Struct Field 

pub struct Field { /* private fields */ }

A single parsed column definition.

Implementations

impl Field

pub fn parse(spec: &str) -> Result<Self>

Parse one name:type[:modifier...] spec. Type defaults to string.

pub fn parse_all(specs: &[&str]) -> Result<Vec<Field>>

Parse every spec in specs, short-circuiting on the first error.

pub fn column_name(&self) -> String

The database column name. References get an _id suffix.

pub fn is_required(&self) -> bool

Whether the column (and therefore the model field) is NOT NULL. References are always non-null (the builder enforces it).

pub fn wants_index(&self) -> bool

Whether this field requested its own index.

pub fn params_struct_field(&self) -> String

Render a field for the scaffold’s form-params struct, e.g. pub title: String, — mirrors the column’s nullability.

pub fn active_model_set(&self) -> String

Render an ActiveModel struct-literal entry from a parsed form, e.g. title: Set(form.title), (used by create).

pub fn active_model_assign(&self) -> String

Render an ActiveModel field assignment from a parsed form, e.g. record.title = Set(form.title); (used by update).

pub fn html_input_type(&self) -> &'static str

The HTML <input type="…"> (or textarea/checkbox) for this column, used by the scaffold form view.

pub fn migration_line(&self) -> String

Render the migration builder line, e.g. t.string("title").not_null();. references passes the bare name (it appends _id itself).

pub fn alter_add_line(&self) -> String

Render an alter_table add-column line, e.g. t.add_column("email", |c| { c.string().not_null(); });. References become a NOT NULL <name>_id big integer.

pub fn alter_drop_line(&self) -> String

Render an alter_table drop-column line, e.g. t.drop_column("email");.

pub fn model_field(&self) -> String

Render the SeaORM model struct field, e.g. pub title: String, or pub age: Option<i32>, for a nullable column.

pub fn sample_form_value(&self) -> Option<&'static str>

A sample form value for this column, used to build request bodies in the generated scaffold controller test. None for types that cannot be represented as a urlencoded scalar (binary), which are omitted.

pub fn sample_form_pair(&self) -> Option<String>

col=value pair for a urlencoded request body, or None to omit.

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Field

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
