Import CSV give None/Blank option and submit blank on submission

Import CSV give None/Blank option and submit blank on submission

I am using the CSV Import set up in the example here
I am changing it slightly, as I want to control/premap the fields a bit for the most part. I want to provide an option of 'none' or blank though for the select. I have done so looking at posts from here and here

This works, but the problem is, when you get to the multi-edit form, any field on the 'None/Blank' column submits a 3. I can't figure out how to make this submit empty. Here is the code for the setup of the import:


// GMail CSV - Display an Editor form that allows the user to pick the CSV data to apply to each column function selectGMAILColumns ( GMAILImport, csv, header ) { header.push(''); selectGMAILImport = new $.fn.dataTable.Editor( { fields: [ { "label": "Prefix:", "name": "prefix", "type": 'hidden' }, { "label": "First Name:", "name": "first_name", "type": 'select', "options": header, "def": 'Given Name' }, { "label": "Middle Name:", "name": "middle_name", "type": 'hidden', "def": '' }, { "label": "Last Name:", "name": "last_name", "type": 'select', "options": header, "def": 'Family Name' }, { "label": "Suffix:", "name": "suffix", "type": 'select', "options": header, "def": 'Name Suffix' }, { "label": "Title:", "name": "title", "type": 'select', "options": header, "def": 'Organization 1 - Title' }, { "label": "Company Name:", "name": "company_name", "type": 'select', "options": header, "def": 'Organization 1 - Yomi Name' }, { "label": "Home Phone:", "name": "home_phone", "type": 'hidden', "def": '' }, { "label": "Mobile Phone:", "name": "mobile_phone", "type": 'select', "options": header, "def": 'Phone 1 - Value' }, { "label": "Work Phone:", "name": "work_phone", "type": 'hidden', "def": '' }, { "label": "Fax:", "name": "fax_phone", "type": 'hidden', "def": '' }, { "label": "Personal Email:", "name": "personal_email", "type": 'select', "options": header, "def": 'E-mail 1 - Value' }, { "label": "Work Email:", "name": "work_email", "type": 'hidden', "def": '' }, { "label": "Street:", "name": "street", "type": 'hidden', "def": '' }, { "label": "City:", "name": "city", "type": 'hidden', "def": '' }, { "label": "State:", "name": "state", "type": 'hidden', "def": '' }, { "label": "Postal Code:", "name": "postal_code", "type": 'hidden', "def": '' }, { "label": "Source:", "name": "source", "className": "", "type": "hidden", "def": "Initial Market" }, { "label": "MOD Email:", "name": "mod_email", "type": "hidden", "def": "" }, { "label": "Street 2:", "name": "street2", "type": "hidden", "def": "" }, { "label": "Index Count:", "name": "index_count", "className": "", "type": "hidden", "def": "2" } ] }); selectGMAILImport.create({ title: 'Map CSV fields', buttons: 'Import '+csv.length+' records', message: 'Select the CSV column you want to use the data from for each field.' }); selectGMAILImport.on('submitComplete', function (e, json, data, action) { // Use the host Editor instance to show a multi-row create form allowing the user to submit the data. GMAILImport.create( csv.length, { title: 'Confirm import', buttons: 'Submit', message: 'Click the <i>Submit</i> button to confirm the import of '+csv.length+' rows of data. Optionally, override the value for a field to set a common value by clicking on the field below.' } ); for ( var i=0 ; i<fields.length ; i++ ) { var field = GMAILImport.field( fields[i] ); var mapped = data[ field.name() ]; for ( var j=0 ; j<csv.length ; j++ ) { field.multiSet( j, csv[j][mapped] ); } } } ); } // GMAIL CSV - Regular editor for the table GMAILImport = new $.fn.dataTable.Editor( { table: '#p200table', ajax: function ( method, url, d, successCallback, errorCallback ) { var output = { data: [] }; if ( d.action === 'create' ) { // Create new row(s), using the current time and loop index as // the row id var dateKey = +new Date(); $.each( d.data, function (key, value) { var id = dateKey+''+key; value.DT_RowId = id; localSave[ id ] = value; output.data.push( value ); } ); } else if ( d.action === 'edit' ) { // Update each edited item with the data submitted $.each( d.data, function (id, value) { value.DT_RowId = id; $.extend( localSave[ id ], value ); output.data.push( localSave[ id ] ); } ); } else if ( d.action === 'remove' ) { // Remove items from the object $.each( d.data, function (id) { delete localSave[ id ]; } ); } // Store the latest `localSave` object for next reload localStorage.setItem( 'localSave', JSON.stringify(localSave) ); // Show Editor what has changed successCallback( output ); }, fields: [ { "label": "Prefix:", "name": "prefix", "type": 'hidden' }, { "label": "First Name:", "name": "first_name" }, { "label": "Middle Name:", "name": "middle_name", "type": 'hidden', "def": '' }, { "label": "Last Name:", "name": "last_name" }, { "label": "Suffix:", "name": "suffix" }, { "label": "Title:", "name": "title" }, { "label": "Company Name:", "name": "company_name" }, { "label": "Home Phone:", "name": "home_phone", "type": 'hidden', "def": '' }, { "label": "Mobile Phone:", "name": "mobile_phone" }, { "label": "Work Phone:", "name": "work_phone" }, { "label": "Fax:", "name": "fax_phone", "type": 'hidden', "def": '' }, { "label": "Personal Email:", "name": "personal_email" }, { "label": "Work Email:", "name": "work_email", "type": 'hidden', "def": '' }, { "label": "Street:", "name": "street", "type": 'hidden', "def": '' }, { "label": "City:", "name": "city", "type": 'hidden', "def": '' }, { "label": "State:", "name": "state", "type": 'hidden', "def": '' }, { "label": "Postal Code:", "name": "postal_code", "type": 'hidden', "def": '' }, { "label": "Source:", "name": "source", "className": "", "type": "hidden", "def": "Initial Market" }, { "label": "MOD Email:", "name": "mod_email", "type": "hidden", "def": "" }, { "label": "Street 2:", "name": "street2", "type": "hidden", "def": "" }, { "label": "Index Count:", "name": "index_count", "className": "", "type": "hidden", "def": "2" } ] } ); var fields = GMAILImport.order(); for ( var i=0 ; i<fields.length ; i++ ) { var field = GMAILImport.field( fields[i] ); } // Generic CSV - Upload Editor - triggered from the import button.

