I have the following #list received via MailChimp's API:
{"members"=>[{"email_address"=>"a#gmail.com"}, {"email_address"=>"b#gmail.com"}]}
And I'm trying to map it so that my #list is in the following format:
a#gmail.com, b#gmail.com, ...
However my attempts are unsuccessful with the following code in the controller:
respond_to do |format|
format.json {render json: #list{|email| {:email_address => email.email_address} }}
format.html
end
list = {"members"=>[{"email_address"=>"a#gmail.com"}, {"email_address"=>"b#gmail.com"}]}
list['members'].map{|m| m['email_address']}
# => ["a#gmail.com", "b#gmail.com"]
so render json: #list['members'].map{|m| m['email_address']} will get what you want

My application uses tickets and call_logs. I have these nested in each other, so that tickets can have many call_logs.
I am getting the error with [GET] "/call_logs"
I don't know what I am missing here.
I do have my routes nested in routes.rb
resources :tickets do
resources :call_logs
end

I believe I have an error in my url paths when directing to the call_log page, but I can't seem to find it. Any advice or tips would be appreciated, as I am a noob.
Thank you.
As you can see from the output of rake routes, You don't have a route that matches /call_logs. Since this is a nested resource route you have to prepend the tickets and ticket id: /tickets/<id>/call_logs.
Looks like you have done changes in routes.rb but not maintaining relation in Models. As rake routes say
ticket_call_logs GET /tickets/:ticket_id/call_logs(.:format)
Should be accessible by /ticket/id/call_logs , Now here "id" is ticket id. This will list all call logs for that particular ticket_id.
I have a simple Rails 3 example application that I'm trying to work out how to parse a JSON POST and insert the data into my applications database.
I have a basic Activities controller and model, the controller is as follows:
class ActivitiesController < ApplicationController
# GET /activities
# GET /activities.json
def index
#activities = Activity.order('created_at DESC').limit(10)
respond_to do |format|
format.html # index.html.erb
format.json { render json: #activities }
end
end
# GET /activities/1
# GET /activities/1.json
def show
#activity = Activity.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: #activity }
end
end
# GET /activities/new
# GET /activities/new.json
def new
#activity = Activity.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: #activity }
end
end
# GET /activities/1/edit
def edit
#activity = Activity.find(params[:id])
end
# POST /activities
# POST /activities.json
def create
#activity = Activity.new(params[:activity])
respond_to do |format|
if #activity.save
format.html { redirect_to #activity, notice: 'Activity was successfully created.' }
format.json { render json: #activity, status: :created, location: #activity }
else
format.html { render action: "new" }
format.json { render json: #activity.errors, status: :unprocessable_entity }
end
end
end
# PUT /activities/1
# PUT /activities/1.json
def update
#activity = Activity.find(params[:id])
respond_to do |format|
if #activity.update_attributes(params[:activity])
format.html { redirect_to #activity, notice: 'Activity was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: #activity.errors, status: :unprocessable_entity }
end
end
end
# DELETE /activities/1
# DELETE /activities/1.json
def destroy
#activity = Activity.find(params[:id])
#activity.destroy
respond_to do |format|
format.html { redirect_to activities_url }
format.json { head :no_content }
end
end

Because the POST will need to be made to a URL, I would imagine I need to define a new method:
def deploy_receive
data = JSON.parse(request.body)
end
What I am unsure of, is where to go from here. How would I cherry pick the attributes from the JSON and put them into various attributes in the Activities table?
Something like this?
def deploy_receive
data = JSON.parse(request.body)
#activity = Activity.new(params[:fault])
#activity.who = data.author
end
Any pointers would be appreciated!
If I understand correctly I think you're looking for something like what's below:
Routes File
match '/api/activity/new' => 'activity#deploy_receive', :via => [:post]
Activity Controller (assuming the POSTed data is in correct format)
def deploy_receive
#activity = Activity.new(params[:fault])
if #activity.save
render json: #activity
else
#activity = "error"
render json: #activity
end
end
If I understand it correctly; Rails will already do this for you if the right headers are set. Checkout: POST json to rails server
I'm new to Ruby on Rails, so please pardon my ignorance. My issue is that I cannot access the Rails project from the browser. I assume it has something to do with the Rails config, but I am having no luck so far.
State of the Project
I have existing logic (controllers, models, migrations, ...).
If I leave index.html in place, I see the Rails welcome page because it is apparently rendered before Rails tries to parse the URL.
If I disable index.html, I get the 'Something went wrong' message which is generated by Rails.
If I have the httpd.conf document root set to 'my.domain.com/public' I get the Rails error, but if I have it set to 'my.domain.com/', I get an error served up by Apache instead. (So that seems to be correctly configured.)
The error logs show this error: File does not exist: /var/www/html/my.domain.com/zombies when I hit the URL.
My Environment
Rails 3.2.6
Ruby 1.9.3
Apache 2.2.3
CentOS
If it matters, I'm simply following the tutorial at Rails for Zombies 2.
Thanks in advance!

Running rake assets:precompile seems to have fixed my issue. Thanks all.
i'm using rails3.0.10
def districts
#names = Node.where("name like ?", "%#{params[:term]}%").limit(5).map(&:name)
respond_to do |format|
format.json {render :json => #names}
format.xml {render :xml => #names}
end
end
render xml get right names
but render json make the names is encoded like => ["name1", "name2", "\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd\ufffd"]
i want to get right names in their right language
any help?
Thanks in advance
before sending the response you must force the strings to be UTF-8
add this line for the above code
#names.map{|name| name.force_encoding('UTF-8')}
this will loop the array of names and force them to be encoded from ASCII-8BIT to UTF-8
so my method will be
def districts
#names = Node.where("name like ?", "%#{params[:term]}%").limit(5).map(&:name)
#names.map{|name| name.force_encoding('UTF-8')}
respond_to do |format|
format.json {render :json => #names}
format.xml {render :xml => #names}
end
end
you can also modify tour model Node like
class Node < ActiveRecord::Base
def name
super().force_encoding('UTF-8')
end
end
i'm sure from this code , it works correctly
Thanks

As it's not currently possible for me to use a json templating engine (jbuilder or rabl) as per Rails3 ActionView Template Handlers doesn't work on Production Server I'm wondering how to best change this controller action to include a custom node with as_json (or something else)
class Mobile::AndroidUsersController < SecureMobileUserController
skip_before_filter :authorize, :only => :create
respond_to :json
# POST /mobile_users
# POST /mobile_users.xml
def create
#mobile_user = AndroidUser.find_by_auth(params[:mobile_user][:auth])
unless #mobile_user
#mobile_user = AndroidUser.new(params[:mobile_user])
else
#mobile_user.attributes = params[:mobile_user]
end
respond_to do |format|
if #mobile_user.save
format.json #Add a custom token node here
else
:unprocessable_entity }
format.json { render json: #mobile_user.errors, status: :unprocessable_entity }
:unprocessable_entity }
end
end
end
end
I just need to add a custom node called token that has a value that I get from calling a method on the MobileUser class
:token => MobileUser.next_token
You can change the call to as_json like this:
format.json {render :json => #mobile_user.as_json(:methods => [:next_token])}
