django get和post報錯

get：

    <form action="/def_search_get" method="get">
{#        action中填後臺對應的 get/post方法名#}
        <input type="text" name="q">
        <input type="submit" value="搜索">
    </form>

post：

    <form action="/def_search_post" method="post">
        {% csrf_token %}
        <input type="text" name="q">
        <input type="submit" value="Submit">
    </form>

其他路徑都一樣
報錯：RuntimeError: You called this URL via POST, but the URL doesn’t end in a slash and you have APPEND_SLASH set. Django can’t redirect to the slash URL while maintaining POST data. Change your form to point to 127.0.0.1:8000/def_search_post/ (note the trailing slash), or set APPEND_SLASH=False in your Django settings.
辦法：form中給post方式的路徑末尾加/
即：

<form action="/def_search_post/" method="post">
