I have a controller that is supposed to display a flash message. The flash message is not displaying.
My only problem is the flash messages not showing up. If anyone could please give an explanation for this that would be awesome. I am guessing that my error is noobish but i do not know enough to explain what is happening.
Edit: I added my Log for this section
Edit: When i click the manage button with invalid information nothing happens. When i refresh the page the flash message shows up. I really just need the current page refreshed but it is not working. If anyone has any ideas please share them.
Edit: I have tried changing things to
redirect_to #department, :notice => "invalid Password"
I am still not able to get the flash message to show up.
EDIT: From this site it says flash now will be displayed in the view that you are rendering. But my rendered view is a partial. Can anyone at least let me know if i am on the right track. A little direction or thought other than my own?
This is the create method for my relationship.
def create
#department = Department.find(params[:manager_relationship][:department_id])
if #department.authenticate(params[:manager_relationship][:password])
current_user.manage!(#department)
respond_to do |format|
format.html { redirect_to #department }
format.js
end
else
redirect_to department_path#department, :alert => "Invalid Password"
end
end
This same code is used successfully in my sessions controller.
SessionsController
if user && user.authenticate(params[:session][:password])
sign_in user
redirect_back_or user
else
flash.now[:error] = 'Invalid email/password combination'
render 'new'
end
It is called from a partial
department/show.hmtl.erb
<% provide(:title, #department.department_name) %>
<div class="span8">
<%= render 'manage_form' if signed_in? %>

First, i can't see in your views where do you show the flash. You should do something like this in the view you want to display the message:
<% if flash[:success] %>
<p>
<%= flash[:success] %>
</p>
<% end %>
<% if flash[:error] %>
<p>
<%= flash[:error] %>
</p>
<% end %>
Second, when you do a redirection you should use flash[:success] = 'message' instead of flash.now[:success]. Use flash.now is you are not redirecting the user but just rendering a view.

I'm developing an application which uses CarrierWave as file manager (upload and download). It's used on my project model. It's kinda working because it upload the file but it doesn't refresh page nor show errors if there is any (but showed in the console -- whitelist error), in the other case (detroy) it shows the message correctly. I'll be really appreciated if you guys help me because i tested several things (redirect to root, etc) and nothing happens.

where is your image div?

<% end %>
<% end %>
</ul>
<%= render(:partial => 'projects/uploads/new') %>
</div>
something like this
<%= image_tag attachment.url %>
but you say it works on refesh?
I found the solution. The form was being submitted by ajax.
So i had to add to my form local: true parameter, like this:
<%= form_with(model: #project,local: true, :html => {multipart: true}, url: project_attachments_path(#project), method: :post) do |form| %>
...
<% end %>
And works like a charm.
Thanks to the readers.
I followed the answer given here to create a simple dynamic form (not nested). The idea is to invite several people with their email. Then I have an "Add Team Member" button to add the fields to enter the coworker email.
I get the following error but I don't know why:
ActiveModel::ForbiddenAttributesError in InvitationsController#create
The parameters:
{"utf8"=>"✓",
"authenticity_token"=>"zLs8DWkzO+bPc2jGhFptgc+BAGAwzr1kcn/hkX/6vQbQ/cDCzuqoGCMGUTcYHs+up7nBzHFiEXVcKustyL1KIA==",
"invitation"=>[{"email"=>"test#test.fr", "_destroy"=>"false", "user_id"=>"1"}, {"email"=>"test2#test2.fr", "_destroy"=>"false", "user_id"=>"1"}],
"commit"=>"Save Team Members"}
My create action and invitation_params in the controller:
def create
puts params[:invitation].to_yaml
params[:invitation].each do |invitation_params|
Invitation.create(invitation_params)
end
redirect_to invitation_path
end
def invitation_params
params.require(:invitation).permit(:id, :email, :user_id, :_destroy, :token)
end
My form:
<%= form_for(invitation) do |f| %>
<% if invitation.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(invitation.errors.count, "error") %> prohibited this invitation from being saved:</h2>
<ul>
<% invitation.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div id="container_invitations"></div>
<%= link_to "Add a New Team Member", add_invitation_path, :method => :post, :remote => true %>
<div class="actions">
<%= f.submit "Save Team Members", class: "cta2" %>
</div>
<% end %>
add_invitation controller action (to add the fields dynamically):
def add_invitation
respond_to do |format|
format.js
end
end
add_invitation.js.erb:
$('#container_invitations').append("<%= escape_javascript(render :partial => 'invitation_fields_render') %>");
$('.remove_fields').on('click', function(e) {
$(this).parent().remove();
});
_invitation_fields_render.html.erb (the partial with the fields)
<div class="new_invitation_row">
<%= email_field_tag "invitation[][email]", nil, placeholder: "Team Member Email", :required => 'required' %>
<%= hidden_field_tag "invitation[][_destroy]", nil, value: false %>
<a class="remove-link remove_fields dynamic" href="#"><i class="fa fa-trash fa-lg" title="Remove"></i></a>
<%= hidden_field_tag "invitation[][user_id]", nil, value: current_user.id %>
</div>
My invitation model:
class Invitation < ActiveRecord::Base
has_secure_token
belongs_to :user
end
Thank you.
UPDATE
I added the new params.permit line proposed by IngoAlbers. I still get the error. Here is the full stacktrace of the error:

