Views
Views sit on top of the data graph of cubes and create a facade of your whole data model with which data consumers can interact. They are useful for defining metrics, managing governance and data access, and controlling ambiguous join paths.
Any view should have the following parameters: name
and cubes
.
Parameters
name
The name
parameter serves as the identifier of a view. It must be unique among
all cubes and views within a deployment and follow the naming
conventions.
views:
- name: active_users
description
This parameter provides a human-readable description of a view. When applicable, it will be displayed in Playground and exposed to data consumers via APIs and integrations.
A description can give a hint both to your team and end users, making sure they interpret the data correctly.
views:
- name: active_users
description: 14 days rolling count of active users
cubes
Use cubes
parameter in view to include exposed cubes in bulk. You can build
your view by combining multiple joined cubes together and specifying the path by
which they should be joined for that particular view.
views:
- name: orders
cubes:
- join_path: base_orders
includes:
- status
- created_date
- total_amount
- total_amount_shipped
- count
- average_order_value
- join_path: base_orders.line_items.products
includes:
- name: name
alias: product
- join_path: base_orders.users
prefix: true
includes: "*"
excludes:
- company
join_path
When listing cubes to expose, you need to provide a join_path
parameter.
It uses the "dot notation" to describe the join path: cube_1.cube_2.cube_3
.
For the root cube of the view, just use the cube name as in the example
above for base_orders
.
includes
and excludes
The other required parameter inside the cubes
block is includes
. Use it
to list measures, dimensions, or segments you'd like to include into the view.
To include all members from a cube, use the includes all shorthand: includes: "*"
.
In that case, you can also use the excludes
parameter to list members that
you'd like to exclude.
alias
Optionally, in case you need to rename some of included members, you can provide
name
and alias
parameters.
prefix
Optionally, if you'd like to prefix exposed measures, dimensions, or segments
with the cube name, you can use the prefix: true
parameter. It will prefix
them with the cube name, e.g. users_city
. You can use the alias
parameter to
specify a custom prefix.
folders
The folders
parameter is used to organize members of a view (e.g., dimensions,
hierarchies, measures, etc.) into logical groups. Folders can contain non-overlapping
subsets of members from a view.
Folders display is subject to support in visualization tools. Check APIs & Integrations for details. You can also preview folders in Playground.
Each folder should specify a human-readable name via the name
parameter and list
included members via the includes
parameter:
views:
- name: customers
cubes:
- join_path: users
includes: "*"
- join_path: users.orders
prefix: true
includes:
- status
- price
- count
folders:
- name: Basic Details
includes:
- created_at
- location
- orders_status
- orders_count
- name: Sensitive Details
includes:
- name
- gender
public
The public
parameter is used to manage the visibility of a view. Valid values
for public
are true
and false
. When set to false
, this view cannot
be queried through the API. Defaults to true
.
views:
- name: orders
public: false
You can also use COMPILE_CONTEXT
for dynamic visibility if necessary, check
out our
Controlling access to cubes and views
recipe.
views:
- name: arr
description: Annual Recurring Revenue
public: COMPILE_CONTEXT.security_context.is_finance
cubes:
- join_path: revenue
includes:
- arr
- date
- join_path: revenue.customers
includes:
- plan
To learn more about using public
to control visibility based on security
context, read the Controlling access to cubes and views
recipe.
meta
Custom metadata. Can be used to pass any information to the frontend.
views:
- name: active_users
meta:
any: value
access_policy
The access_policy
parameter is used to configure data access policies.
