+# Caching
+
+To improve performance, NetBox supports caching for most object and list views. Caching is implemented using Redis,
+and [django-cacheops](https://github.com/Suor/django-cacheops)
+
+Several management commands are avaliable for administrators to manaully invalidate cache entries in extenuating circumstances.
+
+To invalidate a specifc model instance (for example a Device with ID 34):
+```
+python netbox/manage.py invalidate dcim.Device.34
+```
+
+To invalidate all instance of a model:
+```
+python netbox/manage.py invalidate dcim.Device
+```
+
+To flush the entire cache database:
+```
+python netbox/manage.py invalidate all
+```

docs/additional-features/custom-links.md

+# Custom Links
+
+Custom links allow users to place arbitrary hyperlinks within NetBox views. These are helpful for cross-referencing related records in external systems. For example, you might create a custom link on the device view which links to the current device in a network monitoring system.
+
+Custom links are created under the admin UI. Each link is associated with a particular NetBox object type (site, device, prefix, etc.) and will be displayed on relevant views. Each link is assigned text and a URL, both of which support Jinja2 templating. The text and URL are rendered with the context variable `obj` representing the current object.
+
+For example, you might define a link like this:
+
+* Text: `View NMS`
+* URL: `https://nms.example.com/nodes/?name={{ obj.name }}`
+
+When viewing a device named Router4, this link would render as:
+
+```
+<a href="https://nms.example.com/nodes/?name=Router4">View NMS</a>
+```
+
+Custom links appear as buttons at the top right corner of the page. Numeric weighting can be used to influence the ordering of links.
+
+## Conditional Rendering
+
+Only links which render with non-empty text are included on the page. You can employ conditional Jinja2 logic to control the conditions under which a link gets rendered.
+
+For example, if you only want to display a link for active devices, you could set the link text to
+
+```
+{% if obj.status == 1 %}View NMS{% endif %}
+```
+
+The link will not appear when viewing a device with any status other than "active."
+
+Another example, if you want to only show an object of a certain manufacturer, you could set the link text to:
+
+```
+{% if obj.device_type.manufacturer.name == 'Cisco' %}View NMS {% endif %}
+```
+
+The link will only appear when viewing a device with a manufacturer name of "Cisco."
+
+## Link Groups
+
+You can specify a group name to organize links into related sets. Grouped links will render as a dropdown menu beneath a
+single button bearing the name of the group.

