I have a routing error with a nested resource. Here is my nested routing:
resources :users do
resources :pages
end
This is my minitest "visit new user page" system test:
test "visit new user page path" do
user = User.create
visit new_user_page_path(user)
assert_selector "h1", text: "Page"
end
This fails with the following error:
Error:
PagesTest#test_visit_new_user_page_path:
ActionView::Template::Error: undefined method `pages_path' for #<#<Class:0x00007fa0299dfa28>:0x00007fa02aa23df8>
Did you mean? image_path
app/views/pages/_form.html.erb:1:in `_app_views_pages__form_html_erb__3658586168370814469_70162960780560'
app/views/pages/new.html.erb:3:in `_app_views_pages_new_html_erb__3548077654233884011_70162934875400'
I realize that pages_path is not a correct path for this nested resource. The correct path to pages#new is new_user_page_path(#user) (which is the path that took me to new.html.erb). The correct path to pages#create is a POST to user_pages_path(#user) (which is the page that new.html.erb should POST to). But I cannot find anywhere that pages_path is being called. The error says that it is being called in new.html.erb and also _form.html.erb. Here are those pages. First, new.html.erb:
<h1>New Page</h1>
<%= render 'form', page: #page %>
<%= link_to 'Back', user_pages_path(#page) %>
And _form.html.erb:
<%= form_with(model: page, local: true) do |form| %>
<% if page.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(page.errors.count, "error") %> prohibited this page from being saved:</h2>
<ul>
<% page.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= form.label :title %>
<%= form.text_field :title, id: :page_title %>
</div>
<div class="field">
<%= form.label :content %>
<%= form.text_area :content, id: :page_content %>
</div>
<div class="field">
<%= form.label :user_id %>
<%= form.text_field :user_id, id: :page_user_id %>
</div>
<div class="actions">
<%= form.submit %>
</div>
<% end %>
I don't know where pages_path is being called, so I can't fix that error. Any help is appreciated.
You need to change your form code, page_path is called from it. Should be
<%= form_with(model: [ #user, #page ]) do |form| %>
In this case the route will be set correctly.

Good night.
I'm doing the getting started guide of RoR, but I have a trouble:
When I click the New Article button that redirects to the form, Rails throw an 'Encountered a syntax error while rendering template.'
The new.html.erb code is
<h1>New Article</h1>
<%= form_with scope: :article, url: articles_path, local: true do |form| %>
<%= if #article.errors.any? %>
<div id="error_explanation">
<h2>
<%= pluralize(#article.errors.count, "error") %>
prohibited this article from being saved:
</h2>
<ul>
<% #article.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<P>
<%= form.label :title %><br>
<%= form.text_field :title %>
</p>
<p>
<%= form.label :text %><br>
<%= form.text_area :text %>
</p>
<p>
<%= form.submit %>
</p>
<% end %>
<%= link_to 'Back', articles_path %>
The code is the same as the guide's code, so i don't know where the error or errors can be.
I also attach the error screenshot if it's any help.
Rails error message when I want tho create a new Article
Here two problems:
wrong syntax in if condition (don't need to use =)
extra \n chars in your screenshot
Change your 5 line in app/view/articles/new.html.erb to:
<% if #article.errors.any? %>
<% %> executes Ruby code
<%= %> executes Ruby code and prints out
Also read about the difference on SO
I'm working on a project in Ruby on Rails (Ruby v.2.2.8, Rails 5.1.4) and have encountered a very strange issue.
For my show method in the controller, I have:
def show
#county = County.find(params[:id])
end
And it works. For update, I have.
def update
#county = County.find(params[:id])
if #county.update(county_params)
redirect_to #county
else
render 'edit'
end
end
In my 'edit', I consistently get an error that #county is nil. The error page indicates that the parameters are being passed as:
{'id'=>4}
as an example. When I use find_by from the rails console, the item is found.
Is there something here I'm missing?
ETA: View Code
<%= form_with model: #county, local: true do |form| %>
<% if #county.errors.any? %>
<div id="error_explanation">
<h2>
<%= pluralize(#county.errors.count, "error") %> prohibited
this county from being saved:
</h2>
<ul>
<% #county.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<p>
<%= form.label :name %><br>
<%= form.text_field :name %>
</p>
<p>
<%= form.label :shortname %><br>
<%= form.text_field :shortname %>
</p>
<p>
<%= form.submit %>
</p>
<% end %>
ETA Routes for Counties:
counties GET /counties(.:format) counties#index
POST /counties(.:format) counties#create
new_county GET /counties/new(.:format) counties#new
edit_county GET /counties/:id/edit(.:format) counties#edit
county GET /counties/:id(.:format) counties#show
PATCH /counties/:id(.:format) counties#update
PUT /counties/:id(.:format) counties#update
DELETE /counties/:id(.:format) counties#destroy
The error occurs at /counties/:id/edit
How is your edit action in your controller?
