[英]How to dynamically generate schema for cube.js?
我一直在從事一個項目來生成可配置的儀表板。 所以我必須根據 api 請求動態生成模式。 有沒有辦法做到這一點?
如果有任何工作示例,這將非常有幫助!
這個場景有一個asyncModule
函數。 您可以查看以下示例:
const fetch = require('node-fetch');
const Funnels = require('Funnels');
asyncModule(async () => {
const funnels = await (await fetch('http://your-api-endpoint/funnels')).json();
class Funnel {
constructor({ title, steps }) {
this.title = title;
this.steps = steps;
}
get transformedSteps() {
return Object.keys(this.steps).map((key, index) => {
const value = this.steps[key];
let where = null
if (value[0] === PAGE_VIEW_EVENT) {
if (value.length === 1) {
where = `event = '${value[0]}'`
} else {
where = `event = '${value[0]}' AND page_title = '${value[1]}'`
}
} else {
where = `event = 'se' AND se_category = '${value[0]}' AND se_action = '${value[1]}'`
}
return {
name: key,
eventsView: {
sql: () => `select * from (${eventsSQl}) WHERE ${where}`
},
timeToConvert: index > 0 ? '30 day' : null
}
});
}
get config() {
return {
userId: {
sql: () => `user_id`
},
time: {
sql: () => `time`
},
steps: this.transformedSteps
}
}
}
funnels.forEach((funnel) => {
const funnelObject = new Funnel(funnel);
cube(funnelObject.title, {
extends: Funnels.eventFunnel(funnelObject.config),
preAggregations: {
main: {
type: `originalSql`,
}
}
});
});
})
