I'm unable to use `for blocks` in custom print formats

Frappe Framework Print Formats
1

I’m trying to add the given custom HTML section in my print formats, but have something parsing my HTML, and breaking the template!

{% set sub_tables = frappe.get_list('DocField', fields=['fieldname', 'options', 'label'], filters={'parent': doc.name, 'fieldtype': 'Table'}) %} 

<table class="table table-bordered">
    <tbody>
{% for table in sub_tables %}
        <tr>
            <td>{{ table["fieldname"] }}</td>
            <td>{{ table["options"] }}</td>
            <td>{{ table["label"] }}</td>
        </tr>
{% endfor %}
    </tbody>
</table>

<!-- markdown -->

After the sanitization I’m getting it

{% set sub_tables = frappe.get_list('DocField', fields=['fieldname', 'options', 'label'], filters={'parent': doc.name, 'fieldtype': 'Table'}) %} 

<table class="table table-bordered">
    <tbody>
        <tr>
            <td>{{ table["fieldname"] }}</td>
            <td>{{ table["options"] }}</td>
            <td>{{ table["label"] }}</td>
        </tr>
    </tbody>
</table>
{% for table in sub_tables %}{% endfor %}

<!-- markdown -->

And this is chashing my templates!

See the trace in your bench console… we need to fix this since its an html trace

But the issue, is the HTML is being sanitized by the HTML editor

This was fixed by changing the fieldtype as “Code” for custom code Print Format.

7

@anand, I’ll check! You mean the field format_data? I’m using the Print Format Builder!

8

I presume this is not fixed. right? @max_morais_dmm were you able to find a work around for this issue? I’m trying to get tax break up to be printed in print format…

9

@kirthi, it is not fixed! Is a issue with print formats in Print Format Builder

I create standards print formats, using jinja templates! Choosing the format of the print format for Server

Thanks @max_morais_dmm
