How can I switch from the first code to the second code?

I'm trying to switch from the first code to the second one I hope you can guide me.



speak more clearly

I'm trying to change the first 'req.body.dharma'

to the second 'return async (req, res) => {     let article = req.article     article.title = req.body.title     article.description = req.body.description     article.markdown = req.body.markdown'.

first code:

module.exports.updateDharma = async (req, res) => {
    const { id } = req.params;
    console.log(req.body);
    const dharma = await Dharma.findByIdAndUpdate(id, { ...req.body.dharma });
    const imgs = req.files.map(f => ({ url: f.path, filename: f.filename }));
    dharma.images.push(...imgs);
    await dharma.save()
    if(req.body.deleteImages){
        for(let filename of req.body.deleteImages){
            await cloudinary.uploader.destroy(filename);
        }
        await dharma.updateOne({ $pull: { images: {filename: { $in: req.body.deleteImages } } } } )
    }
    req.flash('infoDharma', 'อัปเดตสำเร็จ');
    res.redirect(`${dharma._id}`)
}
second code:

function saveArticleAndRedirect(path) {
  return async (req, res) => {
    let article = req.article
    article.title = req.body.title
    article.description = req.body.description
    article.markdown = req.body.markdown
    try {
      article = await article.save()
      res.redirect(`/articles/${article.slug}`)
    } catch (e) {
      res.render(`articles/${path}`, { article: article })
    }
  }
}
