What the data for this category looks like
Data sources for coal chemical industry yield and market trend data mainly include public market databases from domestic coal deep processing industry associations, official market interfaces from futures exchanges, and data interfaces from bulk commodity spot trading platforms. Data update rhythms fall into three categories: spot transaction data is updated after daily market close, futures trading data is pushed in real time during trading hours, and industry statistical data is updated weekly or monthly. A single standard data document includes the following fields: product code, product name, release time, benchmark price, daily transaction average price, weekly average price, monthly cumulative trading volume. The corresponding units are none, Chinese name, ISO 8601 format timestamp, yuan/ton, yuan/ton, yuan/ton, 10,000 tons respectively. No preset percentage fields are included in data documents, and all change values are presented as absolute numbers.
What constraints these characteristics impose on sharing and embedding
The coal chemical category covers multiple sub-varieties such as methanol, olefins, and urea, and data update frequencies vary greatly. The sharing and embedding link needs to adapt to multi-variety screening and high-frequency update requirements. High-frequency real-time futures data requires sharing links and embedded components to support scheduled refreshing, to avoid displaying outdated content. The multi-variety field structure requires sharing pages to support parameterized filtering; otherwise, full data will lead to a cluttered interface. Most practitioners in the coal chemical industry use Chinese terminology, so sharing interface language adaptation must match industry usage habits. Team scenarios need to support multiple business lines to create multiple sharing links, avoiding quantity restrictions that affect business operations. Multi-unit fields in data also require embedded configurations to support custom display units, to avoid unit confusion.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
anonymous_share_enabled | true | Coal chemical market data is available to industry practitioners, no mandatory login is required to view it. Enabling anonymous access lowers access barriers |
share_expire_hours | 24 hours | Coal chemical spot data is updated daily. Setting an expiration time of 24 hours ensures shared content always matches the latest daily market trends |
iframe_auto_refresh_interval | 3600 seconds | Balances data timeliness and server load, adapting to the daily update rhythm of spot market data |
share_filter_params | ["product_type", "publish_date"] | Filters irrelevant varieties and historical data, only displaying daily market trends for target coal chemical categories |
share_language | zh-CN | Matches usage habits of domestic industry practitioners, avoiding translation bias for coal chemical professional terminology |
max_anonymous_share_links_per_app | 100 | Adapts to sharing needs of multiple business lines in a team, adjusting the default quantity limit of 10 |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Issue: After a Docker-deployed instance restarts, previously created anonymous sharing links become inaccessible, and the console returns a
404 Not Foundstatus code. Cause: The storage directory for sharing links was not mounted to the host machine's persistent storage. Local stored link data is cleared after the container restarts. - Issue: The embedded iframe interface displays English terminology by default, and coal chemical professional names do not match industry-standard expressions. Cause: The
share_languageparameter was not configured. The system uses English as the default language, and no parameters adapted to the domestic industry were specified. - Issue: After creating more than 10 anonymous sharing links for a team edition application, new links fail to be created, and a quantity limit exceeded prompt pops up on the interface. Cause: The team-level
max_anonymous_share_links_per_appconfiguration item was not adjusted. The default limit is 10, and no expansion was performed based on business needs.
How to confirm configuration is complete
- Access created sharing links, check that displayed fields match configured
share_filter_params, confirm only daily market data for the target coal chemical category is shown. - Wait for the duration of the configured
iframe_auto_refresh_interval, then refresh the embedded page, confirm page data has updated to the latest release time. - Try to create more sharing links than the configured
max_anonymous_share_links_per_appquantity, confirm no limit exceeded prompt is triggered. - Manually modify the
langparameter of the sharing link toen, confirm interface text switches to English, verifying effectiveness of the language configuration.
