class TaskList(LoginRequiredMixin, ListView):
    model = Task
    context_object_name = 'tasks'

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)

        return context

    title = models.CharField(max_length=200)
    description = models.TextField(null=True, blank=True)

{% else %}
#<a href="{% url 'login' %}">Login</a>new users can only put 2 links in a post.

{% endif %}


<h1>My to do list {{color}} </h1> 
<td><a href="{% url 'task-create'  %}">Add</a> </td>


        {%for task in tasks%}
        <td><a href="{% url 'task' %}">View</a> </td>
        <td><a href="{% url 'task-update' %}">Edit</a> </td>
        <td><a href="{% url 'task-delete' %}">Del</a> </td>
        <h3>No items in a list </h3>

can’t render specific data from user ,any help will be appreciated

First a side note, it should be backtick characters - ` not apostrophies - ' surrounding your code. I’ve gone ahead and fixed them for your initial post here. (You also had a couple cases of spaces within those lines, those won’t work either.)

Briefly, it doesn’t look like you’re assigning the current user to the user field within the model when you create the Task. See the docs and the examples at Creating forms from models | Django documentation | Django

In terms of doing this within a class-based view, you’re likely to want to override the form_valid method of the class. See the docs and examples at Form handling with class-based views | Django documentation | Django
