What the data for this category looks like
Data for this category originates from three main sources: officially authorized brand pricing systems, circulating market data from vertical second-hand jewelry trading platforms, and purchase records uploaded by users. Official guide prices are updated alongside new product launches every 1 to 3 months. Second-hand circulating market data is fully refreshed each early morning. User-provided data supports bulk import or single-item entry. The data document is a structured table with fields including jewelry SKU, material, labor cost, total purchase price, current circulating price, and number of holding days. Labor cost, total purchase price, and current circulating price use yuan as their unit. Holding days uses days as its unit. Yield rates are shown as relative coefficients, with no percentage markers.
What constraints these characteristics impose on form and interaction workflows
Multiple data sources require the form to support both automatic pull and manual entry interaction modes. Regular updates to official guide prices and second-hand market data require configuration of scheduled synchronization interfaces to avoid outdated data from static caching. Field validation must cover core items such as material, labor cost, and holding days: material must be limited to preset jewelry category options, labor cost and total purchase price must be restricted to non-negative values, and holding days must not be later than the current system date. Field linkage logic must be tied to yield rate calculation. When total purchase price or current circulating price is modified, the corresponding coefficient is automatically updated synchronously, eliminating the need for repeated user input. The SKU field must support fuzzy search matching to reduce the probability of manual input errors.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
form_field_required | Set SKU, total purchase price, and current circulating price as required, with all other fields optional | These three fields are core input items for yield rate calculation. Missing values will prevent valid results from being generated |
sync_interval_seconds | 86400 seconds (once daily) | Second-hand market data updates daily, and official guide prices update less frequently. Daily synchronization balances timeliness and resource consumption |
auto_calculate_trigger | Trigger in real time after field value changes | Jewelry yield rates must update dynamically with input data. Real-time triggering improves interaction smoothness |
search_match_threshold | 0.75 | Balances search accuracy and matching scope. Prevents missing valid SKUs from overly high thresholds, or introducing irrelevant results from overly low thresholds |
data_sync_timeout | 30 seconds | Jewelry data volume is small. 30 seconds covers most synchronization scenarios, and a retry mechanism can be triggered if a timeout occurs |
form_field_validation_rule | Labor cost, total purchase price, and current circulating price ≥ 0; holding days ≥ 1 | Prevents invalid negative costs or unreasonable holding durations |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material types, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test with your own samples before finalizing settings.
Three common mistakes
- Symptom: Calling the FastGPT form interface via an external platform returns a 400 status code with no form structure data. Cause: Form external exposure permission is not enabled in the application configuration, or API call signature verification rules are not configured correctly.
- Symptom: Yield rate calculation results are 0 or abnormal values after form submission. Cause: Numeric validation for
form_field_validation_ruleis not configured, resulting in users entering negative total purchase prices or 0 holding days. - Symptom: No matching results appear in the SKU search dropdown menu. Cause:
search_match_thresholdis set to an overly high value, making it impossible to match partial SKU keywords entered by users.
How to confirm configuration is complete
- Call the FastGPT form acquisition API, and check that the returned field list fully matches the pre-configured form fields.
- Manually modify any core input field in the form, and verify that the yield rate coefficient is automatically updated synchronously.
- Upload test data containing invalid values, and confirm that the corresponding validation error prompt is triggered.
- Wait for one synchronization interval cycle to end, and check that second-hand market data has completed automatic refresh and update.
