{project.image.url}}" alt="project thumbnail" />
<div class="card__body">
<h3>{{project.title}}</h3>
<h2>{{project.describtion}}</h2>
</div>
</a>
</div>
</div>
{% endfor %}
Solution
You don't need to change anything.
You should be able to access the reverse with project.project_image_set
attribute in the template:
<div class="card__body"
<h3>{{project.title}}</h3>
<h2>{{project.describtion}}</h2>
{% for image in project.project_image_set.all %}
{{ image.image }}
{% endear %}
</div>
