actionview

This should be extremely straightforward and well documented, and I've done it several times, although there's something that's still killing me. I have a structure of partials calling nested partials. At some point one render call needs to pass an extra variable to the partial, although the rendering of the partial fails with a: undefined local variable or method `<variable name>' for #<#<Class:....> Here's my code for calling the render : = f.simple_fields_for :orders do |c| = render partial: "fields", locals: {f: c, step: f.object.step} though this doesn't work either: = f.simple_fields_for

I have a button_to that I want to perform a PUT action (there is only one thing that can be updated about this resource - it will be updated as being 'acknowledged', so there are no other form fields associated with firing the action). This is in my view (the controller is given explicitly because the button is on a view that belongs to another controller): <%= button_to "Acknowledged", :controller => 'practice_sessions', :id => @practice_session.id, :method => :put %> In my routes file, the resource has been declared as a restful resource: resources :practice_sessions The controller for this

I originally posted this as an issue on rails_api GitHub , but am now posting it here due to inactivity. I'm trying to use rails_admin with a Rails 5 API application. I included extra ActionController modules up to the point that I can either have a functioning rails_admin panel or working API requests. The issue seems to be that rails_admin depends on ActionView::Layouts , which after included causes issues for API requests. Gemfile: gem 'rails', '>= 5.0.0.beta3', '< 5.1' ... gem 'rack-pjax', github: 'afcapel/rack-pjax' gem 'remotipart', github: 'mshibuya/remotipart' gem 'kaminari', github:

How can I execute a image_tag method in a Rails console Run the console $ rails c Load helpers include ActionView::Helpers Execute the command image_tag('test.png') I got a strange error. Please help! Not sure why you're getting that error. It is strange. But the Rails Console exposes the helper methods through the helper variable. So this should work: helper.image_tag('test.png') OK... I found the solution. The error is showing only in Rails 3 but I fixed it by setting the config.action_controller.asset_host = "http://..." config.action_mailer.asset_host = "http://..." in my environemnt file

right now I'm creating an array and using: render :json => @comments This would be fine for a simple JSON object, but right now my JSON object requires several helpers which is breaking everything and requiring helper includes in the controller which seems to cause more problems than solved. So, how can I create this JSON object in a view, where I don't have to worry about doing anything or breaking anything when using a helper. Right now the way I'm making the JSON object in the controller looks little something like this? Help me migrate it to a view :) # Build the JSON Search Normalized

I thought that there should have been a simple solution to this, given that Rails 2.3 has this newfangled nested forms feature. Basically I want to create or update a user and assign them roles at the same time. It seems like I'm doing everything right but I get the error WARNING: Can't mass-assign these protected attributes: roles_attrributes . I even tried changing the view to user[permissions_attrributes][role_id] because I thought that maybe the join table was confusing Rails. Anyways, any suggestions on how this should actually work?
