What This Category of Data Looks Like
Grain reserve-related data comes from inventory ledgers, quality inspection reports, and rotation plan documents from reserve depots at all levels, plus officially released grain reserve management regulations. Daily inventory ledgers are updated each day. Rotation plans are released 1 to 3 months in advance. Quality inspection reports are generated synchronously with each inbound batch. Document structure falls into two categories: structured ledger tables and unstructured attachments. Structured fields include grain reserve variety, storage quantity (unit: ton), depot name, inbound batch, and quality grade. Unstructured attachments include inbound receipts and scanned quality inspection reports.
Constraints Imposed on Forms and Interactions by These Characteristics
Fixed properties of structured fields require forms to be configured with precise input validation. For example, quantity fields must be positive values with the ton unit to prevent invalid data entry. The hierarchical storage data structure requires forms to support cascading selection. First select a depot, then the corresponding grain variety and inbound batch to narrow the search scope. Unstructured attachments require forms to integrate file upload components that support common document and image formats. Frequently updated ledger data requires form queries to directly link to the latest data in real time, and local caching must be disabled to ensure inquiries match current inventory status. Multi-level business classification also requires forms to support progressive questioning, dynamically loading subsequent optional content based on prior selections.
How to Configure Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
formInput validation rules | Only allow positive values plus the ton unit; text fields limited to 1000 characters or fewer | The unit for grain reserve quantity fields is tons, and invalid input must be avoided; inquiry content should not be excessively long |
userSelect cascading logic | Cascading linkage by depot → grain variety → inbound batch | Grain reserve data is stored hierarchically by depot, variety, and batch; cascading selection narrows the search scope |
| File upload configuration | Support JPG/PNG/PDF formats; maximum single file size 200 MB | Common formats and sizes for quality inspection reports and inbound receipts fall within this range |
| Single submission data volume limit | 10 records | The submission scale of single-batch grain reserve ledgers typically does not exceed this number |
| Timeout period | 300 seconds | Average time for cross-depot data queries falls within this range, calibrated via actual testing with FastGPT v4.17.0 |
| Field required settings | Depot, grain variety, and quantity are required fields | Core information for service inquiries cannot be missing, ensuring work orders can be processed effectively |
Three Common Configuration Mistakes
- Phenomenon: Core fields are empty after form submission, and work orders cannot be processed normally. Cause: Required validation rules for
formInputare not configured, allowing required core fields to be omitted during submission. - Phenomenon: Knowledge base search results include grain reserve data from unrelated depots, and the scope cannot be limited to the specified folder. Cause: Folder permission binding configuration for
userSelectis not enabled, so the search scope is not restricted to the corresponding business folder. - Phenomenon: Uploading quality inspection reports is blocked by the system, and attachments cannot be submitted. Cause: File upload format and size limits are not configured, causing attachments that meet business requirements to be rejected due to format or size exceeding thresholds.
How to Confirm Proper Configuration
- Fill in the required form fields, then verify that all core information is fully displayed on the work order details page after submission.
- Select a depot, then a grain variety in sequence, and check that the drop-down menu only displays optional content for the corresponding level.
- Upload a scanned quality inspection report that meets the format requirements, then confirm that it can be submitted normally and displays an attachment preview in the work order.
- Trigger a preset data analysis operation, then check that the associated grain reserve data of the current work order is automatically called.
