What the data for this category looks like
Core data for consumer building materials comes from offline store sales ledgers, online official mall product detail pages, supply chain delivery lists, and user lead capture forms. Full category information is updated in bulk when new products launch. Daily restocks and price adjustments are updated weekly or on demand. Each data entry’s document structure includes category, specific model, specification parameters (such as tile laying size, pipe wall thickness), material, unit (square meters, meters, kilograms, sets), inventory status, and applicable renovation scenarios. Different subcategories have notable differences in core fields, with no unified mandatory standards.
Constraints Imposed on Forms and Interactions
The multi-dimensional segmented fields for consumer building materials require forms to support cascading linkage. Forms dynamically load corresponding sub-fields based on the user’s selected primary category, reducing invalid options. Obvious field differences across subcategories require forms to support switching field configurations, to meet collection needs for different subcategories including tiles, pipes, and coatings. The variety of units requires forms to have built-in unit verification and automatic conversion rules, preventing users from entering incorrect values. Bulk product document imports require forms to support pre-format verification, avoiding misalignment of core fields such as specifications and materials. The real-time nature of inventory data requires forms to pull the latest inventory status when loading, providing users with accurate restocking prompts.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxFormFields | 20–30 | Consumer building materials marketing forms need to cover core fields such as category, specifications, materials, applicable scenarios, and contact information. Excessive fields will reduce completion rates |
formFieldCascadeDepth | 3 levels | The hierarchical classification of consumer building materials usually follows primary category → secondary subcategory → specific specification. Three levels are sufficient to cover common segmented needs |
UPLOAD_FILE_MAX_SIZE | 500 MB | Files such as building material CAD drawings and product manuals usually fall within the 100-300 MB range. This upper limit covers most upload scenarios |
formSubmitTimeout | 30 seconds | Form submission requires synchronous inventory verification and generation of customized marketing materials. 30 seconds is sufficient for conventional request durations |
fieldUnitAutoConvert | Enabled | Consumer building materials use multiple units (square meters, meters, kilograms). Automatic conversion reduces user input errors |
recallThreshold | 0.75–0.85 | Knowledge base content matching user building material needs must be recalled. A threshold that is too low will introduce irrelevant results, while a threshold that is too high will miss matching items |
The parameter values provided on this page are conventional recommendations used as a starting point 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 one’s own samples before finalizing settings.
Three Common Errors
- Phenomenon: Forms return a
400 Bad Requestafter submission, with the prompt "Missing required fields". Cause: Unique consumer building material fields such as specifications and applicable scenarios are not marked as required, leading to the omission of core information during user submission. - Phenomenon: The AI interaction flow cannot automatically switch marketing content based on building material parameters entered by users. Cause: Conditional branch rules based on form fields are not configured, making it impossible to bind GPT output results to building material parameters submitted by users.
- Phenomenon: After bulk uploading building material product documents, form field matching fails and a large number of null values appear. Cause: A reasonable upper limit for
UPLOAD_FILE_MAX_SIZEis not set, leading to interruption of large file uploads and incomplete parsed fields.
How to Confirm Proper Configuration
- Fill in the required fields and optional segmented fields of the form, then check after submission whether the returned results include all filled parameters.
- Upload a small building material product document, and check whether the parsed fields correctly cover core information such as category, specifications, and units.
- Test the linkage logic of cascading fields, confirm whether the corresponding secondary classification options are automatically loaded after selecting a primary building material category.
- Call the API interface for form submission, check whether the request parameters match the field rules configured in the backend.
