What This Category of Data Looks Like
This category of data typically comes from ERP systems, supplier delivery notes, logistics tracking information, and equipment manufacturer backends. Associated daily documents include purchase orders, delivery acceptance receipts, serial number lists, and invoice materials. Data updates are performed per individual project order or via weekly batch synchronization. Core fields include equipment model, serial number, delivery time, supplier information, and acceptance status. Data flows only around the delivery milestones of a single integrated project, with no unified global statistical standard.
Constraints Imposed by These Characteristics During Deployment and Upgrade
Data sources for this category are scattered and bound to specific project milestones. During deployment, connection parameters for multiple data sources must be configured to adapt to the interface formats of different systems. Data update frequency is per individual entry or weekly batch, so the knowledge base incremental update strategy must support small-batch, low-latency synchronization to avoid resource consumption from full re-imports. The uniqueness requirement for core fields such as serial numbers requires configuring document deduplication rules during deployment to prevent asset account inconsistencies caused by duplicate entries. Additionally, because this system serves specific integrated projects, deployment must support project-level permission isolation to ensure that delivery data for different projects does not interfere with each other.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
MONGODB_URI | mongodb://fastgpt:yourpassword@db-host:27017/fastgpt?authSource=admin | Purchase orders and serial number lists for this category are multi-field document-style data, which adapts to MongoDB's storage structure and supports flexible querying of project-level data |
REDIS_URL | redis://:redispass@redis-host:6379/0 | Caches session information for internal tickets and sharded indexes of delivery documents, adapting to high-frequency operations duty query requirements |
DB_MAX_LINK | 300 seconds | Data update frequency for this category is per individual entry or weekly batch. Long connections reduce reconnection overhead and avoid connection timeouts during high-frequency queries |
FE_DOMAIN | https://fastgpt.your-company-intranet.com | Configures the internal access domain name for ticket push during operations duty and callback requests for application management, adapting to internal collaboration scenarios for integrated projects |
STORAGE_S3_ENDPOINT | Determined via actual testing | Stores document attachments such as invoice materials and delivery acceptance receipts, adapting to access requirements for different cloud environments or on-premises storage |
Three Common Misconfigurations
- Symptom: A network error is prompted when deleting a self-built application. Cause:
FE_DOMAINand the backend API's cross-origin whitelist are not correctly configured, preventing front-end requests from being initiated normally. - Symptom: An error of Cannot read properties of undefined is reported when calling the document parsing module. Cause: The
FILE_TOKEN_KEYconfiguration value was not updated synchronously after upgrading to FastGPT v4.17.0, resulting in failed document authentication. - Symptom: The number of serial number query results does not match. Cause: The timeout setting for
DB_MAX_LINKwas not adjusted, causing connections to be disconnected during high-frequency queries and returning incomplete query results.
How to Confirm Proper Configuration
- Access the configured
FE_DOMAINand confirm normal login and access to the application management page. - Upload a purchase order document and confirm that core fields such as equipment model and serial number can be properly parsed and extracted.
- Initiate an internal operations duty ticket and confirm normal submission and push to preset duty personnel.
- Log in to the Redis instance and confirm that cached index records for delivery documents exist.
