What this category of data looks like
Data is primarily sourced from port operation management systems, container scheduling platforms, customs clearance databases, and customer appointment portals. Update frequencies cover three categories: real-time (shipping schedules, berth occupancy), daily (throughput, operation volume), and monthly (cargo type classification statistics). Most individual documents are structured tables, containing fields such as port code, port name, vessel name and voyage, cargo type, operation weight (tons), container TEU volume, customs clearance duration (hours), etc. Some documents also include time-series data for operation links.
What constraints these characteristics impose on the "forms and interactions" workflow
Real-time dynamic data updates require forms to support no-refresh loading, to avoid data invalidation caused by cache expiration. The structured multi-field feature requires forms to be configured with field validation rules, restricting weight and container volume to non-negative values, and matching port codes against a preset code library. Different cargo types correspond to differentiated field groups; the interaction must support dynamically displaying corresponding input items after cargo type selection, to reduce wasted form space. For bulk import scenarios, adaptation to CSV format exported from port systems is required, with validation of field completeness and format compliance to prevent invalid data imports.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | CSV/Excel files for bulk port imports often contain multiple batches of operation data, and single file volume usually does not exceed 500 MB |
FORM_FIELD_VALIDATE_TIMEOUT | 30 seconds | Port field validation involves code matching and value range verification; 30 seconds can cover complex validation logic |
DYNAMIC_FORM_SWITCH_DELAY | 200 milliseconds | Loading corresponding field groups when switching cargo types; a 200 millisecond delay ensures smooth interaction without lag |
BATCH_IMPORT_MAX_ROWS | 10000 rows | Single-batch port operation data volume is usually within 10,000 rows; this value balances import efficiency and system load |
SEARCH_INPUT_DEBOUNCE_MS | 500 milliseconds | Port code search requires matching against the code library; debounce settings reduce the number of invalid requests |
FORM_FIELD_REQUIRED_RULE | Configured per core business fields | Missing core business fields will prevent subsequent marketing content from accurately targeting target customers |
The parameter values provided on this page are all common recommended starting points for configuration. Actual values are affected by material format, 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: After adjusting the browser window size, all forms and loaded port data disappear. Cause: The
FORM_CACHE_PERSISTparameter is not configured, or the cache expiration time is set too short, causing the form state to fail to recover after window re-rendering. - Symptom: When bulk importing port data, some required fields are left unfilled but no validation prompt is received. Cause: The mandatory validation logic for
FORM_FIELD_REQUIRED_RULEis not enabled, or the validation rules do not cover core business fields such as vessel name and voyage. - Symptom: Unable to select bound port knowledge base variables in the JSON input box, and parameter parsing fails after submission. Cause: The
JSON_INPUT_SUPPORT_VARconfiguration is not enabled, or the variable filtering rules do not limit shipping port data sources.
How to confirm the configuration is correct
- Adjust the browser window size to verify whether forms and loaded port data display normally after re-rendering.
- Upload a test file matching the port data format to check whether field validation triggers corresponding prompts.
- Switch cargo type options to confirm whether the corresponding field groups can be dynamically loaded or hidden.
- Bind variables to the JSON input box to verify whether variable placeholders can be correctly identified and replaced.
