How to delete items from database using a Flask framework?

Question

I'm working with a Flask framework, and am trying to delete an entry from the database. The code below gives this error: "The method is not allowed for the requested URL."

In the html:

<form action="{{ url_for('delete_entry', id=entry.id) }}" method="POST">
     <input type="hidden" name="_method" value="DELETE" />
     <input type="submit" value="Delete entry" />
</form>

In the py:

@app.route('/delete', methods=['DELETE'])
def delete_entry(postID):
    if not session.get('logged_in'):
        abort(401)
    g.db.execute('delete from entries WHERE id = ?', [postID])
    flash('Entry was deleted')
    return redirect(url_for('show_entries'))

How do I then get the correct postID from the html to the py?

If you are going to use a POST request the variable will be available under flask's request.form. If you stay with DELETE I think you need to change your uri. For example:

@app.route('/delete/<int:postID>', methods=['DELETE'])
