I have a question regarding the use of genshi.
I want to make a hyperlink to a sale in an email template in order to redirect users to it. I want to do it directly on the text field throughout the user interface like this:
Could you explain precisely what you did, what did not work and what was the result and why it is not what you expect?
I expect to get a hyperlink to a sale, that this hyperlink has to appear at the body of the email template.
I tried the code that you can see on the picture. And when the mail arrives all that expression it’s literally a text, no hyperlink. And idk if there is way to do it.
The second thing that I need to do, is to take the shipments of a sale and iterate between them to get their numbers and show them on the body too, without creating a function field to get that.
The richtext widget does not support anchor element.
You can loop with the genshi text directives: https://genshi.readthedocs.io/en/latest/text-templates/#looping
I tried to do that:
{% for shipment in ${record.shipments} %}\
${shipment.number}
{% end %}
But it results in an error when I open the email template from the sale.

I think it is your subject rendering that is failing not the body.
Is this maybe related to Tryton is using the OldTextTemplate instead the NewTextTemplate (#11737) · Issues · Tryton / Tryton · GitLab? It means that the old syntax has to be used (https://genshi.readthedocs.io/en/latest/text-templates/#legacy-text-template-syntax).
It’s definitely related. But I tried to do a test using the OldTextTemplate with that:
#for item in [1, 2, 3]
* $item
#end
And the same error results, as the other I posted.
genshi.template.eval.UndefinedError: "item" not defined
I replaced the import that you mention in the issue
from genshi.template import TextTemplate -----> from genshi.template.text import NewTextTemplate as TextTemplate
Did the following, and it worked. But I would like to know if if i’m doing something wrong using the OldTextTemplate.
{% for shipment in record.shipments %}
$shipment.number,
{% end %}
I want to make a oneline if with OldTextTemplate, how can I do it? Because I don’t find a lot references in the documentation. I tried with this, but if there is no project, it throws an error.
#if ${record.project} ${record.project.rec_name} #end
Hi,
Just testing email templates and trying to do a loop on purchase lines in the body.
Here’s the body of my template:
Test Purchase: ${record.rec_name} → Ok Working
${record.lines[0].product.rec_name} → Ok Working
Not working:
{% for line in ${record.lines} %}
${line.product.rec_name} - ${line.quantity} - ${line.unit.rec_name}
{% end %}
I’m getting this error:

What is the correct syntax for a loop in template ?
What about this issue Migrate from OldTextTemplate to NewTextTemplate of Genshi (#9751) · Issues · Tryton / Tryton · GitLab ?
Did you try to use the # format like
#for line in record.lines
${line.product.rec_name} - ${line.quantity} - ${line.unit.rec_name}
#endStill the same error…
