Struct Inline 

pub struct Inline {
    pub target_model: &'static str,
    pub fk_field: &'static str,
    pub label: Option<&'static str>,
    pub max_rows: usize,
    pub display_field: Option<&'static str>,
}

One related-children section to render below a parent model’s edit form. v1 surface: read-only listing of up to max_rows children matching <target.fk_field> = <parent.id>, each row a click-through to its own edit page, with an “Add new …” link that lands the operator on the child’s new form (the operator fills the parent FK manually for now).

Project authors declare these on the parent via ModelAdmin::inlines:

fn inlines() -> &'static [Inline] {
    &[Inline {
        target_model: "Appointment",
        fk_field: "patient_id",
        label: Some("Appointments"),
        max_rows: 50,
    }]
}

target_model must match a registered admin entry’s SINGULAR_NAME. fk_field is the column on the child that holds the parent’s id. A typo in either name silently renders an empty section.

Fields

target_model: &'static str

fk_field: &'static str

label: Option<&'static str>

Section title. None → fall back to the target model’s display_name.

max_rows: usize

Cap how many children are fetched + rendered. Operators who need to see the rest follow a “…and N more” link to the target’s list page pre-filtered to this parent.

display_field: Option<&'static str>

Column on the target whose value is rendered as each inline row’s clickable label. None falls through the framework’s display-field ladder (name → title → full_name → email) and finally to #<id>. Set this for child models without a natural-name column (e.g. Appointment.status or Loan.borrowed_at).
