How do you make a field conditionally read only?

Question

I thought I had seen a post about making a field read only if a certain condition were true, but now I can't find that post.  This is what I'm trying:

(This is in the sale order lines tree.)  I'm getting this error:

Error: Unknown field S in domain ["product_id.name_template","!=","Shipping"]

Do I just have a syntax problem, or am I just going about this the wrong way?

You getting error because you've used dot notation to access other fields then actually presented in the view ( you can't use: /['product_id.name_template','!=','Shipping']/  you can use only: ['product_id','!=','something'] ), as this is parsed at client side you can use only those fields taht are presented in the view. So in order to get it worked, you can add to the model a relational field that points to 'product_id.name_template' than add this field as invisible field to the view and you'll

'name_template' : fields.related('product_id','name_template', type='char', string='Name Template',store=True),

Create this related field field in the sale.order.line  .py file and make the field as *invisible* in the view.

Just checks:

attrs="{readonly': [('name_template','!=','Shipping')]}"

( Note:

In v8 you can use this:

name_template= fields.Char(related='product_id.name_template', store=True, readonly=True) )

This can help you
