有两个日期框架,一个是df1,另一个是df2,如下所示:
DF1:
a b id
2010-01-01 1 4 21
2010-01-01 2 5 22
2010-01-01 3 6 23
2010-01-01 4 7 24
2010-01-02 1 4 21
2010-01-02 2 5 22
2010-01-02 3 6 23
2010-01-02 4 7 24
2010-01-03 1 4 21
2010-01-03 2 5 22
2010-01-03 3 6 23
2010-01-03 4 7 24
...........................
DF2:
c d id
2010-01-02 1 4 21
2010-01-02 2 5 22
2010-01-02 3 6 23
2010-01-02 4 7 24
2010-01-03 1 4 21
2010-01-03 2 5 22
2010-01-03 3 6 23
2010-01-03 4 7 24
...........................
我想通过公共索引合并或加入两个数据帧(请注意df1中的某些索引不在df2中)和id,我希望加入的数据帧如下所示
c d a b id
2010-01-02 1 4 1 4 21
2010-01-02 2 5 2 5 22
2010-01-02 3 6 3 6 23
2010-01-02 4 7 4 7 24
2010-01-03 1 4 1 4 21
2010-01-03 2 5 2 5 22
2010-01-03 3 6 3 6 23
2010-01-03 4 7 4 7 24
我使用了以下代码
df = df1.join(df2, on = ['id'], how='inner')
但这不起作用
答案 0 :(得分:3)
IIUC:
module.exports = function (callback) {
var request = require("request");
var getResponse = null;
request.get({
url: '/Home/testReport',
json: true,
}, function (error, response, body) {
if (!error && response.statusCode == 200)
getResponse = body;
});
var jsreport = require('jsreport-core')();
jsreport.init().then(function () {
return jsreport.render({
template: {
content: 'template bla bla bla',
engine: 'jsrender',
recipe: 'phantom-pdf'
},
data: getResponse
}).then(function (resp) {
callback(/* error */ null, resp.content.toJSON().data);
});
}).catch(function (e) {
callback(/* error */ e, null);
});
