Dynamic generation of report using RML in OpenERP

Question

How to generate dynamic columns using RML report?

Answer 1

Read through the developer documentation on dynamic content in reports. You can use the repeatIn() function to loop over your dates, but the trick will be adjusting column widths. I suspect you can change the colWidths attribute of the table using the setTag() function.

Here's an example where I used it to change the table style.

    <section>
      [[ repeatIn(lines(data['form'],object=o), 'a') ]]
      <blockTable>
        [[ setTag('blockTable','blockTable',{'colWidths': '80.0,150.0,80.0', 'style': 'Table' + str(a['level'] if a['level'] &lt;= 5 else 5)}) ]] 
        <tr>
          <td lineAboveColor="#000000" lineAboveThickness="5" lineAboveCount="1" lineAboveSpace="5">
            <para style="P10"><font>[[ setTag('font','font',{'face':o.font_style or 'Helvetica', 'color':o.color_font.name or 'black', 'backColor':o.color_back.name or 'white'}) ]] [[ a['code'] ]]</font></para>
          </td>
          <td>
            <para style="P17"><font color="white">[[ '..'*(a['level']-1) ]]</font><font>[[ setTag('font','font',{'face':o.font_style or 'Helvetica', 'color':o.color_font.name or 'black', 'backColor':o.color_back.name or 'white'}) ]] [[ a['name'] ]]</font></para>
          </td>
          <td>
            <para style="P18"><font>[[ setTag('font','font',{'face':o.font_style or 'Helvetica', 'color':o.color_font.name or 'black', 'backColor':o.color_back.name or 'white'}) ]][[ '%.2f'% a['balance'] ]]</font></para>
          </td>
        </tr>
      </blockTable>
    </section>
