The templatetag {% include %} in Django

Loads a template and renders it with the current context.

# 會把 template context 也帶進去
{% include 'new_style/_bottom_action_btns' %}

{% for repost in recommend_creatives %}
    # 會把 repost 這個參數也帶進去!
    {% include 'new_style/creative_small.html' %}
{% endfor %}

# 但是你也可以額外指定要傳進去的 context
{% include 'new_style/_bottom_action_btns' with item=item repost=None %}

# 或是用 only 來限制只傳「顯式地指定的參數」進去
{% include 'new_style/_bottom_action_btns' with item=item only %}
