What the data for this category looks like
The internal office and employee services data for railway operations mainly comes from ticket scheduling systems, crew scheduling systems, equipment inspection ledgers, and office approval databases. Data update cycles cover real-time scenarios such as ticket and inspection reports, daily updates such as schedule changes, and shift cycles such as crew attendance records. Most documents use structured fields, including employee ID, train number, inspection point ID, fault level, working hours and other fields. Some fields have dedicated units: train numbers use a combination of letters and numbers, working hours are measured in hours, and inspection points are sequence numbers without units.
What constraints these characteristics impose on forms and interactions
The high proportion of structured fields requires forms to support fixed options and dynamic dropdown linkage configuration. This prevents format errors caused by free text entry. Real-time updated ticket and inspection data requires forms to perform real-time validation of field legality during submission. It blocks submission requests that do not match the current operating status. Shift-updated schedule data requires forms to support interaction logic for filtering associated data by shift cycle. This ensures the data source called by employees matches the current working period. Multi-role collaborative office scenarios require form interaction permissions to be configured by position. Only fields that need to be filled in for the corresponding position are displayed.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Form input component | Bind corresponding structured data sources by field type | Matches the characteristics of multiple structured fields in railway operations |
| User selection component | Bind employee/train list filtered by position permissions | Ensures interaction permissions match the assigned position |
formInput validation rules | Configure format validation regular expressions for corresponding fields | Blocks inputs that do not comply with railway system specifications |
userSelect linkage logic | Link associated data sources based on main field values | Adapts to dynamic dropdown interaction requirements |
| Data loading timeout | 60 seconds | Adapts to the latency of internal railway office networks |
| Single load data count | Top 15 entries | Adapts to the scale of single-page data volume within railway internal systems |
| Form cache duration | 10 minutes | Prevents outdated data from affecting real-time interactions |
Three Common Mistakes
- Issue: The HTTP module configured in the workflow cannot correctly receive custom variables passed from the form. Cause: The output parameters of the form component are not one-to-one bound to the input parameter fields of the HTTP request.
- Issue: The search results associated with the form only cover a single type of business data, and cannot match the needs of multiple data sources. Cause: The linkage trigger logic for multiple knowledge bases is not configured, and only the retrieval rules for a single knowledge base are bound.
- Issue: A field format error is returned after the form is submitted. Cause: Format validation rules for the corresponding fields are not configured for
formInput, so inputs that do not comply with railway system specifications are not blocked properly.
How to Confirm the Configuration is Complete
- Enter the form editing page, switch the role permissions corresponding to the target position, and verify that only the fields that need to be filled in for that position are displayed.
- Fill in a test field that does not conform to the required format, trigger the validation logic, and verify that inputs that do not comply with railway system specifications are blocked.
- After configuring the
userSelectlinkage logic, modify the main field value, and verify that the associated data source is automatically updated. - Submit a test form, and verify that the HTTP module in the workflow can correctly receive the passed custom variables.
