I'm trying to load a customized spree page by inheriting from Spree::BaseController.
class PagesController < Spree::BaseController
layout 'spree_application'
def home
end
end
But I get a whole bunch of missing template errors
Template is missing
Missing template pages/home, spree/base/home, application/home with
{:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder,
:coffee, :rabl]}. Searched in: *
"/Users/mm/StoreOnline/app/views"...
This doesn't seem right. If I have to replace all those templates I might as well just use regular rails controllers/actions/views. So my question is - is this no longer supported in Spree version 1.1+?
Turns out I just had the controller defined in the wrong place. Really wish Spree had better documentation on this stuff.
Anyway, move it into app/controllers/spree/pages_controller.rb and it worked fine.

This is the error I'm getting whenever I'm accessing localhost:3000/cats:
Missing template cats/index, application/index with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:raw, :erb, :html, :builder, :ruby, :jbuilder]}. Searched in:
* "/home/mikael/RubyOnRailsLearning/NinetyNineCats/app/views"
* "/home/mikael/.rvm/gems/ruby-2.6.3/gems/actiontext-6.0.2.1/app/views"
* "/home/mikael/.rvm/gems/ruby-2.6.3/gems/actionmailbox-6.0.2.1/app/views"
My view templates are located like so:
app/views-layouts/cats/index.html.erb, show.html.erb
I have also tried removing them from cats and into the views folder.
My index controller action is this:
def index
#cats = Cat.all
render :index
end
The routes.rb file has only this inside:
resources :cats
This project worked fine yesterday. It could find the templates and render them just fine. But I wanted to restart it so I deleted the rails app folder without dropping the database and I remade it today. The database schema got uploaded into the rails app.
I can't think of anything that might be causing this problem besides me not dropping yesterday's database and not remaking it. (it's the only difference)
You wrote that your view is in
app/views-layouts/cats/index.html.erb
but Ruby on Rails conventions expect it in
app/views/cats/index.html.erb
I created a simple Gem for Ruby on Rails; the idea is that it provides some code/views for common actions (index/show/etc.) that I use in several of my applications. I would like to "DRY it up" in a Gem.
Creating the Concern went without problems, however, I can't quite seem to manage to render a view in my application.
For example, in my lib/rails_default_actions/rails_default_actions.rb I do:
module RailsDefaultActions
module DefaultActions
extend ActiveSupport::Concern
respond_to do |format|
format.html { render 'default/index' }
end
end
end
end
But an error is raised:
Missing template default/index with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :slim, :haml]}. Searched in:
* "/home/martin/myapp/app/views"
* "/home/martin/myapp/vendor/bundle/ruby/2.1.0/gems/devise-3.2.4/app/views"
* "/home/martin/myapp"
I eventually sort of managed to hack my way around this error, but it feels very kludgey and doesn't work in some scenarios. What is the correct way to include views in a gem?
I looked at creating an Engine, but that seems like overkill, since I just have a concern and a few views.
The "correct" way to do this since Rails 3 is to create an Engine; there's also a Rails guide for this, but creating a basic engine is as easy as:
module MyGemName
class Engine < Rails::Engine
end
end
When Rails looks for a view to render, it will first look in the app/views directory of the application. If it cannot find the view there, it will check in the app/views directories of all engines that have this directory.
I have the following in my views/patients/show.html.slim
== render 'era/header'
Of course, views/patients/era/_header.html.slim exists, though it throws a missing template error:
ActionView::MissingTemplate at /patients/12345
Missing partial era/header with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :slim, :haml]}.
Searched in: * "/home/pablo/code/rails/tarjira/app/views"
If I use == render 'patients/era/header' works, same with == render 'era_header' (assuming I have a views/patients/_era_header.html.slim file). The latter makes me think that rails search the actual directory (views/patients), so I don't understand why in the first case I have to prefix with patients/.
I'm using Rails 4.0.4.
To render a partial as part of a view, you use the render method within the view:
== render 'era_header'
This will render a file named _era_header.html.slim at that point within the view being rendered.
== render 'era/header'
This code will pull in the partial from app/views/era/_header.html.slim. Notice how the Rails is forming the path i.e, by prefixing app/views before the given path in render method call i.e., era/header. This is how render method is implemented in Rails.
Read the Rails Guide explanation for Naming Partials
The desire for partial rendering with relative paths seems to have a long history. There's an issue from 2011 and a pull request from 2015.
For now if you just need 1 extra level as described in your question you can place a callback in your application_controller.rb:
class ApplicationController < ActionController::Base
before_action :_append_view_path
def _append_view_path
append_view_path("app/views/#{controller_path}")
end
end
This way your views will gain the ability to use render('subfolder/partial') instead of render('controller/subfolder/partial').
Please help me figure out this rendering error occuring at Section 5.3 in the official Ruby On Rails Getting started tutorial (http://guides.rubyonrails.org/getting_started.html)
def create
render plain: params[:article].inspect
end
This code should output a hash of the parameters as mentioned. But it objects to the existence of a corresponding template.
The Template is missing error looks like
Missing template articles/create, application/create with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :raw, :ruby, :jbuilder, :coffee]}. Searched in: * "C:/Sites/blog/app/views"
render text:
intead of
render plain:
?
plain option was added in Rails 4.1. The Rails guide is for that version. I am guessing that your Rails version is lower than that. So, rails is ignoring this option and looking for a template named articles/create as you are in ArticlesController#create action. Obviously, the template doesn't exist so you get the error Template is missing.
I just started using Rails and am not sure what I'm not doing correctly.
In routes.rb I have
resources :pages
In app/controllers/pages_controller.rb I have
class PagesController < ApplicationController
def index
end
end
I have a layout in app/views/layouts/application.html.erb and a template in app/views/home/pages/index.html.erb which I want rendered when I request "/pages". However, I get the error
Template is missing
Missing template pages/index, application/index with {:locale=>[:en],
:formats=>[:html], :handlers=>[:erb, :builder, :coffee]}. Searched in:
* "/###/app/views"
I've been using stackoverflow for ages without posting, but so many different things seem to trigger this error that it's hard to find answers for my particular case. Also I'm a noob :3 Please help!
You say you have app/views/home/pages/index.html.erb to represent the index view for your pages resource. I think the home/ directory is not required.
In other words, your view file should be app/views/pages/index.html.erb.
It's looking to find it in app/views/pages/index but you have it in app/views/home/pages/index. That slight difference makes it so that the Rails convention is lost.
If you must keep your new directory hierarchy, do this on your controller:
class PagesController < ApplicationController
def index
render :partial => "home/pages/index"
end
end
But, by default, if you have a resource, like :pages, it will automatically look in app/views/pages.
I had this problem and I resolved it by just changing the folder name from car to cars. I had to change the folder name from singular to plural.
