How to write this better? Ruby Sequel chaining OR -

-

in sql should this:

select * `categories_description_old` ((`categories_description` = '') or (`categories_name` = '') or (`categories_heading_title` = ''))

my (ugly) solution:

conditions = [:categories_name, :categories_heading_title, :categories_description] b = table_categories_description_old.filter(conditions.pop => "") conditions.each |m|  b = b.or(m => "") end

is there better solution chain or conditions?

you can like:

conditions.inject(table_categories_description_old.filter(true)){|acc, cond|   acc.or(cond => '') }

but in cases when have thought out sql query, find easier type whole condition , use sequel sanitize query parameters.
