I found a better way to solve the problem by adding additional function in the models.py file

models.py

def tags_list(self):
    return self.tags.split(',')

template.html

{% for tag in tags_list %}
    <p>{{ tag }}</p>
{% endfor %}

simple and easy!

In your view, split the comma value CharField field like this:

class ProfileView(CanEditMixin, UserPassesTestMixin, DetailView):
    template_name = "profile/profile_view.html"
    queryset = User.objects.all()
    context_object_name = 'profile'
    slug_field = "username"`

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)  # get parent context
        # the model here should be replaced with the object that has the "tag" attribute. DO NOT use the "model" word.
        # Try self.object.tag.split(',')
        tag_list = model.tag.split(',')  # conversion from a string to a list
        context['tag_list'] = tag_list  # add to the context the tag_list list
        return context

and then in your template simply iterate over it:

{% for tag in tag_list %}
    <p>{{ tag }}</p>
{% endfor %}

The correct way works, but I would use the list built-in method to just change the string from array.

class MyModel(models.Model):
    string_array = models.CharField(max_length=100)

    def pass_to_list(self):
        return list(self.string_array)

Notes:

• Remember that your string array must be an actual array on the database, with '[' and everything
• This way works by taking use of the built-in list method, but you can also just return the string splitted by commas
