Form URL Error :Reverse for 'printReports' with no arguments not found. 1 pattern(s) tried

Question

我目前运行在尝试访问我的报告主页时出现上述错误。代码为 href="{% url 'printReports' reports_pk %}"

的表单的 'HREF' 部分似乎有问题

模板、视图和 URL 列在下面的代码中：

reportsHome.html :

{% block content%}
<h1 style=" text-align: center">Reports</h1>
<hr>
 <br>
 <div class="list-group">
     <a href="#" class='list-group-item active'>Print Single Complex's</a>
{% for x in model %}
    <a href="{% url 'printReports' reports_pk %}" class="list-group-item list-group-item-action" >{{ x.Complex }} Reports</a>
{% endfor %}
</div>
{% endblock %}

printPDF.html :

<title>PDF Outuput - TrialBalance</title>

{% block content%}
<h1 class = 'center'>Kyle Database Trial Balance</h1>
<br>

</div>
<br>
<br>

<div class="table-container">
  <table style="width: 100%">
    <th >Account</th>
    <th>Description</th>
    <th>Debit</th>
    <th>Credit</th>
    {% for arr_trbYTD in arr_trbYTD %}
      <tr>
        <td>{{ arr_trbYTD.Description }}</td>
        <td>{{ arr_trbYTD.Account }}</td>
        <td>
        {%if arr_trbYTD.Debit > 0%}
            {{arr_trbYTD.Debit}}
        {%endif%}
        </td>
        <td>
        {%if arr_trbYTD.Credit > 0%}
          {{arr_trbYTD.Credit}}

如果有人知道可能导致此错误的原因，请提供帮助

Answer 1

我假设 reports_pk 在你的模型中，所以我正在编辑它希望它能按照我的理解工作

{% block content%}
    <h1 style=" text-align: center">Reports</h1>
    <hr>
     <br>
     <div class="list-group">
         <a href="#" class='list-group-item active'>Print Single Complex's</a>
    {% for x in model %}
        <a href="{% url 'printReports' /{{reports_pk}} %}" class="list-group-item list-group-item-action" >{{ x.Complex }} Reports</a>
    {% endfor %}
    </div>
    {% endblock %}

Answer 2

如果 'model' 表示您的模型和模型的 x 元素，那么您可以使用 x.pk

访问主键

{% block content%}
<h1 style=" text-align: center">Reports</h1>
<hr>
 <br>
 <div class="list-group">
     <a href="#" class='list-group-item active'>Print Single Complex</a>
{% for x in model %}
    <a href="{% url 'printReports' x.pk %}" class="list-group-item list-group-item-action" >{{ x.Complex }} Reports</a>
{% endfor %}
</div>

{% endblock %}
