Question

我有一个Flask应用程序，其路由使用分页并且必须处理GET和POST请求。我为我的函数定义了两个路由，如here所述让分页工作。

当我在第一页以外的页面上发布表格时，我会得到一个

“405 - 方法不允许”错误。

我该如何处理？我正在使用peewee作为我的数据库。

这是烧瓶应用代码：

@app.route("/tiles/failed", defaults={"page": 1}, methods=["POST", "GET"])
@app.route("/tiles/failed/page/<int:page>", methods=["POST", "GET"])
def tiles_failed(page):
    if request.method == "POST":
        process_id, tile_name = request.form["tile_name"].split("/")
        select_status = request.form["select_status"]
        if not select_status == "False":
            process = models.Process.select().where(models.Process.id == process_id).get()
            tile = models.Tile.select().where(models.Tile.name == tile_name and models.Tile.process == process).get()
            tile.message = "Manual state change from '{from_state}' to '{to_state}'".format(from_state=tile.success,
                                                                                            to_state=select_status)
            tile.success = select_status
            tile.error_count = 0
            tile.save()
    all_tiles = models.Tile.select().where(models.Tile.success == "False").order_by(models.Tile.name, models.Tile.process)
    count = all_tiles.count()
    tiles = get_tiles_per_page(all_tiles, page, TILES_PER_PAGE, count)
    if not tiles and page != 1:
        abort(404)
    pagination = Pagination(page, TILES_PER_PAGE, count)
    t = app.jinja2_env.get_template("tiles.html")
    return t.render(tiles=tiles, pagination=pagination, count=count, request=request)

这是相关的HTML代码段：

<form name="select_form" method="post">
  <select name="select_status" onchange="if(confirm('are you sure?')){this.form.submit();}else{selectFalse();}">
    <option value="False" selected>False</option>
    <option value="True">True</option>
    <option value="pending">pending</option>
  </select>
  <input type="hidden" name="tile_name" value="{{ tile.process.id }}/{{ tile.name }}" />
</form>

希望这能解释我的问题。提前谢谢！

您的表单必须具有action属性，该属性指向处理表单的函数。在您的情况下，此函数为tiles_failed：

<form action="{{ url_for('tiles_failed') }}" name="select_form" method="post">
