# 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), 
[Harry Potter](https://www.themoviedb.org/collection/1241), 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).

## Using Dynamic Collections

Each dynamic collection definition creates a set of collection definitions based on some given criteria and uses either 
the built-in default template or a user defined custom template to dynamically create collection definitions.

#### 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.

To change the name of the collection, you can use dynamic collection attributes including `title_format`, 
`remove_suffix`, `remove_prefix`, `key_name_override`, and `title_override` all detailed below.

#### Dynamic Keys & Key Names

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 `key_name` is the name that replaces `<<key_name>>` in `title_format` to create the collection titles for each key.

An example of some keys and their names that would be generated from a `tmdb_collection` dynamic collection are:

* `key`: "10"

    * `key_name`: Star Wars Collection

* `key`: "1241"

    * `key_name`: Harry Potter Collection

| `key` | `key_name`              |
|:------|:------------------------|
| 10    | Star Wars Collection    |
| 1241  | Harry Potter Collection |


### 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 `key_name_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: <<key_name>> Cinema
    key_name_override:
      France: French
```

* Using the `addons` attribute to combine multiple `keys`, i.e. merging "MTV2", "MTV3" and "MTV (UK)" into one "MTV" 
collection.

    * When doing this, individual collections will not be created for the individual MTV collections, instead they will
    be merged within the "MTV" collection.

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

## Dynamic Collection Definition

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

??? example "Dynamic Collection Example (click to expand)"

    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_collection
        remove_suffix: "Collection"
    ```

## Attributes

??? blank "`type` & `data` - Used to specify the type of Dynamic Collection.<a class="headerlink" href="#type-data" title="Permanent link">¶</a>"

    <div id="type-data" />Used to specify the type of Dynamic Collection and its data. `type` is required for every 
    dynamic collection and `data` is required for any type that uses the attribute.
    
    <hr style="margin: 0px;">
    
    **Attribute:** `type` & `data`
    
    **Accepted Values:** See [Dynamic Collection Types & Data](dynamic_types.md)

??? blank "`exclude` - Used to exclude a list of keys from being created into collections.<a class="headerlink" href="#exclude" title="Permanent link">¶</a>"

    <div id="exclude" />Used to exclude a list of `dynamic keys` from being created into collections.
    
    <hr style="margin: 0px;">
    
    **Attribute:** `exclude`
    
    **Accepted Values:** List of keys

    ???+ example "Example"
        
        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
        ```

??? blank "`addons` - Used to define how multiple keys can be combined under a parent key.<a class="headerlink" href="#addons" title="Permanent link">¶</a>"

    <div id="addons" />Used to define how multiple `dynamic keys` can be combined under a parent key.

    You can define custom parent keys under addons by just using the a key that doesnt exist; it will be considered a 
    custom key combining all keys into one key.

    <hr style="margin: 0px;">
    
    **Attribute:** `addons`
    
    **Accepted Values:** [Dictionary](../pmm/yaml.md#dictionaries) where the key is the `dynamic key` and the value is a
    list of `dynamic keys` to combine.

    ???+ example "Example"
        
        In this example the attribute is used to merge "MTV2", "MTV3" and "MTV (UK)" into the "MTV" collection.
        
        ```yaml
        dynamic_collections:
          networks:
            type: network
            addons:
              MTV:
                - MTV2
                - MTV3
                - MTV (UK)
        ```

??? blank "`template` - Used to define which templates are used.<a class="headerlink" href="#template" title="Permanent link">¶</a>"

    <div id="template" />Used to define which templates are used for these dynamic collections. Each dynamic collection 
    `type` has its own default template, but if you want to define and use your own template you can.

    Each template is passed a few template variables you can use.

    * `value`: The list of keys and addons

    * `key`: The dynamic key

    * `key_name`: The key after `key_name_override`, `remove_prefix`, or `remove_suffix` are run on it.

    <hr style="margin: 0px;">
    
    **Attribute:** `template`
    
    **Accepted Values:** Name of template or list of templates to use 

    ???+ example "Example"

        In this example the template removes the limit on the `smart_filter` so it shows all items in each network.

        Press the :fontawesome-solid-circle-plus: icon to learn more
        
        ```yaml
        templates:
          network collection: #(1)!
            smart_filter:
              sort_by: critic_rating.desc
              all:
                network: <<value>>
        dynamic_collections:
          Networks: #(2)!
            type: network
            title_format: <<key_name>>
            template: network collection #(3)!
        ```
        
        1. This is the mapping name of the template.
        2. This is the mapping name of the Dynamic Collection Definition.
        3. This must match the mapping name of the template you want to use.

??? blank "`template_variables` - Used to define template variables by key.<a class="headerlink" href="#template-variables" title="Permanent link">¶</a>"

    <div id="template-variables" />Used to define template variables by key. This attribute will allow multiple template
    variables to be set per dynamic key. 

    ???+ tip

        You can set a default value for a variable by using `default` instead of the dynamic key. 

    <hr style="margin: 0px;">
    
    **Attribute:** `template_variables`
    
    **Accepted Values:** [Dictionary](../pmm/yaml.md#dictionaries) where the key is the template variable and the value 
    is another [Dictionary](../pmm/yaml.md#dictionaries) where the key is the `dynamic key` of the collection you want 
    change the template variable for and the value is the new value for the template variable.

    ???+ example "Example"

        For example, when using `type: tmdb_collection` and you want to define a poster url for some collections.
        
        ```yaml
        templates:
          my_template:
            optional:
              - my_collection_poster
            tmdb_collection_details: <<value>>
            collection_order: release
            url_poster: <<my_collection_poster>>
        dynamic_collections:
          TMDb Collections:          # This name is the mapping name
            type: tmdb_collection
            remove_suffix: "Collection"
            template: my_template
            template_variables: #(1)!
              my_collection_poster: #(2)!
                119: https://www.themoviedb.org/t/p/original/oENY593nKRVL2PnxXsMtlh8izb4.jpg #(3)!
                531241: https://www.themoviedb.org/t/p/original/nogV4th2P5QWYvQIMiWHj4CFLU9.jpg #(4)!
        ```

        1. Template variables are placed under `template_variables`.
        2. `my_collection_poster` is the template variable being changed.
        3. For key `119` use the url as the my_collection_poster template variable.
        4. For key `531241` use the url as the my_collection_poster template variable.

??? blank "`remove_suffix` - Used to remove the defined suffixes.<a class="headerlink" href="#remove-suffix" title="Permanent link">¶</a>"

    **Attribute:** `remove_suffix`
    
    **Accepted Values:** List or comma-separated string of suffixes to remove

    ???+ example "Example"

        When using `type: tmdb_collection` you may not want every collection title to end with `Collection`.

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

    <div id="title-format" />Used to specify the format you want the collection titles to be.

    There are a few special tags you can include in the `title_format`:

    * `<<key_name>>` is **required** and is what will be replaced by the dynamic key name.

    * `<<limit>>` will be replaced the limit template variable if passed to the definition.

    * `<<library_type>>` will be replaced with either `movie`, `show`, `artist`, or `video` depending on your library 
    type.

    * `<<library_typeU>>` will be replaced with either `Movie`, `Show`, `Artist`, or `Video` depending on your library

    **Accepted Values:** [Dictionary](../pmm/yaml.md#dictionaries) where the key is the key name you want to change and 
    the value is what to change that key name to. 

    ???+ example "Example"

        This example uses `key_name_override` 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
