# Set params for column search. This is class method so you do not need
# datatable instance.
#
# @example
# link_to 'Published posts for my@email.com',
# posts_path(PostsDatatable.params('posts.status': :published,
# 'users.email: 'my@email.com')
#
# You can always use your params for filtering outside of datatable and
# merge to params
# @example
# link_to 'Published posts for user1',
# posts_path(PostsDatatable.param_set('posts.status', :published).merge(user_id: user1.id))

# form_tag url: posts_path, method: :get do |f|
# f.text_field PostsDatatable.form_field_name('users.email'), 'my@email.com'
# # it is the same as
# f.text_field 'columns[3][search][value]', 'my@email.com'
