How to get primary key from another table with one-to-many relationship in embedded code in django

Question

I'm not sure exactly how to ask this question, so apologies in advance if it doesn't make a lot of sense.

I'm creating a basic blogging-type website using pythonanywhere, and want each user to have a profile page. In the page that displays a list of all posts, I have the author of each post displayed like so in a

{% for post in posts %}:
    <p>author: {{ post.author }}</p>

Assuming that all my urls, views and templates are fine, how do I add a link to that text which would lead to /accounts/[user's id] ?

The Post model's author field is defined as

author = models.ForeignKey('auth.User')

Essentially I want:

<p>author: <a href="{% url 'account_detail' pk=User.pk %}">{{ post.author }}</a></p>

But I don't know how to actually get User.pk from post.author.

Answer 1

Assuming that you have this model:

author=models.ForeignKey('HERE IS ENOUGH THE MODEL)

and the ForeignKey is in a model named POST

for access the id of the table just write:

post.author__pk

By the way is always better do this operation in the view.py like:

value = post.objects.values('name', 'author__pk').filter(filter if necessary)

Answer 2

@Ivan Miljkovic的解释方式是，足以替换以下代码行：

<p>author: <a href="{% url 'account_detail' pk = post.author.pk %}">{{ post.author }}</a></p>
