如何使bootstrap-table-filter-control与Flask、Jinja和Dataframe一起工作。

问题描述 投票：0回答：1

我使用python Flask render_template为我的python应用的路由返回一个html页面，在html中我想使用bootstrap-table-filter-control，就像bootstrap中描述的那样。例子. 然而，所给出的例子似乎是使用本地json文件中的一个表。下面是例子中给出的代码。

<link href="https://unpkg.com/[email protected]/dist/bootstrap-table.min.css" rel="stylesheet">

<script src="https://unpkg.com/[email protected]/dist/bootstrap-table.min.js"></script>
<script src="https://unpkg.com/[email protected]/dist/extensions/filter-control/bootstrap-table-filter-control.min.js"></script>

<table
  id="table"
  data-url="json/data1.json"   ## this looks like the code to get the table's data
  data-filter-control="true"
  data-show-search-clear-button="true">
  <thead>
    <tr>
      <th data-field="id">ID</th>
      <th data-field="name" data-filter-control="input">Item Name</th>
      <th data-field="price" data-filter-control="select">Item Price</th>
    </tr>
  </thead>
</table>

<script>
  $(function() {
    $('#table').bootstrapTable()
  })
</script>

我如何替换

data-url="jsondata1.json"

用我自己的表从main.py应用中传递过来的Python数据框架？我尝试了下面的html，但没有成功。

        {% for table in tables %}
            <table id="table"
                data = {{ table|safe }}
                data-filter-control="true"
                data-show-search-clear-button="true"
                class="table-striped">

                <thead>
                    <tr>
                        <th data-field="columnA" data-filter-control="input">column A</th>
                        <th data-field="columnB" data-filter-control="select">columnB</th>
                        <th data-field="columnC" data-filter-control="select">columnC</th>
                    </tr>
                </thead>
                <tbody>
                   <!-- I have tried to put {{ table|safe }} here but doesn't work -->
                </tbody>
            </table>
        {% endfor %}

我的python路径是这样的：

@app.route('/')
def hello():
    return render_template('yield.html',  tables=[df3.to_html(classes='data', header="true")])

其中df3是数据框，我想在yield.html中以表格形式显示，并使用bootstrap过滤控件。

python html flask jinja2 bootstrap-table

经过一些返璞归真的一步步测试，我找到了自己的解决方案，现在工作得很好。我的yield.html看起来是这样的，启用了bootstrap-table过滤控件、搜索和排序。

值得注意的是，我没有在main.py应用中调用由to_html制作的整个表格（dataframe到完整的html表格，包括表头和行标签），而是要特别指定表头（在ad标签内），每个列的参数都要说清楚，表头的数据字段名不允许有空格和特殊字符，然后用{% for row in tableA %}与相应的列名拉入数据行。

在我的python应用中，我的数据来自于数据框，我需要将其转换为python的数据类型，特别是像列表一样的python字典，用 data = df.to_dict('records') 当我渲染模板的时候，我可以通过使用 return render_template('yield.html', tableA = data)

我的python应用路线是这样的。

@app.route('/')
def hello():
    data = df.to_dict('records')
    return render_template('yield.html', tableA = data)
