What the data for this category looks like
Data related to decoration and renovation yield rates and market trends is primarily sourced from local housing and urban-rural development departments' renovation cost indexes, supplier quotation ledgers, and project settlement data from construction enterprises. Data updates follow a layered schedule: daily market data for core building materials, weekly unit cost data for bulk building materials, bi-weekly construction labor quotations, and daily aggregated yield rate reports for individual projects. Standard fields for structured documents include project_identifier, decoration_category, construction_stage, main_material_unit_cost, labor_unit_cost, overhead_expense, project_total_cost, daily_return. All cost-related fields use the unit yuan per square meter of renovated area, and the daily_return field uses the unit yuan per square meter of renovated area.
What Constraints These Characteristics Impose on Forms and Interactions
The layered data updates and daily report broadcast requirements for the decoration and renovation industry require forms to support scheduled import configuration for multiple data sources, and to distinguish refresh cycles for different data to align with daily report generation schedules. Differences in data formats across sources require forms to support multiple structured file formats such as CSV and XLSX, to prevent daily report data import failures due to format mismatches. The layered attributes of fields and unified unit requirements necessitate setting staged input modules in forms, with default unit prompts to reduce input errors during data entry. Differences in cost weights across decoration categories require forms to support dynamic field loading after category switching, ensuring only required fields for the current category are displayed to improve daily report filling efficiency. Logical correlations between data require forms to include basic validation rules, preventing invalid inputs where the sum of individual cost items exceeds total project cost, and ensuring the accuracy of daily report data.
How to Configure Settings
| Configuration Item | Recommended Value | Rationale for This Value |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 500 MB | Decoration and renovation yield rate data includes files such as building material quotation ledgers and project settlement sheets, which typically have large individual file sizes, so sufficient upload space must be reserved. |
ALLOWED_FILE_EXTENSIONS | csv, xlsx, json | Cost data for the decoration and renovation industry is mostly stored in structured table formats. Supporting common office spreadsheet and data exchange formats covers most import scenarios. |
PARSE_HTTP_TIMEOUT | 120 seconds | When calling external scripts to parse on-site project material photos, the scripts must complete image transcoding, OCR recognition, and data mapping. The timeout setting must match the process duration. |
DYNAMIC_FORM_TRIGGER_CONDITION | Triggered after selecting the decoration_category field | Decoration categories include home renovation, commercial renovation, etc. Different categories correspond to different cost field weights, so corresponding form modules must be dynamically loaded after category selection. |
INPUT_VALIDATION_RULE | Total project cost field must be greater than the sum of main material cost, labor cost, and overhead expenses | Prevents entry of unreasonable cost data, and ensures the accuracy of basic data for yield rate calculations. |
HTTP_REQUEST_RETRY_TIMES | 2 times | Network fluctuations may cause request failures when calling external script interfaces. Limited retries can improve the success rate of data imports. |
The parameter values provided on this page are all conventional recommendations, used as starting points for configuration. Actual values are affected by material types, 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: The options for the
decoration_categoryfield in the form cannot be updated with external data sources. Cause: TheDYNAMIC_FORM_TRIGGER_CONDITIONparameter is not configured, or the interface address of the external classification data source is not bound, resulting in the option pool failing to synchronize the latest decoration category information. - Symptom: HTTP requests calling external scripts return a
408 Request Timeouterror. Cause: ThePARSE_HTTP_TIMEOUTparameter is set too short, and the time taken by the script to complete image base64 encoding and OCR parsing exceeds the configured timeout threshold. - Symptom: The yield rate calculation result is empty after form submission. Cause: The validation logic for the
INPUT_VALIDATION_RULEparameter is not enabled, and the entered cost data has logical conflicts. The system does not intercept invalid inputs, causing the calculation to interrupt.
How to Confirm the Configuration Is Complete
- Upload a structured file of building material quotations for decoration and renovation, confirm that the file can be successfully parsed and matched to the corresponding form fields.
- Select a decoration category option in the form, confirm that the associated cost fields dynamically adjust their display status based on the selection.
- Enter a set of logically conflicting cost data, confirm that the form triggers the corresponding input validation prompt.
- Trigger an HTTP request to call an external script, confirm that the request completes a response within a timeframe matching the actual execution duration of the script.
