Struct ModelFormSet 

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

A formset for managing multiple model instances

Implementations

impl<T: FormModel> ModelFormSet<T>

pub fn new( prefix: String, instances: Vec<T>, config: ModelFormSetConfig, ) -> Self

Create a new ModelFormSet with instances

Examples

use reinhardt_forms::{ModelFormSet, ModelFormSetConfig};

let config = ModelFormSetConfig::new();
let instances = vec![]; // Empty list of model instances
let formset = ModelFormSet::<MyModel>::new("formset".to_string(), instances, config);
assert_eq!(formset.prefix(), "formset");

pub fn empty(prefix: String, config: ModelFormSetConfig) -> Self

Create an empty ModelFormSet (for creating new instances)

Examples

use reinhardt_forms::{ModelFormSet, ModelFormSetConfig};

let config = ModelFormSetConfig::new().with_extra(3);
let formset = ModelFormSet::<MyModel>::empty("formset".to_string(), config);
assert_eq!(formset.total_form_count(), 3);

pub fn prefix(&self) -> &str

pub fn instances(&self) -> Vec<&T>

pub fn form_count(&self) -> usize

pub fn total_form_count(&self) -> usize

pub fn is_valid(&mut self) -> bool

Validate all forms in the formset

Examples

use reinhardt_forms::{ModelFormSet, ModelFormSetConfig};

let config = ModelFormSetConfig::new();
let mut formset = ModelFormSet::<MyModel>::empty("formset".to_string(), config);
let is_valid = formset.is_valid();

pub fn errors(&self) -> Vec<String>

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

Save all valid forms to the database

Examples

use reinhardt_forms::{ModelFormSet, ModelFormSetConfig};

let config = ModelFormSetConfig::new();
let mut formset = ModelFormSet::<MyModel>::empty("formset".to_string(), config);
let result = formset.save();

pub fn management_form_data(&self) -> HashMap<String, String>

Get management form data for HTML rendering

Examples

use reinhardt_forms::{ModelFormSet, ModelFormSetConfig};

let config = ModelFormSetConfig::new().with_extra(2);
let formset = ModelFormSet::<MyModel>::empty("article".to_string(), config);
let mgmt_data = formset.management_form_data();

assert!(mgmt_data.contains_key("article-TOTAL_FORMS"));
assert_eq!(mgmt_data.get("article-TOTAL_FORMS"), Some(&"2".to_string()));
