title: OpenERP: Use field value in attribute of html tag in form view
body: <p>is it possible to use a field from the model as attribute inside an html tag. </p>
  
  <p>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. </p>
  
  <p>Like that:  </p>
  
  <p><code>&lt;a href="www.example.com" target="_blank"&gt;&lt;field name="issue_nr" nolabel="1"/&gt;&lt;/a&gt;</code></p>
  
  <p>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. </p>
  
  <p>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. </p>
  
  <p>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. </p>
  
  <p>Thanks and regards, </p>
