pub struct ModelFormSet<T: FormModel> { /* private fields */ }

ModelFormSet for managing multiple model instances

This is similar to the base FormSet but specifically designed for model instances.

Implementations

impl<T: FormModel> ModelFormSet<T>

pub fn new(prefix: String) -> Self

Create a new ModelFormSet

Examples

let formset = ModelFormSet::<User>::new("user".to_string());

pub fn with_extra(self, extra: usize) -> Self

Set extra forms count

pub fn with_can_delete(self, can_delete: bool) -> Self

Enable deletion

pub fn with_can_order(self, can_order: bool) -> Self

Enable ordering

pub fn with_max_num(self, max_num: Option<usize>) -> Self

Set maximum number of forms

pub fn with_min_num(self, min_num: usize) -> Self

Set minimum number of forms

pub fn add_form(&mut self, form: ModelForm<T>) -> Result<(), String>

Add a model form to the formset.

Returns an error if adding the form would exceed max_num.

pub fn forms(&self) -> &[ModelForm<T>]

Get all forms

pub fn forms_mut(&mut self) -> &mut Vec<ModelForm<T>>

Get mutable access to forms

pub fn is_valid(&mut self) -> bool

Validate all forms in the formset

pub fn errors(&self) -> &[String]

Get validation errors

pub fn save(&mut self) -> Result<(), FormError>

Save all forms in the formset

pub fn prefix(&self) -> &str

Get the formset prefix
