Using the 'for' loop in django tags for 'ForeignKey'
My django loop in the templates does not work correctly. Why, because of me, everything looks good?
Any help will be appreciated.
My models.py
class Tags(models.Model):
name = models.CharField(max_length=10)
class Person(models.Model):
keywords = models.ForeignKey(Tags, on_delete=models.CASCADE)
My views.py
def person_detail(request, user_id):
person = get_object_or_404(Person, pk=user_id)
context = {'person': person}
return render(request, 'person_detail.html', context)
My templates.html
{% for tag in person.tags %}
<span class="badge badge-lg badge-pill badge-info"># {{ person.tags.name } </span>
{% endfor %}
This gives no results even though there is data in the database.

It doesn't matter @JohnGordon , it's not possible to loop over it, theperson.keywordswill just return an instance ofTags, you could useManyToManyField, or you may use theForeignKeyfield in Tags model instead

You are doing it backwards. Your Tags model should have a foreign key to Person, not the other way around. For example:
class Person(models.Model):
...
class Tag(models.Model):
person = models.ForeignKey(Person, on_delete=models.CASCADE)
name = models.CharField(max_length=10)
Note that I've also renamed your Tags model to Tag as it makes sense to name models singular.
Then you can write the following:
{% for tag in person.tag_set.all %}
...
{% endfor %}

Where can I find more information about something like 'tag_set.all'? I wonder if I can do the same in such an easy way, eg 1 tag added, or first added photo? something like '{% for tag in person.tag_set.first%}'
