How to generate RABL view instead of HTML.erb
Am using the following command
rails generate controller users new create update edit destroy index show
Am getting all .erb views. I need rabl view.
Rabl is included in my GemFile
gem 'rabl'
I think you're asking for a generator which creates 'rabl' files just like scaffolding?
As far as I know,
Nope. There isn't a generator inside Rabl gem.
As ckruse said;
File -> new -> show.rabl

This is the first time I'm trying to build a gem. I use bundle gem MyGem
there are three directories inside MyGem. bin lib MyGem. I want to create controller model, helper inside it I tried scaffold but didn't worked for me any idea !!!
Use Rails Engines instead of a gem, which can include controllers, models, helpers, routes and other Rails elements.
I'm trying to generate .docx file via the caracal gem (https://github.com/trade-informatics/caracal). It's wrapped with their rails gem - caracal-rails.
I tried using partials in show.docx.caracal file with render partial: 'template' pointing to _template.docx.caracal file. There was no error, but content of partial was no included in generated document. There were only docx.ps from show and no docx.ps from partial.
If anybody using this gem tried partials - is there a way to use partials with this gem? (maybe it's not working because tilt which caracal uses has no compiler for these type of files?)
I am looking to not only customise my erb scaffold templates but also to add new templates.
In ScaffoldGenerator < Erb::Generators::Base I can see there there is a way to provide additional templates in %w(index edit show new _form).
So I have created a custom erb generator and templates directory in my application in lib/generators/erb/scaffold/.
However when I run rails g scaffold Something, my custom generator is not picked up by via scaffold_controller. Does this mean I need to provide a custom scaffold generator to use a custom scaffold_controller generator just so it can then use my erb generator?
I can also see the scaffold argument:
ScaffoldController options:
-e, [--template-engine=NAME] # Template engine to be invoked
# Default: erb
Am I able to provide my erb generator as the template engine to be used?
(Using Rails 4)
lib/templates/erb/scaffold is the correct path for rails scaffold.
Just in case...
model goes in /lib/templates/active_record/model/model.rb
controller goes in /lib/templates/rails/scaffold_controller/controller.rb
I'm trying to get custom scaffolding working from my engine.
I followed some tutorial on customizing Rails 3.2 scaffolding in a normal Rails App and put my customized templates in the engines /lib/templates/erb/scaffold directory but they don't get picked up by the app that includes the engine. Any suggestions?
Update:
I also tried to override the Rails ScaffoldGenerator's source_path and tried some other paths to put my template in, like:
lib/rails/generators/erb/scaffold/templates
zarazan's answer got me most of the way there, but there are a couple of things wrong with it. Here's what worked for me:
class Engine < Rails::Engine
config.generators do |g|
g.templates.unshift File::expand_path('../../templates', __FILE__)
end
end
Note that this goes in the generators section, not app_generators, and that the path is slightly different.
Also, I think the correct path to store your templates is lib/templates/erb/scaffold, optionally replacing erb with whatever language you are using (like haml or slim.) I know this works for slim. The file names are {_form,edit,index,new,show}.html.erb.
In the file that you declare your engine use this command:
class Engine < Rails::Engine
config.app_generators do |g|
g.templates.unshift File::expand_path('../templates', __FILE__)
end
end
It should shift the preference of what template folder Rails uses by default.
Now just put the template files in lib/templates/erb/scaffold/template_name.erb
Where template_name is one of the following: _form.html.erb, edit.html.erb, index.html.erb, new.html.erb, show.html.erb
Once you include the gem you should be able to use the rails generate scaffold command as normal.
Here is an example of an engine that overrides the default scaffolding in rails:
https://github.com/brocktoncg/gemboree
This is where the template directory is located:
https://github.com/brocktoncg/gemboree/tree/master/lib/templates/erb/scaffold
Are you talking about a controller template? Than you are using the wrong directory. Save your template at
lib/templates/rails/scaffold_controller/controller.rb
Have a look at http://xyzpub.com/en/ruby-on-rails/3.2/templates.html for an example.
I've created a generator for a controller in rails 3.
Now I want to use this generator as the default generator when using the scaffolding generator.
Is that possible?
The correct position for your customized controller file is lib/templates/rails/scaffold_controller/controller.rb
If you simply want to use your own controller template, you can just put it in lib/templates/rails/scaffold_controller/controller.rb
If you want to replace the scaffold_controller_generator code itself, for example, so that the controller scaffold generates additional class files. you can create lib/generators/rails/my_scaffold_controller/my_scaffold_controller_generator.rb with templates under lib/generators/rails/my_scaffold_controller/templates.
Remember to point rails at your new scaffold_controller in config/application.rb:
config.generators do |g|
g.scaffold_controller = "my_scaffold_controller"
end
For my_scaffold_controller_generator.rb you could copy from the railties gem under railties-3.x.x/lib/rails/generators/rails/scaffold_controller if you want to modify default behaviour, or inherit from it if you just want to add functionality:
require 'rails/generators/rails/scaffold_controller/scaffold_controller_generator'
module Rails
module Generators
class MyScaffoldControllerGenerator < ScaffoldControllerGenerator
source_root File.expand_path("../templates", __FILE__)
def new_funtionality
end
end
end
end
You can override the templates that Rails uses for its generators. In this instance, just place the file at lib/templates/scaffold_controller/controller.rb and modify it how you wish. The next time you run rails g scaffold [modelName] it will pick up this new controller template and use it.
This is covered in Section 6 of the Creating and Customizing Rails Generators official guide.
This seems to have changed slightly with Rails 4. You can see which template the generator will look for in the invoke line when the scaffold is generated, and your template folder name should match this:
rails generate scaffold blub
...
invoke responders_controller
If you're using rails g scaffold_controller blubs the location of the template should be:
lib/templates/rails/scaffold_controller/controller.rb
If you're using rails g scaffold blub the location of the template should be:
lib/templates/rails/responders_controller/controller.rb
If anyone is wondering why this isn't working in a default Rails 4 install, it's because jbuilder is inserting itself into the template path before the override location. I don't need jbuilder so I removed it, but I also reported an issue in Github. Hopefully it'll be fixed soon.
