Overview

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 this tutorial page and on the LookML Terms and Concepts page.

This page explains how to configure a model in a project. Configuring a model:

  • Specifies that a given model name refers to a particular model in a particular project
  • Sets which connections the model is allowed to use

Although a developer specifies the desired connection in the model file, an admin controls what connections are allowed on the LookML Project page. Thus, a model should only use a connection that the configuration allows because the configuration always wins. If a model specifies using a connection that is not allowed in the model’s configuration, then the connection is not allowed.

LookML Projects lets you view all of your projects in one place, along with their respective models. You use this page to view and configure your projects.

When You Need to Configure Models

  • When Pushing a Model to Production The First Time

    In production mode, the model must be configured or else any queries on that model will fail.

    When a model is pushed from development mode to production for the first time, Looker often is able to configure it for you automatically. This is possible when the model’s name is unique for the Looker instance. However, if you already have a configured model with the same name in another project, then Looker will not automatically configure the model.

  • During Development

    If you have developers who have not been given the manage_models permission (which is included in the admin role) then the model must be configured before those developers can run queries on that model.

    In this case, you can configure the model before the model exists or even before the project exists. Then when a developer creates the project and the model, the model’s allowed connections are already configured and the developer can run queries successfully.

    For developers without manage_models permission, admins can limit their access to certain connections by limiting the developers to particular model sets and limiting the connections allowed for those models.

    However, Looker allows anyone who has been given the manage_models permission to run queries on an unconfigured model in development mode. Looker does this by searching projects for a model with that name. The first model it finds with that name is used to run the query.

Accessing the LookML Projects Page

To access the LookML Projects page, click the Develop menu and choose Manage LookML Projects.

Effect of Permissions

Each user may see a different list of projects and models on this page, based on their permissions.

Effect of Development Mode

You may see additional entries on this page when you view it in development mode versus production mode. For example, if you created a new model in development mode that you have not yet pushed to production then that model would be visible only when you are in development mode.

A model configuration is not needed for admins (or developers with the manage_models permission) while they are in development mode. This lets developers work easily while in development mode. However, if a model configuration does exist, any queries will be constrained by that configuration even in development mode.

Viewing Existing Projects and Their Models

The projects listed in the Projects section are limited to those projects that:

  • Already exist

    If you are in production mode, then the project must have been generated and pushed to production. If you are in development mode, then you pulled the project from production or you generated the project in your development mode.

  • Has at least one model that you are allowed to develop

    You have develop permission for a model set that includes at least one model in the project. Alternatively, having the manage_models permission gives you access to view the project.

On the LookML Project page, anyone with manage_models permission can add or edit model configurations for any models listed for the projects. You can choose which connections a model is allowed to use:

  • a list of specific connections or
  • any connection (all current and future connections)

Specifying a new project or a new model for an existing project is described later on this page.

The Projects section, shown below, is described in the following sections.

Project Name

This is the name of the project. Each project may have one or more models listed next to it. You can click on the project name to navigate to the LookML for that project.

Models

The set of LookML model files for the given project.

Please note that if your development mode environment differs from production, this list can change between development mode and production mode. For example, if you might have created a new model in development mode that you have not yet pushed to production.

Configuration Issues

Each model in a project will have a status showing any problems with the configuration.

Issue Explanation
OK This is the desired state
Missing LookML Model You see this issue if someone configured a model on this page but has not yet created a corresponding LookML file for it
Not Configured You see this issue if someone created a new LookML model file in an existing project, but has not configured it on this page yet
Connection ‘x’ does not exist The connection declared in the model file does not exist (such as if someone misspelled it or has not created it yet)
Model ‘x’ is not allowed to use connection ‘y’ The connection declared in the model file is not permitted according to the configuration on this page
A model named ‘x’ is already configured in project ‘y’ Model names must be unique within your Looker instance, even if they are in different projects

Type

The Type column specifies whether the project uses the older YAML-based LookML or uses New LookML.

Add Configuration

Use this link to add a model configuration. On the destination page, you can specify the model name, project name, and specify which connections are available to the model.

Edit Configuration

Use this link to edit your model configuration. On the destination page, you can change which connections are available to the model.

You can view the model name but not rename it. Models are named according to the filenames you use in the Models section of the Looker IDE, as described here).

You can also specify that the model should be associated with a different project. For example, if you created a new project including a model with the same name, you can transition the model configuration to be associated with the new project’s model.

Delete Project

Using the Delete Project button will remove the project from all development and production environments across your Looker instance.

Please be certain you want to delete a project before you do so. It cannot be undone and is difficult and laborious to recover.

Viewing Projects with Only a Configuration

The Configured Projects (Ready to add LookML) section contains model configurations that were specified with a project name where the project has not been generated yet.

Thus the Configured Projects (Ready to add LookML) section contains projects and models that are only configured, that do not yet have any LookML.

Configuring models before the project exists is useful if you have developers who have not been given the manage_models permission. Because the model has already been configured, those developers will be able to run queries as soon as they create the project and that model. When the project is generated, the listing for that project moves to the top Projects section.

The Configured Projects section, shown below, is described in the following sections.

Project Name

This section lists projects that are configured but not yet generated, so the project name in this field is the intended name of the project when it is later generated. Clicking the project name takes you to the New Project page where you can generate that project. You must be in development mode to reach the New Project page.

Models

This is the model name that was specified when creating the model configuration.

Allowed Connections

These are the connections that were allowed for this model when creating the model configuration.

Edit Configuration

This link lets you change the project name and the connections that are permitted for this model.

Creating New Projects and Model Configurations

Use the buttons at the bottom of this page to generate a project or configure a model.

Configuring a New LookML Project

Use the New LookML Project button to create a new project using the LookML generator. You must be in Development mode to create a new project.

Looker asks for the connection on this page so that it can automatically generate LookML based on a set of tables in your database. However, you can still add additional connections later.

The LookML Type field only appears if the YAML-based LookML legacy feature is on. In this field, you can specify whether you want the project to use New LookML or the older YAML-based LookML. If the legacy feature is off (the default setting) then the project will be created using New LookML. For more information about the benefits of using New LookML, see this article.

Configuring a Model

Use the Configure a Model button to add a configuration for an existing or planned model.

Configuring a model for a project that doesn’t exist yet is useful when the developers has not been given the manage_models permission as they’ll be able to run queries as soon as they generate or create the model file.

You can also specify which database connections are allowed to be used by the model or specify that the model can use any current or future connections. If a developer uses the LookML connection LookML parameter in the model file to specify a connection that is not allowed in the model configuration, then any query on that model will not run.
