# Dynamic Collections

Plex Meta Manager can dynamically create collections based on different criteria, such as
* Collections based on the Collections from TMDb for every item in the library. ([Star Wars](https://www.themoviedb.org/collection/10-star-wars-collection), [The Lord of the Rings](https://www.themoviedb.org/collection/119), etc...)
* Collections based on each of a Users Trakt Lists
* Collections for the top `X` popular people on TMDb (Bruce Willis, Tom Hanks, etc...)
* Collections for each decade represented in the library (Best of 1990s, Best of 2000s, etc...)
* Collections for each of the moods/styles within a Music library (A Cappella, Pop Rock, etc...)

The main purpose of dynamic collections is to automate the creation of collections which would otherwise require considerable user input and repetition (such as creating a collection for every genre).

Each dynamic collection must have a mapping name (just like standard collections), which is also attached to the collection as a label to mark it as having been created by this dynamic collection.

This example will create a collection for every TMDb Collection associated with items in the library.

```yaml
dynamic_collections:
  TMDb Collections:          # This name is the mapping name
    type: tmdb_collections
    remove_suffix: "Collection"
```

## Collection Naming

By default, the collections generated will be named for the thing being used to create them; things like genres, countries, actors or even Trakt List Names.

There are many attributes that can change the titles, including `title_format`, `remove_suffix`, `remove_prefix`, `pre_format_override`, and `post_format_override` all detailed below.

## Dynamic Keys & Titles

A `dynamic key` or `key` for short is used to refer to a specific value/result from the dynamic collection criteria that will be used to create the collection.

A `title` in this case is the name that replaces `<<title>>` in `title_format` to create the collection titles for each key.

An example of some keys that would be generated from a `genre` dynamic collection are; "Animation", "Horror" and "Comedy"

### Example Key Usage

Keys can be used for a number of purposes, examples can be found throughout this page. A few examples are shown below:

* Excluding the "Horror" key from the `Genre` dynamic collection definition

```yaml
dynamic_collections:
  Genres:         # mapping name does not matter, just needs to be unique
    type: genre
    exclude:
      - Horror
```

* Using the `keys` attribute to change the formatting of "France" to "French" so that a collection can be named "French Cinema" instead of simply "France"
  * This particular example also uses the `title_format` attribute to manipulate the naming convention of the collections.

```yaml
dynamic_collections:
  Countries:         # mapping name does not matter, just needs to be unique
    type: country
    title_format: <<country>> Cinema
    pre_format_override:
      France: French
```

* Using the `addons` attribute to combine multiple `keys`, i.e. merging "MTV", "MTV2", "MTV3" and "MTV (UK)" into one "MTV Worldwide" collection.
  * When doing this, individual collections will not be created for the individual MTV collections, instead they will be merged within the "MTV Worldwide" collection.

```yaml
dynamic_collections:
  networks:
    type: network
      addons:
        MTV Worldwide:
          - MTV
          - MTV2
          - MTV3
          - MTV (UK)
```

* `actor_minimum` determines the minimum number of times the actor must appear within `actor_depth` for the collection to be created.
* `number_of_actors` determines the number of actor collection to max out at. (i.e. if to make collections for the top 25 actors)

#### Example:

* Create a collection for the top 25 actors who appear in the top 5 billing credits of movies

```yaml
dynamic_collections:
  Top Actors:         # mapping name does not matter just needs to be unique
    type: actor
    data:
      actor_depth: 5
      number_of_actors: 25
```

#### Example:

* Create a collection for actors who appear in the top 5 billing credits of movies
* Only create the collection if they are in the top 5 billing credits of at least 20 movies

```yaml
dynamic_collections:
  Actors:         # mapping name does not matter just needs to be unique
    type: actor
    data:
      actor_depth: 5
      actor_minimum: 20
```

      limit: 10
      sort_by: plays.desc
      type: albums
      all:
        album_style: <<style>>
dynamic_collections:
  Styles:         # mapping name does not matter just needs to be unique
    type: style
    title_format: Top <<title>> Albums
    template: style collection
```

## Exclude

Exclude this list of `keys` from being created into collections.

For example when making a `genre` dynamic collection definition you can exclude "Horror" from having a collection created from the key.

```yaml
dynamic_collections:
  Genres:         # mapping name does not matter, just needs to be unique
    type: genre
    exclude:
      - Horror
```

## Addons

Defines how multiple `keys` can be combined under a parent key.

For example, the `addons` attribute can be used to combine multiple `keys`, i.e. merging "MTV", "MTV2", "MTV3" and "MTV (UK)" into one "MTV Worldwide" collection.
  * When doing this, individual collections will not be created for the individual MTV collections, instead they will be merged within the "MTV Worldwide" collection.

