Creating a new LookML project

A project is a collection of LookML files that describe how your database tables are related to each other and how Looker should interpret those tables. You can learn more about projects on the LookML projects and development model and LookML terms and concepts documentation pages. For information about accessing and editing existing projects, see the Accessing and editing project information documentation page.

A LookML project can contain more than one model file. However, if you want to specify permissions for users around seeing and editing LookML for a specific model file, you might want to create a new project. Although most permissions in Looker apply at the model level, there are some permissions that apply to the project level, including see_lookml, which lets you view LookML for a project, and develop, which lets you edit the LookML.

Looker users with the manage_models permission can create LookML models on a Looker instance.

Creating a project

Caution: The New Project page in Looker that is described in this documentation has been replaced with the Create a Model page. However, you can still access the New Project page if you are using a Looker (original) instance and your Looker admin has enabled the Use Legacy Project Creation Page legacy feature, or through the informational banner at the top of the Create a Model page, or from the Add LookML button in the Pending Projects section of the Projects page.

To create a project, perform the following steps:

1. Verify that you are in Development Mode.

2. Select Projects from the Develop section of the navigation panel.

   

3. On the LookML Projects page, select New LookML Project to select the options for your project.

   

This action opens the New Project page, where you can specify settings for your project, including the project's name and starting point.

Looker can create a project in several ways, and the steps taken depend on the Starting Point option that you choose on the New Project page. The following sections describe how these starting points work:

• Automatically generating a model from your database
• Cloning a public Git repository
• Creating a blank project

Automatically generating a model from your database

From the New Project page, specify the following options to automatically generate a model from a database.

1. Project Name: Give your project a name. Project names are case-sensitive and only allow alphanumeric characters, _, ., and -. Choose the project name carefully and consider it a permanent ID for the project, since Looker uses the project name in the following ways:

   • To identify the project for API calls that have the project_id parameter.
   • To identify the project in the Looker instance's internal database.
   • To identify the project for local project import.
   • To display the project on the LookML Projects page.
   • To display the project in the Develop section of the Looker navigation panel.
   • As part of the URL for project files. For example, on a Looker instance with a URL of example.looker.com, the project manifest file for the project named ecommerce can be found at this URL: https://example.looker.com/projects/ecommerce/files/manifest.lkml.

2. Starting Point: Choose Generate Model from Database Schema.

3. Connection: From the drop-down menu, select the name of your database connection.

4. Build Views From: Select one of the following options:

   • All Tables: The LookML generator creates a view file for each table in your database.
   • Single Table: The LookML generator creates a view for one table in your database. If you choose this option, enter the name of the database table.

5. Schemas: To generate files for only one schema in your database, enter the name of the schema in the Schemas text field. You can list multiple schemas, separated by commas.

   Note: For connections to Databricks databases with Unity Catalog enabled, Looker can generate models only for the Databricks catalog that is specified in the Looker connection to the Databricks database. If your connection doesn't specify a catalog, Looker can generate models only for your database's default catalog.

6. Ignore Prefixes: To leave table prefixes out of your view file names, enter your database's prefixes in the Ignore Prefixes field. This field is case-sensitive. You can list multiple prefixes, separated by commas. For example, your tables are titled dwh_orders and DBS_users. If you enter dwh, DBS in the Ignore Prefixes text field, then Looker creates view files named orders and users.

Finally, click Create Project to create a project that contains the generated model.

• The LookML generator creates one model file for the project as well as a view file for each table in the database (unless otherwise specified). Then, Looker opens the new project in the Looker IDE.
• The LookML generator creates IDE folders for your view and model files. If your database has more than one schema, the LookML generator creates a folder for schemas.

For BigQuery connections, if you generate a LookML project from your database, Looker autopopulates field descriptions with the descriptions from your BigQuery column metadata, if any.

The generator also creates an Explore for each database table. To start querying your data, use the Explore panel to select the name of an Explore.

Cloning a public Git repository

If you select Clone Public Git Repository as the starting point, Looker will copy the files from a public Git repository into your new LookML project.

Looker projects that are cloned from public Git repositories are read-only. However, you can import the read-only project into another of your Looker projects, where you can then edit the files. Additionally, you can use the cloned repository files as a starting point, then use the Looker extends parameter or refinements to build up a project from there.

From the New Project page, specify the following options to clone an existing public Git repository into a Looker project:

1. Project Name: Give your project a name. Project names are case-sensitive and cannot use spaces or certain special characters. Choose the project name carefully and consider it a permanent ID for the project, since Looker uses the project name in the following ways:

   • To identify the project for API calls that have the project_id parameter.
   • To identify the project in the Looker instance's internal database.
   • To identify the project for local project import.
   • To display the project on the LookML Projects page.
   • To display the project in the Develop section of the Looker navigation panel.
   • As part of the URL for project files. For example, on a Looker instance with a URL of example.looker.com, the project manifest file for the project named ecommerce can be found at this URL: https://example.looker.com/projects/ecommerce/files/manifest.lkml.

2. Starting Point: Choose Clone Public Git Repository.

3. Git Repository URL: Enter the URL for the public Git repository. Make sure that the URL is in the format git://github.com/example/my-repository.git.

   If you have a URL such as https://github.com/llooker/blocks_redshift_admin, you can edit it use to the correct format by replacing "https://" with "git://" and then adding ".git" at the end. The URL you would enter would be git://github.com/llooker/blocks_redshift_admin.git.

Finally, click Create Project. Looker will pull all the public repository's files into a new LookML project and open the project in the Looker IDE.

Creating a blank project

If you select Blank Project as the starting point, Looker creates an empty project so that you can create your LookML files from scratch.

From the New Project page, specify the following options to create a blank project:

1. Project Name: Give your project a name. Project names are case sensitive and cannot use spaces or certain special characters. Choose the project name carefully and consider it a permanent ID for the project, since Looker uses the project name in the following ways:

   • To identify the project for API calls that have the project_id parameter.
   • To identify the project in the Looker instance's internal database.
   • To identify the project for local project import.
   • To display the project on the LookML Projects page.
   • To display the project in the Develop section of the Looker navigation panel.
   • As part of the URL for project files. For example, on a Looker instance with a URL of example.looker.com, the project manifest file for the project named ecommerce can be found at this URL: https://example.looker.com/projects/ecommerce/files/manifest.lkml.

2. Starting Point: Choose Blank Project.

Finally, click Create Project. Looker creates the project and opens it in the Looker IDE.

Next steps

After a project is created, you can:

• Manually create additional new models for your project.
• Edit existing LookML files.
• Configure models for use in production.
• Rename the project.
• Connect the Looker project to Git.
