Usage

Simply import the button into a toolbar, like so:

$3

``js
import {
Datagrid,
List,
TextField,
RichTextField,
TopToolbar,
} from "react-admin";
import { ImportButton } from "react-admin-import-csv";
import { CreateButton } from "ra-ui-materialui";

const ListActions = (props) => {
const { className, basePath } = props;
return (




);
};
export const PostList = (props) => (
} actions={}>



...


);
`

$3

`js
import {
Datagrid,
List,
TextField,
RichTextField,
TopToolbar,
} from "react-admin";
import { ImportButton } from "react-admin-import-csv";
import { CreateButton, ExportButton } from "ra-ui-materialui";

const ListActions = (props) => {
const {
className,
basePath,
total,
resource,
currentSort,
filterValues,
exporter,
} = props;
return (


disabled={total === 0}
resource={resource}
sort={currentSort}
filter={filterValues}
exporter={exporter}
/>


);
};
export const PostList = (props) => (
} actions={}>



...


);
`

Configuration Options

`typescript
// All configuration options are optional
const config: ImportConfig = {
// Enable logging
logging?: boolean;
// Disable the attempt to use "createMany", will instead just use "create" calls
disableCreateMany?: boolean,
// Disable the attempt to use "updateMany", will instead just use "update" calls
disableUpdateMany?: boolean,
// Disable the attempt to use "getMany", will instead just use "getSingle" calls
disableGetMany?: boolean,
// Disable "import new" button
disableImportNew?: boolean;
// Disable "import overwrite" button
disableImportOverwrite?: boolean;
// A function to translate the CSV rows on import
preCommitCallback?: (action: "create" | "overwrite", values: any[]) => Promise;
// A function to handle row errors after import
postCommitCallback?: (error: any) => void;
// Transform rows before anything is sent to dataprovider
transformRows?: (csvRows: any[]) => Promise;
// Async function to Validate a row, reject the promise if it's not valid
validateRow?: (csvRowItem: any) => Promise;
// Any option from the "papaparse" library
parseConfig?: {
// For all options see: https://www.papaparse.com/docs#config
}
}

`



Handle id fields which might be numbers



Use the paparse configuration option dynamicTyping

`js
const importOptions = {
parseConfig?: {
// For all options see: https://www.papaparse.com/docs#config
dynamicTyping: true
}
}
`



Reducing Requests (.createMany() and .updateMany())



Your dataprovider will need to implement the .createMany() method in order to reduce requests to your backend. If it doesn't exist, it will fallback to calling .create() on all items, as shown below (same goes for .update()):

| Name | Special Method | Fallback Method |
| ----------------- | ------------------ | --------------- |
| Creating from CSV | .createMany() | .create() |
| Updating from CSV | .updateManyArray() | .update() |
| Checking which exist | .getMany() | .getSingle() |

Note: You can disable this feature setting disableCreateMany: true or disableUpdateMany: true in the configuration.

$3

The dataprovider should accept these param interfaces for the bulk create/update methods.

`typescript
export interface UpdateManyArrayParams {
ids: Identifier[];
data: any[];
}
export interface CreateManyParams {
data: any[];
}
`

$3

Here's a quick example of how to implement .createMany() and .updateMany() in your dataprovider:

` js
// Must be react-admin 3.x
const dataProviderWrapped = {
...dataProvider, // <- Your data provider
createMany: async (resource, params) => {
const items = params.data;
// Handle create many here
},
updateMany: async (resource, params) => {
const items = params.data;
const idsToUpdate = params.ids;
// Handle update many here
}
}

// Pass into to other parts of the system as normal
return (
`



Translation i18n



This package uses react-admin's global i18n translation. Below is an example on how to set it up with this package.

Current supported languages (submit a PR if you'd like to add a language):

- English (en)
- Spanish (es)
- Chinese (zh)
- German (de)
- French (fr)
- Brazilian Portuguese (ptBR)
- Russian (ru)
- Dutch (nl)

Example (i18nProvider)

`jsx
import { resolveBrowserLocale, useLocale } from "react-admin";
import polyglotI18nProvider from "ra-i18n-polyglot";
import englishMessages from "ra-language-english";
// This package's translations
import * as domainMessages from "react-admin-import-csv/lib/i18n";

// Select locale based on react-admin OR browser
const locale = useLocale() || resolveBrowserLocale();
// Create messages object
const messages = {
// Delete languages you don't need
en: { ...englishMessages, ...domainMessages.en },
zh: { ...chineseMessages, ...domainMessages.zh },
es: { ...spanishMessages, ...domainMessages.es },
};
// Create polyglot provider
const i18nProvider = polyglotI18nProvider(
(locale) => (messages[locale] ? messages[locale] : messages.en),
locale
);

// declare prop in Admin component
