Я пытаюсь вызвать функцию для записи файла, но мой Django url.py похоже, вызывает функцию markdown. Когда вы нажимаете кнопку отправить на форме в HTML, вы получаете сообщение об ошибке, которое выдает строку «если запрос[«q»] в записях:»

HTML

 <h1>New Page</h1>


<form action="{% url 'newPage'}" method="POST">
    {% csrf_token %}
    <div class="form-group">
        <label for="title">Title</label>
        <input type="text" class="form-control" id="title" name="t" placeholder="Title">
    </div>
    <div class="form-group">
        <label for="content">Content</label>
        <textarea class="form-control" id="content" rows="10" name="c" placeholder="Markdown content"></textarea>
    </div>
    <button type="submit" class="btn btn-primary">Submit</button>
</form>
