Displaying error messages in rails - ruby-on-rails-3

I seem to have trouble handling error messages. Here's my method:
def destroy
#user = User.find(current_user)
#authorization = Authorization.find(params[:id])
if #user.authorizations.count > 1
#authorization.destroy
redirect_to(user_path(current_user))
else
...
end
end
I don't want a user to delete their last authorization (say, Facebook) because then the user won't have any authorizations associated with it and the account is lost. I want to send an error message that says why the destroy method fails, but I'm just not sure how. Everything I've tried just doesn't work.
I've tried things like #user.errors.add => "error message"
But it just shows up blank. I think my problem is with using render. If I try, for example:
respond_to do |format|
#user.errors[:base] << "Sorry, you can't delete your only authorized service."
format.html render :template => "users/show"
end
I get a problem because rails starts looking for the partials in users/show inside the authorizations directory for some reason, presumably because I'm calling the authorizations controller from a users view.
Here's how I display the flash in my views:
def show_flash
[:notice, :errors, :alert].collect do |key|
msg = (flash[key].to_s + " (close)")
content_tag(:div, (content_tag(:a, msg, :class => "#{key}", :href => "#", :onclick => "$('messages').slideUp(); return false;")), :id => key, :class => "flash_#{key}") unless flash[key].blank?
end.join
end
I can get notices to appear just fine.

So, this seems to be working:
respond_to do |format|
format.html {redirect_to(#user, :alert => "Sorry, you can't delete your only authorized service.")}
end
But, this does not:
respond_to do |format|
format.html {redirect_to(#user, :errors => "Sorry, you can't delete your only authorized service.")}
end