+# Custom Scripts
+
+Custom scripting was introduced to provide a way for users to execute custom logic from within the NetBox UI. Custom scripts enable the user to directly and conveniently manipulate NetBox data in a prescribed fashion. They can be used to accomplish myriad tasks, such as:
+
+* Automatically populate new devices and cables in preparation for a new site deployment
+* Create a range of new reserved prefixes or IP addresses
+* Fetch data from an external source and import it to NetBox
+
+Custom scripts are Python code and exist outside of the official NetBox code base, so they can be updated and changed without interfering with the core NetBox installation. And because they're written from scratch, a custom script can be used to accomplish just about anything.
+
+## Writing Custom Scripts
+
+All custom scripts must inherit from the `extras.scripts.Script` base class. This class provides the functionality necessary to generate forms and log activity.
+
+```
+from extras.scripts import Script
+
+class MyScript(Script):
+    ..
+```
+
+Scripts comprise two core components: variables and a `run()` method. Variables allow your script to accept user input via the NetBox UI. The `run()` method is where your script's execution logic lives. (Note that your script can have as many methods as needed: this is merely the point of invocation for NetBox.)
+
+```
+class MyScript(Script):
+    var1 = StringVar(...)
+    var2 = IntegerVar(...)
+    var3 = ObjectVar(...)
+
+    def run(self, data):
+        ...
+```
+
+The `run()` method is passed a single argument: a dictionary containing all of the variable data passed via the web form. Your script can reference this data during execution.
+
+Defining variables is optional: You may create a script with only a `run()` method if no user input is needed.
+
+Returning output from your script is optional. Any raw output generated by the script will be displayed under the "output" tab in the UI.
+
+## Module Attributes
+
+### `name`
+
+You can define `name` within a script module (the Python file which contains one or more scripts) to set the module name. If `name` is not defined, the filename will be used.
+
+## Script Attributes
+
+Script attributes are defined under a class named `Meta` within the script. These are optional, but encouraged.
+
+### `name`
+
+This is the human-friendly names of your script. If omitted, the class name will be used.
+
+### `description`
+
+A human-friendly description of what your script does.
+
+### `field_order`
+
+A list of field names indicating the order in which the form fields should appear. This is optional, however on Python 3.5 and earlier the fields will appear in random order. (Declarative ordering is preserved on Python 3.6 and above.) For example:
+
+```
+field_order = ['var1', 'var2', 'var3']
+```
+
+## Reading Data from Files
+
+The Script class provides two convenience methods for reading data from files:
+
+* `load_yaml`
+* `load_json`
+
+These two methods will load data in YAML or JSON format, respectively, from files within the local path (i.e. `SCRIPTS_ROOT`).
+
+## Logging
+
+The Script object provides a set of convenient functions for recording messages at different severity levels:
+
+* `log_debug`
+* `log_success`
+* `log_info`
+* `log_warning`
+* `log_failure`
+
+Log messages are returned to the user upon execution of the script. Markdown rendering is supported for log messages.
+
+## Variable Reference
+
+### StringVar
+
+Stores a string of characters (i.e. a line of text). Options include:
+
+* `min_length` - Minimum number of characters
+* `max_length` - Maximum number of characters
+* `regex` - A regular expression against which the provided value must match
+
+Note: `min_length` and `max_length` can be set to the same number to effect a fixed-length field.
+
+### TextVar
+
+Arbitrary text of any length. Renders as multi-line text input field.
+
+### IntegerVar
+
+Stored a numeric integer. Options include:
+
+* `min_value:` - Minimum value
+* `max_value` - Maximum value
+
+### BooleanVar
+
+A true/false flag. This field has no options beyond the defaults.
+
+### ObjectVar
+
+A NetBox object. The list of available objects is defined by the queryset parameter. Each instance of this variable is limited to a single object type.
+
+* `queryset` - A [Django queryset](https://docs.djangoproject.com/en/stable/topics/db/queries/)
+
+### FileVar
+
+An uploaded file. Note that uploaded files are present in memory only for the duration of the script's execution: They will not be save for future use.
+
+### IPNetworkVar
+
+An IPv4 or IPv6 network with a mask.
+
+### Default Options
+
+All variables support the following default options:
+
+* `label` - The name of the form field
+* `description` - A brief description of the field
+* `default` - The field's default value
+* `required` - Indicates whether the field is mandatory (default: true)
+
+## Example
+
+Below is an example script that creates new objects for a planned site. The user is prompted for three variables:
+
+* The name of the new site
+* The device model (a filtered list of defined device types)
+* The number of access switches to create
+
+These variables are presented as a web form to be completed by the user. Once submitted, the script's `run()` method is called to create the appropriate objects.

+# Prometheus Metrics
+
+NetBox supports optionally exposing native Prometheus metrics from the application. [Prometheus](https://prometheus.io/) is a popular time series metric platform used for monitoring.
+
+NetBox exposes metrics at the `/metrics` HTTP endpoint, e.g. `https://netbox.local/metrics`. Metric exposition can be toggled with the `METRICS_ENABLED` configuration setting. Metrics are not exposed by default.
+
+## Metric Types
+
+NetBox makes use of the [django-prometheus](https://github.com/korfuri/django-prometheus) library to export a number of different types of metrics, including:
+
+- Per model insert, update, and delete counters
+- Per view request counters
+- Per view request latency histograms
+- Request body size histograms
+- Response body size histograms
+- Response code counters
+- Database connection, execution, and error counters
+- Cache hit, miss, and invalidation counters
+- Django middleware latency histograms
+- Other Django related metadata metrics
+
+For the exhaustive list of exposed metrics, visit the `/metrics` endpoint on your NetBox instance.
+
+## Multi Processing Notes
+
+When deploying NetBox in a multiprocess mannor--such as using Gunicorn as recomented in the installation docs--the Prometheus client library requires the use of a shared directory
+to collect metrics from all the worker processes. This can be any arbitrary directory to which the processes have read/write access. This directory is then made available by use of the
+`prometheus_multiproc_dir` environment variable.
+
+This can be setup by first creating a shared directory and then adding this line (with the appropriate directory) to the `[program:netbox]` section of the supervisor config file.

