How can I affect individual entries in a django for loop?

Question

I have created a for loop in Django which displays articles uploaded by users. In the case of long articles I will truncate the text to a max length of 150 chars, but want to give readers the option of expanding the text using a jquery function, by clicking 'read more'. This is my template:

{% for post in posts %}
    {% if post.content|length > 150 %}
        <p class="half-content">{{ post.content|truncatechars:150 }}<a href="javascript:void();" class="show-hide-btn">read more</a></p>
        <p class="full-content" style="display: none;">{{ post.content }}</p>
    {% else %}
        <p>{{ post.content }}</p>
    {% endif %}
{% endfor %}

And here is my jquery function:

$(document).ready(function(){
    $(".show-hide-btn").click(function(){
        $(".half-content").hide();
    });
});
$(document).ready(function(){
    $(".show-hide-btn").click(function(){
        $(".full-content").show();
    });
});

It works how I would like it to, except that the 'read more' link is expanding all the articles on the page, not just the one with the appropriate primary key. I know I need to include {{ post.id }} in my code somewhere, but so far everything I have tried has been ineffective.

try this,

{% for post in posts %}
    {% if post.content|length > 150 %}
        <p class="half-content" id="half-{{post.id}}">{{ post.content|truncatechars:150 }}<a data-id="{{post.id}}" href="javascript:void();" class="show-hide-btn">read more</a></p>
        <p class="full-content" id="full-{{post.id}}" style="display: none;">{{ post.content }}</p></div>
    {% else %}
        <p>{{ post.content }}</p>
    {% endif %}
{% endfor %}


<script>
    $(document).ready(function(){
        $(".show-hide-btn").click(function(){
            var id = $(this).data("id");
            $("#half-"+id).hide();
            $("#full-"+id).show();
        });
    });
</script>
