Hi,

We have the requierment, that a delivery note report has to have a copy with a watermark. The same report twice in a single pdf document. If possible the second iteration with a watermark.

To duplicate the report I use a simple script with pdf-utils:

const jsreport = require('jsreport-proxy')

async function afterRender(req, res) {
    res.content = await jsreport.pdfUtils.append(res.content, res.content);
}

Can I add a watermark within this script?
Maybe:

• use pdfUtils.parse to manipulate content of the second iteration directly
• or use pdfUtils with merge with another watermark template

What would be te best way to solve such a task?

Reto E.

I got it working.

The correct syntax is:

<span>{{../$pdf.pages.[0].items.[0]}}</span>

But the funny thing is, the assignment of a value does not always work. The pdfAddPageItem above does not work. But if I put it a few lines later after a $localizedResource it works:

{{$localizedResource.invoce}}{{{pdfAddPageItem invoiceid}}}

Do you have a fixed position for the hdr class? This would have the effect, that it repeats on that fixed position on every page.

Hi,

I have a invoice template and I want to pass the invoice-id to the header to print it on every page. And I can pass the value with handlebars like this to pdf-utils:

<span>{{invoiceid}}</span>{{{pdfAddPageItem invoiceid}}}

But I don't understand how to access this value on the header template?
It should be accessible like $pdf.pages[x].items[y]. What stands x and y for?

I tried 0 and 0 because it is on page 1 and it is the first (and only) item I add with pdfAddPageItem. So I added this to the header template:

{{$pdf.pages[0].item[0]}}

But I think I'm getting something wrong here...
Should be a rather simple task, I geuss.

Reto E.

Can I overwrite the language of a report with beforeRender, or is it mandatory to do it with the api call?

req.data has already the localized values ready for the report, the only way would be to overwrite those with the values from $resource 'manually'. Is this a correct and recommended procedure?

Like:

req.data.$localizedResource = req['data']['$resource']['en-shipping'];

Perfect. Thx.

We get data with beforeRender from a webservice and save this to req.data:

req.data = JSON.parse(response);

But as soon as we manipulate req.data with beforeRender the localization doesn't work anymore. If we disable the script with beforeRender the localization works.

Are the resources for localization stored in req.data and get overwritten with beforeRender?
Or what else might cause this behaviour?

Hi,

We have a report, which fetches data from a REST webservice with beforeRender. Sometimes this data is empty - resulting in an empty report (a complete white pdf).

Is it possible to exit report generation in beforeRender (if REST response is empty) and send a 204 status to the calling client?

Here some code:

function beforeRender(req, res, done) {
    require('request')({
        rejectUnauthorized: false, //Fehlerbehebung: UNABLE_TO_VERIFY_LEAF_SIGNATURE
        url: 'https://someurl/api/v2/something',
        json: true,
        encoding: 'utf8',
        method: 'POST',
        headers: {
            'Authorization': 'Basic abc123',
            'X-DreamFactory-Api-Key': 'abc123',
            'Accept': 'application/json'
        },
        body: {
            "params": [{
                "name": "loginin",
                "param_type": "IN",
                "value": req.data.loginin
            }],
            "wrapper": "data"
        }
    }, function(err, response, body) {
        if (err) {
            return done(err);
        }
        req.data = { items: body };
        done();
    });
}

Reto E.

Works perfect. Thx.
