Question

I currently have a table that is listed as follows:

projects = Project.find(:all, :conditions => [conditions + "AND (name LIKE ? OR description LIKE ?)", "%#{params[:query]}%", "%#{params[:query]}%"])

where

 conditions = Project.in_used_projects(:alias => "projects")

However I need to include a 3rd variable which is not from the Project table but from a Tags table. The column I need is Tag - > Names. Is there anyway I can bind variables from another table in Ruby? The Project.find(all) automatically passes the SELECT * FROM Project into MYSQL. Someone has suggested using a join function, but I’m not sure how this would work. Any ideas?

EDIT 1

I have tried the suggested answer of using

projects = Project.find(:all, :joins => "tags", :conditions => [conditions + "AND (projects.name LIKE ? OR description LIKE ? OR tags.name LIKE ?", ["%#{params[:query]}%" * 3]].flatten)

but now I am getting another error

Mysql::Error: Unknown table 'projects': SELECTprojects.* FROMprojectstags WHERE ((projects.status = 2)AND (projects.name LIKE '%%' OR projects.description LIKE '%%' OR tags.name LIKE '%%')

Very strange considering the projects table exists. Why isn’t Ruby recognizing it now that i’ve included another table?

Answer 1

Turns out that it was just a simple syntax error

projects = Project.find(:all, :joins=>:tags, :conditions => [conditions + "AN    rojects.name LIKE ? OR projects.description LIKE ? OR tags.name LIKE ?)", "%#    ams[:query]}%", "%#{params[:query]}%", "%#{params[:query]}%"])

is the correct syntax. The :joins needs to be followed by :tags, not by “tags”
Thanks again for everyone’s help
