Rails - how to search based on a boolean field? (MySQL error)

Question

I'm running the following query

@projects = @company.projects.where("active = ?", true).order("created_at ASC")

and I'm getting the error:

`ActiveRecord::StatementInvalid: Mysql::ParseError: You have an error in your SQL...`

the error points to the = '1' .

I've tried many variations on my query but I cannot figure out the problem. How can I solve this?

Answer 1

Try:

@projects = @company.projects.where(:active =>  true)

(it also works with strings 'active').

You can also look at http://guides.rubyonrails.org/active_record_querying.html#hash-conditions for more details.

There is also a nice railscast about this which explains why you might have problems (I'm not allowed to post 2 links so you should search for it :) )

Answer 2

您不需要对文字使用参数化查询，只需执行以下操作：

@projects = @company.projects.where("active = 1").order("created_at ASC")
