What the Data for This Category Looks Like
Data for this category originates from customer manuscripts, color management systems, press operation logs, ink and substrate batch records, spectrometers, barcode detectors and other equipment and systems. Daily business documents include pre-press files, imposition sheets, printing process sheets, ink color matching records, first article approval samples, barcode test results, and die-cutting and lamination logs. Data is updated for each order, batch and plate change. It includes fields such as plate number, color parameters, substrate model, barcode number and die-cutting accuracy. Document formats adjust dynamically based on order needs, with no universal fixed format.
Constraints Imposed by These Characteristics on Deployment and Upgrade
Data sources are scattered and update frequently. During deployment, configure systems to adapt to multi-source data access and support integration with external systems such as color management systems and press data interfaces. Document formats are not fixed and change per order. During deployment, set up flexible document parsing rules to support multiple business document types including pre-press files and imposition sheets. Each plate change triggers a data update. During upgrades, ensure real-time data synchronization to prevent expired ink batches or die-cutting parameters from being used in bid documents. Bid documents require review of text images, plate numbers, color values and barcode information. During deployment, configure dedicated verification logic for packaging structure, color matching and barcode readability to ensure output documents meet bid requirements.
Configuration Settings
This configuration guide is based on FastGPT v4.17.0.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
MONGODB_URI | mongodb://username:password@host:port/dbname?authSource=admin | Stores multiple types of business documents including pre-press files and imposition sheets, requires a stable document database connection |
REDIS_URL | redis://:password@host:port/0 | Caches real-time updated ink batch and barcode test data to reduce repeated read pressure |
STORAGE_S3_ENDPOINT | Access address of the enterprise internal object storage service | Stores large-volume business files such as first article approval samples and spectrometer test results |
DB_MAX_LINK | 20–30 | Adapts to parallel bid document generation requests for multiple orders, prevents database connection exhaustion |
FE_DOMAIN | Access domain name of the enterprise internal office system or official website | Binds the front-end page access address to ensure normal bid document preview and sharing links |
FILE_TOKEN_KEY | Randomly generated 32-bit string | Encrypts document access tokens to prevent unauthorized access to customer manuscripts and process documents |
Three Common Configuration Errors
- Model loading fails in the page configuration file, and the interface prompts that the model was not found. The cause is that
MONGODB_URIorREDIS_URLwas not correctly configured during deployment, causing model configuration information to fail to load normally. - The SaaS version frequently times out during access, and the interface returns a 504 status code. The cause is that
DB_MAX_LINKwas not adjusted based on order concurrency, causing the database connection pool to be exhausted and requests to fail to respond in a timely manner. - A 500 error is returned when importing printing process sheet documents. The cause is that
STORAGE_S3_ENDPOINTwas not configured or storage permissions are insufficient, making it impossible to read or write temporary files required for document parsing.
How to Verify Successful Configuration
- Access the front-end address bound to
FE_DOMAIN, and check if the page loads normally and displays the bid document generation entry. - Upload a test pre-press file, and check if the file can be parsed and stored normally with no error returned.
- Call the internal interface to query test data cached by
REDIS_URL, and confirm that the cache read and write links are normal. - Use
ROOT_KEYto generate a temporary token, verify that the encryption logic ofFILE_TOKEN_KEYtakes effect, with no unauthorized access occurring.
