What this category of data looks like
Reference only; verify against the target FastGPT release and deployment documentation.
What constraints these characteristics impose on the "forms and interactions" link
Because data must match fixed formats and has high real-time update requirements, form interactions must enforce field format validation to prevent invalid data from entering the system. There are many bulk business processing scenarios, so forms must support bulk input or import, while limiting the volume of data submitted in a single operation to prevent system overload. Some fields such as SKU number and location code are core business identifiers, so they must be set as required fields and linked to backend data validation to avoid missing key information. Real-time updated data requires that associated data be refreshed synchronously after form submission to prevent data inconsistency.
How to configure the settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Form input node | formInput, enable image/file reception | Adapt to business input requirements such as warehouse documents and weighing photos |
| Form validation rules | Match formats by field type, e.g., validate "area-aisle-shelf-layer" format for location codes | Match fixed format requirements of warehouse logistics data, reduce invalid submissions |
| Default value binding | Bind to global variables, value range is 1–1000 digits | Match fixed warehouse identifiers for warehouse logistics, reduce repeated input |
| Bulk input limit | Top 500 entries | Adapt to reasonable data volume for single business processing, avoid system overload |
| Input timeout threshold | 30 seconds | Match response requirements of real-time operations, prevent work interruptions caused by long waits |
| Single input character limit | 800–1200 characters | Adapt to conventional content length of business documents, avoid input overflow |
Three common mistakes
- Scenario: An "input format not supported" error is returned when submitting a logistics document image in base64 format. Cause: The image type input reception configuration was not enabled in the
formInputnode. - Scenario: After setting the form default value to a global variable, the actually submitted field is empty. Cause: The sync binding switch for global variables and form default values was not enabled in FastGPT v4.17.0.
- Scenario: When processing inbound and outbound operations in bulk, only some entries are processed after submitting more than 100 entries at a time. Cause: The bulk input limit configuration parameter was not adjusted, and the default value restricts the volume of data submitted in a single operation.
How to confirm the configuration is correct
- Fill in a test location code, check if a format error prompt pops up. Validation passes if the code follows the "area-aisle-shelf-layer" rule.
- Set the default value to a global variable, refresh the form to check if the default value is correctly loaded as the preset warehouse identifier.
- Upload a test document image in base64 format, confirm that the form can be submitted normally without errors.
- Bulk import 150 test SKU data entries, confirm that all entries are received and processed by the system.
