# RequestTemplate
|
|
|
|
A reusable template authored by a seller. When a buyer visits the template's `shareableLink`, the front-end pre-fills a new [[PurchaseRequest]] with the template's category, urgency, specs, delivery info, and an optional default seller `proposal`. The schema mirrors `PurchaseRequest` for fast cloning, plus template-specific bookkeeping (`isActive`, `usageCount`, `maxUsage`, `expiresAt`).

## Virtuals
|
|
|
|
None defined.
|
|
|
|
## Indexes
|
|
|
|
Defined at `backend/src/models/RequestTemplate.ts:283-293`:
|
|
|
|
- `{ categoryId: 1 }`
|
|
- `{ productType: 1 }`
|
|
- `{ isActive: 1 }`
|
|
- `{ createdAt: -1 }`
|
|
- `{ expiresAt: 1 }`
|
|
- `{ sellerId: 1, isActive: 1 }`
|
|
- `{ shareableLink: 1, isActive: 1 }`
|
|
- `{ productType: 1, isActive: 1 }`
|
|
- `{ categoryId: 1, productType: 1 }`
|
|
|
|
`shareableLink` and `sellerId` already get indexes from `unique: true` / field-level conventions (see source comment at line 282).

## Instance Methods

## Static Methods

None defined.
|
|
|
|
## Relationships
|
|
|
|
- **References**: [[User]] (`sellerId`), [[Category]] (`categoryId`).
|
|
- **Referenced by**: [[PurchaseRequest]] (`metadata.templateId` as string), [[Review]] (`subjectId` when `subjectType === 'template'`).

## State Transitions
|
|
|
|
```mermaid
|
|
stateDiagram-v2
|
|
[*] --> active : created
|
|
active --> inactive : seller toggles off
|
|
inactive --> active : seller toggles on
|
|
active --> expired : expiresAt passed
|
|
active --> capped : usageCount == maxUsage
|
|
expired --> [*]
|
|
capped --> [*]
|
|
```
|
|
|
|
> [!note] Soft state
|
|
> Only `isActive` is persisted directly. `expired` and `capped` are derived at query time using `expiresAt` and `usageCount`.
|
|
|
|
## Common Queries
|
|
|
|
```ts
|
|
// Seller's active templates
|
|
RequestTemplate.find({ sellerId, isActive: true }).sort({ createdAt: -1 });
|
|
|
|
// Public template by slug
|
|
RequestTemplate.findOne({ shareableLink: slug, isActive: true });
|
|
|
|
// Bump usage atomically
|
|
RequestTemplate.findOneAndUpdate(
|
|
{ _id, isActive: true, $or: [{ maxUsage: null }, { $expr: { $lt: ['$usageCount', '$maxUsage'] } }] },
|
|
{ $inc: { usageCount: 1 } },
|
|
{ new: true }
|
|
);
|
|
|
|
// Cleanup expired
|
|
RequestTemplate.find({ expiresAt: { $lt: new Date() }, isActive: true });
|
|
```