Within each application, each model has its own path. For example, the provider and circuit objects are located under the "circuits" application:

-Related objects (e.g. `ForeignKey` fields) are represented using a nested serializer. A nested serializer provides a minimal representation of an object, including only its URL and enough information to construct its name. When performing write api actions (`POST`, `PUT`, and `PATCH`), any `ForeignKey` relationships do not use the nested serializer, instead you will pass just the integer ID of the related model.  
+## Related Objects
 
-When a base serializer includes one or more nested serializers, the hierarchical structure precludes it from being used for write operations. Thus, a flat representation of an object may be provided using a writable serializer. This serializer includes only raw database values and is not typically used for retrieval, except as part of the response to the creation or updating of an object.
+Related objects (e.g. `ForeignKey` fields) are represented using a nested serializer. A nested serializer provides a minimal representation of an object, including only its URL and enough information to display the object to a user. When performing write API actions (`POST`, `PUT`, and `PATCH`), related objects may be specified by either numeric ID (primary key), or by a set of attributes sufficiently unique to return the desired object.

+For example, when creating a new device, its rack can be specified by NetBox ID (PK):
 
 ```
 {
-    "id": 1201,
-    "site": 7,
-    "group": 4,
-    "vid": 102,

+Note that if the provided parameters do not return exactly one object, a validation error is raised.
+
+## Brief Format
+
+Most API endpoints support an optional "brief" format, which returns only a minimal representation of each object in the response. This is useful when you need only a list of the objects themselves without any related data, such as when populating a drop-down list in a form.
+
+For example, the default (complete) format of an IP address looks like this:
+
+```
+GET /api/ipam/prefixes/13980/
+
+{
+    "id": 13980,
+    "family": 4,
+    "prefix": "192.0.2.0/24",

+    },
+    "role": null,
+    "is_pool": false,
+    "description": "",
+    "tags": [],
+    "custom_fields": {},

+    "last_updated": "2018-12-11T16:27:55.073174-05:00"
+}
+```
+
+The brief format is much more terse, but includes a link to the object's full representation:
+
+```
+GET /api/ipam/prefixes/13980/?brief=1
+
+{
+    "id": 13980,
+    "url": "https://netbox/api/ipam/prefixes/13980/",
+    "family": 4,
+    "prefix": "192.0.2.0/24"
+}
+```
+
+The brief format is supported for both lists and individual objects.

 ## Static Choice Fields

+# Extending Models
+
+Below is a list of items to consider when adding a new field to a model:
+
+### 1. Generate and run database migration
+
+Django migrations are used to express changes to the database schema. In most cases, Django can generate these automatically, however very complex changes may require manual intervention. Always remember to specify a short but descriptive name when generating a new migration.
+
+```
+./manage.py makemigrations <app> -n <name>
+./manage.py migrate
+```
+
+Where possible, try to merge related changes into a single migration. For example, if three new fields are being added to different models within an app, these can be expressed in the same migration. You can merge a new migration with an existing one by combining their `operations` lists.
+
+!!! note
+    Migrations can only be merged within a release. Once a new release has been published, its migrations cannot be altered.
+
+### 2. Add validation logic to `clean()`
+
+If the new field introduces additional validation requirements (beyond what's included with the field itself), implement them in the model's `clean()` method. Remember to call the model's original method using `super()` before or agter your custom validation as appropriate:
+
+```
+class Foo(models.Model):
+
+    def clean(self):
+
+        super(DeviceCSVForm, self).clean()
+
+        # Custom validation goes here
+        if self.bar is None:
+            raise ValidationError()
+```
+
+### 3. Add CSV helpers
+
+Add the name of the new field to `csv_headers` and included a CSV-friendly representation of its data in the model's `to_csv()` method. These will be used when exporting objects in CSV format.
+
+### 4. Update relevant querysets
+