Sending Information Through Twilio Using Rails

I have a Rails 3.2.18 app where I want to ship details of a call (includes name, age, and other information) to a recipient's phone that is already a field in the database.
So for instance a call has a unit assigned, and each unit has a medic (employee) assigned. In the medic model there's a phone field 281-444-555 (example number). What I want to be able to do in the calls controller is to send a SMS on create and update with the details of that call so it arrives on their phone as SMS.
I'm currently doing notifications to phones by using Email to SMS gateway 2813334444#vtext.com (example) using ActionMailer and it works "ok". But I really want to leverage Twilio.
Here's how I'm doing the mailer action to notify the medics of calls on create/update
calls_controller
def create
parse_times!
#call = Call.new(params[:call])
#call.dispatched_by = current_user.username
if #call.save
#call.send_mail(:new_call)
redirect_to calls_path, notice: "Call #{#call.incident_number} was successfully created.".html_safe
else
render :new
end
end
def update
parse_times!
#call = Call.find(params[:id])
respond_to do |format|
if #call.update_attributes(params[:call])
unless #call.call_status == "close"
#call.send_mail(:update_call)
end
format.html { redirect_to #call, notice: "Call #{#call.incident_number} was successfully updated.".html_safe }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: #call.errors, status: :unprocessable_entity }
end
end
end
call_mailer
def new_call(medic, call)
#call = call
#medic = medic
mail to: [#medic.medic_sms, #medic.medic_email], :cc => "noreply#company.com", subject: "New Call: #{#call.incident_number}"
end
def update_call(medic, call)
#call = call
#medic = medic
mail to: [#medic.medic_sms, #medic.medic_email], subject: "Updated Call: #{#call.incident_number}"
end
call model (mailer method)
def send_mail(mail_type)
units.each do |unit|
CallMailer.send(mail_type, unit.incharge, self).deliver
CallMailer.send(mail_type, unit.attendant, self).deliver
end
end
end
This is working just fine for mailing the phones and emails of the medics, but I would like to add something similar using Twilio where I can ship the call details to them via SMS in the create and update action.
If anyone can point me in the right direction, I'd appreciate it. I have a Twilio account already and would like to put it to good use.
Update 08/03/14
I think I figured this out and got it working in a basic fashion. But I'd like to see if there's someway to cleanly pass #call object data into the :body => section. Right now I'm having to iterate over the specific fields I want to send (which are about 10 different fields). It would be nice if I could create a partial or template and pass it to :body => similar to how ActionMailer works. Any thoughts?
calls_controller.rb (working)
def update
parse_times!
#call = Call.find(params[:id])
respond_to do |format|
if #call.update_attributes(params[:call])
unless #call.call_status == "close"
unless #call.unit_ids.empty?
send_sms
end
#call.send_mail(:update_call)
end
format.html { redirect_to #call, notice: "Call #{#call.incident_number} was successfully updated.".html_safe }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: #call.errors, status: :unprocessable_entity }
end
end
end
private
def send_sms
account_sid = 'AC5CCCCC'
auth_token = 'ATTTTT'
#client = Twilio::REST::Client.new account_sid, auth_token
#client.account.messages.create(
:from => '2814084444',
:to => #call.units.first.incharge.medic_phone,
:body => "incident_number #{#call.incident_number} patient name #{#call.patient_name}"
)
#client.account.messages.create(
:from => '2814084444',
:to => #call.units.first.attendant.medic_phone,
:body => "incident_number #{#call.incident_number} patient name #{#call.patient_name}"
)
end
end
Ok, I have this figured out now. I needed to do string interpolation in the :body element for Twilio to send the information out. Here is my final code and it's working and updated with a conditional to only fire Twilio if certain conditions are met.
calls_controller.rb
def update
parse_times!
#call = Call.find(params[:id])
respond_to do |format|
if #call.update_attributes(params[:call])
if !(#call.call_status == "close") && !(#call.unit_ids.empty?)
send_update_sms
#call.send_mail(:update_call)
end
format.html { redirect_to #call, notice: "Call #{#call.incident_number} was successfully updated.".html_safe }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: #call.errors, status: :unprocessable_entity }
end
end
end
def send_update_sms
account_sid = 'AC5CCCC'
auth_token = 'ATTTT'
#client = Twilio::REST::Client.new account_sid, auth_token
#client.account.messages.create(
:from => '28140844444',
:to => #call.units.first.incharge.medic_phone,
:body => "Updated: #{#call.incident_number}/#{#call.units.map(&:unit_name).join(", ")}/#{#call.patient_name}/#{#call.patient_age}/#{#call.patient_sex.try(:sex)}/#{#call.nature.try(:determinant)}/#{#call.special_equipments.map(&:name).join(", ")}/#{#call.traffic_type}/#{transfer_from_address}/#{transfer_to_address} CHECK EMAIL FOR FULL CALL INFO"
)
#client.account.messages.create(
:from => '2814084444',
:to => #call.units.first.attendant.medic_phone,
:body => "Updated: #{#call.incident_number}/#{#call.units.map(&:unit_name).join(", ")}/#{#call.patient_name}/#{#call.patient_age}/#{#call.patient_sex.try(:sex)}/#{#call.nature.try(:determinant)}/#{#call.special_equipments.map(&:name).join(", ")}/#{#call.traffic_type}/#{transfer_from_address}/#{transfer_to_address} CHECK EMAIL FOR FULL CALL INFO"
)
end
def transfer_from_address
if #call.transferred_from.nil?
#call.transfer_from_other
else
#call.transferred_from.try(:facility_name) + ' ' + #call.transferred_from.try(:facility_address)
end
end
def transfer_to_address
if #call.transferred_to.nil?
#call.transfer_to_other
else
#call.transferred_to.try(:facility_name) + ' ' + #call.transferred_to.try(:facility_address)

Rails 3.1 respond_to & render_403 problem

I'm not sure what it is. I've just upgraded to Rails 3.1 from 3.0.9 and here's what I get in my specs:
PeopleController edit action should require owner
Failure/Error: response.should render_template("/public/403.html")
expecting <"/public/403.html"> but rendering with <"search/_search_menu_item">
This is all over my specs in various controllers. I also have this code in my AppController:
def render_403
respond_to do |format|
format.html { render :file => "#{Rails.root}/public/403.html", :status => 403, :layout => false }
format.json { render :json => { :error => true, :message => "Error 403, you don't have permissions for this operation." } }
end
end
And this in PeopleController:
def edit
render_403 unless #person.account.id == current_account.id
end
I'm certain that format.html block gets executed (checked it). However the spec expectation fails. Wonder what is going on here.
(search/_search_menu_item is a partial that gets included onto every page, which basically means that the app layout gets rendered here instead.)
Update: I've replaced render_403 in #edit with render(:file => "#{Rails.root}/public/403.html", :status => 403, :layout => false) to see what happens - got the same result.
Ok, figured it out. Possibly not a Rails problem. At least the problem appears only when running the specs.
I've been checking if 403 pages are rendered with this:
response.should render_template("public/403.html")
Doesn't work no more. Replacing it with
response.status.should == 403
fixed the issue.

