How to remove empty values from jinja2?-CodePudding

{% for vul3 in vul["ports_data"] %}

   <td>{{ vul3["vulnerabilities"]["vulners"] }}</td>

{% endfor %}

Im getting a lot of empty values from the output which is filling my table with empty results, Anyway to get rid of it? I only wanna show the values which exist.

Empty Table Data

CodePudding user response：

Test the trimmed length of your field to exclude empty cells.
You can also test for None simply doing if vul3.vulnerabilities.vulners.

Those two together:

{% for vul3 in vul.ports_data %}
  {% if vul3.vulnerabilities.vulners 
        and vul3.vulnerabilities.vulners | trim | length 
  %}
    <tr>
      <td>{{ vul3.vulnerabilities.vulners }}</td>
    <tr>
  {% endif %}
{% endfor %}

CodePudding user response：

So this would be the answer, It cuts out all the empty values

    {% for vul3 in vul.ports_data %}
  {% if vul3.vulnerabilities.vulners 
        and vul3.vulnerabilities.vulners | trim | length 
  %}
    <tr>
      <td>{{ vul3.vulnerabilities.vulners }}</td>
    <tr>
  {% endif %}
{% endfor %}
