Portal rules
A portal rule is a named condition. It gives a set of M-Files property-based conditions a name, and that name can then be used anywhere a component asks when something should happen.
That indirection is the whole idea: the condition is written once and referred to by a name that says what it means, rather than being repeated on every component that needs it.
How a rule is used
Section titled “How a rule is used”Most components have a Show when field deciding whether the component appears. It defaults
to true, so the component is always shown; setting it to false hides it permanently, which
is not useful on its own.
It becomes useful with a rule. Define one called has_project_manager whose condition is
'Project manager' is not empty, then set a component’s ShowWhen to has_project_manager.
The component now appears only on objects that have a project manager.
The same names work in Required when and Additional when, which is how one rule can govern whether a field appears, whether it is on the metadata card, and whether it has to be filled in.
Combining rules
Section titled “Combining rules”Rules combine with boolean operators:
and, or, not and equals, with parentheses for precedence.
Example
Section titled “Example”Given two more rules:
created_by_me— the object the portal is showing was originally created by the current user.deleted_by_me— that object was deleted by the current user.
A segment that should appear only on objects the current user both created and deleted takes
deleted_by_me and created_by_me in its ShowWhen field.


Settings
Name
The name of the rule. This should be unique and descriptive.
