Hi, everyone

I would like to automatically apply a Pricelist assigned to a web user when they log in
Therefore I've created a custom field in contacts that could select one of the pricelists

- Model: pricelist = fields.Many2one('product.pricelist', string='Pricelist')

- XML:  field name="pricelist" string="Pricelist"

I've made it this far, but I don't know what to do next
I think I need to control it with JavaScript, but I have no idea how to approach it

Can anyone give me some tips on how to find the web template id and how to code the javascript?

Many thanks
