ROR: Nested Resources: NoMethodError

Question

In my application teams are created to solve a challenge. Once the team is created, members can join that team.

Everything works when creating the challenge -> the team, but when it comes to adding the team member that is when I receive this error:

Error

NoMethodError in Team_members#new

Showing /home/vincent/solvabl/app/views/team_members/_form.html.erb where line #1 raised:

undefined method `team_team_members_path' for #<#<Class:0x9bdadcc>:0xa179df0>

Extracted source (around line #1):

Any help is much appreciated!

Answer 1

The routes you have will give you challenges_team_team_members_path. In order to get team_team_members_path add the following to your config/routes.rb:

resources :teams do 
  resources :team_members
end

Update:

Please note that this addition should be in addition to what you've already defined. So, your routes.rb would have:

resources :challenges do
  resources :teams do
    resources :team_members
  end
end

resources :teams do 
  resources :team_members
end