    Its not obvious where the 3 would be coming from in the above I'm afraid. Could you give me a link to your page showing the issue? I'm also not clear on what you mean by "any field on the 'None/Blank' column" - I don't see a "None/Blank" column?

    Yeah, it is difficult to show a demo of my setup at this point and i am struggling to get something built in the demo area, but will try to get one.

    I have added a blank option by doing

    header.push('');

    Then I use the new header as the choices for the option on the selects, so that there is a blank entry to choose on each drop down when selecting fields to map.

    The 3 appears when i do not select a column, but the push value or blank. If I run:
    field.multiSet(j, csv[j][mapped]);

    in the console, I get a value of 3 back so I think it is related to that and hoping there is a way to get it to submit nothing to those fields in that case. Will circle back when I can get a proper test case though.

    Alright, so I found an example colin had made of importing for someone else and cloned it and made the simple change of adding the push so that there is a blank option on the field drop downs when doing the matching. In this case it shows as a 7.

    The goal here is to let the user leave a field blank for mapping, and no data be submitted to that field, but the others are created as normal.

    Answer ✓

    I ran your example through the browser's debugger. If I choose the blank option for office I see this when the loop is processing the office column:

    The statement field.multiSet( j, csv[j][mapped] );, specifically csv[j][mapped], doesn't point to a valid object in the csv variable so the value returned could be anything. You will need to check to make sure mapped points to a valid object.

    One way is to do something like this:

    `field.multiSet( j, mapped ? csv[j][mapped] : "" );
    

    For example:
    http://live.datatables.net/vukofome/2/edit

    Or you can use a more comprehensive test before using the field.multiset() method.
