    On the client-side listen for postSubmit and check the cancelled array in the JSON data. Any rows that were rejected will be listed there. You can then use error() or alert() to show a message to the user.

    There is no option for either at this time. I figured that you would always want to be showing all options in the list, since each will be unique.

    If you wanted to use distinct or groupBy you could either define a VIEW with them, and then read the results from that view, or use a custom function to get the options from the database and query it directly (i.e. with Knex, giving you the full list of options it has available).

    hi,Allan.
    I have a problem again. in bubble edit,if use leftJoin to link another table,click the linked table cell,console display error above.
    dataTables.editor.min.js:66 Uncaught Unable to automatically determine field from source. Please specify the field name. For more information, please refer to https://datatables.net/tn/11

  • allanallan Posts: 50,842Questions: 1Answers: 7,620 Site admin

    Hi,

    The page the error links to provides a detailed describe of the problem and how to resolve it. Basically the columns.data for the DataTable column and field.name for the Editor field don't match, so you need to tell DataTables which field you want to edit when that column is activated.

    web page:

    editor.fields: [
                         {
                            label: "批次:",
                            name: "capsule_pp_capsuleproductsub.BatchNO",
                            type: "select",
                            placeholder: "选择批次"
    
                        },
    
    table. columns: [
                        { data: "capsule_pp_capsuleproduct.BatchNO" },
    

    server :

         editor.Field('capsule_pp_capsuleproductsub.BatchNO')
                .options(
                    new Options()
                    .table('capsule_pp_capsuleproduct')
                    .value('id')
                    .label('BatchNO')
                ),
    .leftJoin('capsule_pp_capsuleproduct', 'capsule_pp_capsuleproduct.id', '=', 'capsule_pp_capsuleproductsub.BatchNO')
    

    namly, editor have not field"capsule_pp_capsuleproduct.BatchNO",then can't use bubble edit method on the field,isn't?

    thanx,Colin.
    But my image is too big,display it will to occupy almost totall webpage.

  • colincolin Posts: 6,818Questions: 0Answers: 1,167

    Hi @wm1111 ,

    Ah, I see. This thread here (and here) talks about how to create a thumbnail, you need to create an action to do it. Then this section of the manual explains how to display it.

    Cheers,

    Colin