problem with RESTful forms in Rails 3

okay, so basically, I have a normal form for my model:
= form_for #operator do |f|
blah blah blah
In my operators controller, i have this:
def new
#operator = Operator.new
#operator.build_user
respond_to do |format|
format.html {}
end
end
def create
#user = User.create(params[:operator].delete(:user))
#user.update_attributes(:login => #user.email)
#operator = Operator.new(params[:operator].merge(:user => #user))
respond_to do |format|
if #operator.save
format.html {redirect_to new_operator_aircraft_path(#operator)}
else
format.html { render :action => "new", :error => #operator.errors }
end
end
end
very basic stuff. I have some validates_presence_of stuff in my model so naturally when I submit my form, it should show me that I have errors(and keep the fields I have filled up)
Right so far? yeah. The problem is, it seems I am posting to /operators and that's what renders. I seem to have forgotten about what happens in Rails2.3+ but shouldn't I be redirected to /operators/new again? or was that the intended behavior all along?
Here's what I think you are asking:
After I submit a form with errors, why does the URL
read "/operators" rather than
"/operators/new".
Thanks to resourceful routing, when submitting a form via POST to "/operators" the create action is called on the OperatorsController. If you encounter errors when saving your operator, you've instructed the controller to render the new action within the same request.
render :action => "new", :error => #operator.errors
This means a redirect is not occurring and therefore the URL remains "/operators".
If a redirect were to occur, you would lose all the state information of the #operator object in the current request, including the errors you encountered as well as the form values you just submitted.
In other words, working as intended.

Rails 3 - Nested Resources Routing - One to One relationship

Having some trouble with some nested resources routing. What I'm trying to do is link to a user's profile page for editing purposes. In my view it is written as:
<%= link_to "Edit Profile", edit_user_profile_path(current_user) %>
Which errors out with:
No route matches {:action=>"edit", :controller=>"profiles", :user_id=>#<User id: 1, email: "EDITEDOUT", hashed_password: "EDITEDOUT", created_at: "2011-01-20 18:30:44", updated_at: "2011-01-20 18:30:44">}
In my routes.rb file, it looks like so:
resources :users do
resources :profiles, :controller => "profiles"
end
I checked my Rake routes, and it gave me this as a valid option:
edit_user_profile GET /users/:user_id/profiles/:id/edit(.:format) {:action=>"edit", :controller=>"profiles"}
Which I am able to manually navigate to. For good measures, here's proof of my controller:
class ProfilesController < ApplicationController
def edit
#user = current_user
#profile = current_user.profile
end
def update
#user = current_user
#profile = current_user.profile
respond_to do |format|
if #profile.update_attributes(params[:profile])
format.html { redirect_to(orders_path, :notice => "Your profile has been updated.") }
format.xml { head :ok }
else
format.html { render :action => "edit" }
format.xml { render :xml => #profile.errors, :status => :unprocessable_entity }
end
end
end
end
Anyway, I've been having some problem tracking this down. Any pointers would help. For my DB design Profiles belong to Users in a one-to-one relationship. I'm hoping it's just something newbish I'm not noticing a new set of eyes might help.
If you look closely at your route, you'll see that it expects both a :user_id and an :id. The latter, in this case, refers to the user profile.
In order to tell Rails that you want that particular profile, you'll have to specify both the user and the profile in your link, like this:
edit_user_profile_path(current_user, #profile)
Now, Rails will use the first argument (current_user) for the :user_id part of the route, and the second argument (#profile) for the :id.

How to initiate new profile object (has_one) after successful registration with Rails3 & devise

So I have devise setup to perform registration. After registration the user is redirected to profiles#new however I can't attach profile to current_user id
Actually it doesn't work at all. Here is what I have in my profiles_controller.rb
# POST /profiles
def create
#profile = current_user.Profile.new(params[:profile])
respond_to do |format|
if #profile.save
format.html { redirect_to(#profile, :notice => 'Profile was successfully created.') }
else
format.html { render :action => "new" }
end
end
end
leading to undefined method `Profile' for #
So the User model has_one :profile ?
If so, you likely want:
#profile = current_user.profile.build(params[:profile])
Note that case ('profile' vs 'Profile') is important here.
I think that you should use
#profile = current_user.build_profile(params[:profile])
