While working on my website's HTML file, I encountered a challenge with nested for-loops. The first loop successfully checks the user's account and displays the corresponding data, and the second loop filters data starting with "Title:" and displays it flawlessly.
{% for item in user.Doc.all %}
However, when I tried to nest the loops to display specific content, it didn't work as expected. Even after researching different approaches, such as moving the logic to views.py instead of handling it in the HTML file, I couldn't find a solution that worked. Here is the code snippet that is causing trouble:
{% for item in user.Doc.all %}
{% for post in item.templates %}
{{ post.content }}
{% endfor %}
{% endfor %}
Despite adding conditionals before the loops, no data was displayed. I have explored resources like this and this, which mention forloop.parentloop, but the issue persists. Any guidance would be appreciated!
Below is an excerpt from my views.py showcasing the setup:
def docpostlistview(request):
docs = DocPost.objects.all()
context = {"docs": docs}
context['templates'] = DocPost.objects.filter(title__startswith="Temp: ")
return render(request, 'my_app/docpost_list.html', context)
EDIT:
class DocPost(models.Model):
user = models.ForeignKey(User, default=True, related_name="Doc", on_delete=models.PROTECT)
title = models.CharField(max_length=100)
content = HTMLField(blank=True, null=True)
class Meta:
ordering = ['-pk']
def __str__(self):
return self.title
def get_absolute_url(self):
return reverse('doc-post-list')
