To define what to export, to where and how, we’re using a
.gitify file formatted in YAML. This file is located in the root of the project.
As of Gitify v2.0.1-pl, it’s possible to specify a different YAML config file to use with the
--dotfile option, when used with the
gitify extract --dotfile=.myconfigfile
.gitify may look like this:
data_directory: _data/ backup_directory: _backup/ data: contexts: class: modContext primary: key context_settings: class: modContextSetting primary: - context_key - key content: type: content exclude_keys: - editedby - editedon categories: class: modCategory primary: category truncate_on_force: - modCategoryClosure templates: class: modTemplate primary: templatename extension: .html template_variables: class: modTemplateVar primary: name template_variables_access: class: modTemplateVarTemplate primary: - tmplvarid - templateid chunks: class: modChunk primary: name extension: .html snippets: class: modSnippet primary: name extension: .php plugins: class: modPlugin primary: name extension: .php plugin_events: class: modPluginEvent primary: - pluginid - event events: class: modEvent primary: name namespaces: class: modNamespace primary: name system_settings: class: modSystemSetting primary: key where: - 'editedon:!=': '0000-00-00 00:00:00' exclude_keys: - editedon extension_packages: class: modExtensionPackage primary: namespace exclude_keys: - created_at - updated_at fc_sets: class: modFormCustomizationSet primary: id fc_profiles: class: modFormCustomizationProfile primary: id fc_profile_usergroups: class: modFormCustomizationProfileUserGroup primary: - usergroup - profile fc_action_dom: class: modActionDom primary: - set - name mediasources: class: modMediaSource primary: id mediasource_elements: class: sources.modMediaSourceElement primary: - source - object_class - object - context_key dashboards: class: modDashboard primary: - id - name dashboard_widgets: class: modDashboardWidget primary: id dashboard_widget_placement: class: modDashboardWidgetPlacement primary: - dashboard - widget
.gitify file structure is real simple. There are root nodes for
data_directory (the relative path where to store the files),
data contains an array of what we call “Partitions”. These partitions are basically the name of the directory that holds all the files of that type, and can also be used in the
Gitify extract and
Gitify build commands. Each partition specifies either a
type that has special processing going on (only
content is available as type currently), or a
class which specified the xPDOObject derivative that you want to use. The
primary field determines the key to use in the name of the generated files. This defaults to
id, but in many cases you may want to use the
name as that is more human friendly. The primary is used for the file names and is also related to the automatic ID conflict resolution.
By default files will be created with a
.yaml extension, but if you want you can override that with a
extension property. This can help with syntax highlighting in IDEs.
Each partition can also specify a
where property. This contains an array which can be turned into a valid xPDO criteria.
When using GitifyWatch, there is also an
environments root node in the gitify file, refer to the GitifyWatch documentation for more about that.
Third party packages (models)
When a certain class is not part of the core models, you can define a
package as well. This will run
$modx->addPackage before attempting to load the data. The path is determined by looking at a
[package].core_path setting suffixed with
[[++core_path]]components/[package]/model/or a hardcoded
package_path property. For example, you could use the following in your
.gitify file to load ContentBlocks Layouts & Fields:
data: cb_fields: class: cbField primary: name package: contentblocks cb_layouts: class: cbLayout primary: name
As it’ll load the package into memory, it’s only required to add the package once. For clarify, it can’t hurt to add it to each
data entry that uses it.
Dealing with Closures
A Closure is a separate table in the database that a core or third party extra may use to keep information about a hierarchy in a convenient format. These are often automatically generated when creating a new object, which can result in a error messages and other issues when building, especially with the
To solve this, a
truncate_on_force option was introduced in v0.6.0 that lets you define an array of class names that need their tables truncated on a force build. Truncating the closure table(s) before a forced build ensures that the model can properly create the rows in the closure table, without throwing errors.
Here are two examples of using
data: categories: class: modCategory primary: category truncate_on_force: - modCategoryClosure quip_comments: class: quipComment package: quip primary: [thread, id] truncate_on_force: - quipCommentClosure
Composite Primary Keys
When an object doesn’t have a single primary key, or you want to get fancy with file names, it’s possible to define a composite primary key, by setting the
primary attribute to an array. For example, like this:
data: chunks: class: modChunk primary: [category, name] extension: .html
That would grab the category and the name as primary keys, and join them together with a dot in the file name. This is a pretty bad example, and you shouldn’t really use it like this.
Install MODX Packages
You can also define packages to install with the
Gitify package:install --all command. This uses the following format
packages: modx.com: service_url: http://rest.modx.com/extras/ packages: - ace - wayfinder modmore.com: service_url: https://rest.modmore.com/ credential_file: '.modmore.com.key' packages: - clientconfig
When a provider needs to be authenticated, like modmore.com the example above, you can provide a
credential_file option which points to a file name. This file needs to contain a
api_key value (in YAML format), like so:
username: my_api_key_username api_key: some_api_key_password
Alternatively, you can also define the username and api_key directly on the provider information in the .gitify file, but the credential_file approach is recommended to be able of keeping your authentication outside of the repository.
For security, the key file needs to be kept out of the git repository using a .gitignore file, and you will also want to protect direct read access to it with your .htaccess file or keeping it out of the webroot.
To install the packages that you added to the
packages entry in the .gitify file, simply run the command
Gitify package:install --all. That will attempt to install all packages that were mentioned, skipping any that are already installed.
