我有一個 Flask 模板，它顯示一個頁面，其中包含一個dropdown列表owners，一個table包含所有者的輸贏記錄，以及一個radio在regular賽季記錄和playoff記錄之間切換的頁面。所需的工作流程是：如果通過導航欄導航到頁面，它應該默認為/matchup-history/regular。（這有效）否則，無論何時radio切換，它都應該相應地路由。（這不起作用）比賽歷史.html{%- extends "base.html" -%}{% block nav_matchups %}active{% endblock %}{%- block content -%}  <form action="{{ url_for('show_matchup_history', matchup_type=request.form['matchup_type']) }}" method="post">    <label>      <select name="owner_id" onchange="this.form.submit()">      {%- for o in owners %}        {%- if request.form['owner_id'] == o['owner_id']|string() %}        <option value="{{ o['owner_id'] }}" selected>{{o['first_name'] + " " + o['last_name'] }}</option>        {%- else %}        <option value="{{ o['owner_id'] }}">{{o['first_name'] + " " + o['last_name'] }}</option>        {%- endif %}      {%- endfor %}      </select>    </label>    {% block matchup_type_radio %}{% endblock %}  </form>  {%- if records|length > 0 %}  <div class="stats-table">    <table>      <tr>        {%- for th in table_headers %}        <th>{{ th }}</th>        {%- endfor %}      </tr>      {%- for r in records %}      <tr>        {%- for cn in column_names %}        <td>{{ r[cn] }}</td>        {%- endfor %}      </tr>      {%- endfor %}    </table>  </div>  {%- endif %}{% endblock -%}比賽歷史/regular.html{%- extends "matchup-history.html" -%}{% block matchup_type_radio %}<label><input type="radio" name="matchup_type" value="regular" onclick="this.form.submit()" checked>Regular Season</label><label><input type="radio" name="matchup_type" value="playoffs" onclick="this.form.submit()">Playoffs</label>{% endblock %}比賽歷史/playoffs.html{%- extends "matchup-history.html" -%}{% block matchup_type_radio %}<label><input type="radio" name="matchup_type" value="regular" onclick="this.form.submit()">Regular Season</label><label><input type="radio" name="matchup_type" value="playoffs" onclick="this.form.submit()" checked>Playoffs</label>{% endblock %}
