我的應用使用了一些固定嵌套的路由。每次鍛鍊has_many
習題,並且每次練習has_many
結果。在試圖創建一個新的練習,我發現了一個錯誤:Rails沒有路由匹配[POST]「/ Exercises/new」
No route matches [POST] "/exercises/new"
這是我workouts#show
頁面上的部分,所有的魔法發生:
<%= render 'exercises/form', exercise: Exercise.new, workout: @workout %>
這裏是exercises/_form.html.erb
部分:
<%= form_for [workout, exercise] do |f| %>
...(form stuff)...
<div class="text-center"><%= f.submit "Create Exercise", class: 'btn btn-primary' %></div>
<% end %>
這裏是我的exercises#controller
:
class ExercisesController < ApplicationController
before_action :require_sign_in
before_action :authorize_user, only: [:destroy, :create]
def index
@exercises = Exercise.all
end
def new
@exercise = Exercise.new
end
def create
@workout = Workout.find(params[:workout_id])
exercise = @workout.exercises.new(exercise_params)
exercise.user = current_user
if exercise.save
flash[:notice] = "Results saved successfully."
redirect_to [@workout]
else
flash[:alert] = "Results failed to save."
redirect_to [@workout]
end
end
def destroy
@workout = Workout.find(params[:post_id])
exercise = @workout.exercise.find(params[:id])
if comment.destroy
flash[:notice] = "Exercise was deleted successfully."
redirect_to [@workout]
else
flash[:alert] = "Exercise couldn't be deleted. Try again."
redirect_to [@workout]
end
end
private
def exercise_params
params.require(:exercise).permit(:name, :seconds, :weight, :reps)
end
def authorize_user
exercise = Exercise.find(params[:id])
unless current_user == current_user.admin?
flash[:alert] = "You do not have permission to create or delete an exercise."
redirect_to [exercise.workout]
end
end
end
這裏是我的路線:
workout_exercise_reports POST /workouts/:workout_id/exercises/:exercise_id/reports(.:format) reports#create
workout_exercise_report DELETE /workouts/:workout_id/exercises/:exercise_id/reports/:id(.:format) reports#destroy
workout_exercises GET /workouts/:workout_id/exercises(.:format) exercises#index
POST /workouts/:workout_id/exercises(.:format) exercises#create
new_workout_exercise GET /workouts/:workout_id/exercises/new(.:format) exercises#new
edit_workout_exercise GET /workouts/:workout_id/exercises/:id/edit(.:format) exercises#edit
workout_exercise GET /workouts/:workout_id/exercises/:id(.:format) exercises#show
PATCH /workouts/:workout_id/exercises/:id(.:format) exercises#update
PUT /workouts/:workout_id/exercises/:id(.:format) exercises#update
DELETE /workouts/:workout_id/exercises/:id(.:format) exercises#destroy
workouts GET /workouts(.:format) workouts#index
POST /workouts(.:format) workouts#create
new_workout GET /workouts/new(.:format) workouts#new
edit_workout GET /workouts/:id/edit(.:format) workouts#edit
workout GET /workouts/:id(.:format) workouts#show
PATCH /workouts/:id(.:format) workouts#update
PUT /workouts/:id(.:format) workouts#update
DELETE /workouts/:id(.:format) workouts#destroy
這來源於此routes.rb
結構:
resources :workouts do
resources :exercises do
resources :reports
end
end
我歡迎任何智慧的人可以擺脫的情況,包括如何修正這個錯誤(主要),但如果有更好的方式來構建我的路線。
附加信息

它顯示錯誤的哪一行? – uday
沒有線,它只是顯示我的路線... – Liz
在你的應用程序中沒有路線'[POST]「/ Exercises/new」'。你的路線中有'[GET]'。 –
