Template Missing ... again! about cells HOT 21 CLOSED

Hi Steve,

what's your cell's class name (full constant path, please)? Maybe paste the entire cell class file here, along with where it's stored.

from cells.

Hey Nick - thanks for the quick response.

Cell is:

module User::Cell
  class Index < Trailblazer::Cell
    def no_items
      return "No Users" if model.size == 0
    end
  end
end

And lives in: app/concepts/user/cell/index.rb
Hope that's what you wanted to know.

Yepp, looks correct, and now, show me how you invoke that cell.

from cells.

From the UsersController ...

def index
    run User::Index
    render cell(User::Cell::Index, result["model"]), layout: false
end

I have tried different layout options as well.

result["model"] is ...

#<ActiveRecord::Relation [#<User id: 1, email: "[email protected]", other_attributes_here>]>

There is only one user at the moment.

from cells.

So where does the view template name come from? 🤔 Because User::Cell::Index, being a TRB::Cell, will try to render app/concepts/user/view/index.haml per default.

It must be a problem in that view, can you paste it?

from cells.

Yep, view template is in: app/concepts/user/view/index.haml
and is standard haml ...

- @title = "Listing Users"

- content_for :description do
  %p Users registered on this site.

- content_for :actions do
  = action_page_header new_user_path, 'Add User', 'plus'

.row
  .col-xs-12.col-sm-12.col-md-12.col-lg-12
    .sheet.sheet-condensed
      .sheet-inner
        %table.table
          %thead
            %tr
              %th Email
              %th
          %tbody
            etc ...

from cells.

Ok, so first of all, setting @instance variables is a no-go. That's just so wrong. Second, content_for is not supported in Cells, because it breaks with the idea of encapsulation.

What happens when you just say "hello!" in that template?

from cells.

Fair enough.

Changed index.haml to:

- %h1 Hello World

Same error.

from cells.

Correct me if I'm wrong, but is - %h1 ... valid HAML?

from cells.

Oops. Your quite right - slip of the keyboard.
Changed the template to ...

%h1 Hello World

Same issue.

from cells.

As I said, I also cloned your own sample app, bundled with a fresh install and got the same error, with your templates. Seems to be more than the haml template structure or location?

Just not sure why I'm the only one getting it.

from cells.

Hi! Which app did you clone?

from cells.

from cells.

Hey Nick. Any thoughts for me on this error. I'd love to use cells, but I guess I can just use normal rails renderer.

from cells.

The example app works for me, just checked. Is it maybe that the example app is using Slim while you're trying to use Haml? Have you tried with .slim?

from cells.

from cells.

If you want to use Haml, remove cells-slim from the Gemfile and replace with cells-haml (http://trailblazer.to/gems/cells/api.html#template-formats). Don't worry, we'll get you on da cells.

from cells.

Yep, have done that. As per previous comment ...

Here is my gem setup ...
rails (5.1.4)
cells (4.1.7)
cells-haml (0.0.10)
cells-rails (0.0.6)
reform-rails (0.1.7)
trailblazer-rails (1.0.4)
haml-rails (1.0.0)

I might try slim and hamlit as well - see if they make a difference. I'll let you know.

Hi people! I encountered the same issue with Cells (Template missing: view: * prefixes: *) and my search engine brought me there. I just had to rm -rf tmp/cache/ to fix the issue. Have a nice day!
