如何使用python代码中的单个操作生成和下载两个报告。

def print_reports(self, cr, uid, ids, context):
    'I have to do it here'
    ...
    return {
        'type': 'ir.actions.report.xml',
        'report_name': 'certificate_of_origin',
        'datas': datas,
    }

我只需点击一下即可打印两个版本的certificate_of_origin，但我每次只能打印一个版本。

为此，您需要处理js代码。

在表单视图中添加以下代码：

<button string="Reports_print" name="print_reports" type="object"/>

然后我们需要使用python代码从js生成请求的报告，而不使用：

return {
        'type': 'ir.actions.report.xml',
        'report_name': 'my_report',
        'datas': datas,
        'nodestroy': True
    }

为此你的方法`print_reports＆＃39;应该是：

def print_reports(self, cr, uid, ids, context):
    """DO NOT EDIT !"""

需要从js代码中捕获按钮点击事件。

在你的js脚本中 /modulename/static/js/script.js 执行此操作：

openerp.MODULENAME=function(instance)
{

    var QWEB=instance.web.qweb,_t=instance.web._t;
    instance.web.DataSet.include({
        call_button:function(method, args){
            var id = args[0];
            if(String(method)=='print_reports'){
                //get_reports should be created in modele_name class
                new instance.web.Model('modele_name',this.get_context()).ca    ll('get_reports',[id],{context:this.get_context()}).done(function(reports){
                    for(var b=0; b<reports.length; b+=2)
                          download('data:application/pdf;base64,'+reports[b],reports[b+1]+'.pdf','application/pdf');
                    });
            }
            return this._super(method, args);
        }
    });
};

我们从get_reports调用python方法js，结果报告为64 base string
get_reports方法在发送之前生成并格式化报告他们到js 做到如下：

def get_reports(self, cr, uid, ids, context):
    #Get datas used in the reports from modele

    datas = {
        'ids': ids,
        'model': 'modele_name',
        'form': {
            'key': value,
             ...
        }
    }
    pdf1 = self.pool.get('ir.actions.report.xml').render_report(cr,
                                                                uid,
                                                                ids,
                                                                "report_name1",
                                                                datas,
                                                                context=None)


    pdf2 = self.pool.get('ir.actions.report.xml').render_report(cr,
                                                                uid,
                                                                ids,
                                                                "report_name2",
                                                                datas,
                                                                context=None)
    ...

    #We send 'report naem ' to name downloaded report ('reports[b+1]+'.pdf')
    return pdf1[0].encode('base64'), 'report_name1', pdf2[0].encode(
        'base64'), 'report_name2',...

值可以在RML代码中使用，如下所示：datas [＆＃39; form＆＃39;] [key] 。

要下载它们，我使用了download.js脚本，有很多方法可以做到这一点，但我发现download.js是最简单的方法 download.js的内容：

//download.js v3.0, by dandavis; 2008-2014. [CCBY2] see     http://danml.com/download.html for tests/usage
// v1 landed a FF+Chrome compat way of downloading strings to     local un-named files, upgraded to use a hidden frame and     optional mime
// v2 added named files via a[download], msSaveBlob, IE (10+)     support, and window.URL support for larger+faster saves     than dataURLs
// v3 added dataURL and Blob Input, bind-toggle arity, and     legacy dataURL fallback was improved with force-download mime and     base64 support

// data can be a string, Blob, File, or dataURL




function download(data, strFileName, strMimeType) {
    var self = window, // this script is only for browsers     anyway...
        u = "application/octet-stream", // this default mime     also triggers iframe downloads
        m = strMimeType || u, 
        x = data,
        D = document,
        a = D.createElement("a"),
        z = function(a){return String(a);},


        B = self.Blob || self.MozBlob || self.WebKitBlob || z,
        BB = self.MSBlobBuilder || self.WebKitBlobBuilder ||     self.BlobBuilder,
        fn = strFileName || "download",
        blob, 
        b,
        ua,
        fr;

    //if(typeof B.bind === 'function' ){ B=B.bind(self); }

    if(String(this)==="true"){ //reverse arguments, allowing     download.bind(true, "text/xml", "export.xml") to act as a callback
        x=[x, m];
        m=x[0];
        x=x[1]; 
    }



    //go ahead and download dataURLs right away
    if(String(x).match(/^data\:[\w+\-]+\/[\w+\-]+[,;]/)){
        return navigator.msSaveBlob ?  // IE10 can't do a[download], only Blobs:
            navigator.msSaveBlob(d2b(x), fn) : 
            saver(x) ; // everyone else can save dataURLs un-processed
    }//end if dataURL passed?

    try{

        blob = x instanceof B ? 
            x : 
            new B([x], {type: m}) ;
    }catch(y){
        if(BB){
            b = new BB();
            b.append([x]);
            blob = b.getBlob(m); // the blob
        }

    }



    function d2b(u) {
        var p= u.split(/[:;,]/),
        t= p[1],
        dec= p[2] == "base64" ? atob : decodeURIComponent,
        bin= dec(p.pop()),
        mx= bin.length,
        i= 0,
        uia= new Uint8Array(mx);

        for(i;i<mx;++i) uia[i]= bin.charCodeAt(i);

        return new B([uia], {type: t});
     }

    function saver(url, winMode){


        if ('download' in a) { //html5 A[download]          
            a.href = url;
            a.setAttribute("download", fn);
            a.innerHTML = "downloading...";
            D.body.appendChild(a);
            setTimeout(function() {
            a.click();
            D.body.removeChild(a);
            if(winMode===true){setTimeout(function(){     self.URL.revokeObjectURL(a.href);}, 250 );}
            }, 66);
            return true;
        }

        //do iframe dataURL download (old ch+FF):
        var f = D.createElement("iframe");
        D.body.appendChild(f);
        if(!winMode){ // force a mime that will download:
            url="data:"+url.replace(/^data:([\w\/\-\+]+)/, u);
        }


        f.src = url;
        setTimeout(function(){ D.body.removeChild(f); }, 333);

    }//end saver 


    if (navigator.msSaveBlob) { // IE10+ : (has Blob, but not     a[download] or URL)
        return navigator.msSaveBlob(blob, fn);
    }   

    if(self.URL){ // simple fast and modern way using Blob and     URL:
        saver(self.URL.createObjectURL(blob), true);
    }else{
        // handle non-Blob()+non-URL browsers:
        if(typeof blob === "string" || blob.constructor===z ){
            try{
                return saver( "data:" +  m   + ";base64,"  +      self.btoa(blob)  ); 
            }catch(y){
                return saver( "data:" +  m   + "," +     encodeURIComponent(blob)  ); 
            }
        }

        // Blob but not URL:
        fr=new FileReader();
        fr.onload=function(e){
            saver(this.result); 
        };
        fr.readAsDataURL(blob);
    }   
    return true;
} /* end download() */

为了能够在脚本中调用download方法，您必须加载download.js文件，以便修改MODULENAME_view.xml以添加新行

<?xml version="1.0" encoding="utf-8"?>
<openerp>
    <data>
        <template id="assets_backend_MODULENAME" name="MODULENAME assets" inherit_id="web.assets_backend">
            <xpath expr="." position="inside">
                ...
                <!-- The new line-->
                <script type="text/javascript" src="/MODULENAME/static/src/js/download.js"></script>
                ...
            </xpath>
        </template>
    </data>
</openerp>

Answer 2

我不认为使用当前报道可能。 2年前我使用jasper报告做了同样的事情。并使用子报告功能。

在Odoo8中打印两份报告
