reshmajacob93

Hi sir,
i have found below script which check asset (image) exist, if asset not exist then an alternate image will be used. But in my case i have to check whether an asset exist in particular path.But i dont know how to filter document store using asset path?

const jsreport = require('jsreport-proxy')
async function beforeRender(req, res) {
const logoAsset = await jsreport.documentStore.collection('assets').findOne({ name: 'logo.png' })
if (logoAsset) {
req.data.logoAsest = 'logo.png'
} else {
req.data.logoAsest = 'another.png'
}
}

Could you please reply with an example?

    const jsreport = require('jsreport-proxy')
    const searchResult = await jsreport.folders.resolveEntityFromPath('/myasset.txt', 'assets')
    if (searchResult) {
        req.template.content = searchResult.entity.content.toString()
    }
}
