What the data for this category looks like
Data for this category comes from three main sources: official manufacturer public quotation systems, authorized distributor API interfaces, and industry spot trading matching platforms. There are three update schedules:
- Official manufacturer guide prices are synchronized and updated daily
- Spot trading quotes refresh every 15 minutes
- Inventory levels are synchronized daily
Each data entry includes the complete component model, package specification, current transaction unit price, 7-day average price, number of suppliers, minimum order quantity, and delivery lead time. Unit price uses yuan per piece as the unit. Delivery lead time uses working days as the unit. Minimum order quantity uses pieces as the unit. Data fields are adjusted based on component category segmentation. Optional fields differ between passive and active components.
What constraints these characteristics impose on form and interaction workflows
Multiple data sources with differing update schedules restrict the form to support switching configurations for multi-source data pulling. A single fixed data source cannot be used. Different data has unique update frequencies, so the interaction link must offer optional modes for manual triggering and scheduled refresh. Short-interval refresh is supported for spot data. Official manufacturer guide prices only support daily refresh. Field differences exist across component categories, so the form must support dynamic loading of corresponding fields. It automatically displays optional configuration items based on the selected component category to avoid interference from redundant fields. Some fields are bound to fixed units, so the form must add unit verification rules to prevent input of non-standard unit values. Multi-source data field mapping requires precise matching, so the interaction link must include mapping preview and verification functions to avoid field misalignment.
How to Set Configurations
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
multi_source_data_enable | Enabled | Adapt to the data acquisition needs of multiple data sources including electronic component manufacturers, distributors, and spot trading platforms |
auto_refresh_interval | 900 seconds | Match the 15-minute update schedule of spot trading quotes, balancing data timeliness and API call frequency |
dynamic_field_config | Match by category | Adapt to field differences across different electronic component categories, with distinct optional fields for passive and active components |
field_unit_validation | Enabled | Bind fixed units such as yuan per piece, working days, and pieces, and verify the legality of input formats |
data_field_mapping | Preset standard mapping | Match the standard field structure of electronic component data to avoid field misalignment across multi-source data |
input_max_length | 120 characters | Adapt to the standard naming length of official component models, preventing parsing errors caused by overly long inputs |
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 Mistakes
- Symptom: The form's refresh interval options only provide fixed gears, and custom interval values cannot be selected. Cause:
auto_refresh_intervalis configured in enumeration mode, and custom input permission is not enabled, which prevents some users from selecting intermediate range parameters. - Symptom: When calling the data pulling tool, only partial electronic component field content is returned, and complete data cannot be obtained. Cause: The complete mapping rules for
data_field_mappingare not configured, and multi-source data fields have not undergone precise matching. - Symptom: A field unit verification failure error appears after form submission. Cause: Custom verification rules are not configured for the special trade units of electronic components. For example, some traders use "K" as the unit for thousand pieces, and no corresponding parsing logic is added.
How to Confirm the Configuration Is Complete
- Open the form configuration page, check if
multi_source_data_enableis enabled, and confirm all required data source interfaces have been added. - Select different categories of electronic components to load the form, confirm dynamic fields automatically adjust displayed content based on the selection.
- Enter a non-standard unit value, check if the form triggers the corresponding verification prompt, and confirm the unit verification rule is active.
- Wait for the configured automatic refresh interval, confirm the form automatically updates data without requiring manual refresh.
