Hi,
I achieved it using the filter custom condition method and replacing the column.field with the CONCAT function of the fields.
def filter_fullname_condition
->(_column, value) { ::Arel::Nodes::SqlLiteral.new("CONCAT(first_name, ' ', last_name)").matches("#{value}%") }
end
The full code looks like this:
class UsersDatatable < AjaxDatatablesRails::ActiveRecord
def view_columns
@view_columns ||= {
id: { source: 'User.id', cond: :eq },
first_name: { source: 'User.first_name', searchable: false },
last_name: { source: 'User.last_name', searchable: false },
fullname: { source: 'fullname', cond: filter_fullname_condition, searchable: true, orderable: true }
}
end
def data
records.map do |record|
{
id: record.id,
created_at: record.created_at.strftime('%m/%d/%Y'),
fullname: record.fullname,
DT_RowId: record.id
}
end
end
def get_raw_records
User.select("id, first_name, last_name, CONCAT(first_name, ' ', last_name) as fullname").limit(100)
end
def filter_fullname_condition
->(_column, value) { ::Arel::Nodes::SqlLiteral.new("CONCAT(first_name, ' ', last_name)").matches("#{value}%") }
end
end
I suggest you check the SQL generated code and validate the results.
SELECT "users"."id", "users"."first_name", "users"."last_name", concat("users"."first_name", ' ', "users"."last_name") AS fullname
FROM "users"
WHERE (CAST("users"."id" AS VARCHAR) ILIKE '' OR CONCAT(first_name, ' ', last_name) ILIKE 'Cold%')
ORDER BY users.created_at DESC
LIMIT 100 OFFSET 0
Hi. Let's say i have model
User(id, first_name, last_name)
and an instance method calledfull_name
Indata
method I can use record.full_name in order to combinefirst_name
andlast_name
. But I get a problem when trying sort and search on this column. Is there any way to let me do that?
