Buttons in table. Which row was selected to export.

[gontajones]

I think you'll have to do something like:

{% for pdf_store in display_pdf_store %}
<tr onclick='highlight()'>
<form action='/download_pdf'>
<td> {{ pdf_store.product_serial_number}} <input type="hidden" name="product_serial_number" value="{{ pdf_store.product_serial_number}}" /> </td>
<td> {{ pdf_store.doctype}} <input type="hidden" name="doctype" value="{{ pdf_store.doctype}}" /> </td>
<td> {{ pdf_store.date_time}} <input type="hidden" name="date_time" value="{{ pdf_store.date_time}}" /> </td>
<td> {{ pdf_store.place_of_procedure}}  <input type="hidden" name="place_of_procedure" value="{{ pdf_store.place_of_procedure}}" /></td>
<td><input type='submit' id='Export' value='Export'></input></td>
</form>
</tr>
{% endfor %}

Or use JQuery to get the content of the row and pass it to the backend (AJAX?).
Just a start...

HTML:

{% for pdf_store in display_pdf_store %}
<tr onclick='highlight()'>
<td> {{ pdf_store.product_serial_number}}</td>
<td> {{ pdf_store.doctype}}</td>
<td> {{ pdf_store.date_time}}</td>
<td> {{ pdf_store.place_of_procedure}}</td>
<td><button type="button" value="export_pdf" class="export_pdf" /></td>
</tr>
{% endfor %}

JS:

$(".export_pdf").click(function() {
    var $tds = $(this).closest("tr").find("td");
    $.each($tds, function() {
        alert($(this).text());
    });
});
