Hello there. I am at a loss here on Odoo 14. I've added some fields to the model res.partner like this one: 

some_terms = fields.Text(string='Some extra Terms')

and then inherited it on sale.order like this: 

some_terms = fields.Text(related='partner_id.some_terms', string='Some extra Terms', store=True)

and now I would like to display these terms on a sales order if this text field is not empty. I managed to show the text from that field on the sales.order.form, and put it in a t-if-condition like this:

<t t-if="some_terms">

​<div class="alert alert-info">

​ ​<strong>Some Terms:</strong><br/>

​ ​<field name="some_terms"/>

​</div>

</t>


But Odoo always displays the div and the text no matter what! I've tried things like: 

t-if="some_terms and some_terms.strip() != ''"
t-if="some_terms not none"
t-if="true != true"

Even with the last condition that should stop anything from being displayed it shows the div. 

I appreciate any help or hint.

In my case, printing out the string representation helped. I could see that even an empty field had markup as the value. My field was defined in the model as fields.Html().

 Description repr: <t t-esc="repr(some_terms)"/>

<p><br></p>

From there, I was able to adjust the if conditions. As you can see, I had to change the tags to entity-encoded versions. Adding bare tags will throw a syntax error. Perhaps, there's a cleaner way of doing this.

xml.etree.XMLSyntaxError: Unescaped '<' not allowed in attributes values

 
Final solution:

​<t t-if="some_terms and some_terms.strip() != '&lt;p&gt;&lt;br&gt;&lt;/p&gt;'">

Well, since t-if-conditions are seemingly ignored altogether, can it be that t-if statements only work in certain areas or inheritance... levels or something?

I mean, I tried to put a t-if="1 == 2" in different parts of my xml file AND the original one and the containing string has always been displayed. Is there a general thing I am missing?

Try this  

  t-if="doc.some_terms != ''"

or this 

t-if="doc.some_terms"

Unfortunately this does not work, either.

Unfortunately it does not. But thank you. The weird thin ist, that t-if="some_terms" AND t-if="not some_terms" AND t-if="some_terms == ''" are all handled as true and all show their content no matter what.

if you want show this in qweb report, your code is right but in form view in odoo you should use attrs like: attrs="{'invisible': [('some_terms','=',False)]}"

But doesn't that only works with already displayed fields? Or do you mean, I have to have the fields hidden in the form and then... make the actually fields to be shown dependent on the content of their hidden copies? You know what I mean? When I use the attrs="{'invisible': [('some_terms','=',False)]}" on the surounding element, Odoo says that this field does not exist...

Can you share the full code? If I know the answer, I'll help.

Without knowing what report you are inheriting exactly it is tough to troubleshoot but try something like:

t-if="doc.some_terms"

The main Sales Order report is setup so that it can be looped through with several other Sales Orders. i.e. Select multiple Sales Orders and print in one click, hence the need to specify doc.xxxx

Beyond that make sure you are inheriting the template correctly.

Thank you, but I inherit <field name="inherit_id" ref="sale.view_order_form"/>.
