I'm trying to render a liquid template that is stored in the database.
Here is my 'show' action in the controller:
def show
#organization = Organization.find_by_subdomain(request.subdomain)
#template = Liquid::Template.parse(Template.find(#organization.current_template).body)
#page = #organization.pages.find(params[:id])
respond_to do |format|
format.html { render #template.render('page' => #page), :template => false}
format.json { render json: #page }
end
end
However, when I visit the page, I get a "Template is Missing" exception with the following error (note that "testing testing" is the body attribute of the page object, which is currently the only thing being rendered in the template):
Missing template /testing testing with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :coffee, :haml]}.

* "/Users/ashercohen/.rvm/gems/ruby-1.9.3-p194/gems/devise-2.1.2/app/views"
Why is it trying to find another template, when I've specifically pass the :template => false argument? Is there something I'm missing here? I'm trying to bypass using any template files, as it seems like they shouldn't be needed here (though am not strongly opposed if I am wrong).
Because render almost always takes a filename, while #template.render('page' => #page) contains the plain html. You should invoke render like this:
render :text => #template.render('page' => #page), :content_type => :html

When I run my code on Cloud9 IDE, the next error appears:
Missing partial submissions/_submission with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}. Searched in: * "/usr/local/rvm/gems/ruby-2.3.0/gems/web-console-2.0.0.beta3/lib/action_dispatch/templates" * "/home/ubuntu/workspace/app/views" * "/usr/local/rvm/gems/ruby-2.3.0/gems/web-console-2.0.0.beta3/app/views"
I have a Submissions Controller and my create code is like this:
def create
#submission = Submission.new(submission_params)
respond_to do |format|
if #submission.save
format.html { redirect_to root_path}
format.json { render :show, status: :created, location: #submission }
else
format.html { render :new }
format.json { render json: #submission.errors, status: :unprocessable_entity }
end
end
end
I don't know which is my error and where to locate it.
Plus, a full stack text http://pastebin.com/YnyQeetU
The code of index.html.erb http://pastebin.com/fZbXd0Wk
This line of code is causing the problem.
<!--<%= render #submissions %>-->
#<!-- --> This is used to comment an HTML tag
If you do not want to render the partial you can simply comment that out as follows:
<%#= render #submissions %>
#<%# %> This is the way to comment embedded ruby code
Though the line is commented in HTML, the server tag is still being executed. Try to comment the server tag with <%#= link_to 'New Submission', new_submission_path %>. This will stop executing the server tag and you will not get the error.

In my routes.rb I have:
resources :workouts
In my workouts controller I have:
def show
respond_to do |format|
format.html
format.json { render :json => "Success" }
end
end
But when I go to /workouts/1.json, I receive the following:
Template is missing
Missing template workouts/show, application/show with {:locale=>[:en], :formats=>[:json], :handlers=>[:erb, :builder, :coffee]}. Searched in: * "/home/rails/app/views"
Which appears to show that the format is what it should be but it's still searching for a view. This same code functions in other controllers with identical setups just fine. Also, going to /workouts/1 for the html view seems to work just fine, though it also renders the html view properly when the format.html is removed.
Looks at the source code of render
elsif options.include?(:json)
json = options[:json]
json = ActiveSupport::JSON.encode(json) unless json.is_a?(String)
json = "#{options[:callback]}(#{json})" unless options[:callback].blank?
response.content_type ||= Mime::JSON
render_for_text(json, options[:status])
Pay attention to the third line. If the value of :json is a string, render won't call to_json automatically for this value.
So the value remains as string and render will go on to search template.
To fix, supply a valid hash even for trying purpose.
format.json { render :json => {:message => "Success"} }
You would try with /workouts.json
I installed wicked PDF and modified my controller :
def show
respond_to do |format|
format.pdf do
render :pdf => "file_name"
end
format.html
end
end
Here is how i link to the pdf : compte_contrat_path(c,:format=>'pdf')
It works for html (without the format) but fail for PDF with the following error :
Template is missing
Missing template contrats/show with {:locale=>[:fr], :formats=>[:pdf],

What am I doing wrong?
Thanks to henry I now know it was related to the format of the ERB.
I have found a way to reuse my html.erb files :
First i do the following in the controller
format.pdf do
render :pdf => "file.pdf", :template => 'contrats/show.html.erb'
end
Then when i use partials i call them like this :
render :partial => 'fullpath/toview.html.erb', :formats => [:html], :locals => { :mylocal=>#something }
For Rails 7, this is what works:
format.pdf do
render pdf: "file_name", template: "posts/show", formats: [:html]
end
Notice that template no longer have .html.erb and don't forget to include 'formats'.
I am trying to execute an AJAX routine with rails
the code runs normally but the response doesnt..
I get this error
Template is missing
Missing template line_items/create, application/create with {:locale=>[:en], :formats=>[:js, :html], :handlers=>[:erb, :builder, :coffee]}. Searched in: * "D:/ruby/depot/app/views"
I created the create.js.rjs inside line_items directory like the book Agile Web Development says it is to be, but the error insists..
#file line_items_controller.rb
def create
#cart = current_cart
product = Product.find(params[:product_id])
#line_item = add_product(#cart, product.id)
respond_to do |format|
if #line_item.save
format.html { redirect_to store_url }
format.js
format.json { render json: #line_item, status: :created, location: #line_item }
#...
end
end
end
and inside my create.js.rjs I got this
page.replace_html('cart', render(#cart))
Rjs is not a valid format anymore I guess. Use js.erb instead. Also manual you're following is outdated since none uses prototype anymore.
I have a controller method that returns JSON. But sometimes part of that JSON object should include a rendered, serialized HTML view. So my controller method has a line like this:
html = render_to_string :partial => 'foo/bar'
# ...
render json: {x: 'y', html: html}
But that fails because Rails is only looking for JSON views!
ActionView::MissingTemplate (Missing partial foo/bar with {:locale=>[:en], :formats=>[:json], :handlers=>[:erb, :builder, :coffee, :slim, :haml]}. […]
How can I solve this?
Update: I have gotten one "level" of layout to render_to_string as html using the below syntax, but the same error persists when that layout renders its own partials!
html = render_to_string :partial => "foo/bar.html.haml"
Surely there’s a solution here, right?
Update 2: render_to_string :action => 'method_in_this_controller' seems to be doing the trick.
Repeating Yanhao's answer because I ran into this exact problem and its what worked for me.
try:
html = render_to_string :partial => 'foo/bar', :formats=>[:html]
I am writing something like that in my action:
def show
...
respond_to do |format|
format.js { render :json => data }
end
end
May be it will help you.
Are you sure you have a file 'apps/views/foo/_bar.*'? I was able to render HTML as a JSON parameter with How do I render a partial to a string?
respond_to do |format|
format.html { redirect_to post_path(post) }
format.js {
render json: {
error: flash[:error],
content: (render_to_string partial: '/comments/comment', locals: {comment: comment}, layout: false )
}
}
end
