What is computed field in Odoo?
A computed field is declared just like any other regular field in Odoo along with the additional argument compute. The value is the name of the function as a string or a function. Here we have used the argument compute and the _compute_line_weight is the name of the function used to calculate the line weight.
What is decorator in Odoo?
Decorators allow you to modify the way a method behaves. Moreover, it allows us to extend the behavior of another function, or in short, it takes in a function and adds certain functionality to it, and then returns the function.
How are computed fields used in data entities?
Computed field 1 Value is generated by an SQL view computed column. 2 During read, data is computed by SQL and is fetched directly from the view. 3 For writes, custom X++ code must parse the input value and then write the parsed values to the regular fields of the data entity. 4 Computed fields are used mostly for reads.
How are writes and name fields computed in Visual Studio?
For reads, the field combines the name and address of the customer into a nice format. For writes, your X++ code parses the combined value into its separate name and address values, and then the code updates the regular name and address fields. In Microsoft Visual Studio, right-click your project, and add the existing FMCustomerEntity.
Can a virtual field be computed as a computed column?
Yes – The field is synchronized as a SQL view computed column. Requires an X++ method to compute the SQL definition string for the column. The virtual column definition is static and is used when the entity is synchronized. After that, the X++ method is not called at run time.
Where are the computed fields stored in D365?
For writes, custom X++ code must parse the input value and then write the parsed values to the regular fields of the data entity. The values are stored in the regular fields of the data sources of the entity. Computed fields are used mostly for reads.
