私は作成には役に立たない都市で新しい学校を作るためのフォームがあります。 city_pathの場合、定義されていないパラメータ:idのエラーが返されます。フォームを提出した後に必要なキーがありません
<% if controller.action_name == "edit" %>
<% if @school.errors.any? %>
<div class="errors alert alert-danger">
<ul>
<% @school.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<%= form_for @school, url: school_path(@school) do |f| %>
<%= f.label "Ime:" %>
<%= f.text_field :name, class: "form-control input-field" %>
<%= f.label "URL slike:" %>
<%= f.text_field :icon_url, class: "form-control input-field" %>
<%= link_to school_path(@school), class: "btn btn-default", "data-no-turbolink": true do %>
<i class="fa fa-chevron-left"></i> Nazad
<% end %>
<%= button_tag(type: "submit", class: "btn btn-default") do %>
<i class="fa fa-check"></i> Pošalji
<% end %>
<% end %>
<% else %>
<% if @school.errors.any? %>
<div class="errors">
<ul>
<% @school.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<%= form_for @school, url: city_schools_path do |f| %>
<%= f.label "Ime:" %>
<%= f.text_field :name, class: "form-control input-field" %>
<%= f.label "URL slike:" %>
<%= f.text_field :icon_url, class: "form-control input-field" %>
<%= link_to city_path(@city), class: "btn btn-default", "data-no-turbolink": true do %>
<i class="fa fa-chevron-left"></i> Nazad
<% end %>
<%= button_tag(type: "submit", class: "btn btn-default") do %>
<i class="fa fa-check"></i> Pošalji
<% end %>
<% end %>
<% end %>
私はこのエラーを取得するフォーム送信しようとすると：
class CitiesController < ApplicationController
def index
@cities = City.all
end
def show
find_city
@schools = @city.schools.all
end
def new
@city = City.new
end
def edit
find_city
end
def update
find_city
if @city.update(city_params)
redirect_to city_path(@city)
else
render "edit"
end
end
def create
@city = City.new(city_params)
if @city.save
redirect_to index_path
else
render "new"
end
end
private
def find_city
@city = City.find(params[:id])
end
def find_schools
@schools = @city.schools.all
end
def city_params
params.require(:city).permit(:name, :icon_url)
end
end
そして、これがschool_controllerです：
No route matches {:action=>"show", :controller=>"cities", :id=>nil} missing required keys: [:id]
をこれは私のcity_controllerある
class SchoolsController < ApplicationController
def index
find_city
@schools = @city.schools.all
end
def new
find_city
@school = @city.schools.new
end
def create
find_city
@school = @city.schools.new(school_params)
if @school.save
redirect_to school_path(@city, @school)
else
render "new"
end
end
def show
find_school
@search = @school.users.ransack(params[:q])
@city = @school.city
if (params.has_key?(:q))
@users = @search.result
else
# Prikazivanje svih korisnika koji su iste generacije kao i
# poslednji dodati korisnik
#@users = @school.users.where(generation: User.last.generation).order("sclass ASC")
#@sclasses = @school.sclasses.where(generation: Sclass.last.generation).order("name ASC")
if Sclass.last.nil?
@sclasses = @school.sclasses.all
else
@sclasses = @school.sclasses.where(generation: Sclass.last.generation).order("name ASC")
end
end
end
def edit
find_school
end
def update
find_school
if @school.update(school_params)
redirect_to school_path(@school)
else
render "edit"
end
end
def destroy
find_city
find_school
@school.destroy
redirect_to city_path(@city)
end
private
def find_city
@city = City.find(params[:city_id])
end
def find_school
@school = School.find(params[:id])
end
def school_params
params.require(:school).permit(:name, :icon_url)
end
end
