Applies preloads to a query or or post-loads to object(s) with the specified options. See activity_preloads/3 for what preload options you can specify.

Examples

> activity_preloads(query, preload: [])

Applies preloads to a query or or post-loads to object(s) with the specified preloads and options.

Examples

# Object or query with extra assocs preloads

> activity_preloads(object_or_query, [:feed, :with_reply_to, :with_media, :with_object_more, :maybe_with_labelled])
# Object or query several extra assoc preloads

Other possible preloads:

:default

Processes and structures activity data within a media.

Examples

iex> %{id: 1, activity: %{id: 2}} = activity_under_media(%{activity: %Bonfire.Data.Social.Activity{id: 2, media: %{id: 1}}})

Processes and structures activity data within an object.

Examples

iex> %{id: 1, activity: %{id: 2}} = activity_under_object(%{activity: %Bonfire.Data.Social.Activity{id: 2, object: %{id: 1}}})

Outputs the names of all object verbs for localization, for the purpose of adding to the localisation strings, as long as the output is piped through to localise_strings/1 at compile time.

Retrieves additional verb names with various formats for localization.

Filters a query to include only permitted objects.

Examples

> as_permitted_for(query, [])
# Filtered query

Casts a changeset with the provided verb, creator and options.

Examples

> cast(changeset, :like, %User{}, feed_ids: [])
# Changeset with associations set

Counts the total number of activities.

Create an Activity. NOTE: you will usually want to use cast/3 instead or maybe Objects.publish/5

Examples

> create(%User{id: "1"}, :like, %Post{id: "1"})
{:ok, %Activity{}}

Deletes activities by ID or struct, or using specific filters.

Examples

> delete(activity)
# Number of deleted activities

> delete("1")
# Number of deleted activities

> delete([id: "1"])
# Number of deleted activities

Deletes an activity by object ID.

Examples

> delete_by_object("1")
# Number of deleted objects

Deletes an activity by subject, verb, and object.

Examples

> delete_by_subject_verb_object(%User{id: "1"}, :like, %Post{id: "1"})
# Number of deleted activities

Retrieves the cursor value for pagination based on field or data structure.

Examples

> fetch_cursor_value_fun(%{nested_replies_count: 5}, :num_replies)
# returns the cursor value based on the number of replies

Gets an activity by its ID.

Examples

> get("activity_id", [])

Loads an object based on its ID or pointer.

Examples

> load_object("object_id")

Optionally joins the creator.

Performs a query optimization: only includes the creator if different from the subject or current user.

If skip_loading_user_ids is empty, the creator is always included. Otherwise, it is included only if it is different from the users in skip_loading_user_ids.

Examples

> maybe_join_creator(query, [])
# returns query with creator preloaded if different from the subject

> maybe_join_creator(query, [1, 2, 3])
# returns query with creator included only if creator.id not in [1, 2, 3]

Optimizes the query to optionally include the subject data.

If skip_loading_user_ids is empty, the subject is always included. Otherwise, it is included only if it is different from the users in skip_loading_user_ids.

Examples

> maybe_join_subject(query, [])
# returns query with subject preloaded

> maybe_join_subject(query, [1, 2, 3])
# returns query with subject included only if subject.id not in [1, 2, 3]

Retrieves or constructs the object from an activity.

Examples

iex> object_from_activity(%{object: %{id: 1}})
%{id: 1}

Preloads the activity for an object and verb.

Examples

> object_preload_activity(%Post{}, :like)
# Object with preloaded activity

Preloads the creation activity for an object.

Examples

> object_preload_create_activity(%Post{})
# Object with preloaded creation activity

Provides cursor fields for ordering based on sort criteria.

Examples

> order_cursor_fields(:num_likes, :asc)
# returns cursor fields for ordering by number of likes in ascending order

Provides pagination options for ordering.

Examples

> order_pagination_opts(:num_likes, :desc)
# returns pagination options for ordering by number of likes in descending order

Constructs a query based on filters and optional user context.

Examples

> query(filters)

iex> query([my: :feed], [current_user: nil])

Callback implementation for Bonfire.Common.ContextModule.query_module/0.

Preloads activity for objects in a query using the specified verb and object ID field.

Examples

> query_object_preload_activity(query, :like, :post_id, [])
# Query with preloaded activities

Preloads creation activity for objects in a query.

Examples

> query_object_preload_create_activity(query, [])

Orders query results based on a specified field and sort order.

Examples

> query_order(query, :num_replies, :asc)
# returns the query ordered by number of replies in ascending order

Retrieves an activity based on a query and options.

Examples

> read(query)
# returns an activity based on the provided query

> read(object_id)
# returns an activity for the provided object ID (usually a create activity)

Constructs a query for reading activities based on input.

Examples

> read_query(query, opts)

Callback implementation for Bonfire.Common.ContextModule.schema_module/0.

Returns a localized and formatted display name for a verb.

Examples

iex> verb_display("create")

Retrieves or constructs an ID for a verb based on its name or identifier.

Examples

iex> verb_id(:create)

Optionally modifies the verb based on activity context.

Examples

iex> verb_maybe_modify("Create", %{object: %{post_content: %{id: 1}}})
"Write"

Returns the name of a verb based on its slug or identifier.
