What the data for this category looks like
This category’s data originates from engineering quality and safety supervision systems, construction site real-name management platforms, supervision logs, and test reports. Updates occur weekly. Daily documents include supervision plans, supervision inspection records, hidden danger rectification notices, quality problem handling forms, and completion acceptance supervision reports. Fields cover supervision subjects, inspection items, rectification requirements, acceptance conclusions, and more. Some fields link to identifiers such as project numbers and construction sections. No unified fixed units of measurement apply.
Constraints imposed on the deployment and upgrade link
Configure multi-source data docking logic during deployment to ensure documents from different channels can be accessed uniformly, as this category’s data sources are scattered and involve multiple supervision systems and on-site platforms. Set up incremental synchronization scripts after deployment to meet the weekly update frequency requirement. Retain synchronization links during upgrades to avoid data gaps. Preload document parsing components adapted to different formats during deployment to ensure all document types can be read correctly, as daily document types include diverse administrative and test files. Configure field mapping rules during deployment to associate corresponding project context during Q&A workflows, since data is linked to project identifiers.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
MONGODB_URI | mongodb://<admin account>:<password>@<database address>:<port>/fastgpt?authSource=admin | Stores structured documents such as supervision inspection records and hidden danger rectification notices, adapts to storage needs for weekly incremental synchronization |
REDIS_URL | redis://:<cache password>@<cache address>:<port>/0 | Caches Q&A context and synchronization task status, reduces repeated query frequency |
STORAGE_S3_ENDPOINT | Local object storage address or compliant cloud storage service endpoint | Stores large-volume unstructured documents such as supervision logs and test reports, supports files up to 500–1000 MB |
FILE_TOKEN_KEY | 32-bit randomly generated encrypted string | Encrypts access credentials for file uploads, prevents unauthorized access to project-related documents |
DB_MAX_LINK | 20–30 concurrent connections | Adapts to concurrent connection counts for weekly batch data synchronization, avoids exhausting database connections |
FE_DOMAIN | https://<deployment domain>:<port> | Configures the frontend access entry, ensures internal supervision personnel can access the Q&A system normally |
Three Common Mistakes
- Phenomenon: After enabling the file upload function, an error occurs when parsing the document address, returning "file does not exist" or "insufficient permissions". Cause:
FILE_TOKEN_KEYis not configured to generate valid access credentials, orSTORAGE_S3_ENDPOINTis not pointed to the correct document storage path. - Phenomenon: External platforms calling the chat interface experience response timeouts that exceed business expectations. Cause:
REDIS_URLis not configured to cache context, orDB_MAX_LINKis set too low, leading to exhausted database connections and inability to process concurrent requests in a timely manner. - Phenomenon: Dependency installation errors occur during local compilation and deployment, or a 500 error is returned when testing the interface with curl after Docker deployment. Cause: The dependency versions specified in FastGPT v4.17.0 are not used, or
MONGODB_URIis not correctly configured to establish a connection with the database.
How to Confirm the Configuration Is Complete
- Run a database connection test to confirm that the
MONGODB_URIandREDIS_URLconfigurations can establish normal connections. - Upload a supervision inspection record document to verify that the file upload and parsing process completes normally, and confirm that the
STORAGE_S3_ENDPOINTandFILE_TOKEN_KEYconfigurations are valid. - Call the external chat interface to verify that the response speed meets business requirements, and confirm that the
DB_MAX_LINKand cache configurations adapt to concurrent needs. - View the incremental synchronization task logs to confirm that the weekly data synchronization process can be triggered and executed normally.
