1
yarn build --clean

or

1
npm run build --clean

Usage

Once the plugin is installed and setup, the functionnalities for a collection are accessible on its content management page.

UI

You can also export the whole database from the home page of the plugin.

UI

Access Control

You can define which roles can import and/or export data from the admin UI.

Go to Settings > Roles (under Administration Panel) > Plugins > Import-export-entries.

UI

Admin view.


UI

User view of the plugin home page that can only export data.


UI

User view of the content management page that can only export data.

Preferences

For a quick and convenient use, you can set your preferences from the home page of the plugin.

UI

Once set, they will be used each time you import/export data.

      /**

       * when importing data.
       *
       * `idField` must match the name of an attribute.
       * See section _Specifying `idField` Per Collection_ for more details
       */
      "idField": "name"
    }
  },
  "attributes": {
    /**
     * In this example, `name` will be used to find an entry
     * of this collection when importing data.
     */
    "name": {
      "type": "string",
      "unique": true
    },
  }
}

Specifying idField Per Collection

Importing data will either create entries if they don't exist, or update them otherwise.

When transfering data from a database to another, relying on the id of an entry is not reliable. For example, if you are transfering data on hospitals with this schema:

1
2
3
4
5
6
interface Hospital {
  id: number;
  name: string;
  employees: Employee[];
  patients: Patient[];
}

You will have something similar in your source and target databases:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
// data in source database
{
  id: 1,
  name: "Pitié Salpêtrière",
  employees: [2, 3],
  patients: [4, 5],
}

// data in target database
{
  id: 11,
  name: "Pitié Salpêtrière",
  employees: [12, 13],
  patients: [14, 15],
}

Different databases, different ids. 🫠

That's why we need a way to define the field used to find an entry in a collection. This field is called an idField.

To define the idField of a collection, add it in the pluginOptions of the collection, under the property import-export-entries. Using the example above, this is how we would define the idField of the collection hospital:

1
2
3
4
5
6
7
8
9
10
11

{
  "collectionName": "hospitals",
  "info": {
    "displayName": "Hospital",
  },
  "options": {},
  /**
   * In the property `pluginOptions`, define the `idField` under the property `import-export-entries`.
   *
   * `idField` must match the name of an attribute.
   */
  "pluginOptions": {
    "import-export-entries": {
      "idField": "name"
    }
  },
  "attributes": {
    "name": { // 👈 `name` will be used to find a hospital when importing data.
      "type": "string",
      "unique": true
    },
    "employees": {
      "type": "relation",
      "relation": "oneToMany",
      "target": "api::employees.employees"
    },
    "patients": {
      "type": "relation",
      "relation": "oneToMany",
      "target": "api::patients.patients"
    },
  }
}

For each collection of your application, you can define a different idField. For example, you can set the name attribute as the idField of the collection hospital, and for the collection patients use the attribute ssn (I really hope you're not storing uncyphered SSNs in your database 😬).

How does the search behave if I don't define explicitly the idField of a collection?

By default, the idField of a collection is the id attribute. We can imagine in a near future to automatically detect unique scalar fields of a collection and use them by default, but it's not the case at the moment.

How does the search behave when I specify the idField from the strapi admin UI?

The idField specified from the import modal of the admin UI takes precedence over the one defined in the pluginOptions of the collection.

This default behavior could change in the future if user feedback shows it's cumbersome to set it manually on each import. You tell me.

Importing Large Files

When importing data, imported file size may exceed the file size limit of the server. To lift up the limit, configure the Strapi middleware body:

1
2
3
4
5
6
7
8
9
10
11
12
// ./config/middlewares.js

module.exports = {
  // ...
  {
    name: 'strapi::body',
    config: {
      jsonLimit: '10mb',
    },
  },
  // ...
}

Filtering and Sorting

The filtering and sorting mechanism relies on Strapi filtering and sorting feature:

  1. Connect to the content manager page of the model you want to export, and filter and sort the data as you want it to be exported.

UI

  1. Open the export modal and check the option Apply filters and sort to exported data.

UI

  1. Click on Fetch Data.

The exported data is filtered and sorted as expected.

Webhook

At the moment, the webhook is triggered only for media creation, update and deletion. It is not triggered for other data.

Importing Data

JSON v2

JSON v2 introduces a new supported file structure. Data is flattened and dependencies only relies on ids (objects are not supported in this new version). Collection types, single types, media and components are all treated the same for ease of use.

        "id": 2
        //...
      }
    }
  }
}

JSON v1 (deprecated)

The expected import data structure:

Relation:

object

the relation is searched in db by id. If an entry is found, it is updated with the provided data. Otherwise, it is created.

number

The relation is treated as an id.

Media:

object

the media must have an id, hash, name or url property. First the media is searched by id, then by hash, then by name and finally imported from url if not found previously.

When imported by url, the hash and name of the file are deduced from the url (the hash is also deduced because Strapi exports files with their hash in the url instead of the name). The hash and name are used to find the media in db. First the media is searched by hash, then by name and used if found. Otherwise, the media is uploaded to the db by downloading the file from the url.

⚠️ Check the server has access to the url.

When imported by url, extra data can be provided to enhance the created file:

  • id (defaults to an auto generated id)
  • name (defaults to the name deduced from the url)
  • caption (defaults to "")
  • alternativeText (defaults to "")

Examples

  • { id: 1 }
  • { hash: "alpaga.jpg" }
  • { name: "alpaga.jpg" }
  • { url: "https://www.thetimes.co.uk/imageserver/image/alpaga.jpg" } (Deduced file hash is alpaga and deduced name is imageserver-image-alpaga.jpg)
  • { url: "http://localhost:1337/alpaga.jpg" } (Deduced file hash is alpaga and deduced name is alpaga.jpg)
  • { id: 734, url: "http://localhost:1337/alpaga.jpg", name: "Alpacool", caption: "Alpacool In Da Hood", alternativeText: "Alpacool in da hood" }

string

Same as above, except the media provided is treated as a url.

  • "https://www.thetimes.co.uk/imageserver/image/alpaga.jpg" (Deduced file hash is alpaga and deduced name is imageserver-image-alpaga.jpg)
  • "http://localhost:1337/alpaga.jpg" (Deduced file hash is alpaga and deduced name is alpaga.jpg)

number

The media is treated as an id.
