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 have a nested route specifically around properties and downtowns. Downtowns have many properties.
The problem i'm having is that the edit form ended up getting quite large and I really would like to split it up in to a few partials for ease.
I've basically tried something similar to this here.
= simple_form_for([#downtown, #property]) do |f|
= render partial: "/properties/partial_test", locals: {resource: f }
The error I get when I do this is
ActionView::MissingTemplate in Properties#edit
Missing partial properties/_partial_test with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:raw, :erb, :html, :builder, :ruby, :coffee, :jbuilder, :haml]}
Right now all I have in the partial is filler text, but reading the error messaging, I'm assuming that the error is around how i'm trying to render the actual partial in my locals.
Would anyone have any thoughts or ideas on how to get this to work here?
Much thanks in advance! (also happy to share more code like my routes file or controller)
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/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
Im getting the following error when adding a export to CSV button on my Hotel Model.
Missing template hotels/index, application/index with {:locale=>[:en], :formats=>[:csv], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :haml, :jbuilder]}. Searched in:

* "/Users/kallan1/.rbenv/versions/2.2.1/lib/ruby/gems/2.2.0/gems/devise-3.4.1/app/views"
Thanks in advance and let me know if you need any more information
Rails expects to find views (e.g. html files) for the hotels/index, application/index (controller) actions. Did you define the appropriate view files?
EDIT Seems like a problem in your controller responses. This is approximately what you should have in the controller's index definition:
respond_to do |format|
format.html
format.csv { send_data #users.to_csv, filename: "example.csv" } # fill these with appropriate names
end
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').
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.
