Standalone fields - cannot get initial values to load and cannot save new values

Standalone fields - cannot get initial values to load and cannot save new values

HI,

I am trying hard to get the Standalone edit mode to work in my site, but am not getting very far. I hope someone who is more knowledgeable than I (this is not hard as I am a total novice) can help (@allan if you have time?) , or send me an example that I can work from to correct my mistakes.

The basic setup is I have a table that is used to store contacts (called 'recruits'), then I have a table that stores data about these contacts (called 'recruits_data'). Ideally, I want to show the 'recruits table in a datagrid, then when one row is selected, I want the standalone fields to populate with data from the 'recruits_data' table. I previously had this working flawlessly when using two datagrids (one for each table), but design requirements make using Standalone fields a much better fit for the application.

I am using Node.JS and the data is stored in mySQL.

The problems I am seeing are ;

  1. The data from the 'recruits_data' table does not populate the initial standalone fields. I have tried using both the INLINE and EDIT options.

  2. When saving a field, everything appears to work (no errors) but the data is not saved. I notice that the AJAX url is called correctly and the data appears correct, but the response looks like nothing occurred. See the data example below:

**Request: **

data[1][recruits_data][status]: New Recruit
action: edit
recruitID: 1

**Response : **
{"cancelled":[],"data":[],"fieldErrors":[],"debug":[]}

Here is my setup (note I use Jade/Pug, so the HTML will look a little strange, but it is fairly
easy to follow if you ignore the strangeness of the look.)

**HTML / Pug File **

Controller / Node.JS Route File

        } )

    await editor.process(req.body);
    res.json(editor.data());

});

module.exports = router;

Any Help, advice, or examples would be gratefully received. I does appear that using StandAlone would be perfect for my application, so I do hope someone can point me in the correct direction here.

thanks you so much,

    I didn't look at your code but I can share my experience. I never got standalone editing to work with Editor. My workaround is that I use Editor with invisible data tables that have one column and mostly just one row. Then everything works as usual even though it is a bit annoying to have that pseudo-data table stuff in the code.

    Thanks @rf1234

    That is funny, I was just starting to do that here. As if I create a table
    with a single field, and then hide the header, make it not sortable, it looks just like a standalone field and works perfectly. It's a shame to do it that way, but it will work.

    thanks for your comment.
