Hello,
I have an html field and I want to display the field on Qweb report if it is not empty.
python code:
note= fields.Html(string="Note")
Qweb:
<p t-if="doc.note">
<strong>Note: </strong>
<span t-raw="doc.note"/>
</p>
if the the field is empty I got always the result:
Note:
Which is not as should be expected, I don't know if t-if tag is working on html.fields, please help !
Best regards
You need to escape the < > in XML.
For me the following works:
<div t-if="html-field != '<p><br></p>'">
</div>
There is a better way nowadays :
<p t-if="not is_html_empty(doc.payment_term_id.note)">
<strong>Note :</strong>
<span t-field="doc.payment_term_id.note"/>
</p>
Try
<div t-if="doc.note != '<p><br/></p>'">
<strong>Note: </strong>
<span t-raw="doc.note"/>
</div>
Have you tried this ?
Hi,
Since Odoo V14 there is a new helper called "is_html_empty". This built-in helper in the Odoo core now allows you to check if a field is empty or not. You can use this "is_html_empty" function in QWeb statements. You can then simply wrap this in a t-if statement as such: "t-if="is_html_empty(doc.note)" and do a t-else statement for example.
P.S: Sorry I wanted to paste a whole code block sample but sadly the official forum editor is completely broken again. You can see a sample in the core from Odoo here
Does this work for mail.template?
Trying to make a template that fills note field from a module if not empty. Still haven't found a way to make it work if it matches '<p><br></p>' aswell.
I mean for UI web template editor*
HI Jean
You just try <span> or <div> tag instead of <p> tag
I mean,
<span t-if="doc.note">
<strong>Note: </strong>
<span t-raw="doc.note"/>
</span>
or
<div t-if="doc.note">
<strong>Note: </strong>
<span t-raw="doc.note"/>
</div>
This how Odoo does it, did you try their method?
https://github.com/odoo/odoo/blob/11.0/addons/website_quote/views/website_quote_templates.xml#L649
<div t-field="option_line.website_description" class="oe_no_empty"/>

salam jean44;
in order to check if the html.field is empty you need to add this code:
<t t-foreach="docs" t-as="doc">
<t t-if="doc.html.field == '<br>'">
<t t-set="style" t-value=" 'display: none;' "/>
</t>
<span t-att-style="style" t-raw="html.field"/>
</t>
where <br> is <br> decoded
