QuerySet不呈现

Question

I have a QuerySet that I can see via print has items

<QuerySet [<Task: 1|root|test_task2>, <Task: 2|root|asdf>, <Task: 3|root|asdfafd>, <Task: 5|root|asdfasdfwe>, <Task: 6|root|asdfasdf>]>

which when I then try to render in template via:

return render(request, 'tasks.html',{'tasks:': tasks})

template:

{% for task in tasks %}
    <tr>
        <td>{{ task }} <a href=/tasks/edit/{{ task.id }}>edit</a> <a href=/tasks/delete/{{ task.id }}>delete</a> <a href=/tasks/mark_done/{{ task.id }}>mark_done</a></td>
    </tr>
{% endfor %}
shows up as if tasks was None
<table>

Answer 1

Late night typo

See {'tasks:': tasks}

should be {'tasks': tasks}
