What This Category’s Data Looks Like
Energy metals data primarily comes from public industry association reports, futures exchange market data, customs import and export statistics, and information disclosed by mining enterprises. Update cycles are divided into multiple tiers: spot prices are updated each trading day, monthly supply and demand data is released in the middle and late days of each month, and quarterly inventory data is made public 1 to 2 weeks after the quarter ends. Document structures are mostly structured tables and PDF reports, containing fields such as grade proportion, inventory volume, transaction prices, and more. Common units include tons, yuan per ton, and percentage. Some overseas data uses pounds and US dollars per ounce as units.
What Constraints These Characteristics Impose on Forms and Interactions
The multi-dimensional structured data characteristics of energy metals require forms to support multi-field linkage matching. For example, selecting a specific category such as lithium or cobalt automatically loads the corresponding unit options and core fields. Frequently updated data requires forms to integrate real-time data pulling interfaces to avoid displaying outdated supply and demand or price information. Fields with multiple coexisting units need unit conversion controls configured to adapt to unit differences between domestic and overseas markets, reducing user input errors. Scenarios where structured and unstructured documents coexist require the form upload module to support parsing rules for different formats, while distinguishing data field types to avoid parsing confusion. In marketing customer acquisition scenarios, forms need to preset industry common fields to reduce user input costs.
How to Set Configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Energy metals industry reports are mostly PDF or Excel files, with a single file usually not exceeding 300 MB. Setting a reasonable upper limit avoids exceeding limits |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Structured table parsing requires matching multiple fields, while unstructured reports require full-text retrieval. The timeout setting must cover the complete parsing process |
FORM_FIELD_AUTO_UNIT | Enabled | Multiple units such as tons, pounds, yuan per ton, and US dollars per ounce exist for energy metals. Automatic conversion reduces user input errors |
DYNAMIC_SELECT_OPTIONS | Bind to industry data interface | Energy metal category and regional parameters change dynamically with the market. Dynamic loading ensures the timeliness of options |
FORM_FIELD_VALIDATION_RULE | Preset field verification based on category | Core fields differ across energy metal categories. For example, lithium ore requires verification of grade range, while ferronickel requires verification of carbon content parameters |
UPLOAD_FILE_ALLOW_EXT | pdf, xlsx, csv | Industry common data formats include PDF reports, Excel supply and demand tables, and CSV market data, covering mainstream usage scenarios |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: The file upload button is not displayed in the chat scenario input box. Cause: The
CHAT_INPUT_UPLOAD_ENABLEconfiguration item is not enabled, and the allowed upload file format whitelist is not configured. - Symptom: The options in the user selection module do not update dynamically with market data. Cause: Static hardcoded option lists are still used, and no industry data interface is bound to implement dynamic loading.
- Symptom: No image parsing results are obtained after calling an external script via HTTP request. Cause: No upload file parameter transfer rules are configured in the workflow, causing the images uploaded by the form to not be correctly passed to the target script interface.
How to Confirm the Configuration Is Complete
- Enter the form editing interface, check whether the unit conversion related configuration items are enabled, select different energy metal categories to verify whether the field units automatically match.
- Upload a file that conforms to the industry format, confirm that the upload module has no error messages, and that the parsed result fields match the actual file content.
- Trigger the loading process of the user selection module, verify that the options are obtained from the bound data source, and do not use static hardcoded content.
- Test the trigger action of the corresponding function, confirm that the returned results meet business expectations.
