Passing Django Model to Template

I have a little problem which I can't seem to get my head around. It seems like a very trivial thing but I just can't figure it out. Essentially what I'm trying to do is to create a Project model which holds information on a certain project and then have another model called Link which holds the name of the link such as 'Get Program' or 'Download Release' and have a URLField which holds the URL for those links and is child of Project.

So far my models.py is as below:

from django.db import models

class Project(models.Model):
    name = models.CharField(max_length=255)
    description = models.TextField()

    def get_name(self):
        return self.name

    def get_description(self):
        return self.description

    def __str__(self):
        return self.name

class Link(models.Model):
    project = models.ForeignKey(Project)
    name = models.CharField(max_length=255)
    url = models.URLField()

    def get_name(self):
        return self.name

    def __str__(self):
        return self.name

Problem is in my views.py I want to be able to pass Projects object so I can iterate over them and display all links for each project including the project objects fields such as name and description. So far I've done:

from django.shortcuts import render
from django.http import HttpResponse
from .models import Project, Link

def projects_index(request):

    projects = Project.objects.all()
    links = Link.objects.all()

    context = {
        'projects': projects,
    }
    return render(request, 'projects.html', context)

You really should do the tutorial. 

for project in projects:
    for link in project.link_set.all:
        <...>

Add a related_name="links" to your foreign key, and the inner loop can be

for link in project.links:

Inside your template projects.html you should be able to loop over the Links for each project with

{% for project in projects %}
  {% for link in project.link_set.all %}
      {{ link }}
  {% endfor %}
{% endfor %}