+If you're adding a relational field (e.g. `ForeignKey`) and intend to include the data when retreiving a list of objects, be sure to include the field using `prefetch_related()` as appropriate. This will optimize the view and avoid excessive database lookups.
+
+### 5. Update API serializer
+
+Extend the model's API serializer in `<app>.api.serializers` to include the new field. In most cases, it will not be necessary to also extend the nested serializer, which produces a minimal represenation of the model.
+
+### 6. Add choices to API view
+
+If the new field has static choices, add it to the `FieldChoicesViewSet` for the app.
+
+### 7. Add field to forms
+
+Extend any forms to include the new field as appropriate. Common forms include:
+
+* **Credit/edit** - Manipulating a single object
+* **Bulk edit** - Performing a change on mnay objects at once
+* **CSV import** - The form used when bulk importing objects in CSV format
+* **Filter** - Displays the options available for filtering a list of objects (both UI and API)
+
+### 8. Extend object filter set
+
+If the new field should be filterable, add it to the `FilterSet` for the model. If the field should be searchable, remember to reference it in the FilterSet's `search()` method.
+
+### 9. Add column to object table
+
+If the new field will be included in the object list view, add a column to the model's table. For simple fields, adding the field name to `Meta.fields` will be sufficient. More complex fields may require explicitly declaring a new column.
+
+### 10. Update the UI templates
+
+Edit the object's view template to display the new field. There may also be a custom add/edit form template that needs to be updated.
+
+### 11. Adjust API and model tests
+
+Extend the model and/or API tests to verify that the new field and any accompanying validation logic perform as expected. This is especially important for relational fields.

A git commit hook is provided in the source at `scripts/git-hooks/pre-commit`. Linking to this script from `.git/hooks/` will invoke `pycodestyle` prior to every commit attempt and abort if the validation fails.
+
+```
+$ cd .git/hooks/
+$ ln -s ../../scripts/git-hooks/pre-commit
+```
+
+To invoke `pycodestyle` manually, run:
+
+```
+pycodestyle --ignore=W504,E501 netbox/
+```
+
+## Introducing New Dependencies
+
+The introduction of a new dependency is best avoided unless it is absolutely necessary. For small features, it's generally preferable to replicate functionality within the NetBox code base rather than to introduce reliance on an external project. This reduces both the burden of tracking new releases and our exposure to outside bugs and attacks.
+
+If there's a strong case for introducing a new depdency, it must meet the following criteria:
+
+* Its complete source code must be published and freely accessible without registration.
+* Its license must be conducive to inclusion in an open source project.
+* It must be actively maintained, with no longer than one year between releases.
+* It must be available via the [Python Package Index](https://pypi.org/) (PyPI).
+
+When adding a new dependency, a short description of the package and the URL of its code repository must be added to `base_requirements.txt`. Additionally, a line specifying the package name pinned to the current stable release must be added to `requirements.txt`. This ensures that NetBox will install only the known-good release and simplify support efforts.
+
+## General Guidance
+
+* When in doubt, remain consistent: It is better to be consistently incorrect than inconsistently correct. If you notice in the course of unrelated work a pattern that should be corrected, continue to follow the pattern for now and open a bug so that the entire code base can be evaluated at a later point.
+
+* No easter eggs. While they can be fun, NetBox must be considered as a business-critical tool. The potential, however minor, for introducing a bug caused by unnecessary logic is best avoided entirely.
+
+* Constants (variables which generally do not change) should be declared in `constants.py` within each app. Wildcard imports from the file are acceptable.
+
+* Every model should have a docstring. Every custom method should include an expalantion of its function.
+
+* Nested API serializers generate minimal representations of an object. These are stored separately from the primary serializers to avoid circular dependencies. Always import nested serializers from other apps directly. For example, from within the DCIM app you would write `from ipam.api.nested_serializers import NestedIPAddressSerializer`.
