What data for this category looks like
Data related to infrastructure construction project yields comes primarily from financial institution infrastructure project financial management accounting systems, engineering supervision progress confirmation documents, and local housing and urban-rural development department infrastructure project filing databases. Two update cadences apply: regular projects are updated monthly, while key demonstration projects are updated weekly. Documents use a structured table format, including fields such as project unique code, project name, construction category, current period completed investment, current period settlement revenue, cumulative completed investment, cumulative settlement revenue, and total project investment. Investment-related fields use CNY yuan as the unit, engineering quantity fields use units such as cubic meters, linear meters, and kilometers, and revenue-related fields use CNY yuan as the unit.
What constraints these characteristics impose on the "forms and interactions" workflow
The multi-source, cross-system nature of infrastructure project yield data requires forms to support external API binding and batch import functions. It also requires configuration of field validity check rules to prevent mismatched data formats across systems. The parallel monthly and weekly update cadence requires forms to support custom sync cycle configuration, with two interaction options: scheduled trigger and manual trigger, to meet the update needs of different projects. The structured multi-field document structure requires forms to use grouped layout, displaying project basic information, current period data, and cumulative data in separate columns to reduce entry errors. The diverse unit types require forms to include a built-in unit automatic conversion component that automatically converts between yuan and ten thousand yuan, reducing interaction costs.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
external_data_sync_interval | 86400 seconds (weekly projects) or 2592000 seconds (monthly projects) | Matches the weekly/monthly update cadence of infrastructure projects, avoids excessive sync frequency consuming server resources |
batch_import_max_rows | 500 records per batch | Adapts to the conventional scale of single-batch ledger data for infrastructure projects, balances upload efficiency and server load |
field_unit_auto_convert | Enabled | Covers multiple unit types in infrastructure data including CNY yuan, ten thousand yuan, cubic meters, etc., reduces manual conversion errors |
form_field_validation_rules | Pre-set field validation templates | Targets the multi-field characteristics of structured data, quickly filters invalid entry content |
external_api_auth_config | API Key authentication | Adapts to the authentication methods of most infrastructure data providers, supports cross-system data pulling |
form_layout_mode | Columned grouped layout | Displays project basic information, current period data, and cumulative data by category, improves interaction readability |
The parameter values provided on this page are 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. It is recommended to test on deployment-specific samples before finalizing settings.
Three common mistakes
- Phenomenon: When configuring an external data source API, calling the API returns empty results after entering the authentication key. Cause: Authentication parameters and form fields are not correctly bound, or the key's permissions do not cover the infrastructure data pulling scope.
- Phenomenon: When calling the knowledge base at the yield reporting node, the interface prompts "No knowledge base selected". Cause: The knowledge base corresponding to the infrastructure project is not bound during the form interaction stage, or the knowledge base permissions are not opened for the current application.
- Phenomenon: When calling visual data in the code running node, the first search result of the knowledge base cannot be obtained. Cause: The knowledge base recall rule is not configured during the form interaction stage, or the recall result is not bound to the input variable of the code node.
How to confirm configurations are complete
- Manually trigger an external data sync, check if the infrastructure data in the form matches the data source, and adjust the sync interval to match the actual update cadence of the project.
- Perform a batch import of a single test ledger, check if field units are automatically converted, and if entered data complies with pre-set validation rules.
- Bind the corresponding knowledge base, call the knowledge base in test interactions, and confirm that the "No knowledge base selected" error prompt no longer appears.
- Check the variable binding of the code node, confirm that the knowledge base recall result has been correctly mapped to the corresponding input parameter.
