Issue a POST request with url_for in Flask

Question

I'm trying to issue a POST request within a Jinja template in Flask. However, parameters are passed in via GET by default, and this particular method only accepts POST requests.

I tried specifying _method, as below, but it still passes the parameter with GET instead of POST.

<li><a href = "{{ url_for('save_info', _method='POST', filepath=s.name ) }}"><div class="nodes">{{ s.title}} - {{ song.owner }}</div></a></li>

(The error message is the same whether or not I specify _method).

Answer 1

You can add a Middelway which search for a GET argument which overwrite the http method. Look there: http://flask.pocoo.org/snippets/38/

Your new link will look like this:

<li><a href = "{{ url_for('save_info', __METHOD_OVERRIDE__='POST', filepath=s.name ) }}"><div class="nodes">{{ s.title}} - {{ song.owner }}</div></a></li>
