Querying related fields from Django Tables with One to Many Relationship – Photoshop

I am just exploring how to get around with Django, and i created two models in my Django app.

from django.db import models

#first model
class Person(models.Model):
    name = models.CharField(max_length=40)
    email = models.CharField(max_length=100)
    title = models.CharField(max_length=100)
    image = models.CharField(max_length=200)

    def __str__(self):
         return self.name

#second model
class Skill(models.Model):
    person = models.ForeignKey(Person)
    skill = models.CharField(max_length=60)
    years = models.CharField(max_length=40)

    def __str__(self):
        return self.skill, self.person

The first model is Person and the second model is Skill. Now how the relation goes is that each Person will have many skills.

Now I can update the database with the data, the admin section of the site also works fine.

On the Django Shell, I try to run the command:

Skill.object.all()

and what i get is the following error:

Traceback (most recent call last):

File "<console>", line 1, in <module>
  File "C:Program Files (x86)Python36-32libsite-packagesdjangodbmodelsquery.py", line 235, in __repr__
    return '<QuerySet %r>' % data
  File "C:Program Files (x86)Python36-32libsite-packagesdjangodbmodelsbase.py", line 572, in __repr__
    u = six.text_type(self)
TypeError: __str__ returned non-string (type tuple)

or if i try the command:

Skill.objects.get(pk=1)

i get:

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "C:Program Files (x86)Python36-32libsite-packagesdjangodbmodelsbase.py", line 572, in __repr__
    u = six.text_type(self)
TypeError: __str__ returned non-string (type tuple)

However if i run a command such as :

 Skill.objects.get(skill='Photoshop').person.name

I get the name of the person who has the skill “Photoshop.”

I am trying to understand what I am doing wrong here; maybe I am not supposed to query a table with the foreign key this way? Or maybe I am doing something wrong.

Well, finally what I like to query is, I want to find all the skills of a Person with a given name or primary key.
