Upgrade to Rails 4.2.0: string literals in where conditions wrapped into quotation marks

Question

During an upgrade of rails version in my application from 4.1.8 to 4.2.0 , I have encountered the following issue.

String literals in where conditions are now additionally wrapped into quotation marks, which then become part of a query string, delivering no valid results anymore. This happens only for database fields of a text type ( varchar fields are not affected). I am using a MySQL database.

> Table.where(column: 'data')
[08:19:20.822552] Table Load (0.3ms)  SELECT `table`.* FROM `table`
WHERE `table`.`column` = '\"data\"'

Now, if you have a row containing data value in a column row, this condition will no longer match (obviously, "data" is not a match anymore).

In Rails 4.1.8 everything worked perfectly fine:

 > Table.where(column: 'data')
 [08:19:58.303366] Table Load (0.4ms)  SELECT `table`.* FROM `table`
 WHERE `table`.`column` = 'data'

I don't know if this is a default or a configurable behaviour. I somehow haven't found a corresponding release note on that. I would be very grateful for any suggestions on what has changed and what is the best way to fix it.

Many thanks for help!

Answer 1

Could you try this way:

Table.where("column=?", 'data')

I guess this will work.
