How can i preset the field value (from parent entity) of a child entity when create

[Vincent]

I have 2 entities mstr and dtl and the relationship between mstr and dtl is One-to-Many.

I add dtl to the relationship panel in mstr.
I want to preset the value of dtl (value from mstr) in dtl create page. how can i do this? thanks

Hello,
if you create dtl with the relationship panel, and mstr field is on the detail (small), this field will be filled

Thanks.

I want field A of dtl to be filled by he name of the mstr when create. how can i do this, thanks.

If you want to fill this field on the editable form, you need to develop it (override the view of mstr field , 'select' method)
(
client/modules/advanced/src/views/quote/fields/account.js if you have Advanced Pack

https://www.espocrm.com/documentation/development/custom-views/#user-content-field-views

)

If you want only to show the field of related entity, you can create a field with the type Foreign in Entity Manager and the field of related entity will be shown on the form, but won't be editable (readOnly)

Thanks.

I tried Foreign field. When creating the dtl record using relationship panel, the mstr is shown in the create view of the dtl , but the field A shows None.
After the dtl record is saved, field A is filled. But i want the field A is filled before save.

i have also tried overriden the view of mstr field of dtl entity, 'select' method. But the mstr value is auto-filled by the system when i creating a new dtl record using relationship panel, select method has not been run.

relatedAttributeFunctions method in views/campaign/detail.js show the example of how to set the value from mstr to dlt when create
