如何在odoo中将域作为上下文传递

Question

我有一个["&",["customer","=",True],["type","=","contact"]]这样的域， 也具有类似{"lang":"en_US","tz":"Europe/Brussels","uid":2,"allowed_company_ids":[1],"params":{"action":157,"cids":1,"menu_id":112,"model":"crm.lead","view_type":"kanban"},"default_type":"opportunity","search_default_assigned_to_me":1}

的上下文

现在，我想做的是编辑域时，如果它包含'＆'，那么我们的上下文将是具有新域的前一个域（意味着上下文看起来像{"lang":"en_US","tz":"Europe/Brussels","uid":2,"allowed_company_ids":[1],"params":{"action":157,"cids":1,"menu_id":112,"model":"crm.lead","view_type":"kanban"},"default_type":"opportunity","search_default_assigned_to_me":1}, "default_customer": True, "default_type":"contact")，但是如果它包含“ |”，那么我们的上下文将是前一个（意味着现在上下文将看起来像{"lang":"en_US","tz":"Europe/Brussels","uid":2,"allowed_company_ids":[1],"params":{"action":157,"cids":1,"menu_id":112,"model":"crm.lead","view_type":"kanban"},"default_type":"opportunity","search_default_assigned_to_me":1}）。

谁能建议如何做...
