Struct FieldAccess 

pub struct FieldAccess { /* private fields */ }

Who may view one field of a model’s records, and who may change it, which ResourceDef::field_access declares: every resource the panel mounts over the model obeys the rule.

A request the view rule refuses sees no column, filter, grouping, detail entry or relation column reading the field, no export column, and no control for it: an edit keeps the stored value, and a create takes the control’s default, else the blank answer. When the field has no default and the record form requires it, or its rules refuse a blank answer, as an accepted checkbox does, that request may not create. One the edit rule refuses sees the control disabled. Either answers 400 to a submission posting the field.

use tablo_core::FieldAccess;

FieldAccess::new().view(is_hr).edit(is_payroll);

Implementations

impl FieldAccess

pub fn new() -> Self

pub fn view(self, rule: impl Fn(&Cx) -> bool + Send + Sync + 'static) -> Self

Let only the requests rule allows view the field.

pub fn edit(self, rule: impl Fn(&Cx) -> bool + Send + Sync + 'static) -> Self

Let only the requests rule allows change the field, among the ones that view it.
