# Pricelists
|
|
|
|
## Types
|
|
|
|
PriceForge supports three pricelist types (`source` field):
|
|
|
|
| Type | Data source | Status |
|
|
|------|-------------|--------|
|
|
| `estimate` | `qt_lot_metadata` — snapshot of current prices | Active |
|
|
| `warehouse` | `stock_log` — stock import data | Active |
|
|
| `competitor` | B2B marketplace APIs | Reserved |
|
|
|
|
---
|
|
|
|
## Estimate
|
|
|
|
**Source**: snapshot of current component prices from `qt_lot_metadata`.
|
|
|
|
**Filter**:
|
|
- Include only rows with `current_price > 0`.
|
|
- Exclude hidden rows (`is_hidden = 1`).
|
|
|
|
**Stores**:
|
|
- `price_period_days` — price calculation window
|
|
- `price_coefficient` — markup coefficient
|
|
- `manual_price` — manually set price
|
|
- `meta_prices` — historical prices
|
|
|
|
**Purpose**: primary pricelist for calculations and estimates.
|
|
|
|
**Categories**: loaded from `lot.lot_category` for each component.
|
|
|
|

|
|
|
|
## Warehouse
|
|
|
|
**Source**: `stock_log` (stock import records).
|
|
|
|
**Rules (CRITICAL)**:
|
|
|
|
1. **Only mapped partnumbers** — only positions with a record in `lot_partnumbers` are included. Unmapped partnumbers must not appear in any form.
|
|
2. **No pricing settings** — do not load from `lot_metadata`: no `price_period_days`, `price_coefficient`, `manual_price`, `meta_prices`.
|
|
3. **Price method**: always `weighted_avg` (quantity-weighted average).
|
|
4. Field `price_method` always contains `"weighted_avg"`.
|
|
5. These are raw stock prices without additional processing.
|
|
|
|
**Categories**: loaded from `lot.lot_category`.
|
|
|
|
**Implementation**: `internal/warehouse/snapshot.go`
|

|
## Competitor
|
|
|
|
Reserved for future integration with B2B marketplace APIs (automated quotes).
|
|
|

|
|
|
|
## Data Model
|
|
|
|
```go
|
|
type Pricelist struct {
|
|
ID uint `gorm:"primaryKey"`
|
|
Version string
|
|
Source string // "estimate" | "warehouse" | "competitor"
|
|
// ...
|
|
}
|
|
|
|
type PricelistItem struct {
|
|
ID uint `gorm:"primaryKey"`
|
|
PricelistID uint
|
|
LotName string `gorm:"size:255"`
|
|
Price float64 `gorm:"type:decimal(12,2)"`
|
|
LotCategory *string `gorm:"column:lot_category;size:50" json:"category,omitempty"`
|
|
|
|
// Virtual fields (via JOIN or programmatically)
|
|
LotDescription string `gorm:"-:migration" json:"lot_description,omitempty"`
|
|
AvailableQty *float64 `gorm:"-" json:"available_qty,omitempty"`
|
|
Partnumbers []string `gorm:"-" json:"partnumbers,omitempty"`
|
|
}
|
|
```
|
|
|
|
> `gorm:"-:migration"` — no DB column created, but mapped on SELECT.
|
|
> `gorm:"-"` — fully ignored in all DB operations.
|
|
|

|
|
|
|
## Categories (lot_category)
|
|
|
|
- **Source**: `lot.lot_category` column in table `lot`.
|
|
- **NOT** from `qt_lot_metadata`.
|
|
- **NOT** derived from LOT name.
|
|
- Persisted into `qt_pricelist_items.lot_category` when pricelist is created.
|
|
- JSON field name: `"category"`.
|
|
- JOIN with `lot` is only needed for `lot_description`; category is already in `qt_pricelist_items`.
|
|
- Default value when category is missing: `PART_`.
|
|

|
## Pricelist Creation (background task)
|
|
|
|
Creation runs via Task Manager. Handler returns `task_id`; frontend polls.
|
|
|
|
```
|
|
POST /api/pricelists/create
|
|
→ { "task_id": "uuid" }
|
|
→ polling GET /api/tasks/:id
|
|
→ { "status": "completed", "result": { "pricelist_id": 42 } }
|
|
```
|
|
|
|
Task type: `TaskTypePricelistCreate`.
|
|
|
|
**Implementation**:
|
|
- Service: `internal/services/pricelist/service.go`
|
|
- Warehouse calc: `internal/warehouse/snapshot.go`
|
|
- Handler: `internal/handlers/pricelist.go`
