NAME

Catmandu::Fix::add_to_store - add matching values to a store as a side effect

SYNOPSIS

   # Add the current record to an SQLLite database. 
   add_to_store(., DBI, data_source: "dbi:SQLite:path/data.sqlite")

   # Add the journal field to a MongoDB database. 
   add_to_store(journal, MongoDB, database_name: catalog)
   
   # Add all author values to a MongoDB database. 
   add_to_store(authors.*, MongoDB, database_name: catalog, bag: authors)

DESCRIPTION

add_to_store(PATH,STORE[,store_param: store_val, ...][,bag: bag_name])

Store a record or parts of a record in a Catmandu::Store. The values at the PATH will be stored as-is in the database but should be hashes. If the value contains an '_id' field, then it will used as record identifier in the database. If not, then a new '_id' field will be generated and added to the database and original field (for later reference).

For instance this YAML input:

    ---
    _id: 001
    title: test
    name: foo
    ---
    _id: 002
    title: test2
    name: bar

with the fix:

    add_to_store(., DBI, data_source: "dbi:SQLite:path/data.sqlite")

will create a path/data.sqlite SQLite database with two records. Each records contains the _id from the input file and all the record fields.

For instance this YAML input:

    ---
    title: test
    name: foo
    ---
    title: test2
    name: bar

with the fix:

    add_to_store(., DBI, data_source: "dbi:SQLite:path/data.sqlite")

will create a path/data.sqlite SQLite database with two records. Each records contains the a generated _id and all the record fields. The current input stream will be updated to contain the generated _id.

Use Catmandu::Fix::lookup_in_store to lookup records in a Catmandu::Store based on an '_id' key.
