What the Data for This Category Looks Like
Data primarily comes from domestic futures exchanges, spot trader public quotation platforms, and industry association public reports. Update frequencies are divided into real-time (same-day spot quotations), trading day updates (futures market prices), and weekly or monthly (industry inventory and supply and demand reports). Most documents are structured CSV or Excel formats, with fields including product name, specification/model, origin, transaction price, inventory balance, and delivery cycle. Units are uniformly physical measurement units such as yuan/ton, ton, etc. There are no complex nested formats, but the number of fields is large and some fields are optional.
Constraints on Forms and Interactions
The multi-field and optional field properties of industrial metal data require forms to support conditional field display. Load exclusive options such as specifications and origins based on the selected metal variety to avoid format errors caused by free text input. The need to batch upload structured documents requires interactive components to support automatic parsing of CSV and Excel files. Automatically match the system's preset industrial metal field mapping rules to reduce manual configuration costs. The real-time and high-frequency update characteristics of data require that marketing content such as quotations and inventory embedded in forms support scheduled refresh. Submitted lead data must also be associated with the latest category parameters to ensure the timeliness of marketing information. The multi-unit measurement feature requires the form to automatically recognize and uniformly display units to prevent user confusion over different measurement methods.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | The file size of single Excel/CSV files for quotations and inventory in the industrial metal industry is usually manageable. 1000 MB covers most scenarios |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing industrial metal documents with multiple fields and categories requires a long processing time. 600 seconds prevents mid-parsing timeouts |
form_field_condition_switch | Enabled | The specification and origin fields vary across different industrial metal varieties. Conditional display simplifies the form filling process |
auto_field_mapping | Enabled | The industrial metal industry has universal field naming rules. Automatic mapping reduces the workload of manual configuration |
content_refresh_interval | 300 seconds | Spot quotation data is updated at a high frequency. A 300-second refresh interval balances timeliness and system resource usage |
UPLOAD_JSON_MAX_CHAR | 80000 characters | JSON format files for industrial metal batch data usually do not exceed this length, covering most marketing data statistics needs |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Phenomenon: Structured industrial metal data uploaded via forms is not included in the large model's statistical analysis, and conversation results do not include the content of the uploaded file. Cause: The
auto_field_mappingconfiguration is not enabled. The system cannot automatically extract valid fields from the uploaded file, resulting in data not being correctly parsed and loaded. - Phenomenon: When submitting a form via API, the parameters in the request body cannot correctly match the industrial metal form fields. Form fields are empty after submission. Cause: The relevant interface parameters are not configured according to the universal field naming rules of the industrial metal industry. The parameter names do not correspond to the preset form fields, resulting in data mapping failure.
- Phenomenon: A
408 Request Timeouterror occurs when parsing large industrial metal inventory files. Cause: ThePARSE_FILE_TIMEOUT_SECONDSconfiguration value is lower than the actual parsing required time, causing the system to terminate the request before parsing is complete.
How to Verify Successful Configuration
- Upload a structured file that conforms to the industry standard format of industrial metals, and verify whether the system automatically recognizes and loads valid fields without manual adjustment of mapping rules.
- Switch to select different industrial metal varieties, and verify whether the form only displays exclusive fields for the corresponding variety and hides irrelevant options.
- Wait for the configured refresh interval, and check whether the quotation and inventory data in the embedded marketing materials have been updated.
- Use the test environment to submit an API request, and verify that the parameters in the request body can be correctly synchronized to the form leads without field loss.
