Using ignore_permissions in set_value and commit


I try to update values of a doc from a public web_form.
In order to do this, in server side py file, I use frappe.set_value() and then frappe.db.commit().

The problem is a public web_form means the user is Guest. So it is not allowed to set_value and commit.
I am able to insert the new doc with

So… is there any way to use ignore_permissions with those set_value and db.commit?
Or is there any way to change Guest to any system user just to update the value?

Thank you

You could do

doc = frappe.get_doc(“DOCTYPE_NAME”, “DOCNAME”)

Hi @kartik,

Thanks for your input.
But my problem is not on the saving. I did saving with that lines.
My problem is after the doc is inserted, I run other process, and then a code to change the value of the doc.

So I run:

frappe.set_value(doctype, 'fieldname' , 'new_value')

This is where the problem arise. I got permission error:

File "/Users/rahy/frappe-bench/apps/frappe/frappe/", line 692, in set_value return frappe.client.set_value(doctype, docname, fieldname, value) 
File "/Users/rahy/frappe-bench/apps/frappe/frappe/", line 128, in set_value
File "/Users/rahy/frappe-bench/apps/frappe/frappe/model/", line 273, in save return self._save(*args, **kwargs)
File "/Users/rahy/frappe-bench/apps/frappe/frappe/model/", line 299, in _save self.check_permission("write", "save")
File "/Users/rahy/frappe-bench/apps/frappe/frappe/model/", line 180, in check_permission self.raise_no_permission_to(permlevel or permtype)
File "/Users/rahy/frappe-bench/apps/frappe/frappe/model/", line 194, in raise_no_permission_to raise frappe.PermissionError

This error occurs when set_value function is saving the doc because the guest user doesn’t have the permission to edit the doctype.
The above code snippet I shared is another way to do the exact same thing as frappe.set_value and you can pass the ignore permissions flag to save it.

Thanks @kartik
It works.
