employees HABTM projects, projects HABTM employees. I am doing a permissions page for a selected project. I know that I can get all of the employees in the system (@employee.find(:all)) or get all the employees for the selected project. What i''m trying to do is get a list of all the employees in the system and have a check box that states if they are associated with the current project or not. Any ideas please, i''m not asking for code really just a theory of how you would possible go about it. -- Posted via http://www.ruby-forum.com/.

I also need the rest of the employees that are not associated. Both displayed in a list ordered by name with non repeated. The check-box would indicate if the employee was associated with the project or not. By checking the box that would then add the employee to the project. -- Posted via http://www.ruby-forum.com/.
Maybe something like this: all_employees = Employee.find_all # to find all employees in the system in an array project_employees = Project.find(id).employees # to find all employees related to this project in an array other_employees = all_employees - project_employees # a list of employees not in the project Not sure if this is what you want though :) James Whittaker wrote:> employees HABTM projects, projects HABTM employees. > > I am doing a permissions page for a selected project.

I just wanted to be able to have a list off all the employees ordered by name ASC. Each employee would have a checkbox after there name. That check box would be checked if they had an association to the current project. If they did not then the checkbox would be unchecked. Checking the box (or unchecking ) would the add or remove the association to that project. -- Posted via http://www.ruby-forum.com/.
Just at the top of my head, I think it would be simpler if you add a
method in your employee model that determines if the employee is related
to the project or not:
def associated_with_project?(project)
if self.projects.contains? project then
return true
else
return false
end
end
I suppose this can be done in a cleverer way somehow but this should work :)

All this MVC i''m still learning. However taking what you have here I get an error of: undefined method `contains?'' for Project:Class I cannot seem to find the contains? method in the API reference anywhere.Is it a ruby method? Googling contains? reveals nothing. -- Posted via http://www.ruby-forum.com/.
Found that using rubys include? method seems to provisionaly work. Just
need to add the checkbox''s in and do a full test.
def associated_with_project?(project)
if self.projects.include? project then
true
else
false
end
end
