Slim only accepts the block form of link_to - ruby-on-rails

The following:
= link_to 'New', new_photo_path
raises:
undefined method `stringify_keys' for "/photos/new":String
However, this works:
= link_to new_photo_path do
= 'New'
Why is that?

Undefined method `year' for nil:NilClass

I'm using monologue engine to creata a blog. I follow the readme file at https://github.com/jipiboily/monologue to config my app and database.
When i try to create a new article using monologue interface i get this error: undefined method 'year' for nil:NilClass.
Someone does know how to fix it?

I resolved using ruby 2.1.2.
Thanks to all!
It's actually a bug with rails, the fix is to update Rails as you can see in this commit
https://github.com/rails/rails/commit/e88da370f190cabd1e9750c5b3531735950ab415

Filterrific: ERROR: undefined method `empty?' for nil:NilClass

Having trouble getting the filterrific gem to work. I am getting the error "ERROR: undefined method `empty?' for nil:NilClass", it seems like the problem comes from the f.select in my form.
I have attached the relevant code in this link: https://github.com/jhund/filterrific/issues/26
I have been trying to get this gem to work all day with no luck. Great documentation, but just can't get it to work. Would appreciate any pointers.

I know it's been a long time, but if anyone is still wondering about the answer then please find it below:
It seems the error was due to a bug in the demo app, this was fixed and was committed to the demo app. Please find the answer in the below link (it is the same link as mentioned above)

<% end %>
This throws the error:
undefined method `param_key' for nil:NilClass
Full Trace:

As you mentioned, in this case it appears your association belongs_to :model was creating a method called model_name that was interfering with FormBuilder figuring out the intended model_name.
I also saw an identical error when trying to use fields_for #my_object (where #my_object didn't respond to model_name or param_key).
In my case I fixed the error with:
class MyObject
extend ActiveModel::Naming
end
which is used by form_for and fields_for in Rails 4.x

Rails: undefined method 'ingredients' for nil:NilClass

I am new to Rails so pardon if this question is relatively simple - I went through all the other similar errors on SO and no solutions were of use.
I am trying to print a list of ingredients from this api call and getting the error Rails: undefined method 'ingredients' for nil:NilClass. Any help is appreciated!
My code snippets are:
about page:
<% content_for :title do %>About<% end %>

<p>
This web application was created with
<%= link_to('Rails Composer', 'http://railsapps.github.io/rails-composer/') %>
from the <%= link_to('RailsApps project', 'http://railsapps.github.io/') %>.
Ingredients are <%= #recommendations.ingredients %>
</p>
model:
class Recommendations
require 'httparty'
attr_accessor :matches, :ingredients
def fetch_recipe
encoded_url = URI.encode("http://api.yummly.com/v1/api/recipes?_app_id=ca19779e&_app_key=125204344682094834d68637a8222adf&q=chicken&allowedCourse[]=course^course-Lunch&maxResult=100&start=1")
parsed_url = URI.parse(encoded_url)
HTTParty.get(parsed_url)
end
def initialize
recipe_hash = fetch_recipe
assign_values(recipe_hash)
end
def assign_values(recipe_hash)
recipe_response = recipe_hash.parsed_response['matches'][0]
self.ingredients = recipe_response['ingredients']
end
end
controller:
class RecommendationsController < ApplicationController
def home
#recommendations = Recommendations.new
end
end

add the recommendations instantiation to your about action too.
Better yet, refactor it into a method:
class RecommendationsController < ApplicationController
before_filter :new_recommendation, :only =>[:home, :about]
private
def new_recommentation
#recommendations = Recommendations.new
end
end
Ingredients of nil can, most logically, be also nil. Solve your problem by defining

nil

Rails 4.1.1 w/ pg_search - "PG::SyntaxError: ERROR: syntax error at or near "AS"" Bug

I updated from RoR 4.0.4 to 4.1.1 to apply the latest security patch and it appears pg_search broke.
Here's a error:
PG::SyntaxError: ERROR: syntax error at or near "AS"
LINE 1: ...sh', ''' ' || unaccent('banner') || ' ''')), 0))) AS pg_sear...
I'm searching via ajax but i don't think that is the issue based on the output above. I'm also using will_paginate but the branch I'm using is supposed to fix previous issues with rails 4.1.x and pg_search.
gem 'will_paginate', :git => 'https://github.com/nazgum/will_paginate.git' #until rails 4.1 will_paginate fixed
This is the code model where i'm executing the search:
include PgSearch
pg_search_scope :search, against: [:title, :body],
using: {tsearch: {dictionary: "english"}},
ignoring: :accents
def self.text_search(query)
if query.present?
search(query)
else
scoped
end
end
Everything was working prior to the RoR version bump - hoping someone might have some advice.
Here's the full stacktrace:

#supports.count(:all) should work, the #supports.count syntax got deprecated in rails 4.1.1
There is a good conversation here to clarify the problem.
This is weird - when i call
=#supports.count
the error is generated but it is a valid object. It's a bit hacky but this is working for now:
=#supports.to_a.count
