What the data for this category looks like
Data sources for livestock and poultry farming yield rates include feeding ledgers of breeding entities, slaughter weight records, feed purchase vouchers, and raw material market data published by industry associations. There are two update rhythms for data: daily feeding consumption and raw material purchase data are updated per calendar day; core operational data such as slaughter volume and inventory volume are updated weekly. Each individual data document is a structured table, containing fields including pen number, inventory headcount, feed purchase unit price, average slaughter weight, unit breeding cost, and others. The corresponding units are head, kilogram, yuan per kilogram, and yuan per head, respectively.
Constraints on form and interaction from these data characteristics
Data sources with different update rhythms require forms to support switching data import time ranges by day or week. This prevents mixing expired or unsynchronized information. Fixed fields and units require forms to include built-in unit verification rules. This stops users from entering values that violate business specifications, such as incorrectly entering feed unit price as yuan per ton. Support batch import for structured documents from multiple sources. Provide preset field matching logic to avoid data misalignment caused by users adjusting table structures independently. Slaughter data has strong timeliness. Automatically verify data update time when forms are submitted. This ensures only slaughter records from the past 7 days are imported.
Configuration settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 200 MB | Structured ledger files for livestock and poultry farming are mostly single-page or multi-page tables. A single file usually does not exceed 200 MB. Exceeding this threshold triggers upload timeout. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Ledger files with multiple pens and multiple batches of data require traversing rows and columns for parsing. 600 seconds covers most single-file parsing scenarios. |
form_field_matching_mode | strict | Livestock and poultry farming data fields have fixed business meanings. Strict matching mode avoids calculation errors caused by field misalignment. |
batch_upload_max_count | 10 | Weekly batch imports of ledger files usually do not exceed 10 files. This value balances import efficiency and system load. |
input_unit_validate_enabled | enabled | Livestock and poultry farming data has clear unit requirements. Enabling verification reduces unit errors in user input. |
form_template_download_enabled | enabled | Providing standardized form templates reduces the cost of adapting to structured data import for users. It improves import success rates. |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three common errors
- Phenomenon: After batch importing livestock and poultry farming ledgers, fields such as pen number and feed unit price display as empty. Cause: The standardized form template provided by the platform was not used. Field order was adjusted or non-preset fields were added independently, causing the system to fail to match corresponding data.
- Phenomenon: After uploading a livestock and poultry farming ledger file, the system prompts "Parsing timed out" and returns error code
ERR_PARSE_TIMEOUT. Cause: The setPARSE_FILE_TIMEOUT_SECONDSvalue is less than 600 seconds. The number of rows in a single ledger file exceeds 1000, making parsing time exceed the preset threshold. - Phenomenon: When opening the form import interface, the display shows "Document input function is not yet available" and returns error code
ERR_FORM_DISABLED. Cause: The deployed version is 4.9.10alpha, and the form import function switch is not enabled. The corresponding configuration item must be manually enabled.
How to confirm configuration is complete
- Upload a pre-organized livestock and poultry farming ledger template file. Check whether the system automatically matches preset fields such as pen number and feed purchase unit price, and correctly fills data into corresponding form positions.
- Enter a value that does not meet unit requirements, such as filling "5 yuan per ton" as the feed unit price. Check whether the unit verification prompt is triggered.
- Upload 10 formatted ledger files. Check whether batch parsing and import can be completed normally.
- View the configuration value of
PARSE_FILE_TIMEOUT_SECONDS. Confirm that it is greater than the estimated parsing time of a single file.