The problem is that invitation is an array. So you actually need to permit the array in the invitation_params.
def invitation_params
params.permit(invitation: [:id, :email, :user_id, :_destroy, :token])
end
In addition you have a problem in the create action itself.
You don't actually use the permitted parameters, that was defined.
It should probably look like this:
def create
invitation_params[:invitation].each do |invitation|
Invitation.create(invitation)
end
redirect_to invitation_path
end
I'm trying to display images on the homepage with paperclip and I have unpermitted params and a routing error. I have tried various solutions including trying to pass in an array but I think this is happening because of my own lack of knowledge about rails.

I've added Pavans code to mine and i've also changed the params at the bottom which now gives me undefined method `create' for #. I think that's progress?
Unpermitted parameter: doc
You have multiple :true set for field doc, so doc should an array to accept the values. You should change the doc_params to below
def doc_params
params.require(:document).permit(:id, doc: [])
end
No handler found for
[#,
#original_filename="P1150645.jpg", #content_type="image/jpeg",
#headers="Content-Disposition: form-data; name=\"document[doc][]\";
filename=\"P1150645.jpg\"\r\nContent-Type: image/jpeg\r\n">]
You should also set multipart: true to the form to handle file uploads
<%= form_for #document, html: { multipart: true } do |f| %>
ActionController::RoutingError (No route matches [GET]
"/docs/original/missing.png")
Paperclip will try to find missing.png when an object doesn't have an uploaded file and you have tell Paperclip where to find it!
class Document < ApplicationRecord
has_attached_file :doc, :styles => { :medium => "250x250>", :thumb => "150x150>" }, :default_url => "/system/:attachment/:style/missing.jpg"
do_not_validate_attachment_file_type :doc
end
Update:
Your create action should look like below
def create
#document = Document.new(doc_params)
if #document.save
params[:document][:doc].each do |d| #iterate over multiple attached files
#doumnet.create(doc: d)
end
flash[:success] = "The document was added!"
redirect_to root_path
else
render 'new'
end
end
I'm trying to save a form, and I am so lost on why it refuses to save. Does anybod have a clue what might be wrong?
Here's the form code:
<%= form_for #service, url: services_path do |f| %>
<% #profiles.each do |profile| %>
<%= f.text_field :service_id, value: "#{profile.service_id}" %>
<div class="media">
<a class="media-left" href="#">
<%= image_tag profile.avatar, height: '45', width: '45', class: 'img-circle' %>
</a>
<div class="media-body">
<h4 class="media-heading"><%= profile.service_username %></h4>
<%= profile.service %>
</div>
</div>
<% end %>
<%= f.submit %>
<% end %>
and
#service = current_user.services.new
the association between them are:
user has_many :services
service belongs_to :user
and the services controller create looks like this:
def create
#service = current_user.services.new(service_params)
if #service.save
flash[:notice] = "success"
redirect_to root_url
else
flash[:alert] = "Unable to add"
redirect_to :back
end
end
my logs say:

Oops, minor edit below (#service.errors instead of #validation.errors):
From your logs, you can see that you got into the controller create method and the save failed. This is usually a validation problem but I can't tell from what you posted. I would put #service.errors into the flash instead of just "unable to add". This should help you and future users see what's going on when the create fails.
Hi I've set set of an appreciation controller that handles user's liking different posts. Each post has a like button and when I click it looks like the request goes through but the page doesn't refresh and update the button.
When I click like this is the log, it shows the unlike partial being returned but nothing changes:

Should the result of POST "/appreciations" be a redirect to http://localhost:3000/posts/3? You're using the :remote => true option of the form so I believe you need to change your controller to this:
respond_to do |format|
format.html { redirect_to #post}
format.js
end
And create a *.js.erb partial that does something like this:
<% unless current_user?(#user) %>
<% if current_user.likes?(#post) %>
$("#post_form").html("<%= escape_javascript(render('posts/unlike'))%>");>
<% else %>
$("#post_form").html("<%= escape_javascript(render('posts/like'))%>");
<% end %>
<% end %>
Basically I believe you're seeing no change because you're making an AJAX POST, but not doing anything with the result. You would need JavaScript that updates the innerHTML of a DOM element with the result of your post.