You should define #county as well
def edit
#county = County.find(params[:id])
end
I generated a scaffold for a portfolio via the Rails command, rails g portfolio titre:string, thumbnail:string lien:string description:text. I also added FriendlyId to get a better URL, and that's about all. Here is the 'update' action.
def update
if #portfolio.update(portfolio_params)
redirect_to #portfolio, notice: 'Portfolio mis à jour.'
else
render :edit
end
end
However, when trying to update a project in my portfolio, the submit button tries to get to 'portfolio#update' via patch, but puts a '.' instead of a '/' which gives me No route matches [PATCH] "/portfolios.test-1"
For the route, I only have resources :portfolios
edit : added the form
<%= form_for #portfolio, url: portfolios_path(#portfolio) do |f| %>
<% if portfolio.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(portfolio.errors.count, "error") %> prohibited this portfolio from being saved:</h2>
<ul>
<% portfolio.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :titre %>
<%= f.text_field :titre %>
</div>
<div class="field">
<%= f.label :categorie %>
<%= f.text_field :categorie %>
</div>
<div class="field">
<%= f.label :description %>
<%= f.text_area :description %>
</div>
<div class="field">
<%= f.label :thumbnail %>
<%= f.file_field :thumbnail %>
</div>
<div class="field">
<%= f.label :lien %>
<%= f.text_field :lien %>
</div>
<div class="actions">
<%= f.submit 'Enregistrer' %>
</div>
<% end %>
I didn't have any other possibilities that doing #portfolio, url: portfolios_path(#portfolio), otherwise Rails considered that '#portfolio' was nil
edit 2 : added the private 'set_portfolio' params
private
# Use callbacks to share common setup or constraints between actions.
def set_portfolio
#portfolio = Portfolio.friendly.find(params[:id])
end
What's wrong with my app ?
portfolios_path is the collection path.
change it portfolio_path should fix it.
<%= form_for #portfolio, url: portfolio_path(#portfolio) do |f| %>
I guess you are going to use this form for creating new portfolio as well, so change it to <%= form_for(#portfolio) %> should fix it and will also work for both cases. form_for will submit to correct path.
I am trying to implement simple form in home#index page using:
<%= render "forms/form"%>
Form look like this:
<%= form_for(#form) do |f| %>
<% if #form.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#form.errors.count, "error") %> prohibited this form from being saved:</h2>
<ul>
<% #form.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :defect %><br />
<%= f.text_field :defect %>
</div>
<div class="field">
<%= f.label :region %><br />
<%= f.text_field :region %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
But when I access that page, I got this error message:
undefined method `model_name' for NilClass:Class
First of all I though it is because my model name is also Form, but then I checked Rails 3 reserved words, but there wasn't "form" !
Thanks in advance!
In home controller, set the instance variable #form in the index action as:-
def index
#form = Form.new
end
Your #form instance variable's value is nil. You should set it in controller.
I would like to capture email addresses with this form:
I have decided to create a model only for this and use the views and controller for a different model that is serving only static assets (think: newsletter sign-up).
<%= form_for (#signup) do |f| %>
<% if #signup.errors.any? %>
<div id="error_explanation">
<p><%= pluralize(#signup.errors.count, "error") %> prohibited this post from being saved:</p>
<ul>
<% #signup.errors.full_messages.each do |user| %>
<li><%= user %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :email_address %><br />
<%= f.email_field_tag :email_address %>
</div>
<div class="actions">
<%= f.submit %>
</div>
How do I get this form to work? I get undefined method signups_path for #<#<Class:0x00000004f1feb0>:0x00000004f09a98> exception, which is understandable (its looking for a SignupsController by convention).
But I want the form to display in a separate controller I call PagesController and send it to the Signup model.
Additional Info:
I tried passing url: pages_path in the form and get the same exception.
# view inside PagesController
<div class="four columns">
<%= render 'form' %>
</div>
#stub of model
class PagesController < ApplicationController
def index
#signup = Signup.new
end
def create
#signup = Signup.new(params[:signup])
end
end
try:
<%= form_for #sighup, :url => {:controller => :pages, :action => :index} do |f| %>
and I hope you didn't forget the
<% end %>
