What This Category of Data Looks Like
Data for urban investment platform declaration materials and file review primarily comes from internal project declaration ledgers, special bond approval files, land transfer filing documents, and daily operation and maintenance archives. Data is updated in real time as projects progress, with special bond declaration batches updated quarterly. Single documents have a multi-page mixed structure, including project proposals, fund calculation sheets, land use certificates and other attachments. Fields include project ID, special bond quota (unit: ten thousand yuan), land area (unit: square meters), repayment period (unit: years), approval document number, and more. Some files contain mixed scanned documents and structured tables.
What Constraints Do These Characteristics Impose During Deployment and Upgrade
This category of data includes multi-page mixed documents, structured fields, and scanned materials. Deployment must adapt to multimodal parsing capabilities to avoid losing scanned content when only text parsing is supported. Quarterly batch updates create peak bulk import loads, so sufficient vector database storage space and concurrent processing quotas must be reserved during deployment. Specific field unit requirements require structured data field mapping rules to be configured during deployment to prevent unit recognition errors. During upgrades, vector indexes of historical files must be retained to avoid resource consumption from reprocessing existing data.
Configuration Settings
| Config Item | Recommended Value | Rationale |
|---|---|---|
DB_MAX_LINK | 1000–1500 seconds | Adapt to the loading requirement of multiple associated materials in a single file for urban investment platforms, avoid single request timeout |
MONGODB_URI | mongodb://localhost:27017/fastgpt | Store declaration material metadata and vector indexes, comply with FastGPT official deployment standards |
REDIS_URL | redis://:custom password@localhost:6379/0 | Cache bulk import batch data, reduce repeated database query pressure, adapt to load characteristics of quarterly concentrated updates |
STORAGE_S3_ENDPOINT | http://192.168.1.100:9000 | Store scanned files and attachments, adapt to storage requirements of multimodal documents |
FE_DOMAIN | http://internal-oa.chengtou.com:3000 | Configure frontend access domain name, used to generate preview links for declaration materials, match internal office system jump rules |
Three Common Misconfigurations
- Phenomenon: A network connection failure error appears when running the
docker build -f ./projects/command after local deployment. Cause: No network proxy is configured inside the container, making it impossible to pull base images required by project dependencies, which adapts to deployment scenarios of internal isolated networks for urban investment platforms. - Phenomenon: Scanned copies of historical declaration files fail to load properly after upgrading to FastGPT v4.17.0. Cause: The original
FILE_TOKEN_KEYconfiguration was not retained during the upgrade, preventing verification of storage medium access permissions. - Phenomenon: The system times out and interrupts during bulk import of quarterly special bond declaration materials. Cause: The
DB_MAX_LINKvalue was not adjusted, and the number of associated materials loaded in a single request exceeds the default threshold, leading to request timeout.
How to Verify Proper Configuration
- Run the
docker pscommand, confirm all FastGPT-related containers are in a running state, and check if container port mappings match internal office network access rules. - Upload a single-page structured declaration material, check if the parsed fields include preset fields such as project ID and special bond quota, confirming that structured parsing rules are active.
- Initiate a bulk import test, import 10 simulated files, check the vector database index generation progress, confirming that the storage configuration can write data normally.
- Access the frontend address configured in
FE_DOMAIN, attempt to generate a preview link for a declaration material, and confirm the link can normally jump to the corresponding document.
