how to get value of a field in fields_view_get? - odoo

Question

I want to get a value of a field in fields_view_get method in openerp 7.0.
I tried the following:
1- send the value of the field in the context attribute as following:
< field name="employee_id" context="{'employee_id':employee_id}" />
and in the fields_view_get I get it as following:
print "employee_id in the context value is %s"%(context.get('employee_id', False))
but it always the the context.get(...) returns False. so I tried the following:
2- on the onchange method of the field I send the value of the field in the context as following:
def onchange_employee_id(self, cr, uid, ids, employee_id):
return {'context': {'employee_id': employee_id}}
and in the fields_view_get I get it as following:
print "employee_id in the context value is %s"%(context.get('employee_id', False))
but also the same thing always the context.get(..) returns False.
How can I get the value of a field in fields_view_get function ?

Maybe this answer is too late for you, but perhaps someone will find it useful.
If you need the dynamic view just on form view, you should write a tree view and you can put the selected record id to the context...so with the context id, you can read the fields.
But fields_view_get is not too easy. Dont forget about update the return dictionary (the two very important keys: fields, arch).
If you want to use invisible or readonly tag, you should use modifiers tag like attrs.
Example:
def fields_view_get(self, cr, uid, view_id=False, view_type='tree', context=None, toolbar=False, submenu=False):
fields = self.read(cr, uid, context['working_id'], [])
actualView = super(ModelName, self).fields_view_get(cr, uid, view_id, view_type, context, toolbar, submenu)
# you can write default view in xml and dynamic complete with some field in this method
actualView['fields'].update({'field_name':{'type': 'text', 'string': 'Name'}})
arch = minidom.parseString(actualView['arch'])
#for example: triggered to <newline/> field
newlineField = arch.getElementByTagName('newline').item(0)
element = arch.createElement('field_name')
element.setAttribute('name', 'Name')
newlineField.insertBefore(element, 0)
actualView['arch'] = arch.toxml("utf-8")
return actualView
