What the data for this category looks like
Data for this category comes primarily from the Ministry of Agriculture and Rural Affairs Feed Industry Monitoring System, ERP synchronized data from leading domestic feed enterprises, and third-party industry quotation platforms. There are two update schedules: bulk raw material feeds receive a full update at 8 AM daily, while niche custom feed categories receive incremental synchronization every 6 hours. Data is provided in structured table format, with five core fields per entry: feed variety, raw material purchase cost (yuan/ton), processing allocated cost (yuan/ton), ex-factory guide price (yuan/ton), unit profit amount (yuan/ton), and statistical date. No extra redundant statistical items are included.
What constraints these characteristics impose on the form and interaction workflow
The differing update schedules for this category’s data require forms to support filtering displayed content by data update time. Interfaces must also label the last update time of individual data entries to avoid generating reports with outdated data. All fields are numerical types with attached units. Forms must be configured with strict non-negative numerical validation to block non-numeric and negative input. The multi-data-source nature of the data requires forms to provide a dropdown option for data source switching, allowing users to select different industry monitoring platforms or internal enterprise data as the calculation basis. Additionally, because data fields are fixed, form submission items must correspond one-to-one with standard data fields to prevent synchronization failures caused by field mismatches.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Structured data files for the feed industry typically do not exceed 200 MB, so this sets reasonable buffer space |
UPLOAD_FILE_ALLOWED_EXTENSIONS | ["csv", "xlsx", "xls"] | CSV and Excel tables are commonly used formats for feed industry yield rate data |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Parsing large feed data files usually takes 60-90 seconds, so setting 120 seconds avoids timeout errors |
FORM_FIELD_VALIDATION_RULE | Only allow positive numerical values and standard field names | Feed data fields are all positive numerical values with units, so illegal input and mismatched fields must be blocked |
STREAM_RESPONSE_ENABLED | Enabled | Real-time display of calculation progress is required for yield rate broadcasts to improve interaction smoothness |
WORKFLOW_PLUGIN_INPUT_SCHEMA | Correspond one-to-one with standard feed data fields | Ensure plugin input matches standard data formats to avoid synchronization failures |
The parameter values provided on this page are all common recommended starting points 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 configuration errors
- Issue: After enabling the file upload component in a workflow, calling the document parsing tool returns a
413 Request Entity Too Largeerror. Cause: TheUPLOAD_FILE_MAX_SIZEparameter was not adjusted, and the default value is too small to allow large feed data files to be uploaded. - Issue: After adding a custom feed data parsing plugin, the workflow task does not display input and output parameters, and no error logs are generated. Cause:
WORKFLOW_PLUGIN_INPUT_SCHEMAand output fields were not correctly declared in the plugin configuration, so the platform cannot recognize the parameter structure. - Issue: A field empty error occurs after form submission, and the generated yield rate report has missing data. Cause: The form validation rules do not strictly restrict required fields, or input items do not match standard data fields.
How to confirm the configuration is complete
- Upload a standard feed data file, check whether the upload progress and parsing results meet expectations, and confirm that the file size and format comply with configuration requirements.
- Enter the workflow plugin configuration page, check whether the input and output parameters correspond one-to-one with standard feed data fields, and confirm that the plugin declaration is correct.
- Initiate a yield rate broadcast request, check whether calculation results are returned incrementally via streaming mode, and confirm that the streaming response configuration is active.
- Submit invalid numerical values such as negative numbers or non-numeric characters to the form, check whether corresponding validation blocking is triggered, and confirm that the form validation rules are effective.
