I’ve two models which display in the same panel in admin using TabularInline
models.py
class Multimg(models.Model):
post = models.ForeignKey('Post', null=True, blank=True, on_delete=models.CASCADE)
caption = models.TextField(max_length=50, null="true", blank=True)
text = tinymce_models.HTMLField(null="true")
multimg = models.ImageField(upload_to="images", verbose_name='Image', null="true", blank=True,)
class Post(models.Model):
title = models.CharField(max_length=50)
highlight = models.TextField(max_length=250, null="true", blank=True,)
image_article = models.ImageField(upload_to="images", verbose_name='Image', null="true")
date_posted = models.DateTimeField(default=timezone.now)
author = models.ForeignKey(User, on_delete=models.CASCADE)
admin.py
class MultiAdmin(admin.TabularInline):
model = Multimg
extra = 3
@admin.register(Post)
class PostAdmin(admin.ModelAdmin):
model = Post
inlines = [ MultiAdmin ]
I want to display the objects of these two models in the same details template and filter their objects to display based on the Post.id
I’m using get_context_data to display the element of the Multimg Model
the Post model is causing no problems But when I try to display the Multimg object I cannot display the objects related only to the post details
views.py
class PostDetailView(DetailView):
model = Post
template_name = 'blog/post_detail.html'
def get_success_url(self):
return reverse('post-detail', kwargs={'pk': self.object.id})
def get_context_data(self, **kwargs):
context = super(PostDetailView, self).get_context_data(**kwargs)
context['posts'] = Post.objects.all()
context['multimgs'] = Multimg.objects.all()
return context
post_detail.html
<h1>{{ post.title }}</h1>
<p> {{ post.author }}</p>
<p> {{ post.date_posted|date:"M d, Y" }} </p>
{% if post.image_article %}
<img src="{{ post.image_article.url }}">
{% endif %}
{% for multimg in posts %}
<p> {{ multimg.caption }}</p>
<p> {{multimg.text|safe }}</p>
{% if multimg.multimg %}
<img src="{{ multimg.multimg.url }}">
{% endif %}
{% endfor %}
I’m able to display all its object using the tag {% for multimg in multimgs %} but when I try to display only the objects related to that particular post detail using {% for multimg in posts %} I display nothing.
I’m assuming the context is not able to make a relationship between that particular detail post and the object of this model but I’m confused about the approach I should use in order to achieve that. Can someone help with this?
