OpenERP: Use field value in attribute of html tag in form view

Question

is it possible to use a field from the model as attribute inside an html tag.

Specifically in a form view I would like to create a link to an external issue tracker from the issue number taken from my model. I would like to display the issue number as link text with the full URL as external target.

Like that:

<a href="www.example.com" target="_blank"><field name="issue_nr" nolabel="1"/></a>

This is working nicely so far as I get a link to the URL displayed with the issue number as label and in edit mode I get a text field where I can change the issue number itself.

My problem is that I don't know how to set the href attribute dynamically. The idea would be to get the link build by a dynamic field. I tried this and it is working well, but I don't know how to get the content of that dynamic field inside the href attribute of the anchor.

Any ideas? I don't necessarily need a field for href. If it's possible to do this with python code, that would be fine too.

Thanks and regards,

Peter

I suggest adding a functional field in your model in python:

def _generate_href(self, cr, uid, ids, field, arg, context=None):
    res = {}

    for id in ids:
        issue = self.browse(cr, uid, id)
        res[id] = "http://example.com/" + str(issue.issue_nr)

    return res

_columns = {
    #...
    href_link: fields.function(_generate_href, type="char", size=128, string='Web address')
    #...
}

And then in your view you can do this:

<field name="href_link" nolabel="1" widget="url" readonly="1"/>
