ruby on rails - Implicit routing for nested controllers with same namespace -


given rails 4.1, 2 controllers crm::companiescontroller , crm::contactpeople, 2 models crm::company , crm::contactperson , following routes:

namespace :crm   resources :companies     resources :contact_people   end end

the generated url helpers contain crm namespace once, want:

crm_company_contact_people       /crm/companies/:company_id/contact_people(.:format) new_crm_company_contact_person   /crm/companies/:company_id/contact_people/new(.:format)  # ...

however, using array approach url helpers

= form_for([@crm_company, @crm_contact_person]) |f|

tries generate url each resource namespaced:

undefined method `crm_company_crm_contact_people_path' #<#<class...

i have "crm" in paths once @ beginning (unless breaks common rails approach) , ugly add url each form explicitly. there can (perhaps in routes, model or first form_for argument) rails knows how build correct path? or there more rails-like way generate kind of structure rails knows automatically how build paths?

you need include namespace in call form_for:

= form_for([:crm, @crm_company, @crm_contact_person]) |f|

also, since you're using namespaced models, need define following class method on them (from rails/rails issue #10705) ignore namespace:

def self.use_relative_model_naming?   true end