```yaml
dynamic_collections:
  networks:
    type: network
      addons:
        MTV Worldwide: 
          - MTV
          - MTV2
          - MTV3
          - MTV (UK)
```

## Template

Name of the template to use for these dynamic collections. Each `type` has its own default template, but if you want to define and use your own template you can.

For example, the template below removes the limit on the `smart_filter` so it shows all items in each network

```yaml
templates:
  network collection:
    smart_filter: 
      sort_by: critic_rating.desc
      all: 
        network: <<network>>
dynamic_collections:
  Networks:         # mapping name does not matter just needs to be unique
    type: network
    title_format: <<title>>
    template: network collection
```

## Template Variables

Defines how template variables can be defined by key.

For example, when using `type: tmdb_collections` and you want to define a poster url for some collections

```yaml
templates:
  optional:
    - my_collection_poster
  tmdb_collection_details: <<collection_id>>
  collection_order: release
  url_poster: <<my_collection_poster>>
dynamic_collections:
  TMDb Collections:          # This name is the mapping name
    type: tmdb_collections
    remove_suffix: "Collection"
    template_variables:
      my_collection_poster:
        119: https://www.themoviedb.org/t/p/original/oENY593nKRVL2PnxXsMtlh8izb4.jpg
        531241: https://www.themoviedb.org/t/p/original/nogV4th2P5QWYvQIMiWHj4CFLU9.jpg
```

## Remove Prefix/Suffix

Removes the defined prefixes/suffixes from the key before it’s used in the collection title.

For example, when using `type: tmdb_collections` you may not want every collection title to end with `Collection`

```yaml
dynamic_collections:
  TMDb Collections:          # This name is the mapping name
    type: tmdb_collections
    remove_suffix: "Collection"
```

## Title Format

This is the format for the collection titles.

there are two special tags you can include in the `title_format` 
* `<<title>>` is required and is what will be replaced by the dynamic title
* `<<library_type>>` will be replaced with either Movie, Show, or Artist depending on your library type.

Here's an example using `title_format`.

```yaml
dynamic_collections:
  Genres:         # mapping name does not matter just needs to be unique
    type: genre
    title_format: Top 50 <<title>> <<library_type>>s
```

## Pre Format Override

Defines how titles can be overridden before they are formatted into collection titles.

This example uses the `pre_format_override` attribute to change the formatting of "France" to "French" so that a collection can be named "French Cinema" instead of simply "France"
  * This particular example also uses the `title_format` attribute to manipulate the naming convention of the collections.

```yaml
dynamic_collections:
  Countries:         # mapping name does not matter, just needs to be unique
    type: country
    title_format: <<country>> Cinema
    pre_format_override:
      France: French
```

## Post Format Override

Defines how collection titles can be overridden ignoring title formatting.

Here's an example using `post_format_override` that will override the TMDb Star Wars collection which has an TMDb ID of `10` with `Star Wars Universe.

```yaml
dynamic_collections:
  TMDb Collections:          # mapping name does not matter, just needs to be unique
    type: tmdb_collections
    remove_suffix: "Collection"
    post_format_override:
      10: Star Wars Universe
```

## Test

Will add `test: true` to all collections for test runs.

Here's an example using `test`.

```yaml
dynamic_collections:
  Genres:         # mapping name does not matter just needs to be unique
    type: genre
    test: true
```

## Sync

Will remove dynamic collections that are no longer in the creation list.

The mapping name is added as a label to any collection created using dynamic and because of this when `sync` is true all collections with that label not found in this run will be deleted.

Here's an example using `sync`.

```yaml
dynamic_collections:
  Trakt Liked Lists:          # mapping name does not matter just needs to be unique
    type: trakt_liked_lists
    sync: true
```

## Include

Define a list of keys to be made into collections.

This cannot be used with `exclude`.

Here's an example using `include`.

```yaml
dynamic_collections:
  Genres:         # mapping name does not matter just needs to be unique
    type: genre
    include: 
      - Action
      - Adventure
      - Animation
      - Comedy
      - Family
      - Fantasy
      - Horror
      - Romance
      - Science Fiction
      - War
```

## Other Name

Used in combination with `include`. When defined, all keys not in `include` or `addons` will be combined into this collection.

This is the main reason to use `include`. It allows a catch all collection for everything not defined in the config file.

Here's an example using `other_name`.

```yaml
dynamic_collections:
  Genres:         # mapping name does not matter just needs to be unique
    type: genre
    other_name: Top Other Movies
    include:
      - Action
      - Adventure
      - Animation
      - Comedy
      - Family
      - Fantasy
      - Horror
      - Romance
      - Science Fiction
      - War
```
